[0006] (II) Technical Solution

[0007] To achieve the above objectives, the main technical solutions adopted by this utility model include:

[0008] In a first aspect, the present invention provides a device for multiphase separation, comprising a rotating component and a stationary component;

[0009] The rotating component includes a rotating shaft, a rotating cavity, circumferential blades, a retention chamber, and a guide plate. The rotating cavity is shaped like a horizontal double-pointed gyroscope. The rotating shaft is horizontally positioned in the middle of the rotating cavity. The circumferential blades are arranged around the rotating shaft. A retention chamber is set at the inner circular edge of the rotating cavity to store liquid / solid. A guide plate is set inside the rotating cavity to change the flow direction of gas, solid, and liquid.

[0010] The stationary component includes a housing, a mixed fluid inlet, a gas outlet, and a liquid / solid outlet. The housing is arranged around the rotating cavity. The mixed fluid inlet and gas outlet are respectively provided at the left and right ends of the housing, and the liquid / solid outlet is provided at the upper and lower ends of the housing.

[0011] The device for multiphase separation proposed in this embodiment uses a rotating shaft to drive circumferential blades to rotate and a guide plate is installed inside the device to separate the mixed fluid from the gas and solid / liquid under the action of centrifugal force, effectively solving the technical problems of large size, low efficiency and poor separation effect of the separation equipment in the prior art.

[0012] Preferably, the device further includes a gas guide pipe disposed on the inner wall of the rotating cavity, so that the return gas flows to the gas outlet.

[0014] Preferably, the guide vane includes a first guide vane, a second guide vane, and a third guide vane;

[0015] The first guide plate is circular and is vertically mounted on the rotating shaft to change the direction of movement of the mixed fluid;

[0016] The second guide plate consists of several inclined plates, which are installed along the outer edge of the first guide plate;

In this document, directional terms such as "upper," "lower," etc., are used interchangeably with other directional terms. Figure 1 The orientation is used as a reference.

[0041] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0042] This utility model discloses a device for multiphase separation, comprising a rotating component and a stationary component. The rotating component includes a rotating shaft, a rotating cavity, circumferential blades, a retention chamber, and a guide plate. The rotating cavity is generally shaped like a horizontally placed double-pointed gyroscope. The rotating shaft is horizontally positioned in the middle of the rotating cavity, and the circumferential blades are arranged around the rotating shaft. A retention chamber is provided at the inner circular edge of the rotating cavity to store liquid / solid. A guide plate is provided inside the rotating cavity to change the flow direction of gas, solid, and liquid. The stationary component includes a shell, a mixed fluid inlet, a gas outlet, and a liquid / solid outlet. The shell is arranged around the rotating cavity, with a mixed fluid inlet and a gas outlet at the left and right ends of the shell, respectively, and a liquid / solid outlet at the upper and lower ends of the shell.

[0043] This utility model provides a device for multiphase separation, which solves the technical problems of large separation equipment, slow separation process, low efficiency and poor separation effect in the prior art.

[0044] like Figure 1-2 As shown, the device for multiphase separation includes a rotating shaft 1, a rotating chamber 2, circumferential blades 3, a retention chamber 4, a guide plate, a housing 6, a centrifugal sealing strip 7, a gas guide pipe 8, a mixed fluid inlet 91, a gas outlet 92, a liquid / solid outlet 93, and a flow regulating valve 10.

[0045] The rotating cavity 2 is shaped like a horizontal double-pointed gyroscope. The rotating shaft 1 is horizontally positioned in the middle of the rotating cavity. The circumferential blades 3 are evenly spaced around the rotating shaft 1. There are 12 circumferential blades 3. The inner circular edge of the rotating cavity 2 is provided with a retention chamber 4 to store liquid / solid. The rotating cavity is provided with a guide plate to change the flow direction of gas, solid and liquid.

[0046] The guide vanes include: a first guide vane 51, a second guide vane 52, and a third guide vane 52. The first guide vane 51 is circular and is vertically arranged on the rotating shaft 1. It changes the direction of movement of the mixed fluid. The mixed fluid enters from the mixed fluid inlet 91 and moves laterally along the rotating shaft 1. Under the rotational separation action of the circumferential blades 3, the gas and liquid / solid undergo preliminary separation. The separated liquid / solid reaches the first guide vane 51, which changes the direction of movement of the separated liquid / solid to longitudinal. The second guide plate 52 consists of four sets of inclined plates, with an angle of 30-60° between it and the rotating shaft. It is fixed along the outer edge of the first guide plate 51 and the second guide plates 52 are concentrically arranged. The second guide plates 52 further guide the longitudinally moving liquid / solid towards the retention chamber 4. The third guide plate 53 is installed at 1 / 2-2 / 3 of the distance between the retention chamber 4 and the rotating shaft 1, with an angle of 30-60° between it and the rotating shaft 1. It gathers the liquid / solid, allowing the gas to flow back. The gas guide pipe 8 is located on the inner wall of the rotating chamber 2, allowing the returning gas to flow more smoothly from near the third guide plate 53 to the gas outlet 92.

[0047] The outer casing 6 is arranged around the rotating cavity 2. A mixed fluid inlet 91 and a gas outlet 92 are respectively provided at the left and right ends of the outer casing 6. A liquid / solid outlet 93 is respectively provided at the upper and lower ends of the outer casing 6. A flow regulating valve 10 is installed on the liquid / solid outlet 93 to control the outflow of liquid / solid.

[0048] Since the density of liquid / solid is about 1000 times that of gas and its inertia is greater, it experiences a large centrifugal force in the high-speed rotating chamber 2. Therefore, liquid / solid will be thrown into the retention chamber 4 along the circumference. Gas has a low density and experiences less centrifugal force, so it is easier to accumulate in a position closer to the rotating shaft 1. Under the action of pressure difference, gas will flow towards gas outlet 92.

[0049] A centrifugal sealing strip 7 is provided between the rotating cavity 2 and the outer shell 6. The centrifugal sealing strip 7 is a blade-shaped sealing component. Multiple centrifugal sealing strips 7 are arranged circumferentially around the two liquid / solid outlets 93. The centrifugal sealing strip 7 is welded to the rotating cavity 2 and has a width of 0.5 mm (the distance between the rotating cavity 2 and the outer shell 6 is 1 mm). The length of the centrifugal sealing strip 7 is 1 / 3 to 1 / 2 of the total length of the channel formed by the rotating cavity 2 and the outer shell 6.

[0050] The principle behind the centrifugal sealing strip 7 preventing gas leakage is as follows: the gas pressure leaking from the retention chamber 4 is high, while the pressure leaking from the gas outlet 92 is low. The centrifugal sealing strip 7 increases the gas velocity below (gas outlet 92), creating a greater upward centrifugal force that counteracts the gas pressure above the blades of the centrifugal sealing strip 7, thereby reducing the pressure difference between the two ends of the blades of the centrifugal sealing strip 7 and reducing the amount of leakage from the retention chamber 4 to the gas outlet 92.

[0051] In one embodiment, the operation of the device for multiphase separation includes:

[0052] S1: The mixture of gas and solid / liquid enters the separation device through the mixed fluid inlet 91. Under the separation action of the circumferential blades 3, the gas and solid / liquid are initially separated. The separated solid / liquid enters the rotating chamber 2, and the gas is discharged from the gas outlet 92.

[0053] S2: The solid / liquid that has completed the primary separation moves in the direction of the retention chamber 4 under the guidance of the first guide plate 51. The gas flows to the gas outlet 92 through the gas guide pipe 8, and the solid / liquid flows to the liquid / solid outlet 93 through the third guide plate 53.
