Industrial flue gas desulfurization and denitrification equipment with effective catalysis for cement production

Abstract

The invention discloses industrial flue gas desulfurization and denitrification equipment with effective catalysis for cement production, which comprises a desulfurization and denitrification mechanism, a flue gas pre-filtering mechanism and a flue gas post-filtering mechanism, whereinthe desulfurization and denitrification mechanism is placed on the ground, and the left side and the right side of the lower end of the desulfurization and denitrification mechanism are fixedly connected with a second ventilation pipe and a third ventilation pipe respectively; the flue gas pre-filtering mechanism is located on the left side of the desulfurization and denitrification mechanism, and the flue gas pre-filtering mechanism and the desulfurization and denitrification mechanism form a communicating structure through a second ventilation pipe; and the flue gas post-filtering mechanism is positioned on the right side of the desulfurization and denitrification mechanism. According to the industrial flue gas desulfurization and denitrification equipment capable of realizing effective catalysis for cement production, flue gas before and after desulfurization and denitrification can be conveniently filtered, filtered matters can be conveniently cleaned, meanwhile, the flue gas can be effectively catalyzed, the desulfurization and denitrification effect is good, the flue gas after desulfurization and denitrification can be conveniently adsorbed and purified, and the influence of discharged flue gas on the environment is reduced.

Description

technical field [0001] The invention relates to the technical field of cement production, in particular to an effectively catalyzed industrial flue gas desulfurization and denitrification equipment for cement production. Background technique [0002] In the process of cement production, it needs to go through crushing and pre-homogenization, homogenization of raw meal preparation, preheating decomposition, firing of cement clinker, cement grinding and packaging, etc., in order to reduce environmental pollution and human health The flue gas generated in the cement production process is often desulfurized and denitrified by industrial flue gas desulfurization and denitrification equipment. [0003] For example, the Chinese utility model patent with the authorized announcement number CN108636080B discloses a kind of industrial flue gas desulfurization and denitrification equipment, including ammonia gas input pipe, blower, dust removal mechanism, screw conveyor, conveying mecha...

AI Technical Summary

Problems solved by technology

[0009] The purpose of the present invention is to provide a kind of industrial flue gas desulfurization and denitrification equipment for effectively catalyzing cement production, to solve the above-mentioned background technology, such as the Chinese utility model patent whose authorization announcement number is CN108636080B discloses a kind of industrial flue gas desulfurization and denitrification equipment, In the actual use process, it is generally not convenient to filter the flue gas before and after desulfurization and denitrification, it is not convenient to clean the filtered matter, and it is difficult to make the flue gas fully contact with the catalytic powder, so that it is difficult to effectively catalyze the flue gas, desulfurization and denitrification The effect is limited, and it is not convenient to adsorb and purify the flue gas after desulfurization and denitrification, it is easy to cause a great impact on the environment, and it is difficult to protect the environment
