Abstract
The invention relates to a compound additive for briquettes, which comprises the following raw materials by weight: 5-15 parts of calcium lignosulphonate, 1-6 parts of sodium dihydrogen phosphate, 0-7 parts of electric lime, 5-15 parts of magnesium chloride, 0.5-5 parts of humic acidic ammonium, 5-15 parts of calcium hydrate, 2-6 parts of potassium nitrate, 0.5-3 parts of potassium permanganate, 0.2-2 parts of sodium nitrate, 0-3 parts of sodium chloride, 6-12 parts of kaoline, 3-7 parts of castor seed oil residue, 0.2-1 parts of polyvinyl alcohol and 8-12 parts of water. A preparation method thereof comprises the step of only uniformly mixing the raw materials by weight. The briquettes prepared by mixing the compound additive, coal washery sludge and middlings can be free of drying so as to lower the cost, has the smoke suppression effect of 70-90 percent and can also achieve the environmental protection requirements through detection by Shanxi Institute of Coal Chemistry, Chinese Academy of Sciences and Taiyuan environmental detection center.
Description
Technical field
The invention belongs to a kind of composite assistant, be specifically related to a kind of composite assistant that is used for moulded coal.
Background technology
The production of existing moulded coal, mostly adopt organism liquid adhesive and coal dust mixing moulding, moulding is after special drying plant is made briquette prod after drying, and the moulded coal that existing stoving process is produced, facility investment is big, will use a considerable amount of bunker coals during oven dry, and self-pollution is serious, product intensity is low, the used binding agent expense of moulded coal height, in combustion processes,, do not reach environmental protection standard during burning because the defeated and dispersed dust amount of carrying that causes in the flue gas of moulded coal is big.The shortcoming that above moulded coal exists mainly is that the composite assistant of its interpolation causes, and it is seriously restricting the development of moulded coal, and therefore, the composite assistant of improving interpolation is imperative.
Summary of the invention
Technical problem to be solved by this invention provides a kind of composite assistant that is used for moulded coal, this composite assistant and coal washing mud and wash in the moulded coal that is mixed and made into of coal can exempt from oven dry, eliminate smoke, Gu sulphur reaches environmental requirement.
Technical scheme of the present invention: a kind of composite assistant that is used for moulded coal, it is made by the raw material of following weight part: 5 parts of calcium lignin sulphonate 5-1, SODIUM PHOSPHATE, MONOBASIC 1-6 part, Calcium Carbide Ash 0-7 part, 5 parts of magnesium chloride 5-1, ammonium humate 0.5-5 part, 5 parts of calcium hydroxide 5-1, saltpetre 2-6 part, potassium permanganate 0.5-3 part, SODIUMNITRATE 0.2-2 part, sodium-chlor 0-3 part, kaolin 6-12 part, castor seeds dregs of fat 3-7 part, polyvinyl alcohol 0.2-1 part, water 8-12 part, its preparation method is: the raw material of above-mentioned weight part is mixed get final product.
The present invention compared with prior art has following beneficial effect: 1, cost is low, the moulded coal that is mixed and made into of coal need not oven dry with coal washing mud and in washing, make the low 50-60% of facility investment that moulded coal adopts stoving process than prior art, cold strength＞500N/, hot strength＞300N/, but temperature ordinary production below-20 ℃; 2, easy firing, grey melting point transport percentage of damage＜5% more than or equal to 1250 ℃, and smoke effect can reach 70-90%.With 40 parts in above-mentioned composite assistant and coal washing mud, coal is 60 parts in washing, mixing and stirring, and the moulded coal that is pressed into, through Shanxi Inst. of Coal Chemistry, Chinese Academy of Sciences's coal analysis test result such as following table:
Environment detection result is as follows through the Taiyuan City:
Sample MS-06-001: full sulphur (%) 0.30 in the coal; Pit ash 43.13;
Sample MS-06-002: full sulphur (%) 1.06 in the coal; Pit ash 26.02.
