Description

HHO gas generator

The present invention relates to an HHO gas generation device that generates HHO gas, a fuel supply device for an internal combustion engine, a combustion device, an electrolyte for the HHO gas generation device, and an HHO gas generation method.

A mixed gas of hydrogen and oxygen in which hydrogen and oxygen are mixed at a mixing ratio of 2 to 1 is being studied for use in various fields as pollution-free energy. In particular, it has attracted attention as a fuel for internal combustion engines such as automobile engines. Such a mixed gas of hydrogen and oxygen is also called HHO gas or Brown gas. Hereinafter, in this specification, such a mixed gas is referred to as an HHO gas.

As an apparatus for generating HHO gas, an HHO gas generator using plasma and an HHO gas generator using electrolysis are known. However, an HHO gas generator using plasma is large in size and consumed. Since the electric power is extremely large, it is not suitable for use as a fuel generator for an internal combustion engine such as an automobile engine (hereinafter referred to as an automobile fuel generator). For this reason, an HHO gas generator using electrolysis is suitable for use as a fuel generator for automobiles. Various HHO gas generators utilizing electrolysis have been conventionally proposed (for example, see Patent Document 1 and Non-Patent Document 1).

Patent Document 1 describes a HHO gas generator using electrolysis. Non-Patent Document 1 describes an example in which an HHO gas generator utilizing electrolysis is incorporated in a vehicle and used as a fuel generator for a vehicle.

JP 2008-13821 A

As described above, various HHO gas generators utilizing electrolysis have been proposed, and it has been experimentally carried out that the HHO gas generator is mounted on a vehicle as a fuel generator for vehicles. It has not been put into practical use.

The reason why the HHO gas generator cannot be put into practical use as a fuel generator for automobiles is that various problems remain in using the HHO gas generator as a fuel generator for automobiles. For example, electrodes (anode plate and cathode plate) immersed in the electrolytic solution in the electrolytic bath are subject to deterioration due to electrolytic corrosion and become unusable in a short period of time, and control of the current flowing in the electrolytic solution is appropriate Therefore, there are many problems that need to be solved, such as the problem that an excessive current flows and the temperature rise of the electrolyte does not stop. For these reasons, the HHO gas generator has not been put into practical use as a fuel generator for automobiles.

Such a problem is not a problem that exists only when the HHO gas generator is put into practical use as a fuel generator for automobiles, but the HHO gas generator is used to generate fuel for internal combustion engines such as vehicles other than automobiles and ships. When it is put into practical use as an apparatus, it is also a problem that exists when it is put into practical use as a fuel generator for a combustion apparatus such as a household or commercial boiler, a thermal power plant, or a refuse incinerator.

Accordingly, the present invention has been made to solve the problems of the conventional HHO gas generator described above, and can be put to practical use as a fuel generator, a fuel supply device for an internal combustion engine, and a combustion device. And an HHO gas generating method for generating HHO gas, and an electrolyte for the HHO gas generating device for use in the HHO gas generating device.

[1] The HHO gas generator according to the present invention includes an electrolytic cell for storing an electrolytic solution containing water as a main component, a plurality of sets of electrodes each having an electrolytic corrosion resistance and each composed of an anode and a cathode, and the electrolysis A sealing lid that seals the upper end opening of the tank, and the electrolytic solution is electrolyzed by passing an electric current between the anode and the cathode of each of the plurality of sets of electrodes by using a power supply device to generate HHO. An electrolysis apparatus that generates gas and a current control apparatus that controls a current flowing between an anode and a cathode of each electrode to a predetermined current value for each electrode are provided.

In the HHO gas generator according to the present invention, the electrode has electric corrosion resistance. For this reason, according to the HHO gas generator of the present invention, it is possible to solve the problem of the conventional HHO gas generator, that is, "the problem that deterioration due to electric corrosion is severe and it cannot be used in a short period of time". it can.

In addition, since the HHO gas generator of the present invention has a plurality of sets of electrodes, a large amount of HHO gas can be stably generated. In addition, by having a plurality of sets of electrodes, the current value of the current flowing through each electrode may be different for each electrode, thereby causing a problem that the temperature of the characteristic electrode rises abnormally. In some cases. Therefore, the present invention includes a current control device that controls the current flowing between the anode and the cathode of each electrode to a predetermined current value for each electrode. By having such a current control device, the current flowing between the anode and cathode in each electrode can be set to a predetermined current value for each case electrode, and the current flows between the anode and cathode in each electrode. The current can be made uniform with an appropriate current value. As a result, the other problem of the conventional HHO gas generator, that is, “the problem that current more than necessary flows and the temperature rise of the electrolyte does not stop,” can be solved.

Thus, according to the HHO gas generator of the present invention, the above two problems of the conventional HHO gas generator can be solved. For this reason, the HHO gas generator of the present invention will be put to practical use as a fuel generator for combustion engines such as internal combustion engines such as vehicles and ships, as well as household and commercial boilers, thermal power plants, and garbage incinerators. Is possible.

[2] In the HHO gas generator of the present invention, the current control device has a plurality of current control units corresponding to the electrodes, and the current control units of the plurality of current control units respectively correspond to the current control units. It is preferable to control the current flowing between the anode and the cathode of the electrode to the predetermined current value.

Thus, by having a plurality of current control units corresponding to each electrode, the current flowing between the anode plate and the cathode in each electrode can be set to a predetermined current value for each electrode.

[3] The HHO gas generator of the present invention preferably further includes a temperature control device for controlling the temperature of the electrolytic solution so that the temperature of the electrolytic solution does not exceed a preset temperature.

By providing such a temperature control device, it is possible to control the temperature of the electrolytic solution itself in addition to suppressing an abnormal increase in the temperature of the electrolytic solution due to current control. That is, in the HHO gas generator of the present invention, double measures are taken in order to prevent the temperature of the electrolyte from rising abnormally. Thus, according to the HHO gas generator of the present invention, it is possible to reliably prevent the temperature of the electrolyte from rising abnormally. In addition, since the temperature of the electrolytic solution can be detected by measuring the temperature of the electrolytic cell, “controlling the temperature of the electrolytic solution so that the temperature of the electrolytic solution does not exceed the set temperature” It also includes measuring the temperature of the electrolytic cell and performing temperature control using the measured temperature of the electrolytic cell as the temperature of the electrolytic solution.

[4] In the HHO gas generator of the present invention, the temperature control device turns off the energization of the electrodes when the temperature of the electrolytic solution rises to a first set temperature, and turns off the energization and turns off the energization. It is preferable to operate so that energization of each electrode is turned on when the temperature of the electrolytic solution drops to a second set temperature lower than the first set temperature.

With such a configuration, it is possible to reliably prevent the temperature of the electrolytic solution from becoming higher than the first set temperature. Thereby, if the upper limit temperature at which the temperature of the electrolytic solution does not become abnormally high is set as the first set temperature, it is possible to prevent the electrolytic solution from becoming abnormally high for some reason. Further, when the temperature of the electrolytic solution drops to a second set temperature lower than the first set temperature, the electrolysis can be started again by turning on the energization of each electrode.

[5] In the HHO gas generator of the present invention, it is preferable that the first set temperature is in a range of 65 ° C. to 75 ° C. and the second set temperature is in a range of 40 ° C. to 60 ° C.

Thus, since the first set temperature is in the range of 65 ° C. to 75 ° C., it is possible to reliably prevent the temperature of the electrolytic solution from becoming higher than 65 ° C. to 75 ° C. In addition, since the second set temperature is set to 45 ° C. to 55 ° C., the current supply to each electrode can be restored if the temperature drops slightly after the power supply to each electrode is cut off. It will be possible to resume as soon as possible.

[6] In the HHO gas generator of the present invention, a reference temperature is set for the temperature of the electrolytic solution, and an allowable range for the reference temperature is set. The temperature control device is configured such that the temperature of the electrolytic solution is the allowable temperature. It is preferable to operate so as to control the current value so as to be held in a range.

This simply turns on the energization of each electrode so that the energization to each electrode is cut off when the temperature of the electrolyte reaches the first set temperature and the energization to each electrode is restored when the temperature reaches the second temperature. It is not to control off / off, but to control the current flowing between the anode plate and the cathode plate in each electrode based on the temperature detected by the temperature sensor. Specifically, the current is controlled so that the temperature of the electrolytic solution is maintained within a predetermined allowable range with the set reference temperature as a boundary. By performing such control, the electrolytic solution is controlled. Can always be maintained within an appropriate temperature range. Such control can be realized by using, for example, PID control or digital control corresponding to PID control.

It was confirmed from the results of various experiments conducted by the inventor of the present invention that an electrode having excellent electric corrosion resistance can be obtained by configuring the anode as described above. Thereby, it can suppress that an anode deteriorates by electric corrosion, and it can be set as the electrode which can endure long-term use. Thereby, the durability of the HHO gas generator of the present invention can be improved. According to the experiments conducted by the inventors of the present invention, good results can be obtained even when the anode is formed by applying a carbon film on a titanium material by a coating method, a plating method or a welding method. It could be confirmed.

[8] In the HHO gas generator of the present invention, it is preferable that the cathode has a platinum film formed on a titanium material by a coating method, a plating method or a welding method.

It has been found from the results of various experiments conducted by the inventors of the present invention that an electrode having excellent electric corrosion resistance is obtained when the cathode has such a configuration. Thereby, it can suppress that a cathode deteriorates by electric corrosion, and it can be set as the electrode which can endure long-term use. Thereby, the durability of the HHO gas generator of the present invention can be improved. In addition, according to the experiments conducted by the inventors of the present inventor, as the cathode, good results can be obtained even when a gold film is formed on a titanium material by a coating method, a plating method or a welding method, It was also confirmed that good results were obtained even when a stainless material was used as the cathode.

¡Efficient electrolysis can be achieved with a simple configuration by configuring the anode and cathode of each electrode in this way.

[10] In the HHO gas generator of the present invention, the predetermined current value is within a range of 0.007 ampere to 0.06 ampere per 1 cm ^{2 with} respect to the area of the cathode plate facing the anode plate. Preferably there is.

By setting the current flowing between the anode plate and the cathode plate in each electrode in this way, stable electrolysis can be performed while the temperature of the electrolytic solution is appropriately maintained. The current flowing between the anode plate and the cathode plate in each electrode varies somewhat depending on the material of the electrode, etc., but is 0.007 ampere to 0.005 ampere per cm ^{2 with} respect to the area of the cathode plate facing the anode plate. It is preferable to use 06 amperes. Here, 0.007 ampere to 0.06 ampere per 1 cm ² means that, for example, each of the anode plate and the cathode plate in each electrode has a size of 12 cm × 12 cm, and one anode plate is 2 In the case of having a structure arranged so as to be sandwiched between ^two cathode plates, the area of the cathode plate facing the anode plate is 288 cm ^2, and therefore, between the anode plate and the cathode plate in the electrode. It is preferable to set the current to flow within a range of about 2 amperes to about 18 amperes.

[11] In the HHO gas generator of the present invention, the electrolytic cell is provided with a partition plate between two adjacent electrodes of the plurality of sets of electrodes, and the partition plate has a lower end side which is It is preferable to be installed in a state of being in close contact with the bottom surface of the electrolytic cell and having a side edge in close contact with the side surface of the electrolytic cell.

By providing such a partition plate, a plurality of partition rooms are formed in the electrolytic cell of the electrolysis apparatus, and each electrode is present in each partition room for each individual electrode. Even when tilted, since a certain amount of electrolyte is held in each partition room, it is possible to prevent a problem that a specific electrode is exposed from the electrolyte.

[12] In the HHO gas generator of the present invention, the height of the partition plate is such that the upper end side of the partition plate is higher than the upper end side of the electrode. It is preferable that the upper end side has a notch that allows the electrolyte solution to flow to the adjacent electrode side, and has a height that allows the position to be at or above the appropriate level.

By setting the height of the partition plate to be equal to or higher than the appropriate level of the electrolytic solution storage amount, even when the electrolyzer is slightly inclined, the effect that a certain amount of electrolytic solution is retained in each partition room can be further enhanced. it can. In addition, the upper end side is formed with a notch that allows the electrolyte solution to flow to the adjacent electrode side, so that the electrolyte solution is injected to an appropriate level of the electrolyte solution storage amount, In the case where the electrolytic cell is horizontal, the level of the electrolytic solution can be adjusted to an appropriate level throughout the electrolytic cell.

[13] The HHO gas generator of the present invention preferably further includes an electrolyte replenishment mechanism that can automatically replenish the electrolyte when the electrolyte stored in the electrolytic cell decreases.

By providing such an electrolytic solution replenishment mechanism, when the electrolytic solution in the electrolytic cell is reduced, the electrolytic solution is automatically dropped and replenished, so that the electrolytic solution in the electrolytic cell can always be maintained at an appropriate level. it can. This eliminates the need for the user of the HHO gas generator of the present invention to worry about the amount of electrolyte in the electrolytic cell.

By mixing the HHO gas with air at such a ratio, the internal combustion engine can be operated with higher combustion efficiency, thereby improving fuel efficiency and reducing harmful exhaust gas emissions.

[16] In the fuel supply device for an internal combustion engine of the present invention, the internal combustion engine is preferably a vehicle engine.

As described above, when the HHO gas generator according to any one of [1] to [13] is used as an auxiliary fuel generator for a vehicle engine, the HHO gas generated from the HHO gas generator is supplied to the engine. By supplying the fuel intake (for example, an intake manifold), the HHO gas is combusted with fuel such as atomized gasoline in the engine. Thus, by burning the HHO gas together with the atomized fuel such as gasoline, the fuel efficiency can be improved and the amount of harmful exhaust gas discharged can be reduced.

[17] In the fuel supply device for an internal combustion engine of the present invention, the power supply device is preferably a storage battery mounted on the vehicle.

Thus, since the storage battery (battery) originally mounted on a vehicle such as an automobile can be used as the power supply device of the HHO gas generation device of the present invention, a power supply device dedicated to the HHO gas generation device becomes unnecessary, and the HHO When the gas generator is mounted on an automobile, it can be mounted at low cost, and the installation space can be kept small.

In the following embodiment, a case where the HOO gas generation device of the present invention is used as an auxiliary fuel generation device in an internal combustion engine (also referred to as an engine) for automobiles will be described as an example.

[Embodiment 1]
FIG. 1 is a diagram illustrating a configuration of an HHO gas generation device 10 according to the first embodiment. FIG. 2 is a diagram illustrating an internal configuration of an electrolysis device 100 used in the HHO gas generation device 10 according to the first embodiment. . 2 is a cross-sectional view taken along line yy in FIG.
FIG. 3 is a diagram showing a set of electrodes taken out.
FIG. 4 is a view for explaining the partition plate 180A.
FIG. 5 is a view for explaining the case where the electrolytic cell 110 is tilted. 2 to 5, the same components as those in FIG. 1 are denoted by the same reference numerals.

As shown in FIG. 1, the HHO gas generator 10 according to the first embodiment is configured so that the current flowing between the electrolysis device 100 and the anode and the cathode in each electrode of the electrolysis device 100 has a predetermined current value. A current control device 200 that controls the power supply, and a power supply device 300 as a DC power supply. The anode of each electrode is connected to the positive (+) side terminal of the power source (each current control unit 210, 220, 230 in the current control device in the HHO gas generator 10 according to Embodiment 1). The cathode is an electrode connected to the negative (−) terminal of the power source.

The electrolysis apparatus 100 has an external configuration of an electrolytic cell 110 that stores an electrolytic solution 101 (see FIG. 2) containing water (pure water) as a main component, and a sealing lid that seals the upper end opening of the electrolytic cell 110. 120 and an anode side electrode terminal 161a for supplying power to each of a plurality of sets (three sets) of electrodes 130, 140, and 150 (see FIG. 2) each of which includes an anode and a cathode. 162a, 163a and cathode side electrode terminals 161b, 162b, 163b, an electrolyte solution supply port 171 when supplying the electrolyte solution 101 into the electrolytic cell 110, a cap 171a for opening and closing the electrolyte solution supply port 171, A pressure adjusting unit 172 that adjusts the pressure in the electrolytic cell 110 in response to a change in atmospheric pressure due to a difference in altitude and the like, and a HHO gas discharge nozzle that discharges HHO gas generated by electrolysis And a 73.

The anode side electrode terminals 161a, 162a, 163a, the cathode side electrode terminals 161b, 162b, 163b, the electrolyte solution supply port 171, the pressure adjusting unit 172, and the HHO gas discharge nozzle 173 are provided on the upper surface of the sealing lid 120, respectively. Yes.

The electrolytic cell 110 is made of transparent or translucent reinforced synthetic resin. The sealing lid 120 is made of a synthetic resin that is transparent or translucent and lower in strength than the electrolytic cell 110. Thus, the reason why the sealing lid 120 is made of a synthetic resin that is lower in strength than the electrolytic cell 110 is that the internal pressure of the electrolytic cell 110 becomes abnormally high for some reason and the electrolytic cell 110 bursts. This is because, when the case is assumed, if only the sealing lid 120 that is lower in strength than the electrolytic cell 110 is destroyed, the loss due to the destruction can be reduced. That is, if the entire electrolytic cell 110 including the sealing lid 120 is made of a reinforced synthetic resin, there is a risk that the rupture force will not escape and the destructive force may be increased, but the sealing lid 120 is stronger than the electrolytic cell 110. If the synthetic resin is extremely low, it is only necessary to break the sealing lid 120, and the loss due to breakage can be kept small.

Moreover, it is not essential that the electrolytic cell 110 and the sealing lid 120 are transparent or translucent. However, the electrolytic cell 110 and the sealing lid 120 may be transparent or translucent so that the storage amount of the electrolytic solution 101 can be easily confirmed from the outside. More preferred.

The pressure adjusting unit 172 adjusts the pressure in the electrolytic cell 110 in response to changes in atmospheric pressure, and maintains the pressure in the electrolytic cell 110 at an appropriate pressure. For example, in a place where the altitude is high and the atmospheric pressure is low, it operates so as to release the pressure in the electrolytic cell 110. Further, not only the difference in altitude, but also when the pressure in the electrolytic cell 110 becomes high for some reason, it operates so as to release the pressure in the electrolytic cell 110. Thereby, the pressure in the electrolytic cell 110 can be maintained at an appropriate pressure.

The current control device 200 includes three current control units 210, 220, and 230 corresponding to the electrodes 130, 140, and 150, respectively.
The positive (+) side terminal of the current control unit 210 is connected to the anode electrode terminal 161 a provided in the electrolysis apparatus 100, and the negative (−) side terminal of the current control unit 210 is provided in the electrolysis apparatus 100.

Connected to the negative electrode terminal 163b.

In FIG. 1, the current control units 210, 220, and 230 are shown as if they were individually provided, but the current control units 210, 220, and 230 are included in one case. It may be incorporated as a circuit configuration. Details of the electrodes 130, 140, 150 and the current control units 210, 220, 230 will be described later.

The anodes and cathodes in the electrodes 130, 140, and 150 are composed of one anode plate and two cathode plates. One anode plate and two cathode plates are centered on one anode plate. Thus, the two cathode plates are arranged so as to face the anode plate at a predetermined interval with respect to the one anode plate.

For example, taking the electrode 130 as an example, as shown in FIG. 2, the electrode 130 is composed of one anode plate 131 and two cathode plates 132 disposed so as to sandwich the anode plate 131. 133. Further, as shown in FIG. 2, the lower end side of the anode plate 131 and the lower end side of the cathode plates 132 and 133 are supported in a state in which movement is restricted by an electrode support member 134 made of an insulating member such as a synthetic resin.

Due to such a configuration, the anode plate 131 and the cathode plates 132 and 133 are held at appropriate positions in the electrolytic cell 110 while maintaining a proper interval between the electrodes.

The electrodes 140 and 150 have the same configuration as the electrode 130. In FIG. 2, the reference numerals of the constituent elements are omitted from the electrodes 140 and 150.

The electrodes 130, 140, and 150 will be described in more detail. Since the electrodes 130, 140, and 150 have the same configuration, the electrode 130 will be described in detail here with reference to FIG. The electrode 130 has electric corrosion resistance. In order to have electric corrosion resistance, the anode plate 131 uses a titanium material as a base material, and an iridium film is formed on the titanium material by a coating method, a plating method, or a welding method. On the other hand, the cathode plates 132 and 133 also use titanium as a base material, and a platinum film is formed on the titanium material by a coating method, a plating method, or a welding method.

When the anode plate 131 and the cathode plates 132 and 133 are configured as described above, an electrode having excellent electric corrosion resistance can be obtained. Thereby, it can suppress that the anode plate 131 and the cathode plates 132 and 133 deteriorate by electric corrosion, and it can be set as the electrode which can endure long-term use.

Further, as shown in FIG. 3, the anode plate 131 and the cathode plates 132 and 133 are arranged such that the two cathode plates 132 and 133 are spaced apart from the anode plate 131 by a certain distance from the anode plate 131. It is arranged to face 131 in parallel. By arranging the anode plate 131 and the cathode plates 132 and 133 in this manner, efficient electrolysis can be achieved with a simple configuration. The distance d between the cathode plates 132 and 133 and the anode plate 131 is in the range of 0.2 mm to 15 mm in the embodiment, but is preferably as narrow as possible.

Further, as shown in FIG. 3, the anode plate 131 has an anode plate hanging bracket 135 attached to the upper end thereof, and is electrically connected to the anode side electrode terminal 161a via the anode plate hanging bracket 135. .

The side electrode terminal 161b is electrically connected. In addition, the cathode plate hanging metal fittings 136 and 137 are electrically connected to the cathode side electrode terminal 161b in a state where they are gathered together.
Although the electrode 130 has been described here, the electrode 140 and the electrode 150 are also made of the same material as the electrode 130 and have the same configuration as the electrode 130.

Next, the partition plates 180A and 180B will be described with reference to FIGS. The partition plates 180A and 180B are formed of a plate-like member made of synthetic resin or the like, and partition between two adjacent electrodes among the electrodes 130, 140, and 150, as shown in FIG.

By providing such partition plates 180A and 180B, three partition chambers R1, R2, and R3 are formed inside the electrolytic cell 110 (see FIG. 2), and the electrode 130 exists in the partition chamber R1. The electrode 140 exists in the partition room R2, and the electrode 150 exists in the partition room R3.

Such partition plates 180A and 180B will be described in more detail with reference to FIG. Since the partition plates 180A and 180B have the same configuration, the partition plate 180A will be described as an example here.

The partition plate 180 </ b> A is installed in the electrolytic cell 110 with a lower end side 184 in close contact with the inner bottom surface of the electrolytic cell 110 and side end sides 182 and 183 in close contact with the internal side surface of the electrolytic cell 110. Further, in the partition plate 180A, notches 185 and 186 are formed on the upper end side 181 of the partition plate 180A so that the electrolytes present in the partition rooms R1, R2, and R3 can flow through each other. In the HHO gas generator 10 according to the first embodiment, notches 185 and 186 are formed at two corners formed by the upper end side 181 and the side end sides 182 and 183, respectively.

The notches 185 and 186 are formed by cutting the partition plate 180A by a predetermined length in the horizontal direction (direction along the y axis) and the vertical direction (direction along the z axis). Yes, the edges of the notches 185 and 186 after cutting are L-shaped.

By the way, the dimension from the lower end side 184 to the upper end side 181 of the partition plate 180A (referred to as the height h1 of the partition plate) is such that when the partition plate 180A is installed in the electrolytic cell 110, the upper end side 181 of the partition plate 180A. It is preferable to set the height so as to be at a level that is the same as or slightly higher than the appropriate level L1 (see FIG. 2) of the storage amount of the electrolytic solution 101. The height h2 from the lower end side 184 of the partition plate 180A to the lower end portion P1 of the notches 185 and 186 is such that the lower end portion P1 of the notches 185 and 186 is when the partition plate 180A is installed in the electrolytic cell. It is preferable to set the height so as to be slightly below the appropriate level L1 of the storage amount of the electrolytic solution 101.

The cutout portions 185 and 186 are formed in the same manner on the partition plate 180B and the partition plate 180A. If the partition plates 180A and 180B have such cutout portions 185 and 186, the amount of the electrolyte 101 stored in the electrolytic cell 110 is equal to or higher than the lower end portion P1 of the cutout portions 185 and 186, When the electrolytic cell 110 is horizontal, the electrolytic solution 101 in each of the partition rooms R1, R2, and R3 can be all leveled at the same level. Further, even when the electrolytic cell 110 is slightly inclined, the electrolytic solution 101 is leveled for each of the partition rooms R1, R2, and R3, and a problem that a specific electrode is exposed from the liquid surface of the electrolytic solution 101 is prevented. be able to.

For example, as shown in FIG. 5, when the electrolytic cell 110 is tilted by a predetermined angle θ clockwise with respect to the z axis with the y axis as the rotation axis, the electrolytic solution 101 in each of the partition rooms R1, R2, R3 is In each of the partition rooms R1, R2, R3, it becomes horizontal. For this reason, the electrolyte solution 101 in the partition rooms R1, R2, and R3 is maintained at a constant amount, and the upper end portions of the electrodes 130, 140, and 150 can be prevented from being exposed from the electrolyte solution 101. . As shown in FIG. 5, when the amount of the electrolytic solution 101 is sufficiently stored, the electrolytic solution in the partition room R1 flows to the partition rooms R2 and R3, and the electrolytic solution in the partition room R2 is also partitioned. As shown in FIG. 5, when the amount of the electrolytic solution is small, the electrolytic solution 101 in the partition chambers R1, R2, and R3 flows through the partition plates 180A and 180B. Be blocked. In FIG. 5, the reference numerals of the constituent elements are not shown in some cases.

Assuming that the HHO gas generation device 10 according to the first embodiment is mounted on an automobile, the automobile hardly tilts so much in a normal traveling state, and thus such partition plates 180A and 180B are provided. Accordingly, it is possible to prevent a problem that the upper end portion of the specific electrode is exposed from the electrolytic solution 101.

In addition, even when the electrolytic cell 110 is tilted by a predetermined angle clockwise or counterclockwise with respect to the z axis with the x axis as a rotation axis, the electrolytic cells existing in the partition rooms R1, R2, and R3 in the electrolytic cell 110 are present. Since the liquid 101 circulates between the partition chambers R1, R2, and R3 due to the presence of the cutout portions 215 and 216, it is possible to eliminate the uneven storage amount of the electrolyte solution 101 in each of the partition chambers R1, R2, and R3.

By providing such partition plates 180A and 180B, even if the electrolytic cell 110 is slightly inclined, the electrolyte solution 101 in the partition chambers R1, R2, and R3 can maintain a certain amount for each partition chamber. It is possible to prevent the upper end portion of the electrode from being exposed from the electrolytic solution 101. In particular, when the HHO gas generator according to the first embodiment is mounted on an automobile, the automobile is inevitably tilted somewhat during traveling, and therefore the partition plates 180A. It is effective to provide 180B.

Next, the electrolytic solution 101 will be described. The electrolytic solution 101 has water (distilled water) as a main component. However, in the HHO gas generator 10 according to Embodiment 1, a sodium carbonate aqueous solution or water (in which a predetermined amount of sodium carbonate is dissolved in water (distilled water)) or water ( An aqueous sodium hydrogen carbonate solution in which a predetermined amount of sodium hydrogen carbonate is dissolved in distilled water) is used. The weight ratio of sodium carbonate or sodium bicarbonate to water is preferably set to about 0.1% to 20%, more preferably about 5%.

Electrolysis can be accelerated | stimulated because the electrolyte solution 101 is comprised with such a component. There are other substances that promote electrolysis, but sodium carbonate or sodium bicarbonate is advantageous in that it is inexpensive and highly safe and easily available.

Moreover, it is preferable that the electrolytic solution 101 is stored in the electrolytic cell 110 in a state where the carbonic acid content is removed. This is because if carbonic acid is present, the carbonic acid may contaminate the electrodes 130.140 and 150 and adversely affect the electrodes. The state in which the carbonic acid content is removed can be obtained by heating a sodium carbonate aqueous solution or a sodium hydrogen carbonate aqueous solution, respectively.

In addition, when the HHO gas generator 10 according to Embodiment 1 can be used in a cold region, it is preferable to mix a predetermined amount of, for example, ethylene glycol or the like as an antifreezing agent into the electrolytic solution 101. The amount of the antifreezing agent is appropriately set according to the minimum temperature in each region.

Next, the current control units 210, 220, and 230 will be described. As shown in FIG. 1, the current control units 210, 220, and 230 are provided corresponding to the electrodes 130, 140, and 150. As the power supply device 300, for example, an automobile storage battery (12 volts or 24 The electric power from each of the electrodes 130, 140, and 150 is controlled so that the current flowing between the anode plate and the cathode plate becomes a predetermined current value for each electrode.

At this time, the current flowing between the anode plate and the cathode plate in each of the electrodes 130, 140, and 150 is set to an optimal current value as appropriate according to the material and area of the electrode. According to experiments, when an anode plate having an iridium film formed on titanium and a cathode plate having a platinum film formed on titanium are used, the electrodes 130, 140, and 150 are used. It is preferable to set within a range of 0.007 ampere to 0.06 ampere per 1 cm ^{2 with} respect to the area of the cathode plate facing the anode plate, and set to about 0.02 ampere to 0.03 ampere per 1 cm ^2. Then, a better result is obtained.

For example, as shown in FIGS. 2 and 3, when a single anode plate is sandwiched between two cathode plates, even one anode plate can be used on both sides. If the vertical and horizontal lengths of the cathode plate are 12 cm, the area of the cathode plate facing the anode plate is 12 cm × 12 cm × 2 = 288 cm ^{2 in} this case. Therefore, in the 1 cm ² per 0.007 amperes is 288Cm ^2, becomes 0.007 × 288 ≒ 2.0 amperes in 1 cm ² per 0.06 amps is 288cm ^2, 0.06 × 288 ≒ 17.3 Become an ampere. Therefore, in this case, the current flowing between the anode and the cathode in each electrode 130, 140, 150 is preferably in the range of about 2.0 amperes to about 18 amperes, more preferably about 5 amperes to It is about 9 amps.

According to the experiment, when the current is less than 2 amperes, the electrolysis is insufficient, and when the current exceeds 18 amperes, the electrolysis becomes excessive and the temperature of the electrolyte solution may become too high. It was confirmed that there was. In addition, if the area of an electrode is enlarged, a bigger electric current can be sent. In addition, the above current value is an example, and the optimum value varies somewhat depending on the electrode material, etc., but the current value should generally be set in the above range (about 2 amperes to about 18 amperes). Is preferred.

By the way, the current control units 210, 220, and 230 perform control such that the current flowing between the anode plate and the cathode plate in the corresponding electrode is set to the above-described current value. Voltage control is also performed on (for example, 12 volts or 24 volts), and in this case, the voltage output from each current control unit 210, 220, 230 is controlled to be 2 to 4 volts.

As described above, in the HHO gas generation device 10 according to the embodiment, the current control units 210, 220, and 230 can be said to be power sources for each electrode that are provided corresponding to the electrodes 130, 140, and 150. . For this reason, even if the entire power supply device 300 is a storage battery for automobiles (12 volts or 24 volts), for each electrode, a voltage value of about 2 to 4 volts for each electrode is about 6 amps. Current can flow.

Since the HHO gas generator 10 according to the embodiment includes such current control units 210, 220, and 230, the current that flows between the anode plate and the cathode plate in each electrode 130, 140, and 150 is made uniform. Can do. Since the current flowing between the anode plate and the cathode plate in each electrode 130, 140, 150 can be made uniform, the heat generated in each electrode 130, 140, 150 can be made uniform, and the heat between the electrodes can be made. Can be reduced.

Here, assuming that a storage battery of an automobile is a power supply device, a plurality of (in this case, three) electrodes 130, 140, 150 are connected in parallel to the power supply device, and three electrodes 130, 140, 150 are connected from the power supply device. If the current is applied to 150, current deviation occurs in the three electrodes, thereby causing a deviation in the magnitude of heat generation in each electrode, resulting in locally high heat. Inconvenience will occur.

On the other hand, like the HHO gas generation device 10 according to the first embodiment, a predetermined current value (for example, 6 amperes) is supplied from the corresponding current control units 210, 220, and 230 to the electrodes 130, 140, and 150, respectively. These problems can be eliminated by adopting a configuration that allows the current to flow. Accordingly, the generation of HHO gas can be stabilized, and the HHO gas can be generated efficiently. In addition, in the HHO gas generator 10 which concerns on Embodiment 1, it has confirmed by experiment that the temperature in each electrode 130,140,150 can be suppressed to about room temperature.

FIG. 6 is a flowchart for explaining the HHO gas generation method according to the first embodiment. FIG. 6 shows a process until HHO gas is generated.

As shown in FIG. 6, each step of the HHO gas generation method according to Embodiment 1 includes a sodium carbonate aqueous solution or hydrogen carbonate in which the weight ratio of sodium carbonate or sodium hydrogen carbonate to water is in the range of 0.1% to 20%. A step of injecting an aqueous sodium solution into the electrolytic cell 110 as the electrolytic solution 101 (step S1), and a current control device 200 controlling the current flowing between the anode plate and the cathode plate in each electrode 130, 140, 150, A step (step S2) of generating an HHO gas by electrolyzing the electrolytic solution 101 by passing an electric current between the anode plate and the cathode plate of the electrodes 130, 140, 150 is performed in this order.

FIG. 7 is a view for explaining a fuel supply device 500 for an internal combustion engine including the HHO gas generation device 10 according to the first embodiment. It is assumed that the internal combustion engine is an automobile engine. In FIG. 7, among the components of the HHO gas generator 10, the current control units 210, 220, 230 and the power supply device 300 are not shown, and only the electrolyzer 100 is shown. Further, the electrolysis apparatus 100 shown in FIG. 7 is a view of the electrolysis apparatus 100 in FIG. 1 as viewed in the direction of the arrow a. In FIG. 7, the same components as those in FIG. ing. Further, illustration of electrodes and the like provided in the electrolytic cell 110 is also omitted.

As shown in FIG. 7, the fuel supply device 500 for an internal combustion engine includes an air cleaner 510 originally present in a general automobile, a carburetor or an electronically controlled fuel injection device (herein described as a carburetor 520), and In addition to the intake manifold 530, the HHO gas generator 10 is incorporated.

The carburetor 520 atomizes the fuel (referred to as gasoline) and generates fuel (hereinafter referred to as air-mixed atomized gasoline) in which air is mixed with the atomized gasoline at a predetermined mixing ratio. The air-mixed atomized gasoline is supplied to the intake manifold 530. The intake manifold 530 distributes the air-mixed atomized gasoline supplied from the carburetor 520 to each combustion chamber (not shown) of the engine. On the other hand, in the HHO gas generator 10, the HHO gas discharge nozzle 173 provided in the electrolyzer 100 is connected to an intake manifold 530 as a fuel intake port of an engine by an HHO gas supply pipe 540. The generated HHO gas is supplied to the intake manifold 530.

Since the fuel supply device 500 for the internal combustion engine has such a configuration, in the intake manifold 530, the HHO gas is mixed with the air-mixed atomized gasoline supplied from the carburetor 520, and the HHO gas is mixed with the air. Mixed atomized gasoline is distributed to each combustion chamber of the engine by the intake manifold.

In such a fuel supply device 500 for an internal combustion engine, a switch (not shown) for starting the HHO gas generation device 10 is interlocked with an ignition switch (not shown) of the automobile. Thus, when the ignition switch of the automobile is turned on and the engine is started, the HHO gas generator 10 is also started, and each electrode 130 of the electrolysis apparatus 100 is started from each current control unit 210, 220, 230 (see FIG. 1). , 140, 150 (see FIG. 2), and electrolysis occurs in the electrolysis apparatus 100. That is, while the engine is operating, electrolysis occurs in the electrolyzer 100 to generate HHO gas, and the generated HHO gas is supplied from the HHO gas discharge nozzle 173 to the intake manifold 530. ing.

In the fuel supply device 500 for an internal combustion engine, it is preferable to mix the volume of HHO gas with respect to the volume of air taken into the carburetor 520 at a ratio of 1/500 to 1 / 50,000. Preferably, the volume of the HHO gas is mixed at a ratio of 1/20000 to 1/40000 with respect to air. By mixing HHO gas with air at such a ratio, the engine can be operated with higher combustion efficiency, which can improve fuel efficiency and reduce harmful exhaust emissions. It was confirmed. In the experiment, better results were obtained when the volume of the HHO gas was mixed at a rate of 1/30000 with respect to the air.

In order to mix the HHO gas with the air at such a ratio, in FIG. 7, the HHO gas generated by the HHO gas generator 10 is supplied from the HHO gas discharge nozzle 173 to the intake manifold 530 through the HHO gas supply pipe 540. Although not shown in the supply path, this can be realized by providing an HHO gas supply amount control device such as a supply control valve.

Also, when such a fuel supply device 500 for an internal combustion engine is mounted on an automobile, it is preferable to set the ignition timing of the engine to be slightly earlier than usual. This is because if HHO gas with high combustion energy is mixed in atomized gasoline, the engine will operate more efficiently if it is ignited slightly earlier than the normal ignition timing. Because it can be created.

In the case of an automobile equipped with such a fuel supply device 500 for an internal combustion engine, the HHO gas generator 10 is installed in the automobile not equipped with the fuel supply device 500 for the internal combustion engine, that is, the fuel supply device for the internal combustion engine. It has been found that there are various advantages compared to a car that does not have one. This will be described below.

Here, an automobile with a displacement of 1300 cc (referred to as a first measurement vehicle) and an 1800 cc automobile (referred to as a second measurement vehicle) in a certain automobile manufacturer (referred to as company A) and another automobile manufacturer (referred to as company A). The case where the HHO gas generator 10 is not used, and the case where the HHO gas generator 10 is provided using an automobile (referred to as a third measurement vehicle) having a displacement of 1000 cc. For both, the measurement results of fuel consumption and exhaust gas will be described.

Note that the three automobiles (first to third measurement vehicles) used in this experiment are automobiles equipped with a gasoline engine (referred to as gasoline cars). In the following, an automobile provided with the HHO gas generator 10 in the fuel supply device for the internal combustion engine will be referred to as “a vehicle not equipped with the HHO gas generator”, and the HHO gas generator 10 will be used as the fuel supply device for the internal combustion engine. An automobile equipped with the “HHO gas generator mounted automobile” will be described. In the case of “a vehicle equipped with a HHO gas generator”, it is natural that the HHO gas is supplied to the engine.

First, when using the first vehicle for measurement and running on an urban area and traveling long distances (cumulative total of 200 km or more) with an “HHO gas generator non-equipped vehicle”, the average fuel consumption is “11.1 km per liter of gasoline. "Met. On the other hand, the average fuel consumption when running on urban areas and traveling long distances (cumulative total of 300 km or more) with the “HHO gas generator-equipped vehicle” using the first measurement vehicle is 1 liter of gasoline. It was “18.8 km”. As described above, in the first measurement vehicle, the fuel consumption of the “vehicle equipped with the HHO gas generator” was improved by approximately 69% compared to the case of the “vehicle not equipped with the HHO gas generator”.

In addition, as a result of measuring the emission concentration of carbon monoxide (CO) and hydrocarbon (HC) into the atmosphere with the “vehicle not equipped with the HHO gas generator” using the first measurement vehicle, CO is “0 .35 vol% "and HC was" 289 ppm ". On the other hand, as a result of measuring the emission concentration of carbon monoxide (CO) and hydrocarbons (HC) into the atmosphere with the “vehicle with HHO gas generator” using the first measurement vehicle, CO is “0.04 vol%”, HC was “8 ppm”. Thus, in the first measurement vehicle, CO was reduced by almost 88% and HC was reduced by 97%.

Next, when using the second vehicle for measurement and driving in an urban area and traveling long distances (total of 200 km or more) with an “HHO gas generator non-equipped vehicle”, the average fuel consumption is “11. 7 km ". On the other hand, the average fuel consumption when running in urban areas and traveling long distances (cumulative total of 200 km or more) with a “HHO gas generator-equipped vehicle” using the second vehicle for measurement is 1 liter of gasoline. It was “17.8 km”. Thus, in the second vehicle for measurement, the fuel consumption of the “vehicle with the HHO gas generator” improved by approximately 52% compared to the case of the “vehicle with no HHO gas generator”.

Moreover, as a result of measuring the emission concentration of carbon monoxide (CO) and hydrocarbons (HC) into the atmosphere with a “vehicle not equipped with a HHO gas generator” using the second measurement vehicle, CO was “0 .32 vol% "and HC was" 186 ppm ". On the other hand, as a result of measuring the emission concentration of carbon monoxide (CO) and hydrocarbons (HC) into the atmosphere with the “vehicle with HHO gas generator” using the second measurement vehicle, CO is “0.05 vol%”, HC was “45 ppm”. Thus, in the second measurement vehicle, CO was reduced by almost 84% and HC was reduced by 76%.

In addition, when the third vehicle for measurement is used for “urban vehicle and long-distance driving with a vehicle not equipped with an HHO gas generator” (total of 200 km or more), the average fuel consumption is “12.5 km per liter of gasoline. "Met. On the other hand, the average fuel consumption when running on an urban area and traveling long distances (cumulative total of 300 km or more) with a “HHO gas generator-equipped vehicle” using a third measurement vehicle is 1 liter of gasoline. It was “19.3 km”. Thus, in the third measurement vehicle, the fuel consumption of the “vehicle with the HHO gas generator” was improved by about 54% compared to the case of the “vehicle with no HHO gas generator”.

In addition, as a result of measuring the emission concentration of carbon monoxide (CO) and hydrocarbon (HC) into the atmosphere with a “vehicle not equipped with an HHO gas generator” using a third measurement vehicle, CO is “0 .85 vol% "and HC was" 200 ppm ". On the other hand, as a result of measuring the emission concentration of carbon monoxide (CO) and hydrocarbons (HC) into the atmosphere with the “vehicle with HHO gas generator” using the third measurement vehicle, CO is “0.07 vol%”, HC was “70 ppm”. Thus, in the third measurement vehicle, CO was reduced by almost 91% and HC was reduced by 65%.

In the above example, the measurement results of carbon monoxide (CO) and hydrocarbon (HC) are shown as harmful substances contained in the exhaust gas. However, as harmful substances other than CO and HC contained in the exhaust gas, for example, , Sulfur oxide (SOx) and nitrogen oxide (NOx) were also measured, and the measurement data are not shown here. However, in any of the first to third measurement vehicles, “HHO gas generator-equipped vehicle” ", It was confirmed that it could be significantly reduced.

In this way, by installing the HHO gas generator 10, the harmful substances contained in the exhaust gas can be greatly reduced by mixing the HHO gas with high combustion performance so that the gasoline is completely combusted. It is thought that it is because it burns in a close state.

Also, it was confirmed that the engine sound was quieter when "HHO gas generator was installed". This is also considered to be because gasoline is burned in a state close to complete combustion by mixing HHO gas having high combustion performance.

By the way, in the HHO gas generator 10, the electrolytic solution 101 stored in the electrolytic cell 110 gradually decreases, but in the initial state, the amount of the electrolytic solution 101 in the electrolytic cell 110 is satisfied to the appropriate level L1. In this state, it was confirmed by experiments that a typical automobile can travel about 1000 km. In addition, when replenishing the electrolytic solution 101, the cap 171a of the electrolytic solution supply port 171 may be opened to replenish a predetermined amount from the electrolytic solution supply port 171.

[Embodiment 2]
FIG. 8 is a diagram for explaining the HHO gas generator 20 according to the second embodiment. FIG. 8 corresponds to FIG. Note that FIG. 8 differs from FIG. 1 only in that it has a temperature control device 600, and the other components are the same as those in FIG. Yes.

The temperature control device 600 used in the HHO gas generator 20 according to Embodiment 2 is turned off when the temperature of the electrolytic solution reaches the first set temperature, and then the second temperature of the electrolytic solution is lower than the first set temperature. A temperature detection switch (for example, a thermostat) that turns on when the temperature falls to a set temperature is used. In the HHO gas generation device 20 according to the second embodiment, the temperature control device 600 is also referred to as a temperature detection switch 600.

In the HHO gas generator 20 according to the second embodiment, the temperature detection switch 600 measures the temperature of the electrolytic cell 110 and is turned on / off based on the measured temperature. As described above, in the HHO gas generator 20 according to the second embodiment, the temperature of the electrolytic cell 110 is measured and the on / off operation is performed based on the measured electrolytic cell temperature. Since this depends on the temperature of the electrolytic solution 101, hereinafter, “temperature of the electrolytic cell” is expressed as “temperature of the electrolytic solution”.

As shown in FIG. 8, the temperature detection switch 600 is wired so as to be interposed between the positive <+> side terminal of the power supply device 300 and the positive (+) side terminal of each current control unit 210, 220, 230. Has been. Since the temperature detection switch 600 is wired in this way, when the temperature of the electrolyte 101 rises to the first set temperature and the temperature detection switch 600 is turned off, the current control units 210, 220, and 230 are energized. After that, when the temperature of the electrolyte 101 falls to a second set temperature lower than the first set temperature and the temperature detection switch 600 is turned on, the power supply to the current control units 210, 220, and 230 is turned on. To do.

The first set temperature is preferably in the range of 65 ° C. to 75 ° C., and in the HHO gas generator 20 according to Embodiment 2, the first set temperature is 70 ° C. The second set temperature is preferably in the range of 45 ° C to 60 ° C. The second set temperature is preferably as high as possible in the range of 45 ° C. to 60 ° C. This is because after the temperature of the electrolyte solution 101 becomes the first set temperature and the energization is turned off, the energization is turned back on as soon as possible to restart the electrolysis.

By having such a temperature detection switch 600, it is possible to reliably prevent the temperature of the electrolytic solution 101 from becoming higher than 70 ° C.

In addition, the HHO gas generator 20 according to the second embodiment is similar to the HHO gas generator 10 according to the first embodiment, and the anode plate in each electrode 130, 140, 140 is controlled by current control by the current control units 210, 220, 230. The current flowing between the cathode plate can be made uniform and the temperature of the electrolytic solution 101 can be suppressed to an appropriate temperature. However, by controlling the temperature of the electrolytic solution 101 itself, the temperature of the electrolytic solution 101 for some reason. Can be reliably prevented from rising abnormally. That is, in the HHO gas generator 20 according to the second embodiment, double measures are taken to prevent the temperature of the electrolyte solution 101 from rising abnormally.

The temperature detection switch 600 measures the temperature of the electrolytic bath 110. However, if the temperature of the electrolytic solution 101 can be directly measured, the temperature detection switch 600 is immersed in the electrolytic solution 101 and the temperature of the electrolytic solution 101 is reduced. The temperature may be measured directly.

In addition, the HHO gas generator 20 according to the second embodiment is similar to the HHO gas generator 10 according to the first embodiment, as shown in FIG. The same effect as that of the HHO gas generator 10 according to 1 is obtained.

[Embodiment 3]
The HHO gas generator 30 according to the third embodiment is provided with an electrolyte replenishing mechanism 700 that can automatically replenish the electrolyte 101 in order to keep the electrolyte 101 in the electrolytic cell 110 in an appropriate amount. .

FIG. 9 is a view for explaining the HHO gas generator 30 according to the third embodiment. Note that the HHO gas generator 30 according to the third embodiment also includes the electrolyzer 100, the current control units 210, 220, and 230, and the power supply device 300, similar to the HHO gas generator 10 according to the first embodiment. However, in FIG. 9, the current control units 210, 220, 230 and the power supply device 300 are not shown. Further, the electrolyzer 100 shown in FIG. 9 is a view of the electrolyzer 100 in FIG. 1 as viewed in the direction of the arrow b. In FIG. 9, the same components as those in FIG. Yes. Further, the illustration of electrodes provided in the electrolytic cell 110 is also omitted.
