[0030] Reference below Figure 1-Figure 3 A filter device 100 for a vehicle according to an embodiment of the present invention is described.

[0031] Reference Figures 1 to 3 As shown, a vehicle filtering device 100 according to an embodiment of the present invention includes: an adsorbent 10 , a heating element 20 and an air compressor 30 .

[0032] The adsorbent 10 has an open port 11, a connecting port and a purge port. The open port 11 is used to guide air into the adsorbent 10. The adsorbent 10 is used to adsorb the target gas. The connecting port is used to connect to the battery stack 200 to guide the air after the adsorbed target gas enters the battery stack 200. The heating element 20 is configured to contact the adsorbent 10. The heating element 20 is used to heat the adsorbent 10 to desorb the target gas. The air compressor 30 has an air compressor outlet, and the air compressor outlet is connected to the purge port.

[0033] The filter device 100 has a setting mode. When the filter device 100 is in the setting mode, the air compressor 30 works to guide air from the purge port to the open port 11 , and the heater 20 heats the adsorption element 10 to discharge the target gas.

[0034] Among them, an open port 11 is provided on the adsorbent 10, and the open port 11 is open to the space outside the adsorbent 10, for example, the open port 11 is open to the atmospheric environment, and air enters the adsorbent 10 through the open port 11. The composition of the air is relatively complex and may contain gases that have a negative impact on the battery stack 200. The adsorbent 10 is used to adsorb the target gas. For example, an adsorbent is provided in the adsorbent 10, and the adsorbent adsorbs the target gas. The target gas is a gas that is harmful to the battery stack 200, such as SO2, NH3, NO2, etc. The connecting port on the adsorbent 10 is connected to the battery stack 200, and the air after the target gas is adsorbed enters the battery stack 200 through the connecting port, so that the battery stack 200 works normally.

[0035] The heating element 20 is arranged to contact the adsorption element 10 , and the heating element 20 heats the adsorption element 10 , so that the target gas is out of the adsorption state.

[0036] In the related art, the filter element assembly of the air filter in a hydrogen fuel vehicle adopts a multi-layer composite structure. This structure stacks a gas adsorption layer and a gas filtration layer together to achieve the effects of filtering and adsorption. The adsorption capacity of this structure is limited. After working for a period of time, the filter element assembly cannot work normally. In the related art, the temperature of the filter element assembly is usually heated to desorb the harmful gases adsorbed by the filter element assembly, but the desorption efficiency of the above scheme is low.

[0037] In the embodiment of the utility model, an air compressor 30 is provided, and the outlet of the air compressor is connected to the purge port. The air compressor 30 supplies flowing gas to the adsorbent 10 through the purge port, and the heating element 20 heats the adsorbent 10 to make the target gas leave the adsorbed state, and the flowing gas drives the target gas leaving the adsorbed state to flow, thereby reducing the concentration of the target gas in the adsorbent 10. The flowing gas can drive the target gas leaving the adsorbed state to the space outside the adsorbent 10, or it can disturb the air of the adsorbent 10. The target gas flows from the area around the adsorbed substance to the area far away from the adsorbed substance, making the target gas more uniform, thereby improving the desorption efficiency of the target gas.

[0038] At the same time, it can be understood that the flowing gas blowing through the adsorbent can also disturb the adsorbed more stubborn target gas, thereby allowing more target gas to be desorbed from the adsorbent, thereby improving the cleanliness of the adsorbent 10.

[0039] The flowing gas drives the target gas in the adsorbed state to the space outside the adsorbent 10 , which can better increase the service life of the adsorbent 10 .

[0040] The air compressor 30 can directly extract air from the atmosphere and guide it to the adsorbent 10, or it can discharge the air processed by the adsorbent 10 to the adsorbent 10 in reverse. For example, there are multiple adsorbents 10, and the air compressor 30 discharges the air processed by the first adsorbent 10 to the second adsorbent 10.

[0041] According to the vehicle filtering device 100 of the embodiment of the utility model, an air compressor 30 is arranged at the purge port, and the air compressor 30 supplies flowing gas to the adsorbent 10 through the purge port, and the heating element 20 heats the adsorbent 10 to make the target gas leave the adsorbed state, and the flowing gas drives the target gas leaving the adsorbed state, thereby reducing the concentration of the target gas in the adsorbent 10, thereby improving the desorption efficiency of the target gas, and the target gas is separated from the adsorbed substance more quickly, which can also further increase the service life and cleanliness of the adsorbent 10.

[0042] Reference Figures 1 to 3 As shown, in some embodiments, there are multiple adsorbents 10, and the air compressor 30 also has an air compressor inlet 31. The corresponding connecting ports of the multiple adsorbents 10 are respectively connected to the air compressor inlet 31. The multiple adsorbents 10 include a first adsorbent 14 and a second adsorbent 15. The first adsorbent 14 is provided with a first purge port 141 connected to the air compressor outlet, and the second adsorbent 15 is provided with a second purge port 151 connected to the air compressor outlet.

[0043] In which, the filter device 100 is in the setting mode, and the air compressor 30 guides the air adsorbed by the first adsorbent 14 to be discharged back to the second adsorbent 15 through the second purge port 151; or, the air compressor 30 guides the air adsorbed by the second adsorbent 15 to be discharged back to the first adsorbent 14 through the first purge port 141.

[0044] Reference Figures 1 to 3 As shown, the first adsorbent 14 and the second adsorbent 15 are arranged in parallel, and the first adsorbent 14 and the second adsorbent 15 can work simultaneously to adsorb harmful gases, or one of them can work while the other is suspended or purged by the air compressor 30. For example, the first adsorbent 10 works to adsorb the target gas, and the air after the target gas is adsorbed is discharged to the air compressor 30, and then guided to the second adsorbent 10, and the second adsorbent 10 is cleaned through the purge port of the second adsorbent 10.

[0045] It should be noted that even if the multiple adsorbents 10 always work synchronously, the states of the adsorbents 10 may be different due to interference from various factors. For example, the difference in installation distance may cause some of the adsorbents 10 to fully adsorb the target gas earlier.

[0046] In the above scheme, by setting up multiple adsorbents 10, multiple adsorbents 10 can work simultaneously or partially, so that the filtering device 100 can adapt to a wider range of needs and match more application scenarios. At the same time, an air compressor inlet 31 is set to connect the connecting ports of multiple adsorbents 10, and the treated air is discharged back into the adsorbent 10. The treated air is cleaner, which improves the cleaning effect of the adsorbent 10.

[0047] Reference Figures 1 to 3 As shown, for example, the first adsorbent 14 works to adsorb the target gas, and the air processed by the first adsorbent 14 is discharged to the air compressor inlet 31 through the connecting port, and the air compressor 30 guides the processed air to the second purge port 151, and the cleaner air purges the adsorbed material in the second adsorbent 15; or, the second adsorbent 15 works to adsorb the target gas, and the air processed by the second adsorbent 15 is discharged to the air compressor inlet 31 through the connecting port, and the air compressor 30 guides the processed air to the first purge port 141, and the cleaner air purges the adsorbed material in the first adsorbent 14.

[0048] Reference Figures 1 to 3 As shown, in some embodiments, the air compressor outlet is connected to the first purge port 141 through a first pipe 321, and a first switch valve 322 is provided on the first pipe 321. The air compressor outlet is connected to the second purge port 151 through a second pipe 323, and a second switch valve 324 is provided on the second pipe 323; wherein, the filter device 100 is in a setting mode, and one of the first switch valve 322 and the second switch valve 324 is working.

[0049] Among them, a first pipeline 321 is arranged between the air compressor outlet and the first purge port 141, and a first switch valve 322 is arranged on the first pipeline 321. The first switch valve 322 controls the on-off of the first pipeline 321, so that the first pipeline 321 switches between the two states of passage and disconnection; a second pipeline 323 is arranged between the air compressor outlet and the second purge port 151, and a second switch valve 324 is arranged on the second pipeline 323. The second switch valve 324 controls the on-off of the second pipeline 323, so that the second pipeline 323 switches between the two states of passage and disconnection.

[0050] In the above scheme, the first switch valve 322 and the second switch valve 324 control the on / off of the air compressor 30 and the first adsorbent 14 and the second adsorbent 15 to avoid the air from being misguided, thereby improving the safety and reliability of the filter device 100.

[0051] For example, the first adsorbent 14 works to adsorb the target gas, and the air processed by the first adsorbent 14 is discharged to the air compressor inlet 31 through the connecting port, the second switch valve 324 works to make the second pipeline 323 in a passage state, and the air compressor 30 guides the treated air to the second purge port 151, and the cleaner air purges the adsorbed material in the second adsorbent 15; or, the second adsorbent 15 works to adsorb the target gas, and the air processed by the second adsorbent 15 is discharged to the air compressor inlet 31 through the connecting port, the first switch valve 322 works to make the first pipeline 321 in a passage state, and the air compressor 30 guides the treated air to the first purge port 141, and the cleaner air purges the adsorbed material in the first adsorbent 14.

[0052] Reference Figures 1 to 3 As shown, in some embodiments, the air compressor 30 also has an air compressor inlet 31, the first adsorption component 14 is provided with a first connecting port 142, the second adsorption component 15 is provided with a second connecting port 152, the air compressor inlet 31 is connected with the first connecting port 142 through a third pipe 311, the air compressor inlet 31 is connected with the second connecting port 152 through a fourth pipe 312, the third pipe 311 is provided with a first on-off valve 313, and the fourth pipe 312 is provided with a second on-off valve 314.

[0053] Among them, a third pipeline 311 is arranged between the air compressor inlet 31 and the first connecting port 142, and a first on-off valve 313 is arranged on the third pipeline 311. The first on-off valve 313 controls the on-off of the third pipeline 311, so that the third pipeline 311 switches between the two states of passage and disconnection; a fourth pipeline 312 is arranged between the air compressor inlet 31 and the second connecting port 152, and a second on-off valve 314 is arranged on the fourth pipeline 312. The second on-off valve 314 controls the on-off of the fourth pipeline 312, so that the fourth pipeline 312 switches between the two states of passage and disconnection.

[0054] In the above scheme, the first on-off valve 313 and the second on-off valve 314 control the on-off of the air compressor 30 and the first adsorbent 14 and the second adsorbent 15 to avoid the air from being misguided, thereby improving the safety and reliability of the filter device 100.

[0055] For example, the first adsorbent 14 works to adsorb the target gas, the first on-off valve 313 works to make the third pipeline 311 in a passage state, the air processed by the first adsorbent 14 is discharged to the air compressor inlet 31 through the first connecting port 142, the air compressor 30 guides the processed air to the second purge port 151, and the cleaner air purges the adsorbed material in the second adsorbent 15; or, the second adsorbent 15 works to adsorb the target gas, the second on-off valve 314 works to make the fourth pipeline 312 in a passage state, the air processed by the second adsorbent 15 is discharged to the air compressor inlet 31 through the second connecting port 152, the air compressor 30 guides the processed air to the first purge port 141, and the cleaner air purges the adsorbed material in the first adsorbent 14.

[0056] In some embodiments, an adsorption space is provided in the adsorption element 10, and activated carbon and / or zeolite are provided in the adsorption space.

[0057] Among them, activated carbon is a porous adsorbent with a large surface area and rich pore structure. Zeolite is an adsorbent with a regular pore structure that can selectively adsorb molecules according to their size and polarity.

[0058] In the above scheme, the adsorption space is provided with at least activated carbon and / or zeolite, that is, the adsorbent includes activated carbon and zeolite, and the properties of activated carbon and zeolite are utilized to treat the target gas, thereby better adsorbing the target gas and improving the adsorption efficiency.

[0059] For example, the adsorption space is provided with activated carbon alone; or, the adsorption space is provided with zeolite alone; or, the adsorption space is provided with activated carbon and zeolite.

[0060] In some embodiments, zeolite is provided in the adsorption space, and the zeolite structure is one or more of Y-type zeolite, β-type zeolite, and ZSM-5 type zeolite.

[0061] Among them, Y-type zeolite is a zeolite with a three-dimensional channel network. Its crystal structure is composed of alternating silicon-oxygen tetrahedrons and aluminum-oxygen tetrahedrons. The pores of Y-type zeolite are usually around 12 angstroms, which can accommodate larger molecules to enter the pores. Y-type zeolite has good thermal stability and chemical stability and can maintain its structural stability at higher temperatures. β-type zeolite is a special type of zeolite, a porous structure material composed of silicate minerals. Its pore size is larger, usually between 6-7 angstroms. The relatively large pore size makes β-type zeolite have unique properties in the adsorption and separation process. ZSM-5 zeolite has unique structural characteristics, including microporous and mesoporous structures. Its pore size is about 0.5-0.7 nanometers and its specific surface area is large. ZSM-5 zeolite has significant selectivity in adsorption, separation and catalysis, and is suitable for the separation and conversion reactions of compounds with similar molecular sizes.

[0062] In the above scheme, the zeolite structure is one or more of Y-type zeolite, β-type zeolite, and ZSM-5 zeolite. The properties of Y-type zeolite, β-type zeolite, and ZSM-5 zeolite are used to adsorb the target gas, which is more targeted and further improves the adsorption effect.

[0063] For example, the zeolite structure is Y-type zeolite; or, the zeolite structure is β-type zeolite; or, the zeolite structure is ZSM-5 type zeolite; or, the zeolite structure is Y-type zeolite and β-type zeolite; or, the zeolite structure is Y-type zeolite and ZSM-5 type zeolite; or, the zeolite structure is β-type zeolite and ZSM-5 type zeolite; or, the zeolite structure is Y-type zeolite, β-type zeolite, and ZSM-5 type zeolite.

[0064] Reference Figures 1 to 3 As shown, in other embodiments, the connecting port is provided with an air filter element 50, and the air filter element 50 is provided with filter paper.

[0065] Among them, the filter paper has a filtering function. The filter paper can filter dust, thereby further purifying the air and avoiding interference with the normal operation of the battery stack 200.

[0066] In some other embodiments, the zeolite structure is one or more of Y-type zeolite, β-type zeolite, and ZSM-5 type zeolite, and the connecting port is provided with an air filter element 50, and the air filter element 50 is provided with filter paper.

[0067] Among them, Y-type zeolite is a zeolite with a three-dimensional channel network. Its crystal structure is composed of alternating silicon-oxygen tetrahedrons and aluminum-oxygen tetrahedrons. The pores of Y-type zeolite are usually around 12 angstroms, which can accommodate larger molecules to enter the pores. Y-type zeolite has good thermal stability and chemical stability and can maintain its structural stability at higher temperatures. β-type zeolite is a special type of zeolite, a porous structure material composed of silicate minerals.

ZSM-5 zeolite has unique structural characteristics, including microporous and mesoporous structures, with a pore size of about 0.5-0.7 nanometers and a large specific surface area. ZSM-5 zeolite has significant selectivity in adsorption, separation and catalysis, and is suitable for the separation and conversion reactions of compounds with similar molecular sizes. Filter paper has a filtering function, and filter paper can filter dust, thereby further purifying the air to avoid interference with the normal operation of the battery stack 200.

[0068] In the above scheme, the zeolite structure is one or more of Y-type zeolite, β-type zeolite, and ZSM-5 type zeolite. The properties of Y-type zeolite, β-type zeolite, and ZSM-5 type zeolite are used to adsorb the target gas, which is more targeted, thereby further improving the adsorption effect. In addition, an air filter 50 with filter paper is provided at the same time, and the filter paper filters dust. The two cooperate to achieve better treatment of air.

[0069] Reference Figures 1 to 3 As shown, in some embodiments, the battery stack 200 is disposed downstream of the air compressor 30 .

[0070] Among them, the battery stack 200 is arranged downstream of the air compressor 30, that is, the battery stack 200 is connected to the air compressor outlet. The air compressor 30 can not only discharge the treated air back to the adsorption element 10, but also discharge the treated air into the battery stack 200 to supply clean air for the battery stack 200.

[0071] The air compressor 30 may discharge all the processed air into the adsorption element 10 , or may discharge part of the processed air into the adsorption element 10 and discharge the other part of the processed air into the battery stack 200 .

[0072] In the above scheme, the battery stack 200 is arranged downstream of the air compressor 30. The air compressor 30 can not only discharge the treated air back to the adsorption element 10 to clean the adsorption element 10, but also discharge the treated air to the battery stack 200 to supply air for the battery stack 200. The air compressor 30 plays multiple roles and improves utilization.

[0073] Reference Figures 1 to 3 As shown, in some embodiments, the filter device 100 further includes: a control component 40, which is electrically connected to the air compressor 30. When the target gas adsorbed by the adsorption component 10 reaches a rated adsorption threshold, the filter device 100 switches to a set mode.

[0074] The rated adsorption threshold is a parameter compiled through relevant calibration tests. After the target gas adsorbed by the adsorption element 10 reaches the rated adsorption threshold, the adsorption element 10 cannot continue to adsorb the target gas.

[0075] In the above solution, the rated adsorption threshold is set as a reference value to start the air compressor 30, which increases controllability, reduces the probability that the filter device 100 cannot achieve filtering, and increases the reliability of the filter device 100.

[0076] For example, the rated adsorption threshold is the working time, and the working time of the adsorbent 10 is used as a parameter to measure the amount of target gas adsorbed by the adsorbent 10; or, the rated adsorption threshold is set to the concentration change value of the target gas before and after the adsorbent 10, and the concentration change value is 0, which means that the adsorbent 10 cannot adsorb the target gas.

[0077] Reference Figures 1 to 3 As shown, in some embodiments, an installation space is provided in the adsorption member 10, and the heating member 20 is provided in the installation space.

[0078] Among them, an installation space is provided in the adsorption component 10, and the installation space is used to install the heating component 20. That is to say, the heating component 20 is installed in the adsorption component 10 to reduce the heat loss of the heating component 20, so that the heat generated by the heating component 20 is concentrated on the adsorption component 10, thereby improving the utilization rate.

[0079] In the above solution, by installing the heating element 20 in the adsorption element 10, the heat generated by the heating element 20 is concentrated on the adsorption element 10, thereby reducing heat loss and improving energy utilization.

[0080] In some embodiments, the heating element 20 is attached to the surface of the adsorption element 10, which reduces the difficulty of assembly.

[0081] In some specific embodiments, the heating element 20 is constructed as an electric heating element, and the adsorption element 10 is heated by electric heating, which is convenient to use.

[0082] Specifically, the heating element 20 is constructed as a PTC heating element, which generates heat by utilizing the characteristics of the PTC material.
