A landfill mineralized waste sorting device and its application resource treatment system

Abstract

The invention discloses a mineralized waste sorting device for a landfill and a resourceful processing system applying the mineralized waste sorting device. The sorting device comprises a drum screen, combustible sorting equipment and cyclone winnowing equipment which are connected in series through a conveying mechanism. On the basis that the mineralized waste sorting device for the landfill is applied to the resourceful processing system, the resourceful processing system further comprises mineralized waste excavation equipment, conveying and storage equipment, drying equipment, smashing equipment and high-pressure extrusion equipment, wherein the mineralized waste excavation equipment and the conveying and storage equipment are arranged on the front section of the drum screen, and the drying equipment, the smashing equipment and the high-pressure extrusion equipment are sequentially arranged on the rear section of the cyclone winnowing equipment. By the adoption of the mineralized waste sorting device for the landfill and the resourceful processing system, combustible components and noncombustible components of mineralized waste can be truly sorted, separated and collected precisely, the metal recovery, humus nutrient soil covering and reutilization and energy utilization of combustibles for producing solid fuel are achieved, and the purposes that the service life of the landfill is prolonged, or commercial exploitation of soil is realized again, and the ecological environment is improved are achieved.

Description

technical field [0001] The invention belongs to the technology of sorting ore block garbage, and in particular relates to a sorting device for mineralized garbage in a landfill and an applied resource processing system. Background technique [0002] With the growing population and rapid economic development in China, according to statistics, my country produced about 200 million tons of municipal solid waste in 2016, and the annual growth rate has exceeded 10%. More than 90% of domestic solid waste is disposed of in centralized landfill. [0003] From the primitive and backward natural landfill of garbage to the sanitary landfill developed in modern times, landfill is a common method for human beings to dispose of garbage, which is simple and practical. At present, there are more than 3,000 landfills of a certain scale in China, and the garbage storage of simple domestic waste landfills over the years has exceeded 180 million tons, and there are more than 1,000 landfills tha...
