AI Technical Summary

Technical Problem

The existing grate system of waste incinerators is not effective in turning and loosening the waste layer, especially in the horizontal direction, which has little effect on the waste, resulting in low combustion efficiency and problems such as ash leakage, air leakage and blockage.

Method used

It adopts a downward-sloping integrated grate structure, including integrated grate plates, movable grate plates and inclined side beam assemblies. The grate heads are arranged in an alternating manner, combined with a wedge-shaped truncated pyramid structure and an interlaced air duct design, to achieve all-round turning and drying of the waste material layer.

Benefits of technology

It improves the drying and combustion efficiency of waste, reduces slag leakage and blockage, extends the service life of the grate, reduces maintenance costs, and improves the thermal efficiency of the incinerator.

Abstract

The present application relates to the field of grate of solid waste incineration treatment incinerator, disclose the integrated grate of down slope type, including integrated grate piece, integrated movable grate plate and two side inclined edge beam assembly, integrated grate piece, integrated movable grate plate are arranged side by side between two side edge beam assembly, movable support plate is below integrated grate piece, the joint of adjacent movable support plate is connected with movable grate piece, movable grate piece and integrated grate piece are alternately arranged side by side, movable support plate bottom is connected with drive assembly, the grate head on adjacent integrated grate piece, movable grate piece forms staggered arrangement left and right, front and back, and the rear end of grate head is towards the low end of the edge beam assembly.The present application is the integrated grate of down slope type, and the grate head of surface grate is staggered, which produces a comprehensive separation effect on the garbage layer, makes the staggered primary air more easily penetrate the layer, enhances the drying and combustion rate of material, simplifies the parts and system combination structure, greatly reduces the risk of leakage and blockage, effectively shortens the installation and maintenance cycle.
