This high-speed centrifugal spray dryer machine will meet the customer's annual output of 10000 tons of polyaluminum chloride drying, and the dehydration of materials will be reduced from 43.3% to ≤4%.
Polyaluminum chloride is an important component of drinking water flocculants.
Poly aluminum chloride (Poly aluminum Chloride) also called PAC. Usually also called water purifier or coagulant, it is a water-soluble inorganic high molecular polymer between ALCL3 and AL(OH)3, and its general chemical formula is [AL2(OH)nCl6-nLm] where m represents the degree of polymerization, and n represents the degree of neutrality of the PAC product. The color is yellow or light yellow, dark brown, dark gray resinous solid. The product has strong bridging and adsorption properties. During the hydrolysis process, physical and chemical processes such as coagulation, adsorption and precipitation will occur. The fundamental difference between polyaluminum chloride and traditional inorganic coagulants is that traditional inorganic coagulants are low-molecular crystalline salts, while the structure of polyaluminum chloride is composed of polyhydric carboxyl complexes with variable shapes, and the flocculation and precipitation speed is fast, suitable for Wide range of PH value, non-corrosive to pipeline equipment, obvious water purification effect, can effectively remove color SS, COD, BOD and heavy metal ions such as arsenic and mercury in water. This product is widely used in drinking water, industrial water and sewage treatment field.
PAC polyaluminum chloride has the advantages of good spray drying stability, wide water area, fast hydrolysis speed, strong adsorption capacity, large alum flower formation, fast sedimentation, low turbidity of effluent, and good dehydration performance. In this situation, the dosage of spray-dried polyaluminum chloride is reduced, especially in the case of poor water quality. Compared with drum-dried polyaluminum chloride, the dosage of spray-dried products can be reduced by half, which not only reduces the labor intensity of workers, but also What is more important is to reduce the cost of water production for users. In addition, the use of spray drying products can ensure safety, reduce water accidents, and is very safe and reliable for residents' drinking water.
Polyaluminum Chloride adopts the most advanced production technology at present, and uses high-efficiency and high-quality raw materials to react and polymerize. Production is carried out in accordance with the requirements of the national standard GB15892-2009. Polyaluminum chloride is processed by spray drying process
