Problems solved by technology
[0003] The acid mist will directly volatilize into the atmosphere, causing environmental pollution; at the same time, as an important chemical raw material, the volatilization of acid mist also causes great waste
[0004] In the prior art, aluminum hydroxide, calcium chlorate powder, and hydrochloric acid react to form polyaluminum chloride, which will generate acid mist containing zinc chloride during the reaction in the integrated tank, and direct discharge will cause air pollution
[0005] If the reaction tank of the prior art needs to carry out waste gas treatment, additional purification equipment needs to be installed, the production cost is high, and the floor area is large, which needs to be improved

The invention discloses a reaction device for producing polyaluminum chloride. The reaction device comprises a reaction tank, wherein the reaction tank is divided by a middle partition into an upper chamber and a lower chamber; an inner center cylinder and an outer center cylinder are arranged in the lower chamber; a feed pipe is arranged at the bottom end of the lower chamber; a necking is arranged at the tail end of the feed pipe and stretches to the bottom end of the inner center cylinder; a slurry outlet is formed close to the top end of the lower chamber; an exhaust pipe is arranged at the center of the middle partition and stretches into the upper chamber; an absorption filler is arranged in the upper chamber; a spray device is arranged above the absorption filler and comprises a main pipe stretching in from the top end of the upper chamber and a branch pipe connected with the main pipe; a spray hole is formed in the branch pipe; a spray head is arranged on the spray hole; an exhaust pipe is arranged on the side wall close to the top end of the upper chamber and connected with an exhaust fan through a pipeline; and the exhaust fan is connected with an exhaust chimney. With a small floor area and a simple structure, the reaction device can purify the generated waste gas during reaction.
Description
technical field [0001] The invention relates to equipment for producing an inorganic polymer coagulant, in particular to a reaction device for polyaluminum chloride. Background technique [0002] Concentrated acids such as hydrochloric acid are easy to volatilize to form acid mist. If the sealing device of the storage device storing concentrated hydrochloric acid is damaged, concentrated salt [0003] The acid mist will directly volatilize into the atmosphere, causing environmental pollution; at the same time, as an important chemical raw material, the volatilization of acid mist also causes great waste. [0004] In the prior art, aluminum hydroxide, calcium chlorate powder, and hydrochloric acid react to produce polyaluminum chloride, which will generate acid mist containing zinc chloride during the reaction in the integrated tank, and direct discharge will cause air pollution. [0005] If the reaction tank of the prior art needs to carry out waste gas treatment, additiona...
