Description

PHASE SEPARATION DEVICE

The invention relates to apparatus for the separation of two-and three-phase flows and can be used in the oil, gas, chemical and other industries.

A well-known apparatus for phase separation, comprising a housing with nozzles for the input of the separated mixture and the output of the separated phases and thin-layer elements installed in the housing, (see "Modern sedimentation tanks for water treatment systems: KhM-1" Chemical and oil refining engineering, TSINTIHIMNEFTEMASH, Moscow, 1974 , p. 35-36). Oil released from the water on the bottom surface of the inclined plates floats up, and suspended solids heavier than water, settled on the surface of the inclined plates, slide down.

The disadvantages of this apparatus are its low productivity and inefficient use of the cross section of the apparatus.

Common features of the proposed device and known devices are:

- housing with nozzles for the input of the shared mixture and the output of the separated phases;

- Thin-layer elements placed in the housing.

The closest in technical superskim and the achieved result to the proposed device is a device for cleaning liquid, comprising a housing with a thin-layer module installed in it, made in the form of horizontally installed pipes having perforation in the lower and upper parts along their entire length, located with the formation of a gap along external circuit, sedimentary reservoir in the lower part of the housing, a receiving pocket, providing a supply of cleaned liquid to the pipes and a system for draining clarified liquid. The thin-layer module is made of staggered pipes and equipped with bushings that form a gap along their external circuit with hydraulic resistance exceeding the hydraulic resistance of the internal cavity of the pipes. (see RF patent No. 2135257, class V01D 21/02, publ. OB No. 24, 1999).

The disadvantages of this device are low productivity, design complexity and insufficiently effective use of the useful cross-sectional area of the apparatus.

General features of the proposed and known devices are:

a thin-layer module installed in the housing, consisting of thin-layer elements.

The technical problem is to create a device for phase separation, providing high efficiency and high productivity.

This object is achieved in that in a device for phase separation, comprising a housing with nozzles for the input of the separated mixture and the output of the separated phases, and a thin-layer module installed in the housing, consisting of thin-layer elements, the end parts of the thin-layer module are provided with rings installed in the cross section of the housing, the inner surface of the ring has a complex configuration that repeats the profile of the thin-layer module, and the outer surface of the ring is made adjacent to the inner wall of the housing.

In addition, a thin-layer module is mounted on a frame connected to the bashmaks mounted on the inner surface of the housing.

The proposed set of features provides high separation efficiency of two- and three-phase flows through the use of the entire cross-sectional area of a thin-layer module, as well as the convenience of mounting packages in a frame structure and uniform load distribution on the walls of the apparatus through the shoes.

The device for phase separation, shown in the drawing, contains a horizontal housing 1 with nozzles of the inlet 2 of the mixed flow, output 3 of the light phase and output 4 of the heavy phase. In the housing 1, a thin-layer module 5 is installed, which consists of thin-layer elements (shelves) 6 of a V-shape, assembled in packages installed with a gap relative to each other. Vertical partitions are installed between the packets with a gap relative to each packet 7. Elements (shelves) 6 are made diverging below and converging at the top and equipped with drainage holes 8 located along the entire length of the junction of two elements (shelves) 6. The end parts of the thin-layer module 5 are provided with rings 9, installed in the cross section of the device. The inner surface 10 of each ring 9 has a complex configuration that repeats the profile of the thin-layer module 5. The outer surface 11 of each ring 9 is adjacent to the inner wall of the housing 1. The thin-layer module 5 is mounted on the frame 12, which is mounted on the inner surface of the housing 1 on the shoes 13.

A device for phase separation works as follows. The mixed flow through the inlet pipe of the mixture 1 enters the chamber formed between the inlet pipe 1 and the thin-layer module 5, where there is a rough separation of the heterogeneous stream. Next, the flow enters the thin-layer module 5, where, according to the law of gravity, the heavy phase is deposited on the shelves 6. The precipitated light phase, passing through

a thin-layer module 5 is discharged through the outlet pipe 3 of the light phase, and the heavy phase flowing down the shelves 6 and along the vertical partitions 7, and then discharged through the pipe 4 of the exit of the heavy phase.
