However, the above conventional techniques have the following problems.
In (1) (Patent Document 1), the electrode plates on both ends of the plurality of electrode plates are connected to one electrode of the power source, and the center electrode plate is connected to the other electrode of the power source. As the number of electrode plates arranged between the electrode plate and the central electrode plate increases and the distance between the electrode plates on both ends and the central electrode plate increases, the bipolar electrode structure approaches and the electrodes on both ends Although the voltage between the plate and the central electrode plate must be increased and the electrode plate is susceptible to corrosion, the electrodes are connected to both ends of the electrode plate and the central portion. However, the number of electrode plates arranged between them is not specified, and there is a problem that the efficiency and reliability of electrolysis are lacking.
(2) Moreover, in (patent document 1), seawater is distribute | circulated to the electrolysis chamber comprised by laminating | stacking alternately the several electrode plate which has a seawater circulation hole, and a some frame-shaped gasket, and performs electrolysis. However, since the outer shape of the electrode plate and the gasket are the same, and the outer periphery of the electrode plate is exposed to the outside, there is a high possibility that the electrode plate will be touched by the hand, and the handleability is poor. Had.
(3) In Patent Document 2, a large number of electrode plates and spacers are connected alternately to each other, and the inner peripheral surface of the spacer is sealed with an O-ring to form an electrolyte filling chamber. The chamber is narrower than the electrode plate, and the contact area between the electrolyte and the electrode plate is reduced, so that the entire area of the electrode plate cannot be used effectively, and the efficiency of electrolysis and resource saving are lacking. Was.
(4) In addition, (Patent Document 2) has a problem that the outer periphery of the electrode plate protrudes outwardly from the spacer and is exposed to the outside, so that the electrode plate is easy to touch and lacks in handleability. Was. In addition, if the positive and negative electrodes of the power supply are alternately connected to these electrode plates, there is a risk of short-circuiting due to adhesion of foreign matter etc. to the electrode plates, and there is a lack of operational reliability and maintainability. Had problems.
(5) In Patent Document 3, a mounting groove for vertically mounting a plurality of electrode plates is formed, and only an electrode plate insulating support frame for arranging and supporting the electrode plates in the electrolytic chamber at a constant interval is required. In addition, an insulating plate must be arranged between the joint contact parts of the pair of electrolytic cell cases to insulate the electrolytic cells from each other. The structure is complicated and the number of parts is large. The problem was lacking in productivity and mass productivity.
(6) In addition, in (Patent Document 3), since the electrolysis chamber is surrounded by the electrode plate insulating support frame and the electrolytic cell case, heat dissipation is lacking, but no measures are taken to prevent temperature rise. , Had the problem of lack of stability and durability of operation.
(7) In (Patent Document 4), two types of large and small square electrode plates of different sizes are overlapped at equal intervals, and the small electrode plate portion is used as an electrolysis tank. The outer peripheral portion of the electrode could not be effectively used as an electrode, and there was a problem that the efficiency of electrolysis and resource saving were lacking.
(8) Further, in (Patent Document 4), since all the small electrode plates are each edged with an insulator at four edges, it is difficult to apply a voltage by directly connecting to the electrode of the power source. When driving in a bipolar system using only a large electrode plate, the voltage must be increased, and the electrode plate is likely to corrode and lacks practicality and durability. It was. When driving in a monopolar system using only a large electrode plate, it is easy to touch the electrode plate because of the large electrode plate placed outside the electrolysis tank, and lacks handling. At the same time, a short circuit may occur due to adhesion of foreign matter or the like to the electrode plate, and there is a problem that operation reliability and maintainability are lacking.
It wasn't.

  The present invention solves the above-described conventional problems, has a simple configuration, has a small number of parts, is easy to assemble and disassemble, is excellent in mass productivity and maintainability, and effectively utilizes the entire electrode to generate oxygen gas and hydrogen gas.

In order to solve the above problems, the combustion gas generator of the present invention has the following configuration.
The combustion gas generator according to claim 1 of the present invention is a combustion gas generator that generates a combustion gas containing oxygen gas and hydrogen gas by electrolyzing an electrolyte solution, and 3n (where n is A natural number of 3 or more) and spacers alternately arranged with each of the electrodes, and the electrodes are disposed at the (3i-2) th and (3i) th positions for voltage application and grounding. Float electrode group (where i = 1 to n is a natural number) and (2 + 6 (j−1)) th first electrode group to which positive voltage or negative voltage is applied (where j = 1 to 1) n1, n1 is a natural number of 2 or more), and a second electrode group (5 + 6 (k−1))-th arranged and applied with a voltage having a polarity opposite to that applied to the electrodes of the first electrode group ( Provided that k = 1 to n2 and n2 is a natural number of 1 or more) An electrolytic reaction opening facing the electrode; a combustion gas recovery opening extending above the electrolytic reaction opening; and a step formed on the periphery of the electrolytic reaction opening. And at least one electrode receiving claw portion to be engaged, and has an electrolyte solution filling portion filled with the electrolyte solution.
This configuration has the following effects.
(1) By having 3n electrodes (where n is a natural number of 3 or more) and spacers alternately arranged with each electrode, a large number of electrodes can be held easily and reliably at a predetermined interval. It is possible to prevent temperature rise and occurrence of short circuit, and it is excellent in handling, durability, operational reliability and stability.
(2) A float electrode group (where i = 1 to n is a natural number) in which the electrodes are arranged in the (3i-2) th and (3i) th and are not applied with voltage or ground, and (2 + 6 (j-1) ) First electrode group to which positive voltage or negative voltage is applied (where j = 1 to n1, n1 is a natural number of 2 or more), and (5 + 6 (k−1)) th electrode group. Since it has the 2nd electrode group (however, k = 1-n2 and n2 are 1 or more natural numbers) to which the voltage of the reverse polarity is applied to the voltage applied to the electrode of the 1st electrode group, the electrode of the 1st electrode group A positive voltage or a negative voltage is applied to the second electrode group, and a voltage having a polarity opposite to that of the first electrode group is applied to the electrodes of the second electrode group. Each electrode of the float electrode group disposed adjacent to each other is separated from each electrode of the adjacent first electrode group and second electrode group by electrostatic induction. Since it is charged to the opposite polarity and alternately charged positively and negatively, the number of electrical connections is reduced, the distance between the electrodes is reduced, the voltage applied to the electrodes is reduced, and heat generation and corrosion of the electrodes are suppressed. It is possible to effectively use all the electrodes to efficiently generate hydrogen gas from the surface of the positively charged electrode and oxygen gas from the surface of the negatively charged electrode. Can be made compact, and it has excellent combustion gas generation efficiency, energy saving, and installation flexibility.
(3) The electrolytic solution filling portion of the spacer has an electrolytic reaction opening that faces the electrode, and one or more electrode catching portions that are formed in steps on the periphery of the electrolytic reaction opening and engage with the electrode. As a result, since almost the entire surface of each electrode is in contact with the electrolyte and faces the adjacent electrode, it is possible to generate oxygen gas and hydrogen gas by effectively using the area of the electrode, and to generate combustion gas Excellent in efficiency.
(4) The electrolytic solution filling portion of the spacer has one or more electrode claw portions that are formed in a step shape on the periphery of the electrolytic reaction opening and engage with the electrode. It can be held easily and reliably according to the position, and it is excellent in assembling workability, and the outer periphery of the electrode is surrounded by spacers so that adjacent spacers are closely adhered to each other without any gaps. Can be maintained, and the electrolysis reliability is excellent.
(5) Since the electrolytic solution filling portion of the spacer has a combustion gas recovery opening extending above the electrolytic reaction opening, the combustion gas generated in the electrolytic reaction opening is converted into the combustion gas recovery opening. It is possible to collect and collect reliably from the combustion gas discharge part, and the combustion gas recovery efficiency is excellent.

Here, as the electrolyte of the electrolytic solution, one or more of acidic substances, alkaline substances, metal salts, and salts can be used.
As the electrode, a metal such as stainless steel, nickel, chromium, gold, platinum, titanium, and tantalum or a conductive base material such as carbon can be used. In addition, a conductive base material such as copper or brass whose surface is covered with platinum can be used. In particular, an insoluble electrode formed by electrodepositing platinum on the surface of titanium is preferably used. . By using an insoluble electrode, no sludge is generated from the electrode, maintenance of the electrolyte is easy, long life is excellent, it can be used at a high current density, and combustion gas generation efficiency is excellent.
As the shape of the electrode, various known ones such as a plate shape, a rod shape, a sheet shape, a thin film shape, and a net shape can be used.

  The spacer is not particularly limited as long as it has insulating properties (non-conductive), but a spacer formed of a synthetic rubber such as silicon rubber or a synthetic resin such as fluororesin, polypropylene, or vinyl chloride resin is preferably used. Depending on the type of electrolyte (electrolyte) and driving conditions, by selecting materials with acid resistance, alkali resistance, and heat resistance, durability can be improved and it can be used for a long time, saving resources Excellent. The shape of the spacer can be selected as appropriate, and is formed so as to face the entire surface of the electrode. As the spacer facing the entire surface of the electrode, a spacer formed in a frame shape having an opening serving as an electrolyte filling portion in the center is suitably used. By forming the spacer thicker than the electrode and forming a recess or an electrode claw portion that matches the outer shape of the electrode with a step (depth) equal to or greater than the thickness of the electrode on the periphery of the opening, The outer periphery of the electrode can be surrounded, and the portions other than the terminal portion of the electrode are not exposed to the outside of the spacer, and the adjacent spacers can be closely adhered to each other without a gap. Therefore, it is possible to prevent leakage of the electrolyte by forming a water-tight electrolytic cell simply by closing the openings of the spacers on the outermost layers, and it is not necessary to prepare a separate electrolytic cell, which is excellent in compactness.

3n electrodes (where n is a natural number equal to or greater than 3) are formed by arranging one electrode of the float electrode group on each side of the electrode of the first electrode group, and two electrodes. The electrodes of the float electrode group are arranged one by one on both sides of the electrodes of the group, and are arranged in such a manner that a set of three is arranged alternately. Accordingly, when a voltage having a reverse polarity is applied to the electrodes of the first electrode group and the second electrode group, the electrodes of the float electrode group facing each electrode of the first electrode group are electrostatically induced to the first electrode group. Charging the electrodes of the float electrode group opposite to the electrodes of the second electrode group to the opposite polarity to the voltages applied to the electrodes of the second electrode group. Can do.
The voltage applied to the electrodes of the first electrode group and the second electrode group is a direct current, but a direct current pulse power supply is preferably used as the power supply. Note that when hydrogen molecules or oxygen molecules adhere to the surface of the electrode, the current is temporarily interrupted, and the current flows when the hydrogen molecules or oxygen molecules are peeled off. Therefore, it is not always necessary to use a DC pulse.

Here, by forming the opening for electrolytic reaction to be the same size as or slightly larger than the outer shape of the electrode, the entire surface of the electrode can be brought into contact with the electrolytic solution, and the area of the electrode can be used effectively, and combustion gas generation is prevented. Excellent efficiency.
The combustion gas recovery opening is connected to the upper end side of the electrolytic reaction opening, and a triangular or trapezoidal shape whose width narrows upward is preferably used. This is because the combustion gas generated in the electrolytic reaction opening is collected at the upper end of the combustion gas recovery opening and efficiently recovered. In particular, when the width of the lower end of the combustion gas recovery opening is formed to be equal to the width of the upper end of the electrolytic reaction opening, the combustion gas generated from the entire electrode is reliably recovered without leakage. It can be collected at the opening for use and is excellent in the efficiency of recovery of the combustion gas.

The combustion gas discharge part 7 is not clogged with the electrolytic solution, and the combustion gas can be reliably discharged from the combustion gas discharge part 7, and the supply stability of the combustion gas is excellent. Thereby, when the combustion gas generator 1 is mounted on an automobile or the like, the combustion gas can be stably supplied even if the vehicle body (electrolyzer 2) is inclined due to the automobile or the like traveling on a slope. Excellent reliability.

In the present embodiment, by forming a part (both sides and lower side) of the electrolytic reaction opening 5a slightly larger than the outer shape of the electrodes 3a, 3b, 3c, the electrode receiving nail of the electrolyte filling portion 5 is formed. When the electrodes 3a, 3b, 3c and the spacer 4 are stacked by engaging the four corners of the electrodes 3a, 3b, 3c with the part 5c, the electrolyte solution flowing part 5d is formed on the outer periphery of the electrodes 3a, 3b, 3c. I made it. As a result, the electrolyte solution filling parts 5 of the adjacent spacers 4 communicate with each other through the combustion gas recovery opening 5b and the electrolyte solution circulation part 5d, and the electrolyte solution circulation property and the filling property are excellent.
The shape of the spacer 4 is not limited to this, and can be selected as appropriate.

Next, the operation principle of the combustion gas generator in Embodiment 1 will be described.
FIG. 6 is a schematic front view of an essential part showing the operation principle of the combustion gas generator in the first embodiment.
In FIG. 6, reference numeral 15 denotes a power supply unit of the combustion gas generator 1 that is electrically connected to the electrode 3b of the first electrode group 3B and the electrode 3c of the second electrode group 3C.
In FIG. 6, for convenience of explanation, it is assumed that the spacer 4 is omitted and the periphery of the electrodes 3a, 3b, 3c is filled with the electrolytic solution.
The electrode 3a of the float electrode group 3A that is not applied with voltage or grounded (3i-2) and (3i) th counted from one end is provided (where i = 1 to n is a natural number). Then, since n = 3, i = 1 to 3, and the first, third, fourth, sixth, seventh, and ninth are the electrodes 3a of the float electrode group 3A.
In addition, an electrode 3b of the first electrode group 3B to which a positive voltage is applied (2 + 6 (j−1)) th from one end is provided (provided that j = 1 to n1, n1 is 2 or more) Since the total number of the electrodes 3a, 3b, 3c is 3n = 9, n1 = 2, j = 1-2, and the second and eighth are the electrodes 3b of the first electrode group 3B.
Also, the electrode 3c of the second electrode group 3C to which a negative voltage having a polarity opposite to the voltage applied to the electrode 3b of the first electrode group 3B is applied (5 + 6 (k−1)) th from one end. Since the total number of electrodes 3a, 3b, and 3c is 3n = 9 (where k = 1 to n2, n2 is a natural number of 1 or more), n2 = 1, k = 1, and 5 The second is the electrode 3c of the second electrode group 3C.

In FIG. 6, nine electrodes 3a, 3b, and 3c are formed as a set of three by arranging the electrodes 3a of the float electrode group 3A one by one on both sides of the electrodes 3b of the first electrode group 3B. The electrodes 3a of the float electrode group 3A are arranged one by one on both sides of the electrode 3c of the second electrode group 3C, and a set of three sheets is arranged so that three sets are arranged alternately. Thus, when a positive voltage is applied to the electrode 3b of the first electrode group 3B and a negative voltage is applied to the electrode 3c of the second electrode group 3C, both sides of each electrode 3b of the first electrode group 3B are electrostatically induced. The electrodes 3a of the float electrode group 3A arranged on the negative electrode are negatively charged with the opposite polarity to the positive voltage applied to the electrodes 3b of the first electrode group 3B, and arranged on both sides of the electrodes 3c of the second electrode group 3C. The electrode 3a of the float electrode group 3A thus formed can be positively charged with a reverse polarity to the negative voltage applied to the electrode 3c of the second electrode group 3C.
As a result, all nine electrodes 3a, 3b, 3c are alternately charged negatively and positively, and hydrogen gas or oxygen gas can be generated from each electrode 3a, 3b, 3c.
In the present embodiment, the case of n = 3 (n1 = 2, n2 = 1) has been described. However, the electrodes 3a, 3b, and 3c can be arranged according to the above relationship according to the increase of n.

The generated combustion gas moves from the electrolytic reaction opening 5a of the electrolyte filling portion 5 to the combustion gas recovery opening 5b and accumulates, passes through the combustion gas discharge portions 7 of the left and right sandwiching portions 2a, and is stored in the electrolyte tank 12. Collected at the top of the. And it passes through the connecting pipe 14a and the collecting pipe 14b of the combustion gas discharge pipe 14 connected to the electrolyte injection section 13 of the electrolyte tank 12, and is stored in a larger tank or supplied to an engine such as an automobile and other combustion engines. Have been used.
Although this combustion gas generator 1 can be mounted on an automobile, a ship, or the like, the electrolytic cell 2 can be made compact by reducing the thickness of the electrodes 3a, 3b, 3c and the spacer 4. Moreover, since the combustion gas discharge part 7 and the electrolyte solution tank 12 are provided in two places on the left and right of the electrolytic cell 2, the electrolytic cell 2 is inclined in the longitudinal direction when an automobile or the like travels on a slope, Even if the combustion gas discharge part 7 is blocked by the electrolyte, the combustion gas can be reliably discharged from the other combustion gas discharge part 7 and recovered in the electrolyte tank 12, and the recovery and supply of the combustion gas can be stabilized. Excellent in properties.

As described above, the combustion gas generator in Embodiment 1 has the following effects.

Since it has the 2nd electrode group (however, k = 1-n2 and n2 are 1 or more natural numbers) to which the voltage of the reverse polarity is applied to the voltage applied to the electrode of the 1st electrode group, the electrode of the 1st electrode group A positive voltage or a negative voltage is applied to the second electrode group, and a voltage having a polarity opposite to that of the first electrode group is applied to the electrodes of the second electrode group. Each electrode of the float electrode group disposed adjacent to each other is separated from each electrode of the adjacent first electrode group and second electrode group by electrostatic induction. Since it is charged to the opposite polarity and alternately charged positively and negatively, the number of electrical connections is reduced, the distance between the electrodes is reduced, the voltage applied to the electrodes is reduced, and heat generation and corrosion of the electrodes are suppressed. It is possible to effectively use all the electrodes to efficiently generate hydrogen gas from the surface of the positively charged electrode and oxygen gas from the surface of the negatively charged electrode.

Hereinafter, the present invention will be specifically described by way of examples. The present invention is not limited to these examples.
Example 1
The dimensions of the electrode were 150 mm in height and 75 mm in width, and an insoluble electrode in which platinum was electrodeposited on the surface of titanium was used. The total number of electrodes is 24 (four electrodes of the first electrode group are arranged at the 2, 8, 14, and 20th positions, and four electrodes of the second electrode group are arranged at the 5, 11, 17, and 23rd positions. The remainder is 16 electrodes of the float electrode group), and the distance between each electrode is 1 mm.
A solution obtained by adding 4 g of electrolyte to 2 L of tap water was used as an electrolytic solution, and a voltage of 12 V was applied between the electrodes of the first electrode group and the second electrode group.
At this time, current consumption and temperature change of the electrolyte were measured.

(Example 2)
The electrode dimensions are 150 mm in height and 150 mm in width, and an electrolyte solution in which 8 g of electrolyte is added to 4 L of tap water is used, and a voltage of 18 V is applied between the electrodes of the first electrode group and the second electrode group. Except that, the current between the electrodes and the temperature change of the electrolytic solution were measured in the same manner as in Example 1.

7 and 8 are diagrams showing measurement results of the current between the electrodes and the temperature change of the electrolytic solution in Example 1 and Example 2, respectively. 7 and 8, the horizontal axis represents time [H], the left vertical axis represents current consumption [A], and the right vertical axis represents electrolyte temperature [° C.].
According to FIG. 7, in Example 1, the current consumption was approximately constant at about 12 A for about 50 minutes from the start of operation, but then suddenly decreased within about 10 minutes, and thereafter 9 A. Stable in degree. In addition, the electrolyte temperature continues to increase rapidly while the consumption current is approximately 12 A, but when the consumption current begins to decrease, the temperature rises gradually and stabilizes at approximately 9 A. The temperature of the electrolytic solution was stable at about 60 ° C. and did not increase any more.
Although FIG. 7 shows only 5.5 hours after the start of operation, even if the operation is continued for 48 hours, no change is seen in the consumption current and the electrolyte temperature, and the operation is stable. We were able to.
Further, when the amount of hydrogen gas generated was measured every hour from the start of operation to the end of operation, it was confirmed that about 500 cc of hydrogen gas was continuously generated per minute.

According to FIG. 8, in Example 2, the current consumption was substantially constant at about 20 A for about 50 minutes from the start of operation, but then suddenly decreased within about 10 minutes, and thereafter 15 A. Stable in degree. Further, the electrolyte temperature rapidly increased for about 30 minutes from the start of operation, but thereafter, the temperature increase gradually decreased, stabilized at about 42 ° C., and did not increase any more.
Further, when the amount of hydrogen gas generated was measured every hour from the start of operation to the end of operation, it was confirmed that about 1000 cc of hydrogen gas was continuously generated per minute.
In Example 2, since the electrode twice as large as that in Example 1 was used, almost twice as much hydrogen gas was generated, but the current consumption was suppressed to about 1.7 times, and the calorific value due to the temperature rise of the electrolyte solution Was also suppressed to about 1.3 (the amount of increase in temperature was 0.65 times, but the amount of heat was 1.3 times as the amount of electrolyte was doubled).

  When a positive electrode and a negative electrode of a power source are alternately connected to a plurality of electrodes as in the conventional case, the electrolyte temperature reaches nearly 100 ° C. and becomes a boiling state, water vapor is generated, and the electrode melts or undulates. However, in Examples 1 and 2, such a phenomenon did not occur, and it was confirmed that the temperature rise was kept low and stable operation could be realized.

  The present invention has a simple configuration, has a small number of parts, is easy to assemble and disassemble, is excellent in mass productivity and maintainability, and effectively uses the entire electrode as a combustion gas (oxygen-hydrogen mixed gas) containing oxygen gas and hydrogen gas. ) Can be efficiently generated, and the efficiency and reliability of electrolysis are excellent, and multiple electrodes can be easily and reliably held at predetermined intervals to prevent temperature rise and short-circuiting. Excellent in handling, durability, safety, reliability of operation, and stability, water that exists abundantly on the earth can be circulated and used effectively as an energy source to replace fossil fuels such as oil and coal. It is environmentally friendly, has a lower cost than hydrogen fuel, does not require expensive hydrogen tanks or hydrogen stations, has excellent environmental protection, and is an alternative fuel in various industries such as aviation, marine and automobile industries. Can be supplied, eliminating the resource shortage, it can contribute significantly to environmental protection.
