Case summary: fluorocarbon resin is a kind of thermoplastic resin containing fluorine atoms in molecular structure. It is polymerized from fluorine and carbon lock contained in fluorite ore. Dozens of fluorocarbon resins have been developed. The design of fluorocarbon special pressure spray drying tower based on many years experience is especially effective for fluorocarbon resin drying.
Fluororesin is a kind of thermoplastic resin containing fluorine atom in molecular structure. It is polymerized by fluorine element and carbon lock contained in fluorite ore. at present, dozens of fluorine resin have been developed, the main varieties are polytetrafluoroethylene (PTFE), poly (trifluoroethylene) (PCTFE), polyvinylidene fluoride (PVDF), ethylene tetrafluoroethylene copolymer (ETFE) and ethylene trifluorochloroethylene Copolymer of olefin (ECTFE), polyvinylidene fluoride (PVF), etc. Due to its non viscosity, heat resistance, chemical stability, smoothness, drug resistance, solvent resistance, water and oil resistance, wear resistance, dielectric property and other excellent properties, fluororesin is widely used in surface coating, molding products, film, building materials and many other fields.
Fluorine resin dryer:
The pressure spray drying tower is a device for drying and granulation at the same time. According to the process requirements, the pressure, flow rate and the size of spray hole can be adjusted. The spherical particles with certain size and proportion are obtained.
The pressure spray dryer has good fluidity and wettability. Commonly used pressure type spray dryer adopts parallel parallel vertical wind field, and the droplets are larger and the drying time is longer. Therefore, the shape of the dryer is mainly tower shaped, so that the fog droplets have enough residence time.
The material of tower, pipeline and separator of fluorocarbon resin pressure spray drying tower and material contact part is made by SUS304. There is an insulating layer between the inside and the shell of the tower body. The filling material is rock wool. The tower body is equipped with observation door, mirror, light source and control instrument, which is controlled and displayed by the electrical control console.
The heat source of the unit adopts steam heater, electric heater or other types, which has the advantages of convenient operation, fast start-up, compact mechanism and clean hot air. In addition, the electric control cabinet is equipped with a control and adjustment device for heat source, so that the inlet temperature can be adjusted infinitely. Our factory can provide different heating methods according to the actual needs of users.
Fluorocarbon pressure spray dryer performance characteristics:
1. It has ideal effect on the drying of non viscous and low viscous liquid materials.
2. The nozzle structure is simple, easy to use and maintain.
3. The atomization power is small and the operation cost is low.
4. The product is hollow spherical with large particle size, good solubility and fluidity.
5. It can be used for spray cooling granulation, such as paraffin wax, granular oil, chemical resin, etc.

The pressure spray drying tower is a device for drying and granulation at the same time. According to the process requirements, the pressure, flow rate and the size of spray hole can be adjusted. The spherical particles with certain size and proportion are obtained.
The working process of fluorine resin drying unit is as follows: the feed liquid is pressurized into the pressure atomizer by high-pressure pump to atomize the material liquid. The droplets are mixed with the hot air entering the drying tower through the distributor in the drying tower for rapid heat and mass transfer. The products are loose porous spherical particles with particle size less than 0.5mm. The single machine can be installed with one to dozens of nozzles, and the amount of liquid sprayed per hour can range from tens of kilograms to tens of tons. The waste gas is discharged by the exhaust fan, and the powder is collected by the powder collector under the cyclone separator. The fan outlet can also be equipped with a secondary dust removal device, with the recovery rate of 96% - 98%.
