Description

An environmentally friendly waste incinerator

technical field

The invention relates to a garbage treatment device, in particular to an environment-friendly garbage incinerator.

Background technique

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 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. Therefore, the disposal method of landfill has been gradually replaced.

Compared with landfill disposal, waste incineration is a better disposal method. Through burning, not only the volume of garbage is reduced, but also the heat generated by burning can be used for energy recycling such as heating, and the ash after burning can be used to make bricks. During the use of the traditional waste incinerator, the waste is put on the grate in the incinerator for incineration. The composition of the waste is complex, and the combustible gas in the flue gas and the combustible matter in the fly ash cannot be completely incinerated, and finally discharged There are many harmful components in the flue gas, which will cause serious pollution to the environment.
