Abstract

A large-scale domestic waste incineration grate furnace relates to the field of waste incineration equipment, and comprises a drying grate (1), a combustion grate (2), and a burnout grate (3) which are arranged in a stepwise manner. The drying grate (1), the combustion grate (2), and the burnout grate (3) employ the same modular structure, and each include a grate supporting frame (4). Lateral frames (5) are symmetrically disposed on two sides of the grate supporting frame (4). The grate supporting frame between the lateral frames is provided with a plurality of modular incineration grate units (6) in a stepwise arrangement. The grate supporting frame (4), the lateral frames (5), and the modular incineration grate units (6) belonging to each of the drying grate (1), the combustion grate (2), and the burnout grate (3) all adopt a modular design. The domestic waste processing capacity of the incineration units may be modified by changing the number of the modular units. Each of the modular units can be operated independently, and the size of the structure thereof may be adjusted and modified according to actual needs.

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...
