The explanation of the water electrolysis hydrogen production device of this embodiment is as follows:
the electrolyte inlet of the hydrogen production electrolytic tank 15 in this embodiment is connected to the first outlet 112 of the heat exchanger, and the electrolyte outlet of the hydrogen production electrolytic tank is connected to the inlet of the water tank 13. The inlet of the electrolyte circulation pump 12 is connected with the outlet of the water tank 13, and the outlet of the electrolyte circulation pump 12 is connected with the second inlet 113 of the heat exchanger 11. Electrolyte in the water tank 13 is pumped into the hydrogen production electrolytic tank 15 through the electrolyte circulating pump 12 to perform electrochemical reaction to generate hydrogen. When the hydrogen production electrolytic tank 15 is just started or the temperature of the water tank 13 does not reach the set value, the first electric valve 3, the third electric valve 5 and the fourth electric valve 6 are in a closed state, and the second electric valve 4 and the fifth electric valve 8 are in an open state. Cooling water enters the rectifier 7 from the water outlet of the heat exchange pump 1, under the condition that the rectifier 7 outputs direct current to supply power to the hydrogen production electrolytic tank 15, the cooling water brings heat out of the rectifier 7, then enters the heat exchanger 11 from the water outlet of the rectifier 7 through the first water inlet of the heat exchanger 11, and the heat brought out of the rectifier 7 is transferred to electrolyte at the other side, so that the temperature of the electrolyte is increased, the temperature rise time of the electrolytic tank 15 is shortened, and the efficiency of the electrolytic tank 15 is improved. The temperature of the cooling water is reduced after heat exchange, the cooled cooling water returns to the heat exchange pump 1 from the second outlet 114 of the heat exchanger 11 through the one-way valve 10, the regulating valve 9 and the second electric valve 4 to be circularly reciprocated, and the energy which is inevitably wasted by the rectifier 7 due to the self efficiency problem is reused, so that the efficiency of the whole electrolytic hydrogen production system is improved, and the energy consumption is reduced. When the thermocouple (temperature measuring part 14) detects that the temperature of the water tank 13 is higher than the set value, the second and fifth electric valves 4 and 8 are closed, and the first, third, fourth and regulating valves 3, 5, 6 and 9 are opened. Cooling water enters the heat exchange pump 1 from the outlet of the cooler 2, then the cooling water respectively passes through the rectifier 7 and the third electric valve 5 to cool the rectifier 7 and electrolyte passing through the heat exchanger 11 in two ways, and the opening of the valve of the regulating valve 9 is regulated, so that the electrolytic tank 15 is maintained at a stable temperature.
From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:
the electrolytic water hydrogen production device of the present invention comprises a heat exchanger 11, wherein the heat exchanger 11 comprises a first inlet 111, a first outlet 112 and a second inlet 113; a water tank 13 for containing an electrolyte, the water tank 13 being connected to the first inlet 111; an electrolytic tank 15 connected to the first outlet 112 so that the electrolyte in the water tank 13 sequentially passes through the first inlet 111, the heat exchanger 11, and the first outlet 112 to enter the electrolytic tank 15; and the rectifier 7 is connected with the electrolytic tank 15 to output direct current to the electrolytic tank 15, the rectifier 7 comprises a water cooling part for absorbing heat of the rectifier 7, and a water outlet of the water cooling part is connected with the second inlet 113, so that fluid in the water cooling part enters the heat exchanger 11 through the second inlet 113, and the fluid in the water cooling part exchanges heat with electrolyte in the heat exchanger 11. With the adoption of the arrangement, the rectifier 7 adopts the water-cooled rectifying source with the water cooling part, useless heat which is consumed by the water-cooled rectifying source is converted into energy for heating electrolyte in the electrolytic tank, so that the heating time of the electrolyte in the electrolytic tank 15 is reduced, the working efficiency of the electrolytic tank 15 is improved, and the problem of low energy utilization rate of the electrolytic water hydrogen production device in the prior art is solved.
