Abstract
The utility model relates to an energy-saving hydraulic cyclone which comprises a cylindrical section, an arc-shaped connecting structure, two cylindrical water injection structures and a conical section, wherein the cylindrical section, the arc-shaped connecting structure and the conical section are connected through flanges; the upper and lower flanges are fastened together through a flange gasket by bolts so as to finish connection; the two cylindrical water injection structures are arranged on the middle and lower parts of the conical section, respectively. According to the improved structure, the service life of the cyclone can be prolonged, and the equipment corrosion is alleviated. Because an original linear intersecting structure is replaced by smooth arc-shaped surfaces of the columnar section and the conical section of the cyclone, a low-pressure area generated by an original transition structure can be avoided, so that the impact force generated in the low-pressure area is reduced. According to structural innovation of the hydraulic cyclone, the fine particle separation efficiency is improved, and the hydraulic cyclone is compact in structure and convenient to operate.
Description
[technical field]
The utility model relates to hydrocyclone technical field, specifically, is a kind of energy-saving waterpower cyclone.
[background technology]
Hydrocyclone is industrial widely used efficient separation equipment, under the effect of centrifugal force, utilize density contrast or the poor heterogeneous plant equipment of carrying out two-phase or multiphase separation of particle diameter between material, there is the advantages such as easy to operate, separative efficiency is high, production capacity is large.Be widely used at many industrial circles such as ore dressing, mining industry, chemical industry, petroleum industry, light industry, environmental protection, food, medicine, weavings.
Hydrocyclone is simple in structure, but interior flow field is very complicated, analyzes the inner multiphase flow Flow Field Distribution of cyclone rule, grasps the relation between cyclone parameter and Flow Field Distribution, is the key point of cyclone design and application.Generally speaking, what enter cyclone inside is the heterogeneous fluid of two-phase or three-phase, belongs to complicated multi-phase fluid movement, and the charging of cyclone is simultaneously shearing rotating flow at a high speed, has finally formed the inner high shear force of the cyclone heterogeneous flow field of complexity after the match.
When two-phase or three-phase blending agent are tangentially entered behind eddy flow chamber by entrance, High Rotation Speed in eddy flow chamber, produces strong eddy current.In the back continuously and under the liquid-driving coming, the rotation limit, liquid limit in eddy flow chamber upwards, move downward, its motion path is twist.The liquid of rotation enters cone section downwards, and the internal diameter of cyclone dwindles gradually, and liquid in rotation speed is accelerated relatively.Due to two-phase medium exist density contrast or granularity poor, make the suffered centrifugal force difference of two-phase medium, lightweight decentralized photo moves to the low-pressure area of near axis, is gathered near axis, rotation limit, limit moves up, and discharges from top overflow pipe; Isolated heavy phase is discharged by the underflow pipe of bottom, thereby reaches the object of separation.
At present, commercial Application hydrocyclone more and more requires to save energy and reduce the cost, and improves separative efficiency, and meticulousr to particle separation diameter requirement, the utility model, for these demands, has improved the structure of traditional cyclone.Novel cyclone pressure drop is little, energy-conservation, flow field stable, is suitable for the sector applications such as ore dressing, chemical industry, environmental protection, potash fertilizer industry, raw work.
[utility model content]
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of energy-saving waterpower cyclone is provided.
The purpose of this utility model is achieved through the following technical solutions:
A kind of energy-saving waterpower cyclone, it comprises cylindrical section, the syndeton of circular arc, columniform water structure and conical section; Cylindrical section, connects by flange between the syndeton of arc surface and conical section, and upper lower flange is by flange gasket, with bolted together, complete connection; Two columniform water structures are separately positioned on middle part and the bottom of conical section.
Described cylindrical section is connected by welding manner with overflow pipe.
Described cylindrical section is connected by welding manner with feed pipe.
Described conical section and underflow pipe are threaded connection.
Described columniform water structure is combined by exterior circular column and inner cylinder.In addition, be furnished with tangent line inlet opening at interior cylinder periphery, exterior circular column is connected with water source by pipeline; Water injects cyclone in the hole from inner cylindrical wall with certain pressure.The area of water inlet is certain, along with the difference of cyclone treating capacity, adopts different flow velocity reinforced separating effects; These improvement can be stablized cyclone interior flow field, reduce pressure drag, greatly improve fine grain classification efficiency simultaneously.
The syndeton of described circular arc is smooth arc surface, and its structure meets the streamline of cyclone inner high speed eddy flow liquid, contributes to the stable of flow field; Such structure can steady flow condition, prevents flow field disorder, contributes to improve gradation.
Feed pipe and cylindrical section by being welded to connect, make it becoming one structure in process; Between cylindrical section, special connecting structure and conical section, connect by flange, upper lower flange is by flange gasket, with bolted together, complete connection; Overflow pipe and cylindrical section be welding as requested in process, is integrally connected; Underflow pipe and conical section are threaded connection.
Compared with prior art, good effect of the present utility model is:
(1) is connected by cyclone shell of column and the smooth arc surface of cone section, the non-fit motion that can avoid fluid to occur due to the existence of the angle of suddenling change when axially-movable in cyclone, affects thereby reduce the turbulent flow that transition portion stream field causes; The steady flow condition obtaining has reduced internal friction resistance, has reduced pressure drop.
(2) improve the corrosion that structure can improve the service life of cyclone and reduce equipment.Because cyclone shell of column and the smooth arc surface of cone section replace original straight line intersection, the low-pressure area that can avoid original transition structure to produce, thus reduce the impulsive force that low-pressure area produces.
(3) this utility model, by hydrocyclone structure innovation, reaches and improves fine grained separative efficiency, compact conformation, easy to operate.
