The invention discloses an adhesive, which is prepared by the following raw materials in weight ratio: 10 portions to 15 portions of asphalt powder, 10 portions to 16 portions of coal tar, 14 portions to 17 portions of tar residue, 0.1 portion of MF4, 0.1 portion of NO, 1.2 portions to 2.5 portions corrosion sodium, 0.3 portion of dodecyl benzene sulfonate, 0.5 portion of polyethylene amide, 1 portion to 1.5 portions of carboxy alkyl cellulose, 2 portions of sodium hydroxide and 1 portion of dextrin. The adhesive solves the problem of difficult molding of coke powder. The formed coke produced by the adhesive, after being dried, has coal strength of 70 kilograms to 90 kilograms per ball, does not disperse at high temperature of 1,300 DEG C, has less fixed carbon reduction amount, does not contain chemical components such as magnesium, phosphorus, aluminum, iron, and the like in additives, and has good chemical activity. The formed coke produced can be applicable to the industries such as metallurgy, chemical fertilizer, calcium carbide, and the like for replacing part of the coke.
Description
Technical field
The present invention relates to a kind of production formed coke, metallurgical coke or gasification formed coke binding agent.
Background technology
As everyone knows, current China coke price goes up to more than 1000 yuan, and some areas are especially up to 1500 yuan/ton.And the coke powder of the annual coke fragmentation of China is more than 5,000 ten thousand tons, and a large amount of coke powders can only be made low-grade fuel and handle, and price has only about 150 yuan.
Coke is the important raw and processed materials of metallurgy, machinery, chemical industry, building materials industry.The raw material of producing coke is the high-quality coking coal.Formed coke is a raw material with coke or the undersized granulated slag of coal then, produces the metallurgical coke or the foundry coke that meet national standard.Expanded the application of feed coal.Especially broken (smokelessly) coal, the broken coke less than 3mm is the raw material of making formed coke, reduced cost.Formed coke per ton can be saved coke fund 300-500 unit.Build the industrial production line of a year handling 40,000 tons of coke powders, armamentarium is invested about 1,300,000 yuan.Found the factory then, just can make a profit more than 500 ten thousand yuan then.So, utilize coke powder production to be suitable for the formed coke that industry instead of part coke such as metallurgy, chemical industry chemical fertilizer, calcium carbide are used, be that China's existing market potentiality are big, good in economic efficiency investment project.
But, in the formed coke production process, exist the problem of the extremely difficult moulding of coke powder, thereby produce with binding agent most important.
Summary of the invention
The technical issues that need to address of the present invention just are to overcome the problem of the extremely difficult moulding of coke powder that exists in the existing formed coke production process, a kind of binding agent is provided, it has solved the problem of the extremely difficult moulding of coke powder, utilize binding agent of the present invention can go out the product formed coke, 70 kilograms of-90 kilograms/single balls of dry back cold strength, not powder does not loose when 1300 ℃ of high temperature, fixed carbon reduction amount is few, do not contain Chemical Composition such as magnesium, phosphorus, aluminium, iron in the additive, chemically reactive is good, and the formed coke of production can be suitable for industry instead of part coke such as metallurgy, chemical industry chemical fertilizer, calcium carbide and use.
For addressing the above problem, the present invention adopts following technical scheme:
A kind of binding agent of the present invention, described binding agent is prepared from by following raw materials in weight portion:
Asphalt powder 10-15 part; Coal tar 10-16 part; Coke tar refuse 14-17 part; 0.1 part of MF4; 0.1 part of NO; Corrosive acid sodium 1.2-2.5 part; 0.3 part of Sodium dodecylbenzene sulfonate; 0.5 part of polyvinyl lactam; The first class that contracts Mierocrystalline cellulose 1-1.5 part; 2 parts in sodium hydroxide; 1 part in dextrin.
When being used to make coking coal, the raw material of binding agent of the present invention also comprises following parts by weight of component:
Bentonite 1-2 part; Aluminium sesquioxide 1-3 part; Lime carbonate 0.5-2 part.
Binding agent of the present invention has solved the problem of the extremely difficult moulding of coke powder, utilize binding agent of the present invention can produce formed coke, moulded coal etc., 70 kilograms of-90 kilograms/single balls of cold strength behind the formed coke product drying, not powder does not loose when 1300 ℃ of high temperature, fixed carbon reduction amount is few, do not contain Chemical Composition such as magnesium, phosphorus, aluminium, iron in the additive, chemically reactive is good.Can be suitable for industry instead of part coke such as metallurgy, chemical industry chemical fertilizer, calcium carbide uses.Use the collocation of coke enterprise to use by domestic ironmaking, casting, chemical fertilizer gas-making etc., all reached good result.While also provides practicable method for the moulding and the granulation of multiple diffusing shape powders such as smelting, chemical enterprise such as manganese ore powder, chromite ore fine, iron content dirt material.The formed coke that utilizes formed coke tackiness agent of the present invention to produce can guarantee the thermostability of formed coke, and the fixed carbon of the formed coke that do not descend again can play tangible energy-saving and emission-reduction, increase the effect of benefit.
Advantage of the present invention has: 1, easy to use: the big coke powder of water content be need not oven dry, directly in proportion coke powder, binding agent are mixed promptly plasticly, one ton of binding agent can be produced 20 tons of coke powder pelletizings; 2, excellent performance: once shaped, ratio of briquetting is up to 95-98%, do not loose in 2 meters high whereabouts of wet bulb, seasoning or oven dry all can, 100 kilograms/ball of dry back intensity, high temperature resistant 1000 ℃ of not powder that do not loose, do not contain Chemical Composition such as magnesium, phosphorus, aluminium, iron in the additive, chemically reactive is good, and fixed carbon reduction amount is little; 3, of many uses: as to utilize coke, refinery coke, blue carbon residual powder to be processed into pelletizing and to be suitable for small blast furnace ironmaking, advantages such as industry instead of part coke application such as furnace refractory, chemical industry coal gas raw material, calcium carbide raw materials for production.
