Abstract
The present invention mainly relates to fuel which uses coal as main combustion ingredients. The present invention is characterized in that coal, coal slack and plant fibre are pulverized into granules of less than 5mm; the coal, the coal slack and the plant fibre are uniformly mixed; according to the ratio that the coal is from 30 to 70%, the coal slack is from 10 to 30%, the plant fibre is from 10 to 40% and paper making black liquor is from 5 to 15%, an obtained mixture is stirred and spirally extruded to be formed in a rolling mode or a punching mode. The present invention utilizes a large quantity of industrial waste slag, waste liquor, plant straw, etc., and the present invention has the advantages of low cost, high heat value, easy combustion and long combustion time. Sulphur in the coal and the coal slack can be solidified, the discharged smoke dust can be greatly reduced, and the present invention has good social benefits, environmental protection benefits and economic benefits.
Description
The invention belongs to fuel, relating generally to coal is the fuel of main combusting component.
The various moulded coals of prior art, though utilization in various degree waste residue, waste liquid, play the effect of certain solid sulphur, slagging-off, reduction pollution, but owing to be subjected to the restriction of common forming technique, the vegetative fiber that adds is less in moulded coal, and need add a large amount of tackiness agents, stability during with the increase briquette molding, thereby cost is higher, calorific value is low, nonflammable, easily broken during transportation.
The purpose of this invention is to provide a kind ofly utilize waste material, cost is low, calorific value is high, easy firing, reduces environmental pollution, degree of compactness height, the environment-protecting energy-saving type briquette of being convenient to transport.
The invention is characterized in that coal, coal gangue and vegetable fibre are crushed to the following particle of 5mm earlier, mix, then in the ratio of coal 30～70%, coal gangue 10～30%, vegetable fibre 10～40%, black liquid 5～15%, stir, roll extrusion or impact briquetting after screw extrusion again.
Coal, coal gangue and vegetable fibre preferably are crushed to the following particle of 2mm earlier, mix, in the ratio of coal 40～70%, coal gangue 15～30%, vegetable fibre 5～30%, add black liquid 5～10% then, stirring, roll extrusion or impact briquetting after screw extrusion again.Add in the above-mentioned batching and account for the calcium hydroxide of gross weight 0.5～3% as sulphur-fixing agent.
High-efficiency environment protection energy-saving type coal of the present invention has utilized a large amount of industrial or agricultural waste residues, waste liquid, and plant straw etc., by with coal by a certain percentage behind the mixing moulding, cost is low, calorific value is high, easy firing, and combustion time is long, can solidified coal and coal gangue in sulphur, significantly reduce SO
2And soot emissions.Because of moulded coal of the present invention adopts unique post forming technology, make moulded coal density height, physical strength is big, is difficult for fragmentation, is convenient to transportation.Because coal gangue has good heat storage capacity, is easy to keep fire box temperature, can play combustion-supporting effect.Vegetable fibre calorific value height such as wood chip, branch, plant straw, shell are used for remedying the low deficiency of coal gangue calorific value, can not make the calorific value of moulded coal produce bigger variation.At aspects such as utilizing refuse, reduction pollution good social benefit, environmental benefit and economic benefit are arranged.
Embodiment 1:
Being crushed to 5mm following coal dust, coal gangue, wood chip, in the ratio of 30-35%, 30-40%, 10-20%,
Mix, add the black liquid of 10%-15% then, 2～3% calcium hydroxides stir as sulphur-fixing agent, and the material that stirs is sent in the screw extruding briquetting machine, and are closely knit through pushing, last impact briquetting.
Embodiment 2:
Being crushed to 2mm following coal dust, coal gangue, wood chip, ratio in 50-70%, 10-20%, 5-10%, mix, add the black liquid of 5%-8% then, 0.5～2% calcium hydroxide stirs as sulphur-fixing agent, the material that stirs is sent in the screw extruding briquetting machine, closely knit through pushing, last roll forming.
Embodiment 3:
Being crushed to 1mm following coal dust, coal gangue, wood chip, ratio in 35-50%, 20-30%, 20-40%, mix, add the black liquid of 8%-10% then, 0.5～2% calcium hydroxide stirs as sulphur-fixing agent, and adds paraffin or other ignition dope, and the material that stirs is sent in the screw extruding briquetting machine, closely knit through pushing, last roll forming.
Claims (3)
