adopt above-mentioned scheme: hydrogen fuel cell waste gas gets into the inside of left end flow distribution box 4 through air inlet 3, and the inside waste gas of left end flow distribution box 4 is more, will condense into water, and water is collecting in the inside that flows into humidifier 1 through inlet tube 5.
The internal working principle of the humidifier is omitted for convenience of showing the improved content part.
The working principle and the using process of the invention are as follows:
firstly, an air inlet 3 is butted with a waste gas outlet of a hydrogen fuel cell, when the hydrogen fuel cell works, a starting motor 25 drives a fan blade 22 to rotate, fog generated inside a humidifier 1 is discharged through a humidifying exhaust port 2, waste gas generated by the hydrogen fuel cell enters the interior of a flow dividing box 4 through the air inlet 3, the fog generated by the humidifier 1 is injected into the heat exchange tube 18 and the heat exchange bin 9 through the flow dividing box 4 through two air inlet tubes 19 and a communicating tube 24 respectively, the fog generated by the humidifier 1 passes through two heat exchange plates 17 and the interior of the heat exchange tube 18, the fog is heated through the waste gas inside the heat exchange tube 18 due to higher temperature of the waste gas, the fog generated by the humidifier 1 can be heated, the waste gas enters the interior of the heat exchange bin 9 through the communicating tube 24 at the left end, at the moment, two memory metals 12 are heated, the two memory metals 12 drive the heat exchange bin 9 to move downwards due to resetting and shrink, the four second springs 21 are compressed, the bottom of the sealing bin 9 is contacted with the top of a sealing block 13, the interior of the heat exchange bin 9 is sealed by a sealing gasket 28, the heat exchange tube 9 is located in the interior of the heat exchange tube 1, the water, the humidifier 1 is stably discharged from the exhaust tube 4 through the exhaust tube 18, the exhaust tube 4, and the humidifier 1, the exhaust tube 4 at the interior of the humidifier 1, the humidifier 1 is stably discharged through the heat exchange tube 4;
waste gas meets the lower fog of temperature in the inside of heat exchange tube 18 and heat transfer storehouse 9, hydrogen fuel cell waste gas will condense into water, the inside of heat exchange tube 18 that will get into water storage tank 23 is collected, when collecting more, the weight of water is heavier extrudeing fourth spring 30, water will discharge the inside of humidifier 1 through water storage tank 23, after work is accomplished, the inside cooling back of humidifier 1, two memory metals 12 will become soft, four second springs 21 will promote heat transfer storehouse 9 and upwards move this moment, seal block 13 will break away from the bottom of heat transfer storehouse 9, the inside water of heat transfer storehouse 9 will fall into the inside bottom of humidifier 1 and continue to circulate and use this moment.
