a cylinder 10;
the lower clapboard 21 and the upper clapboard 22 are arranged in the cylinder body from bottom to top, and divide the space in the cylinder body from bottom to top into: liquid storage zone ZLMiddle zone ZMGas buffer zone ZG；

Referring to fig. 1, in the embodiment, the cylinder 10 is a cylinder with a central axis perpendicular to a horizontal plane, but the invention is not limited thereto, and any cylinder, whether a cylinder, a regular polygon cylinder, or a cylinder with an irregular cross section, disposed vertically is within the scope of the invention.
In order to ensure the safe and reliable arrangement of the cylinder, the supporting legs 11 are arranged below the cylinder. It should be noted that the legs of the barrel of the present invention can have various forms as long as the barrel is substantially vertical, and are not limited to the leg form in the present embodiment.
A lower clapboard 21 and an upper clapboard 22 are arranged in the cylinder body from bottom to top, and both are horizontally arranged, so that the space in the cylinder is divided into: liquid storage zone ZLMiddle zone ZMGas bufferZone ZG. The sizes of the three regions can be determined according to the specific situation of the miscible medium. If the content of the gas phase medium in the mixed phase medium is higher, the volume of the gas buffer zone can be properly increased. If the content of the liquid-phase medium in the mixed-phase medium is large, the volume of the liquid storage region can be increased appropriately.
A mixed phase medium inlet O is arranged on the cylinder body outside the middle areain. The gas-phase medium outlet O is formed because the gas-phase medium has low density and is gathered to a high positionG-outPreferably at the topmost end of the gas buffer region. And the part except the gas phase medium in the mixed phase medium contains most of the liquid phase medium and a small part of the solid phase medium. The solid phase medium is mainly sand and stone soil, has high density and generally sinks below the liquid phase medium. Therefore, in order to prevent the solid phase medium from blocking the pipe, it is preferable to be in the liquid storage region ZLThe bottom of the sewage tank is provided with a sewage outlet OD-outA liquid phase medium outlet O is arranged at a position higher than the preset distance of the sewage draining outletL-out. The height of the liquid phase medium outlet can be adjusted according to needs, and is preferably 1/5-1/4 of the height of the liquid storage area.

The control device is used for:
firstly, controlling the state of a drainage pump connected to a liquid-phase medium outlet according to liquid level information of a liquid storage area acquired by a liquid level meter;
specifically, when the liquid level is higher than the preset high liquid level, the control device sends an instruction to start the drainage pump to drain the liquid in the liquid storage area. When the liquid level is reduced to a preset low liquid level, the control device sends an instruction to stop the operation of the drainage pump.
Controlling the state of a valve connected to the inlet of the mixed phase medium according to the pressure information of the middle area acquired by the pressure gauge.
In particular, when the pressure is higher than a preset pressure, the control device gives a command to close the valve at the inlet of the miscible medium, so as to protect the separator from overpressure.
An inlet baffle 23 is arranged in the middle area opposite to the inlet of the mixed phase medium. The inlet baffle 23 is fixed on the upper baffle plate, and the radial distance between the inlet baffle and the miscible medium is 1.5-3 times of the pipe diameter of the miscible medium inlet; the distance extending to the periphery of the device is 2-3 times of the pipe diameter of the miscible medium inlet by taking the position facing the center of the miscible medium inlet as the center.
After the miscible medium is flushed into from the miscible medium inlet, liquid drops in the miscible medium can collide with the inlet baffle plate 23 firstly and bend, and collide with each other to gather into large liquid drops to be separated out in the middle area, so that the separation pressure of the cyclone casing pipe is reduced, and the gas-liquid separation efficiency of the cyclone separator is improved.
It should be understood by those skilled in the art that the fixing manner, area, radial distance from the inlet of the miscible medium, etc. of the inlet baffle can be adjusted as required, and it is within the scope of the present invention as long as the inlet baffle can block the miscible medium entering from the inlet of the miscible medium, bend and collide the miscible medium, so that the small droplet particles can enter the intermediate zone after being aggregated into large droplet particles.
And a liquid guide hole 24 is formed in one side of the lower partition plate, which is far away from the mixed phase medium inlet, and when the liquid content of the mixed phase medium is high, the liquid phase medium is firstly separated in the middle area and is guided into the liquid storage area through the liquid guide hole 24. The liquid guide hole 24 is positioned on one side far away from the mixed-phase medium inlet, so that the mixed-phase medium is prevented from flowing out of the liquid guide hole too fast, and the gas-liquid separation effect is improved in the flowing process of the liquid guide hole 24.

The swirl vanes 33 are arranged in the medium descending channel, so that the gas-liquid mixed phase medium obtains a larger tangential speed in the falling process, a larger centrifugal force is generated, the liquid is thrown out towards the outer side, and the gas is converged towards the inner side, so that the mixed phase medium is easier to separate. Meanwhile, the spiral structure of the swirl vane has simple structure and is easy to process and manufacture.
As mentioned above, this embodiment includes 5 sets of swirl sleeves. The 5 groups of cyclone sleeves are all independent of the cylinder body, so that the problem of poor separation effect caused by increasing the processing capacity of the mixed phase medium by simply increasing the diameter of the cylinder body is solved, the design and processing efficiency of the separator is improved, and the processing difficulty is reduced.
