Description

Novel high efficiency axial flow hydrocyclone
Technical field:
The utility model relates to a kind of liquid-solid, liquid-liquid gentle-heterogeneous separatory hydrocyclones such as liquid are applicable to industries such as oil, chemical industry, environmental protection, medicine, food.
Background technology:
Simple in structure, the convenient operating maintenance of hydrocyclone is widely used a kind of equipment in the heterogeneous separation processes such as liquid solid, liquid liquid.Present widely used hydrocyclone is formed by tangential admission mouth, overflow pipe, shell of column, cone and underflow pipe, and wherein feeding part is generally tangential admission, and the overflow pipe outer wall is generally cylindrical.
Hydrocyclone with tangential admission mouth exists that energy consumption height, separative efficiency are not high, difficulty of processing is big, machining accuracy is difficult to guarantee and cyclone cylindrical shell top is easy to generate problems such as wearing and tearing, forms such as the charging of general at present employing camber line, involute charging cut down the consumption of energy, improve separative efficiency, but energy consumption is still higher, and difficulty of processing increases, machining accuracy is difficult for guaranteeing.
The hydrocyclone overflow pipe inserts shell of column and partly is generally cylindricality, because the distribution relation of cyclone internal pressure field, the overflow pipe outer wall is smooth in addition, in the hydrocyclone course of work, inside inevitably exists short-circuit flow, drains through overflow pipe thereby make many heavy phase particles just directly enter overfall without separation.At present, people's short-circuit flow of generally adopting the heavy wall overflow pipe to reduce cyclone inside improves separative efficiency.Yet test shows, even adopt heavy wall overflow pipe structure, because the distribution relation of cyclone internal pressure field still has a large amount of heavy phase particles and drains with short-circuit flow.And when adopting common heavy wall overflow pipe, behind mouth at the bottom of the arrival of the upstream in the cyclone overflow pipe, because the existence of overflow pipe wall thickness, radius can impact overflow pipe bottom anchor ring (flow velocity is higher) greater than the upstream in the zone of 1/2nd overfall internal diameters, cause the disorder of local flow field, the stability in eddy flow flow field in can having influence on again simultaneously, thus efficiency of hydrocyclone greatly influenced, especially true for small diameter cyclone.
Summary of the invention:
The purpose of this utility model provides a kind of high efficiency axial flow hydrocyclone easy, that energy consumption is low, separative efficiency is high, operating flexibility is big, the dust-laden fluid is few to cyclone top cylindrical shell wearing and tearing of processing.
The purpose of this utility model realizes by following measure: cyclone is made of feed cavity, guider, overflow pipe, cylindrical shell, cone, underflow pipe etc., it is characterized in that: charging aperture is provided with guider, the guider runner is made up of helicla flute or helical blade, and the overflow pipe lower end is a scrobicular ring face.
Because the designed guider runner of the utility model is made up of helicla flute or helical blade, the fluid that axially enters is quickened to turn to, press the certain angle ejection at the runner exit place, at the inner high speed rotational flow field that forms of cyclone, increased the axial migration velocity of medium, thereby reduce the ring-type eddy current of cyclone inside, reduce the cyclone energy consumption.The design of the scrobicular ring face of overflow pipe lower end has been avoided upstream that the impact of overflow pipe bottom anchor ring is caused and produced the disorderly phenomenon of local flow field near mouth at the bottom of the overflow pipe, has kept the stability of cyclone interior flow field.
Description of drawings:
Fig. 1 is the axial-flow type hydrocyclone structure full sectional view that proposes according to the utility model;
Fig. 2 is the cutaway view of axial-flow type hydrocyclone shown in Figure 1 along the A-A line;
Fig. 3 is the front view of the guide structure schematic diagram of the axial-flow type hydrocyclone that proposes according to the utility model;
Fig. 4 is the vertical view of the guide structure schematic diagram of the axial-flow type hydrocyclone that proposes according to the utility model.
The specific embodiment:
Below in conjunction with accompanying drawing, structure of the present utility model and work characteristics are described further.
The utility model is made of feed cavity 1, guider 2, overflow pipe 3, cylindrical shell 4, cone 5, underflow pipe 6 etc., and guider outer ring surface and cylinder inboard wall closely cooperate, and inner ring surface overlaps with the overflow pipe external diameter; Bottom scrobicular ring face structure is positioned at guider runner exit downside, for circular arc line or parabola form around the rotation of cyclone axis.
During work, mixed liquor enters guider 2 runners vertically by feed cavity 1, under the effect of guider 2, in cyclone, form a centrifugal force field of rotating at a high speed, wherein heavy phase is descending in the effect lower edge of centrifugal force field and axial compressive force cylindrical shell 4, cone 5, discharged by underflow pipe 6, light phase is then discharged by the overfall of overflow pipe 3.
The runner of guider 2 is formed by helicla flute or helical blade, and the fluid that enters is vertically quickened to turn to, and presses the certain angle ejection at the runner exit place, at the inner high speed rotational flow field that forms of cyclone.This kind structure makes that fluid obtains fully to quicken before entering cyclone inside, because the fluid axial velocity component increases, increased the axial migration velocity of medium simultaneously, thereby reduces the ring-type eddy current of cyclone inside, reduces the cyclone energy consumption.The design of guider multithread road makes the symmetry of cyclone interior flow field and stability strengthen, thereby helps the raising of energy consumption reduction and separative efficiency.This kind structural design also can strengthen the discharge ability of cyclone underflow opening, reduces the generation of cyclone underflow opening clogging.
The terminal scrobicular ring face design of overflow pipe 3 has been avoided producing local flow field disorder phenomenon because upstream causes the impact of overflow pipe bottom anchor ring near mouth at the bottom of the overflow pipe, the stability that has kept the cyclone interior flow field, make to reenter outer eddy flow smoothly, strengthened the secondary separation of fine particle greater than the upstream in 1/2nd overfall inner diameter zone.Simultaneously, upstream can effectively hinder flowing of short-circuit flow again when reentering outward turning circulation and turning to downstream and carry out secondary separation, also reduced overflow to a certain extent and run thick.
Major advantage of the present utility model is:
1. energy consumption minimizing, the pressure loss significantly reduce.
2. disposal ability improves, and compares with diameter tangential admission cyclone, and disposal ability improves 10%~30%.
3. operating flexibility becomes big, separating property is stable.Change under the bigger situation in inlet flow rate, input concentration, feed size distribution etc., can both keep higher separative efficiency.
4. reduced the influence that cyclone cylindrical shell top circulation, import incision are flowed, solid particle significantly reduces the wearing and tearing on cylindrical shell top.
5. the scope of application is wide.The liquid solid, liquid liquid that can be widely used in industries such as oil, chemical industry, environmental protection, medicine, food separates and gas-liquid separation, is particularly useful for that many cyclones in parallelly use, energy consumption is had relatively high expectations, opereating specification changes occasion greatly.
