Abstract
The present invention discloses a kind of auxiliary agent of recycling treatment solid waste, counts in parts by weight, including following component：3 10 parts of burnt foam, 10 40 parts of cement, 3 10 parts of fluorite, 3 10 parts of lime stone, 3 10 parts of slag.By 30~78wt% of solid waste, surplus is auxiliary agent, and solid waste is mixed with auxiliary agent, is heated at high temperature to melting, and separation cooling obtains metal alloy and mineralising vitreum.Compared with existing auxiliary agent, slag making function, restoring function, mobility can be improved in auxiliary agent used by mineralising vitreum processing of the present invention, to improve ability and reduction that solid waste is melted ability and mineralising vitreum product to the solidification effect of heavy metal ion, the leaching for poisoning element in mineralising vitreum product is reduced, environmental improvement requirement is reached.
Description
Technical field
The invention belongs to pollution control fields, and in particular to a kind of auxiliary agent of recycling treatment solid waste.
Background technology
China generates a large amount of solid waste every year, causes serious environment and geology to endanger, and occupy a large amount of soil
Ground.Current widely applied burning disposal can not disposably solve the problems, such as innoxious.Recycling treatment solid waste mineralising glass
Glass body product technology is the novel method for carrying out harmless treatment to solid waste a kind of at present, and this technology can be by heavy metal
Organic matter, closing heavy metal are restored and destroyed, and is substantially reduced the volume of waste, especially suitable for burning the flying dust generated, containing
There is the hazardous waste of the harmful toxic matters such as heavy metal, it converts solid waste reduction to metal alloy and tool using means such as high temperature
There is the mineralising glassy state product of impalpable structure.
That there are slag making functions is poor for auxiliary agent used by the processing of existing reclamation of solid wastes mineralising vitreum, mobility is low
Problem, so that the leaching concentration of the harmful toxic matters such as heavy metal ion is not achieved environmental improvement and wants in mineralising vitreum product
It asks.
Invention content
The technical problem to be solved by the present invention is to overcome the defects that existing resourceization handles solid waste, provide a kind of money
Sourceization handles the auxiliary agent of solid waste.
In order to solve the above technical problem, the present invention provides the following technical solutions：
A kind of auxiliary agent of recycling treatment solid waste, is counted, including following component in parts by weight：
Burnt foam 3-10 parts,
10-40 parts of cement,
3-10 parts of fluorite,
3-10 parts of lime stone,
3-10 parts of slag.
The auxiliary agent is faster and better converted to metal alloy and mineralising vitreum for reclamation of solid wastes processing：It presses
30~78wt% of solid waste, surplus are auxiliary agent, and solid waste is mixed with auxiliary agent, and high temperature reduction is heated to melting, separation cooling
Obtain metal alloy and mineralising vitreum.
Further, it is heated to melting at 1200-1400 DEG C.High temperature reduction reaction occurs simultaneously.
Compared with existing auxiliary agent, auxiliary agent used by recycling treatment solid waste of the present invention can be improved slag making function, go back
The melting temperature of former function, mobility, solid waste can be down to 1100-1300 DEG C by existing 1200-1400 DEG C, and molten mass is not
It is sticky, to improve ability and reduction that solid waste is melted ability and mineralising vitreum product to heavy metal ion
Solidification effect reduces the leaching for poisoning element in mineralising vitreum product, reaches environmental improvement requirement.
