Problems solved by technology

However, due to the particularity of waste components in my country and the weak research foundation in grate incineration technology and equipment development, most of the incineration grate furnaces in my country currently have many problems, such as insufficient fuel mixing and insufficient combustion leading to thermal efficiency. Low, high repair and maintenance costs for the grate system

Abstract

The invention discloses a novel high-efficiency vaporizing combustion compound furnace grate device with a slag disintegrating function. The traditional incinerator has the disadvantages of lower heat efficiency and high repairing and maintenance cost of a furnace grate due to poor fuel mixture and insufficient combustion. The novel high-efficiency vaporizing combustion compound furnace grate device with the slag disintegrating function adopts a two-section compound structure, wherein on the front section of a reciprocating type furnace grate, wastes are dried, vaporized and partially burned; and the unburned parts fall on a back-end rotary furnace grate device to be extruded, crushed and fully mixed to be burned completely. The reciprocating type furnace grate adopts a multi-air-port segmental air distribution way for reasonable air distribution; the heat radiation on the furnace grate is increased due to a long back arch, thereby facilitating the firing of wastes with low heat values. The novel high-efficiency vaporizing combustion compound furnace grate device with the slag disintegrating function is adopted to effectively improve the disadvantages of poor mixing effect and low burn-off rate of the traditional furnace grate incineration device, and meanwhile, the area of a furnace grate bar with high temperature resistance can be reduced, and the investment is reduced.

Description

technical field [0001] The invention belongs to the field of environmental engineering, in particular to a novel high-efficiency gasification combustion composite fire grate device with the function of crushing slag. Background technique [0002] At present, incineration is a very effective method of waste disposal, which can maximize the reduction, harmlessness and resource utilization of urban domestic waste. Among the many waste incineration equipment, the grate furnace is a main type of furnace. At present, most of the grate furnaces in our country either learn from the existing incinerators abroad, introduce or imitate foreign furnace types or equipment systems; or use general coal-fired boilers or other industrial furnaces as a reference to transplant these combustion technologies and processes. Carry out waste incineration. However, due to the particularity of waste components in my country and the weak research foundation of grate incineration technology and equipm...
