Method and device for preparing novel fuel from municipal domestic waste completely

Abstract

The invention relates to a method and a device for preparing novel fuel from municipal domestic waste completely and belongs to environmental protection on energy sources. The method comprises the following steps: separating out reusable substances such as plastic, metal and glass bottles from the municipal domestic waste serving as the only raw material; removing unrecoverable substances such as stones, bricks and cement; using the residual garbage as the raw materials of the novel fuel; breaking bags; sorting; sieving; drying; and performing extrusion molding to obtain the novel fuel. The method and the device can solve the problems of treatment and comprehensive utilization of municipal domestic waste. The fuel product can replace the resources such as solid combustible mineral coal, coke and the like, becomes a substituted energy product for large-scale thermal power plant and domestic fuel, is an important energy replacement and supplement measure, and has very important social and economic significance.

Description

technical field [0001] The invention relates to energy and environmental protection, in particular to a waste fuel product, especially a method and device for using renewable energy technology to solve the harmless treatment of urban domestic waste and make it a new type of fuel made entirely from urban domestic waste . Background technique [0002] At present, domestic and foreign municipal solid waste treatment methods mainly adopt landfill method, incineration method, biogas fermentation method and classification treatment method. Among them, the burial method directly buries the garbage underground, occupies a large piece of land, makes the land abandoned, and causes the land pollution of the land, which belongs to the elimination method; the incineration method treats the garbage pollutes the atmosphere and produces dioxins Carcinogenic gas, this method belongs to the "do not use" method; the biogas fermentation method separates the garbage and puts it into the ferment...

AI Technical Summary

Problems solved by technology

A large number of products of this new type of fuel are preferentially used in thermal power plants to replace raw coal, and can also be used in small boiler rooms and civilian use. It has realized a new type of fuel made entirely of municipal solid waste as raw materials and certain production processes and devices. It has truly transformed municipal solid waste into renewable resources without adding any solid combustible minerals, which not only eliminates the pollution of municipal solid waste, solves the current problem of urban waste occupying land, but also realizes the "turning urban solid waste into waste" by people for many years. The dream of reusing treasures is a major pioneering work for the benefit of mankind
