Forward pushing type household garbage incinerator grate

Abstract

A forward pushing type household garbage incinerator grate comprises a drying area, a first combustion area, a second combustion area and a burnout area. The inclination angle of the portion, in the drying area, of the incinerator grate is 12 degrees to 18 degrees, the inclination angles of the portions, in the combustion areas and the burnout area, of the incinerator grate are 5 degrees to 10 degrees. Each area of the incinerator grate is divided into 1-3 sections in the length direction, is divided into 1-2 air chamber areas in the width direction and is formed by a plurality of driving units. A fall of being about 1m is arranged between every two adjacent sections of incinerator grate, and cooling air is arranged at the fall. Each incinerator grate module comprises a fixing frame, movable beams, static beams, a driving system, a supporting roller, an incinerator grate segment, an incinerator grate segment support and the like. The movable beams and the static beams are alternately arranged in columns, the movable beams are driven by a swing device at the front end to move, and abrasion-resistant sliding plates at the rear ends of the movable beams roll on the supporting rollers.The front ends of the static beams are fixed through hooks, and the rear ends of the static beams are supported and fixed. Each incinerator grate module is independently driven, and a driving deviceis arranged on the outer side of a furnace wall. The forward pushing type household garbage incinerator grate is simple in structure, the primary air distribution is uniform, the combustion process isfully automatically controlled, the long-time continuous stable operation can be achieved, the heat efficiency is improved, and the emission concentration of secondary pollutants is reduced.

Description

technical field [0001] The invention relates to a domestic waste incineration grate, in particular to a forward push type domestic waste incineration grate with drop cooling. Background technique [0002] At present, the waste incineration grate at home and abroad is mainly divided into two types: reverse push and forward push. Among them, the reverse push grate has no drop, the garbage is not easy to break during the movement, and the garbage is not fully burned, and the position of the air holes of the grate blades is greatly worn during the movement of the reverse push grate, and large pieces of unburned garbage are easy to pass through the air holes. Enter the grate plenum. [0003] The traditional forward-moving domestic waste incineration grate is divided into three areas: the drying area, the burning area and the burning area, and there is a drop between each area. However, the forward grate is easy to coke at the drop during use, and the deterioration of the coking...

AI Technical Summary

Problems solved by technology

However, the forward grate is easy to coke at the drop during use, and the deterioration of the coking will destroy the refractory material at the drop and affect the normal combustion of garbage

In addition to entering the furnace through the upper air holes of the grate pieces, the combustion air can also enter the furnace through the gaps between the grate pieces; however, due to the complex composition of the garbage, part of the molten material after combustion often blocks the upper air holes, thereby affecting the garbage collection. In addition, too many air holes on the upper part of the grate of the existing equipment often lead to an increase in the amount of slag leakage and an increase in the rate of slag thermal ignition loss, which is unfavorable

[0004] In addition, the temperature of the grate in the combustion zone of the existing equipment is relatively high, and there is usually no monitoring device for the temperature of the grate, which may easily cause some of the grate to be damaged due to excessive temperature
