Description

Technical Field

[0001] The invention relates to the technical field of oil and gas recovery, and in particular to a combined oil and gas recovery device. Background Art

[0002] Oil and natural gas are two major fossil fuels that are widely used in global energy supply and industrial production. Oil is a liquid hydrocarbon, mainly composed of carbon and hydrogen elements. It is usually located in underground reservoirs and extracted through drilling technology. Natural gas is a gaseous hydrocarbon composed mainly of methane (CH4), usually located near oil or coal mines. Natural gas is usually transported by pipeline, and can also be transported over long distances by liquefied natural gas (LNG).

[0003] During the transportation of gasoline, due to its volatile components, oil and gas will be dispersed due to factors such as temperature and pressure changes. This oil and gas dispersion not only wastes precious energy, but also has a certain impact on the environment and air quality. Therefore, an oil and gas recovery device is needed at this time. The oil and gas recovery device is a device used to recover and control the oil and gas volatilized during the transportation, storage and refueling of petroleum products. However, the existing oil and gas recovery device has a low oil and gas recovery rate and cannot effectively convert and capture all the escaped oil and gas. The suction efficiency is poor and may not be able to quickly and effectively capture the oil and gas. The filter is easily clogged by dust and oil and gas impurities, resulting in a decrease in filtration efficiency, which in turn affects the oil and gas recovery effect. Therefore, the present invention proposes a combined oil and gas recovery device to solve the problems mentioned in the above background technology. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a combined oil and gas recovery device.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: A combined oil and gas recovery device comprises a recovery bin, a container base is arranged below the recovery bin, a frustum is arranged on the upper part of one side of the container base, a stereoscopic tube is connected between the frustum and the bottom of the upper recovery bin, a plurality of air inlets are arranged around the stereoscopic tube, a filter screen is installed on the outer side of the air inlet, a condensation chamber is installed above the recovery bin, a filter cover seat is arranged on the upper side of the recovery bin, an activated carbon filter element corresponding to the upper outlet of the condensation chamber is arranged on the lower side of the filter cover seat, and a handle is fixedly installed on the outer side of the filter cover seat; A refrigeration element is arranged inside the condensing chamber, a guide pipe on one side is connected to the lower part of the condensing chamber, and an air inlet pipe 1 on the other side is connected to one side of the air inlet pipe 1, and an air inlet pipe 2 is connected to the outer end of the air inlet pipe 2.

[0006] Preferably, there is a gap between the three-dimensional tube and the lower frustum, and there is a gap between the edge of the frustum and the container base, and the recovered oil enters the interior of the container base through the gap.

[0007] Preferably, a scraper is provided on the outside of the filter, and the scraper slides up and down on the outside of the air inlet, so that the outside of the filter is cleaned by sliding the scraper.

[0008] Preferably, an induced draft fan is installed between the telescopic hose and the second air inlet pipe, and a wind hood is installed at the outer end of the telescopic hose.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] Reference Figure 1-6 A combined oil and gas recovery device includes a recovery bin 1, a container base 2 is arranged below the recovery bin 1, a frustum 8 is arranged on the upper part of one side of the container base 2, a stereoscopic tube 9 is connected between the frustum 8 and the bottom of the upper recovery bin 1, a plurality of air inlets 11 are arranged around the stereoscopic tube 9, a filter screen 13 is installed on the outer side of the air inlet 11, a condensation chamber 12 is installed above the recovery bin 1, a filter cover seat 3 is arranged on the upper side of the recovery bin 1, an activated carbon filter element 15 corresponding to the upper outlet of the condensation chamber 12 is arranged on the lower side of the filter cover seat 3, and a handle 4 is fixedly installed on the outer side of the filter cover seat 3. The recovery device can absorb the oil and gas escaped from the surrounding environment through the air inlet 11 The oil and gas enter the bottom of the recovery bin 1 through the filter 13. The filter 13 can isolate most of the external dust. The oil and gas rise and enter the condensation chamber 12. When the temperature of the oil and gas drops to the condensation point of certain components, the gas component will become liquid, thereby realizing the recovery of the oil and gas. At this time, a small amount of low-concentration oil and gas will pass through the activated carbon filter element 15 in the upper filter cover seat 3. The activated carbon has a large specific surface area and can effectively absorb harmful gases in the oil and gas, especially organic volatiles. At the same time, the volatile organic compounds (VOCs) in the oil and gas are adsorbed on the solid surface, so that the filter cover seat 3 can be easily removed for subsequent recovery or treatment. Furthermore, a refrigeration element is arranged inside the condensing chamber 12, a guide pipe 7 on one side and an air inlet pipe 16 on the other side are connected to the lower part of the condensing chamber 12, an air inlet pipe 2 18 is connected to one side of the air inlet pipe 16, an outer end of the air inlet pipe 2 18 is connected to a telescopic hose 5 located outside the recovery bin 1, the interface between the guide pipe 7 and the condensing chamber 12 is located at the lower side of the upper end of the air inlet pipe 16, and the lower end of the guide pipe 7 is connected to the container base 2, an induced draft fan 6 is installed between the telescopic hose 5 and the air inlet pipe 2 18, and a wind hood 10 is installed at the outer end of the telescopic hose 5. In addition to the oil and gas entering through the air inlet 11, the wind hood 10 connected to the telescopic hose 5 can also be placed in the dissipation area, and the oil and gas are absorbed into the recovery bin 1 through the induced draft fan 6. Two different oil and gas inhalation pathways are used to adapt to different oil and gas recovery scenarios. The above-mentioned oil condensed into liquid in the condensing chamber 12 enters the lower container base 2 through the guide pipe 7; Furthermore, the upper end of the air inlet pipe 16 is higher than the bottom side of the condensing chamber 12, and the upper side of the air inlet pipe 16 is rotatably connected to the left and right sides with a one-way valve plate 17, and a torsion spring is provided at the transition of the one-way valve plate 17. The oil and gas entering the recovery bin 1 from the air inlet 11 or the wind cover 10 enter the condensing chamber 12 through the air inlet pipe 16. Due to the height of the upper end of the air inlet pipe 16 and the setting of the one-way valve plate 17, the condensing oil is prevented from returning. Furthermore, the upper side of the cone 8 is rotatably connected to a rotating shaft 23 located inside the recovery bin 1, and an induced draft fan 20 is fixedly installed on the upper end of the rotating shaft 23. A plurality of fan plates 19 are arranged on the upper side of the induced draft fan 20, and the plurality of fan plates 19 are rotatably connected to the recovery bin 1. The lower side of the cone 8 is provided with a motor 25 installed in the container base 2, and the output shaft of the motor 25 is fixedly connected to the upper rotating shaft 23. The fan plates 19 are arranged obliquely, and a plurality of capture holes 24 are evenly arranged on the surface of the fan plates 19, and the plurality of capture holes 24 are arranged in a linear array. The motor 25 inside the container base 2 is started, and the output shaft of the motor 25 drives the upper rotating shaft 23 to rotate, and the rotating shaft 2 3 drives the upper induced draft fan 20 to work, causing negative pressure inside the recovery bin 1, so that the external oil and gas enter the recovery bin 1 through the air inlet 11, and the airflow passing through the fan plate 19 drives the fan plate 19 to rotate. The rotating fan plate 19 can capture the passing liquid oil droplets through the capture holes 24 opened inside it, so that the oil accumulates on the fan plate 19. Since the fan plate 19 is inclined, the oil will fall naturally, and then fall to the surface of the lower frustum 8 through the three-dimensional tube 9. There is a gap between the three-dimensional tube 9 and the lower frustum 8, and there is a gap between the edge of the frustum 8 and the container base 2. The recovered oil enters the container base 2 through the gap; Furthermore, a plurality of scrapers 21 corresponding to the air inlet 11 are arranged inside the recycling bin 1, and the scrapers 21 are rotatably connected to the recycling bin 1. A scraper 14 is arranged outside the filter 13, and the scraper 14 slides up and down outside the air inlet 11. The outside of the filter 13 is cleaned by sliding the scraper 14 to ensure the long-lasting high-quality passing efficiency and dust filtering effect of the external filter 13. A rotating wheel 26 is fixed at the connection of the scraper 21, and a cam 22 corresponding to the rotating wheel 26 is fixed on the peripheral side of the rotating shaft 23. The edges of the plurality of rotating wheels 26 are all provided with corresponding cams 2 2, the oil gas passes through the filter screen 13, and part of the oil is contaminated and adsorbed on the inner side of the filter screen 13. When the above-mentioned rotating shaft 23 rotates, the rotating shaft 23 guides the scraper 21 connected to the rotating wheel 26 to swing up and down through the peripheral cam 22 and the corresponding rotating wheel 26. The rotating wheel 26 is sleeved on the outer side of the cam 22 through the gap. When the cam 22 continues to rotate, the scraper 21 is guided to swing up and down repeatedly, thereby cleaning the inner side of the filter screen 13, and scraping off the oil accumulated on the inner side of the filter screen 13, and entering the container base 2 below through the three-dimensional tube 9.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
