The two flow blocking plates 15 are arranged at intervals in a direction perpendicular to the radial direction in which the mixed medium inlet 18 and the exhaust port 20 are installed. The spoiler 15 has an arc-shaped structure and has an arc-shaped concave surface 15a and an arc-shaped convex surface 15b, wherein the arc-shaped concave surface 15a is disposed toward the flow guiding surface 46 of the flow guiding bluff body 14, the arc-shaped convex surface 15b is disposed toward the exhaust port 20, and the specific position where the spoiler 15 is installed between the flow guiding bluff body 14 and the exhaust port 20 and the specific orientation angle of the spoiler 15 can be determined according to the actual working conditions, such as the flow rate design of the mixed medium.

More specifically, in the illustrated embodiment, the top end of the barrel 12 is provided with an end cap 48, and the end cap 48 removably covers the top end opening of the barrel 12. The top end of the flow guiding blunt body 14 is fixedly connected to the bottom of the end cap 48, and the top end of the flow blocking piece 15 is fixedly connected to the bottom of the end cap 48.

In the illustrated embodiment, the bluff body 14 is a cylindrical structure having a cross-section in the shape of a heart. The blunt flow guiding body 14 has an inner concave surface 44 extending in the circumferential direction and outer lateral surfaces 46 extending from both side edges of the inner concave surface 44 in the circumferential direction, the inner concave surface 44 is an inner concave arc-shaped curved surface, the outer lateral surfaces 46 are outer convex arc-shaped curved surfaces, and the inner concave surface 44 and the outer lateral surfaces 46 jointly form the whole lateral surface of the blunt flow guiding body 14. In the illustrated embodiment, the recessed area defined by the concave surface 44 extends along the length of the bluff body 14. The inner concave surface 44 forms a striking surface 44 of the flow guiding bluff body 14, the outer side surface 46 forms a flow guiding surface 46 of the flow guiding bluff body 14, the mixed medium inlet 18 faces the striking surface 44, and the outer side surface 46 is an arc-shaped surface and converges towards the exhaust port 20. The gas-liquid-solid mixed medium is ejected from the mixed medium inlet 18 at a high speed and is impacted on the impact surface 44, so that the gas-liquid-solid mixed medium is elastically separated. The separated liquid-solid fluid flows along the inner concave surface 44 and the outer lateral surface 46 to the inner wall of the cylinder, then flows into the cavity 26, and finally is discharged through the liquid discharge port 22 and the solid discharge port 24 respectively. During this process, some slurry and attachments may adhere to the inner and

outer surfaces

44, 46 of the bluff body 14, and the vibrator 16 vibrates the bluff body 14 at high frequency to cause the slurry and attachments to fall into the cavity 26, thereby cleaning the walls of the bluff body 14. The separated gas is guided by the flow guide surface 46 to flow towards the exhaust port 20, and a part of the gas enters the cavity 26, and the pressure in the cavity rises due to the gradual increase of the liquid-solid fluid in the cavity 26, so that the gas retained in the cavity 26 is finally extruded to the exhaust port 20 to be exhausted.

After the gas-liquid-solid mixed medium ejected from the mixed medium inlet 18 hits the guiding blunt body 14, the ejection direction of the fluid is forcibly changed, and in the process, part of the liquid, the solid and the mixture thereof are driven to the spoiler 15 by the high-speed gas flow, for example, the high-speed gas flow guided to flow along the guiding surface 46 of the guiding blunt body 14, and is blocked by the arc-shaped concave surface 15a of the spoiler 15, so that the flow field is changed accordingly. The liquid, solid and their mixture will adhere to the flow blocking plate 15, and a part will automatically fall into the cavity 26 due to its own weight, and another part will vibrate through the vibrator 16 to drive the end cap 48 to vibrate, and further drive the flow blocking plate 15 to vibrate and fall off. The gas flows along the arc-shaped convex surface 15b of the spoiler 15 to the exhaust port 20 to be exhausted. Therefore, the baffle 15 has a secondary separation function, thereby improving the separation efficiency and preventing liquid and solid from entering the exhaust port.

In the illustrated embodiment, the baffle bluff body 14 is mirror symmetric about a mid-axis tangent to the inner concave surface 44 and the outer lateral surface 46, which coincides with a diametric plane of the barrel 12, and the mixed media inlet 18 and the exhaust port 20 are located on opposite sides of the diametric plane of the barrel 12 such that the mixed media inlet 18 faces the inner concave surface 44 and the exhaust port 20 faces the baffle surface 46.

The vibrator 16 is vertically connected in the flow guide blunt body 14 at the middle position of the end cover 48, and an eccentric motor is arranged in the vibrator 16, and can be used for vibrating slurry and attachments adhered to the wall surface of the flow guide blunt body 14, and can also drive the flow blocking sheet 15 to vibrate so that the slurry and the attachments adhered to the wall surface of the flow blocking sheet 15 fall off, thereby improving the separation efficiency.

Because the blunt body 14 and the spoiler 15 are hit sides and are easily damaged, in this embodiment, the blunt body 14 and the spoiler 15 are detachably mounted in the barrel 12, so as to facilitate detachment, maintenance and replacement. The vibrator 16 is also configured to be removably attached to the inside of the bluff body 14 for ease of maintenance.

It should be understood that, in the above embodiments, the shape structure of the flow guiding blunt body and the arrangement of the striking surface and the flow guiding surface thereof are only one embodiment of the present invention, and in other embodiments, the flow guiding blunt body may be designed in other shapes, and the striking surface and the flow guiding surface thereof may be designed in other manners, as long as the conditions that the mixed medium inlet faces the striking surface, and the flow guiding surface converges to the exhaust port are satisfied, and the present invention is not limited thereto.

It should also be understood that, in the above embodiments, the shape and structure of the flow blocking sheets and the number and arrangement of the flow blocking sheets are only one embodiment of the present invention, and in other embodiments, the flow blocking sheets may be arranged in other shapes, numbers and arrangements, which is not limited by the present invention.

In the oil exploitation production chain, the grid type elastic separation device can be used as a front-end filtering device and can timely separate and collect gas-liquid-solid mixed media from a drilled well.

A grid-type resilient separating device may also be used in conjunction with fine filtration equipment, for example in conjunction with an inertial separator. The refined gas can be directly used or stored. Because the grid type elastic separation device filters most large particles and slurry, the problems that follow-up equipment is damaged by particle impact and parts are frequently replaced are solved, the service life of the inertial separator is greatly prolonged, the maintenance frequency of the follow-up equipment is reduced, and the guarantee is provided for the follow-up equipment.
