Solid waste crushing treatment system

Abstract

The invention provides a solid waste crushing treatment system. The solid waste crushing treatment system comprises a first crushing device, a second crushing device and a magnetic separation device; the first crushing device is used for primary crushing of solid waste to generate first particles, and the particle size of at least 90% of the first particles is smaller than or equal to 150 mm; the second crushing device is used for crushing the first particles to generate second particles, and the particle size of the second particles is smaller than or equal to 100 mm; and the magnetic separation device is arranged between the first crushing device and the second crushing device and is used for removing metal impurities in the first particles. According to the solid waste crushing treatment system, the solid waste crushed particles generated by the system are stable in combustion, and the production process is high in automation degree and environmentally friendly.

Description

technical field [0001] The present disclosure relates to the field of garbage treatment, in particular to a solid garbage crushing and treatment system. Background technique [0002] At present, in the solid waste treatment system in the domestic market, general industrial solid waste is directly sent to incineration plants or landfills without crushing and other treatment links. However, when solid waste contains non-combustible substances, the incineration site cannot directly receive incineration. , Secondly, the unbroken industrial solid waste is very unstable and difficult to incinerate, while the incinerated solid waste produces more residues and is more difficult to deal with. [0003] For the treatment of large-volume garbage, a simple crusher is generally used and a magnetic separation process is set up for the crushed garbage to select metal impurities, but the crushing effect is poor, the particle size cannot be effectively controlled, and the output volume is lar...

AI Technical Summary

Problems solved by technology

[0002] At present, in the solid waste treatment system in the domestic market, general industrial solid waste goes directly to incineration plants or landfills without crushing and other treatment links, but when When solid waste contains non-combustible substances, the incineration site cannot directly receive incineration. Secondly, the combustion of unbroken industrial solid waste is very unstable and difficult to incinerate. For the incinerated solid waste, there are more residues and it is difficult to process. larger

[0003]For large-volume garbage treatment, a simple crusher is generally used and a magnetic separation process is set up for the crushed garbage to select metal impurities, but the crushing effect is poor. Particle size cannot be effectively controlled, and the output volume is large, and the screening rate of metal impurities is low, which cannot be effectively converted into alternative fuels

The solid waste for landscaping is also crushed by a simple crusher. Since the volume of the discharged particles cannot be controlled, it cannot be directly used as an alternative fuel
