[0038] The air inlet and outlet of the housing 1 are respectively provided with an air inlet shell 2 and an air outlet shell 5. It should be noted that the inner diameters of the air inlet shell 2 and the air outlet shell 5 gradually increase from one end toward the housing 1 along the length direction of the housing 1;

[0039] The support frame is installed in the middle of the housing 1. The upper and lower parts of the support frame are both provided with adsorption components for filtering the exhaust gas in the exhaust gas treatment state. The number of adsorption components in the upper and lower parts of the support frame is at least two, and the support frame and the adsorption components cooperate to set at least two exhaust gas filtering channels when in use.

[0040] The baffle is arranged on the inner side of the shell 1 and is located at the air inlet of the shell 1, and is slidably connected to the support frame, and is used to block the air inlet of an exhaust gas filter channel when replacing the adsorption component;

[0041] The exhaust fan 19 is installed at the end of the air outlet housing 5 and is used to extract air from the inside of the housing 1 when in use, so that a negative pressure is generated inside the housing 1 and the flow speed of the exhaust gas is increased;

[0042] There are multiple mounting holes 6, and the multiple mounting holes 6 are respectively arranged on both sides of the shell 1 and located at the end of the adsorption assembly, and the number of mounting holes 6 corresponds to the number of the end of the adsorption assembly. It should be noted that the adsorption assembly is placed on the support frame through the mounting hole 6. When the adsorption assembly and the support frame are installed in coordination, the end of the adsorption assembly is accommodated in the mounting hole 6, and the end of the adsorption assembly is sealed in the mounting hole 6. When the adsorption assembly is replaced, the new adsorption assembly is directly used to push the adsorption assembly inside the shell 1 for replacement, or the adsorption assembly inside the shell 1 is directly pushed to be disassembled and then replaced.

[0043] In this embodiment, by starting the exhaust fan 19, the exhaust fan 19 is used to exhaust air from the inside of the shell 1, creating a negative pressure effect on the inside of the shell 1, accelerating the flow rate of the exhaust gas inside the shell 1, and diverting the exhaust gas through the support frame and the adsorption assembly, so that the upper and lower adsorption assemblies of the support frame filter the exhaust gas respectively, thereby improving the exhaust gas filtration efficiency. At the same time, the upper or lower part of the support frame is blocked by the baffle, so that the upper or lower adsorption assembly of the support frame can be replaced through the mounting hole 6 without stopping the exhaust gas treatment, making the replacement of the adsorption assembly more convenient and quick. During replacement, due to the suction of the exhaust fan 19, the filtered exhaust gas will be discharged directly and will not stay on the inside of the shell 1.

[0044] Example 2

[0045] like Figure 3-4 As shown, the exhaust gas treatment equipment proposed by the present invention, compared with the first embodiment, in this embodiment, the support frame includes a support plate 11, a partition plate 12 and a guide plate 14;

[0046] There are at least two guide plates 14, which are installed on the inner side of the housing 1 with a gap therebetween. After the adsorption assembly is installed, the gap serves as a movement channel for the exhaust gas after primary filtration to the subsequent filtration process.

[0047] The partition 12 is located between the two guide plates 14 and is installed in the housing 1 to separate the moving channel when in use, so that the exhaust gas is divided into two streams for subsequent filtering processes, so that the exhaust gas has two filtering channels in the housing 1;

[0048] There are two support plates 11 , and the two support plates 11 are located inside the shell 1 and are respectively installed at one end of the partition 12 .

[0049] In an optional embodiment, a limiting strip 13 is provided at the top end of the side of the support plate 11 and the middle part located below the partition 12 and the upper part of the side of the guide plate 14, and a support strip 15 is provided at the bottom end of the side of the support plate 11 and the middle part located above the partition 12 and the lower part of the side of the guide plate 14, wherein the spacing between the limiting strip 13 and the support strip 15 is matched with the height of the adsorption component, and the limiting strip 13 and the support strip 15 are respectively located on the upper and lower end surfaces of the adsorption component, for slidingly connecting with the adsorption component during use, and limiting the position of the adsorption component in the shell 1.

[0050] In this embodiment, the support plate 11 and the partition 12 are arranged in an H shape, and two guide plates 14 are provided above and below the middle of the partition 12, so that when the exhaust gas flows from the air inlet shell 2 through the shell 1 to the air outlet shell 5, it is divided into two streams by the support plate 11, and after being guided by the support plate 11, the partition 12 and the guide plate 14, the two streams of exhaust gas are made to flow in an M and W shape, so that the two streams of exhaust gas pass through at least two adsorption components and move toward the exhaust fan 19.

[0051] Example 3

[0052] like Figure 1-3 As shown, the exhaust gas treatment device proposed by the present invention, compared with the first embodiment, in this embodiment, the baffle includes a motor 3, a baffle bar 7, a baffle body 8, a threaded sleeve 9 and a rotating rod 10;

[0053] The baffle body 8 is slidably mounted on the inner side of the housing 1 and is slidably connected to the support frame;

[0054] There are two baffles 7, which are respectively arranged on the inner walls of the housing 1 and are slidably connected to the baffle body 8;

[0055] The rotating rod 10 is located on the side of the baffle body 8 and is rotatably installed in the housing 1, and the top end extends to the top of the housing 1;

[0056] The threaded sleeve 9 is sleeved on the outer side of the rotating rod 10 and connected to the baffle body 8, wherein the outer side of the rotating rod 10 has a thread, and the threaded sleeve 9 is threadedly connected to the rotating rod 10;

[0057] The motor 3 is mounted on the top of the housing 1 and is transmission-connected to the rotating rod 10 .

[0058] In an optional embodiment, a card slot 17 is provided on the inner side of the shell 1 and above and below the baffle body 8. When the upper and lower parts of the support frame are sealed, the upper and lower ends of the baffle body 8 are fitted and accommodated in the card slot 17, so that the sealing is higher.

[0059] In this embodiment, the motor 3 drives the rotating rod 10 to rotate, and the rotating rod 10 drives the threaded sleeve 9 to move up and down through the thread, and the threaded sleeve 9 drives the baffle body 8 to move toward the slot 17 on the side of the support plate 11, so that the end of the baffle body 8 is inserted into the slot 17 to seal the gap between the support plate 11 and the shell 1. During the movement of the baffle body 8, the baffle bar 7 blocks the edge of the baffle body 8 to improve the sealing effect of the baffle body 8.

[0060] Example 4

[0061] like Figure 5 As shown, the exhaust gas treatment equipment proposed by the present invention, compared with the first embodiment, in this embodiment, the adsorption component includes a placement frame 4 and a filter bag 16;

[0062] The placement frame 4 is slidably mounted on the support frame and has a plurality of ventilation holes 18 at the bottom end;

[0063] The filter bag 16 is placed inside the placement frame 4 and is spread all over the placement frame 4 . The filter bag 16 is made of activated carbon and is used to absorb harmful substances in the exhaust gas.

At the same time, under the action of the exhaust fan 19 and the cooperation of the support frame, the exhaust gas moves toward the filter bag 16 and is discharged through the ventilation hole 18 and moves toward the filter bag 16 through the ventilation hole 18 for multiple adsorption filtration.

[0065] In summary, when the present invention is in use, by starting the exhaust fan 19, the exhaust fan 19 is used to extract air from the inside of the shell 1, and the inside of the shell 1 has a negative pressure effect, so that the exhaust gas inside the shell 1 is accelerated. The exhaust gas is blocked by the support plate 11 and there is a gap between the support plate 11 and the upper and lower ends of the inner side of the shell 1, so that the exhaust gas is divided into two streams inside the shell 1, and after passing through the support plate 11, the partition plate 12 and the guide plate 14, the two exhaust gases are made to flow in an M and W shape. During the flow process, the two exhaust gases move to 16 for adsorption filtration and are discharged through the ventilation hole 18, and then move to the filter bag 16 through the ventilation hole 18 for adsorption filtration, so that the exhaust gas After multiple filtrations, it moves toward the exhaust fan 19. Before the filter bag 16 is saturated with adsorption, the motor 3 drives the rotating rod 10 to rotate. The rotating rod 10 drives the threaded sleeve 9 to move up and down through the thread. The threaded sleeve 9 drives the baffle body 8 to move toward the slot 17 on the side of the support plate 11, so that the end of the baffle body 8 is inserted into the slot 17, and the gap between the support plate 11 and the shell 1 is blocked, so that a stream of exhaust gas is retained on the inside of the shell 1 to flow, and the filter bag 16 for adsorption and filtration of the other stream is replaced through the mounting hole 6. During replacement, due to the suction of the exhaust fan 19, the filtered exhaust gas will be discharged directly and will not stay on the inside of the shell 1.

Various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
