solution innovation
The polyethylene special drying bed designed by our company adopts a special structural design, effectively avoiding the problem of material bonding; Fluidized bed design has different air distribution structures, with segmented control of drying temperature and air volume, which plays a role in energy conservation and consumption reduction while ensuring product quality.

Innovative technology
Wet materials enter the internal heating fluidized bed through the feeding device and form fluidization in the built-in heat exchanger area under the action of hot air. Hot water is supplied to the heat exchanger, and most of the heat required for material dehydration is provided by the heat exchanger. The moisture in the material evaporates and is carried away by the drying medium. Under the action of the drying medium, the material is discharged through the discharge port after drying and enters the next process. The dry exhaust gas carrying moisture and a small amount of dust enters the cyclone dust collector and bag filter device, and the dust is recovered. The exhaust gas is finally discharged by the induced draft fan.

Features of the Solution
1. The fluidized bed adopts a special design to effectively avoid material adhesion, and a three-layer leak proof material air distribution plate is specially designed;
2. The fluidization speed is low, and the bed design adopts an enlarged structure to reduce the concentration of tail gas entrainment;
3. The air volume and temperature of each air chamber in the fluidized bed are automatically controlled separately;
4. High heat utilization rate, the main heat required for drying is provided by the built-in heat exchanger, and the thermal efficiency can reach 90%,;
5. Single machine processing capacity is large, the system occupies a small area, and saves investment.

Implementation of the plan
