Abstract
Description
Technical Field
[0001] This utility model relates to the field of defoamer technology, specifically to a mechanical defoaming separation and filtration device. Background Technology
[0002] The foam carried by the produced gas needs to be effectively defoamed before entering the critical equipment to avoid adverse effects such as affecting the accuracy of metering equipment and increasing the load on pumps in subsequent equipment.
[0003] Chinese patent CN116574542A discloses a high-efficiency cyclone defoaming oil-gas separation device, including a tank, which includes a medium inlet, an oil outlet, and a natural gas outlet. The inner side of the medium inlet is equipped with a cyclone defoaming component to improve the defoaming rate, and the inner side of the natural gas outlet is equipped with a wire mesh demister to defoam micro-foams. This device uses cyclone and hypergravity field for forced defoaming. However, this device is still difficult to meet the higher defoaming rate requirements of the produced gas.
[0004] Based on this, the present invention designs a mechanical defoaming separation and filtration device to solve the above problems. Utility Model Content
[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a mechanical defoaming separation and filtration device.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A mechanical defoaming separation and filtration device includes a cyclone separator;
[0008] The feed end inside the cyclone tube is equipped with multiple cyclone vanes arranged in a circumferential array; one end of the air guide pipe is fixedly connected to the inside of the cyclone tube, and the other end of the air guide pipe extends from the feed end of the cyclone tube to the outside of the cyclone tube; the discharge end of the cyclone tube is connected to a conical guide pipe.
[0009] Furthermore, the discharge end of the conical guide tube is connected to a downcomer.
[0010] Furthermore, the swirl degree of the swirl vane is 25 degrees.
[0011] Furthermore, the cone angle of the conical guide tube is between five and twenty degrees.
[0012] Furthermore, a wire mesh demister is fixedly installed at the discharge end of the downcomer.
[0013] Furthermore, the swirl vanes are made of stainless steel.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: When the medium enters the cyclone drum, the medium will swirl down along the swirl vanes in the cyclone drum. Under the action of speed and swirl, centrifugal force is generated and it enters a state of supergravity. During the swirl process, it collides with the cyclone drum to break the foam. The core of this component is the swirl angle and the feed cross-sectional area of the cyclone drum. Based on the incoming material pressure and flow rate and after a large number of tests and fluid simulation tests, the most suitable swirl angle and diameter of the cyclone drum were selected. After swirl, the liquid flows out along the conical guide pipe and the downcomer, while the gas is discharged along the gas guide pipe, realizing the defoaming and gas-liquid separation effects.

[0020] Example 1: In some embodiments, please refer to the accompanying drawings. Figure 1 A mechanical defoaming separation and filtration device, comprising a cyclone cylinder 81;
[0021] The feed end inside the cyclone cylinder 81 is equipped with multiple cyclone vanes 82 arranged in a circumferential array; one end of the air guide pipe 83 is fixedly connected to the inside of the cyclone cylinder 81, and the other end of the air guide pipe 83 extends from the feed end of the cyclone cylinder 81 to the outside of the cyclone cylinder 81; the discharge end of the cyclone cylinder 81 is connected to a conical guide pipe 84, and the discharge end of the conical guide pipe 84 is connected to a downcomer 85;
[0022] When the medium enters the cyclone separator 81, it will swirl down along the swirl vanes 82 within the separator 81. Under the action of speed and swirling, centrifugal force is generated, and the medium enters a state of hypergravity. During the swirling process, it collides with the cyclone separator 81 to break up the foam. The core of this component is the swirling angle and the feed cross-sectional area of the cyclone separator 81. Based on the incoming material pressure and flow rate, and after a large number of experiments and fluid simulation tests, the most suitable swirling angle and diameter of the cyclone separator 81 were selected. After swirling, the liquid flows out along the conical guide pipe 84 and the downcomer 85, while the gas is discharged along the gas guide pipe 83, achieving the effects of defoaming and gas-liquid separation.
[0023] The swirl tube 81, swirl vane 82, air guide tube 83, conical guide tube 84, and downcomer 85 can all be selected in different sizes according to the application requirements.
[0024] The swirl degree of the swirl vane 82 is 25 degrees;
[0025] The cone angle of the tapered guide tube 84 is between five and twenty degrees;
[0026] A wire mesh demister 86 is fixedly installed at the discharge end of the downcomer 85 to prevent the separated liquid from directly impacting the liquid surface and causing bubbles to return to the liquid.
[0027] The swirl vane 82 is made of stainless steel to enhance its corrosion resistance and impact resistance.
[0028] The downcomer 85 can be configured as an inverted cone to disperse the liquid flowing downward along its inner wall, reduce the impact force of the liquid, and multiple downcomers 85 can be connected in series.
