Abstract

The invention relates to a method for preparing household garbage derived fuel. After bag breaking, screening and magnetic separation household garbage enters a biological pre-treatment bin to be subjected to protogenesis garbage dehydration and stabilization, pretreated garbage then enters a secondary separation section, processes such as screening, magnetic separation and winnowing are carried out to efficiently separate recyclable products from toxic and harmful products, and residual material with high organic matter content enters an aerobiotic compost bin. An aerobic composted production is directly broken, extruded and moulded to prepare the garbage derived fuel. The invention also discloses a device used for realizing the method. According to the method provided by the invention, garbage is dried and becomes harmless by adopting biological pre-treatment and a composting two-step method, and the garbage is taken as raw material of the derived fuel, the aim of reducing release of dioxin and heavy metal can be realized without adding a chloride solidifying agent or a bonding agent, energy recycling effect is good, and RDF has stable properties and high heat value after being extruded and moulded, so that the method provided by the invention has a wide application prospect.

Description

technical field

[0001] The invention belongs to the technical field of solid waste treatment and resource utilization, and in particular relates to a method and a device for producing high-quality garbage-derived fuel by using products after sorting and composting domestic garbage. Background technique

[0002] At present, the world's garbage production is increasing at a rate three times the average economic growth rate. The output of urban garbage in my country has accounted for more than 25% of the world's garbage production. The garbage siege has seriously affected the environmental quality and the health of residents. As early as the beginning of the 20th century, people discovered that waste resources can be used for heating, power generation, and driving cars. Waste is considered to be an inexhaustible "urban mineral deposit" with the greatest development potential and a "misplaced resource." , This is not only the deepening and deepening of the understanding of garba...
