Abstract

The invention relates to a large-scale domestic waste incineration grate furnace and relates to the field of waste incineration equipment. The large-scale domestic waste incineration grate furnace comprises a drying section grate, a combustion section grate and a burnout section grate which are arranged in a stepped manner. The drying section grate, the combustion section grate and the burnout section grate are of the same modular structure and each comprises a grate support frame. Side frame bodies are symmetrically arranged on the two sides of each grate support frame, and multiple modular incineration grate units which are arranged in a stepped manner are arranged on the portion, between the side frame bodies, of each grate support frame. A modular design is adopted for each of the grate support frames, the side frame bodies and the modular incineration grate units of the drying section grate, the combustion section grate and the burnout section grate. The domestic waste treatment capacity of the incineration units is changed by changing the number of the modular units, each modular unit has independent operating capacity, and the structural size of the large-scale domestic waste incineration grate furnace can be adjusted and altered according to the actual demands.

Description

technical field [0001] The invention relates to the field of waste incineration equipment, in particular to a large-scale domestic waste incineration grate furnace. Background technique [0002] Waste incineration treatment has the advantages of reduction and harmlessness, resource utilization of waste heat energy, and reduction of secondary pollution, etc., which meets the requirements of my country's rapid and sustainable economic development strategy; at present, my country's urban waste incineration mainly adopts grate incineration Furnaces and grate-type incinerators come in various forms, and their applications account for more than 80% of the total waste incineration market in the world. [0003] At present, the daily processing capacity of domestic waste incineration grate furnaces is mainly between 100 tons and 500 tons. When dealing with domestic waste with high moisture and low calorific value, there is a common problem of insufficient combustion of waste in the f...
