The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

Efficient rotary beating type separator of the present utility model, shown in Fig. 1-6, it includes cylindrical shell 1, air inlet pipe 2, escape pipe 3, cylindrical shell 1 upper side is provided with air inlet pipe 2, settled the escape pipe 3 that becomes warp in the middle of in the cylindrical shell, outside the pass-out cylindrical shell of escape pipe upper end, a section surface has air deflector 4 therein, and flow straightener 5 is arranged at the bottom in cylindrical shell.The tangent line air intake of its air inlet pipe 1 routine changes hemisection into to air intake structure, be exactly outside a part of air-flow be tangential admission, and the outer surface of upper of a part of air-flow inside and escape pipe 3 is collided, be created in the turbulent flow that collide back and forth on cylindrical shell 1 inwall and escape pipe 3 surfaces, impel liquid mist or droplet or solid particle to be condensed into big drop or bulky grain.The air deflector 4 that the turbine guide vane constitutes is installed in escape pipe 3 middle and upper parts, and it is shaped as "＞" shape, and folding formula in promptly forming can certainly adopt one chip.Like this through the air-flow after the air inlet volley cohesion, change direction toward current downflow, multiple impact must take place in liquid mist and droplet or particulate between "＞" shape turbine guide vane, promoted the liquid mist to become big drop or particle widely with droplet or particle coagulation, and under the rotary centrifugal force effect, big drop is just beaten on the separator cartridge body wall.The pipe lower edge at turbine guide vane place connects with the slope that is connected to of its relative big-inch pipe in bottom, and the air-flow through the turbine guide vane promotes simultaneously that at the change airflow direction drop clashes into mutually with the slope in the air-flow like this, easily is condensed into big drop.The escape pipe upper edge at same turbine guide vane place also connects for the slope with the connection of the relative minor diameter pipe in turbine guide vane top.Air-flow through the slope just begins along the inwall and the rotation of escape pipe outer wall of separator cylindrical shell downward; rely on centrifugal action, isolate drop from air-flow, drop is just beaten under the inwall and following current of cylindrical shell; because with escape pipe is the reducing pipe; cylindrical shell 1 upper semisection is a straight tube, and lower semisection is to expand through pipe, and is progressively to expand through structure; can reduce the air-flow velocity of decline effectively; make the easier landing of particle or drop, prevent back-mixing and taken out of again, improved separating effect.The bottom design and installation of separator flow straightener 5, flow straightener 5 is for umbrella shape radiation shield 7 and connect short 6 down, be evenly distributed with spoiler 8 all around, make that the air-flow that flow to the separator bottom is easier in time to stop the rotation, do not cause sinuous flow, make and separate drop or particle and accumulate in the separator bottom, the air-flow that liquid or liquid foam are difficult for being prepared rising carries away, and the bottom of escape pipe 3 is designed to relative big-inch pipe, and its bore is increased, reduce the flow velocity of ascending air and avoid drop or liquid foam to be taken out of again by air-flow.The inwall of cleaning separator for convenience is provided with scavenge pipe 9 at its oral area, and scavenge pipe 9 arranges around the air inlet pipe oral area, and inner wall surface thereof is distributed with spray orifice 10, can be used for spray Cleaning for High Capacity liquid, reaches and cleans purpose easily.
