Garbage liquefaction specific gravity separation method and apparatus for biomass and composting

摘要

PPROBLEM TO BE SOLVED: To solve such a problem that garbage can not easily be fractionated even using magnetism, a net, wind power, and water stream, or only by specific gravity difference because of the viscosity and the intricately interwinding morphological feature of the garbage in fractionation of vinyl, glass, and metal from the garbage. PSOLUTION: In Fig.1, a method comprises the steps of: feeding garbage into an apparatus 1 for fractionating garbage by liquefaction and specific gravity difference; removing suspended solids of vinyl in a removing device 9 by adding water; liquefying the resulting material in a crashing and pulverizing device 11; stirring and separating it in a stirring device 2 by specific gravity difference; and fractionating the glass and the metal in a separating device 12.
