Closed Spray Dryer For Organic Solvents

Equipment function and principle introduction This device is especially for organic solvents, and uses the inert gas medium formed by circulating nitrogen to replace the usual air medium for spray drying. In addition to recovering products, organic solvents can also be recovered. According to the relevant characteristics of organic solvents, a set of closed cycle spraying system is specially designed. The new equipment developed by our company does not necessarily need to reach the boiling point for evaporation, as long as the alcohol in the external air does not reach saturation.

DESCRIPTION

The device is especially for organic solvents, and uses the inert gas medium formed by circulating nitrogen to replace the usual air medium for spray drying. In addition to recovering products, organic solvents can also be recovered. According to the relevant characteristics of organic solvents, a set of closed cycle spraying system is specially designed. The new equipment developed by our company does not necessarily need to reach the boiling point for evaporation. As long as the alcohol in the external air is not saturated, the alcohol can also evaporate at 30-40 degrees Celsius. Based on this principle, our company has developed a set of closed cycle spray dryers that can evaporate in low temperature environments.

FEATURES

1. The feeding system includes: batching tank, solvent tank, feeding peristaltic pump, feeding pipeline, and atomizer. Firstly, the configured slurry is put into the batching tank, and after stirring evenly, the slurry is driven by the peristaltic pump. The road valve reaches the atomizer. The atomizer needs to be equipped with LABOAO's special explosion-proof atomizer nozzle. The life of the nozzle is guaranteed for one year.

2. The heating system consists of a nitrogen-electric heating system. The closed heating element directly heats the drying medium (nitrogen) in the pipeline and passes through a set of pressure regulating control devices. The temperature control accuracy is within ±2°C, and the maximum temperature of the heater is 110 °C.

3. The drying tower includes: tower body, explosion-proof lighting, gas distributor, temperature control equipment, pressure relief device, air inlet pipeline, air outlet pipeline, oxygen content measurement sensor and other components, and a filter device needs to be installed inside the air inlet pipeline; The atomized slurry is heated by the hot air, and the slurry is volatilized and dried to become a powder that falls to the outlet at the bottom. The gas is discharged from the exhaust pipe for closed-circuit circulation. The material of the drying tower is 304 stainless steel.

4. The gas discharged from the bottom of the drying tower contains powder and organic solvent vapor, which is recovered by a filter device, the powder and organic solvent gas are separated, the powder is recovered, and the organic gas enters the condenser for recovery and reuse.

5. The gas cycle is completed by a set of circulating fans. The drying medium is output from the circulating fan, flows through the condensing device, electric heater, drying tower, cyclone separator or bag filter, and then returns to the circulating fan for reuse, forming a gas circulating system.

6. The condensing system consists of a refrigeration unit, a condenser, a refrigerant circulation pump, a filter, a heat exchanger and connecting pipelines. The "wet" gas (including evaporated organic solvent vapor) discharged from the dust collector enters the condenser, and the gas is cooled by the condenser to remove liquid and then returns to the gas circulation system. The organic solvent vapor is condensed and recovered through the liquid level control at the bottom of the condenser The device is automatically discharged into the solvent tank, and the condensation temperature is ≤12°C.
