This spray dryer consists of seven systems, namely feeding system, atomization system, drying tower, material recovery system, heating system, piping system and control system.
1. The feeding system consists of peristaltic pump peristaltic tubes.
2. The atomization system adopts centrifugal atomizer. The pump sends the material and liquid into the atomizer, and the high-speed airflow ejected from the annular gap of the nozzle atomizes the material and liquid, and the particle size of the droplet can be adjusted by changing the gas-liquid ratio.
3. The drying tower is mainly composed of tower body, cone bottom, volute, gas distributor, temperature sensor, etc.Evaporation and material properties Design atomization radius, residence time and air volume. In order to avoid material splashing during reclaiming.The drying tower is operated with slight negative pressure. The upper part of the drying tower is the inlet of the hot air, which is equipped with a volute and a hot air distributor. The hot air is evenly distributed through the hot air distributor and exchanges heat evenly and efficiently with the mist droplets, so that the mist droplets are dried into dry powder products. The temperature sensor is used to record the inlet air temperature and the outlet air temperature.
4. The material recovery system consists of a cyclone separator and a bag filter. After drying, the gas carrying dust enters the cyclone separator, and the gas-solid separation is carried out by the cyclone. The powder enters the barrel and the gas is discharged from the air outlet and enters the bag filter. The trace ultrafine powder in the gas is effectively recovered by means of cloth bags.
5. The heating system consists of air filter, blower and explosion-proof electric heater.
6. The piping system consists of induced draft fans and stainless steel pipes.
7. Taking the programmable controller as the center, it controls various important functional devices and fault alarms: there are two modes of automatic and manual control.
