Continuous stripping process and device for chlorinated paraffin

Abstract

The invention discloses a continuous stripping process for chlorinated paraffin, which comprises the following steps: transferring coarse chlorinated paraffin into a chlorinated paraffin buffer tank and delivering the coarse chlorinated paraffin to a chlorinated paraffin stripping tower to perform stripping by the nitrogen; delivering the chlorinated paraffin to a chlorinated paraffin intermediate tank, adding a stabilizer to perform mixing treatment, and delivering the treated chlorinated paraffin to a finished product intermediate tank; after the stripping, delivering the nitrogen to an acidic filter tower and an alkaline tower to allow the nitrogen to be absorbed; and delivering the nitrogen to a nitrogen drying tower to dry the nitrogen. The invention also discloses a continuous stripping device for chlorinated paraffin, which comprises the chlorinated paraffin buffer tank, a chlorinated paraffin intermediate pump, a chlorinated paraffin stripping tower, a chlorinated paraffin stripping pump, the chlorinated paraffin intermediate tank, the acidic filer tower, the alkaline filter tower, an alkaline vapor capturer, a nitrogen gas cabinet, a nitrogen compressor, a water vapor capturer, the nitrogen drying tower and the like. The process and method can perform continuous modification for refining the chlorinated paraffin product, improve the automation of production, realize the recycling of the nitrogen and improve the utilization rate of energy.

Description

technical field [0001] The invention relates to a continuous stripping process of chlorinated paraffin and a device thereof. Background technique [0002] At present, most of the existing chlorinated paraffin devices in my country are continuously chlorinated, and the crude chlorinated paraffin produced contains part of hydrogen chloride and free chlorine. After refining the kettle, blow off the bottom of the kettle with nitrogen for 1-2 hours, and transfer out after the sample analysis is qualified. It has the following disadvantages: it is intermittent production, the number of sets of equipment is large, the labor intensity is high, the degree of automation is low, and the amount of nitrogen is large, resulting in waste of energy. It can be seen from this that product refinement is the bottleneck that restricts the realization of complete continuous production and the expansion of production scale, and a solution is urgently needed.
