VACUUM DEAERATOR Russian patent published in 1997 - IPC

FIELD: deaeration equipment. SUBSTANCE: invention relates to vacuum deaerators for removing corrosive-aggressive gases from feed water at heat power stations. Deaerator has an upright housing with fittings for entering water, bubbling steam, and for discharging deaerated water and steam-gas mix. Housing encloses jet section with distribution plate and bubbling section including bubbling sheet, overflow tube, and water-drain sill. Deaerator has additionally formed attachment and intermediate sections disposed in series between jet and bubbling sections. Additionally installed are also vertical steam-gas removing pipes. Attachment section is made as coaxial with housing cylindrical space filled with charge in the form of Rashig's rings. In the hollow of intermediate space, a horizontal bypass plate is installed coaxially with housing, which is provided with fitting for feeding blowing steam. Into bubbling section, water branch pipe with fastened to it swirl cones is inserted. Water branch pipe and cylindrically-shaped water-drain sill are installed coaxially with housing on bubbling sheet. Intermediate and bubbling sections are interconnected through water branch pipe, and jet and bubbling sections are interconnected through vertical steam-gas removing pipe. EFFECT: improved design. 2 cl, 1 dwg
