Abstract
The invention provides a method for producing wood charcoal by using furfural residue and paper-mill waste pulp, comprising the following steps of: collecting the furfural residue and the paper-mill waste pulp, mixing the furfural residue and the processed paper-mill waste pulp in weight ratio of 3:2, stirring, smashing, sieving to obtain a mixture of particles with diameters of 2-3mm, putting the mixture in a pressure system, forming blocks under pressure, putting the blocks in an environment-friendly charcoal kiln, sealing, heating to 400-550 DEG C, keeping the temperature for 45-50h, stopping heating, sealing, naturally cooling for 20-25h, unsealing, drawing out of the kiln till the kiln temperature is reduced to 50-60 DEG C, thus obtaining finished products. According to the invention, the furfural residue and the paper-mill waste pulp can be used to produce the wood charcoal; and the method is simple, convenient, practicable and capable of turning waste into wealth, treating and avoiding increasingly serious environment pollution and has the advantages that the produced wood charcoal is cheap, environment friendly, pollution-free, not explosive, low in ash content, large in calorific value and long in burning time.
Description
Technical field
The invention belongs to the environmental friendly regenerated technical field of utilizing of trade refuse, relate to a kind of method of producing charcoal with the useless slurry of furfural dregs and paper plant.
Background technology
Charcoal is an indispensable valuable cargo in the national economy.The staple of charcoal is a carbon, and ash content is very low, and about 27.21～33.49 million Jiao/kilograms of calorific value also have hydrogen, oxygen, nitrogen and a spot of other elements in addition.Charcoal belongs to the hydrophobic nature material, and ash oontent is in 6%, and hole accounts for the charcoal volume more than 7%, and proportion is generally 1.3～1.4, and thermal value depends on carbonization condition, generally about 5790 kcal/kg.The reducing power of charcoal is greater than coke.Charcoal has a large amount of micropores and transitional pore, makes it that higher specific surface area not only arranged, and after tar material is excluded in the hole good attraction performance will be arranged.
The original applications of charcoal is a fuel, it have combustion time long, calorific value is high, do not smolder, multiple advantage such as detonation, environmental protection not.Because inflammable, the anti-combustion of charcoal, ash content are few, characteristics such as sulfur-bearing not, so be a kind of fine fuel always.
Charcoal is because its unique microvoid structure and superpower adsorptive power are widely used in many aspects such as food, pharmacy, chemical industry, metallurgy, national defence, agricultural and environment protection.
Sphere of life: charcoal is optimized fuel such as barbecue, chafing dish.Machine-made carbon particularly, because it is through the high temperature refining, thus be smokeless, nontoxic, free from extraneous odour, dryness-fire star not during burning, ash content is low, and thermal value is big, and combustion time is long, more and more receives people and favors.
Industrial circle: utilize unique microvoid structure of charcoal and superpower adsorptive power.In industry with charcoal come to food, medicine, drinks, oils, water purify, noble metal reclaims or the like, adsorb, remove photoresist, eliminate the unusual smell, and the gas sweetening of environmental protection aspect, WWT etc.
Furfural dregs is the industrial residue of producing behind the furfural, and is discarded as industrial waste at present, contaminate environment, and the furfural dregs water ratio is about 45%, and it contains 70% the organic matter of having an appointment, pH value about 1.90.
Mainly contain pollutents such as a large amount of semicelluloses, xylogen, inorganic acid salt, fiber fines, mineral filler and printing ink, dyestuff in the paper waste of paper mill discharging.Xylogen, semicellulose mainly form the COD (chemical oxygen demand) and the BOD5 (biochemical oxygen demand) of waste water; The main SS (suspended substance in the water quality) that forms such as fiber fines, mineral filler; Main colourity and the COD of forming such as printing ink, dyestuff.It is higher that these pollutent concentrated expressions go out SS, the COD index of waste water.Therefore, when former water SS and COD concentration are higher, should delivering a child method processing after the one-level materialization is handled, make treat effluent finally reach the requirement of discharging standards.Waste water is after materialization, biological method are handled, and suspended substance wherein has to separate more than 90% becomes mud.Air supporting mud (deposition thickened sludge) water ratio 97%, the about 2.3～2.6t/t paper of sludge quantity; Moisture percentage in sewage sludge about 75% behind the mechanical dehydration, the about 0.3～0.4t/t paper of dewatered sludge amount; Nature dewatered sludge water ratio is higher, sludge quantity＞0.7t/t paper.The loss of slurry is inevitable in paper-making process, the harm environment.
Summary of the invention
The purpose of this invention is to provide a kind of method of producing charcoal with the useless slurry of furfural dregs and paper plant, can produce charcoal with the useless slurry of furfural dregs and paper plant, this method can turn waste into wealth; Simple and easy to do; Can administer and avoid day by day serious environmental to pollute, the charcoal of producing burns low price, environment friendly and pollution-free, detonation not, and ash content is low; Thermal value is big, and combustion time is long.
For this reason, a kind of method with furfural dregs and domestic sludge fermentation to produce biological fertilizer, it is to be made up of following technology:
(1) collect the useless slurry of furfural dregs and paper plant, with the furfural dregs airing, making its water ratio is 12～15%, and the useless slurry of paper plant adopts common pressure filter or belt filter press to dewater and isolates paper pulp, it is air-dry, and making its water ratio is 15～20%;
(2) paper plant after furfural dregs and the processing is given up slurry by weight 3: 2, mix, stirring, pulverizing is sieved, and gets diameter 2～3mm particulate compound;
(3) compound is inserted carry out pressure in the pressure system and become piece, length 6～20cm, the material piece of diameter 8～16cm, or length 6～20cm, width is the material piece of 8～16cm;
(4) will expect that piece puts in the environmental protection charcoal kiln, sealing is heated to 400～550 ℃, keeps temperature 45～50 hours, stop to heat, sealing nature cooling 20～25 hours, depressurization, during to kiln temperature drop to 50～60 ℃, kiln discharge, finished product;
(5) finished product of producing is got into quantitative packaging system through conveying belt and pack, final product.Described compound is got into compressed cylindrically in the pressure system, or rectangle material piece.Pressure in the described pressure system is 60～80 t hydraulic press pressure.Aforesaid method has been realized the object of the invention.
Advantage of the present invention is to produce charcoal with the useless slurry of furfural dregs and paper plant, can turn waste into wealth, and is simple and easy to do; Can administer and avoid day by day serious environmental to pollute, the charcoal of producing burns low price, environment friendly and pollution-free, detonation not, and ash content is low; Thermal value is big, and combustion time is long.According to the charcoal product that test is produced with the inventive method, ash content is very low, about 24.22～30.01 million Jiao/kilograms of calorific value, and ash oontent is in 8%, and hole accounts for the charcoal volume more than 7%, and proportion is generally 1.4～1.5, not the favorable substitutes of charcoal still; And make the waste product of contaminate environment, and filling and part will arrive utilization, environment protecting is good.Owing in the preparation process of the present invention, handle through the high temperature non-oxidation, make the objectionable impurities in the useless slurry of furfural dregs and paper plant obtain pyroprocessing, there is not pollution problem, do not pollute the environment.
