Description
Technical field
The present invention relates to liquid-solid separation equipment technical fields, specifically, being a kind of low-resistance for liquid-solid two-phase separation
Efficient hydrocyclone.
Background technology
So far, the application of hydrocyclone has more than 100 years history.Why hydrocyclone is in chemical work
The fields such as industry, petroleum industry, light industry, environmental protection are applied such extensive, are attributed to the fact that its some outstanding advantages, such as structure letter
It is single, compact, it is of low cost, it is easily installed and operates, with little need for maintenance and auxiliary device, although small, handle energy
Power is big.Traditional hydrocyclone is usually the simple structure of " column one cone ", and separative efficiency almost has reached bottleneck.Usually
In the case of, short-circuit flow is the upset operation phenomenon of hydrocyclone, directly results in overflow pipe " overflow is run thick " and separation
Large or fine granule mixes in product, seriously affects the separative efficiency of hydrocyclone.The presence of short-circuit flow and the structure shape of overflow pipe
Shape is closely related, and the overflow pipe of conventional hydrocyclone how is creatively transformed, this is still a difficulty in separation equipment field
Topic.Meanwhile the pressure drop of hydrocyclone sometimes up to 200 kPa, and the hydrocyclone of commercial Application usually requires to be permitted
Multiple devices produce simultaneously, therefore energy consumption problem is very important, and at present in the invention and improvement of hydrocyclone, for its point
To be more than the optimization to pressure drop from the research that efficiency improves, therefore, the problem of pressure drop of hydrocyclone also can not be ignored.
Invention content
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of high-efficiency low-resistances for liquid-solid two-phase separation
Hydrocyclone.
The purpose of the present invention is achieved through the following technical solutions：
A kind of hydrocyclone of high-efficiency low-resistance, which is characterized in that include feed pipe, cylindrical section, composite structure, overflow pipe, circle
Bore section and underflow pipe；On cylindrical section top, feed pipe is set in tangential direction；Composite structure in cylindrical section is hollow-core construction, on
Portion is that circular platform type lower part is cylindrical type, and center line is overlapped with hydrocyclone center line；Overflow pipe is " L " type hollow pipe,
The cylindrical section of composite structure is stretched on top, and lower part exceeds hydrocyclone conical section, is drawn in underflow pipe lateral opening hole；In circular cone
Section bottom is provided with rectangular shaped slot.
Further, the composite structure is made of hollow round table and cylinder, and wherein the height ratio of round platform and cylinder is 1:
3-3:1。
Further, the diameter of the cylindrical section of the composite structure and the diameter ratio of hydrocyclone body cylindrical section are
0.2-0.8。
Further, the rectangular channel hole count of the conical section bottom is 2-8.
Further, the cylindrical section of of length no more than composite structure of composite structure is stretched on described " L " type overflow pipe top.
Further, described " L " the type overfall tube diameter is 0.5-0.95 with composite structure middle cylindrical section diameter ratio.
Compared with prior art, the positive effect of the present invention is：
（1）By the composite structure in cylindrical section, the short-circuit flow of fluid is effectively prevented.Short-circuit flow is to enter water from feed pipe
The fluid of power cyclone is detached not along the flowing of hydraulic cyclone wall downward spiral, but is directly entered overflow pipe and is overflow
Go out, to influence separative efficiency.Composite structure in the present invention covers overflow pipe entrance, to make to enter waterpower from feed pipe
The fluid of cyclone flows downward along hydraulic cyclone wall, will not be expelled directly out into overflow pipe, it is therefore prevented that short-circuit flow improves
The overall separation efficiency of hydrocyclone.
（2）Composite structure in the invention is inverted " column wimble structure ", when the smaller component of density in two phase flow along
When the lower end that overflow pipe rises to the composite structure enters cylindrical section, it is equivalent to and enters a small hydrocyclone, then
Cylindrical section and conical section of the eddy flow Jing Guo the composite structure are detached successively, and the hydrocyclone than traditional structure increases one
Secondary separation process improves the separative efficiency of hydrocyclone.
（3）In common hydrocyclone, the larger component of the density that is separated in contour stealth with along center line to
The component that the density of upper movement is smaller is easy back-mixing near conical base so that the component being separated has part, and back-mixing exists again
Together, the separative efficiency of hydrocyclone is reduced.In the present invention, the larger group branch of the density that is separated in contour stealth
Enter underflow pipe by four symmetrical rectangular shaped slots that conical section bottom is opened, to reduce the chance that two kinds of components are met, subtracts
Few air-teturning mixed phenomenon, improves separative efficiency.
（4）The invention greatly reduces pressure by increasing the composite structure of cylindrical section and overflow port being changed to " L " type
Drop reduces energy consumption.
Description of the drawings
Fig. 1 is a kind of structural schematic diagram of the hydrocyclone of high-efficiency low-resistance proposed by the present invention.
Wherein, 1 is feed pipe, and 2 be cylindrical section, and 3 be conical section, and 4 be conical section bottom slot, and 5 be underflow pipe, and 6 be group
Structure is closed, 7 be " L " type overflow pipe.
Specific implementation mode
Hydrocyclone cylindrical section 2 a diameter of 50 mm, high 70 mm, 267 mm of conical section height used in the present embodiment,

0.5 times of 3 diameter of hydrocyclone body cylindrical section.7 top of " L " type overflow pipe stretches to the one of 6 cylinder height of composite structure
At half position.Liquid-solid two-phase mixture in the present embodiment is water-sand two-phase mixture, wherein sandd 50=14.32 μm。
Slush pump conveys water-sand two-phase mixture into hydrocyclone via feed pipe 1, and mode of entrance is horizontal cutting
To.Water-sand two-phase mixture is rotated in hydrocyclone high speed, and the larger component of density is under the influence of centrifugal force radially
It moves out, while being moved downward along hydraulic cyclone wall, underflow pipe 5 is entered via four slots 4 of 3 bottom of conical section
Discharge；Light component is moved to central axial direction, and forms one inward eddy moved upwards in 7 periphery of " L " type overflow pipe, should
Inward eddy, which enters in composite structure 6, continues to carry out secondary separation under the influence of centrifugal force, and heavy phase therein will be tied via combination
6 lower end of structure enters hydrocyclone main body and continues to detach, and light phase enters " L " type overflow pipe 7 and is discharged.The structure of this hydrocyclone
So that material has carried out cyclonic separation twice in the same equipment.
It is tested using a kind of hydrocyclone of high-efficiency low-resistance proposed by the present invention, the hydraulic cyclone with traditional structure
