Abstract

The present invention relates to the technical field of SCR denitrification system, and aims to solve the problem of poor dust collection and cooling effect of the existing SCR system dust collecting ash collection device or the high cost of purchasing a separate cooling device, and provides a cement kiln SCR denitrification system high temperature dust collection ash cooling system and method. Cement kiln SCR denitrification system High-temperature dust collection and ash cooling system includes the original cooling adjustment device of the cement kiln system, air conveying chute and chain conveyor, also includes screw conveyor, bucket elevator, kiln dust buffer bin, Roots blower , an inflatable distribution box and an air conveying chute; the outlet of the cooling adjustment device is connected to the inlet of the bucket elevator through a screw conveyor, and the outlet of the bucket elevator is connected to the kiln ash buffer bin; the outlet of the kiln ash buffer bin Connected to the inflatable distribution box; the two paths of the inflatable distribution box are respectively connected to the air conveying chute and the chain conveyor. The invention has the beneficial effects of good cooling effect, stable material flow and little impact on cement production.

Description

technical field [0001] The invention relates to the technical field of SCR denitrification systems, in particular to a system and a method for cooling dust at high temperature in the SCR denitrification system of a cement kiln. Background technique [0002] The development and application of SCR denitrification technology in cement kilns is an important measure for energy conservation and emission reduction in the cement industry. At present, SCR denitrification systems are relatively seldom used in China, but as the ultra-low emission requirements across the country continue to become stricter, it is imperative to reduce NOx emissions in the cement industry, and the promotion of SCR technology is also the general trend. [0003] In the existing cement plant application cases, for the SCR technology, the cement plant basically chooses a high-dust or medium-dust layout plan, and arranges the SCR system after the C1 outlet and before the waste heat power generation system. ...
