Problems solved by technology

At present, my country lacks and does not have the process, personnel, equipment, and technical conditions for the classified demolition, classified stacking, and classified treatment of building materials. Most of the construction solid waste treatment and disposal methods in our country can only be transported to the suburbs and remote areas. Landfilling and stacking, the plants that form the construction solid waste treatment and disposal area are difficult to grow, and the harmful substances contained (harmful metal ions, germs and microorganisms) seriously pollute the groundwater. Lead to serious soil, air, water pollution and disease prevalence in the area where construction solid waste is treated and disposed

Embodiment 1

[0014] A construction material solid waste recycling process, specifically comprising the following steps:

[0015] 1) Preliminary crushing: use a crusher to crush the construction solid waste to particles smaller than 1.5 cm;

[0016] 2) Screening: the organic solid waste particles in the pulverized particles are selected by winnowing method, and the remaining particles are inorganic solid waste particles, and the organic solid waste particles and inorganic solid waste particles are stored separately;

[0017] 3) Re-crushing: Use Raymond mill to grind the inorganic solid waste particles until the powder passes through a 60-mesh sieve, and send the powder into the homogenization bin for homogenization to obtain inorganic solid waste powder and organic solid waste After the metal is removed from the particles, they are shredded by a shredder, and the organic solid waste particles are ground into a powder that passes through a 40-mesh sieve using a disc mill, and the organic sol...

Abstract

The invention relates to a resourceful treatment process for solid wastes of building materials. The resourceful treatment process comprises the following concrete steps: 1) preliminary crushing; 2) screening; 3) crushing again; 4) weighing; 5) manufacturing of a green body; and 6) firing of ceramic. The resourceful treatment process provided by the invention has the following advantages: large-scale, batch and rapid treatment and disposal for the solid wastes like building solid wastes can be realized; complete harmlessness and permanent curing of toxic and harmful substances can be realized;the process has the advantages of simplicity, good operability, high reliability, less equipment investment, short production cycle, high production efficiency, energy conservation and environmentalprotection; and the ceramic prepared by using the process provided by the invention can be used for a ceramic heat accumulator, a filtering material for wastewater and waste gas treatment and an energy-saving and heat-preserving material for buildings.

Description

technical field [0001] The invention relates to a resource treatment process for building material solid waste. Background technique [0002] Construction solid waste is a variety of organic and inorganic solid waste produced during the construction, renovation, and maintenance of various buildings. It has the characteristics of many types of materials, large processing volume, and difficult processing. At present, my country lacks and does not have the process, personnel, equipment, and technical conditions for the classified demolition, classified stacking, and classified treatment of building materials. Most of the construction solid waste treatment and disposal methods in our country can only be transported to the suburbs and remote areas. Landfilling and stacking, the plants that form the construction solid waste treatment and disposal area are difficult to grow, and the harmful substances contained (harmful metal ions, germs and microorganisms) seriously pollute the gro...
