Description
Technical field
The present invention relates to industrial shaping coal and manufacture field, particularly relate to a kind of Low Temperature Thermal junction type coal and production technology thereof.
Background technology
Moulded coal production technology has more than 100 year so far from invention, but does not has significant progress in terms of production technology, tradition
The made product of moulded coal production technology be merely capable of meeting civilian needs, and need to clean fuel in a large number and substitute tradition combustion
The industrial circle of material, the clean moulded coal not the most being suitable for can use, the reason product that mainly tradition briquetting process is produced
Product all cannot substitute conventional coke or anthracite block coal in terms of calorific intensity, heat stability and water resistance.Existing technology is
Being sticked together by coal with the mode binding agent of physical bond, being shunk by binding agent increases coal briquette intensity, and this has certain office
Sex-limited.
Summary of the invention
In place of it is an object of the invention to avoid the deficiencies in the prior art, it is provided that a kind of Low Temperature Thermal junction type coal and production work thereof
Skill, thus in place of effectively solving the deficiencies in the prior art.
For achieving the above object, the technical scheme that the present invention takes is: a kind of Low Temperature Thermal junction type coal production technology, it is concrete
Comprise the steps:
Step one: with the mixture of metallurgical coke, semi-coke powder or metallurgical coke and semi-coke powder as raw material；
Step 2: the raw material configured is carried out mixing broken；
Step 3: add binding agent and hardening agent in the raw material after broken, and obtain after stirring at normal temperatures mixed
Compound；
Step 4: kneading, utilizes kneading machine that the mixture in step 3 is carried out kneading；
Step 5: cold moudling, carries out cold moudling following with shaped device to mixture at 100 degrees Celsius；
Step 6: low temperature accumulation of heat, sends into the mixture after molding in accumulation of heat stove, and accumulation of heat furnace temperature controls 180～360
At DEG C, isothermal holding forms moulded coal finished product in 2-2.5 hour.
In low temperature accumulation of heat, metallurgical coke and semi-coke powder are polymerized with binding agent and hardening agent, contract and react, and molecule is tied
Structure changes, and forms the skeleton of moulded coal, thus improves calorific intensity and the heat stability of moulded coal.Low temperature accumulation of heat of the present invention is raw
Produce briquetting process discharge of poisonous waste few, relative to existing technologies, more environmentally-friendly.
Further, described binding agent is coalite tar, the 3-of the most described raw material of proportioning of described binding agent
10%.
Further, the 5% of the most described raw material of the proportioning of described binding agent.
Further, described hardening agent is petroleum residual oil, the 3-of the most described raw material of proportioning of described hardening agent
10%.
Further, the 5% of the most described raw material of the proportioning of described hardening agent.
A kind of Low Temperature Thermal junction type coal obtained by above-mentioned production technology.
Further, described moulded coal is casting molded coal, gas-making type coal, smelting moulded coal and coal briquette for civillan use.
The technique scheme of the present invention has the advantages that the binding agent in the present invention and hardening agent, necessarily
At a temperature of with raw material generation chemical reaction, thus effectively raise calorific intensity and the heat stability of moulded coal；Provide and do not use
Binding coal produces the new technology of industrial shaping coal with anthracite, thus reaches low energy environment protecting；Change industrial shaping coal
Can only high temperature cabonization and can not the traditional handicraft of low temperature accumulation of heat；The industrial clean moulded coal that the present invention produces, alternative conventional burnt
Charcoal and high-quality anthracite are for industry, simultaneously or excellent domestic clean fuel.
