Abstract
The invention relates to a hydrocyclone with an improved structure. The hydrocyclone with the improved structure is characterized by comprising an overflow pipe, a feeding pipe, a cylindrical section, a connection structure, water injection structures, a conical section and an underflow pipe, wherein the overflow pipe and the cylindrical section are connected by welding, the feeding pipe and the cylindrical section are connected by welding, the cylindrical section, the connection structure and the conical section are connected by flanges, two water injection structures are arranged and respectively located at the middle part and the lower part of the conical section, and the underflow pipe and the conical section are connected through a screw thread. According to the improved structure provided by the invention, the service life of the hydrocyclone is prolonged and the corrosion to the equipment is reduced. Since the smooth arc surfaces of the cylindrical section and the conical section of the hydrocyclone replace the original straight line crossing structure, a low pressure region generated by the original transition structure can be avoided, and sequentially, the impact force generated by the low pressure region is reduced; by structure innovation of the hydrocyclone, the fine particle separation efficiency is improved, and the hydrocyclone is compact in structure and convenient to operate.
Description
[technical field]
The present invention relates to the hydrocyclone technical field, specifically, is a kind of improvement structure hydrocyclone.
[background technology]
Hydrocyclone is industrial widely used efficient separation equipment, be under action of centrifugal force, the heterogeneous plant equipment of utilizing density contrast between the material or particle diameter difference to carry out two-phase or multiphase separation has advantages such as easy to operate, that separative efficiency is high, production capacity is big.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 the Flow Field Distribution, is cyclone design and key in application place.Generally speaking, what enter cyclone inside is the heterogeneous fluid of two-phase or three-phase, belongs to complicated multiphase flow motion, and the charging of cyclone simultaneously is shearing rotating flow at a high speed, has finally constituted the inner high shear force of cyclone complicated heterogeneous flow field after the match.
After two-phase or three-phase blending agent tangentially entered the eddy flow chamber by entrance, rotation at a high speed produced strong eddy current in the eddy flow chamber.Under continuous and liquid that come promoted in the back, the liquid in the eddy flow chamber made progress while rotating, moves downward, and its motion path twist.The liquid of rotation enters the awl section downwards, and the internal diameter of cyclone dwindles gradually, and liquid in rotation speed is accelerated relatively.Because two-phase medium exists density contrast or granularity poor, makes the suffered centrifugal force difference of two-phase medium, the lightweight decentralized photo moves to the low-pressure area of near axis, accumulates near axis, moves up while rotating, and discharges from the top overflow pipe; Isolated heavy phase is then discharged by the underflow pipe of bottom, thereby reaches the purpose of separation.
At present, the commercial Application hydrocyclone more and more requires to save energy and reduce the cost, and improves separative efficiency, and is meticulousr to the particle separation diameter requirement, the present invention is directed to these demands, improved the structure of traditional cyclone.Novel cyclone pressure drop is little, energy-conservation, the flow field stable, is suitable for sector applications such as ore dressing, chemical industry, environmental protection, potash fertilizer industry, living worker.
[summary of the invention]
The objective of the invention is to overcome the deficiencies in the prior art, a kind of improvement structure hydrocyclone is provided.
The objective of the invention is to be achieved through the following technical solutions:
A kind of improvement structure hydrocyclone, it comprises overflow pipe, feed pipe, cylindrical section, syndeton, water structure, conical section and underflow pipe; Overflow pipe is connected by welding manner with cylindrical section, feed pipe is connected by welding manner with cylindrical section, cylindrical section, connect by flange between syndeton and the conical section, the number of water structure is two, be separately positioned on middle part and the bottom of conical section, underflow pipe and conical section are by being threaded.
Described water structure is made up of exterior circular column and inner cylinder, is furnished with the tangent line inlet opening at interior cylinder periphery, and exterior circular column links to each other with the water source by pipeline; Water injects cyclone with the hole of certain pressure from inner cylindrical wall.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 the cyclone interior flow field, reduce pressure drag, improve fine grain classification efficiency simultaneously greatly.
Described syndeton is smooth arc surface, and its structure meets the streamline of cyclone inner high speed eddy flow liquid, helps the stable of flow field; Such structure can steady flow condition, prevents the flow field disorder, helps to improve gradation;
Feed pipe and cylindrical section by being welded to connect, make it becoming one structure in process; Connect by flange between cylindrical section, special syndeton and the conical section, last lower flange with bolted together, is finished connection by flange gasket; Overflow pipe and cylindrical section be welding as requested in process, connects one; Underflow pipe and conical section are by being threaded.
Compared with prior art, good effect of the present invention is:
(1) is connected by cyclone shell of column and the smooth arc surface of awl section, the non-fit motion that can avoid fluid to occur owing to the existence of the angle of suddenling change during axially-movable in cyclone influences thereby reduce the turbulent flow that the transition portion stream field causes; The steady flow condition that obtains has reduced the internal friction resistance, has reduced pressure drop.
(2) water structure then is primarily aimed at the boundary layer that forms under the cyclone high reynolds number situation near wall, the existence in boundary layer can cause segment fluid flow directly to enter underflow along wall, thereby cause the fine grained in this part fluid to can not get separating, influence the separating effect of cyclone.Water injection hole by awl section middle part and bottom destroys the boundary layer, makes its small particles obtain again separating.The water injection hole of bottom then fully guarantees fine grain high separating efficiency, improves separation accuracy.
(3) 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 awl 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.
(4) this invention reaches and improves fine grained separative efficiency, compact conformation, easy to operate by the hydrocyclone structure innovation.
