Coal water slurry made by combining lincomycin wet bacteria slag and coal

Abstract

The invention relates to a coal water slurry combined by a lincomycin wet bacteria slag and coal which effectively settles the application of the lincomycin wet bacteria slag and prevents the pollution problem to environment. The settled technical scheme comprises the following steps: the coal water slurry is prepared by the lincomycin wet bacteria slag, a coal dust, an additive agent and water, wherein the weight ratio of the lincomycin wet bacteria slag and the coal dust is: 5-501f lincomycin wet bacteria slag, 50-951253232014f coal dust, then sum of the lincomycin wet bacteria slag and coal dust is 50-70, the additive agent is 0. 1-5and water balance by weight percentage, firstly the additive agent, water and lincomycin wet bacteria slag are mixed and stirred to a uniform mixture solution, then the coal dust is added in the mixture solution to mix uniformly and the coal water slurry with a mass concentration of 50-70 ontaining the lincomycin wet bacteria slag and the coal dust is obtained. The coal water slurry has simple component and low cost, and is easy to produce. The incomycin wet bacteria slag is fully used, not only the novel fuel source is solved and a great deal of coal is saved, but also the pollution to environment by incomycin wet bacteria slag is prevented. The coal water slurry of the invention has a huge economy and social benefit.

Description

1. Technical field [0001] The invention relates to the fuel field, in particular to a coal water slurry prepared by blending lincomycin wet fungus residue and coal. 2. Background technology [0002] Coal slurry fuel was developed in the mid-1970s under the impact of the oil crisis. Coal slurry fuel has the characteristics of less investment, easy processing, good stability and fluidity, easy loading and unloading, storage, transportation and direct atomization combustion. It can be widely used in industrial boilers, power plant boilers, and industrial kilns for oil combustion, and can also be used as gasification raw materials for synthetic ammonia, synthetic methanol, synthetic urea and other chemical fields. Coal slurry fuel technology is a clean coal technology suitable for my country's national conditions. The development and utilization of coal slurry combustion technology is of great significance to ensure the sustainable development of my country's energy and economy...

Problems solved by technology

[0009] In view of the above situation, in order to overcome the defects of the prior art, the purpose of the present invention is to provide a kind of coal-water slurry made of lincomycin wet slag and coal, which can effectively solve the utilization of lincomycin slag and prevent environmental pollution. The pollution problem caused, the technical solution for its solution is that the coal water slurry is made of lincomycin wet slag, coal powder, additives and water, wherein the weight percentage of lincomycin wet slag and coal powder It is: 5-50% of lincomycin wet fungus residue, 50-95% of coal powder, and then in weight percentage: 50-70% of lincomycin wet fungus residue and coal powder, 0.1-5% of additive , the balance is water, first mix and stir additives, water, and lincomycin wet fungus residue to form a mixed solution, then add coal powder into the mixed solution, and mix to make a mixture containing lincomycin wet fungus residue and coal powder Mass concentration is 50-70% coal water slurry, said additive is the additive that is suitable for coal water slurry, as anionic type coal water slurry additive and nonionic type coal water slurry additive, its addition can change to a certain extent The slurrying performance of coal water slurry meets the requirements of gasifier or combustion furnace. The so-called anionic coal water slurry additives include: various substituent polynaphthalene sulfonate series, lignin sulfonate, humic acid Any one of salt and sulfonated humate series, polyolefin series, carboxylate and phosphate series, acrylic acid series, non-ionic coal water slurry additives, including: polyoxyethylene series, polyoxyethylene series In any one, said pulverized coal is the pulverized coal (except peat, lignite) that is made by pulverizing coal, the addition of water in the component of the present invention can be according to the size of coal-water slurry mass concentration and coal sample It is determined by the quality and the amount of moisture in the pulverized coal, which is given by the following formula:
