Abstract

The invention relates to the field of chloroethylene synthesis, and discloses an accelerant transfer device. The accelerant transfer device comprises a cover body and a suction device, wherein the cover body is arranged at the top of a chloroethylene converter in a covering way; a suction hole communicated with an inner cavity of the chloroethylene converter is formed in the cover body; the suction device comprises a suction pipe and a suction pump; the suction pipe is inserted into the suction hole and is communicated with a reaction pipe in the chloroethylene converter; accelerants in the reaction pipe are sucked through the suction pump. The accelerant transfer device provided by the invention can realize the accelerant transfer automation; compared with traditional manual operation, the accelerant transfer device has the advantages that the operation is simple; the transfer efficiency is high; the time and the labor are saved; the reaction pipe filled with the accelerants is encapsulated in the converter by the cover body; the opportunity that the human body is in contact with mercury is reduced; the harm of the mercury to the human body is avoided; the green engineering construction is realized.

Description

technical field [0001] The invention relates to the field of vinyl chloride synthesis, in particular to a catalyst transfer device. Background technique [0002] Vinyl chloride monomer is the raw material for the polymerization of polyvinyl chloride. During the production of PVC by the calcium carbide method, the acetylene gas produced by the hydrolysis of calcium carbide and the hydrogen chloride produced by caustic soda react to obtain vinyl chloride monomer. The reaction formula is as follows: [0003] CHCH+HCl→CH 2 CHCl+124.8kJ / mol [0004] The existing synthesis process of vinyl chloride monomer is as follows: acetylene and hydrogen chloride gas are mixed and dehydrated and then enter the front converter. The converter tubes are filled with activated carbon loaded with a low-mercury catalyst to catalyze the synthesis reaction of acetylene and hydrogen chloride to produce vinyl chloride monomer. In this process, the conversion rate of acetylene in the foreground conver...
