Title: Fluidized bed type equipment for recovering hydrochloric acid
Inventor: TATEMICHI HIDEO
IPC: C01B7/01
Filed: 1991-01-22
Abstract: PURPOSE:To improve recovering capacity of hydrochloric acid with a small change in an installation by connecting an oxygen feed pipe to a combustion air feed pipe for a reactor and inserting heat exchanges for cooling a circulating liquid in a circulating line in the subject device for recovering hydrochloric acid from concd. hydrochloric acid contg. waste liquid. CONSTITUTION:Hydrochloric acid waste liquid is fed to a venturi scrubber 5 where it is concentrated. While the concentrate is fed to a reactor 1 through a liquid feeder 6, fuel 3 is fed to the reactor 1. At the same time, while oxygen is fed to a combustion air feed pipe from an oxygen feed pipe 17, combustion air is fed to the reactor 1 by a fan 2 to form hydrogen chloride as well as to oxidize iron-component in the waste liquid into iron oxide. The hydrogen chloride thus formed is fed from the reactor 1 to a cyclone 4 for dust collection, and after it is returned to the venturi scrubber 5 for dedusting and cooling, it is fed to an absorber 8 and a brought in contact with a circulating liquid to form hydrochloric acid. The hydrochloric acid formed is collected in the inner bottom part of the absorber 8 and drawn from it at any time to recover the same in a tank 16. At this time, the circulating liquid for the absorber 8 and the scrubber 9 is cooled by heat exchangers 18, 19.
