fig. 2 is a cross-sectional view of the bottom structure of the present invention;
the attached drawings indicate the following:
in the figure: 1. a barrel; 2. a feed inlet; 3. a liquid discharge pipe; 4. a cylinder; 5. a liquid discharge port; 6. a sand discharge port; 7. a separator; 8. a flow guiding cone; 9. a drain hole; 10. a wire mesh mist trap; 11. a pressure test port; 12. and (7) an exhaust port.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in figure 1, the gas-liquid-solid three-phase separator comprises a cylinder body, a separating body, a feeding hole, an exhaust hole, a sand discharge hole, a liquid discharge pipe and a wire mesh mist catcher, wherein the feeding hole, the exhaust hole, the liquid discharge hole and the sand discharge hole are all arranged on the cylinder body.
The separator is composed of a cylinder and a diversion cone, wherein the surface of the cylinder arranged at the lower part of the diversion cone is a spiral flow passage which is beneficial to liquid discharge, and the surface of the diversion cone is provided with four liquid discharge holes which are communicated with a liquid discharge pipe arranged in the diversion cone.
A sand discharge port is formed in one side of the cylinder body, so that separated silt is prevented from blocking the cylinder body, and a wire mesh mist catcher is arranged inside the cylinder body and below the air exhaust port.
And pressure test ports are arranged at the top of the cylinder body and below the exhaust port.
Gas-liquid-solid mixture extracted from hydrate reservoir enters into the cylinder body from the tangential feed inlet, and generates high-speed movement vortex under the action of pressure and centrifugal force. Because the flow guiding cone in the cylinder is in a cone-shaped structure, a part of liquid attached to the surface of the flow guiding cone in the rotating process enters the liquid discharge pipe through the liquid discharge hole and is discharged from the liquid discharge port, the other part of liquid which cannot enter the liquid discharge hole and is positioned below the liquid discharge hole is settled on the cylinder under the action of gravity, starts to swirl in the spiral flow channel on the surface of the cylinder and is finally discharged from the liquid discharge pipe. Meanwhile, under the action of centrifugal force, the lightest gas phase of the gas phase, the liquid phase and the solid phase is firstly separated, and the enriched gas rises to the wire mesh mist catcher and is discharged from a top exhaust port; the mixed medium continues to carry out rotary separation in the descending process, and the solid phase gradually moves to the side wall and is discharged out of the cyclone through the lateral sand discharge port under the action of centrifugal force.
The separated gas is dried after a part of free water is removed by the wire mesh mist catcher, enters the upper space of the cylinder body and leaves the cylinder body through the exhaust port.
The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
