Product DescriptionMulti effect water distiller IntroductionQualified feed water is pressurized by sanitary multistage pump, then enters condenser, and then enters each effect preheater in turn (feed water is heated by secondary steam and distilled water in condenser, then is heated by condensed water of secondary steam in each effect preheater, and is heated by industrial steam condensed water in primary effect preheater), and then enters the primary effect evaporator, where it is sprayed on the inner wall of heating pipe through feed water distributor, and the feed water flows in film form on the pipe wall, And is heated and vaporized by industrial steam. The generated secondary steam with water droplets enters the steam water separation unit from the lower end of the evaporation chamber, the separated pure steam enters the next effect as heating steam, and the raw water that has not been evaporated enters the next effect. Repeat the above process. The pure steam generated by the final effect enters the condenser and joins with the condensed water from all effects except the first effect for cooling. After the non condensable gas is removed, it becomes injection water. The WFI outlet is subject to on-line conductivity detection. The qualified distilled water is output as injection water, and the unqualified distilled water will be discharged.Working principleThe qualified feed water (conductivity ≤ 2 μ s / cm) is pressurized by the sanitary multistage pump, enters the condenser through the flowmeter for heat exchange, then enters the preheater of each effect in turn, and then enters the evaporator of the first effect. The feed water is sprayed on the inner wall of the heating pipe through the feed water distributor, so that the feed water flows in a film in the pipe, and is heated and vaporized by the steam from the boiler, The generated secondary steam with water droplets becomes pure steam after three-stage separation and the raw water that has not been evaporated enters the next effect after separation. The above process is repeated. The principle of other multiple effects is the same as that of the first effect. Only the first effect heating steam is provided by the boiler, so the condensed water of this effect cannot be used as distilled water and should be discharged. The condensed water of other effects is condensed by pure steam, and the pyrogen has been removed, so it can be used as qualified distilled water. In addition, the residual water of each effect must be discharged as sewage because it carries all the impurities and pyrogens in the feed water; The pure steam produced by the end effect enters the condenser and is mixed with the condensate from each effect for cooling. After the non condensable gas is removed, it becomes water for injection, with a temperature of 92-99 ℃.
