AIR FILTER Russian patent published in 2002 - IPC

FIELD: different branches of industry, large-size compressor stations with considerably daily compressed air flow rate+ADs- cleaning of compressed air from mist. SUBSTANCE: proposed filter has housing with conical bottom provided with hole in lower part, cleaned air let out union encased with wire gauze and provided with conical head with radial grooves on external surface, unions to let in air to be cleaned made in form of convergent subsonic nozzles with curvilinear grooves on internal surface and provided with metal gauzes at inlet, steam trap placed in bottom hole deflecting partition spring-loaded from side of cleaned air outlet union by means of springs installed on guide rods. Housing of convergent nozzles is bimetallic and is provided with ring groove found on internal surface of convergent nozzles from side of metal gauzes. Ring groove is connected with curvilinear grooves which have dovetail profile. Invention provides reduction of power taken for production of compressed air by increasing efficiency of resonance supercharging in compressor plants operating in industrial zones with large amount of solid and drop-like particles in sucked-in atmospheric air which is obtained by provision of standard parameters as to contamination of air getting into resonator. EFFECT: reduced power consumption, improved cleaning of air. 2 dwg
