Reciprocating grate furnace with two-section-reverse-acting and one-section-forward-acting grate

Abstract

The invention provides a reciprocating grate furnace with a two-section-reverse-acting and one-section-forward-acting grate. The reciprocating grate furnace with the two-section-reverse-acting and one-section-forward-acting grate provided by the invention comprises a feeding system, a hydraulic device, a grate, an automatic grate control system, a slag discharge device, an air chamber and an ash-placing channel, wherein the grate is divided into a drying section, a combustion section and a burnout section in sequence from top to bottom; a height difference is reserved between every two sections; both the grate bodies of the drying section and the combustion section are in a reverse-acting type; and the grate body of the burnout section is in a forward-acting type. By the reciprocating grate furnace adopting a two-section-reverse-acting and one-section-forward-acting grate structure implemented by the invention, the problems that the conventional mechanical grate furnace is inadequate in drying and incomplete in stirring and scattering, and agglomerates are easily formed during drying and combusting can be solved; the waste incineration efficiency can be improved effectively; the incineration cost can be reduced; and the reciprocating grate furnace is applicable to incinerate the waste with high moisture content and a low calorific value.

Description

technical field [0001] The patent of the present invention relates to a new type of grate furnace waste incineration treatment equipment, especially a reciprocating grate furnace with a design structure of two sections of reverse push and one section of forward push, which is suitable for high moisture content and low calorific value. Incineration of garbage. Background technique [0002] Mechanical grate incinerator (hereinafter referred to as mechanical grate furnace) is the furnace type with the longest development history and the most widely used. Its application accounts for more than 80% of the total waste incineration market in the world. The biggest advantage of this type of furnace is its mature technology, stable and reliable operation, and wide adaptability. Most solid waste can be directly incinerated without any pretreatment It is especially suitable for the characteristics of high moisture content and low calorific value of waste in small and medium-sized citi...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide a reciprocating grate furnace with two sections of reverse push type and one section of forward push type grate, which is suitable for incinerating garbage with high moisture content and low calorific value, and can solve the problem of drying traditional mechanical grate furnaces. Sufficient, incomplete agitation and easy agglomeration during drying and burning, which can effectively improve the efficiency of waste incineration and reduce incineration costs
