Description

Technical Field

[0001] The utility model relates to the technical field of gas-liquid-powder separation equipment, in particular to a gas-liquid-powder separation device. Background Technique

[0002] In gas field surface engineering, the gas well produced fluid is a mixed fluid composed of gas, liquid, sand, dust, foam, etc. At the same time, the mixed fluid is also mixed with sediment. The gas-liquid-powder separator is a widely used gas, liquid, sand, dust, and foam separation equipment. However, in the specific use process, it is necessary to support means for removing sediment and dust regularly or irregularly, and then perform gravity sedimentation to remove liquid (oil and water).

[0003] Chinese Patent CN200520079440.7 discloses a novel oil-gas-water-sand four-phase separation device. The housing of the device adopts a cylindrical horizontal structure. The interior of the housing is sequentially divided into a sedimentation chamber, an oil buffer chamber, and a water buffer chamber by an oil buffer chamber partition plate and a water buffer chamber partition plate arranged along its front-rear direction. The following limitations exist in the specific implementation process of this prior art. When implementing this separation device, the mixed fluid enters the sedimentation chamber from the liquid inlet of the gas-liquid pre-separator for preliminary separation. The separated gas is discharged from the exhaust port of the secondary demister. The gas outlet often carries a certain amount of dust and foam, and separate dust removal and defoaming equipment needs to be set up, increasing the length of the gas treatment process.

[0004] In the publicly disclosed Chinese patent application, the publication number is: CN204411781U, and the patent name is: A three-phase separator. In the specific implementation process of this prior art, the oil-gas-water medium enters the interior of the separator cylinder from the inlet. After the gas and liquid are pre-separated by the inlet energy separator, they fall onto the partition plate. The partition plate is provided with a first weir plate, a second weir plate, and a third weir plate. The first weir plate and the third weir plate form a sedimentation chamber in the upper shell pass. After the oil-water mixture is separated at the first stage in the upper shell pass, the water phase is introduced into the water layer in the lower shell pass through a water guide pipe. The oil phase in the upper shell pass flows over the second weir plate into the oil chamber between the first weir plate and the second weir plate, and is introduced into the oil layer in the lower shell pass through an oil guide pipe. The length of the water guide pipe extending downward is below the interface between the water layer and the oil layer in the lower shell pass, and the length of the oil guide pipe extending downward is above the interface between the water layer and the oil layer in the lower shell pass to ensure that the oil phase and the water phase introduced into the lower shell pass will not be remixed. By adjusting the control valves of the oil guide pipe, the water guide pipe, the oil outlet, and the water outlet, the required interface position between the water layer and the oil layer can be ensured, and it can be observed through a liquid level gauge. A coalescing packing device is provided in each shell pass for separating oil, gas, and water. There are certain limitations in the specific implementation process of this prior art. Among them, the gas separated from the oil, gas, and water is directly discharged into the air. Since there is dust in the gas, the dust entering the air seriously affects the surrounding air quality and is not conducive to environmental protection.

[0005] In summary, the problems existing in the prior art are as follows: First, during the gas-liquid-sand separation process, a separate dust removal device is required to perform dust removal operations on the discharged air; Second, the gas after three-phase separation is discharged into the atmosphere without dust removal operations, seriously affecting air quality. To solve the problems existing in the above prior art, this case is specifically proposed to solve them. Summary of the Invention
