Abstract

The invention relates to a forming method of semicoke powder and quicklime powder. The forming method includes following steps: taking semicoke powder and quicklime powder; adding a binder; mixing well; heating; pressing for forming. The forming method is simple to operate, and powder screen underflow of semicoke blocks and quicklime blocks are adopted as main raw materials, so that resources are saved and environment is protected. By using the method, water does not need to be added into the raw materials, and prepared pellets do not need to be dried, so that energy consumption is lowered and cost is saved. The raw materials used in the method are below 1 mm in size and do not need to be further ground, and the forming method is low in requirements on raw material size and suitable for large-scale industrial production.

Description

A kind of semicoke powder and the forming method of quick lime powder
Technical field
The present invention relates to briquetting technical field, be specifically related to a kind of semicoke powder and quick lime The forming method of powder.
Background technology
At present, due to a large amount of block coke and the exploitation of lump lime and utilization, cause a large amount of Powdered coke and the generation of quick lime, serious environment pollution, and bring further resource wave The problem taken.Therefore, the most effectively utilize powdered coke and quick lime to become and need asking of solution badly Topic.
Up to now, there is multiple carbide raw materials for metallurgy forming method and be applicable to carbide smelting The binder formula of material powder molding, these methods need to add a certain amount of moisture or extra Binding agent prepare carbide raw materials for metallurgy as additive, the existence of moisture makes carbide smelt Journey power consumption increases, and binding agent makes preparation cost increase.
Summary of the invention
It is an object of the invention to solve problems of the prior art, main employing coal blending Thinking solves the key technology that calcium carbide powder is body formed, and the binding agent both having reduced carbide molding becomes This, decrease again the pollution to environment, and the binding agent used has well under the high temperature conditions Adhesive property, high-temperature calcination can make coal apoplexy due to endogenous wind used by binding agent organic adhesive composition melt Melting spilling, it has good high temperature bond performance to coal dust.
Specifically, the invention provides a kind of semicoke powder and the molding side of quick lime powder Method, described method comprises the steps: preparing quick lime powder and semicoke powder, adds binding agent Rear mix homogeneously, heat treated, compressing,.
The particle diameter of semicoke powder of the present invention and quick lime powder is all at below 1mm.Wherein, The content of ashes of described semicoke powder below 20%, the calcium oxide content of described quick lime powder More than 80%.The mass ratio of described quick lime powder and semicoke powder is preferably 1.3~1.5:1.
The particle diameter of described binding agent is in below 1mm, the one in rich coal, brown coal, coking coal Or several mixture.
The composition of described binding agent is carried out preferably by the present invention, to improve the viscous of binding agent further Knot effect.Specifically, by percentage to the quality, described binding agent comprises brown coal 30%~70%, Coking coal 30%~70%, sum of the two is 100%;Or, comprise brown coal 40%~60%, rich coal 40%~60%, sum of the two is 100%;Or, comprise coking coal 30%~60%, rich coal 20%~40%, Brown coal 20%~50%, three's sum is 100%.
In order to improve molding effect, the addition of described binding agent accounts for quick lime powder and semi-coke powder The 3~8% of the two gross mass of end.
The water content of semicoke powder of the present invention, coking coal, rich coal and brown coal all below 5%, It is preferably less than 3%.
In described method, the temperature of heat treated is 100~200 DEG C, and the time is 1~2 hour.Institute Stating compressing pressure is 10~15MPa.
The present invention protects the product using described method to prepare molding further.
The semicoke powder of present invention offer and the preparation method of quick lime powder compacting, have following Advantage: this preparation method process is simple, the powder siftage using half coke button and caustic lime block is Primary raw material, economizes on resources, and protects environment;The raw material that this preparation method uses need not add Moisture, the pelletizing of preparation, without drying, reduces energy consumption again, cost-effective;This preparation method institute With raw materials size at below 1mm, raw material is without further levigate process, to raw materials size requirement Low, be suitable to large-scale industrial production.
