Abstract
The present invention provides a composite adhesive for industrial briquettes. Inorganic chemical industrial raw material and organic chemical industrial raw material are adopted to form a composite multielement polymer; unique physical performance and chemical performance make produced industrial briquettes achieve the requirement of industrial application. The present invention has the advantages that the composite adhesive for industrial briquettes is suitable for bituminite, anthracite, coke dust and briquette slurry to produce industrial boiler briquettes and gasified briquettes; the composite adhesive for industrial briquettes has little equipment investment and can slightly reform an original production line for producing carbonized briquette balls for a fertilizer plant; the composite adhesive for industrial briquettes has low production cost; raw materials can be purchased in any city; each ton of briquettes is about 30 yuan; the composite adhesive for industrial briquettes high cold strength, high hot strength and high heating quantity; the thermal stability of the composite adhesive for industrial briquettes achieves 90%; the briquettes are naturally solidified or dried by residual heat.
Description
According to statistics, surplus the national Industrial Boiler 40 ten thousand, 160,000 of Industrial Stoves, wherein 70% belongs to grate firing type, be suitable for using block coal, and the production of China's fuel gas and fertilizer plant's synthetic production also all need use lump coal, but because the improving constantly of mining mechanization degree, lump coal yield descends 30% than original, can't satisfy the needs of industrial lump coal, the fragmentation between accumulating in addition, loading and unloading causes a large amount of fine coal to overstock, cause lump coal valency height, production cost enlarges.Industrially in addition use the not only utilization ratio low (having only about 60%) of coal of loosing, and flue dust, sulfurous gas is more serious to atmospheric pollution.National for this reason the rational and efficient use coal resources, develop clean coal technology and bring up to critical role, and " an industrial shaping coal exploitation " classified as national science and technology research project, there is part to economize at present, the city takes to transform measures such as boiler, the diffusing coal of taboo burning and promotes industrial shaping coal.
Moulded coal has only the requirement of satisfying long-distance transport and air storage, and has identical with lump coal or better properties just can come into the market, and could realize industrialization, commercialization.Traditional industrial shaping coal is mostly mixed lime or soil with coal dust, makes coal briquette or charing coal briquette and replaces coal cinder to use.Though developed organic and inorganic tackiness agent in recent years, and obtained certain effect, the real existing level that belongs to China's technology as CN1148083A, CN1149617A, CN1101663A, CN1106452A, CN1188141A, CN1215077A announced, but all low, poor stability because of hot strength, ash fusion point is low, production cost is high, some also need increase drying plant, costly etc. former thereby fail to obtain big area and promote.
This provides a kind of composite adhesive for industrial briquettes clearly, adopts inorganic, Organic Chemicals, forms physics and the chemical property of composite multi-component polymkeric substance with uniqueness, makes the industrial shaping coal of production reach the industrial application requirement.Its maximum characteristics are: 1, be suitable for bituminous coal, hard coal, breeze, coal slime manufacture boiler briquette and gasification briquette; 2, facility investment is few, and former fertilizer plant production charing coal briquette production line is transformed slightly and got final product; 3, production cost is low, and raw material prefectures and cities all can buy, and moulded coal per ton needs about 30 yuan; 4, hot and cold intensity, thermal value height; Thermostability reaches 90%; 5, moulded coal spontaneous curing or utilize waste heat oven dry all can.
Composite adhesive for industrial briquettes of the present invention is made up of carboxymethyl cellulose, water glass, potter's clay, calcium oxide.The per-cent of various compositions is: carboxymethyl cellulose: 8～10%, water glass: 22～25%, potter's clay: 35% calcium oxide: 15～35%, silica: 0～15%.
Composite adhesive for industrial briquettes provided by the invention adopts powder production equipment and method: earlier with various components in certain proportion meterings, adding the screw cone mixing machine mixes, by transport unit the powder that mixes is added disintegrating apparatus then, be crushed to the above back of 100 orders and pack standby.
Below in conjunction with embodiment composite adhesive for industrial briquettes application of the present invention is described further:
Embodiment 1, Industrial Boiler moulded coal: get and be crushed to＜bituminous coal of 3mm, 90 parts of coal slimes, its moisture controlled is within 6～8%, get carboxymethyl cellulose 8% again, water glass 22%, potter's clay 35%, 10 parts of the composite adhesives of calcium oxide 35% preparation, add and to mix in the coal and stir, total moisture is controlled at about 15% in the compound, compound is sent into the moulded coal of making 40mm * 37mm * 37mm in the shaper, 1.5 meters high whereabouts of wet bulb are not loose not broken, 24～38h can transport after solidifying, behind the natural air drying, cold strength reaches 60kg/, sulfur-fixing rate 30～60% steeps tens of day broken do not loose in water, is suitable for various Industrial Boilers, kiln is used.
Embodiment 2, gasification briquette: get and be crushed to＜hard coal of 3mm, 90 parts of coke powders, its moisture controlled is within 6～8%, get carboxymethyl cellulose 10% again, water glass 25%, potter's clay 35%, calcium oxide 15%, 10 parts of the composite adhesives of silica 15% preparation, add and to mix in the coal and stir, the compound total moisture is controlled at about 15%, logical the sending into of compound made 60mm * 47mm * 40mm in the shaper, the moulded coal of 56mm * 36mm * 36mm, wet bulb 1.5m does not loose not broken in high whereabouts, 24～38h can transport after solidifying, seasoning or utilize waste heat oven dry to get final product, cold strength 60kg/, hot strength 40kg/, thermostability reaches 90%.Be suitable for gas making sector applications such as fertilizer plant, producer gas plant.
