Intelligent denitration method and intelligent denitration device for spray drying tower

Abstract

The invention discloses an intelligent denitration method and an intelligent denitration device for a spray drying tower. The device comprises a control system, a CEMS (continuous emission monitoring system) online monitoring module, a reducing agent conveying module, a reducing agent preparation module and a spray gun; the intelligent denitration method monitors the content of nitric oxide in the drying tower in real time through a CEMS, controls the system to control the whole denitration process, uses the intelligent spray gun to accurately control the use amount of a reducing agent, and prevents the excessive reducing agent from overflowing to corrode equipment, affect the product quality and pollute the environment; the method in the scheme can control the denitration operations of a plurality of spray drying towers at the same time through one control system, control in a combined manner, improve the working efficiency, reduce the launching of the equipment, and save the cost.

Description

technical field [0001] The invention relates to the technical field of denitrification, in particular to an intelligent denitrification method and device for a spray drying tower. Background technique [0002] The "Ceramic Industry Pollutant Discharge Standard" (GB 25464-2010) of the ceramic industry stipulates strict requirements on the nitrogen oxide emission indicators of spray towers and firing kilns. Equipped with a simple SNCR denitrification device, the device relies heavily on manual operation, the preparation concentration of the reducing agent is unstable, the consumption of the reducing agent is large, and the excess reducing agent escapes a large amount, which seriously corrodes the equipment and seriously affects the quality of the product. and pollute the environment; the denitrification method is simple, the injection amount of the reducing agent cannot be adjusted, and each spray tower needs to be equipped with a separate denitrification device, which cannot ...

AI Technical Summary

Problems solved by technology

[0004] In view of the shortcomings of the above-mentioned prior art, the purpose of the present invention is to provide a method and device for intelligent denitrification of a spray drying tower, aiming to solve the problem that the denitrification method in the prior art is simple and extensive, and cannot accurately control the amount of reducing agent used , causing excess reducing agent to be released into the environment, which not only corrodes equipment, affects product quality, but also causes serious pollution to the environment
