Problems solved by technology

[0002] In the original boiler flue gas ammonia desulfurization process, the desulfurization efficiency of the desulfurization tower is low, and the desulfurization efficiency is completely increased by the addition of ammonia water, which causes a great waste of resources. The tailing is serious. As the national environmental protection situation becomes increasingly severe, the original ammonia desulfurization process can no longer meet environmental protection requirements and ultra-low emission standards

Abstract

The invention discloses an ammonia desulfurization device, which comprises a flue inlet, a flue outlet, an oxidation section, a concentration section, an absorption section, a recovery section, a washing section, a concentration tank, an ammonia water tank, a washing tank, a first circulating pump, a second Second circulation pump, third circulation pump, fourth circulation pump, oxidation air spray gun. The invention internally divides the original reaction device to form two completely different reaction areas of oxidation and ammonia reduction, which improves the reaction efficiency and ensures the stable operation of the system. The invention also discloses an ammonia desulfurization process. The flue gas enters from the inlet of the flue, and after entering the recovery section, the ammonium sulfate solution with pH<5 generated in the oxidation section is sprayed twice to the flue gas entrained with ammonia. Spray washing, so that part of the ammonium sulfite concentration is always maintained in the absorption circulation liquid, and the ammonia water is changed from the original absorbent to the reducing agent. Improve the utilization efficiency of ammonia water while maintaining the absorption effect of the absorption liquid.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to an ammonia desulfurization device and process. Background technique [0002] In the original boiler flue gas ammonia desulfurization process, the desulfurization efficiency of the desulfurization tower is low, and the desulfurization efficiency is completely increased by the addition of ammonia water, which causes a great waste of resources. The tailing is serious. As the national environmental protection situation becomes increasingly severe, the original ammonia desulfurization process can no longer meet environmental protection requirements and ultra-low emission standards. Contents of the invention [0003] The object of the present invention is to provide an ammonia desulfurization device and process to overcome the above-mentioned deficiencies in the prior art. [0004] The present invention adopts the following technical solutions: an ammonia desulfuriz...
