Garbage incineration equipment and garbage incineration process

Abstract

The invention discloses garbage incineration equipment. The garbage incineration equipment comprises a pretreatment device and an incineration furnace. The pretreatment device comprises a first shell.A controllable door is arranged in the first shell. A rotating part used for driving a material to rotate is arranged in a drying part. The outer portion of the rotating part is sleeved with a cylindrical heat conductor. A drain pipe is arranged in the position, located at the bottom of the drying part, of the first shell. A second rotary shaft is rotatably mounted on a bearing plate located at the bottom of a screening part. The screening plate is fixedly mounted on the second rotary shaft through a supporting frame. The incineration furnace comprises a second shell. A crushing device and afurnace chamber are arranged in the second shell from top to bottom in sequence. The bottom of the interior of the second shell is provided with an air compression pump. A combustor is mounted on oneside of the second shell. The invention further discloses a garbage incineration process adopting the garbage incineration equipment. The garbage incineration equipment and the garbage incineration process have the beneficial effects that the treatment efficiency is high, secondary pollution is not likely to occur, the heat recovery rate and reutilization rate are high, as the cost is low.

Description

technical field [0001] The invention relates to the technical field of solid waste treatment, in particular to waste incineration equipment and technology. Background technique [0002] At present, the quality of garbage in our country is poor, and the garbage classification is not done well enough. There are many incombustibles, high moisture content, and it is not easy to distinguish, resulting in insufficient combustion and easy to produce secondary pollution. [0003] In the prior art, Chinese patent CN103234205B provides a grate type incinerator, which includes a furnace body and a grate arranged in the furnace body, and also includes a stopper for preventing garbage from falling on the grate. There are perforations on the piece, and the baffle is arranged in the furnace body and above the grate. Through the setting of the baffle, the newly dropped garbage can be shelved on the baffle, so it will not directly drop on the fire grate to extinguish the fire on the fire ...

AI Technical Summary

Problems solved by technology

However, the garbage has not been treated, there is too much water, the larger garbage is not fully burned, and the exhaust heat is not fully utilized

Chinese patent CN105090979B provides a kind of garbage incinerator. The garbage incinerator includes a first furnace body, a second furnace body, a fan, an air induction part and a smoke exhaust pipe, and is provided with a feeding port and a slag discharge port. Improve the combustion efficiency and temperature of the waste incinerator, make the temperature in the waste incinerator reach 950 ℃ ~ 1100 ℃, reach the decomposition temperature of dioxin, reduce the emission of dioxin, but there are high treatment costs, Disadvantages such as high intake of cold air
