DEVICE FOR SEPARATION OF SOLID PARTICLES FROM GAS FLOW Russian patent published in 2003 - IPC

FIELD: separation of solid particles from gas flows; metallurgy; chemical industry; construction engineering; de-dusting of gases for classification of poly-dispersed materials by sizes. SUBSTANCE: proposed device has bent gas duct with gas flow inlet and outlet branch pipes and bin for receiving solid particles; device has housing bent over radius with pipe placed inside it; axis of this pipe is parallel to axis of housing and is shifted towards gas flow inlet branch pipe; pipe has slotted hole; gas flow outlet branch pipe is connected with end of pipe. Ratio of area of pipe section to sectional area of slotted hole is equal to or is lesser than one. Slotted hole is provided with baffle plate mounted on pipe; width of this baffle plate is more than radius of pipe and is lesser than radius of housing. Ratio of sectional area of gas flow inlet branch pipe to sectional area of bin inlet hole is equal to 1: (2-12). EFFECT: reduced overall dimensions ; simplified construction; ease in maintenance. 3 cl, 2 dwg
