The drawing explanation: 1 is the cyclone separator body, and 2 is conical pipe, and 3 is the separator feed tube, and 4 is the separator overflow pipe, and 5 is the end mouth of separator conical pipe, and 6,8 is the tube connector of conical pipe and sand storing machine, and 7 is sand storing machine, and 9 for putting the sand valve.
The specific embodiment
Below be used to further specify the device that the utility model is described by concrete embodiment, but and do not mean that the utility model is confined to these embodiment.
Consult Fig. 1 and Fig. 3, a kind of hydrocyclone is made up of separator, conical pipe and sand storing machine.On the intermediate body member 1 of separator expanding chamber is arranged, there is the overflow pipe 4 of lightweight phase the top of expanding chamber, and the spiral cavity that makes the fluid that enters from feed tube form eddy flow is arranged in the expanding chamber, and the sidewall of expanding chamber has tangential feed tube 3.Conical pipe 2 big ends up, the big end of conical pipe is connected with the lower end of separator.Sand storing machine is arranged on the below of conical pipe, and sand storing machine 7 is connected with the following bottom mouth 5 of conical pipe.The diameter of the expanding chamber of separator is identical with the diameter of the big end of conical pipe.The top of sand storing machine and the lower end of conical pipe have 6,8, two tube connector clampings of tube connector of tubulose respectively.The top of sand storing machine is cylindrical shape, and the bottom of sand storing machine is taper.Put sand valve 9 in the tip of sand storing machine conical bottom, adorn valve herein, sand speed is put in control.
Adopt the transition of Archimedes's streamlined to be connected between the eddy flow desanding device of present embodiment, the feed tube of described separator and expanding chamber, reduce the fluid hydraulic loss of import.Sand storing machine drum diameter is 2.3 times of separator diameters, and the lower end is a pyramidal structure, provides enough heavy particle storage area and separators to be fixed together.
For improving separative efficiency, the design of sand storing machine also is a key: the cylindrical portions may diameter is 2.3 times of cyclone separator expanding chamber diameter, it highly is 0.5 times of diameter, the tapering of sand storing machine conical section is greater than the tapering of Taper Pipe, so both increased the stability of solid phase in sand hopper, enough centrifugal force is arranged again, is very effective to improving separative efficiency.Make a liquid-solid separation device by Fig. 1, adopt forging type to make a separator body, conical pipe.This height of separator is 1.2 times of its diameter, and the conical pipe height is 3 times of its diameter.Sand storing machine 7 drum diameters are 2.3 times of separator diameter, highly are 0.5 times of its diameter.Sand storing machine cone height is 0.8 times of diameter, separator body and conical pipe are connected to flange or bolt mode, be sealed into asbestos pad, the coupling part connected mode is flange, bolt also on conical pipe and the tube connector 6, is sealed into asbestos pad, and 6 and 8 is the clip mode, middle is that the polytetrafluoroethylene (PTFE) pad seals, sand storing machine 7 and tube connector 8 are pipe thread seal, and it is fixing that the sand storing machine bottom has valve, package unit to be contained on the support.As to adopt running water be fluid, adds 40-60 order sand 1500g, 60-80 order sand 1500g, and the following sand 500g of 80 orders, flow is 9m
3/ h, desanding efficiency reaches 95%.
Consult Fig. 2, the multistage eddy flow desanding device of present embodiment is made up of the two-stage hydrocyclone.The separator overflow pipe of upper level eddy flow desanding device by a pipeline and next stage eddy flow desanding device the separator feed tube be connected.On the pipeline between the two-stage hydrocyclone, also be provided with tubing pump 10, its objective is the increase flow velocity, strengthen centrifugal force, improve separative efficiency.This apparatus structure compactness, the following sand separation efficient of 100 orders can reach about 95%.
If the ratio of oil strengthens in the profit two-phase, the single-stage separator does not reach 90% desanding efficiency, just add the one-level separator again, adopt the device of two-stage embodiment 2 exactly, the first order is separated the fine grained that does not fall separate in second-stage separation device, the separative efficiency that improves the following sand of 100 orders reaches more than 90%.As profit sand three-phase mixture, water is 6.5m
3/ h, oil is 2.5m
3/ h, sand are 40-60 order sand 1500g, 60-80 order sand 1500g, and the following sand 500g of 80 orders, desanding efficiency is 94.7%.
In the present embodiment, remove the fine grained sand that does not fall and enter into the next stage separator, so just one-level is separated the fine grained sand that does not fall and separated, improved whole separative efficiency by second-stage separator.If most ofly before entering second-stage separator separate than coarse granule sand, small part fine grained sand need strengthen centrifugal force and could remove smoothly, will strengthen flowing velocity before advancing secondary, increases liquid-solid separating power and adds a tubing pump.
