Description

Technical Field

[0001] The utility model relates to the technical field of oil and natural gas processing, in particular to a three-phase multi-stage separator for oil and natural gas processing. Background Art

[0002] Three-phase separators are mostly used in upflow anaerobic sludge bed reactors in biological sewage treatment to separate digestion gas, digestion liquid and sludge particles. The three-phase separator is named because the substances finally separated by the three-phase separator are three different forms of substances: solid, liquid and gas. The three-phase separator is widely used in oil extraction. The newly extracted oil may be mixed with groundwater, solid particles and underground natural gas, which needs to be processed. The three-phase separator has a good effect in isolating and treating oil, water and gas, so it is widely used. When the existing three-phase multi-stage separator for oil and gas processing is in use, the oil enters through the liquid inlet pipe at a too fast speed, resulting in a large impact force, which is easy to affect the subsequent oil-water separation. Therefore, we propose a three-phase multi-stage separator for oil and gas processing. Utility Model Content

A first force plate 401 is provided at the bottom of the slider 43, and a fixed plate 46 is provided on the right side of the bottom of the top plate 40. A sleeve 45 is provided on the left side wall of the fixed plate 46, and a movable plate 49 is slidably connected in the sleeve 45. A buffer spring 48 is provided on the right side wall of the movable plate 49, one end of the buffer spring 48 is connected to the right side wall of the sleeve 45, and a buffer rod 400 is provided on the left side wall of the movable plate 49. One end of the buffer rod 400 penetrates the left side wall of the sleeve 45 and is connected to the right side wall of the first force plate 401. A second buffer assembly 5 is provided on the left side wall of the first force plate 401, and two groups of sliding rods 47 are movably penetrated on the right side wall of the fixed plate 46.

Under the action of the sliding rod 47, the movement of the first force plate 401 is more stable.

[0017] See also Figure 3The second buffer component 5 includes a sliding groove 52 provided on the left side wall of the first force-bearing plate 401, a mounting rod 53 is provided in the sliding groove 52, two ends of the mounting rod 53 are respectively connected to the front and rear side walls in the sliding groove 52, two groups of sliding blocks 54 are sleeved on the outer wall of the mounting rod 53, and a return spring 55 is sleeved on the outer wall of the mounting rod 53.

[0018] Working principle: When a three-phase multi-stage separator is needed to separate the oil, gas and water phases of petroleum and natural gas, the impact force is relatively large when the oil enters the three-phase multi-stage separator through the liquid inlet pipe 3. The oil will impact the second force plate 50, and the buffer hole 51 can disperse the oil. The second force plate 50 will rotate, and the second force plate 50 will drive the sliding block 54 to move on the outer wall of the mounting rod 53. The sliding block 54 can stretch the reset spring 55, thereby playing a buffering role. At the same time, the first force plate 401 will drive the slider 43 to squeeze the spring 44, and the first force plate 401 will drive the buffer rod 400 and the movable plate 49 to squeeze the buffer spring 48, which can further improve the buffering effect, slow down the speed at which the oil enters, and avoid the situation where the impact force is large and affects the subsequent oil-water separation.
