Description

Technical Field

[0001] This utility model relates to the field of oil and gas recovery technology, specifically to a three-stage oil and gas recovery device for oil depots. Background Technology

[0002] As a core node for oil and gas storage and transportation, oil depots are a significant source of air pollution due to their volatile organic compound (VOC) emissions. Tertiary oil and gas recovery equipment can significantly reduce VOC emissions by deeply treating residual oil and gas, helping oil depots meet environmental regulatory requirements and avoid the risk of fines or business suspension due to excessive emissions.

[0003] In existing equipment, before condensing oil and gas into liquid, an adsorbent is usually used to adsorb the oil and gas. Then, the adsorbed oil and gas is heated by a heater so that it can enter the condenser through a pipeline. The condenser is then started to lower the temperature of the oil and gas, so that it can be condensed into liquid and then recycled.

[0004] However, existing devices typically install the inlet pipe on one side of the adsorbent. After the oil and gas enter the filter barrel, they cannot be uniformly adsorbed by the adsorbent. This may result in the adsorbent not being fully utilized, leading to a reduction in the adsorbent's effectiveness and a significant decrease in the oil and gas recovery efficiency. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a three-stage oil and gas recovery device for oil depots, which can solve the existing problems.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] An oil depot tertiary oil and gas recovery device includes: a housing, a condenser mounted on the housing, a filter barrel mounted on the condenser, a heater mounted on the filter barrel, a liquid storage tank mounted on the condenser, and an air inlet pipe mounted on the filter barrel; it also includes: a filter assembly mounted on the filter barrel, the filter assembly including a drive motor mounted on the filter barrel, a main shaft mounted on the output end of the drive motor, an activated carbon filter layer mounted on the main shaft, and a filter screen mounted on the activated carbon filter layer; a cleaning assembly mounted on the filter barrel, the cleaning assembly including a connecting block mounted on the filter barrel, a spring column mounted on the connecting block, a scraper mounted on the spring column, a storage tank mounted on the filter barrel, and a locking component mounted on the filter barrel.

[0008] Furthermore, the filter assembly also includes a drive motor located at the top of the filter barrel, a circular plate at one end of the main shaft, and one end of both the activated carbon filter layer and the filter screen located on the circular plate, with the filter screen located on the outside of the activated carbon filter layer.

[0009] Furthermore, the filter screen is connected to the bottom of the activated carbon filter layer via a connecting ring. Two sets of sliding cylinders are symmetrically arranged at the bottom of the connecting ring, and a groove is provided on the inner side of the filter barrel corresponding to the sliding cylinder. The sliding cylinder and the groove are matched.

[0010] Furthermore, the bottom of the sliding cylinder is equipped with ball bearings.

[0011] Furthermore, the cleaning component also includes a storage groove on the inner side of the connecting block, with multiple sets of spring posts evenly arranged inside the storage groove. One end of each spring post is fixedly connected to the scraper, and one end of the scraper is movably disposed within the storage groove.

[0012] Furthermore, a baffle is provided on the outside of the scraper, and one end of the scraper contacts the filter screen.

[0013] Furthermore, the storage trough is located directly below the scraper and extends through the filter barrel.

[0014] Furthermore, the locking component also includes a fixing plate on the filter barrel corresponding to the storage tank, square blocks on both sides of the fixing plate, threaded rods on the square blocks, and threaded rods connected to the filter barrel.

[0015] Compared with the prior art, the beneficial effects of this utility model include:

[0016] 1. When oil and gas recovery is required, the oil and gas enter the filter barrel from the oil tank through the air inlet pipe. In order to make the activated carbon filter layer adsorb oil and gas more evenly, the operator starts the drive motor, which drives the activated carbon filter layer and filter screen to rotate through the main shaft. This allows the activated carbon filter layer to adsorb oil and gas evenly. Before the activated carbon filter layer adsorbs oil and gas, the filter screen can filter impurities in the oil and gas, which can greatly extend the service life of the activated carbon filter layer.

[0017] 2. To prevent impurities adhering to the filter screen from affecting the absorption of oil and gas by the activated carbon filter layer, the spring force of the spring column ensures that the scraper and the filter screen remain in contact at all times. This allows the scraper to remove impurities from the filter screen as the activated carbon filter layer rotates, thus greatly increasing the service life of the activated carbon filter layer. The baffle is designed to block the scraped impurities, allowing them to slide smoothly into the storage tank for centralized processing by the staff. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] like Figure 1 - Figure 8 As shown, this utility model provides a three-stage oil and gas recovery device for an oil depot, including: a housing 1, a condenser 2 mounted on the housing 1, a filter barrel 3 mounted on the condenser 2, a heater 4 mounted on the filter barrel 3, a liquid storage tank 5 mounted on the condenser 2, and an air inlet pipe 7 mounted on the filter barrel 3; it also includes: a filter assembly mounted on the filter barrel 3, the filter assembly including a drive motor 6 mounted on the filter barrel 3, a main shaft 20 mounted at the output end of the drive motor 6, an activated carbon filter layer 9 mounted on the main shaft 20, and a filter screen 8 mounted on the activated carbon filter layer 9; a cleaning assembly mounted on the filter barrel 3, the cleaning assembly including a connecting block 15 mounted on the filter barrel 3, a spring column 23 mounted on the connecting block 15, a scraper 12 mounted on the spring column 23, a storage tank 14 mounted on the filter barrel 3, and a locking component mounted on the filter barrel 3.

[0030] In the above scheme:

[0031] 1. By starting the drive motor 6, the activated carbon filter layer 9 and the filter screen 8 can be rotated, so that the activated carbon filter layer 9 can absorb oil and gas evenly, making the activated carbon filter layer 9 more effective.

[0032] 2. By setting up the filter screen 8, impurities in the oil and gas can be filtered out, thereby preventing impurities from adhering to the surface of the activated carbon filter layer 9, which can greatly extend the service life of the activated carbon filter layer 9.

[0033] 3. The spring force of the spring column 23 allows the scraper 12 to remain in close contact with the outer side of the filter screen 8. As the filter screen 8 rotates, the scraper 12 can scrape off the impurities filtered out by the filter screen 8, thus facilitating the adsorption of oil and gas by the activated carbon filter layer 9.

[0034] In this embodiment, the filter assembly also includes a drive motor 6 disposed on the top of the filter barrel 3, a circular plate 24 disposed at one end of the main shaft 20, one end of the activated carbon filter layer 9 and the filter screen 8 disposed on the circular plate 24, and the filter screen 8 disposed on the outside of the activated carbon filter layer 9.

[0035] In the above scheme, the activated carbon filter layer 9 can absorb the oil and gas, so that the heater 4 will generate high temperature to desorb the filtered oil and gas.

[0036] In this embodiment, the bottom of the filter screen 8 and the activated carbon filter layer 9 are connected by a connecting ring 10. Two sets of sliding cylinders 18 are symmetrically arranged at the bottom of the connecting ring 10. A groove 11 is provided on the inner side of the filter barrel 3 corresponding to the sliding cylinders 18, and the sliding cylinders 18 and the grooves 11 are matched.

[0037] In the above scheme, the rotation of the activated carbon filter layer 9 can be restricted by the cooperation of the sliding cylinder 18 and the groove 11, thereby preventing the activated carbon filter layer 9 from shaking.

[0038] In this embodiment, a ball bearing 19 is provided at the bottom of the sliding cylinder 18.

[0039] In the above scheme: during the rotation of the activated carbon filter layer 9, the ball bearings 19 can improve the flexibility of the rotation of the activated carbon filter layer 9.

[0040] In this embodiment, the cleaning component also includes a storage groove 22 provided inside the connecting block 15. Multiple sets of spring posts 23 are evenly arranged inside the storage groove 22. One end of the spring post 23 is fixedly connected to the scraper 12, and one end of the scraper 12 is movably disposed in the storage groove 22.

[0041] In the above scheme, the elastic force of the spring column 23 can drive the scraper 12 to maintain contact with the outside of the filter screen 8.

[0042] In this embodiment, a baffle 13 is provided on the outer side of the scraper 12, and one end of the scraper 12 is in contact with the filter screen 8.

[0043] In the above scheme, the baffle 13 can block the impurities scraped off by the scraper 12, so that the impurities can fall into the storage tank 14.

[0044] In this embodiment, the storage tank 14 is located directly below the scraper 12, and the storage tank 14 penetrates the filter barrel 3.

[0045] In the above scheme, the storage tank 14 can be set up to collect impurities in a centralized manner so that staff can process them centrally.

[0046] In this embodiment, the locking component also includes a fixing plate 17 on the filter barrel 3 corresponding to the storage tank 14, square blocks 21 on both sides of the fixing plate 17, and threaded rods 16 on the square blocks 21, which are threadedly connected to the filter barrel 3.

[0047] In the above scheme: the setting of the fixing plate 17 can facilitate the sealing of the storage tank 14, thereby preventing oil and gas leakage, and the setting of the threaded rod 16 can firmly lock the fixing plate 17.

[0048] In this embodiment, when it is necessary to recover oil and gas from the oil depot, the oil and gas enter the filter tank 3 through the air inlet pipe 7. The oil and gas first pass through the filter screen 8 before entering the activated carbon filter layer 9. The operator starts the drive motor 6, which, through the rotation of the main shaft 20, drives the activated carbon filter layer 9 and the filter screen 8 to rotate. This allows the activated carbon filter layer 9 to evenly absorb the oil and gas, maximizing its absorption capacity. While the activated carbon filter layer 9 rotates, two sets of sliding cylinders 18 slide within the groove 11, restricting its rotation and ensuring it remains in motion. The filter screen 8 is designed to be made of a relatively hard material. In addition to filtering oil and gas, it also supports the activated carbon filter layer 9 so that the activated carbon filter layer 9 can remain stable during rotation. After the impurities in the oil and gas are filtered down by the filter screen 8, they will adhere to the outside of the filter screen 8. Through the elasticity of the spring column 23, the scraper 12 can be driven to keep in close contact with the filter screen 8, so that the scraper 12 can continuously scrape the outside of the filter screen 8. The scraped impurities can fall down along the baffle 13, so that the impurities can fall into the storage tank 14. When a lot of impurities are collected in the storage tank 14, the operator can remove the fixing plate 17 by turning the two sets of threaded rods 16, so that the operator can easily remove the impurities from the storage tank 14.
