Description
Technical Field
The invention relates to a device for preparing coal water slurry by utilizing 1-aminoanthraquinone production wastewater and a using method thereof, belonging to the field of chemical equipment.
Background
Coal water slurry CWS (coalwater slurry), also called CWM (coalwater slurry), is a solid-liquid dispersion system composed of 60-70% of coal, about 30% of water and about 1% of additives. The coal-water mixture is a thermodynamically unstable system, and is very easy to form an agglomeration structure, so that limited water is wrapped in the agglomeration structure to increase the viscosity of the system and deteriorate the fluidity. The dispersant can change the surface property of the coal particles through the adsorption on the surfaces of the coal particles, so that the water bound in the coal particles is dissociated, and the stability and rheological property of the suspension system are improved. The coal water slurry dispersing agent refers to a surfactant added into the coal water slurry. Can make coal particles stably disperse in water, and does not generate layering and precipitation for a long time. Commonly used surfactants include sulfonate ionic surfactants (e.g., lignosulfonate tea sulfonate, alkenyl sulfonate, etc.), polyoxyethylene nonionic surfactants, water-soluble high molecular polymers, and anionic surfactant and nonionic surfactant combinations. The dispersant is the key for preparing excellent water-coal-slurry. At present, the coal water slurry dispersing agent mainly comprises the following types: high condensation degree naphthalene sulfonic acid condensation compound, acrylic acid and other acrylic acid monomer copolymerization, polyolefin series, lignosulfonate, humate and sulfonated humate series, carboxylate and phosphate series and nonionic dispersant. The polycarboxylic acid series polymer additive has a flexible structure, can change the molecular weight and the molecular structure according to actual needs, and has a wide application range. In the past, the coal water slurry dispersing agent mostly adopts anionic type and nonionic type. Currently, the coal water slurry dispersants for industrial application mainly comprise naphthalene series, humic acid series, lignin series, acrylic acid series and related compound products. Although the naphthalene dispersant has low price, good dispersibility and strong viscosity reduction effect, the naphthalene dispersant is easy to generate hard precipitation by water separation. The lignosulfonate has poor performance and is generally compounded with other dispersants for use. The humic acid dispersant has the problems of high pulping viscosity and large addition amount, and other nonionic dispersants are high in efficiency, but high in price and high in pulping cost. The polycarboxylic acid dispersant has a flexible structure, can change the molecular weight and the molecular structure according to actual requirements, has a good dispersing effect on coal water slurry, but the polycarboxylic acid dispersant used at present is expensive. The applicant finds that the 1-aminoanthraquinone or DSD acid production wastewater is used for modifying an aminosulfonic acid formaldehyde condensate or a sulfonated acetone formaldehyde condensate, so that the dispersing effect of the aminosulfonic acid formaldehyde condensate or sulfonated acetone formaldehyde condensate as a coal water slurry dispersing agent can be improved. However, the applicant finds that when the product is applied to the field of coal water slurry, the adaptability of the product to coal is not ideal enough, most of the dropping in the production process of the coal water slurry dispersing agent needs manual operation or care, so that the production efficiency is low, the labor intensity is high, and meanwhile, the raw coal is not sufficiently utilized in the existing production process of the coal water slurry, so that the cost is high.
