A staggered and forward-moving domestic waste incineration grate structure

Abstract

The invention relates to household garbage incineration equipment, in particular to the improvement of the structure of a staggered forward-push fire grate. The staggered forward-push household garbage incineration fire grate structure comprises three sections, namely, a drying section, a combustion section and an ash section, wherein each section of the fire grate has an independent drive system and has the fall; the fire grate comprises fixed fire grate bodies, sliding fire grate bodies, covering fire grate bodies and discharging fire grate bodies; the sliding fire grate bodies and the fixed fire grate bodies are arranged in a staggered manner, the sliding fire grate bodies driven by sliding fire grate beam slide on a support frame, the fixed fire grate bodies on fixed fire grate beams are kept static, the covering fire grate bodies are arranged in the front of all the sections of fire grate, and the discharging fire grate bodies are arranged at tails of all the sections of fire grate. By the aid of the fire grate structure, the garbage loosening effect is better, combustion is more uniform, the combustion condition is easier to adjust and control, the running power consumption is low, so that the air volume and the air pressure are controlled to be more ideal, dust produced after combustion is low in concentration and large in particle size, the slag leakage rate is low, and the structure is more suitable for complex garbage components.

Description

technical field [0001] The invention relates to a kind of domestic waste incineration equipment, especially the structural improvement of the staggered forward push fire grate. Background technique [0002] At present, most domestic waste incineration grates are mainly horizontally reversed, without agitation or crushing devices, resulting in insufficient waste crushing, and the air holes on the fire grate are easily blocked by waste, resulting in insufficient waste incineration and affecting the collection of waste. Subsequent landfill, and pollute the environment. [0003] The traditional longitudinal push grate, such as the Chinese patent CN201748438U, is suitable for the mechanical grate of municipal solid waste incineration, which is composed of grate pieces, movable grate beams and fixed grate beams; among them, the movable grate beams and grate pieces are jointly composed The movable furnace arrangement, the fixed grate beams and the grate pieces together form the fi...

Problems solved by technology

[0004] However, due to the gap between the above-mentioned sliding beam and the fixed beam, there are more ways for the combustion air to enter the furnace, which alleviates the clogging of the air holes. However, the fixed beam arranged longitudinally is in a static state, which will cause the garbage on the fixed beam to push Slow consequences, which affect the efficiency of waste incineration
