A molding process and molding equipment for biomass derived fuel (rdf)

Abstract

The invention discloses a molding process and molding equipment for biomass-derived fuel (RDF), which sequentially include a mixer, a fine breaker, a screw extruder and a molding head on the screw extruder, and the molding head is provided with a discharge port; One end of the mixer is connected to the closed conveyor belt A, and the other end is an adjustable inclined outlet. The adjustable inclined outlet is connected to one end of the closed conveyor belt B, and the other end of the closed conveyor belt B is connected to one end of the fine crusher. The other end of the crusher communicates with the hopper through a closed conveyor belt C, the lower end of the hopper is a screw extruder, and the components are driven by a motor; a sodium hydroxide spray head is installed on the inner top of the mixer. Through this equipment and process method, the molding efficiency is higher, the density of the RDF fuel after molding can reach more than 1, the moisture content is lower, and the maintenance cost is lower.

Description

technical field [0001] The invention relates to a production process of biomass derived fuel (RDF), in particular to a molding process and molding equipment of biomass derived fuel (RDF). Background technique [0002] Biomass waste includes municipal solid waste, urban sludge, agricultural and forestry waste, medical waste, industrial organic waste, etc., and its equivalent is more than 8 times the energy used by all human beings. The above-mentioned wastes are crushed-air separation-screening-magnetic separation-crushing to a certain particle size, and pressed into biomass-derived fuel RDF (abbreviation of Refuse Derived Fuel), then the RDF has high calorific value, stable calorific value, It has the characteristics of complete pyrolysis, complete gasification, stable combustion, easy transportation, easy storage, no secondary pollution, no odor, and low emission of dioxins after combustion. [0003] The birth of biomass waste derived fuel (RDF) has undoubtedly brought vit...
