Abstract

The invention provides an ultraclean emission type ammonia-process desulfurization device and technology. The device provided by the invention comprises a pre-washing tower, an absorption tower and anadsorption tower, which are connected in sequence, wherein a flue gas inlet is arranged at the top of the pre-washing tower; a side wall of the pre-washing tower is connected with a side wall of theabsorption tower through a flue gas channel; the top of the absorption tower is connected with the top of the adsorption tower through a flue gas pipeline; a flue gas outlet is arranged on the side wall of the adsorption tower; an activated carbon adsorption layer is arranged on the adsorption tower along a flue gas movement direction. The device provided by the invention is used for treating fluegas; multi-spraying, demisting and dust removal measurement are used and activated carbon adsorption treatment is finally increased, so that the desulfurization and dust removal efficiency is effectively improved; especially, the activated carbon adsorption layer can be used for effectively treating blue smoke or yellow smoke aerosol formed in a smoke pipe outlet and ultraclean emission of dust concentration of the smoke pipe outlet of the desulfurization device can be met.

Description

technical field [0001] The invention belongs to the field of flue gas purification, and in particular relates to an ultra-clean ammonia discharge desulfurization device and a process. Background technique [0002] Ammonia desulfurization, as a high-efficiency wet desulfurization process, has taken a firm place in my country's popularization and application. The ammonia method is a recovery method, which can make full use of my country's extensive ammonia sources to produce sulfur fertilizers and make up for the gap in my country's large imports of sulfur. It not only controls the pollution of sulfur dioxide, but also meets the long-term and large demand for fertilizers. Continuous research and development and promotion have been carried out in China. And successively launched a new ammonia desulfurization process. However, during the actual operation of the ammonia-based flue gas desulfurization process, the existing desulfurization device achieves desulfurization by adding ...
