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.
