The invention discloses a waste incineration system. The waste incineration system comprises a drying cracking furnace, a high-temperature gasification furnace, a peroxide burnout furnace and a burnout chamber arranged in sequence; waste is thrown into the drying cracking furnace, the waste on a drying conveying fire grate is dried, broken and partially cracked and then falls into a fluidization cracking zone at the top of a fluidization cracking air distribution chamber through gaps of the fire grate to conduct cracking reaction with air, and generated high-temperature cracked gas enters thehigh-temperature gasification furnace; in the high-temperature gasification furnace, cracked solid products conduct gasification reaction with air, the cracked gas entering the gasification furnace and water vapor conduct reforming reaction with high-temperature coke and reaction gas in the high-temperature gasification furnace, reaction gas easy to burn out is generated and enters the burnout chamber, and generated gasification reaction slag enters the peroxide burnout furnace; in the peroxide burnout furnace, gasification reaction slag reacts with air to burn out, and generated peroxide smoke enters the burnout chamber; and in the burnout chamber, high-temperature gasification reaction gas and the high-temperature peroxide smoke are subjected to mixed combustion, and it is ensured that dioxin is sufficiently removed.
Description
technical field [0001] The invention relates to the technical field of waste incineration power generation equipment and its supporting facilities, in particular to a waste incineration system. Background technique [0002] With the improvement of residents' awareness of environmental protection and the increasingly strict management of pollution emission control, the cleanliness requirements of waste harmless treatment technology are also gradually upgraded. [0003] At present, the harmless treatment of garbage mainly uses garbage incineration to generate electricity. After decades of technological development and accumulation of engineering experience, domestic waste-to-energy technology has reached a relatively good level. However, due to the special complexity of the waste, there are still problems such as slagging in the furnace, corrosion of the heating surface, high pollutant emissions, difficulty in controlling dioxins, and low power generation efficiency.
