Abstract

The invention relates to a double-hopper and double-fuel-layer layer-burning incineration device for village and town domestic garbage. The double-hopper and double-fuel-layer layer-burning incineration device for the village and town domestic garbage aims at solving the problem that an existing incineration device is not suitable for combusting the village and town domestic garbage, and comprises a chain fire grate, a briquetted coal feed hopper, a pre-combustion chamber, a pre-combustion chamber flue, a domestic garbage hopper and a hearth provided with a front arch and a rear arch. Briquetted coal entering the briquetted coal feeding hopper can be pre-ignited in the pre-combustion chamber, an ignited coal layer is formed on the chain fire grate, the domestic garbage in the garbage hopper falls onto the ignited coal layer, coal which is not ignited is located between the ignited coal and high-temperature flue gas of the hearth, two-side ignition is achieved, and it is ensured that the domestic garbage is ignited in time. Meanwhile, by means of heat generated by combustion of the briquetted coal on the lower layer, the temperature of the hearth can be raised, and it is ensured that combustion of the domestic garbage is stable. The double-hopper and double-fuel-layer layer-burning incineration device is applied to the field of combustion of the village and town domestic garbage.

Description

technical field [0001] The invention relates to a double-hopper double-fuel-layer layer combustion and incineration device for domestic garbage in townships. Background technique [0002] According to the survey, the average amount of domestic waste generated per person in rural areas in my country is 0.86kg per day, and a total of about 300 million tons of rural domestic waste is produced throughout the year. In 2005, nearly 50% of urban domestic waste in my country failed to be harmlessly treated and was finally Moved to rural areas. However, my country's rural environmental protection facilities are basically zero, and rural domestic garbage cannot be properly disposed of. Every year, about 120 million tons of garbage can only be piled in the open air. Therefore, realizing the harmless, reduced, and resourceful treatment of rural domestic waste is related to the national economy and the people's livelihood, and is one of the important contents of my country's sustainable ...
