Electrolytic magnesium anode sublimate filtering device

Abstract

The invention relates to an electrolytic magnesium anode sublimate filtering device which is characterized in that a chlorine concentration detector is arranged on an elliptical seal head at the top of a cylinder body, a chlorine outlet assembly, a differential pressure transmitter and a pulse dust-cleaning device are arranged at the upper part of the cylinder body, an accident state treatment valve and a nitrogen replacement device are arranged at the middle of the cylinder body, an assistance type access door is arranged the lower part of the cylinder body, a conical ash hopper is arranged at the bottom of the cylinder body, a tangent air inlet assembly is arranged on the conical ash hopper, a filter unit is arranged in the cylinder body, an airflow distributing device is arranged on the tangent air inlet assembly, and an ash hoper air hammer, an ash hopper manual gate valve, a metal compensator and a shaft-free spiral ash conveyor are sequentially arranged at the bottom of the conical ash hopper. The electrolytic magnesium anode sublimate filtering device is capable of filtering and purifying an electrolytic magnesium anode sublimate to ensure that purified high-concentration chlorine can be used as a production raw material of PVC (polyvinyl chloride), and has the characteristics of simplicity in control, high filtering and purifying efficiency, good sealing property, safety and reliability in operation, tangent air inlet, and thorough ash removal.

Description

Technical field [0001] The invention belongs to the technical field of environmental protection, and relates to a filtering device for purifying electrolytic anode sublimate collected by a chlorine gas conduit of an electrolytic magnesium device, and in particular to a filtering device for electrolytic magnesium anode sublimate. Background technique [0002] At present, the production process of using electrolytic magnesium chloride to obtain metallic magnesium and chlorine gas has been successful at home and abroad. The anode sublimate produced in the electrolytic magnesium production process has the characteristics of high concentration of chlorine gas, high corrosiveness, high toxicity, high temperature, fine particles and so on. Traditional filter equipment has weak corrosion resistance, dust removal and adhesion, complex equipment switching, and system airtightness cannot guarantee the safety of the environment, nor can it meet the needs of the production process.
