Garbage refinement pretreatment system and method for garbage incineration power plant

Abstract

The invention discloses a garbage refinement pretreatment system and a method for a garbage incineration power plant, comprising a garbage storage pool and a sorting system, wherein the sorting systemcomprises a bag breaking machine, an intelligent sorting platform, a crusher and an extruder; a slurry outlet of the extruder is sequentially connected with a slurry pool and an oil-water separator;a solid outlet of the extruder is connected with a bouncing sieving machine; an oversize product outlet of the bouncing sieving machine is sequentially connected with a first magnetic separator, a first sorting machine, a disc sieving machine and a second sorting machine; the combustible material outlet of the second sorting machine is connected with a combustible storage bin; a screen underflow outlet of the bouncing sieving machine is sequentially connected with a second magnetic separator and a star disc sieving machine, and the combustible material outlet of the star disc sieving machine is connected with the combustible material storage bin. The pretreatment technology adopted by this system has advanced principle, good sorting effect; the sorting combustible material has high heat value and high single-line treatment capacity; therefore the pretreatment technology is a more optimized, more suitable, more economical and more reliable garbage refinement pretreatment technology.

Description

technical field [0001] The invention belongs to the technical field of waste incineration power generation, and in particular relates to a waste fine pretreatment system and method for a waste incineration power plant. Background technique [0002] Garbage is solid waste generated in human daily life and production. Due to its large discharge volume, complex and diverse components, and its polluting, resourceful and social nature, it needs harmless, resourceful, reduction and socialized treatment. If not handled properly, it will pollute the environment, affect environmental sanitation, waste resources, destroy production and living safety, and disrupt social harmony. Garbage disposal is to quickly remove garbage, and conduct harmless treatment, and finally make reasonable use of it. At present, the municipal solid waste treatment methods widely used at home and abroad mainly include sanitary landfill, high-temperature composting, and incineration. the difference. With th...

Problems solved by technology

With the development of the economy, the total amount of domestic waste continues to increase. The traditional landfill and composting process has gradually been unable to meet the waste treatment requirements due to its land occupation and environmental protection requirements. More and more waste is treated by incineration. Incineration power plants also came into being

In the existing technology, the process of waste incineration power generation is to discharge the collected garbage into the garbage pit, and then directly put it into the furnace for incineration after a period of heap filtration. The classification effect of domestic waste is poor, and when it is incinerated, the slag, metal and large pieces of inert waste in the waste can easily cause the failure of the incinerator and affect the normal operation of the waste-to-energy plant. The efficiency of power generation is low, and the content of dioxin produced by incineration is relatively large, which seriously pollutes the air environment and poses a threat to human health
