Clean high-temperature co-firing furnace for household waste disposal

Abstract

The invention discloses a clean high-temperature co-firing furnace for household waste disposal. The clean high-temperature co-firing furnace for household waste disposal comprises a first burning chamber for waste (a) and a second burning chamber for flue gas (b), wherein the first burning chamber for waste (a) is covered by refractory materials, and the second burning chamber for flue gas (b) iscovered by a steel structure. The first burning chamber for waste (a) comprises a feeding inlet (1), a first burning chamber hearth (2), a fire grate (3), a primary air inlet (4), a slag collection pit (5), a slag removal port (6). The second burning chamber for flue gas (b) comprises a second burning chamber hearth (7), a secondary air inlet (8), an ash removal port (9), a flue gas port (10) anda partition wall (11). The first burning chamber for waste (a) and the second burning chamber for flue gas (b) are connected through a flue gas channel (12) made of refractory materials. The clean high-temperature co-firing furnace for household waste disposal adopts the grate-firing technology, and is complete in waste incineration, high in disposal efficiency, capable of carrying out feeding and stably running, and low in quantity of generated secondary pollutants; and when the furnace is used for disposing the household waste in remote villages and small towns, and factories and the like,the waste collection and transportation cost is reduced, and the good human settlement can be created, and therefore, the furnace is wide in application range.

Description

technical field [0001] The invention belongs to the technical field of harmless treatment of domestic garbage, and in particular relates to a garbage incineration device, in particular to a clean high-temperature co-combustion furnace for processing domestic garbage. Background technique [0002] In rural areas of our country, with the improvement of people's living standards, the amount of garbage generated is increasing year by year, and the phenomenon of dumping garbage at will and surrounding villages with garbage has not been completely solved. According to statistics from the Ministry of Housing and Urban-Rural Development, the annual volume of urban garbage in my country is 179 million tons, and the annual output of rural garbage is about 150 million tons. The urban garbage disposal rate can reach 90%, while the rural garbage disposal rate is only about 50%. The random dumping of garbage not only affects the sanitation and living environment of the countryside, but th...

AI Technical Summary

Problems solved by technology

However, the existing waste incineration facilities in the market generally have problems of insufficient combustion and incomplete treatment of toxic and harmful substances in the process of processing primary domestic waste. For example, incomplete combustion of flue gas produces tar and other difficult-to-handle secondary pollutants.
