Abstract
Description
Technical Field
[0001] This utility model relates to the field of chlorinated paraffin production technology, and more specifically to a protective device for chlorinated paraffin production. Background Technology
[0002] During the production of chlorinated paraffin, chlorine gas needs to be introduced into the paraffin to react. As a result, chlorinated paraffin will contain some hydrogen chloride vapor and unreacted chlorine gas during the production process. These gases can be harmful to the human body. After the relative density and chlorine content of chlorinated paraffin reach the standard, the impurities in the chlorinated paraffin need to be removed to ensure the safety of the chlorinated paraffin. The impurity removal process usually involves passing the chlorinated paraffin into a degassing tower for long-term degassing treatment.
[0003] Because chlorinated paraffin has a high viscosity, some of it will adhere to the inner wall of the degassing tower. The adhered chlorinated paraffin is difficult to remove, which means that the inside of the degassing tower needs to be cleaned regularly, increasing the labor intensity of the staff.

The L-shaped stirring rod 49 agitates the chlorinated paraffin, causing the chlorine and hydrogen chloride gases inside the chlorinated paraffin to flow out. The suction fan 31 draws the chlorine and hydrogen chloride gases out of the reactor body 1 through the suction branch pipe 32. The chlorine and hydrogen chloride gases are then transported through the suction branch pipe 32 to the exhaust branch pipe 33, and then through the exhaust branch pipe 33 to the sodium hydroxide solution inside the degassing tank 34. The sodium hydroxide solution absorbs the chlorine and hydrogen chloride gases, thereby preventing the waste gas from polluting the environment.

Tap water is then introduced through the second water pipe 42, which is then transported to the first water pipe 41. The first water pipe 41 is then transported to two connecting pipes 43, and then to the annular pipe 44. The water is then sprayed out through multiple nozzles at the bottom of the annular pipe 44 to clean the inner wall of the vessel 1. The first water pipe 41 drives the two connecting pipes 43 and the annular pipe 44 to rotate, which in turn causes the annular pipe 44 to rotate and spray water, thus quickly and evenly cleaning the inner wall of the vessel 1. Two electric push rods 45 drive two support plates 451 to move downwards, and the two support plates 451 drive the annular scraper 452 to move downwards, which scrapes off the chlorinated paraffin adhering to the inner wall of the vessel 1.
