High pressure loss fire grate segment structure device for garbage incinerator

Abstract

The invention relates to a high pressure loss fire grate segment structure device for a garbage incinerator. The device comprises a fixed fire grate segment and a movable fire grate segment. The fixed fire grate segment and the movable fire grate segment each comprise a fire grate segment supporting block, a supporting block check block, supporting structural steel, a structural steel check block and a base, wherein the supporting structural steel and the structural steel check block are mounted on the base and are fixed through a bolt, and the supporting block and the supporting block check block are arranged on the top of the supporting structural steel, and are fixed through a bolt. Dual supporting parts are arranged on the base of each fire grate segment side by side; the fixed fire grate segment and the movable fire grate segment are arranged in a staggered manner, the base of the movable fire grate segment moves front and back through a drive unit, the movable fire grate segment does front-and-back reciprocated motion from bottom to top, waste moving and turnover can be achieved, the fire grate segment fixing manner is changed, the fire grate segment tail structural manner is improved, it is ensured that a fire grate segment body is not prone to tilting, meanwhile, detaching and overhauling are easy, the fire grate segment air inlet manner is changed, transverse air inlet is uniform, high pressure loss characteristics are formed, and combustion efficiency of the fire grate segment incinerator is improved.

Description

technical field [0001] The invention belongs to the technical field of waste incineration power generation, and in particular relates to a high-voltage-loss fire grate structure device for a waste incinerator. Background technique [0002] With the rapid development of domestic urbanization, waste disposal methods that can save land resources, make waste disposal harmless, reduce and recycle have been more and more widely used, among which mechanical grate furnace is the most widely used The most extensive waste incineration technology. [0003] The most important component of a waste incinerator is the incinerator grate system. The grate system is responsible for the transportation of garbage in the furnace, the disturbance of air and garbage, so as to improve the combustion efficiency. [0004] Most of the existing grate systems adopt reciprocating grate, and the grate is composed of movable grate pieces and fixed grate pieces arranged alternately. There are various typ...

AI Technical Summary

Problems solved by technology

[0007] In order to ensure the ventilation rate of the grate, openings are added between the grate or inside the grate. If the opening is too small, the combustion air cannot quickly penetrate the garbage layer, which will affect the combustion; if the opening is too large, the waste incinerator will leak slag If the rate rises sharply, it will not meet the requirement of 5% thermal burn reduction rate

[0008] In order to ensure the air intake and thermal expansion allowance in the gaps between the grate pieces, the grate pieces are usually connected by non-fastening, and high-melting point solid particles are also easily mixed in, and the grate pieces appear eccentrically worn, which aggravates the wear

The grate is not tightly connected, and even abnormally tilted during the process of stirring the garbage, directly exposed to the combustion air, the temperature of the combustion atmosphere is as high as 950 ℃ ~ 1150 ℃, which exceeds the temperature tolerance range of the grate, high temperature burning occurs, and even emergency shutdown Furnace; if the furnace is frequently shut down for maintenance, it will inevitably affect the production and operation of the waste incineration plant
