Solid waste combustion system

Abstract

The invention provides a solid waste combustion system. The solid waste combustion system comprises a squeezing and water removing device, a screening device, a crushing device, a drying device, a combustion device and a smoke treating device, wherein the squeezing and water removing device comprises a waste feeding hopper; the feeding hopper is connected with a roller by a pressure conveying belt; the crushing device comprises a crusher and a shaking type screening net located on the bottom of the crusher; the combustion device comprises a hearth; the outer part of the hearth is connected with the feeding hopper and dried wastes are conveyed to the feeding hopper by a drying device conveying belt; a spiral conveying impeller is mounted on the connection part of the feeding hopper and the hearth; the hearth is internally provided with an agitation device; the smoke treating device is connected with the hearth; an opening is formed in the connection part of the hearth and the smoke treating device; the smoke treating device comprises a dust removing device and a desulfuration and deodorization device. The solid waste combustion system provided by the invention is high in combustion efficiency; the treated wastes can be utilized sufficiently so that the resource utilization rate is improved and a working process is environment-friendly and pollution-free.

Description

technical field [0001] The invention relates to the technical field of solid waste incineration, in particular to a solid waste incineration system. Background technique [0002] Solid waste includes: urban road cleaning garbage, domestic garbage, catering garbage, medical waste, agricultural product processing waste, feces, waste plastics, tires, organic sludge and hazardous waste such as tanning sludge, electroplating sludge, printing and dyeing sludge etc. The disposal of these solid wastes has been a major problem that has plagued people's lives for many years. Over the years, people first adopted the landfill method. Later, people found that the landfilled waste cannot change the nature of the waste, and it will take up a lot of space. Open space, especially garbage such as plastic bags, cannot change its nature after being landfilled. Not much, will produce new rubbish pollution source again at the same time and come to an end. Later, the method of incineration was ...

Problems solved by technology

The disposal of these solid wastes has been a major problem that has plagued people's lives for many years. Over the years, people first adopted the landfill method. Later, people found that the landfilled waste cannot change the nature of the waste, and it will take up a lot of space. Open space, especially garbage such as plastic bags, cannot change its nature after being landfilled. Not much, at the same time will produce new sources of garbage pollution and come to an end

Later, the method of incineration was used. It is relatively thorough to use this method to dispose of garbage. However, the flue gas in the solid waste incinerator is discharged into the atmosphere through the chimney. Due to the high cost of flue gas treatment and operation or Due to the lack of maintenance of the flue gas treatment system and other reasons, a large amount of flue gas containing toxic and harmful gases and fly ash is discharged, causing serious pollution to the ambient air, water and soil. The long-term emission of these flue gases will endanger the living environment of human beings

[0003] Most of the garbage contains a lot of water. Due to the high water content, the cost of incineration is high and the air pollution is also great. Therefore, it is imperative to improve the technology of incineration of garbage.
