Abstract
The invention relates to a method and a device for centrifugal settling separation. An open settling separation chamber is formed between an outer rotary cylinder without a bottom and a cover and a central inner rotary cylinder, and the ultraspeed and high-speed rotary motions of the outer and the inner rotary cylinder drive liquid materials to trend towards circular motions at the same speed.

Though gravitation is very faint, the quality of inner rotary member is very big, has galvanic couple to do one's utmost between the atom of outer surface and molecule, makes a concerted effort to show as physical absorption power.Show that outer wall can draw liquid internal layer molecule with fast circular motion.
The liquid of high speed circular motion is in the inertial centrifugal field of force, very high fluid pressure is radially appearring in weight and acceleration, the external rotary member inwall is produced very big centrifugal stress, because the separation chamber is open, liquid upper is an atmospheric pressure, liquid communications and liaison among bottom and the Chu Liuchi, in an open separation chamber, fluid pressure very big between external rotary member inwall and liquid can transmit to the liquid internal all directions, because intermolecular in the liquid have a power transmission effect, the centrifugal stress that the external rotary member inwall bears can be to the transmission of liquid all directions, power upwards is the power that needs in the feed separation process, downward power has been passed to whole liquid, the movement velocity of the power acceleration molecular before the direction of motion, the power after the direction of motion has been passed to whole liquid, and pressure is tending towards distributing according to the depth-averaged of liquid, therefore, the centrifugal stress that is subjected to of external rotary member inwall is exactly the pressure power of whole liquid.What external rotary member applied liquid material is tractive force, and liquid weight is not subjected to bearing capacity.Because inwall bears the centrifugal active force, external rotary member can draw the liquid material circular motion all the time.Therefore, the separation of material of external rotary member traction can be a lot, can turn round in very high speed.Huge centrifugal stress is distributed in the liquid, can design the big diameter of turning.
Material can separate in the separation chamber, and being has different quality because of structure attitude molecule in the liquid or associated matter molecule, and different severe (weight) is arranged in gravitational field, produces different sinking speed.When reaching certain circular motion speed, different displacement vectors is just arranged in the inertial centrifugal field of force, exist the displacement vectorial force poor, when the power difference of displacement vector during greater than the intermolecular association force of different structure attitude, the molecule of different quality will be distributed on the different circuit orbits, what quality was big is tending towards away from the center of circle, and what quality was little is tending towards near the center of circle.Liquid under the constant volume can deformation but mass number is constant, so the molecule of different quality or micel will occupy position separately in gravitational field, and the speed of molecule that severe is big or micel sedimentation is fast, and the sinking speed that severe is little is slow.Gravity is subjected to the centrifugal force effect, and it is directed downwards, thus with waste water in the separation chamber or sewage sedimentation separation.But inertial centrifugal field of force meta moves the separate and subside speed of phasor difference formation and will just show as centrifugal sedimentation and separate much larger than occurring in nature gravitational settling speed.The liquid plane of Chu Liuchi and separation chamber's communications and liaison, owing to exist liquid level poor, the liquid pressurized of a of separation chamber rises, and the clean water of having separated is discharged along outlet i, the soiling solution that concentrates discharges from outlet h.Reach the purpose that different material separates in waste water, the sewage thus.
The innovative point of above-mentioned centrifugal sedimentation isolation technics method is: in the separation chamber material outside, the high speed circular motion under the inner rotary member tractive force, the molecule of different quality or micel trend towards all the time with speed.In open separation chamber, as long as solia particle in the liquid or molecule, micel are made circular motion, centripetal force and equivalent reverse centrifugal inertial force are just arranged, and displacement vector orientation is separately arranged, be equal to existing centrifugal separation technology method.But, owing to adopted and existing centrifugal separation technology distinct methods and constructional device, following outstanding advantage is just arranged:
1. because the open separation chamber of uncovered, the no end that is separated in of liquid material carries out, and outer, inner rotary member is only made circular motion tractive force merit to material, the weight of material is not made the carrying merit, thereby to the separation of different material in the material, need power and less energy consumption.
2. because reative cell is open, the centrifugal stress that the fluid pressure of high speed circular motion acts on the external rotary member inwall can be transmitted in liquid, centrifugal stress and the fluid pressure that bears of turning is tending towards equivalent, the therefore not restriction of liquid body centrifugal pressure of diameter of turning.Existing drum type brake supercentrifuge, huge fluid pressure are subjected to constant volume restriction rotary drum will bear great centrifugal stress.So when same diameter, identical speed, the little several number magnitude of centrifugal stress of turning and bearing than rotary drum, thereby the diameter of external rotary member can make very greatly, the rotating speed of turning can be very high, separation factor can be very big, thereby waste liquid, the output of sewage disposal, efficient are very high.
3. because the positioning action at inner rotary member center, liquid has the automatic aligning effect during with the inner rotary member circular motion, external rotary member is circumferentially to draw acceleration to liquid, and controlled by magnetically confined, thereby separator vibration when operation is very little, need not consider the vibration of separator during design, make simple in equipment, can long-time running, be easy to safeguard that operating cost is low.

Parts G is a cyclelog, collects unit by information and constitutes with the control unit that programs.Information is collected unit to be had: sewage material information a, the Chu Liuchi that enters and the liquid level discrepancy in elevation information b of separation chamber, outer, inner rotary member speed of gyration information c, suspension magnetic gap elevation information d, leakproof gas curtain pressure information e, collect a mouthful width information f, collection bore to positional information g, ejected matter information h.Information word has dependence each other, carries out computer information processing according to aforesaid method principle, and establishment becomes programme-control unit, and the combination of control unit is cyclelog G.
By the centrifugal sedimentation separator that components A, B, C, D, E, F, G form, its operation principle is: the sanitary sewage of city discharging or the waste water of industrial discharge are handled through filter residue at cesspool earlier, remove millimeter above solid particle and waste residue.For accelerating separate and subside speed, the sewage or waste water that minority is difficult to separate will add flocculant, is condensed into micel so that efficient the separation.Sewage or waste water is from flowing into or pump into storage stream pond 73, enters volute chamber 28 by pipeline 32 through import 30 through exporting 33, enters initial velocity chamber 29 by exporting 34.The effect of volute chamber is that the sewage or waste water part that will enter retains, and evenly distributing by circumference outlet 34 enters initial velocity chamber 29, drives liquid material circular motion, accelerated motion by inner rotary member 16.Liquid rises to separation chamber 35, by external rotary member 1 traction liquid material acceleration, ultrahigh speed circular motion.Rotate turn 1 with the support of fixing 27 between, be provided with leakproof gas curtain 37, gas pressure equals or a little more than fluid pressure, prevents liquid leakage.Turn 16 by 72 drives of high speed stepless speed-regulating motor, 12000 rev/mins of governing speed scope 0 ∽ turn 1 by linear synchronous generator (LSM) 54 drives, carry out speed governing by inverter according to the frequency of electric current, velocity of rotation is unrestricted, can obtain very high rotating speed or peripheral velocity.Its angular velocity omega can reach 100～850 revolutions per seconds, linear velocity υ can reach 300～2500 meter per seconds.Outward, inner rotary member counterclockwise in the same way the revolution, the traction liquid material be tending towards with fast circular motion.Different molecular or molecular association complex have different centripetal accelerations and equivalent reverse centrifugal acceleration in the material, and the direction of acceleration is pointed to the center of circle.The different centripetal force of quality are different with equivalent reverse centrifugal inertial force, and the direction of power is justified by oneself outside the mind-set.The material of different quality, all directions displacement vector difference, it is poor to produce displacement vector power, structure attitude in the liquid is intermolecular to be association force, gravitation is arranged between polar molecule, the fluidity determining of liquid be weak adhesion between different molecular, between displacement vector power difference is greater than different molecular during weak adhesion, just different material in the material can be separated, in certain velocity interval, the material that quality is big is tending towards the outside of circle, and the material that quality is little is tending towards the inboard of circle, and the species distribution of different quality is on different circular orbits.During the high speed circular motion, the material of different quality has different Coriolis forces, and in three-dimensional polar coordinates, the direction of power also is a displacement vector power along circumferentially, radially, axially rise, and it has quickened the feed separation process.The material of different quality has different gravity in the material, and it is the attraction of gravitation of occurring in nature, is inertia force, is not the power that the material gyration produces.Different material in the circular motion, the severe of quality different manifestations (gravity) difference, the speed difference that falls, it is downward displacement vector, exist the displacement vectorial force poor, during weak adhesion, the material of different quality produces sedimentation separation, the natural subsidence in the just existing treatment tank between the vectorial force difference is greater than different molecular.Ratio with this natural subsidence speed and centrifuge speeds in the separation machinery is called separation factor, because the acceleration of sedimentation is 9.8 meter per seconds
2Constant value, so the effect of feed separation is only relevant with the speed of material circular motion with efficient, promptly the centrifugal inertial force of different material is relevant in the separation chamber, but the separation of material is material sedimentation and the coefficient result of centrifugal inertial force.Centrifugal force in the separation chamber makes liquid substance produce radially infall process, much larger than liquid substance gravitational settling process.Because external rotary member can reach very high rotating speed or circular motion linear velocity, drawing liquid is tending towards all the time with speed, the centrifugal force that the high more liquid of speed produces is big more, the fluid pressure that inwall is subjected to is big more, the effect of the inwall of turning traction liquid circular motion is good more, and the effect of its sedimentation separation is also just good more.
The separation of liquid material is a quick process in the separation chamber, various materials after the feed separation in time to be discharged, liquid material needs climbing power, lift is derived from the difference in height of Chu Liuchi and both sides, separation chamber liquid, also be that liquid pressure is poor, pressure is equally distributed at the sustained height of liquid, and the liquid of eminence flows into lower, and the liquid of lower has climbing power.The size of lift is highly regulated by 78 pairs of liquid levels 73 of height adjuster.Lid 57 above the separation chamber is provided with several collections mouthful q, collects the size of mouth and can regulate by y, collects the radial position of mouth and regulates by x.Coriolis force and liquid climbing power that the material of high-speed motion has circumference and axially rises, will entering separately automatically through each collection mouthful q, passage w discharges separator by outlet s.
