NLD Type Internal Spiral Multi-effect Distilled Water Machine
NLD type Internal spiral multi-effect distilled water machine
Multi-effect water distiller (injection water machine)
The Multil-effect distiller water machine is used to produce the injection water in the pharmaceutical, medical, scientific research, electron, biochemical industry. Main Technological Parameters: ROYAL PACKING
(industrial steam pressure 0.3Mpa)
Industrial steam consumption(L/h)
Feed water consumption(L/h)
The qualified water feed water is input the condenser after the increased pressure by multilevel pump and then enters into each preheater (the feed water will be heated by the secondary steam and distilled water in the condenser. In the first stage preheater, the feed water is heated by the industrial steam condensate water. After entering the other stage preheater, it is heated by the secondary steam condensate water). Next the feed water is input into the water distributor of the 1st stage evaporator, which is spouted to the inside of the heating tubes and flows as film. The produced second steam with drips enters into the gas and steam separating setting from the bottom of the heating tubes. The separated pure steam enters into the next stage as heating steam, meanwhile, the feed water, which is not evaporated, enters into the next stage. And then it is repeated as above mentioned process. The pure steam from last stage is converged with each stage condensed water(expect 1st stage), after cooling and drainage of the non-condensable gas,(according to different models, there should be a device for discharging the non-condensable gas continuously) it is the WFI. There is an on-line conductivity test at the output orifice. The qualified distilled water will be output as the WFI, and the unqualified will be discharged.
