In actual use, the adsorption structure 1 may be selected from several stages of adsorption units 11 according to actual conditions. In the embodiment shown in fig. 1, the adsorption structure 1 of the present invention is composed of two stages of adsorption units 11, but the present invention is not limited thereto.
In the first aspect, the single adsorption unit 11 includes a first adsorption part 111, a second adsorption part 112, and a third adsorption part 113 that penetrate end to end. In the adsorption process, each adsorption unit 11 is first subjected to a first adsorption process by the first adsorption unit 111, then subjected to a second adsorption process by the second adsorption unit 112, and finally subjected to a third adsorption process by the third adsorption unit 113. So can show through the mode of adsorbing many times and increase waste gas adsorption effect, especially can adsorb the processing to large capacity waste gas.
The first adsorption part 111 and the third adsorption part 113 have the same structure. Wherein the first adsorption part 111 comprises a first chamber 114 and a first adsorbent. Specifically, a first adsorbent is provided in the first chamber 114, the first adsorbent has a plurality of flow channels 1151 for gas to flow, and an adsorbent component for exhaust gas is provided on the surface of the flow channel 1151, so that the gas is divided into a plurality of gas flows when passing through the first adsorption part 111, and the gas is adsorbed in the plurality of flow channels 1151 of the first adsorbent, and at this time, a large-capacity gas is divided into a plurality of small-capacity gases, and the small-capacity gases can sufficiently ensure the contact area between the gas and the adsorbent component. Since the structure of the third adsorption part 113 is the same as that of the first adsorption part 111, the structure of the third adsorption part 113 according to the present invention is not described herein again.
The second adsorption part 112 includes a second cavity 1121 and a second adsorbent, the second adsorbent includes an adsorption plate 1122, the adsorption plate 1122 is disposed on the inner wall of the second cavity 1121, and the surface of the adsorption plate 1122 is provided with an adsorbent component for the exhaust gas, so that when passing through the second adsorption part 112, the multiple air flows are converged at the second adsorption part 112, and the gas is adsorbed by the adsorption plate 1122.
To sum up, gas divides into the stranded air current when first adsorption part 111 and carries out the first adsorption treatment in a plurality of runners 1151 of first adsorption body, then the stranded air current assembles at second adsorption part 112 and carries out the second adsorption treatment, and the gas after the second adsorption treatment that will divide into the stranded air current by third adsorption part 113 again at last carries out the third adsorption treatment, uses the mode of multistage absorption to improve the adsorption effect greatly.
Since the plurality of gases are already gathered into one gas stream in the second adsorption part 112, the gas volume is large at this time, and the large gas volume may not be sufficiently in contact with the adsorption plate 1122, especially the gas in the center of the gas stream. Therefore, the present invention provides the microporous structural body 2 in the second cavity 1121, the microporous structural body 2 includes at least one microporous stirring unit 21, and the at least one microporous stirring unit 21 is provided in the second cavity 1121. The gas can be sufficiently stirred when passing through the fine hole stirring unit 21, particularly the gas in the center of the gas flow.
Specifically, the micropore stirring unit 21 includes the stirring body 211, and the stirring body 211 is disposed to contact the adsorption plate 1122 on the one side of the second cavity 1121 with the adsorption plate 1122 on the other side of the second cavity 1121 at a predetermined angle with respect to the direction of gas flow. For example, as shown in fig. 2, the stirring body 211 is vertically disposed between the second cavities 1121.
There is also a stirring body 211 having a plurality of stirring minute holes 2111, and all surfaces of the single stirring body 211 including the surfaces of the stirring minute holes 2111 are provided with an adsorbent component for exhaust gas. The gas flow forms bubbles when passing through the stirring micropores 2111 of the stirring body 211, and the surface area of the bubbles is increased when the bubbles are broken, which is equivalent to stirring and mixing the gas, so that the gas can be sufficiently contacted with the adsorbent component, and the adsorption effect is remarkably improved.
The adsorbent component on the surface of flow channel 1151, the adsorbent component on the surface of adsorption plate 1122, and the adsorbent component on the surface of stirring body 211 may be the same or different, and the present invention is not limited thereto.
The flow channel 1151 includes a first flat plate portion 1151a and a second flat plate portion 1151b, and the first flat plate portion 1151a and the second flat plate portion 1151b are symmetrically disposed and both are provided with an adsorbent component for the exhaust gas on the surface thereof. When the gas passes through the flow path 1151, the gas is subjected to adsorption treatment by the adsorbent component on the first flat plate portion 1151a and the adsorbent component on the second flat plate portion 1151 b.
When the gas flows in the flow channel 1151, the gas on both sides of the gas flow can be sufficiently contacted with the adsorbent component on the first flat plate portion 1151a and the adsorbent component on the second flat plate portion 1151b, respectively, but the gas in the center portion of the gas flow hardly comes into sufficient contact with the adsorbent components of the first flat plate portion 1151a and the second flat plate portion 1151 b. Therefore, the present invention further includes a guide structure 3, the guide structure 3 is provided in the plurality of flow channels 1151 of the first adsorbent, and the gas is guided to flow in the flow channels 1151 by using the guide structure 3.

The gas passing through the center portion of the gas flow path in the flow path 1151 is thus agitated (stirred) by the first meandering guide 311 and the second meandering guide 312, so that the gas in the center portion of the gas flow can sufficiently contact the adsorbent components in the first flat plate portion 1151a and the second flat plate portion 1151 b.
Further, the first meandering guide 311 and the second meandering guide 312 have the same structure, and each structure thereof includes a first meandering portion 313 and a second meandering portion 314 having an included angle, which is configured as a fixed angle.

Also, the second meandering guide 314 of the first meandering guide 311 and the second meandering guide 314 of the second meandering guide 312 may be bent in opposite directions. When the gas flows through the flow channel 1151, the first meandering portion 313 breaks up the gas at the center of the gas flow so that the gas flows to both sides of the first meandering portion 313, and the broken-up gas is guided in the direction of the first flat plate portion 1151a or the second flat plate portion 1151b by the second meandering portion 314, so that the gas at the center of the gas flow can be brought into sufficient contact with the adsorbent components on the first flat plate portion 1151a or the second flat plate portion 1151 b.
