Special flash dryer for polyaluminum sulfate
Polyaluminum sulfate is a composite polymer with large molecular structure and strong adsorption capacity. It is widely used in purification treatment, and its water purification effect is better than all traditional inorganic water purification agents. White polyaluminum chloride (PACl) is a kind of white or milk white powdered powder which is made of aluminum hydroxide powder and high purity hydrochloric acid by flash drying process.polyaluminum sulfate is a composite polymer with large molecular structure and strong adsorption capacity.

Advantages of polyaluminum sulfate flash dryer are as follows:
flash dryer is a kind of air flow drying equipment system with no torsion damage installation. It is a combination of fluidization, swirl, spouting, destruction and grading. It is a combination of fluidization technology, swirl technology, spouting technology and the technology of heat transmission. It is used to dry the moisture outside the material. The wet material is separated by the drying air duct of flash drying equipment and enters into the heated air flow, and the drying takes place in seconds. Flash dryer equipment has not been used in many industrial areas, including food, chemical, mineral and polymer. The combination of materials is also very common, including powder, bulk, granular, thin sheet, paste, gel and paste, etc. (reverse mixing of dry and wet materials is necessary when dealing with slurry, paste or viscous materials). Flash drying equipment is one of the common drying equipment in the growing and fast use area. In China, flash dryer is also called cyclone dryer and rotary quick dryer. As a typical fluidized drying equipment, flash drying equipment not only realizes the continuous operation of dynamic drying, but also overcomes the errors and fallacies of low efficiency of static drying, high labor intensity, pollution and serious waste, so that the chemical products in the drying unit can achieve the perfect unity of efficiency, quantity, efficiency and so on.
the technical advantages and specific application of flash dryer for polyaluminum sulfate. The slave body of flash drying equipment is a cylindrical drying chamber, which is composed of destruction fluidization section at the bottom, external drying section and top grading section. It can complete the operation of material destruction, drying and grading at the same time. In addition, there are no heater, feeder, mixing and breaking system, classifier, drying pipe, cyclone separator, bag filter and fan. After being heated, installed and heated, the natural air enters the mixing crushing drying chamber from the bottom of the dryer at the appropriate injection speed through the air inlet of the flash drying equipment, and spirally rises. At the same time, the materials are sent into the tower by the screw feeder, and the hot air is taken for filling and heat exchange, which has strong shearing, blowing and twisting effects on the materials, so that the materials meet with centrifugation, shearing, collision, etc The heat transfer is enhanced by friction. At the bottom of flash drying equipment, the larger and wetter particles are mechanically broken under the action of agitator. The particles with lower moisture content and smaller particle size are entrained by airflow and further dried and refined in the rising process. The finished products dried by flash dryer manufacturer are discharged through cyclone separator, and dust containing tail gas is discharged by pulse bag filter after dust collection Out of breath.
