Abstract

The invention belongs to the technical field of ammonia process smoke gas desulfurization, and particularly relates to a function guidance product partition ammonia process desulfurization oxidation circulation tank device and method. The device comprises a desulfurization tower absorption section and an oxidation circulation tank, wherein the desulfurization tower absorption section and the oxidation circulation tank are connected through a pipeline; the oxidation circulation tank is separated into three regions including a single phase liquid region, an oxidation region and a reduction region by tank wall plates and separation plates; one side of the reduction region is communicated with the oxidation region; the other side of the reduction region is communicated with a desulfurization circulation pump through a pipeline; the oxidation region is communicated with the single phase liquid region; the single phase liquid region is communicated with an ammonium sulfate material transferpump through a pipeline; an oxidation aeration layer is arranged inside the oxidation region, and is communicated with an oxidation fan through a pipeline. The absorbing capacity of absorption slurryon SO2 is greatly improved; the smoke gas desulfurization effect is enhanced; the field operation environment is greatly improved; the continuous and stable discharging of ammonium sulfate by-productsis ensured.

Description

technical field [0001] The invention belongs to the technical field of ammonia-based flue gas desulfurization, and in particular relates to an ammonia-based desulfurization oxidation circulation tank device and method for function-oriented product partitioning. Background technique [0002] In recent years, the air pollution caused by flue gas emissions from coal-fired industrial boilers has attracted more and more attention from the public. SO 2 It is one of the most important pollutants in coal combustion flue gas. At present, the mainstream desulfurization methods include dry method, semi-dry method and wet method. Among them, wet ammonia desulfurization has the advantages of good desulfurization effect, no "three wastes" generation, and resource recovery of desulfurization by-products. It is widely used in chemical industry, coal chemical industry and other industries. The coal-fired industrial boiler has a wide range of applications. [0003] In the conventional ammo...
