Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, and more specifically to a VOCs waste gas treatment device for oil refining. Background Technology

[0002] VOCs waste gas from oil refining refers to the volatile organic compound waste gas generated in the petrochemical industry during refining, cracking, and synthesis processes. These waste gases mainly include aromatic compounds such as benzene, toluene, and xylene, as well as olefin compounds such as ethylene, propylene, and butadiene, which can pollute the atmospheric environment. Before being emitted, these waste gases need to undergo systematic purification treatment. Currently, activated carbon adsorption boxes are a common component in VOCs waste gas treatment systems, which filter the organic components in the waste gas through the adsorption effect of activated carbon.

[0003] Currently, most common activated carbon adsorption boxes consist of a box body with two open ends and several drawers for placing activated carbon. Placing or replacing activated carbon requires unlocking and pulling out the drawers. The existing activated carbon adsorption boxes mostly lock the drawers to the box body using several bolts. The bolts pass through the outer panel of the drawer and are screwed into the outer shell of the box. When pulling out the drawer, the staff needs to remove all the bolts one by one. Some large activated carbon adsorption boxes have a large number of drawers. When placing or replacing activated carbon, the staff needs to repeatedly disassemble and reassemble a large number of bolts, which is time-consuming, labor-intensive, and slow. Therefore, there is an urgent need to design a VOCs waste gas treatment device for oil refining to solve the above problems. Utility Model Content

[0017] A VOCs waste gas treatment device for oil refining includes an activated carbon adsorption box body 1, and also includes several drawer assemblies 2, several locking assemblies 3, and several L-shaped rods 6. The drawer assemblies 2 are all slidably installed inside the activated carbon adsorption box body 1, the locking assemblies 3 are disposed inside the drawer assemblies 2, and the several L-shaped rods 6 are all fixedly installed inside the activated carbon adsorption box body 1. The drawer assembly 2 is slidably installed between two L-shaped rods 6. The drawer assembly 2 includes a square plate 201 and a storage drawer 202. The storage drawer 202 is slidably installed between two L-shaped rods 6. The square plate 201 is fixedly installed on one side of the storage drawer 202. The locking assembly 3 includes a rotating column 301, a handle 302, and a round plate 303. The rotating column 301 rotates inside the square plate 201. The handle 302 is fixedly installed on one side of the rotating column 301. The round plate 303 is fixedly installed on the other side of the rotating column 301.

[0018] Specifically, a circular hole 203 is provided between the two sides of the square plate 201, and the rotating column 301 is rotatably installed in the circular hole 203.

[0019] Specifically, the activated carbon adsorption box body 1 has several placement openings 4 on one side. The storage drawer 202 is adapted to the placement openings 4. The locking assembly 3 also includes two connecting rods 304, two sliding rods 305, and two insert rods 306. One end of the two connecting rods 304 is symmetrically and rotatably mounted on one side of the circular plate 303. The two sliding rods 305 are rotatably mounted on the other end of the two connecting rods 304, and both sliding rods 305 are slidably mounted on the inner side of the square plate 201. The two insert rods 306 are respectively fixedly mounted on one end of the two sliding rods 305, and the two insert rods 306 are respectively slidably inserted into the inner walls of both ends of the placement openings 4.

[0020] Specifically, two insertion holes 5 are provided on the inner walls at both ends of the placement port 4, and the insertion holes 5 are adapted to the insertion rod 306.

[0021] Specifically, the locking assembly 3 also includes two sliders 307 and two springs 308. The two sliders 307 are respectively fixedly installed on the side where the two slide rods 305 are attached to the square plate 201. Two strip grooves 206 are symmetrically opened on the inner side of the square plate 201. The two sliders 307 are respectively slidably installed in the two strip grooves 206. One end of the two springs 308 is respectively fixedly installed on one end of the two sliders 307, and the other end of the two springs 308 is respectively fixedly installed on the inner wall of one end of the two strip grooves 206.

[0022] Specifically, the drawer assembly 2 also includes several ball bearings 205, which are symmetrically distributed at equal intervals on the bottom of the storage drawer 202. The inner wall of the L-shaped rod 6 is provided with arc-shaped grooves 7, which are adapted to the ball bearings 205. Ventilation holes are evenly provided on the storage drawer 202.

[0023] In this embodiment, the ball bearings 205 and the arc groove 7 can reduce the friction between the storage drawer 202 and the L-shaped rod 6 when sliding, making it easier for staff to pull out or push back the storage drawer 202.

[0024] Specifically, drawer assembly 2 also includes a partition 204, which is fixedly installed inside the storage drawer 202.

[0026] Working principle: When it is necessary to place or replace activated carbon, first hold the handle 302, then rotate the handle 302, which drives the rotating column 301 to rotate. The rotation of the rotating column 301 will drive the circular plate 303 to rotate. The rotation of the circular plate 303 will pull the two connecting rods 304 to slide and rotate. When the two connecting rods 304 slide, they will pull the two sliding rods 305 closer together. The two sliding rods 305 will cause the two insert rods 306 to disengage from the insertion hole 5. When the insert rods 306 are completely disengaged from the insertion hole 5, the square plate 201 and the storage drawer 202 can be unlocked. At this time, pull the handle 302 outward to pull out the square plate 201 and the storage drawer 202. The drawer 202, with its two sliding rods 305 moving closer together, will also cause the two sliders 307 to slide within the slot 206 and compress the two springs 308. After the activated carbon is placed or replaced, rotate the handle 302 again and push the handle 302 to reset the square plate 201 and the drawer 202. Then release the handle 302, and the two springs 308 will be released and push the two sliders 307 to reset. The reset of the two sliders 307 will cause the two sliding rods 305 to reset. The reset of the two sliding rods 305 will cause the two insert rods 306 to re-engage into the insert hole 5, thereby re-locking the square plate 201 and the drawer 202.

[0027] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
