Embodiment Construction

[0033] to combine figure 1, the present invention is used to realize the incinerator in the incineration treatment method of the domestic waste by electric control feeder 1, smoke outlet 2, distribution body 3, support plate 4, wind tower 5, furnace body 6, support column 7 Composed of electric vibrating discharger 8, the upper section of the furnace body 6 is in the shape of a vertical cylinder, and the lower section is in the shape of an inverted round platform. The furnace body with this structure can obtain the largest working volume in the most limited space. An electric control feeder 1 is arranged in the middle of the top of the upper section of the furnace body 6. The feeding port of the electric control feeder 1 is in the shape of a round table with a large upper part and a smaller bottom. The feeding port of the electric control feeder 1 is cylindrical and extends into Inside the furnace, it is very conducive to the feeding and unloading of garbage. The top of the u...

Abstract

The invention provides an incineration treatment method for domestic refuse. The method comprises: having an incinerator arranged between a rotary kiln and a decomposing furnace; introducing tertiary hot air into a wind tower of the incinerator and baking an incinerator body; crushing domestic refuse with the water content less than 20 percent into refuse material 50 to 80 millimeters in particle size and guiding the refuse material into the incinerator body through an electronic control feeder of the incinerator; allowing a material level meter to send a feedback signal to stop adding the refuse material when a refuse material layer is 50 millimeters away from a material separation body; drying the refuse material; burning, decomposing and gasifying organic substances in the refuse material through the tertiary hot air out of a multi-layer air outlet of a central air pipe; ensuring that the temperature in the incinerator body is above 850 DEG C; discharging produced flue gas to the decomposing furnace through a smoke outlet; ensuring that the decomposing furnace reaches a temperature of above 900 DEG C and is in an alkaline atmosphere; and further neutralizing acidic flue gas. Refuse ash-slag is discharged through an electrical vibrating material discharger, sent into the rotary kiln, and is taken as raw material burden for cement production to participate in calcination, so that the aim of treating domestic refuse in a 'harmless, amount-reducing and resource-recovering' way is achieved.

Description

technical field [0001] The invention belongs to the technical field of garbage treatment, in particular to an incineration treatment method for household garbage. Background technique [0002] The disposal of domestic waste is one of the most popular research topics in today's society. The country clearly puts forward the principle of "harmless, reduced, and resourceful" waste disposal. [0003] At present, the common treatment methods of domestic waste include incineration, landfill and biological method. [0004] The landfill method requires the construction of a large area of ​​landfill and the treatment of leachate, which requires a large investment, and there is also a hidden danger of secondary pollution caused by the leakage of the filtrate. [0005] The garbage biological method is to ferment domestic garbage. The process is complicated and the equipment performance requirements are high. It is suitable for the treatment of garbage with biodegradable organic matter ...
