FIG. 1 is a view for describing the construction of a system for producing hydrogen and oxygen mixture gases according to the present invention; and

FIG. 2 is a view of a nano particle formation part of FIG. 1.

MODES FOR CARRYING OUT THE INVENTION

The system for producing a mixture of hydrogen and oxygen gases according to the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a view for describing the construction of a system for producing a mixture of hydrogen and oxygen gases according to the present invention, and FIG. 2 is a view illustrating a nano particle formation part of FIG. 1.

As shown therein, the system for producing a mixture of hydrogen and oxygen gases according to the present invention comprises an electrolyte storage tank 10 for storing electrolyte as electrolysis is performed with respect to water; an electrode unit 20 which is formed of pluralities of positive electrodes 25 and negative electrodes 26 and includes first and second lines 21 and 22 connected with a lower side of the electrolyte storage tank 10, and a third line 23 for supplying a mixture of hydrogen and oxygen gases to the electrolyte storage tank 10; a circulation pump 30 which is connected with the first line 21 or the second line 22 for thereby circulating electrolyte between the electrolyte storage tank 10 and the electrode unit 20; a mixture gas input prevention plate 40 which is installed between the portion connected with the first and second lines 21 and 22 and the portion connected with the third line 23 in the interior of the electrolyte storage tank 20 for preventing the mixture of hydrogen and oxygen gases, which is inputted through the third line 23, from being inputted into the first and second lines 21; a mixed gas separation filter 50 for separating the hydrogen and oxygen mixed gas from the electrolyte; a collection part 60 which is formed on an upper side of the mixed gas separation filter 50 for thereby collecting the hydrogen and oxygen mixed gases which are separated by means of the mixed gas separation filter 50; a first filter unit 70 for storing water therein for preventing the hydrogen and oxygen gas mixture, which is inputted from the collection part 60, from being reverse inputted into the collection part 60; a first gas line 75 connected with the collection part 60 and the first filter unit 70; a second filter unit 80 which enhances the purity of the hydrogen and oxygen gas mixture inputted from the first filter unit 70 and stores organic agent for preventing a reverse input into the first filter unit 70; a second gas line 85 for connecting the first and second filter units 70 and 80. a reverse flame prevention part 90 for preventing combustion flame from being reverse inputted into the second filter unit 80 when the hydrogen and oxygen gas mixture inputted from the second filter unit 80 is burned; and a nozzle N connected with the reverse flame prevention part 90 for spraying hydrogen and oxygen gas mixture.

A water level detection part 14 is installed in the interior of the electrolyte storage tank 10 for detecting the water level of the electrolyte. The water level detection part 14 measures the amount of electrolyte consumed in the electrolyte storage tank 10 and allows the water to be supplied from the water supply tank(not shown) to the electrolyte storage tank 10. Here, the water level detection part 14 can be implemented in various forms. For example, it could be implemented in a float method or a sensor method. The water level detection part 14 and the water supply tank are known in the field, so their descriptions will be omitted.

A valve V is installed in a lower side or an upper side of the electrolyte storage tank 10 for filling water.

The electrode unit 20 is provided for producing hydrogen and oxygen gases by hydrolysis-treating water and includes a plurality of negative electrodes 25 and a plurality of positive electrodes 26. The surfaces of the negative and positive electrodes 25 and 26 are nano polished for efficient electrolysis occurrence.

Here, the nano polishing process is to nano polish the surfaces of the negative and positive electrodes 25 and 26. The friction forces of the surfaces of the negative and positive electrodes 25 and 26 can be minimized with the helps of nano polishing, so that the produced oxygen and oxygen bubbles can be easily detached. In particular, when the sizes of the substance change to nano sizes in a bulk state, mechanical, electrical, magnetic and optical properties change. The electrolysis of water can be more efficiently performed by nano polishing the negative and positive electrodes 25 and 26 and by changing physical properties.

Tourmaline photo catalyst could be attached to the surfaces of the negative and positive electrodes 25 and 26. The tourmaline photo catalyst is plasticity-formed at a temperature of about 1300° C. after tourmaline photo catalyst is ground from a few micron sizes to a few nano meter sizes. The tourmaline photo catalyst can be attached to the negative and positive electrodes 25 and 26 using a certain adhesive. Tourmaline is a mineral which has a hexagonal crystal structure, which produces electricity by means of a friction and produces a lot of anion. Lots of hydrogen and oxygen gases can be produced by promoting electrolysis. Tourmaline is ground to powder and is plasticity-formed as photo catalyst having enormous micro pores which help increase the contact area with the electrolyte. Namely, it is possible to promote the electrolysis of electrolyte by attaching tourmaline photo catalyst to the negative and positive electrodes 25 and 26.

It is obvious that the negative and positive electrodes can be implemented by molding the tourmaline photo catalyst in a sheet shape.

The negative and positive electrodes are positioned in the interior of the box sealed.

The circulation pump 30 is installed in the first line 21 or the second line 22 and allows the electrolyte to circulate between the electrolyte storage tank 10 and the electrode unit 20. In the present invention, it is described that the circulation pump 30 is installed in the first line 21, and the electrolyte is transferred to the electrode unit 20 through the first line 21.

A nano particle formation part 35 could be installed in the first line 21 or the second line 22 for splitting the particle of the electrode, into small parts, transferred to the electrode unit 20 by means of the circulation pump 30 while causing small pressure change. In the present invention, it is described that the nano particle formation part 35 is installed in the first line 21. For the above structure, the nano particle formation part 35 comprises a body 36 which is installed in the first line 21, an impeller 37 which is installed in the interior of the body 36 at an inclined angle for rotations by means of the electrolyte, and a bearing 38 or a bushing which supports the shafts of the impeller 37. At this time, the impeller 37 is configured as having widened in the direction of the electrode unit 20. The electrolyte transferred by means of the circulation pump 30 rotates the impeller 37, and the impeller 37 divides the electrolyte into small parts while vibrating the same. Since the impeller 37 is configured as having widened in the direction of the electrode unit 20, it is possible for the impeller 37 to divide smaller parts while vibrating the same when passing through the widening portions of the impeller 37. The divided and vibrating electrolyte is inputted into the electrode unit 20, so electrolysis can occur more efficiently with the helps of the negative electrode 25 and the positive electrode 26.

In addition, the electrolyte vibrated by means of the nano particle formation part 35 impacts the bubbles of the hydrogen and oxygen gases formed on the surface of the negative and positive electrodes 25 and 26 for thereby more efficiently detaching the bubbles.

The hydrogen and oxygen gas mixture of the present invention might be made smaller without adapting the circulation pump 30. When the hydrogen and oxygen gas bubbles generated from the electrode unit 20 are inputted into the electrolyte storage tank 10, since the pressure of the interior of the electrolyte storage tank 10 increases, the electrolyte can naturally circulate through the first and second lines 21 and 22. When the circulation pump 30 is applied, since the electrolyte is forcibly circulated, the electrolyte efficiency can be enhanced.

The mixture gas input prevention plate 40 is provided so as to prevent the hydrogen and oxygen gas bubbles, which are inputted through the third line 23, from moving in the direction of the first and second lines 21 and 22, for which the mixture gas input prevention plate 40 is formed of a plate material with holes or a mesh-shaped plate material.

The mixture gas input prevention plate 40 might be implemented as tourmaline photo catalyst is attached to a plate material with holes or a mesh shaped plate material. The tourmaline photo catalyst might be implemented in such a manner that tourmaline is ground into powder from a few micro sizes to a few nano meters and is plasticity-formed at a temperature of about 1300° C. Here the tourmaline is a mineral having a hexagonal crystal structure like a crystal. When surrounding temperature increases, it produces a lot of anion, which promotes electrolysis of electrolyte. Since the tourmaline is ground into powder and is plasticity-formed, enormous micro pores are formed in the photo catalyst, which leads to increase the contact area with electrolyte. It is possible to promote the electrolysis of electrolyte by attaching the tourmaline catalyst to the plate material of the mixture gas input prevention plate. In particular, the temperature of water increases to about 80˜90° in the course of electrolysis, so the tourmaline photo catalyst produces a lot of anion, whereby the electrolysis can be promoted more.

The mixture gas separation filter 50 separates the hydrogen and oxygen gases generated from the electrode unit 20 from the electrolyte for thereby collecting only the pure hydrogen and oxygen mixture gases in the collection part 60. It is preferred that in the mixture gas separation filter 50, the mesh net is equipped with photo catalyst or preferably tourmaline catalyst. The tourmaline photo catalyst might be implemented as the photo catalyst is coated on a mesh net or it is originally contained in the mesh net when it is manufactured. The mixture gas separation filter 50 is able to filter foreign substances contained in the interior of the mixture of rising hydrogen and oxygen gases, namely, foreign substances generating from the negative and positive electrodes or foreign substance contained in the water supplied, for thereby collecting only the mixture of pure hydrogen and oxygen gases. In particular, since photo catalyst is formed in the mixture gas separation filter 50, the foreign substances can be more effectively removed with the help of the photo catalyst operation.

The collection part 60 is like a space formed in the upper side of the mixture gas separation filter 50 for collecting the mixture gases separated by means of the mixture gas separation filter 50.

The first filter unit 70 is configured to remove the hydrogen and oxygen gases inputted from the collection part 60 to the first gas line 75 for thereby producing a high purity mixture gas. In addition, it has a reverse flame prevention function for preventing the hydrogen and oxygen mixture gas from being reverse-inputted into the collection part 60. The first filter unit 70 comprises a water storing part 71 which is connected with the first gas line 75 for storing water therein, a first catalyst storing part 72 installed in an upper side of the water storing part 71 for storing catalyst, and a first Venturi part 73 for connecting the water storing part 71 and the first catalyst party 72.

In the water storing part 71, a first sub-collection part 71a is formed above the water of the same for collecting hydrogen and oxygen gas mixture which has passed through the water.

Catalyst generally is stored in the first catalyst storing part 72. Catalyst is like tourmaline photo catalyst or platinum catalyst. The first catalyst storing part 72 removes a compound-type foreign substance with the helps of catalyst operation.

The Venturi part 73 is basically adapted to uniformly mix the hydrogen is gas and the oxygen gas which pass through the same, while preventing the mixed gases, which has moved to the first catalyst storing part 72, from being reverse-inputted into the first sub-collection part 71a, for which operation at least one or two fine flow paths are formed in the interior of the first Venturi part 73. More preferably, fine flow paths are formed in a screw shape. The diameter of the path formed in the first Venturi part 73 preferably is in a range of 0.2 mm through 10 mm.

Actually, the hydrogen and oxygen gases, which are inputted into the water storing part 71, might be partially not mixed. However the hydrogen and oxygen gases can naturally and uniformly mixed while passing through the flow path of the first Venturi part 73.

A water level detection part 74 is installed in the interior of the water storing part 71 for detecting the level of water. The water level detection part 74 measures the amount of water consumed in the water storing part 71 for thereby reliably supplying water from the water supply tank(not shown) to the water storing part 71. The water level detection part 74 can be applied in various types. For example, it might be applied in a float method or a sensor type. Since the water level detection part 74 and the water supply tank are known in the field, their descriptions will be omitted.

A first foreign substance removing filter 76 might be connected at the end of the first gas line 75 positioned in the interior of the water storing part 71. The first foreign substance removing filter 76 is configured to remove the foreign substances contained in the hydrogen and oxygen gas mixture.

With the helps of the structure of the first filter unit 70, the foreign substances contained in the hydrogen and oxygen mixture gases, which are inputted through the first gas line 75, are removed by means of the first foreign substance removing filter 76. The foreign substance-removed mixture gas moves up and is connected in the first sub-collection part 71a, so the gas does not reverse-flow to the first gas line 75. The mixture gas collected in the first sub-collection part 71a is more uniformly mixed while passing through the first Venturi part 73, and the compound foreign substances are removed while passing through the first catalyst storing unit 72, so high purity mixture gas can be obtained.

The second filter unit 80 removes again the foreign substances from the hydrogen and oxygen gas inputted from the first filter unit 70 through the second gas line 85 for thereby producing high purity mixture gas while performing a reverse flame prevention function which prevents a reverse flow into the first filter unit 70, for which the second filter unit 80 comprises an organic agent storing part 81 connected with the second gas line 85 for storing an organic agent therein, a second catalyst storing part 82installed in an upper side of the organic agent storing part 81 for storing catalyst, and a second Venturi part 83 for connecting the organic agent part 81 and the second catalyst storing part 82.

In the organic agent storing part 81, a second sub-collection part 81a is formed in the upper side of the organic agent for collecting hydrogen and oxygen mixture gases which have passed through the organic agent.

Catalyst is stored in the second catalyst storing part 82, and catalyst is formed of tourmaline photo catalyst or platinum catalyst. The second catalyst storing part 82 removes compound type foreign substances with the helps of catalyst operation.

The second Venturi part 83 is applied for forming mixed gas by uniformly mixing hydrogen gas and oxygen gas while preventing the mixed gas, which has moved to the second catalyst storing part 82, from being reverse-inputted into the second sub-collection part 81a, for which operation at least one or two flow paths are formed in the interior of the second Venturi part 83. More preferably, fine flow paths are formed in a screw shape. It is preferred that the diameter of the flow path formed in the second Venturi part 83 is in a range of 0.2 mm through 10 mm.

The hydrogen gas and oxygen gas inputted into the organic agent storing part 81 after passing through the first filter unit 70 might not be still mixed partially, however they are more uniformly mixed while passing through the flow path of the second Venturi part 83.

The water level detection part 84 is installed in the interior of the organic agent storing part 81 for detecting the level of organic agent. The water level storing part 81 measures the amount of organic agent consumed, and allows the organic agent to be supplied from the organic agent supply tank (not shown) to the organic agent storing part 81. Here the water level detection part 84 might be implemented in various types. For example, it might be implemented in a float type or a sensor type. Since the above water level detection part 84 and organic agent supply tank are well known in the field, the descriptions of the same will be omitted.

With the helps of the second filter unit 80, the foreign substances contained in the hydrogen and oxygen gas, which is inputted through the second gas line 85, is removed by means of the second foreign substance filter 86. The foreign substance-removed mixture gas moves up and is collected in the second sub-collection part 81a, so it does not reverse-flow into the second gas line 85. The mixed gases collected in the second sub-collection part 81a are more uniformly mixed while passing through the second Venturi part 83, and the compound type foreign substance is removed while passing through the second catalyst storing part 82, so a high purity mixed gas is obtained.

The organic agent is used for an easier ignition of the mixture gas which passes through the organic agent. It is possible to change the colors of flames by changing the kinds of organic agents. The quality of gas can be improved by lowering the ignition temperature for an easier ignition of the hydrogen and oxygen mixture gas. It is possible to generate a certain smell for checking when the leakage of hydrogen and oxygen mixture gas by adding a certain additive. In order words, the organic agent is applied to ease the ignition of the hydrogen and oxygen mixture gas. Here the organic agent might be formed of alcohol which has a lower ignition temperature and is widely known.

The reverse flame prevention part 90 prevents a reverse flow of the hydrogen and oxygen mixture gas, which has been discharged from the second filter unit 80, into the second filter unit 80, for thereby preventing the combustion flame from flowing into the second filter unit 80 in the burning course of hydrogen and oxygen mixture gases. The reverse flame prevention part 90 is a safety apparatus of the system for producing hydrogen and oxygen gases according to the present invention. Since the reverse flame prevention part 90 is well known in the art, the descriptions of the same will be omitted.

A check valve 95 is installed between the reverse flame prevention part 90 and the nozzle N for finally preventing the reverse flame. The check valve 95 allows the gas to flow only from the reverse flame prevention part 90 to the nozzle N and is formed of a spring for applying an elastic force only in the direction of the nozzle N, and a ball which is elastically biased by means of the spring for selectively opening and closing the entrance of the nozzle N direction. Since the check valve 95 is well known in the field, the descriptions of the same will be omitted.

With the above structure of the present invention, when DC electric energy is applied to the electrode unit 20, electrolysis occurs between the negative electrode 25 and the positive electrode 26, so hydrogen and oxygen bubbles occur, and the gases are mixed and are inputted into the interior of the electrolyte storage tank 10 through the third line 23. At this time, the mixture gas input prevention plate 40 prevents the hydrogen and oxygen gas bubbles from being moved into the first line 21 through the third line 23.

The hydrogen and oxygen mixture gases are collected into the collection part 60 through the mixture gas separation filter 50. At this time, the mixture gas separation filter 50 separates the hydrogen and oxygen mixture gas from the electrolyte for thereby collecting only pure hydrogen and oxygen mixture gases.

The hydrogen and oxygen mixture gases collected in the collection part 60 passes through the first gas line 75→the first filter unit 70→the second gas line 85→the second filter unit 80 and then the reverse flame prevention part 90→the check valve 95→the nozzle N and is used as a combustion gas.
