Description

Technical Field

[0001] The utility model relates to the technical field of cyclone separation, in particular to a natural gas cyclone separation device. Background Art

[0002] Natural gas extracted from the wellhead is a mixture containing impurities such as water vapor, sulfides, and carbon dioxide. During pipeline transportation, the water vapor in the mixture cools and condenses, causing liquid water to be present in the natural gas. The presence of liquid water not only reduces the effective transportation capacity of the natural gas pipeline but, in severe cases, can also form hydrates, causing pipeline blockages and potentially major accidents. Therefore, wet natural gas must be dehydrated.

[0003] When using the existing natural gas cyclone separation device, the natural gas often enters the device at an inappropriate angle, resulting in a slow intensity and speed of natural gas entering the device, which in turn leads to poor separation effect; therefore, it does not meet the existing needs. In this regard, we propose a natural gas cyclone separation device. Utility Model Content

[0004] The purpose of the present utility model is to provide a natural gas cyclone separation device to solve the problems of the natural gas cyclone separation device proposed in the above background art, which is often encountered when using the natural gas cyclone separation device, due to the unsuitable angle of natural gas entering the interior of the device, resulting in slow strength and speed of natural gas entering the device, thereby resulting in poor separation effect.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a natural gas cyclone separation device, comprising an inlet pipe, a direct current pipe fixedly mounted on the rear side of the inlet pipe, a cyclone pipe fixedly mounted on the rear side of the direct current pipe, a separation pipe fixedly mounted on the rear side of the cyclone pipe, a diffuser pipe movably mounted on the rear side of the separation pipe, a cyclone ball movably mounted inside the direct current pipe, a movable rod fixedly mounted on the rear side of the cyclone ball, an arc-shaped protrusion fixedly mounted on the outer surface of the movable rod, and the arc-shaped protrusion being located at the opening position of the cyclone tube.

[0006] Preferably, a spiral blade is fixedly mounted on the outer surface of the swirl ball, the movable rod is slidably inserted into the interior of the diffuser tube, and the rear side of the movable rod is connected to an L-shaped rod via bolts.

[0007] Preferably, a limit plate is fixedly installed at the end of the L-shaped rod, and a plurality of limit holes are provided on the surface of the limit plate. A fixed plate is fixedly installed on the rear surface of the diffuser tube, and a limit pin is movably installed on the top of the fixed plate. A spring groove is provided on the top surface of the fixed plate, and the limit pin is slidably inserted into the interior of the spring groove. A limit block is fixedly installed on the bottom end of the limit pin, and the limit block is movably inserted into the interior of the limit hole. A compression spring is movably installed between the limit block and the interior of the spring groove, and the limit pin is movably inserted into the interior of the compression spring.

[0008] Preferably, a bracket is fixedly installed inside the diffuser tube, the movable rod movably passes through the center position of the bracket, and a plurality of air outlets are provided on the surface of the bracket.

[0009] Preferably, a liquid outlet is fixedly mounted on the bottom end of the separation tube, and one end of the diffuser tube is movably inserted into the interior of the separation tube.

[0010] Preferably, the cross-section of the inner wall surface of the inlet pipe is in the shape of a Witosinski curve, and the angle between the inner wall of the swirl tube and the arc-shaped protrusion is fifteen to thirty degrees.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. The utility model provides an inlet pipe so that when the device is in use, the surface of the inner wall of the inlet pipe presents a Witosinski curve, so that the natural gas can enter the cyclone separator more evenly and smoothly, reducing the flow field disturbance at the inlet, thereby improving the separation efficiency;

[0013] 2. The present invention utilizes the cooperation of the L-shaped rod and the movable rod. When the device is in use, the L-shaped rod can be pulled to drive the movable rod and the swirl ball to move inside the direct current tube, thereby driving the arc-shaped protrusion to move inside the swirl tube, thereby increasing or decreasing the distance between the arc-shaped protrusion and the inner wall of the swirl tube, thereby adjusting the angle between the direct current tube and the interior of the separation tube. The device can adjust the appropriate angle according to specific working conditions, so that it can better guide the airflow to form a stable swirl in the swirl chamber, which helps to improve the swirl intensity and separation effect of natural gas.

[0014] 3. The utility model cooperates with the limiting block and the limiting hole so that when the device moves the position of the arc-shaped protrusion, the limiting pin can be pulled outward first, so that the limiting pin drives the spring groove to be pulled out from the inside of the limiting hole. At this time, the L-shaped rod is moved to align the remaining limiting holes with the positions of the spring grooves. Then the limiting pin is released, and the spring groove is ejected by the elastic potential energy of the compressed spring and inserted into the inside of the limiting hole, thereby fixing the movable rod to prevent the airflow from entering and pushing the swirl ball to move. At the same time, the distance between the arc-shaped protrusion and the inner wall of the swirl tube can be fixed to prevent the arc-shaped protrusion from completely blocking the swirl tube, so that the airflow can pass through the inside of the device stably.

[0025] Through the cooperation of the limit block 19 and the limit hole 16, when the device moves the position of the arc-shaped protrusion 10, the limit pin 17 can be pulled outward first, so that the limit pin 17 drives the spring groove 18 to be pulled out from the inside of the limit hole 16.

[0030] And by pulling the L-shaped rod 12, the L-shaped rod 12 drives the movable rod 11 and the swirl ball 8 to move inside the direct current pipe 2, and then drives the arc-shaped protrusion 10 to move inside the swirl pipe 3, so that the distance between the arc-shaped protrusion 10 and the inner wall of the swirl pipe 3 increases or decreases, and then adjusts the angle between the direct current pipe 2 and the interior of the separation pipe 4, so that the device can adjust the appropriate angle according to the specific working conditions, so that it can guide the airflow to better form a stable swirl in the swirl chamber, which helps to improve the swirl intensity and separation effect of natural gas.

[0031] When adjusting the angle between the arc-shaped protrusion 10 and the swirl tube 3, the limit pin 17 can be pulled outward first, so that the limit pin 17 drives the spring groove 18 to be pulled out from the inside of the limit hole 16.
