Abstract
In the invention, coke powder and a bonding agent containing coking coal with strong bonding property are used as raw materials for processing environment-friendly formed coke. The dosage of the coke powder and the dosage of the coking coal respectively account for 80-95% and 5-20% of the total mass of the formed coke. The bonding index of the coking coal is greater than 85%. The bonding agent can contain special modifying agents, polyvinyl alcohol polymers and composite starch. The coke powder and the bonding agent can be formed by cold pressing after being evenly mixed. A wet billet can be used after being baked or aired and can also be used after being carbonized. The environment-friendly formed coke can be used for replacing coke in the industries of casting, metallurgy and the like. The invention solves the problem of environment pollution in the processing procedure of the formed coke, lowers the cost, and has very high popularization and application values.
Description
The present invention relates to a kind of working method of environmental protection formed coke.Be suitable for burnt foam and binding agent are processed into the environmental protection formed coke.
Existing formed coke working method is: with evenly back extrusion forming of burnt foam and pitch, humate dry mixing, wet-mixing, carry out charing again.Existing formed coke manufacturer all adopts this principle and technical process.This working method is because the binding agent that adopts is pitch, humate, and environmental pollution is serious, and cost is high, has influenced the development of formed coke industry.
The objective of the invention is to provide a kind of working method of environmental protection formed coke, adopt the binding agent processing formed coke of the coking coal that contains strong cohesive property, solve environmental pollution, reduce cost, promote the development of formed coke industry.
The present invention is achieved in that after burnt foam and the binding agent dry mixing, wet-mixing that contain the coking coal of strong cohesive property evenly, and coldmoulding is dried or dried and gets final product, and also can become qualified formed coke product after charing.Can add special modified dose, polyvinyl alcohol polymer and composite starch in the binding agent.
The present invention need not to add pitch, humate owing to contain the coking coal of strong cohesive property in the binding agent, has solved environmental pollution, reduces cost, and helps the development of formed coke industry.
Prescription of the present invention is provided by following examples.
Technical process of the present invention is provided by following examples.
Burnt foam → fragmentation → adding contains the binding agent → dry mixing → wet-mixing → coldmoulding → charing of coking coal
Above-mentioned finished product promptly becomes qualified environmental protection formed coke through cooling, check.
Adopt the environmental protection formed coke of above-mentioned working method processing can offer producers' uses such as casting, metallurgy.
