As shown in fig. 1 and 2, a humidifying device 100 according to an embodiment of the present invention includes a humidifying tank 10, a bubbling filler, a built-in pipe 20, and a spraying assembly 30.

The humidifying tank 10 is provided with a humidifying cavity 13, and a gas inlet 14 and a gas outlet 15 which are communicated with the humidifying cavity 13, wherein the gas inlet 14 and the gas outlet 15 are positioned at the top of the humidifying tank 10.

The built-in pipe 20 is provided in the humidification chamber 13 to divide the humidification chamber 13 into a shower chamber 131 and a bubbling chamber 132, and the shower chamber 131 and the bubbling chamber 132 are communicated with each other through one end of the built-in pipe 20.

The tympanic bulla packs and sets up in tympanic bulla chamber 132, and built-in pipe 20 intercommunication sprays the one end in chamber 131 and tympanic bulla chamber 132 and stretches into the tympanic bulla and packs in, and spray assembly 30 sets up in the top of humidification jar 10, and is located and sprays the chamber 131 for spout humidification medium in toward spraying the chamber 131, carry out the humidification to the gas that sprays in the chamber 131.

It is understood that inner pipe 20 divides humidification chamber 13 into spraying chamber 131 and bubbling chamber 132, spraying chamber 131 and bubbling chamber 132 are communicated with each other through one end of inner pipe 20, that is, one end of inner pipe 20 is hermetically connected to the inner wall of humidification chamber 13, and the other end is used to communicate spraying chamber 131 and bubbling chamber 132 with each other,

meanwhile, the spraying chamber 131 is communicated with the gas inlet 14, the bubbling chamber 132 is communicated with the gas outlet 15, the gas flows into the spraying chamber 131 from the gas inlet 14, then enters the bubbling chamber 132, and finally is discharged from the gas outlet 15, and one of the spraying chamber 131 and the bubbling chamber 132 is an inner chamber of the inner pipe 20. In practice, the spray chamber 131 is the inner chamber of the inner cannula 20.

By arranging the humidifying device, the gas enters the spraying cavity 131 from the gas inlet 14, the spraying assembly 30 humidifies the gas entering the spraying cavity 131 for the first time, the humidifying medium sprayed into the spraying cavity 131 flows to one end of the built-in pipe 20 extending into the bubbling filler along the pipe wall, the bubbling filler can be wetted, and the gas is discharged from the end. The gas exiting the spray chamber 131 may be subjected to a second humidification of the bubbling packing, and the bubbling packing may also drive off excess droplets in the gas. So, gaseous humidification twice through, improves the humidification effect, and unnecessary liquid drop can be got rid of to the tympanic bulla filler moreover, improves the accuracy and the stability of humidification.

In addition, the humidifying device arranges the spraying component 30 and the bubbling filler in the same humidifying tank 10, simplifies the structure and reduces the cost under the condition of realizing twice humidifying gas.

It should be noted that the gas input from the gas inlet 14 is dry gas or gas with a certain humidity, and is usually hydrogen or oxygen, and the humidifying medium sprayed into the inner pipe 20 by the spraying assembly 30 is deionized water.

In some embodiments, the humidification tank 10 includes a tank 11 and a cover 12, the tank 11 has a humidification chamber 13 and a top opening and an air outlet 15 communicating with the humidification chamber 13, the air outlet 15 is opened on a side wall of the tank 11, the cover 12 is hermetically connected to the top opening of the tank 11 to close the top opening, the cover 12 is opened with an air inlet 14 communicating with the humidification chamber 13, one end of the inner pipe 20 is hermetically connected to the cover 12, and the air inlet 14 communicates with an inner cavity of the inner pipe 20, that is, the spraying chamber 131.

Specifically, the can 11 is substantially cylindrical, and the lid 12 is a circular lid.

In some embodiments, the top of the humidification tank 10 is further opened with a water inlet 16 communicated with the spray chamber 131, that is, one end of the inner pipe 20 connected with the top of the humidification tank 10 is communicated with the water inlet 16, and the water inlet 16 is communicated with the spray assembly 30 located in the spray chamber 131 for inputting the humidification medium to the spray assembly 30.

It will be appreciated that the water inlet 16 may communicate between the spray chamber 131 and the exterior of the humidification tank 10, while the spray assembly 30 communicates with the water inlet 16, and the water inlet 16 is used to input the humidification media to the spray assembly 30, so that the spray assembly 30 is disposed within the spray chamber 131, i.e., within the inner conduit 20, and at the top of the inner conduit 20 for humidifying the gas entering the gas inlet 14.

In practical applications, the water inlet 16 is disposed on the cover 12 and adjacent to the air inlet 14. Specifically, the number of the water inlets 16 is three, the air inlet 14 is arranged at the center of the cover body 12, and the three water inlets 16 are uniformly spaced around the air inlet 14.

It should be noted that the number of the water inlets 16 may be other, and for setting a plurality of water inlets 16, a plurality of spraying assemblies 30 may be correspondingly set, each spraying assembly 30 is communicated with the corresponding water inlet 16, or one spraying assembly 30 may be set, and a plurality of water inlets 16 are adopted to supply water to the same spraying assembly 30, so as to improve the flow rate of the humidification medium, thereby ensuring the humidification capability when the gas flow rate is larger.

In some embodiments, spray assembly 30 includes a communication tube having one end in communication with water inlet 16 and another end in communication with a water distributor for uniformly dispersing the humidification medium within spray chamber 131 to humidify the gases within spray chamber 131.

It should be explained that the deionized water is inputted into the water inlet 16 and inputted into the water distributor through the communicating pipe, and then is dispersed by the water distributor and then is sprayed into the spray chamber 131, and the dispersed deionized water is mixed with the dry gas, thereby performing the first humidification of the dry gas.

It will also be appreciated that the water distributor acts like a shower head to distribute the humidification media evenly within the spray chamber 131, i.e., to disperse the humidification media in a stream into smaller droplets that are then sprayed into the spray chamber 131.

Further, the spray assembly 30 further includes a first temperature detector and a first heater, the first temperature detector is disposed in the communicating pipe and is used for detecting the temperature of the humidification medium in the communicating pipe, the first heater is disposed in the communicating pipe and is connected to the first temperature detector, and the first heater is used for heating the humidification medium.

The humidifying medium in the communicating pipe is heated by the first heater, so that the humidifying medium dispersed into smaller water drops is prevented from being condensed into larger liquid drops after being sprayed into the spraying cavity 131, and the humidifying effect is improved.

It should be noted that, in the case where the air pressure is kept constant with the water vapor content in the air being constant, the temperature at which the air is cooled to saturation is the dew point temperature. In the humidification process, the water vapor in the spraying cavity 131 circularly flows, so that the water vapor content in the spraying cavity 131 is unchanged, the air pressure is also constant, and the dew point temperature in the spraying cavity 131 at the moment can be obtained through detection.

According to the detected dew point temperature, the humidifying medium is heated by the first heater, so that the temperature of the humidifying medium in the communicating pipe or the water distributor is ensured to be higher than the dew point temperature, and the humidifying medium sprayed into the spraying cavity 131 is prevented from being condensed into larger liquid drops in the air. Certainly, in practical application, the first heater heats the humidifying medium in the communicating pipe to a temperature 2-5 ℃ higher than the dew point temperature.

Meanwhile, the first heater heats the humidifying medium, so as to prevent the humidifying medium from being pre-condensed into larger liquid drops in the air in the spraying chamber 131, and the humidifying medium is condensed on the inner wall of the spraying chamber 131 when encountering the inner wall of the spraying chamber 131 and then flows to the lower part of the built-in pipe 20 along the inner wall of the spraying chamber 131, so as to wet the bubbling filler below. Of course, the humidifying medium may also flow directly with the gas flow to the underside to wet out the underlying blister pack.

In some embodiments, the humidifying device further comprises a gas distributor 40, wherein the gas distributor 40 is disposed in the spray chamber 131 and is communicated with the gas inlet 14 for distributing the gas input from the gas inlet 14 into the spray chamber 131.

It should be explained that the gas distributor 40 distributes the gas in the shower chamber 131 means that the gas is distributed more uniformly in the shower chamber 131 through the gas distributor 40.

In practice, the gas distributor 40 is located above the spray chamber 131. It can be understood that, the effect of the gas distributor 40 can be understood as slowing down the speed of the gas flowing downwards, and the gas distributor 40 can disperse and input the gas flowing downwards directly into the spraying cavity 131 towards a plurality of directions, so that the dry gas is distributed more uniformly in the spraying cavity 131, the dry gas and the humidifying medium are mixed more fully, and the humidifying effect is improved.

In some embodiments, one end of the built-in pipe 20, which communicates the spraying chamber 131 and the bubbling chamber 132, is provided with a plurality of communication holes 21, each communication hole 21 can communicate the spraying chamber 131 and the bubbling chamber 132, and the gas and the humidification medium in the spraying chamber 131 flow to the bubbling chamber through the plurality of communication holes 21.

The humidifying medium in the spraying chamber 131 flows to the bubbling chamber 132 through the communication holes 21 to wet the bubbling filler, and the gas in the spraying chamber 131 enters the bubbling chamber 132 through the communication holes 21 to further disperse the gas humidified for the first time, so that the humidifying effect of the bubbling filler is improved after the gas enters the bubbling filler.

In practical application, the inner pipe 20 is a circular pipe, and the inner pipe 20 is arranged in the humidifying cavity 13 along the vertical direction and is coaxially arranged with the cylindrical tank 11.

In this way, the gases exhausted through the built-in pipe 20 flow upwards to the exhaust port in the space between the built-in pipe 20 and the inner wall of the humidification chamber 13, the temperature of the built-in pipe 20 is also increased by the humidification medium with higher temperature sprayed by the spraying assembly 30, and the built-in pipe 20 with higher temperature can also insulate the gases flowing to the exhaust port.

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 both the humidity and the temperature of the gas output from the gas outlet 15.

In some embodiments, the end surface of one end of the inner tube 20 is through, the end surface of the other end is closed, the through end surface is connected with the cover 12 in a sealing manner, so that the inner tube 20 is communicated with the air inlet 14 and the water inlet 16, and the side wall of the other end with the closed end surface is provided with a plurality of communication holes 21 to communicate the spraying chamber 131 and the bubbling chamber 132.

In practical application, the plurality of communication holes 21 are equally divided into a plurality of groups, the plurality of communication holes 21 of each group are uniformly arranged at intervals in the vertical direction, and the plurality of groups of communication holes 21 are uniformly arranged at intervals in the circumferential direction of the inner pipe 20. Specifically, the aperture of each communicating hole 21 is 2 mm to 3 mm.

Of course, in other embodiments, the end surface of one end of the inner tube 20 is through, and the end surface of the other end is opened with a plurality of communication holes 21, or the end surface of one end of the inner tube 20 is through, and the end surface and the side wall of the other end are both opened with a plurality of communication holes 21. Communication between the shower chamber 131 and the bubbling chamber 132 can also be achieved.

In some embodiments, the bubble packing is pall ring packing, and when the gas after the first humidification passes through the bubble packing, the bubble packing soaked by the humidification medium can perform the second humidification on the gas and can remove redundant liquid drops in the gas.

In some embodiments, the bottom of the humidification tank 10 is further opened with a water outlet 17 communicating with the bubbling chamber 132 for discharging the accumulated humidification medium at the bottom of the bubbling chamber 132.

Furthermore, the humidifying device also comprises a circulating assembly, wherein the liquid inlet end of the circulating assembly is communicated with the water outlet 17, and the liquid outlet end of the circulating assembly is communicated with the water inlet 16, so that the humidifying medium discharged from the water outlet 17 is conveyed to the water inlet 16, the humidifying medium is recycled, resources are saved, and the cost is reduced.

In some embodiments, the circulation assembly comprises a circulation pipe in communication with the water inlet 16 and the water outlet 17, respectively, and a circulation pump disposed in the circulation pipe for directing the humidification media discharged from the water outlet 17 toward the water inlet 16.

In practical application, the circulation assembly further comprises a second heater and a cooler, the second heater is arranged in the heating pipeline and used for heating the humidifying medium in the heating pipeline, and the cooler is arranged in the cooling pipeline and used for cooling the humidifying medium in the cooling pipeline.

Therefore, the humidifying medium with higher heating temperature by the heater and the humidifying medium with lower cooling temperature by the cooler are mixed in the water outlet pipeline, and the temperature of the humidifying medium in the heating pipeline and the temperature of the humidifying medium in the cooling pipeline can be adjusted, so that the temperature of the humidifying medium mixed in the water outlet pipeline can be adjusted.

Specifically, the cooler is a heat exchanger, that is, one side of the heat exchanger passes through cooling water, and the other side of the heat exchanger passes through a humidifying medium, so as to exchange heat and cool the humidifying medium.

In some embodiments, the circulation assembly further comprises a second temperature detector disposed in the outlet conduit for detecting the temperature of the humidification media within the outlet conduit.

Furthermore, the circulation assembly further comprises a cooling valve, the cooling valve is arranged on the cooling pipeline and connected with the second temperature detector, and the cooling valve is used for adjusting the on-off and the opening degree according to the detection result of the second temperature detector, so that the amount of the humidification medium with lower temperature output by the cooling pipeline is adjusted, and the temperature of the humidification medium in the water outlet pipeline is adjusted.

It should be noted that the first heater is used for heating the humidification medium entering the communication pipe to raise the temperature of the humidification medium sprayed into the spraying cavity 131 to be higher than the dew point temperature in the spraying cavity 131, so that the temperature regulation range is small, and the second heater is matched with the cooler to regulate the temperature of the humidification medium in the water outlet pipeline, so that the humidification medium can be subjected to temperature regulation in a large range.

In some embodiments, the humidification apparatus further comprises a third heater disposed at the bottom of the humidification tank 10 for heating the humidification medium in the bubbling chamber 132 to increase the temperature of the humidification medium accumulated at the bottom of the bubbling chamber 132, thereby increasing the temperature of the bubbled humidified gas.

Further, a third temperature detector is used for detecting the temperature of the humidification medium in the bubbling chamber 132, and is connected to a third heater, and the third heater heats the humidification medium in the bubbling chamber 132 according to the detection result of the third temperature detector.

It should be noted in connection with the above embodiments that the temperature detector cooperates with the heater and/or the cooler to ensure the accuracy of the temperature adjustment.

In addition, in order to realize the opening and closing of each pipeline, a corresponding valve may be provided in the pipeline for control.

In some embodiments, the humidifying device further comprises a liquid adding mechanism, wherein the liquid outlet end of the liquid adding mechanism is communicated with the water inlet 16 and is used for inputting the humidifying medium into the water inlet 16 so as to supplement the humidifying medium.

It can be understood that the humidifying medium in the humidifying chamber 13 can be recycled through the circulating component, but the humidified gas is discharged from the gas outlet 15, so that the total amount of the humidifying medium is still reduced, and the liquid adding mechanism can supplement the humidifying medium into the humidifying chamber 13 after the humidifying medium is reduced, so as to ensure the humidifying effect.

When the liquid level detector detects that the liquid level of the humidification medium accumulated in the bubbling chamber 132 is reduced to the lowest liquid level (the humidification effect is influenced by the fact that the liquid level of the humidification medium is lower than the lowest liquid level), the liquid adding mechanism inputs the humidification medium into the water inlet 16; when the liquid level detector detects that the liquid level of the humidification medium accumulated in the bubbling chamber 132 rises to the highest liquid level (the liquid level of the humidification medium is higher than the highest liquid level, which can cause liquid drops to be carried in the gas and affect the humidification effect), the liquid adding mechanism stops inputting the humidification medium.

Simultaneously, can also set up the siren among the humidification device, the siren is connected with the liquid level detector, and when the liquid level of humidification medium rose to the highest liquid level, the siren can send out the police dispatch newspaper to warn operating personnel, make things convenient for operating personnel to control humidification device.
