Sectional drive combined type fire grate system

Abstract

The invention relates to a compound expression fire grate system with subsection drive, which characteristic lies in: the incinerator has divided into the dry section (1), hot region (2), burn cinders section (3) in turn from high to low, the height fall has existed between each section; underneath the dry section, the hot region and the burn cinders section separately establishes the unaided once-wind chamber (9, 11, 13) and the respective driving mechanism (8, 10, 12); the fire grate piece of the dry section (1) and the burn cinders section (3) is the push type arrangement, the fire grate piece of the hot region (2) is the counter push type arrangement. The invention divides the fire grate into the dry section fire grate, the hot region fire grate, the burn cinders section fire grate three parts; each section not only has the unaided driving system, the wind system and the wind chamber, and is advantageous for the independent control; moreover the height fall exists between each section, is advantageous for the further scatter, turn over and agitation when the trash falls.

Description

technical field [0001] The invention relates to an incinerator fire grate system which is a key component for solid waste incineration treatment. Especially the composite grate system of the incinerator involving municipal solid waste. Background technique [0002] The most important component of a waste incinerator is the incinerator grate system. The incinerator grate system is responsible for the transportation of garbage in the furnace, and at the same time improves the mixing and disturbance of garbage and air to improve combustion efficiency. [0003] Various types of incineration grate systems are available, in particular so-called reciprocating incineration grate systems. The grate pieces in the form of a reciprocating grate are regularly overlapped like roof tiles to form a support for garbage burning. The movable grate pieces that can move back and forth alternately with the fixed grate pieces, and their relative motion causes the garbage to move forward and bac...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a segmented drive composite fire grate system to solve the problem of insufficient drying, incomplete agitation and dispersal caused by the small height difference and the consistent motion direction of the grate pieces during the incineration process of urban waste with high moisture content And the problem that the garbage is easy to form agglomerates and agglomerates when it is dried and burned
