Garbage pretreatment and efficient recycling technology matched with garbage combustion system

Abstract

The invention discloses a garbage pretreatment and efficient recycling technology matched with a garbage combustion system. The garbage pretreatment and efficient recycling technology comprises the following steps: a, a garbage bag is broken open by a bag breaking machine; b, most leachate of household garbage subjected to bag breakage is drained by a leachate processing technology; c, after most leachate of household garbage is drained, the household garbage is screened and separated, and oversize products and undersize products are separated; d, the oversize products and the undersize products pass through a magnetic separation apparatus to separate and recycle ferromagnetic objects; e, the oversize products pass through a gravity winnowing apparatus to separate oversize heavy objects and oversize light objects; f, the oversize light objects pass through a waste and old plastic fine separation and recycling dry separator to separate waste plastics and oversize light impurities; g, the undersize products, the oversize heavy objects and the oversize light impurities are stirred, uniformly mixed and dried, and then enter an incinerator for incineration and power generation; and h, the separated waste plastics are processed by a splitting decomposition oil refining device. According to the garbage pretreatment and efficient recycling technology matched with a garbage combustion system, the household garbage incineration disposal has the characteristics of harmlessness, recycling, industrialization and the like.

Description

technical field [0001] The invention relates to the technical field of domestic waste treatment. Background technique [0002] At present, the annual output of domestic waste in my country is about 150 million tons, and it is increasing at a rate of 8% every year, while the annual stockpiling of waste in my country has reached more than 6 billion tons, occupying a large amount of land resources. It is estimated that among the 668 cities in my country, about two-thirds of them are surrounded by garbage. [0003] The existing domestic waste treatment and disposal modes mainly include landfill, incineration and composting, and the number of domestic waste recycling processes is also increasing, which is mainly affected by the following factors: (1) Technical practicability and reliability; (2) ) treatment costs and affordability; (3) environmental pollution and pollution control; (4) resource value and some special constraints, etc. [0004] From the perspective of infrastruc...
