SEPARATOR OF SUBMICRON PARTICLES OF OILY FLUIDS Russian patent published in 1999 - IPC

FIELD: mechanical engineering. SUBSTANCE: this relates to devices intended for purification of air from aerosol created from liquid products such as oily and condensation admixtures with dimensions of particles usually not over 1 mcm. Trial investigations and practical application of such devices indicated that in aforesaid systems most efficient is method of settling down suspensions by turbulent coagulation of particles. Separator has flat horizontal receiving header, curved tubes of settling-down band, and flat inclined header for branching out trapped aerosol. Separator of particles is generally made in the form of settling-down band of curved tubes with internal diameter of 8 mm. Ends of tubes are secured in flat headers. Effect of settling down aerosol particles by this separator is same as in direct-flow tube at similar aerodynamic resistance. However in curved tubes due to secondary circulation degree of flow turbulization and consequently intensification of particle coagulation occurs substantially quicker in flow of aerosol because additional resistance at bending points increases total resistance in entire tube. This makes possible to obtain same effect of aerosol settling-down as in direct-flow tube but at considerably less overall length. Aforesaid embodiment of particle separator allows for reducing its overall dimensions, enhancing purification efficiency, returning trapped product to production process, simplifying design of apparatus. EFFECT: higher efficiency. 2 cl, 1 dwg
