Abstract

The utility model relates to a high-efficiency hydrocyclone. The hydrocyclone comprises a first tapered pipe, a second tapered pipe and a third tapered pipe, wherein the first tapered pipe, the second tapered pipe and the third tapered pipe are tapered, the first tapered pipe comprises two tapered sections of which openings are tapered, the first tapered pipe is installed on a baffle, a closed plate on which an overflow pipe is installed is arranged on the upper portion of the first tapered pipe, a flow guide pipe which is sleeved inside the tapered pipe is arranged on the lower portion of the first tapered pipe, the position of the flow guide pipe is lower than that of a water inlet of the hydrocyclone, the second tapered pipe is located at the lower end of the first tapered pipe, and the third tapered pipe is located at the lower end of the second tapered pipe and is arranged on the baffle. By the aid of the barrel structural form of three sections of tapered pipes and four tapered sections, the hydrocyclone can obtain acceleration continuously and obtain large centrifugal force compared with a traditional and the liquid-liquid separation is facilitated.

Description

High-effect hydrocyclone

Technical field

The utility model relates to a kind of high-effect hydrocyclone, is applicable to the suspended oil of the industries such as harbour, oil field, oil, petrochemical industry and the dirty purification of waste water of dispersed oil and processes, and belongs to liquid---and liquid separates.

Background technology

Oily water separation technique is very universal at petroleum and petrochemical industry, and separation method commonly used is settling methods, By Bubble-floating Method, filtration method, centrifugal separation etc.Hydrocyclone belongs to a kind of of centrifugation, because simple in structure, the time of staying is short, more and more be used, but owing to the various factors reason, often device design is unreasonable, causes processed complex, install and the dismounting trouble, separative efficiency is low, the import and export energy consumption is large, the problems such as thick are run in overflow.

The patent No. provides a kind of cyclone separation device for 2006201760169/200520087363 patent for this reason, the version that it utilizes baffle spiral flow channel and the diminishing Taper Pipe of opening to arrange, utilize the centrifugation principle to obtain the purpose that liquid-liquid separates, but its Taper Pipe setting of this kind version is comparatively mild, and the straight tube transition is arranged between the Taper Pipe, the acceleration that difficult acquisition is very large, centrifugal force is received impact, is unfavorable for the separation of liquid-liquid.

The utility model content

The utility model is for defects, and purpose is to provide the high-effect hydrocyclone of a kind of further raising liquid-liquid separating effect.

For achieving the above object, the technical solution adopted in the utility model is: the utility model comprises the diminishing Taper Pipe of opening, No. two Taper Pipes, No. three Taper Pipes, a described Taper Pipe comprises the diminishing two cone sections of opening and is installed on the dividing plate, its top is established shrouding, bottom that overflow pipe is installed and is established the mozzle that is set in Taper Pipe inside, and the mozzle position is lower than the cyclone water inlet; Described No. two Taper Pipes are positioned at the lower end of a Taper Pipe, and described No. three Taper Pipes are positioned at No. two Taper Pipe lower ends and are installed on the dividing plate.

Described mozzle outer peripheral face is established the screw type runner.

Described mozzle lower end outer peripheral face is the inner concave shape cambered surface.

Between a described Taper Pipe and the dividing plate, establish respectively sealing ring between No. three Taper Pipes and the dividing plate.

The utility model has the advantages that: 1) the utility model arranges the tube structure form of three sections Taper Pipes, four sections cone sections, and the acquisition acceleration that more traditional cyclone can be continuous obtains larger centrifugal force, is conducive to liquid-liquid and separates; 2) the inner concave shape cambered surface is arranged in the utility model mozzle lower end, has improved the water environment of annex, has avoided conflicting with upper mutually stream, is difficult for producing turbulent flow, has reduced overflow and has run thick phenomenon.

Description of drawings

Fig. 1 is structural representation of the present utility model.

Fig. 2 is the utility model mozzle sectional view.

Fig. 3 is the utility model mozzle front view.

Among the figure 1 for shrouding, 2 be Taper Pipe, 3 for dividing plate one, 4 for sealing ring one, 5 for overflow pipe, 6 for mozzle, 7 be No. two Taper Pipes, 8 for the tail pipe support, 9 for sealing ring two, 10 for dividing plate two, 11 be No. three Taper Pipes.

The specific embodiment

The utility model hydrocyclone is divided into three chambeies, and the centre is intake antrum, and the above is oil-discharging cavity, and the below is drain chamber.After coming water to advance intermediate cavity, advanced in the Taper Pipe by Taper Pipe 2 distributed amongst holes, produce gyrate during through mozzle 6, with reducing of the sectional area of runner, flow velocity becomes greatly gradually, produces endways and sprays, and forms High Rotation Speed, and through the contraction of following four sections cone sections, produce larger acceleration, produce centrifugation, heavier water is got rid of laterally, drain from underflow opening, lighter oil moves to the oil pocket direction.

Taper Pipe 2 of the utility model and dividing plate 1, No. three Taper Pipes 11 adopt the sealing of O RunddichtringO with dividing plate 2 10, only need advance gently each dividing plate to get final product during installation, need not bolt seal, can extract whole pipe from oil-discharging cavity during dismounting, and are very convenient.

A Taper Pipe 2 of the present utility model has two sections cone sections, and No. two Taper Pipe 7 has one section cone section, and No. three Taper Pipe 11 has one section cone section; Wherein a Taper Pipe 2 is installed on the dividing plate 1, establishes sealing ring 1 between dividing plate 1 and a Taper Pipe 2, and its top is welded with 1, number Taper Pipe 2 inside of shrouding overflow pipe 5 is housed, and overflow pipe 5 bottoms connect mozzle 6; Taper Pipe 2 bottoms connect 7, No. two Taper Pipes of No. two Taper Pipes 7 and connect union tail support 8 and dividing plate 2 10 on 11, No. three Taper Pipes 11 of No. three Taper Pipes, and 8 have seal groove on the tail pipe support, and sealing ring 29 is arranged on the seal groove.

The utility model mozzle 6 lower end outer peripheral faces are arranged to inner concave shape globoidal structure form.
