In practical application, the air inlet and the air outlet are both arranged on the side wall of the tank body 11.
In some embodiments, the humidifying device further includes a partition component 16, and the partition component 16 is disposed in the inner cavity of the tank 11 to partition the inner cavity of the tank 11 into a first humidifying cavity 111 and a second humidifying cavity 112, and is capable of allowing the humidifying medium to pass into the second humidifying cavity 112 and blocking the gas from passing into the second humidifying cavity 112.
Further, the partition assembly 16 includes a partition plate 161, and the partition plate 161 is disposed in the tank 11 to partition the inner chamber of the tank 11 into the first humidification chamber 111 and the second humidification chamber 112. In practice, the partition 161 is disposed in a horizontal direction.
It is understood that the partition 161 divides the inner cavity of the tank 11 into the first humidification chamber 111 and the second humidification chamber 112, the bottom end of the first humidification chamber 111 and the top end of the second humidification chamber 112 are both the partition 161, and the gas inlet and the gas outlet are both opened in the tank 11, so that the gas inlet and the gas outlet are opened in the side walls of the first humidification chamber 111 and the second humidification chamber 112.
In addition, the communicating tube 13 penetrates the partition plate 161, and the position where the communicating tube 13 penetrates the partition plate 161 is hermetically connected to the partition plate 161, so that the gas inside the first humidification chamber 111 enters the second humidification chamber 112 through the communicating tube 13.
In some embodiments, the partition assembly 16 further includes a drain valve 162, the drain valve 162 is disposed on the partition 161, and the drain valve 162 has a communication state for communicating the first humidification chamber 111 and the second humidification chamber 112, and a blocking state for partitioning the first humidification chamber 111 and the second humidification chamber 112.
When the depth of the humidification medium at the bottom of the first humidification chamber 111 is greater than or equal to the preset depth, the drain valve 162 enters a communication state, and the humidification medium at the bottom of the first humidification chamber 111 can enter the second humidification chamber 112 through the drain valve 162; when the depth of the humidification medium at the bottom of the first humidification chamber 111 is less than the preset depth, the drain valve 162 enters the shut-down state.
That is, the humidifying medium at the bottom of the first humidifying chamber 111 is accumulated to a certain depth and then discharged into the second humidifying chamber 112, and when the amount of the humidifying medium accumulated at the bottom of the first humidifying chamber 111 is small, the first humidifying chamber 111 and the second humidifying chamber 112 are not communicated with each other. Therefore, the humidifying medium forms a liquid sealing layer at the bottom of the first humidification chamber 111, and the first humidification chamber 111 is prevented from being directly communicated with the second humidification chamber 112, so that the gas entering the first humidification chamber 111 is prevented from directly entering the second humidification chamber 112 without undergoing humidification treatment in the first humidification chamber 111, and the humidification effect of the gas is ensured.
Specifically, drain valve 162 is an automatic drain valve, and partition assembly 16 includes a plurality of drain valves 162.
In other embodiments, the drain valve 162 in the above embodiments is replaced by a drain pipe, the drain pipe is disposed on the partition 161, the liquid inlet end of the drain pipe is communicated with the first humidification chamber 111, the liquid outlet end of the drain pipe is communicated with the second humidification chamber 112, and the liquid inlet end of the drain pipe has a height lower than the liquid outlet end of the drain pipe.
Thus, according to the principle of the communicating vessel, it can be determined that the drain pipe has a liquid sealing effect, and the humidifying medium can be discharged from the drain pipe into the second humidifying chamber 112 only when the accumulation depth of the humidifying medium is higher than the height of the liquid outlet end of the drain pipe.
Of course, the drain pipe may be in other forms, for example, the drain pipe is a U-shaped pipe, the liquid inlet end and the liquid outlet end of the drain pipe are top portions, and when the height of the liquid outlet end of the drain pipe is higher than the height of the bottom portion of the drain pipe by at least the diameter of the drain pipe, a liquid sealing layer can be formed in the drain pipe regardless of the height between the liquid inlet end and the liquid outlet end of the drain pipe.
Alternatively, a drain pipe may be omitted, and a drain passage may be directly formed in the partition plate 161, and the form of the drain passage is the same as that of the above drain pipe, or the drain passage may extend in the vertical direction, and the aperture of the opening of the drain passage communicating with the second humidification chamber 112 may be smaller than the diameter of the opening at other positions, and a sealing ball may be placed in the drain passage.
When there is no humidification medium or there is less humidification medium in the drainage channel, the sealing ball can seal the opening of the drainage channel communicating with the second humidification chamber 112, thereby preventing the gas from entering the second humidification chamber 112 through the drainage channel; when more humidification media is present in the drainage channel, the sealing ball floats upwards due to the buoyancy, and the humidification media can flow from the drainage channel to the second humidification chamber 112.
It should be noted that when the partition 161 is used in conjunction with the drain pipe, a certain amount of humidification medium needs to be sprayed into the first humidification chamber 111 to form the liquid enclosure in advance.
When adopting flowing back passageway and ball sealer cooperation, can also set up the baffle in the bottom of first humidification chamber 111, the flowing back passageway is not sealed to the baffle, is only used for restricting ball sealer come-up in-process drainage flowing back passageway, and the ball sealer come-up in addition when contacting with the baffle, and the ball sealer is no longer come-up, and ball sealer and baffle all can not seal the flowing back passageway.
In addition, in the above embodiments, the partition component 16 may connect the first humidification chamber 111 and the second humidification chamber 112, in other embodiments, the partition component 16 may be used only for partitioning the first humidification chamber 111 and the second humidification chamber 112, and the humidification medium accumulated at the bottom of the first humidification chamber 111 may be discharged through another opening, which is not limited herein.
In some embodiments, snorkel 13 extends into the top of first humidification chamber 111 at one end and into the bottom of second humidification chamber 112 at the other end, and bubble humidification assembly 14 is positioned between the outlet port and the end of snorkel 13 that extends into second humidification chamber 112.
The gas fed into the first humidification chamber 111 from the gas inlet first enters the bottom of the first humidification chamber 111, the shower assembly 12 humidifies the gas while the gas flows from the bottom to the top communicating pipe 13, the gas fed into the second humidification chamber 112 from the other end of the communicating pipe 13 enters the bottom of the second humidification chamber 112, and the gas passes through the humidification bubble generating assembly 14 to be humidified for the second time while flowing to the gas outlet at the top.

Further, the water inlet is located at the top end of the first humidification chamber 111, the spraying component 12 includes a connecting pipe and a water distributor, the connecting pipe is connected between the water inlet and the water distributor, the water distributor is disposed at the top of the first humidification chamber 111 and located above the connecting pipe, the water distributor is used for dispersedly spraying the humidification medium into the first humidification chamber 111, and dispersedly spraying the humidification medium onto the spraying filler 17.
In practical application, the humidifying device further comprises a circulation assembly 22, wherein the circulation assembly 22 is communicated with the water outlet and the water inlet and is used for inputting the humidifying medium discharged from the water outlet into the water inlet and further inputting the humidifying medium into the spraying assembly 12.

In addition, since the humidifying medium is used for humidifying the gas, the humidified gas is discharged, so that the humidifying medium is still reduced, and when the humidifying medium is reduced to a level that is lower than the minimum level in the second humidification chamber 112, the water supplement assembly 20 inputs the humidifying medium into the second humidification chamber 112, so as to ensure that the amount of the humidifying medium in the tank 11 and the circulation assembly 22 meets the humidification requirement.
In other embodiments, the tank 11 may be opened with an inlet opening communicating with the second humidification chamber 112, and the inlet opening is also communicated with the circulation component 22, and the circulation component 22 circulates the humidification medium discharged from the outlet opening back to the first humidification chamber 111 and the second humidification chamber 112.
In some embodiments, the circulation assembly 22 includes a water inlet pipe 221, a heating pipe 222, a cooling pipe 223, and a water outlet pipe 224, wherein a liquid inlet end of the water inlet pipe 221 is connected to the water outlet, a liquid outlet end of the water outlet pipe 224 is connected to the water inlet, liquid inlet ends of the heating pipe 222 and the cooling pipe 223 are connected to the liquid outlet end of the water inlet pipe 221, and liquid outlet ends of the heating pipe 222 and the cooling pipe 223 are connected to the liquid inlet end of the water outlet pipe 224.
Further, the circulation assembly 22 further includes a heater 225 and a cooler 226, the heater 225 is disposed on the heating pipe 222 for heating the humidification medium in the heating pipe 222, and the cooler 226 is disposed on the cooling pipe 223 for cooling the humidification medium in the cooling pipe 223.
In this way, the humidification medium heated by the heater 225 and cooled by the cooler 226 is mixed in the outlet pipe 224, and the temperature of the humidification medium in the heating pipe 222 and the cooling pipe 223 can be adjusted, so that the temperature of the humidification medium mixed in the outlet pipe 224 can be adjusted.
In practical applications, the circulation module 22 further includes a cooling valve 227, and the cooling valve 227 is disposed on the cooling pipe 223 and is used for controlling the opening and closing of the cooling pipe 223.

It should be noted that, since the humidification medium humidifies the gas, the temperature of the humidification medium also affects the temperature of the gas, and the humidity and the temperature of the gas input into the cell stack are both effective, it is necessary to ensure the humidity and the temperature of the gas output from the gas outlet at the same time. However, since the heat of the humidification medium is lost during the circulation of the humidification medium, the humidification medium needs to be heated by the heater 225, and the temperature of the humidification medium needs to be adjusted before the humidification medium is supplied to the shower unit 12 in order to avoid the gas temperature from being excessively high due to the excessively high temperature of the humidification medium.
Specifically, when the temperature of the humidification medium in the water outlet pipe 224 is too high, the cooling valve 227 is opened, the humidification medium with a lower temperature enters the water outlet pipe 224 to be mixed with the humidification medium with a higher temperature, and the temperature of the humidification medium is reduced after mixing until the requirement is met; when the temperature of the humidification medium in the water outlet pipe 224 is too low, the opening degree of the cooling valve 227 is reduced or disconnected, the input amount of the humidification medium with lower temperature is reduced, and the temperature of the humidification medium in the water outlet pipe 224 is increased until the requirement is met.
Therefore, it can be understood that the temperature of the humidification medium heated by the heater 225 will generally be higher than the desired temperature. Meanwhile, when the flow rate in the heating line 222 is constant, the effect of the heater 225 on heating the humidification medium is the same, that is, the temperature of the humidification medium output from the heating line 222 to the outlet line 224 is the same.
