VACUUM PUMP OPERATION METHOD Russian patent published in 2000 - IPC

FIELD: vacuum technology; cleaning of natural gas in absorbent regeneration system and other industries where vacuum technologies can be used. SUBSTANCE: trapped liquid from vacuum pump at outlet circulation tank is delivered through hydraulic lock to inlet of separating reservoir into which steam condensate from desorber flows down through cooler. Gas and steam phases from reservoir are sucked out by vacuum pump through ejector. Gas-water mixture from pump is directed into circulation tank. Exhaust pump feeds vacuum pump and ejector installed on suction pipeline of pump with substance from separating reservoir in required amount. Such design provides reduction of temperature at inlet of pump and maintains required level of vacuum in system. EFFECT: reduced consumption of service water and cost of cleaning of drain. 1 dwg
