DEVICE FOR CLEANING GAS FLOW Russian patent published in 1999 - IPC

FIELD: cleaning gas flows of drip liquid and mechanical impurities. SUBSTANCE: device includes housing with branch pipes for delivery of gas discharge of separated media, cone-shaped section mounted coaxially relative to inlet branch pipe and made from flexible material; cross-section of this section has form of Archimedean spiral; shape of section in initial state is described by formula in polar coordinates as follows: r = r₁+(r₂-r₁)/L-hϕ/2π; domain of coordinates: , where r₂ is maximum radius of larger base of section; r₁ is maximum radius of lesser base of section; L is length of spiral or section and h is size of slit of Archimedean spiral; arranged inside section is fine filter element connected with outlet branch pipe; axis of housing is turned in vertical plane relative to axis of inlet and outlet branch pipes towards separated admixture discharge branch pipe; inclination is determined by difference of diameter of housing and difference of diameters of gas inlet and outlet branch pipes. EFFECT: enhanced efficiency of separation of gas flow from liquid and mechanical impurities; increased throughput; avoidance of secondary entrainment of liquid and mechanical impurities. 2 cl, 2 dwg
