An environmentally friendly and efficient waste incinerator

Abstract

An environmentally friendly and efficient waste incinerator, comprising a lower furnace body, an upper furnace body, an inner chimney, a base, a furnace cover and an outer chimney; the upper furnace body and the lower furnace body of the furnace body are welded as one, and the lower furnace body and the upper furnace body An inner chimney is set in the middle of the furnace body, and the lower furnace body and the inner chimney form a combustion chamber. The lower furnace body and the upper furnace body are surrounded by refractory bricks. The bottom end of the lower furnace body is connected to the base, and the upper and lower sides of the base are open; A furnace cover is provided above the upper furnace body, and an outer chimney is connected to the top of the furnace cover; a water tank is provided outside the lower furnace body, and an oil tank is also provided in the water tank; a water pipe and an oil pipe are provided in the inner chimney; The water pipe communicates with the water tank; the oil pipe communicates with the oil tank. The invention can use the heat generated in the burning of garbage to gasify the oil in the oil pipe, thereby performing secondary combustion on the garbage above the furnace body, forming continuous burning of garbage, complete and fast burning, and good burning effect; the invention has little environmental pollution , suitable for garbage disposal in township communities, schools and hospitals.

Description

technical field [0001] The invention relates to a garbage treatment device, in particular to an environment-friendly and high-efficiency garbage incinerator. Background technique [0002] With the continuous development of the economy, the amount of domestic waste generated in towns and villages has also doubled every year. The traditional way of garbage disposal is to build a landfill to landfill the garbage. However, there are many defects in garbage landfill: first, the construction of garbage landfill takes up a lot of land, land is a non-renewable resource, and land resources are relatively tight; second, it pollutes the environment and increases management costs; After organic matter and batteries enter the landfill, the toxic leachate produced will seriously pollute the soil and groundwater. From the perspective of environmental protection, it is necessary to establish a landfill leachate anti-seepage, collection and treatment system. This will increase the technica...

Problems solved by technology

However, there are many defects in garbage landfill: first, the construction of garbage landfill takes up a lot of land, land is a non-renewable resource, and land resources are relatively tight; second, it pollutes the environment and increases management costs; After organic matter and batteries enter the landfill, the toxic leachate produced will seriously pollute the soil and groundwater. From the perspective of environmental protection, it is necessary to establish a landfill leachate anti-seepage, collection and treatment system. This will increase the technical difficulty, but also increase the investment, the landfill operation is complicated, and the management is difficult. In addition, the methane, hydrogen sulfide and other wastes in the landfill must also be treated to ensure that the explosion-proof and environmental protection requirements are met; 3. Waste of resources, A large amount of garbage is piled up in landfills, and some of the materials and energy cannot be used, which causes a waste of resources to a certain extent.

During the use of traditional garbage incinerators, garbage is put on the grate in the incinerator for incineration. However, when the garbage on the grate is burning, the newly put in garbage instantly covers the burning garbage. It is easy to extinguish the flame, resulting in unstable temperature in the furnace, insufficient garbage incineration, and insufficient garbage incineration will easily produce harmful gases

[0004] At the same time, the composition of the garbage is complex, and various combustibles have different properties, which makes the phenomenon of clinker, slag, sintering and other phenomena during the incineration process of the garbage, and the combustion rate is low.

The combustible gas in the flue gas and the combustible matter in the fly ash cannot be completely incinerated, and there are many harmful components in the finally discharged flue gas, which pollutes the environment

Garbage is sometimes incompletely burned, and black smoke will be generated due to incomplete combustion, causing secondary pollution to the environment. At the same time, due to the high temperature, the combustion furnace oxidizes quickly and has a short life, and the heat generated by combustion is not used.
