RU74315U1 - HYDROCYCLONE - Google Patents

Abstract

The hydrocyclone is designed to separate liquid inhomogeneous media and can find application in the oil and gas industry. The hydrocyclone contains a housing (1), the cylindrical part of which is connected to the upper (2) and lower (3) sub, between which conical sections (4, 5, 6) are placed in series, interconnected by centering rings (7), a tangentially integrated inlet pipe (8), an axial drain pipe (9) for the liquid phase and a discharge pipe (10) for solid particles. Cost reduction, increased ease of use.

Description

The utility model is intended for the separation of heterogeneous liquid media and may find application in the oil and gas industry.

A known hydrocyclone containing a cylindrical conical housing, at one end of which there is a tangential inlet pipe and an axial pipe for outputting the light phase, at the other is a sand nozzle, and an axial element for pressure equalization is installed inside the housing (RF patent No. 21211095, published on 08.27.2003, )

A hydrocyclone is also known, including a cylindrical conical housing with a tangential inlet and coaxially with the housing sand nozzles, a cover with an axial drain pipe, an annular liner under the cover with tangential channels of various sections (RF patent No. 2242289, published on December 20, 2004).

The closest adopted for the prototype is a hydrocyclone containing a cylindrical conical housing, a tangential inlet, a drain pipe for outputting a light product and an unloading outlet for outputting a heavy product (RF patent No. 2180272, publ. March 10, 2002).

A common disadvantage of the known hydrocyclones is the implementation of the housing in the form of a single monolithic structure of a cylindrical shape, which increases the cost, complicates the manufacture, transportation, installation and maintenance of the hydrocyclone.

The task to which the utility model is directed is to reduce the cost of production and increase the convenience of operating a hydrocyclone.

The technical result consists in reducing the cost and improving the convenience in the manufacture, transportation and maintenance of the hydrocyclone, due to the implementation of its collapsible design.

The technical result is achieved by the fact that in a hydrocyclone containing a housing, a tangentially integrated inlet pipe, a drain and discharge pipe, according to a utility model, the cylindrical part of the housing is connected

with upper and lower sub, between which at least three conical sections are connected in series, interconnected by centering rings.

Between the distinguishing features and the achieved technical result, there is the following causal relationship.

The design of the collapsible hydrocyclone, consisting of several parts, namely, of the body, upper and lower sub and three sections, due to their small dimensions and low metal consumption, greatly simplifies the manufacture, transportation, installation of the hydrocyclone and its maintenance, which entails a reduction in cost. .

The inventive utility model is illustrated by drawings, where in Fig.1 shows a General view of the hydrocyclone, Fig.2 is a diagram of the separation of liquid and solid phase.

The hydrocyclone is made collapsible and contains a housing 1 (Figs. 1, 2), the cylindrical part of which is connected by thread to the upper 2 and lower 3 sub, between which three conical sections 4, 5, 6 are connected in series, gradually tapering downwards. with centering rings 7, a tangentially integrated inlet pipe 8, an axial drain pipe 9 for the liquid phase and a discharge pipe 10 for solid particles (sludge) that accumulate in a special container (not shown), consisting of several (2-5) pump-compressors quarrel pipes (tubing).

The hydrocyclone operates as follows.

The processed fluid enters through the inlet, tangentially built-in 8 nozzle (figure 2) into the cylindrical part of the housing 1 and receives an intense rotational movement, in which heavy solid particles are discarded by the action of centrifugal forces to the periphery to the wall of the hydrocyclone, and the lighter liquid phase is concentrated in the center rotation of the flow and due to the reverse current enters the drain pipe 9. The sediment settling in the near-wall zone and large suspended particles moving down the wall,

fall through the discharge pipe 10 and accumulate in a special container.

Compared with the known, the claimed hydrocyclone has the following advantages:

- the possibility of manufacturing a hydrocyclone in mechanical repair shops;

- for the manufacture of parts does not require any complex equipment, they are all made on a screw-cutting machine CA 562;

- collapsible design makes it easy to maintain a hydrocyclone, facilitates its transportation and installation;

- has a low cost;

- the possibility of reusable use;

- when changing the hydrocyclone, a container with sludge rises at the same time, which eliminates the additional cost of cleaning the face.

Claims (1)

A hydrocyclone containing a housing, a tangentially integrated inlet pipe, a discharge and discharge pipe, characterized in that the cylindrical part of the housing is connected to the upper and lower sub, between which at least three conical sections are connected in series, connected by centering rings.
