Existing conventional type cyclone as the described cyclone hydraulic separators of SU997823A patent etc., is generally the cylinder conical structure, and the top is a direct tube section, connects tapering down and be 9~20 ° cone.The cyclone top center is provided with the overflow pipe that an end stretches into some distances in the cyclone.During operation, the feed liquid that contains solid particle (heavy decentralized photo) tangentially enters straight barrel from the separator top.Because the fluid-flow rate that tangentially enters is very fast, in cyclone, forms rotational flow at a high speed, and enter cone downwards along the wall rotation.The centrifugal action that fluid rotation is produced is got rid of the solid particle in the feed liquid to wall, is compiled in cone base then and discharges.After liquid-solid mixture enters cone, have only small amount of liquid to discharge from underflow with solid particle, most liquid is owing to flow section constantly reduces to be compiled in the axle center, then along the rotation of separator axis upwards, discharge from the top overflow pipe, thereby liquid-solid two-phase is separated.Since in the conventional type cyclone, formed Yan Bianbi from top to bottom with along the axle center from bottom to top two vortexs, fluid flow path is long, velocity gradient is big, thereby pressure drop is big, the energy consumption height.Cyclone diameter is excessive, the mobility status generation marked change of device inner fluid, needed fluid rotary speed in the time of can not guaranteeing to separate, and easily produce the short circuit between the rise and fall vortex, separative efficiency is descended significantly, so its diameter generally is no more than 500mm, so need many parallel operations when treating capacity is big.Because liquid form and the speed speed that depends on inlet fluid of fluid in device, when the fluctuation of inlet velocity or flow velocity are low, separative efficiency sharply descends, and flow velocity is when increasing, the operation pressure drop is sharply risen, so shortcoming such as the conventional type cyclone exists also that operational stability is poor, elasticity is little and enlarge-effect is remarkable.
It is big that the goal of the invention of patent of the present invention is to overcome existing conventional type cyclone fluid-pressure drop, the energy consumption height, operating flexibility and treating capacity are little, enlarge-effect significantly reaches the shortcoming of operational stability difference, it is simple, easy for operation to seek a kind of novel structure of design and manufacture, and fluid shear stress and pressure drop are little, energy consumption is low, strong and the spiral liquid circulation liquid-solid separator with big operating flexibility of stability.
In order to realize the foregoing invention purpose, main body of the present invention adopts metal material to make the sleeve cone structure through machining, mainly containing parts such as inner barrel, outer cylinder body, conic tube, underflow delivery pipe, underflow adjustable ring and inlet tube, center overflow pipe forms, its concentric and the middle inside and outside cylindrical shell that leaves spacing will be divided into first separation district, circulation channel and secondary separation district in the whole device, inside and outside cylindrical shell is connected by support and is concentric body; Connect with the footpath conic tube in outer cylinder body lower end system, its underpart is shaped on the underflow delivery pipe and with the underflow adjustable ring of tapering, the center overflow pipe stretches into outer cylinder body from the top but do not insert inner barrel; Inner barrel is the cylindrical drum of open at both ends, and inlet tube passes the outer cylinder body level or is inclined upwardly and tangentially inserts described bottom with cylindrical shell; Can open a plurality of tangential discharge grooves of system on inner barrel top all around, so that heavy dispersion flows to annular space before rotation rises to the top.During lock out operation, feed liquid enters inner barrel and does the rotation ascending motion with tangential manner from inner barrel lower inlet pipe, after feed liquid enters inner barrel, because cross section sudden enlargement, upwards the axial velocity that flows reduces, and contained bigger solid particle directly sinks to the conic tube bottom in the charging under the gravity effect; The solid particle of intermediate diameters owing to centrifugal action is thrown toward the inner core body wall, enters conic tube along the sedimentation of inner core body wall then when doing the rotation ascending motion with liquid; Less solid particle is thrown toward the annular space between inside and outside cylindrical shell after screwing out the inner barrel upper end with fluid, enters conic tube under together with partially liq circulation.Fluid is done the rotation descending motion in conic tube, make circulation and under less solid particle and liquid in conic tube, obtain secondary separation, the liquid that is separated returns inner barrel along the rotation of conic tube axis, final solid particle is in conic tube bottom enrichment, and by the discharge of underflow delivery pipe, thereby liquid-solid two-phase is separated.
Patent of the present invention compared with prior art has novel structure, and glide path is short, and current gradient is little, and shear stress is little in the fluid, the little efficient height of pressure drop, outstanding advantage such as energy consumption is low, and enlarge-effect is little, and treating capacity is big, and the strong and elasticity of operational stability is big.
