EJECTION UNIT FOR FILTER REGENERATION Russian patent published in 1995 - IPC

FIELD: jet apparatus. SUBSTANCE: ejection unit consists of nozzle, mixing chamber and diffuser. Ratio of mixing chamber length to its diameter is 2.3 to 2.7. Distance from nozzle edge to mixing chamber is 3.5 to 3.7 x (D_miaingchaber -D_noggle), where D_{miaingchamber} is diameter of mixing chamber and D_noggle is diameter of nozzle. Desirable effect is obtained with the aid of reverse pulse blowing by means of optimal filter ejection unit provided with filter cartridges. Degree of filtering surface regeneration ranges within 95 to 98%. EFFECT: improved efficiency, uniform regeneration, stable repeatability of results. 1 dwg
