Description

A solid waste incineration tower based on environmental protection technology

technical field

The invention relates to the technical field of waste incineration, in particular to a solid waste incineration tower based on environmental protection technology.

Background technique

Garbage is unwanted or useless solid and fluid matter. In densely populated cities, garbage disposal is a headache. Common way is to send to landfill after collecting for landfill treatment, or burn with incinerator. But both create environmental concerns, and ending overconsumption could further reduce landfill saturation. Waste disposal in landfills not only pollutes the groundwater and emits a bad smell, but many cities have less and less landfill area. Incineration inevitably produces toxic gases that harm living organisms. Most cities are researching ways to reduce waste and encourage recycling.

Garbage is solid waste generated in human daily life and production. It has complex and diverse components, and is polluting, resourceful, and social. It needs to be harmless, resourceful, reduced, and socialized. If it cannot be disposed of properly, It will pollute the environment, affect environmental sanitation, waste resources, destroy production and living safety, and destroy social harmony.

Garbage disposal is to quickly remove garbage and carry out harmless treatment. Usually, the recyclable garbage is recycled and then the unnecessary garbage is incinerated. However, the existing garbage incinerators are not environmentally friendly, and the incineration efficiency is low. Waste Energy, the incineration flue gas is directly discharged, which is harmful to the air.
