Garbage incineration treatment method

Abstract

The invention discloses an incineration treatment method for wastes. A used waste incineration treatment unit comprises an incinerator and a waste gas treatment device, wherein fire bars of the incinerator are combined into a shape like a circular truncated cone with a higher middle and a lower peripheral part; a fire jetting device is arranged on a hearth below the fire bars, is connected with a fire feeding pipe of a burning device outside an incinerator body and is also connected with a gas returning pipe outside the incinerator body; a gas collecting device arranged above the fire bars is connected with the gas returning pipe outside the incinerator body; a water collecting device is arranged at the lower part of the gas returning pipe; and the waste gas treatment device consists of a gas separating device as well as a first-stage plasma treatment device, a second-stage plasma treatment device and a catalytic treatment device which are sequentially connected with the gas separating device by pipelines. The incineration treatment method for the wastes disclosed by the invention comprises the following steps of firstly, drying and preliminarily burning the wastes; after the wastes are sufficiently burnt in the incinerator, treating waste gases; and jointly incinerating all the wastes. The simplicity in operation is realized; the waste gas treatment device can be used for removing dust, water and oil, effectively degrading organic gases and eliminating foul odor; and exhausted gases completely reach national discharge standard.

Description

technical field [0001] The invention relates to garbage treatment, in particular to a garbage incineration treatment method. Background technique [0002] Garbage is what people leave behind in the process of life and production. The types of garbage include all items, so it is quite difficult to process. There are many types of garbage, difficult classification, and high cost of classification. When all kinds of garbage are incinerated together, the ones with high water content are not easy to burn fully (such as vegetable peels, kitchen waste and other domestic waste with high water content), and the smell produced when burning is also very unpleasant. Both plastic products There are all kinds of smells, such as the smell of animal meat, and the smell of animal meat. If the bad smell is not controlled, it can even spread and affect the surrounding range of several kilometers. If there is low-temperature combustion in the incineration process, carcinogens such as dioxins w...

Problems solved by technology

[0005] How to solve the problem of waste incineration, how to solve the waste gas treatment after incineration, and how to organically combine incineration with subsequent waste gas treatment are major issues in the field of waste incineration treatment. It is precisely because these problems have not been well solved, so The current garbage disposal is still not satisfactory, and the smog is still threatening the survival of human beings at any time
