Description

Technical Field

[0001] The utility model relates to a continuous stripping device for chlorinated paraffin, belonging to the field of chlorinated paraffin processing. Background Technique

[0002] The crude chlorinated paraffin produced contains partial hydrogen chloride and free chlorine components. After the crude chlorinated paraffin is pumped into the storage cylinder, nitrogen is introduced into the storage cylinder for purging for 1 - 2 hours. After passing the sample analysis, it is transferred out. To make the chlorinated paraffin fully contact with nitrogen, usually the storage cylinder storing chlorinated paraffin is heated to increase the fluidity of the chlorinated paraffin, facilitating the flow of nitrogen through the chlorinated paraffin. Currently, after the nitrogen is discharged from the storage cylinder, it will carry away more heat, resulting in a decrease in the temperature of the chlorinated paraffin. To ensure the fluidity of the chlorinated paraffin, the storage cylinder needs to be continuously heated, thereby increasing the energy consumption and raising the processing cost. Therefore, it is necessary to design a continuous stripping device for chlorinated paraffin that can recover and utilize the discharged heat. Content of the Utility Model
