Abstract
The invention discloses a powder type coal binder. Each ton of pulverized coal is mixed with the following materials of, by weight, 0.8-1.0 kg of polyvinyl alcohol, 0.3-0.4 kg of cellulose, 0.15-0.20 kg of acrylamide and 8-12 kg of soil. The powder type coal binder has the advantages that 1) by binding pulverized coal into shapes, the utilization efficiency of waste pulverized coal can be improved; 2) the purity of shaped coal can be improved, and accordingly calorific value of the coal can be improved, losses can be reduced, and coal combustion can be more sufficient; 3) smoke from coal burning can be effectively reduced and further pollution and damage to human can be reduced; 4) the shaped coal is convenient and rapid to transport; 5) the powder type coal binder is convenient to use and capable of improving the combustion time and efficiency and saving the cost.
Description
Technical field
The invention belongs to moulded coal processing technique field, and in particular to a kind of adhesive of technical powder moulded coal.
Background technology
Production moulded coal must add adhesive, and the performance of adhesive is good and bad, directly decides the quality of briquet quality,
Adhesive is the core technology of shaped coal technology；At present the species of coal briquette bond can be divided into organic and inorganic and compound three major types.Its
In, composite adhesive is combined by two or more organic and/or inorganic bonds, to make up single adhesive not
Foot, makes moulded coal reach better quality.
But, the composition of current composite adhesive varies, and the difference of its composition affects on the final mass of moulded coal
It is very big and its addition is also larger, usually 10% or so of quality of pc.The cold strength that also there is such as moulded coal is poor, ash content
High, water proofing property is poor, incomplete combustion, burning time is short, burn after there is evil mind, the problems such as exhaust smoke level is big.Therefore, how to multiple
Close adhesive to be studied to obtain higher-quality moulded coal, be the problem of the field concern.
The content of the invention
It is an object of the invention to provide a kind of pollution less, purity is high, calorific value is high, the infant industry powder of burning time length
Coal briquette bond.
The present invention is accomplished by, a kind of powder coal briquette bond, the coal dust mixing per 1 ton of component with
The material of lower weight portion：Polyvinyl alcohol 0.8-1.0kg, cellulose 0.3-0.4kg, acrylamide 0.15-0.20kg, native 8-
12kg。
Preferably, described soil is bentonite.
Preferably, described cellulose is hydroxypropyl methyl cellulose.
The present invention has advantages below：1）The coal ash of powder is carried out into adhesion-molded shape, waste-powder coal is improve
Utilization ratio；2）The purity of moulded coal is improved, and is improve the calorific value of coal, is reduced loss, and it is more abundant to burn；3）Effectively subtract
The generation of few coal smoke, reduces pollution and the injury to human body；4）Moulded coal after shaping can be transported conveniently；5）User
Just, burning time and efficiency are improve, cost has been saved.
Specific embodiment
Embodiment 1
A kind of powder coal briquette bond, the coal dust per 1 ton of component mixes the material of following weight portion：Polyvinyl alcohol 0.8kg, fiber
Plain 0.3kg, acrylamide 0.15kg, native 8kg.
Embodiment 2
A kind of powder coal briquette bond, the coal dust per 1 ton of component mixes the material of following weight portion：Polyvinyl alcohol 0.9kg, fiber
Plain 0.35kg, acrylamide 0.16kg, native 9kg.
Embodiment 3
A kind of powder coal briquette bond, the coal dust per 1 ton of component mixes the material of following weight portion：Polyvinyl alcohol 0.9kg, fiber
Plain 0.4kg, acrylamide 0.17kg, native 10kg.
Embodiment 4
A kind of powder coal briquette bond, the coal dust per 1 ton of component mixes the material of following weight portion：Polyvinyl alcohol 0.9kg, fiber
Plain 0.33kg, acrylamide 0.17kg, native 10kg.
Embodiment 5
A kind of powder coal briquette bond, the coal dust per 1 ton of component mixes the material of following weight portion：Polyvinyl alcohol 1.0kg, fiber
Plain 0.4kg, acrylamide 0.20kg, native 12kg.
After the completion of adhesive configuration, by coal dust by tape transport to mixer, the adhesive and on a small quantity of allotment is added
Water be stirred, after three minutes, the coal dust being stirred is transported into ball press with conveyer belt, round ball is pressed into by ball press
Shape, dryer is entered by round coal briquette by conveyer belt again, through the drying of a hour, treats the moisture evaporating completely inside coal briquette
Afterwards, package is packed by sack filling machine, so qualified briquette prod just completes.
