Combined type combined denitration equipment for sintering flue gas treatment and implementation method of combined type combined denitration equipment

Abstract

The invention discloses composite combined denitration equipment for sintering flue gas treatment and an implementation method of the composite combined denitration equipment, and belongs to the technical field of sintering flue gas treatment.The composite combined denitration equipment comprises a denitration reaction tank, a flue gas inlet is formed in the bottom end of the denitration reaction tank and connected with a flue gas conveying pipe, and a denitration assembly is arranged in the denitration reaction tank. According to the combined type combined denitration equipment for sintering flue gas treatment and the implementation method of the combined type combined denitration equipment, internal particle impurities are effectively removed, the flue gas purity is improved, the spraying positions of the spraying pipes are adjusted, the multiple sets of spraying pipes are arranged in a surrounding and dispersing mode with the connecting pipeline as the center, the spraying uniformity is effectively improved, it is guaranteed that flue gas makes contact with a reducing agent, and the reduction efficiency is improved; and the scraping bristles clean the spraying surface of the atomizing nozzle, and through internal and external cleaning, the spraying quality of the atomizing nozzle is effectively guaranteed, spraying holes are prevented from being blocked, the atomizing quality is improved, internal water vapor is effectively collected, water resource utilization is improved, repeated utilization can be achieved, and energy waste is reduced.

Description

technical field [0001] The invention relates to the technical field of sintering flue gas treatment, in particular to a compound combined denitration equipment for sintering flue gas treatment and an implementation method thereof. Background technique [0002] Desulfurization and denitrification is one of the important technical measures to prevent and control air pollution. In order to prevent excessive NOx pollution from the combustion of coal in the boiler, denitration treatment of coal should be carried out. It is divided into pre-combustion denitration, combustion process denitration, and post-combustion denitration. According to the formation mechanism of nitrogen oxides in cement kilns, there are two types of technical measures for reducing nitrogen and emission reduction in cement kilns: one is to control them from the source. The other type is governance from the end. [0003] The existing denitration equipment sprays the treatment agent at a fixed angle, resultin...

AI Technical Summary

Problems solved by technology

[0003] The existing denitrification equipment sprays the treatment agent at a fixed angle, resulting in a small spraying range and uneven spraying, resulting in poor treatment efficiency;

[0004] Secondly, when the existing denitrification equipment is in contact with the flue gas for a long time, it is easy to block the nozzle hole, resulting in the inability to spray the atomized reactant, which affects the treatment structure
