Description
Technical field
The present invention relates to briquette binder technical field, in particular to it is a kind of based on refreshing mansion semicoke production of shaped coal binder and
Moulded coal preparation method.
Background technique
Semicoke is the solid carbonaceous product that the high volatile coal of no cohesiveness or weak stickiness is obtained in middle low temperature pyrogenation.Semicoke
Have the characteristics that fixed carbon is high, ash content is low, sulphur is low, be rare clean fuel, but half char strength is low, is producing and is transporting
A large amount of broken foam can be generated during defeated, wherein semicoke foam of the granularity less than 6mm accounts for 10%~15% of yield or more.Refreshing mansion
Area's semicoke yield in 2017 is 35,000,000 tons, wherein about 350~5,250,000 tons of semicoke foam.Since the utilization of semicoke foam fails to have
Effect exploitation, and it is difficult to storage and transportation, price is low, seriously affects the sustainable development and whole economic efficiency of semicoke industry.Therefore, how
Upgrading processing is carried out to semicoke foam, new application approach is developed, is the key that current China's semicoke clean conversion and comprehensive utilization
One of problem.
The one kind of moulded coal as clean coal technology has small investment, quick, not only energy saving, reduce environmental pollution, but also
The comprehensive utilization of resource can be achieved.Moulded coal mainly mixes semicoke foam and binder according to a certain percentage, by being press-formed,
Drying and processing can be prepared into the moulded coal with fixed profile size.Binder is key technology in moulded coal manufacturing process, and
It restricts development of briquette and obtains bottleneck.With the development of shaped coal technology, hundreds of binders are studied in countries in the world.It is high
Acting type caking agent of coal should usually have following condition: (1) cementitiousness strong, good fluidity, easily spread in coal particle surface, be distributed it is equal
It is even；(2) binder does not increase ash in moulded coal and does not reduce calorific value；(3) preparation process is simple；(4) source it is wide, it is inexpensive,
It is without secondary pollution.
According to the chemical property of binder, inorganic binder, organic binder, compound binding agent can be divided into.
Inorganic binder such as waterglass, clay, lime, kaolin, bentonite, cement, clay, gypsum and common salt
Etc. all kinds of inorganic salts etc..This kind of binder is cheap, have certain adhesion strength, and some ingredients included can also and coal
Middle sulphur reacts, and plays sulfur fixation, is usually indispensable component part in compound binding agent.But it makes moulded coal
Calorific value reduces, moisture-proof, poor waterproof properties, and increases ash.
Organic binder such as tar asphalt, polyvinyl alcohol, phenolic resin, cornstarch, humic acid etc..This kind of binder
General adhesive property is preferable, and residual ash is few after burning, itself can partly or entirely burn, and has certain calorific value, but most
The hot property of organic binder is poor.
Summary of the invention
The purpose of the present invention is to provide one kind based on refreshing mansion semicoke production of shaped coal binder and moulded coal preparation method, with solution
The certainly above problem.
To achieve the above object, the invention adopts the following technical scheme:
One kind is based on refreshing mansion semicoke production of shaped coal binder, the raw material including following weight percent: pre-gelatinized starch
14%~21%, modified cellulose 3%~4%, sodium bentonite 75%~83%；Above-mentioned three is mixed to form binder.
Further, a kind of moulded coal preparation method based on refreshing mansion semicoke production of shaped coal binder, comprising the following steps:
Step 1, semicoke foam is processed into the semi-coke powder that granularity is less than 3mm；
Step 2, above-mentioned binder is mixed with semi-coke powder, water is added, is put into blender and stirs evenly；
Step 3, the above mixed material is pressed into cylindrical briquette on hydraulic jack press machine；
Step 4, it by the above briquette in 140 DEG C~150 DEG C drying 2h, or spontaneously dries under room temperature ventilation and obtains
State moulded coal.
Further, the quality for adding water of moulded coal accounts for the 20%~22% of semi-coke powder quality in step 2.
Further, the briquetting pressure of press machine is 20MPa~30MPa in step 3, and briquette size is 35mm × Φ
60mm。
Further, binder accounts for the 6% of semicoke additive amount, and the semicoke water content after mixing briquette binder is 20%~
22%.
Compared with prior art, the present invention has following technical effect:
1, formula of the invention is simple, and raw materials for production are easily obtained, and production cost is low, and manufacturing process is simple；
It 2, will not be to worker's body in moulded coal production process in binder of the present invention without strong acid and strong base substance or harmful substance
Generate injury；
3, the pre-gelatinized starch in the present invention and modified cellulose play cementation；
4, the sodium bentonite in the present invention plays the role of enhancing moulded coal mechanical strength and calorific intensity.
5, the present invention is using the semi coke briquette forming after this binder, and adhesive property is good, and index much meets country
Coal briquette for civillan use standard (GB34170-2017), horizontal cold pressing strength > 1000N, vertical cold pressing strength > 600N, calorific value are
27.53MJ/Kg
