Description

Technical Field

[0001] The utility model relates to the technical field of petrochemical industry, in particular to an oil-gas separator for petrochemical products. Background Art

[0002] In the petrochemical production process, most refining production units (such as catalytic cracking, delayed coking, hydrotreating, hydrocracking, etc.) will produce oil and gas during the production process. For subsequent production and processing, the oil phase and the gas phase need to be separated in order to achieve further cutting of the oil phase and further fine separation of the gas phase.

[0003] According to a disclosed oil-gas separator for petrochemical products (publication number: CN220194387U), in the above application, two oil-gas separations can be performed to overcome the problems of single screening and poor separation effect in traditional oil-gas separators; compared with the existing centrifugal separation through a cyclone device, the operation of the cyclone device will not be affected by the stickiness of the oil; and through two separations, the best oil-gas separation effect can be ensured.

[0004] However, during the actual use of the above-mentioned equipment, the oil droplets come into contact with the mesh structure and the spikes on its surface after falling, and release the bubbles or gas inside it. However, since the positions of the mesh structure and the spikes are relatively fixed, even with multiple sets of mesh structures for separation, the gas separation effect of the oil droplets is still not ideal, and residual gas may still appear in the oil droplets. In view of this, we propose an oil-gas separator for petrochemical products. Utility Model Content

[0029] In one embodiment of the utility model, a mounting ring 81 is fixedly installed on the inner wall of the processing tank 1, a connecting rod 82 is fixedly connected to the arc-shaped inner wall of the mounting ring 81, a fixing rod 83 is fixedly connected to the center of the connecting rod 82, the fixing rod 83 penetrates and is rotatably connected to an upper sieve plate 84, the fixing rod 83 penetrates and is rotatably connected to a lower sieve plate 85, a waterproof motor 86 is fixedly installed on the bottom outer wall of the connecting rod 82, a large gear 87 is fixedly installed on the output end of the waterproof motor 86, and the large gear 87 is fixedly installed on the output end of the waterproof motor 86. A pinion 88 is fixedly mounted on the shaft, a transition gear 89 is rotatably mounted on the upper surface of the connecting rod 82, an upper annular groove 810 is provided on the lower surface of the upper sieve plate 84, a plurality of groups of protrusions 811 are fixedly mounted on the top inner wall of the upper annular groove 810, a lower annular groove 812 is provided on the upper surface of the lower sieve plate 85, a rotating rod 813 is rotatably mounted on the inner wall of the lower annular groove 812, a spring plate 814 is passed through and fixedly connected to the rotating rod 813, a volute spring 815 is sleeved on the arc-shaped outer wall of the rotating rod 813.

[0030] Furthermore, the liquid inlet pipe 2 is arranged above the atomizer 6, so that the oil-gas mixture can be input from the liquid inlet pipe 2 into the interior of the processing tank 1 and directly fall on the top of the atomizer 6, and the top of the atomizer 6 is a feed port, and the oil-liquid mixture is sprayed downward in a mist form through the atomizing nozzle 7 at the bottom of the atomizer 6. At the same time, the subdivision component 8 is arranged below the atomizer 6, so that the mist oil-liquid mixture sprayed by the atomizing nozzle 7 will fall downward on the upper screen plate 84, thereby being processed by the subdivision component 8. Specifically, an annular cavity matching the size of the mounting ring 81 is opened on the inner wall of the processing tank 1 to facilitate the positioning and installation of the mounting ring 81. At the same time, the number of connecting rods 82 is set in multiple groups, and the multiple groups of connecting rods 82 are evenly distributed in a circular array.

In addition, the upper sieve plate 84 and the lower sieve plate 85 are exactly the same size, and a number of small through holes are provided on the inner walls of the upper sieve plate 84 and the lower sieve plate 85, so that the oil-liquid mixture falling on the surface of the upper sieve plate 84 will fall along the through holes and enter the gap between the upper sieve plate 84 and the lower sieve plate 85. Through the grinding between the upper sieve plate 84 and the lower sieve plate 85, the gas inside the oil can be better separated and processed, and discharged through the exhaust pipe 3 at the top, finally realizing oil and gas separation.

[0031] In addition, the arc-shaped outer wall of the upper sieve plate 84 is provided with teeth that can mesh with the large gear 87 to realize transmission, and the small gear 88 is meshed with the transition gear 89. At the same time, the arc-shaped outer wall of the lower sieve plate 85 is provided with teeth that can mesh with the transition gear 89 to realize transmission.

At the same time, the two ends of the spiral spring 815 are respectively fixedly connected to the arc-shaped outer wall of the rotating rod 813 and the inner wall of the lower annular groove 812, so that the rotating rod 813 always has a movement tendency of reverse rotation to achieve reset when rotating. Furthermore, when the upper sieve plate 84 and the lower sieve plate 85 rotate relative to each other, the relative movement of the spring plate 814 and the protrusion 811 causes a slight vibration effect to occur between the upper sieve plate 84 and the lower sieve plate 85, so as to promote the oil-liquid mixture in the gap between the upper sieve plate 84 and the lower sieve plate 85 to obtain a better oil-gas separation effect.

[0033] In an embodiment of the utility model, an anti-residue component 9 is provided on the top of the upper screen plate 84, and the anti-residue component 9 includes an arc groove 91. The upper surface of the upper screen plate 84 is provided with an arc groove 91, and a scraper 92 is fixedly installed on the arc outer wall of the fixed rod 83.

At the same time, a plurality of tooth grooves are provided on the lower surface of the arc surface, so that when the scraper 92 and the upper screen plate 84 rotate relative to each other, the scraper 92 will scrape off the oil residue on the upper surface of the arc groove 91 to promote it to flow into the through hole opened on the inner wall of the upper screen plate 84, thereby improving the efficiency of separation of the oil-liquid mixture.

[0034] In the utility model, when in use, the oil-liquid mixture is input into the interior of the processing tank 1 through the liquid inlet pipe 2, the oil-liquid mixture drips onto the top of the atomizer 6, and is sprayed downward by the atomizing nozzle 7 after passing through the feed port at the top of the atomizer 6, so that the gas and the oil in the oil-liquid mixture are initially separated, and the gas at the separation point is discharged upward through the exhaust pipe 3, and the initially separated oil drips downward onto the upper sieve plate 84. At this time, the waterproof motor 86 is started, and the transmission of the large gear 87, the small gear 88 and the transition gear 89 is coordinated to make the upper sieve plate 84 and the lower sieve plate 85 rotate relative to each other, so as to grind and crush the oil that enters between the upper sieve plate 84 and the lower sieve plate 85 through the through hole, so as to promote the better rupture and discharge of bubbles in the oil, thereby improving the oil-gas separation effect of the device, and finally the separated oil is gathered at the bottom of the processing tank 1, and the drain valve 4 is opened to discharge it outward after a period of time.

[0035] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
