Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail below with reference to the accompanying drawings, but embodiments of the present invention are not limited thereto.

Referring to fig. 1, the horizontal separator integrated with the desander comprises a desander 11, a horizontal separator 1, a liquid level meter 7, a sand separation baffle 6, a gas outlet pipeline 12 and a sand discharge pipeline 8.

Specifically, the desander 11 is installed on the side wall of the tank body of the horizontal separator 1 by welding or bolt connection, the desander 11 is provided with the air inlet 2, the air outlet pipeline 12 is connected between the desander 11 and the horizontal separator 1, and the tail end of the air outlet pipeline 12 is connected to the top of the first end (namely, the left end in fig. 1) of the horizontal separator 1. The top of the second end (i.e. the left end in fig. 1) of the horizontal separator 1 is provided with an air outlet, so that the air from the desander 11 enters from the top of the horizontal separator 1. The bottom of the first end of the horizontal separator 1 is provided with a sand discharge port 4, and the bottom of the second end of the horizontal separator 1 is provided with a water discharge port 5. The sand separation baffle 6 is vertically arranged in the middle of the inside of the horizontal separator 1, so that the horizontal separator 1 is divided into a left chamber and a right chamber, and an airflow channel is arranged between the top of the sand separation baffle 6 and the horizontal separator 1. A level gauge 7 is mounted at a first end of the horizontal separator 1. The one end of sand discharge pipeline 8 is connected in sand discharge mouth 4 department, and is provided with electrical control valve 9 on the sand discharge pipeline 8, and level gauge 7 and electrical control valve 9 electricity are connected to realize the linkage of level gauge 7 and electrical control valve 9.

Specifically, the desander 11 may be a cyclone desander or a filter desander.

The sand discharge pipeline 8 is also provided with a choke valve 10, and the electric regulating valve 9 is positioned between the sand discharge port 4 and the choke valve 10. Because the electric regulating valve 9 is not wear-resistant, the electric regulating valve cannot be in a throttling state for a long time, the throttling is mainly realized through the oil nozzle valve 10, the flow of the sand-containing water is controlled by replacing the proper oil nozzle valve 10, and the oil nozzle valve 10 is the prior art.

The principle of the utility model is as follows: the natural gas that is mingled with the sand grain gets into desander 11 from air inlet 2, the natural gas through the desander 11 degritting can not remove the sand grain completely, the natural gas gets into horizontal separator 1, because the existence of separating sand baffle 6, the sand grain is concentrated in separating the left cavity of sand baffle 6, and subside in the left cavity and have water, the sand grain is more easily got rid of under the circumstances that has water, through the linkage of level gauge 7 and electrical control valve 9, the liquid level of adjusting the left cavity is not less than critical liquid level. When the water amount in the left chamber of the liquid level is too large, the overflowed water enters the right chamber from the left chamber and is discharged through the water outlet, and when the liquid level is reduced to the critical liquid level, the electric regulating valve 9 is closed. Because water is always in the left chamber, sand grains are always in motion, the sand grains are loosened, and the sand grains are prevented from being hard to block the sand discharge pipe opening due to long-time deposition, so that continuous sand discharge and water discharge are realized.

The air current gets into the chamber of sand screen 6 right side through the air current passageway between sand screen 6 and the horizontal separator 1 top, and the gas-liquid separates here, and gas is gone out through gas outlet 3, and liquid collects and subsides the back and discharges from outlet 5.

The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
