DEVICE FOR BUILDING VACUUM IN INDUSTRIAL EQUIPMENT Russian patent published in 2001 - IPC

FIELD: ejector plants. SUBSTANCE: mixing chamber is made with smooth geometrical profile in form of hyperboloid of revolution with simplexes chosen depending on properties, composition of ejected gas and ejecting liquid and temperature and pressure in system found experimentally. where d₁ is diameter of mixing chamber neck; d₂ is diameter of nozzle; d₃ is inlet diameter of mixing chamber; d₄ is outlet diameter of mixing chamber; l₁ is distance from nozzle neck to end face of gas-liquid mixture inlet in mixing chamber; l₂ is distance from neck of mixing chamber to end face of gas-liquid mixture inlet; l₃ is distance from neck to end face of outlet of gas-liquid mixture from mixing chamber. EFFECT: increased ejection coefficient. 3 cl, 1 dwg
