[0030] The following combines the drawings in the embodiments of the present utility model to clearly and completely describe the technical solutions in the embodiments of the present utility model. Many specific details are set forth in the following description in order to fully understand the present utility model, but the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0031] As Figures 1 to 5 shown, a tail gas adsorber with a temperature monitoring function provided by the embodiment includes a box body 1 in the shape of a cuboid. An air inlet 11 and an air outlet 12 are respectively arranged at both ends of the box body 1 in the length direction. A drawer 2 with a hollow bottom is arranged in the box body 1 for containing adsorbent fillers, such as activated carbon;

[0032] There are multiple drawers 2, and the multiple drawers 2 are arranged in two rows up and down. The multiple drawers 2 in the same row are arranged along the length direction of the box body 1;

[0033] The drawer 2 can be pulled out along the width direction of the box body 1. Specifically, a plurality of support rods 9 are arranged in the box body 1 along the width direction. The multiple drawers 2 are placed on the multiple support rods 9. At the same time, a plurality of openings (not marked) for pulling out the drawer 2 are provided on the side wall of the box body 2. A U-shaped handle 21 is arranged on the outer side surface of the drawer 2;

[0034] A vertically penetrating strip-shaped hole 211 is arranged in the middle of the upper part of the handle 21 of the drawer 2 in the lower row, and magnetic blocks 212 are arranged in the middle of the horizontal section of the handle 21 of the drawer 2 in the lower row;

[0035] A vertical scraper 3 is provided at the bottom of the inner side of the box body 1. The scraper 3 is a strip-shaped plate. The scraper 3 extends along the length direction of the box body 1. A plurality of connecting rods 31 are fixed to the scraper 3. The connecting rods 31 pass through the side wall of the box body 1 having an opening.

[0036] The plurality of connecting rods 31 correspond to the plurality of drawers 2 in the lower row one by one, and the protruding ends of the plurality of connecting rods 31 are all pivotally connected to the rotating rods 32, and the rotating paths of the free ends of the plurality of rotating rods 32 pass through the bar-shaped holes 211 on the corresponding handles 21;

[0037] The rotating rod 32 is perpendicular to the connecting rod 31 and is located directly below the corresponding strip hole 211. Specifically, an annular groove (not shown) is provided at the protruding end of the connecting rod 31, and a circular hole (not shown) is provided at the pivot end of the rotating rod 32. The inner wall of the circular hole is embedded in the annular groove to complete the pivot connection. Alternatively, in another embodiment, a bearing is provided, the inner ring of the bearing is fixedly connected to the protruding end of the connecting rod 31, and the outer ring of the bearing is fixedly connected to the inner wall of the circular hole.

[0038] Two vertical first baffles 4 and one vertical second baffle 5 are arranged in the box body 1;

[0039] The first baffle plate 4 is located on a side of the drawer 2 close to the air outlet 12, and the second baffle plate 5 is located on a side of the drawer 2 close to the air inlet 11;

[0040] The heights of the two first baffles 4 correspond to the heights of the upper and lower rows of drawers 2, respectively. There is a gap between the two first baffles 4. The height of the second baffle 5 is located between the upper and lower rows of drawers 2. The top of the second baffle 5 is not lower than the bottom of the upper row of drawers 2, and the bottom is not higher than the top of the lower row of drawers 2.

[0041] In this embodiment, the multiple drawers 2 are all located between the first baffle plate 4 and the second baffle plate 5. The multiple drawers 2 are regarded as a whole, and the first baffle plate 4 and the second baffle plate 5 are attached to two ends of the whole.

[0042] The width of the first baffle plate 4 and the second baffle plate 5 is the same as the width of the inner space of the box body 1 .

[0043] Furthermore, a vertically penetrating ash discharge port 14 is provided on the bottom wall of the box body 1 along the length direction, and an ash hopper 8 capable of covering the ash discharge port 14 is detachably provided on the bottom surface of the box body 1. Specifically, slide rails 15 with an L-shaped cross section are provided on both sides of the ash discharge port 14 on the bottom surface of the box body 1, and the ash hopper 8 cooperates with the slide rails 15 and can move along the slide rails 15;

[0044] Furthermore, a nitrogen interface 7 and a temperature sensor interface 6 are provided on the side wall of the box body 1 , and a plurality of spray pipes 13 are provided on the top of the inner side of the box body 1 .

[0045] The working principle of this application is as follows: Organic waste gas, such as waste gas containing acetone, is input through the air inlet 11. After being blocked by the second baffle 5, the waste gas first moves to the top and bottom inside the box body 1, and then enters between the upper and lower rows of drawers 2 after being adsorbed by the activated carbon in the multiple drawers 2. Then it passes between the two first baffles 4 and is discharged from the air outlet 12.

[0046] When it is necessary to replace the activated carbon, the drawer 2 can be pulled out by the handle 211. Before pulling out the lower row of drawers 2, the free end of the rotating rod 32 is rotated into the strip hole 211 and magnetically attracted to the magnet 212. Then the handle 211 is pulled, and the vertical plate 3 is pulled outwards by the connecting rod 31. The vertical plate 3 scrapes the impurities deposited at the bottom inside the box body 1 and drives them to the ash discharge port 14. The impurities fall from the ash discharge port 14 into the ash hopper 8, and then the drawer 2 can be refilled and pushed back into the box body 1.

[0047] Since it is not necessary to remove the impurities at the bottom inside the box body 1 every time the drawer 2 is pulled out, at this time, the free end of the rotating rod 32 can be rotated out of the strip hole 211, and only the lower row of drawers 2 can be pulled out.

[0048] When the ash hopper 8 needs to be cleaned, the ash hopper 8 can be pulled out for cleaning.

[0049] During the tail gas adsorption treatment process, the internal temperature of the box body 1 is monitored by the temperature probe in the temperature probe interface 6. If the temperature exceeds the threshold value, the supply of tail gas into the box body 1 is stopped, and the air pump is started to introduce the nitrogen in the nitrogen tank into the box body 1 through the nitrogen interface 7. At the same time, the water pump is started to spray water into the box body 1 through the spray pipe 13 to prevent the organic components and activated carbon inside the box body 1 from burning or exploding due to excessive temperature.

[0050] The temperature probe can be selected from the types with a built-in display screen, such as the BD-TC-FB series of Shenzhen Botian Technology Co., Ltd.

[0051] Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
