Overview of Polymer Drying Machine Equipment
The molecules of high molecular weight compounds (also known as polymers) are much larger than those of low molecular weight organic compounds. The relative molecular weight of general organic compounds does not exceed 1000, while the relative molecular weight of polymer compounds can reach 1.04-1.06 million. Due to the high relative molecular weight of polymer compounds, there are significant differences in physical, chemical, and mechanical properties compared to low molecular weight compounds. The large number of high molecular weight compounds used as materials in the world today are made from low molecular weight organic compounds starting from coal, oil, natural gas, etc., and then polymerized to produce them. These low molecular weight compounds are called "monomers", and the high molecular weight compounds formed by their polymerization reactions are also called high polymers. Aggregation reactions are usually divided into two categories: addition polymerization and condensation polymerization, abbreviated as addition polymerization and condensation polymerization.
GPG series macromolecule compound spray dryer, the tower body is polished with stainless steel, and the materials do not stick to the wall. The tail of the tower adopts a unique structure and is equipped with a direct current cyclone separation device. The method of increasing the speed of discharge is used to achieve a discharge rate of over 95% at the bottom of the dryer, and the total yield reaches 99%. The device adopts cyclone separator, wet dust collector or bag pulse dust collector. Perform secondary capture to ensure that the exhaust emissions meet national standards. Hollow spherical particle products can be continuously produced, and the particle size and moisture content of the products can be adjusted and controlled within a certain range.
Working principle of polymer dryer
Polymer drying machine is a device that can simultaneously complete drying and granulation. According to the process requirements, the pressure, flow rate, and nozzle size of the material liquid pump can be adjusted to obtain the required spherical particles in a certain size ratio.
Working process: The material liquid is input under high pressure through a diaphragm pump, and a pressure atomizer is used to spray mist droplets, which are evenly mixed with hot air for heat and mass exchange, causing the moisture in the material to quickly vaporize and evaporate. Most of the powder particles are collected from the bottom discharge port of the tower, and the exhaust gas and its tiny powder are separated by the cyclone separator. The exhaust gas is discharged by the exhaust fan, and the powder is collected by the pollination tube located at the lower end of the cyclone separator. The fan outlet can also be equipped with a secondary dust removal device, and the material recovery rate is above 95-98%. The materials of the tower body, pipeline, and separator in contact with the material are all made of SUS304. There is sufficient insulation layer between the interior of the tower and the outer shell, and the filling material is ultra-fine glass wool. The tower is equipped with observation doors, mirrors, light sources, and control instruments, which are controlled and displayed by an electrical control console. The heat source device adopts steam heating or electric heater, which has the advantages of easy operation, fast start-up, compact structure, and clean hot air. In addition, there is a control and adjustment device for the electric heater installed in the electrical control cabinet, which enables stepless adjustment of the inlet temperature.
