Tornado-flow separator with raw-gas precleanser
Abstract
Abstract A DUST-FROM-GAS SEPARATOR OF THE TONADO-FLOW TYPE HAS ITS ROW-GAS INLET EQUIPPED WITH A DEVICE FOR PARTIALLY PRECLEANING THE ENTERING GAS FLOW. THE DEVICE COMPRISES A FLOW-GUIDE STRUCTURE SHAPED AS A BODY OF ROTATION AND COAXIALLY MOUNTED IN THE GAS INLET DUCT SO AS TO LEAVE AN ANNULAR INTERSTICE IN WHICH A COAXIAL GROUP OF GUIDE VANES PROVIDES A HELICALLY TWISTING PATH FOR THE GAS FLOW. AN AXIAL TUBE OF SMALLER DIAMETER THAN THE GAS INLET DUCT HAS ITS INLET OPENING SITUATED BEHIND THE VANES AND RECEIVES THE PRECLEANED PARTIAL CURRENT OF GAS WHICH FLOWS NEAR THE AXIS OF THE DUCT, WHEREAS THE MORE HEAVILY DUSTLADEN OUTER PORTION OF THE GAS F LOW ENTERS INTO THE TORNADO-FLOW SEPARATOR VESSEL PROPER.
