The water contains, for example, about 50 to 500 mg / liter of silica, alumina, calcia, magnesia or the like or hydrates thereof. These impurities may accumulate in the electrolytic cell as the gas evolves. In that case, the electrolytic cell must be disassembled and cleaned to remove these accumulations.

The frequency adjustment circuit 67 preferably has a function of automatically following the frequency of the current pulse with the resonance frequency of the alkaline aqueous solution.

  Further, as shown in FIG. 7, the pulse sharpening circuit 64 may be provided with a capacitor controller 68 and a capacitor 69 instead of the frequency adjustment circuit 67 in the configuration of FIG. 6. Reference numeral 70 denotes a storage battery. In the pulse steepening circuit 64 of FIG. 7, the current pulse is input to the capacitor controller 68, and the capacitor controller 68 instructs the capacitor 69 to charge and discharge, and the current pulse can be sharpened.

  Further, as shown in FIG. 8, the pulse sharpening circuit 64 may be obtained by adding a capacitor controller 68 and a capacitor 69 to the configuration of FIG. As a result, the current pulse sharpened by the frequency adjustment circuit 67 can be further sharpened by the capacitor 69 by the capacitor controller 68.

  In the present embodiment, the control unit 5 includes a power supply control unit that controls the power supply unit 4, a pressure monitoring unit, a temperature monitoring unit, and the like. The display unit 6 includes a power switch (not shown), a power-on lamp that is turned on when the power is turned on, and a power indicator (none of which are shown). Further, it has a pressure meter switch 73 and a temperature meter switch 74, and is provided in the gas pressure and gas generation means 1 after being filtered by the first ceramic filter 51 sent out from the first filter tank 32. The temperature detected by the temperature sensor 71 is displayed. And the control part 5 has a function which gives an alarm and stops an apparatus, when these pressure and temperature become higher than predetermined value. The control unit 5 controls a pressure switch 72 provided in the gas supply line 52.

  The power supply means 4 has an automatic input switch (not shown) that protects the electric device therein from overvoltage and short circuit (short circuit). When the power supply means 4 is switched on, the starter is driven. A fan (not shown) provided in each part rotates, power is supplied to a control power bridge (not shown), and a power indicator on the display unit 6 is turned on.

  In the gas generator configured in this way, a pulsed DC voltage is applied from the power supply means 4 to the electrodes 14 of the gas generation means 1 to decompose the electrolyte held in the space between the electrodes 14 and gas The generated gas is cooled by the cooler 31 and filtered by the first filter tank 32, the second filter tank 33, and the last filter 34, and the gas that has passed through the last filter 34 passes through the pipe 35 and is an engine burner or the like. Is supplied to the load equipment 60 and used as gas energy.

  At this time, when a current pulse is applied to the gas generating means 1, the electrolyte is decomposed to generate gas, but the present inventor has determined that the amount of gas generated (gas generation amount) at this time is I found out that it depends only on the height. That is, conventionally, in order to increase the amount of gas generated, it was thought that it was necessary to increase the supply power (current). However, according to the knowledge of the present inventors, the amount of gas generated (gas generation) It was newly found that the amount) can be increased without increasing the power supply by increasing the height of the current pulse without increasing the area of the current pulse. That is, it has been found that the amount of gas generated per unit power (gas generation amount) can be dramatically increased by making the current pulse as steep as possible.

  Thus, in the present embodiment, the pulse steepening circuit 64 sharpens the pulsed current after rectification by the AC / DC converter (rectifier circuit) 62 and frequency conversion by the frequency conversion circuit 63. That is, the current waveform when rectified by the AC / DC converter (rectifier circuit) 62 is a rectangular wave as shown in FIG. 9, and when it is applied to the electrode, it has a pointed shape as shown in the schematic diagram of FIG. Although it becomes a current pulse, the voltage has conventionally been low and has a comparatively gentle shape. In such a situation, in order to increase the gas generation amount (gas generation amount), the duty ratio must be increased while the wave height is maintained, and the current value must be increased. As a result, supply power (ie, power consumption) is increased. Was accompanied by an increase. However, in the present embodiment, by using the pulse steepening circuit 64, the duty ratio is lowered to increase the peak height while reducing the half width of the current pulse as shown in the schematic diagram of FIG. Thus, the gas generation amount (gas generation amount) can be increased without increasing the current pulse area, that is, without increasing the power consumption. In addition, the waveform of the current pulse in FIGS. 9 to 11 is schematically shown, and the actual waveform has a slightly different shape.

  Then, by using the pulse steepening circuit 64 as shown in FIG. 6, the duty ratio is lowered (desirably 0.2 or less) by the PWM circuit 65, and the voltage is preferably raised by the DCDC converter 66. Further, the frequency adjustment circuit 67 adjusts the frequency of the pulse current to the resonance frequency f = 1 / (2π√ (LC)) determined by the inductance L and the capacitance C of the alkaline aqueous solution. With the resonance function, the current pulse can be remarkably sharpened, and the amount of gas generated per unit power (gas generation amount) can be increased.

  Further, by using the pulse sharpening circuit 64 as shown in FIG. 8, the duty ratio is lowered (desirably 0.2 or less) by the PWM circuit 65, and preferably after the voltage is raised by the DCDC converter 66. The current pulse is input to the capacitor controller 68, and the capacitor controller 68 instructs the charge and discharge amount and timing to the capacitor 69, so that the current pulse can be sharpened, and the amount of gas generated per unit power (gas generation) Amount) can be increased.

  Further, by using the pulse sharpening circuit 64 as shown in FIG. 7, the current pulse can be further sharpened by the synergistic effect of the frequency adjustment circuit 67, the capacitor controller 68, and the capacitor 69. The amount of gas generated per unit power (gas generation amount) can be further increased.

  In addition, the gas generator of this embodiment uses an alkaline aqueous solution, for example, 3 to 15% (preferably 10%) KOH solution as electrolyzed water, and electrolyzes it using a 100 V commercial power source to generate it. The gas is degassed and dehydrated with a filter, and only the gas component is taken out. This is used as it is or enriched with a riching agent such as gasoline to produce fuel gas. Gas energy that can be used in place of ordinary fuel such as propane can be obtained.

  Furthermore, since the gas is obtained by electrolytic decomposition of water, it can be obtained without pollution and at low cost.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to the said embodiment. For example, the enrichment agent is not limited to gasoline, and other fuels such as kerosene can be used. Further, fuel gas containing gas may be supplied to load equipment other than the engine / burner.

  The present invention will be described using a gas generator according to an embodiment. In addition, the present invention can be used for any device other than the gas generator described below, as long as it generates gas by electrolysis (device, machine, component, system, application, etc.).

Example 1
In this example, oxyhydrogen gas was generated under the following generation conditions using the gas generator 100 according to the embodiment.
0) Electrode: Stainless steel sheet (SUS316L)
1) Power supply: commercial power supply AC 100V, pulse frequency 50-300Hz
2) Supply current: 10A-50A
3) Electrolyte: 10% KOH
4) Aqueous solution mixer: 3.8 liters in volume

  Under these conditions, the amount of oxyhydrogen gas actually generated for the one rectified by the AC / DC converter (rectifier circuit) and the one obtained by further doubling the current peak by the pulse sharpening circuit shown in FIG. Compared. As a result, the former was 300 liters / hour / kW, while the latter was 600 liters / hour / kW.

  FIG. 12 (a) shows an example of the experimental result (100V, 5A) of the gas generation amount corresponding to the frequency. FIG. 12B shows an example of the experimental result (100 V, 10 A) of the gas generation amount Qg corresponding to the frequency f. As shown in FIGS. 12A and 12B, the frequency fg of the pulse current is near the resonance frequency f = 1 / (2π√ (LC)) determined by the inductance L and capacitance C of the alkaline aqueous solution (for example, In this experiment, the gas generation amount Qg was maximized at 125 Hz). Further, as shown in FIGS. 12A and 12B, the frequency fg of the pulse current is in the vicinity of the resonance frequency f = 1 / (2π√ (LC)) determined by the inductance L and capacitance C of the alkaline aqueous solution. (For example, in this experiment, 125 Hz), the gas generation amount Qg became a maximum value that increased rapidly. That is, according to the gas generator (oxyhydrogen gas generator) according to the present invention, the area of the current pulse of the pulsed current obtained by the rectifier circuit (FIG. 5) using the pulse sharpening circuit (FIG. 5) is reduced. Since the peak can be increased and sharpened without increasing, the frequency fg of the pulse current can be controlled to increase the gas generation amount Qg per unit power.

  FIG. 13 shows an example of an experimental result of the gas generation amount Qg corresponding to the peak current value Ig. As shown in FIG. 13, the gas generator changes the peak current value Ig of the current pulse of the pulsed current obtained by the rectifier circuit (FIG. 5) using the pulse sharpening circuit (FIG. 5). The gas generation amount Qg can be adjusted. That is, according to the gas generator (oxyhydrogen gas generator) according to the present invention, the gas is obtained by changing the peak current value Ig of the current pulse of the pulsed current obtained by the rectifier circuit using the pulse sharpening circuit. Since the generation amount Qg can be adjusted, a desired amount of gas can be generated according to the usage situation. Further, according to the gas generator (oxyhydrogen gas generator) according to the present invention, the gas generation amount Qg can be adjusted by changing the peak current value Ig of the current pulse of the pulsed current, so that the high response. Therefore, a gas storage device (high-pressure gas cylinder, gas storage alloy, other gas storage device, etc.) is not required, and a necessary amount of gas can be generated when necessary.

Here, the control unit 5 converts AC to DC using the rectifier circuit 62 (FIG. 5) and converts it into a pulsed current (rectifier step), and uses the pulse steepening circuit 64 (FIG. 5). The current pulse (for example, FIG. 11) of the converted pulse current is sharpened (steepening step). Thereafter, the gas generation device 100 proceeds to step S1403.

  Next, in step S1403, the gas generation apparatus 100 uses the gas generation means 1 to electrolyze the electrolyte solution using the electric energy supplied from the power supply means 4 (gas generation step). Thereafter, the gas generation device 100 proceeds to step S1404.

  In step S1404, the gas generation device 100 detects the amount of gas generated by the gas generation unit 1 using the detection unit 7 (detection step). Thereafter, the gas generation device 100 proceeds to step S1405.

  In step S <b> 1405, the gas generation device 100 uses the control unit 5 to adjust the gas generation amount of the gas generated by the gas generation unit 1. Here, the control unit 5 controls the operations of the rectifier circuit 62 and the pulse sharpening circuit 64 to adjust the gas generation amount. Specifically, the control unit 5 changes the frequency fg of the pulsed current (for example, FIG. 12) and / or the maximum amplitude of the current pulse (for example, FIG. 13) based on the gas generation amount detected by the detection means 7. Thereafter, the gas generation device 100 proceeds to step S1406.

  In step S1406, the gas generator 100 uses the control unit 5 to determine whether to repeat the operation of generating gas based on the detection result detected in step S1405 (control step). For example, the control unit 5 can further determine whether to repeat the operation of generating the gas by further using information input from the outside of the gas generator 100. Thereby, the gas generator 100 can generate a desired amount of gas. Thereafter, when it is determined that the operation to be generated is repeated, the gas generation device 100 returns to step S1402. If it is determined that the operation to be generated is to be terminated, the gas generating device 100 proceeds to “END” in the drawing and ends the operation.

  As described above, in the gas generation method according to this example, the area of the current pulse of the pulsed current obtained by the rectifier circuit is increased by the pulse sharpening circuit, as in the gas generator 100 according to the embodiment. Since the peak can be made higher and sharper, the amount of gas generated per unit power can be increased.
