AI Technical Summary

Technical Problem

In SCR denitrification units, the pores of the catalyst are easily clogged by dust, resulting in decreased catalytic efficiency and difficulty in cleaning. Existing dust removal efficiency is low.

Method used

A catalyst dust removal and anti-wear device was designed, which includes an ultrasonic cleaning tank and a motor-driven catalyst. The catalyst height is adjusted by the motor, and it is cleaned regularly. The catalyst is fixed by a support block and a buffer spring to prevent displacement and damage. Limiting slide bars and buffer springs are set to buffer stress, thereby improving cleaning efficiency and device stability.

Benefits of technology

It effectively prevents catalyst pore blockage, extends catalyst life, improves cleaning efficiency, reduces production costs, and enhances equipment stability and sealing performance.
