DEVICE FOR HOT WATER DEGASSING Russian patent published in 2003 - IPC

Abstract RU 2196737 C2

FIELD: equipment for water purification from dissolved gases; applicable in industrial and municipal heating systems for removal of dissolved gases in systems of hot water supply. SUBSTANCE: device consists of degasser body to whose evacuated cavity, water to be degassed is supplied from atop. Water is evaporated and degassed. Formed air-steam mixture is sucked out through flash steam cooler by suction system which is rated for maximum inflow of air-steam mixture. Suction system is made in the form of two parallel circuits. Each circuit has water-air ejector. Working fluid flow rates differ for ejectors by a factor of 10-15. Each ejector has its feed pump. Low-capacity pump of water supply to working nozzle of water-air ejector operates continuously under pressure conditions, and ejector itself, under conditions of ejection. Electric drive of high-capacity pressure pump is started and stopped by signals from column water level alarm. EFFECT: increased economic efficiency of operation of air-steam mixture suction system and higher economic efficiency of entire degassing device operation. 2 dwg
