Description

Reaction tank for producing calcium chloride solution through hydrochloric acid reaction without stopping production of clean tank Technical Field The utility model relates to the technical field of reaction tanks, in particular to a reaction tank for producing a calcium chloride solution by hydrochloric acid reaction without stopping production of a clean tank. Background In the modern chemical industry, there are a number of industries that produce hydrochloric acid as a byproduct. The byproduct hydrochloric acid has low price, difficult sales and strict transportation pipe, and anhydrous calcium chloride particles with high added value (regenerated after the reaction to generate the calcium chloride solution) are reasonably selected in the factory. As the limestone used in the reaction contains impurities (mainly quartz sand which is internally tubercular and does not react with hydrochloric acid, and is hereinafter referred to as tuberculosis) and waste residues are formed, the part of the limestone generally accounts for 10-15% of the weight of the quartz stone, the existing reaction tank must be stopped to discharge reaction residual acid after a period of operation, and the tank is manually cleaned to clean the residual quartz sand, otherwise, the volume of the tank body is occupied by the quartz sand, and the using effect is affected. Disclosure of utility model The utility model aims to provide a reaction tank for producing a calcium chloride solution by hydrochloric acid reaction without stopping production of a clean tank, so as to solve the problems in the prior art. In order to solve the technical problems, the utility model provides the technical scheme that the reaction tank for producing the calcium chloride solution through the hydrochloric acid reaction without stopping production of the cleaning tank comprises a tank body, wherein a filter residue grating is fixedly connected to the inner wall of the tank body, coarse residue washing legs are arranged at the bottoms of the filter residue grating, slag discharging valves are fixedly connected to outlets of the coarse residue washing legs, a slag storage hopper is connected to an output end of the slag discharging valves in a conducting manner, and a slag discharging valve is fixedly connected to an output end of the slag storage hopper.
