Abstract
A process for producing industrial shaped coke includes such steps as breaking high-quality coal into particles with granularity less than 2mm, cold pressing with special press and water as adhesive to obtain solid brequettes, loading in kiln and conventional dry distillation. It features low cost, less energy consumption, high yield rate up to 95%, high quality and low content of volatile component.
Description
The invention belongs to a kind of formed coke production technique.
In known technology, the manufacture formed coke generally adopts coal tar or tar-bitumen to be hot pressed into moulded coal as caking agent, and the destructive distillation of shove charge secluding air forms then, and its product strength is little, and qualification rate is low, only has about 70%; The required facility of hot press forming technology is many, and power consumption is high, and production cost is big; Coal tar and tar-bitumen are made caking agent not only cost investment are big, and the formed coke volatile matter height of being produced.
Purpose task of the present invention is to improve above-mentioned formed coke production technique, reduces production costs, and reduces the volatile matter of formed coke, improves the formed coke quality.
The above-mentioned purpose task is to realize like this, at first, fine coal powder is broken into the coal dust of granularity less than 2mm, use water as caking agent, coal and water ratio (weight ratio) are 100: 8～10, are cold-pressed into solid square formula, rectangular parallelepiped formula, square column formula, square brick formula or six prismatic formula moulded coals with special pressure machinery again, and the pressure that the moulded coal after the moulding can bear is more than the 60kg, last shove charge, the destructive distillation of technology secluding air forms routinely.
Now describe the present invention in conjunction with the embodiments in detail, select cleaned coal for use, be crushed into the coal dust of 1.8mm granularity, moisture content in the coal dust is 9%, be cold-pressed into the solid moulded coal of 180 * 180 * 180mm specification again with pressing machine, this moulded coal must be able to bear the above pressure of 60kg, at last with the destructive distillation of moulded coal shove charge secluding air.Will lay the cleaned coal of one deck 20cm at the bottom of the moulded coal shove charge forehearth, and closely knit, leveling, separate with the wrapping paper of 500g between each moulded coal, the top layer of moulded coal will cover the thick middle coal of 10cm after the shove charge.
Advantage of the present invention is: cost of investment is low, and power consumption is few, and finished product rate height can be brought up to more than 95%; Product Intensity is big, and quality is good, has overcome to adopt tar asphalt or coal tar to do the high difficult problem of volatile matter due to the bonding agent, and has produced Bigger economic benefit.
Claims (4)
1, a kind of technology of manufacture formed coke, be to select for use cleaned coal after the pulverizing to add caking agent to be pressed into moulded coal, shove charge secluding air destructive distillation then the invention is characterized in fine coal powder is broken into the coal dust of granularity less than 2mm, use water as caking agent, be cold-pressed into solid moulded coal with special pressure machinery again.
2,, it is characterized in that the ratio (weight ratio) of above-mentioned fine coal and water is 100: 8～10 according to the described technology of claim 1.
3,, it is characterized in that the pressure that above-mentioned moulded coal bears is more than the 60kg according to claim 1 or 2 described technologies.
4,, it is characterized in that above-mentioned moulded coal is square formula, rectangular parallelepiped formula, square column formula, square brick formula or six prismatic formulas according to the described technology of claim 3.
