[0044] Referring to Figure 1 , Figure 2 and Figure 3 , Figure 1 is a structural schematic diagram of a gas purification device 10 provided by an embodiment of the present application, Figure 2 is Figure 1 a sectional view of the first end portion 140 of the gas purification device 10 in Figure 3 is Figure 1 a structural schematic diagram of the cooling cavity 111 and the layered partition plate 200 in Figure 4 is Figure 3 an internal structural schematic diagram of the layered partition plate 200 in the removal portion. The gas purification device 10 provided by an embodiment of the present application includes a shell 100, a layered partition plate 200 and a function division plate 300.

[0045] The shell 100 has a containing cavity 110, and the shell 100 is further provided with an air inlet pipe 120 and an air outlet pipe 130, the air inlet pipe 120 is used for introducing the gas to be purified, and the air outlet pipe 130 is used for discharging the purified gas. It should be noted that the gas to be purified can be hydrogen to be purified, helium to be purified and other gases, and the present application takes the purified hydrogen as an example for description.

[0046] The layered partition plate 200 is arranged in the containing cavity 110, and the layered partition plate 200 divides the containing cavity 110 into a cooling cavity 111 and a composite cavity 112 along a first direction a. The cooling cavity 111 is in communication with the air inlet pipe 120, and the cooling cavity 111 is used for cooling the gas to be purified. It should be noted that the hydrogen is usually prepared by hydrolysis to prepare hydrogen as the hydrogen source of the fuel cell, but the hydrolysis reaction is an exothermic reaction, so that the temperature of the generated hydrogen is relatively high, which is not suitable for direct supply into the fuel cell, and the generated hydrogen needs to be cooled first.

[0047] The functional division plate 300 is arranged in the composite cavity 112, and the functional division plate 300 divides the composite cavity 112 into a filter cavity 1121 and an adsorption cavity along a second direction b. The filter cavity 1121 is in communication with the cooling cavity 111. In the specific arrangement, the layered partition plate 200 is provided with a first through hole 210 in communication with the filter cavity 1121. Through the above arrangement, the cooled hydrogen to be purified enters the filter cavity 1121 through the first through hole 210. The functional division plate 300 is used for filtering the gas to be purified in the filter cavity 1121, and the adsorption cavity is used for adsorbing the impurities of the gas to be purified passing through the functional division plate 300. The adsorption cavity is also in communication with the air outlet pipe 130, and the second direction b is perpendicular to the first direction a.

[0048] The above-mentioned gas purification device 10 realizes the functional division of the limited containing cavity 110 by arranging the layered partition plate 200 and the functional division plate 300, and divides the containing cavity 110 into the cooling cavity 111, the filter cavity 1121 and the adsorption cavity, so as to realize the cooling, filtering and adsorption of the gas to be purified. The space is fully utilized while the purification effect is ensured, the integration degree is high, the volume of the gas purification device 10 is reduced as much as possible, and the gas purification device 10 can be applied to the equipment with compact space such as the submersible 20, so as to meet the gas supply demand of the rear-end fuel cell system of the submersible.

[0049] To further ensure the purification effect, a preferred embodiment comprises a functional partitioning plate 300 comprising a filter plate 310 and an adsorption partition plate 320, spaced apart along the second direction b within the composite chamber 112. The filter plate 310 and the adsorption partition plate 320 divide the composite chamber 112 along the second direction b into a filter chamber 1121, a first adsorption zone 1122, and a second adsorption zone 1123. The filter plate 310 is used to filter the gas to be purified in the filter chamber 1121, the first adsorption zone 1122 is used to adsorb impurities from the gas to be purified that passes through the filter plate 310, and the second adsorption zone 1123 is used to adsorb impurities from the gas to be purified that passes through the adsorption partition plate 320. In a specific configuration, the second adsorption zone 1123 is connected to the gas outlet pipe 130. With this configuration, the gas to be purified, after being cooled in the cooling chamber 111, enters the filter chamber 1121 through the first through hole 210, is filtered by the filter plate 310, and then sequentially enters the first adsorption zone 1122 and the second adsorption zone 1123 for adsorption before being discharged.

[0050] To facilitate adsorption of the gas to be purified by the first adsorption zone 1122 and the second adsorption zone 1123, a first adsorbent and a second adsorbent are respectively filled in the first adsorption zone 1122 and the second adsorption zone 1123. In a specific configuration, the first adsorbent and the second adsorbent can be made of the same or different adsorbent materials. Furthermore, the first adsorbent and / or the second adsorbent can be a mixture of multiple adsorbent materials depending on the impurities in the gas to be purified. The adsorbent materials may include silica gel, molecular sieves, activated carbon, deionized resins, and the like.

[0051] Combine Figure 5 As shown, Figure 5 for Figure 4 Schematic diagram of the structure of the second end portion 150 in FIG. To facilitate filling the first adsorption zone 1122 and the second adsorption zone 1123 with adsorption material, the housing 100 is configured to include a first end portion 140 and a second end portion 150 distributed along a third direction c. The first end portion 140 and the second end portion 150 are respectively provided with a first filling port 141 and a second filling port 151 communicating with the first adsorption zone 1122 and the second adsorption zone 1123. The first end portion 140 and the second end portion 150 are preferably arc-shaped plates, and the third direction c, the second direction b, and the first direction a are perpendicular to each other.

[0052] Combine Figure 6 As shown, Figure 6The flow schematic of the to-be-purified gas in the composite cavity 112 is provided for an embodiment of the present application. In order to sufficiently filter and adsorb the impurities of the to-be-purified gas, specifically, the filter plate 310 is connected with the first end portion 140 and the second end portion 150 respectively, and the filter plate 310 is provided with a filter screen, one end of the adsorption partition plate 320 is connected with the first end portion 140, and the other end of the adsorption partition plate 320 has a first gap 330 with the second end portion 150, and the filter screen and the first gap 330 are distributed at both ends of the third direction c. Through the above setting, the to-be-purified gas entering the adsorption stage through the filter screen will flow through the first adsorption area 1122 and the second adsorption area 1123 in S shape, and finally flow out from the gas outlet pipe 130, thereby completing the purification process of the gas. The S-shaped flow direction of the to-be-purified gas ensures that the to-be-purified gas is fully operated in the filter plate 310 and the adsorption area.

[0053] It should be noted that the to-be-purified gas cooled in the cooling cavity 111 is easy to be liquefied in this stage. In order to prevent the gas from flowing into the filter cavity 1121 through the first through hole 210 after being liquefied, thereby affecting the normal filtering operation, specifically, the functional division plate 300 further includes a liquid storage partition plate 340, the liquid storage partition plate 340 is arranged on the side of the filter plate 310 away from the adsorption partition plate 320, the filter cavity 1121 is formed between the liquid storage partition plate 340 and the filter plate 310, the side of the liquid storage partition plate 340 away from the filter plate 310 forms a liquid storage cavity 1124 with the shell 100, the liquid storage cavity 1124 is connected with the cooling cavity 111, and in the specific arrangement, the second through hole 220 is further arranged on the layered partition plate 200 and is connected with the liquid storage cavity 1124, so that the gas can flow into the liquid storage cavity 1124 through the second through hole 220 after being liquefied, and the liquid storage cavity 1124 is used for storing the to-be-purified gas cooled into liquid state.

[0054] To ensure that the cooling of the liquid to be purified gas can be preferentially through the second through hole 220 into the liquid storage chamber 1124, more specifically, the gas purification device 10 also includes a plurality of cooling flow guide assembly 400 arranged in the third direction c in the cooling chamber 111, a plurality of cooling flow guide assembly 400 divides the cooling chamber 111 into a plurality of first cooling zone 1111, a plurality of first cooling zone 1111 is respectively communicated with the liquid storage chamber 1124, in the specific setting, each first cooling zone 1111 has a second through hole 220 opened in the layered partition plate 200. And a plurality of first cooling zone 1111 through the opening of cooling flow guide assembly 400 are communicated with each other, a plurality of first cooling zone 1111 also has the gas inlet cooling zone 1111a and the filter cooling zone 1111b distributed at both ends of the third direction c, the gas inlet cooling zone 1111a is communicated with the gas inlet pipe 120, and the filter cooling zone 1111b is communicated with the filter chamber 1121. Through the above setting, after the purified gas enters the gas inlet cooling zone 1111a from the gas inlet pipe 120, it will reach the filter cooling zone 1111b after passing through a plurality of first cooling zone 1111, and enter the filter chamber 1121 from the first through hole 210 on the filter cooling zone 1111b, which ensures that the purified gas can be liquefied and enter the liquid storage chamber 1124 through the second through hole 220 in the gas inlet cooling zone 1111a and the first cooling zone 1111.

[0055] In combination Figure 7 As shown, Figure 7 The flow diagram of the purified gas in the cooling chamber 111 provided by an embodiment of the present application. In order to better cool and guide the purified gas, further, the shell 100 has a first side wall 160 and a second side wall 170 distributed along the second direction b, the cooling flow guide assembly 400 includes first cooling flow guide plate 410 and second cooling flow guide plate 420 staggered and spaced apart along the third direction c, one end of the first cooling flow guide plate 410 is connected with the first side wall 160, the other end of the first cooling flow guide plate 410 has a second gap with the second side wall 170, one end of the second cooling flow guide plate 420 is connected with the second side wall 170, the other end of the second cooling flow guide plate 420 has a third gap with the first side wall 160. In the specific setting, the first cooling flow guide plate 410 and the second cooling flow guide plate 420 in the same cooling flow guide assembly 400 form a second cooling zone 1112, each second cooling zone 1112 has a second through hole 220 opened in the layered partition plate 200.

[0056] Through the above setting, the warm gas generated by hydrolysis hydrogen production enters the cooling cavity 111 through the gas inlet pipe 120, and under the flow guide loop formed by the first cooling guide plate 410 and the second cooling guide plate 420, the purified gas flows in an S shape, part of the purified gas is condensed in this process, and flows to the second through hole 220 along the layered partition plate 200 under the action of gravity, and then enters the liquid storage cavity 1124 at the edge of the shell 100, realizing the cooling of the purified gas and the collection of the condensed liquid.

[0057] As shown in Figure 8 and Figure 9 , Figure 8 is a schematic view of a structure of a gas purification device 10 provided by an embodiment of the application installed on a submarine 20, Figure 9 is another schematic view of a structure of a gas purification device 10 provided by an embodiment of the application installed on a submarine 20. In order to more conveniently install the gas purification device 10 on the submarine 20 having a containing cavity, a preferred embodiment has a cooling wall 180 in the shell 100 which is adapted to the inner wall of the containing cavity, and the cooling cavity 111 is formed between the cooling wall 180 and the layered partition plate 200. In a specific setting, the cooling wall 180 is preferably an arc-shaped plate to facilitate adaptation to the inner wall of the containing cavity, but is not limited to the above-mentioned arc-shaped plate, and any shape which can be adapted to the shape of the inner wall can be used. When installed, the cooling wall 180 and the inner wall of the containing cavity are filled with a heat-conducting silicone grease, but the heat-conducting silicone grease is not limited, and other heat-conducting materials can be used, so that the temperature of the wall of the submarine 20 is conducted to the cooling wall 180.

[0058] Through the above setting, when the submarine 20 is used underwater, the gas generated by hydrolysis hydrogen production is introduced into the cooling cavity 111 through the gas inlet pipe 120, and the low-temperature (about 4-10℃) seawater environment underwater is transmitted to the cooling wall 180 through the inner wall of the containing cavity, so that the cooling wall 180 cools the purified gas in the cooling cavity 111, avoiding the current cooling mode using additional equipment such as a heat exchange device, and reducing power consumption and the structure of the gas purification device 10.

[0059] It should be noted that the containing cavity of the submarine 20 is generally used to install a gas cylinder 21 and / or other first equipment 22, and neither the gas cylinder 21 nor the first equipment 22 is completely fitted to the inner wall of the containing cavity, and there is a containing gap 23 between them. The gas purification device 10 designed by the application has a small volume and can be completely installed in the containing gap 23. By using the containing gap 23 of the underwater unmanned submarine 20, the gas obtained by hydrolysis hydrogen production is purified, and the control of the overall volume and complexity of the system is also considered.

[0060] As shown in Figure 10 , Figure 10The structure schematic diagram of the gas purification device 10 provided by an embodiment of the present application matches the rib plate of the submarine 20, it is to be explained that the inner wall of the containing cavity can also be provided with reinforcing ribs or rib plates, and the rib plate is taken as an example for description, at this time, the shape of the cooling wall 180 is designed according to the rib plate structure of the inner wall surface of the containing cavity in the submarine 20, so that the maximum conformal matching between the cooling wall 180 and the rib plate is realized.

[0061] In the specific arrangement, the shell 100 also has a bottom plate 190 away from one side of the layered partition plate 200, a composite cavity 112 is formed between the bottom plate 190 and the layered partition plate 200, and the bottom plate 190 is preferably arc-shaped but is not limited to arc-shaped, and is specifically designed according to the available containing gap 23, a certain installation gap is reserved, and the arc surface size is designed on the basis of considering the pressure bearing structure. The whole shell 100 can be arranged in a narrow space, the space utilization rate of the submarine 20 is improved, and meanwhile, the shell 100 has strong pressure bearing capacity and can meet the gas supply demand of the rear-end fuel cell system.

[0062] In the specific installation, in the submarine 20, the number of the gas purification device 10 can be multiple, and the multiple gas purification devices 10 are installed at intervals to the side of the submarine 20, at this time, the liquid storage separation plate 340, the filter plate 310 and the adsorption separation plate 320 in the gas purification device 10 are preferably one. The number of the gas purification device 10 can be one, and one gas purification device 10 is arranged on the fuel cell power cylinder 21 in the submarine 20, and the containing gap 23 is in a crescent shape.
