Desulfurization, denitration, dust removal and white smoke removal integrated intelligent system and desulfurization, dust removal and white smoke removal method thereof

Abstract

The invention discloses a desulfurization, denitration, dust removal and white smoke removal integrated intelligent system and a treatment method adopting the system. The system comprises a tail gas generation system, a desulfurization, dust removal and white smoke removal system communicated with the tail gas generation system through a first gas pipeline, a reactor communicated with the desulfurization, dust removal and white smoke removal system, and a sedimentation tank communicated with the reactor. The bottom of the sedimentation tank is communicated with an oxidation tank through a first slurry pump and a pipeline, the oxidation tank is communicated with the sedimentation tank through a material pipeline main pipe and a first branch pipe, and the oxidation tank is also communicatedwith a filter press through the material pipeline main pipe, a second branch pipe and a second slurry pump. The system and the method can complete desulfurization, denitration and dust removal treatment of polluting gas at the same time, the gypsum rain phenomenon cannot occur in the treatment process, and the white smoke removal effect is achieved. The system is completed through automatic control, the whole system forms a good cycle, the resource utilization rate is increased, and secondary pollution is avoided, therefore the system has good application prospects.

Description

technical field [0001] The invention belongs to the technical field of purification of polluted gas. Specifically, it relates to an integrated intelligent system for desulfurization, denitrification, dust removal and whitening and a method for desulfurization, dust removal and whitening. Background technique [0002] Coal, oil, and natural gas are the three major energy sources in my country and are widely used in industrial production. Due to the high content of elements such as sulfur and nitrogen, such substances will produce polluting gases and particulate matter containing sulfur and nitrogen oxides during use and combustion, and direct discharge will cause serious impact on the environment. Therefore, under the conditions of wide application of coal, oil, natural gas, etc., the desulfurization, denitrification, and dust removal of tail gas have been continuously researched technologies in this industry.

AI Technical Summary

Problems solved by technology

The existing desulfurization and dust removal treatment is complex in operation, consumes a large amount of raw materials, high in cost, and cannot achieve the whitening effect
