The specific embodiment
Below in conjunction with accompanying drawing the present invention is described further:
Embodiment 1: as shown in Figure 1, thisly be used for high-gravity rotating bed dish type centrifugate gyration sealing device, and mainly comprise housing 3, rotor 5, rotating shaft 7, sealing device 18; On rotor 5 fixed rotating shafts 7; Housing 3 is placed in rotor 5 outsides, and sealing device 18 tops are fixed on housing 3 upper inside wall, and the bottom is fixed on the rotor upper surface 4 of rotor 5; Fix through welding or with the method for bolted; Bottom one side of housing 3 is provided with gas phase inlet 11, and opposite side is provided with liquid phase outlet 6, and the top of housing 3 is provided with liquid phase inlet 1 and gas vent 2.
The material of going up moving circular discs 13, down moving circular discs 10, quiet circular discs 16, blade 14, lower blade 12, fan blade 15, choke circle 9 and blocking solution dish 17 is a stainless steel, carbon steel, non-ferrous metal, various engineering plastics or fiberglass.Sealing fluid 8 can be a material liquid, also can be to add liquid, comprises the neat liquid of water, the various different viscosities of wet goods, liquid mixture, molten mass, colloidal sol, liquid such as suspension.
When two moving circular discs rotations, the blade of moving circular discs drives sealing fluid 8 and does rotation synchronously.The sealing fluid 8 of rotation produces powerful centrifugal force, reaches the purpose of sealing gas.Because the centrifugal force that the centrifugal force that liquid in rotation produces in the moving circular discs 10 down produces greater than liquid in rotation in the last moving circular discs 13; Liquid can radially inwardly be creeped to be thrown out of until liquid and left sealing device 18 along quiet circular discs 16 upper surfaces, throws away from seal clearance and the blocking solution dish 17 of quiet circular discs 16 can effectively prevent sealing fluid 8.Liquid in rotation also has the fluid vortex that produces radially in the moving circular discs 10 down, and eddy current is gas-entrained and then produce gas leakage, and the choke circle 9 of quiet circular discs 16 at utmost reduces gas leakage.Fan blade 15 rotations that the upper surface of upward moving circular discs 13 is provided with produce blast, increase the sealing load of gas.
Compare with general centrifugate gyration hermetically-sealed construction, the present invention adopts Moving plate structure that is provided with blade and the quiet dish structure that is provided with choke circle 9 and blocking solution dish 17.This structure guarantees that sealing fluid 8 rotates at seal clearance synchronously, produces powerful centrifugal force sealing gas; And can prevent effectively that sealing fluid from throwing away from seal clearance, at utmost reduce gas leakage simultaneously.Simultaneously, sealing fluid 8 is retained in the seal clearance between the sound dish, and sealing fluid 8 can not flow away yet when not rotating.
Rotor 5 is rotation at a high speed under the drive of rotating shaft 7.Gas gets into the housing inner chamber from gas phase inlet 11, under pressure, radially passes rotor 5, in rotor 5, contacts with liquid countercurrent, discharges from gas vent 2 at last.Liquid gets into revolving bed rotor 5 through liquid phase inlet 1, under centrifugal action, throws away, and liquid is ground into fine drop and brin, contacts with back flow of gas, carries out mass-and heat-transfer, discharges from liquid phase outlet 6.Down moving circular discs 10 and blade 12, quiet circular discs 16 and choke circle 9 thereof and blocking solution dish 17, upward the dish type centrifugate gyration sealing device formed of moving circular discs 13 and blade 14 thereof and fan blade 15, sealing fluid 8 plays gas movable sealing effect; Prevent the interior gas of revolving bed housing without rotor, and directly get into gas vent 2 from rotor upper surface 4.
Moving up and down circular discs diameter is 240 millimeters, and quiet circular discs diameter is 200 millimeters.Clearance distance between moving circular discs and the quiet circular discs is 100 millimeters.Moving up and down circular discs respectively is provided with 4 radial blades.Quiet circular discs is provided with blocking solution dish 17 and choke circle 9.When the air leakage of disc-shape centrifugal pendular ring dynamic sealing device is 2 liters/hour, when rotating speed is 800r/min, in the revolving bed housing and the gas pressure drop between the gas outlet tube when being 5.0 kPas; When rotating speed is 1000r/min, in the revolving bed housing and the gas pressure drop between the gas outlet tube when being 62 kPas; When rotating speed is 1200r/min, in the revolving bed housing and the gas pressure drop between the gas outlet tube be 7.3 kPas.
Embodiment 2: as shown in Figure 2, be in series with many groups and embodiment 1 similar rotor 5 and sealing device 18 in the rotating shaft 7, and rotor 5 central authorities are provided with riser 21, and 7 places are provided with drainage tube 20 near rotating shaft, and the port place of drainage tube 20 is provided with cofferdam 19.
With three rotor inlines is the row examples, and a sealing device 18 is respectively installed in the upper surface of three rotors 5.Gas gets into revolving bed housing inner chamber from gas phase inlet 11, and radial flow is crossed the rotor 5 of bottommost, gets into the riser 21 of rotor central authorities, upwards flows, and successively through top two rotors 5, discharges from gas vent 2 at last.Liquid gets into from liquid phase inlet 1, through the rotor 5 of cofferdam 19 with drainage tube 20 entering topmosts, under centrifugal action, throws away, and then successively through following two rotors 5, discharges from liquid phase outlet 6.In three rotors 5, liquid is ground into fine drop and brin, contacts with back flow of gas, carries out strong mass-and heat-transfer.A sealing device 18 is respectively installed in three rotor 5 upper surfaces, prevents that gas from directly getting into from rotor 5 upper surfaces to go up sheaf space and leak gas.
Except that the foregoing description, the present invention can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of requirement of the present invention.
