Description

Technical Field

[0001] This utility model relates to the field of waste gas purification technology, specifically a waste gas purification device for the preparation of benzoyl chloride. Background Technology

[0002] Benzoyl chloride is an organic compound widely used in dye intermediates, initiators, ultraviolet absorbers, rubber and plastic additives, and pharmaceuticals. It is also used in photography and the production of artificial tannic acid. It was also used as an irritant gas in chemical warfare. Because it has a strong irritant effect on the eyes, skin, mucous membranes, and respiratory tract, the waste gas generated during its production process needs to be purified. Therefore, waste gas purification devices for benzoyl chloride production have been continuously developed and innovated.

[0003] In existing benzoyl chloride preparation waste gas purification devices, the waste gas enters the purification chamber through the gas collection chamber during purification. However, some particulate matter still remains inside the waste gas, which affects the use of air intake and exhaust in the long run. Furthermore, the ventilation pipes will age after long-term use. Therefore, there is an urgent need for a waste gas purification device for benzoyl chloride preparation to solve the above problems. Utility Model Content

The insertion rod 15 moves backward to the inner cavity of the limiting hole 19 inserted into the first fixed plate 17, thereby fixing the filter plate 5 on the air collection box 2.

[0033] In this first embodiment: the purification chamber 1, the filter plate 5 and the gas collection chamber 2 refer to the structure of the purification chamber, filter plate and gas collection chamber in a waste gas purification device for the preparation of benzoyl chloride, which is published in Chinese Invention Patent Publication No. CN214319519U.

[0034] Working Principle: This utility model discloses a waste gas purification device for the preparation of benzoyl chloride. When the gas enters the gas collection box 2, the particulate matter in the waste gas is filtered by the filter plate 5. After a period of use, the filter screen 5 is disassembled. To disassemble the filter plate 5, hold the handle 9, place your thumb on the top of the movable plate 12, and then push the movable plate 12 towards the handle 9. The movable plate 12 moves on the outer edge of the crossbar 11, while the spring 13 is compressed. The movable plate 12 drives the insertion rod 15 to move away from the limiting hole 19 on the first fixed plate 17, and then maintains the position of the movable plate 12. Apply force, grasp handle 9 and rotate handle 9. Handle 9 rotates around pivot 10, and handle 9 drives insertion rod 15 to rotate until it corresponds to the limiting hole 19 on the second fixed plate 18. Then slowly release the force on movable plate 12. Movable plate 12 and insertion rod 15 move backward under the elastic action of spring 13. Insertion rod 15 moves backward to the inner cavity of the limiting hole 19 on the second fixed plate 18, thereby fixing handle 9 to filter plate 5. Then, use handle 9 to pull filter plate 5 out of air collection box 2, so that filter plate 5 leaves the inside of air collection box 2 for cleaning.

[0035] When disassembling the filter screen 5, hold the handle 9 and move the movable plate 12 to move the insertion rod 15 away from the limiting hole 19 on the first fixed plate 17. Then rotate the handle 9 and release the force on the movable plate 12. The movable plate 12 and the insertion rod 15 move backward under the elastic action of the spring 13. The insertion rod 15 moves backward to the inner cavity of the limiting hole 19 on the second fixed plate 18, thereby fixing the handle 9 to the filter screen 5. Then, the filter screen 5 is pulled out from the air collection box 2 through the handle 9, so that the filter screen 5 leaves the inside of the air collection box 2 for cleaning. The operation is simple.

[0036] When installing the filter plate 5, pass the filter plate 5 through the through groove 7 and insert it into the inner cavity of the limiting groove 6. At this time, the sealing gasket 8 is in contact with the inner walls of the limiting groove 6 and the through groove 7 respectively to ensure the sealing performance between the filter plate 5 and the air collection box 2. Then, while holding the handle 9, move the movable plate 12 so that the insertion rod 15 moves away from the limiting hole 19 on the second fixed plate 18. Then rotate the handle 9 and release the force on the movable plate 12. The movable plate 12 and the insertion rod 15 move backward under the elastic action of the spring 13. The insertion rod 15 moves backward to the inner cavity of the limiting hole 19 on the first fixed plate 17, thereby fixing the filter plate 5 on the air collection box 2.
