Fluidized bed microwave pyrolysis rural domestic garbage device and use method thereof

Abstract

The invention discloses a fluidized bed microwave pyrolysis rural domestic garbage device and a use method thereof. The fluidized bed microwave pyrolysis rural domestic garbage device comprises a roller dryer, a chain crusher and a spiral feeder, wherein the roller dryer is connected with the chain crusher; the chain crusher is connected with a feed port of a fluidized pyrolysis chamber through the spiral feeder; a discharge port of the fluidized pyrolysis chamber is connected with a cyclone separator; the top end of the cyclone separator is connected with a dust remover, and a solid outlet atthe bottom end of the cyclone separator is connected with the fluidized pyrolysis chamber; microwave reflection diffusion cavities are symmetrically arranged on the left side and the right side of the fluidized pyrolysis chamber; and microwave waveguides are connected with a microwave generator and uniformly arranged in the longitudinal direction of the microwave reflection diffusion cavities. The use method comprises the steps of drying, crushing, and vulcanizing pyrolysis. According to the device and the method, domestic garbage can be efficiently treated, no secondary pollution is generated, the garbage pyrolysis is more thorough, and the treatment efficiency is higher.

Description

technical field [0001] The invention relates to a device and method, in particular to a device and method for microwave pyrolysis of rural domestic garbage in a fluidized bed. Background technique [0002] With the development of social economy, the living standard of rural people has been continuously improved, but it has also brought some problems. The problem of domestic waste in rural areas is becoming more and more serious. Domestic waste in rural areas not only affects the appearance of villages, but more seriously pollutes the living environment in rural areas and damages people's health. It can be seen that the garbage problem in rural areas has become a prominent factor hindering the sustainable development of rural social economy. Therefore, how to properly and effectively dispose of rural domestic waste has become an important task in the construction of new countryside. [0003] At present, the disposal methods of rural domestic waste mainly include landfill, c...

Problems solved by technology

Landfill treatment requires a large amount of land. At the same time, harmful components in garbage will also cause serious pollution to the atmosphere, soil and water sources, which not only destroys the ecological environment, but also seriously endangers human health; The organic content of the garbage is relatively high, and the composting treatment cannot be reduced, and still needs a large amount of land; the essence of incineration is to burn the garbage in an incinerator, but due to the existence of oxygen, the chlorine-containing organic matter in the garbage will inevitably be produced and difficult to decompose Dioxin, a highly toxic substance, has become a bottleneck restricting the application of waste incineration

The existing waste treatment adopts fluidized bed incinerator, and the fluidized gas is passed upwards into the fluidized bed incinerator through the gas distribution pipe at the bottom, so that the temperature in the incinerator is uneven, and the temperature in the upper part is low and the temperature in the lower part is high. And incineration is easy to produce dust, causing secondary pollution
