AI Technical Summary

Technical Problem

The existing catalyst support grids used in denitrification reactors are inconvenient to replace, and the resistance of gas passing through during use will aggravate the damage to the support grid, causing the catalyst to collapse and fall off, and the long-term and stable operation of the denitrification system cannot be guaranteed.

Method used

A catalyst-supported grille including a grating plate and a mounting frame is designed. Through the coordination of positioning columns, extrusion springs and buffer components, the grating plates are easily installed and replaced, and the resistance during gas circulation is reduced through the reinforcement plates and buffer components, and the service life is extended.

Benefits of technology

It improves the convenience and service life of the catalyst support grille, avoids the damage to the support grille and the problem of catalyst fall off due to gas resistance, and ensures the long-term and stable operation of the denitrification system.
