XLP series of closed-cycle Spray Dryer
XLP series of closed-cycle Spray Dryer
Principle
       Closed cycle spray drying system is in a confined environment, medium dry inert gas, N2 generally applicable to organic solvents materials dry materials or toxic gases in the drying process prone to oxidation of the dry material ; The system uses inert gas as the gas cycle, the drying material has a protective effect, the recycling experience in wet gas, Moisture Removing process, media can be reused; nitrogen entering the heater heated drying tower, liquid materials are Lo Centrifugal pump-delivered to the nozzle, the high-speed cycle of liquid atomizer atomized droplets into the drying tower completed heat and mass transfer process, the dry powder materials from the bottom discharge, the evaporation of organic solvent gas in the vacuum blower under the pressure of the gas trapped in the cyclone dust, dust spray tower after the organic solvent saturated by the condenser gas into liquid condensate from the condenser, non-condensable gas as a heating medium for drying Vector cycle in the system to use. And the general conventional centrifugal spray drying is continuously sending exhaust reach Baishi the purpose of this is proof Closed centrifugal spray drying equipment and ordinary centrifugal spray drying equipment a clear distinction between dry drying system N2 medium for the internal pressure for the operation, the pressure to maintain a certain value, if the internal pressure dropped from the transmitter to control the pressure of N2 into to ensure that the system pressure balance.
