Environment-friendly efficient waste incinerator

Abstract

The invention discloses an environment-friendly efficient waste incinerator. The environment-friendly efficient waste incinerator comprises a lower incinerator body part, an upper incinerator body part, an internal chimney, a base, an incinerator cover and an external chimney. The upper incinerator body part and the lower incinerator body part of an incinerator body are welded into a whole. The internal chimney is arranged in the middle of the lower incinerator body part and the middle of the upper incinerator body part. A combustion chamber is formed by the lower incinerator body part and the internal chimney. Refractory bricks are arranged on the periphery of the lower incinerator body part and the periphery of the upper incinerator body part. The bottom end of the lower incinerator body part is connected with the base. Both the upper surface and the lower surface of the base are open. The incinerator cover is arranged on the upper incinerator body part. The external chimney is arranged at the top of the incinerator cover in a connected mode. A water tank is arranged outside the lower incinerator body part. An oil tank is further arranged in the water tank. A water pipe and an oil pipe are arranged in the internal chimney. The water pipe is communicated with the water tank. The oil pipe is communicated with the oil tank. According to the environment-friendly efficient waste incinerator, oil in the oil pipe can be gasified by means of heat generated during waste combustion, so that waste on the upper portion of the incinerator body can be combusted for the second time, continuous waste combustion is achieved, incineration is thorough and rapid, and the incineration effect is good; pollution to the environment is small, and the environment-friendly efficient waste incinerator is suitable for waste treatment in village and town 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.
