Description

Technical Field

[0001] The utility model relates to an activated carbon adsorption box, in particular to a drawer type activated carbon adsorption box. Background Art

[0002] The activated carbon adsorption box is a treatment equipment used to purify large-volume, low-concentration organic waste gas. It mainly uses the adsorption capacity of the surface of the activated carbon adsorbent to make the waste gas contact with the porous activated carbon adsorbent with a large surface. The pollutants in the waste gas are adsorbed on the surface of the activated carbon, which separates it from the gas mixture, and the purified gas is then discharged. The activated carbon adsorption box consists of a box body and an activated carbon adsorption layer filled in the box body. Since the activated carbon will tend to be saturated after adsorbing the pollutants in the gas, the activated carbon needs to be replaced at this time. Therefore, the activated carbon adsorption layer structure mostly adopts a drawer box design, which is convenient for replacing the activated carbon adsorbent.

[0003] The Chinese utility model patent with the authorization announcement number CN214513640U discloses a drawer-type activated carbon adsorption box, which includes a box body and a drawer movably arranged in the box body. By setting a transmission structure between the box body and the drawer, multiple drawers can be pulled out at the same time, which is convenient for replacing the activated carbon adsorbent. However, in the above-mentioned drawer-type activated carbon adsorption box, the drawer is an open structure with poor sealing performance, which is more suitable for larger block activated carbon adsorbents. If a granular activated carbon adsorbent with better adsorption effect is placed in the above-mentioned drawer, the activated carbon adsorbent will spill from the drawer during operation.

Embodiment

[0029] As shown in this embodiment Figures 1 to 4 is a drawer-type activated carbon adsorption box, which includes a box body 1, and a plurality of drawers 4 are detachably and movably placed in the box body 1, and an activated carbon adsorbent 9 is placed in the drawer 4.

[0030] Specifically, as Figure 1 shown, the main body of the box body 1 is a hollow cuboid structure. The box body 1 is made of fiberglass material and has the advantage of corrosion resistance, and can filter corrosive waste gas. The left end of the box body 1 extends outward and is provided with a circular gas inlet 2, and the right end of the box body 1 extends outward and is provided with a circular gas outlet 3. A plurality of drawers 4 are arranged in the box body 1 in a row and column distribution manner. In this embodiment, a total of 48 drawers 4 are arranged in 4 rows and 12 columns in the box body 1. 48 pairs of track angle steels 5 are fixedly arranged in the box body 1. Each pair of track angle steels 5 includes two relatively arranged fiberglass with an "L" cross-section. The drawer 4 can be slidably placed between the two "L"-shaped fiberglass.

[0031] Furthermore, in order to enable the waste gas to be fully filtered through the drawer 4, as Figure 2 shown (the dotted line in the figure represents the outer edge of the drawer), inside the box body 1, three first baffles 6 are fixedly arranged at intervals on the left end surface of the leftmost column of drawers 4. The first baffles 6 are made of fiberglass material. The uppermost first baffle 6 starts from the top of the box body 1 and ends at the same level as the bottom of the first row of drawers 4. The middle first baffle 6 starts from the same level as the top of the second row of drawers 4 and ends at the same level as the bottom of the third row of drawers 4. The lowermost first baffle 6 starts from the same level as the top of the fourth row of drawers 4 and ends at the bottom of the box body 1, so that the gaps between the three first baffles 6 correspond to the gaps between the first row and the second row of drawers 4 and between the third row and the fourth row of drawers 4, that is, after the waste gas enters the box body 1 from the gas inlet 2, it enters the gaps between the second row and the third row of drawers 4 and between the third row and the fourth row of drawers 4. Further, as Figure 3As shown (the dashed line in the figure represents the outer edge of the drawer), on the right end face of the drawers 4 in the rightmost column, two second baffles 7 are fixedly arranged at intervals. The second baffles 7 are made of fiberglass. The two second baffles 7 and the three first baffles 6 are staggered between every two rows of drawers 4. That is, in this embodiment, the upper second baffle 7 starts from being flush with the top of the first row of drawers 4 and ends at being flush with the bottom of the second row of drawers 4. The lower second baffle 7 starts from being flush with the top of the third row of drawers 4 and ends at being flush with the bottom of the fourth row of drawers 4. The two second baffles 7 close the gaps between the second and third rows of drawers 4 and between the third and fourth rows of drawers 4. That is to say, the first baffle 6 and the second baffle 7 are staggered between every two rows of drawers 4, and the longitudinal section of the box body 1 is closed by multiple first baffles 6 and multiple second baffles 7. In this way, when the waste gas enters through the gaps between the second and third rows of drawers 4 and between the third and fourth rows of drawers 4, it will be blocked by the second baffle 7 and cannot be directly discharged from the gas outlet 3. Instead, it can only be discharged from the gas outlet 3 after passing through the corresponding drawers 4 for filtration upward or downward. When the number of rows of the drawers 4 changes, the number of the first baffles 6 and the second baffles 7 is changed correspondingly. As long as it is ensured that the first baffle 6 and the second baffle 7 are staggered between every two rows of drawers 4 and the longitudinal section of the box body 1 is closed by multiple first baffles 6 and multiple second baffles 7, it is okay.

[0032] On the front end face of the box body 1, a hole adapted to the size of the drawer 4 is opened, and a method flange 8 adapted to the drawer 4 is fixedly arranged around the hole. In this embodiment, one method flange 8 is arranged to match the outside of each row of drawers 4. That is, a total of four method flanges 8 are fixedly arranged in this embodiment. As Figure 4 shown, the drawer 4 is a hollow cube structure made of fiberglass, including a top wall 41, a right side wall 42, a bottom wall 43, and a left side wall 44 fixedly connected in sequence. A rear wall is fixedly arranged at the rear ends of the above four walls connected in sequence, and a front wall 45 is detachably arranged at the front end, so that the drawer 4 forms a six-sided closed structure, improving the sealing performance of the drawer 4 and effectively preventing the activated carbon adsorbent 9 from spilling out of the drawer 4. The activated carbon adsorbent 9 in this embodiment is a granular activated carbon adsorbent. It should be noted that since the waste gas in this embodiment passes through the drawer 4 in the height direction, the ventilation holes 46 are arranged on the top wall 41 and the bottom wall 43 of the drawer 4. When the drawer 4 in this embodiment is applied to the box body 1 where the waste gas flows in the left-right direction, the ventilation holes 46 can be correspondingly opened on the left side wall 44 and the right side wall 42 of the drawer 4.

[0033] Furthermore, the length of the top wall 41 in the front-rear direction is less than the lengths of the left side wall 44, the right side wall 42, and the bottom wall 43 in the front-rear direction, so that the front ends of the left side wall 44 and the right side wall 42 protrude relative to the top wall 41. Push-pull holes 47 are opened at the protruding parts of the left side wall 44 and the right side wall 42, which is convenient for the staff to pull out the drawer 4 to take and place the activated carbon adsorbent 9.

[0034] The front wall 45 is detachably arranged at the rear side of the push-pull hole 47. Specifically, on the inner walls of the left side wall 44 and the right side wall 42, limit protrusions 48 are fixedly arranged correspondingly at positions close to the top wall 41. In this embodiment, the limit protrusions 48 are arranged in the height direction, and the vertical distance between the limit protrusions 48 and the top wall 41 is slightly greater than the thickness of the front wall 45, so that the front wall 45 can be slidably arranged at the limit protrusions 48 in the height direction, and a handle 49 for facilitating its sliding is fixedly arranged on the front wall 45. The internal dimension of the box body 1 in the front-back direction is greater than the length of the top wall 41 in the front-back direction and less than the lengths of the left side wall 44 and the right side wall 42 in the front-back direction. After the drawer 4 is placed into the box body 1, the activated carbon adsorbent can be completely located in the box body 1, and at the same time, the push-pull hole 47 can be exposed from the box body 1 to facilitate the pulling out of the drawer 4.

[0035] When using this embodiment, the drawer 4 is pulled out from the box body 1 through the push-pull hole 47, the front wall 45 of the drawer 4 is slid up through the handle 49, the activated carbon adsorbent 9 is placed into the drawer 4, then the front wall 45 is slid down through the handle 49 to make the drawer 4 form a closed structure, and the drawer 4 is placed into the box body 1, and then the waste gas can be introduced from the gas inlet of the box body 1. After using for a period of time, the activated carbon adsorbent 9 in the drawer 4 is replaced.
