Air extractor

Abstract

Abstract PURPOSE: To shorten the startup time of the plant while dispensing with the air ejector by two systems; one for continuously feeding confining water to a vacuum pump from a replenishing water feeder and the other for recovering thereof to a replenishing water tank. CONSTITUTION: Branched off a replenishing water piping 28 to a condenser 3, a confining water piping 12 is provided to feed a confining water type vacuum pump with water fed to a replenshing tank as the confining water supply source to the vaccum pump. The confining water piping is provided with a confining water feed pump 23 and a confining water regulating valve 20 to continuously feed the vacuum pump with the confining water. In addition, the confining water discharged with air extracted by the vacuum pump is withdrawn by a confining water recovery pump 21 carried on a confining water recovery piping 22 connected to the bottom of a demister 4 and returned to the replenishing water tank 18.
