Description

Technical Field

[0001] The present application relates to the field of oil and gas recovery and processing, and in particular to an oil and gas recovery testing device. Background Art

[0002] At present, the main purpose of oil and gas recovery is to reduce the oil and gas content in the air and to ensure the safety around gas stations to a certain extent. During the oil and gas recovery process, the concentration of oil and gas in the air is detected. When the oil and gas concentration is high, necessary measures are taken to ensure the safety around gas stations.

[0003] In the process of recovering oil and gas in the existing technology, the external air is often directly sucked into a condenser, and then the change in the weight of the condenser is used to measure the content of the oil and gas liquefied into liquid, and then the accurate oil and gas concentration is inferred.

[0004] However, the inventor believes that the above technical solution has the following disadvantages: The outside air will contain moisture and dust impurities. The liquefied part of the air contains not only oil and gas but also moisture, which will lead to inaccurate measurement results. If it is filtered through a filter, after a period of use, the filter will adhere to too much dust, and the replacement process is cumbersome, making it difficult to stably and continuously handle the moisture and impurities in the outside air while ensuring oil and gas recovery. Summary of the invention

[0005] In order to improve the problem of difficulty in stably and continuously processing moisture and impurities in the external air while ensuring oil and gas recovery, the present application provides an oil and gas recovery testing device.

[0006] The oil and gas recovery test device provided in this application adopts the following technical solution: A oil and gas recovery test device comprises: a condenser for receiving oil and gas and condensing the oil and gas into a liquid state in the condenser; a conveying member for constructing a first conveying cavity and a second conveying cavity for conveying oil and gas into the condenser; a filter member for forming a filter area for filtering out water vapor and impurities in the first conveying cavity and the second cavity; a driving member for allowing external air to be added to the condenser along the first conveying cavity and / or the second conveying cavity; wherein, when the external air is added to the condenser along the first conveying cavity, the external air is added to the condenser, and part of the external air is discharged along the second conveying cavity; when the external air is added to the condenser along the second conveying cavity, the external air is added to the condenser, and part of the external air is discharged along the first conveying cavity; and the first conveying cavity and the second conveying cavity are both provided with an oil and gas concentration detector.

[0007] By adopting the above technical solution, the first delivery cavity and the second delivery cavity are used to add the external air containing oil and gas into the condensation tank to realize the collection of oil and gas. The filter element is used to filter out water vapor and impurities, so that the external air entering the condensation tank contains only normal gas and oil and gas, and the oil and gas will be liquefied into liquid after condensation, thereby realizing the collection of oil and gas. In addition, when the external air is added to the condensation tank along the first delivery cavity, the external air is added to the condensation tank, and part of the external air is discharged along the second delivery cavity; when the external air is added to the condensation tank along the second delivery cavity, the external air is added to the condensation tank, and part of the external air is discharged along the first delivery cavity, so that the filter element of the first delivery cavity or the second delivery cavity can be back-blown and cleaned while detecting the oil and gas in the air.

[0008] Optionally, the direction in which external air enters the first delivery cavity is parallel to the ground; the direction in which external air enters the second delivery cavity is perpendicular to the ground and vertically upward.

[0009] By adopting the above technical solution, when collecting oil and gas, the oil and gas concentration of the external air at different positions can be detected by using the collection direction of the first delivery cavity parallel to the ground and the delivery direction of the second delivery cavity perpendicular to the ground. The first delivery cavity mainly collects and tests the oil and gas in the air above the ground, mainly at the height of the human body, while the second delivery cavity mainly collects and tests the oil and gas in the air close to the ground, so that there are at least two groups of ways to measure the oil and gas concentration, and the oil and gas concentration at different positions is tested. This can prevent the dangerous situation of open flames at the height of a normal person and the dangerous situation of open flames close to the ground.

[0010] Optionally, the conveying member is also used to form a total connecting cavity; the total connecting cavity is used to connect the first connecting cavity and the second connecting cavity with the condensation tank; a condensation component is arranged in the condensation tank; the condensation component is used to form a condensation area in the condensation tank; the total connecting cavity is connected with the condensation area; a receiving area is also formed in the condensation tank, which is located below the condensation area and is used to receive liquid oil and gas.

[0011] Optionally, the condensation assembly includes: a sealing plate, a total condenser and a plurality of sub-condensers; the plurality of sub-condensers are arranged in a circular array; the total condenser is connected to the plurality of sub-condensers; the total condenser is located in the middle of the plurality of sub-condensers; two sealing plates are provided, respectively located at the upper and lower parts of the sub-condensers; the sealing plate and the sub-condensers form the condensation area; a gap connected to the receiving area is formed between the plurality of sub-condensers.

[0012] By adopting the above technical solution, after adding the air containing oil and gas into the cooling area, the air containing oil and gas will gather between the multiple sub-condensing tubes, and then be discharged outward through the gaps between the multiple sub-condensing tubes. Since the air will be liquefied after entering between the multiple sub-condensing tubes, the liquefied oil and gas will fall directly, and when there is a lot of oil and gas, some of the oil and gas will not be liquefied, and then as the air is discharged outward from the gaps between the multiple sub-condensing tubes, the oil and gas in the air will contact the tube wall of the condensing tube, and the tube wall temperature of the condensing tube is lower, which can make the oil and gas be liquefied, thereby improving the effect of completely liquefying the oil and gas, thereby greatly improving the efficiency of oil and gas recovery.

[0013] Optionally, the main condenser is connected to the multiple branch condensers through a branch head; the main condenser is connected to the branch head through a rotating connector so that the branch head and the multiple branch condensers can rotate relative to the main condenser; a rotating power part is provided at the branch head, and the rotating power part is used to drive the branch head to rotate so that the multiple branch condensers rotate in the condensation tank.

[0014] By adopting the above-mentioned technical scheme, as the oil and gas pass through the gaps between the multiple sub-condensers, they will condense and adhere to the sub-condensers. Then, as the amount of liquid oil and gas adhering to the sub-condensers gradually increases, an oil film will be formed on the outer wall of the sub-condensers, which will prevent the air from directly contacting the sub-condensers. The temperature difference between the air and the oil film is smaller than the temperature difference between the air and the outer wall of the sub-condensers, which will cause the condensation effect of the oil and gas to deteriorate. Then, by adopting a rotating power part to drive the multiple sub-condensers to rotate, the liquid oil and gas adhering to the sub-condensers can be thrown out by inertia, thereby keeping the oil and gas in direct contact with the outer wall of the sub-condensers at all times.

[0015] Optionally, a guide member is arranged in the condensation area, and the guide member is arranged below the baffle located at the upper part of the sub-condensing tube; the guide member forms a guide chamber connected to the inner wall surface of the condensation tank; the guide member also forms a plurality of air outlet cavities connected to the guide chamber and air outlets connected to the air outlet cavities; the air outlet is located in the condensation area; the main connecting cavity is connected to the guide chamber.

[0016] Optionally, one end of the total condenser extends into the lower part of the condensation tank, and the other end of the total condenser extends into the upper part of the condensation tank; wherein, the end of the total condenser extending into the lower part of the condensation tank is the inlet end; and the end of the total condenser extending into the upper part of the condensation tank is the outlet end, so that the condensate flows unidirectionally in the cooling area.

[0017] By adopting the above technical solution, since the coolant in the sub-condensing tube flows in one direction, the coolant in the sub-condensing tube can be discharged in time and the temperature of the sub-condensing tube can be better guaranteed, so that the low temperature of the condensation area can be better guaranteed to improve the effect of oil and gas condensation. However, this will also cause the total condensing tube and the sub-condensing tube to penetrate the condensing tank. When the sub-condensing tube rotates, it is difficult to realize that the total conveying cavity adds air to the condensation area. Therefore, by using the setting of the guide member, the guide member can be rotated with the sub-condensing tube, and the guide member is partially located between the multiple sub-condensing tubes, so that the air can be directly added to the condensation area between the multiple sub-condensing tubes. Thereby, the air is first added between the multiple sub-condensing tubes, and the air is diffused from the area between the multiple sub-condensing tubes to the area outside the multiple sub-condensing tubes. The area between the multiple sub-condensing tubes has a small space and a low temperature, which is convenient for condensing the oil and gas in the air. The purpose of air diffusion outward is mainly to allow the air to contact the sub-condensing tube and further condense the oil and gas in the air. The air is added to the condensation area through the guide member, which realizes that the air enters the condensation area and does not affect the rotation of the sub-condensing tube. The main purpose of rotating multiple sub-condensers is to make the sub-condensers act as turbofans. The sub-condensers can make the air flow in one direction, even if the air diffuses from between the multiple sub-condensers to outside the multiple sub-condensers, to avoid disordered air flow caused by poor air fluidity in the condensers, that is, to avoid the reciprocating air passing through the gaps between the multiple sub-condensers, which causes the cold capacity of the sub-condenser part to condense the air without air, thereby reducing the probability of doing useless work.

[0018] Optionally, the total condenser is bent to form multiple rows below the condensation tank; a heat sink and a heat sink fan are provided at the total condenser; the heat sink fan cools the coolant in the condenser through the heat sink; and the airflow output outward by the heat sink fan intersects with the cooling tank.

[0019] Optionally, a protective cover is provided on the outside of the cooling fan and the cooling plate; a through opening is formed on the protective cover so that the airflow formed by the cooling fan can intersect with the cooling tank after passing through the through opening; a baffle is provided at the through opening, and the baffle is used to prevent liquid from falling onto the cooling fan through the through opening and to allow the airflow formed by the cooling fan to be output outward; the second conveying cavity is connected to the protective cover.

[0020] By adopting the above technical solution, it is mainly realized that the air is blown upward from the opening, and then the wind will blow on the condenser. Since there are sub-condensers and the main condenser on the condenser, the temperature of the outer wall of the condenser is relatively low. After the external air contacts the condenser, the moisture and oil gas in the air will be cooled and liquefied, so that a layer of liquid will adhere to the outer wall of the condenser. Blowing air upward through the opening can promote the flow of gas around the condenser, especially making the liquid at the bottom of the condenser easier to be blown down and then fall on the baffle, which will block the liquid and prevent the liquid from flowing into the cooling fan.

[0021] Optionally, the filter element forms a first filter area and a second filter area, wherein the first filter area is arranged at the first conveying cavity; the second filter area is formed outside the protective cover; the second filter area and the protective cover form an installation area, and the heat sink and the heat dissipation fan are both arranged in the installation area.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: 1. Part of the external air is transported to the condensation tank through the first delivery cavity for condensation, and part of the external air is discharged from the second delivery cavity to the outside, so as to backwash and clean the filter element, realize stable and continuous treatment of moisture and impurities in the external air while ensuring the recovery of oil and gas; 2. The oil and gas in the external air are condensed by forming a condensation area through multiple sub-condensation tanks and directly adding external air into the condensation area, and then the gaps between the multiple condensation tanks are used to discharge the external air and further condense the oil and gas in the external air, thereby increasing the degree of condensation treatment of the oil and gas in the external air; 3. The guide piece is used to directly add external air into the condensation area during the rotation of multiple sub-condensation tanks, and the rotation of multiple sub-condensation tanks is used to get rid of the oil adhering to the sub-condensation tubes, so as to better ensure the low temperature state of the sub-condensation tubes.

[0025] The following is combined with Figure 1-16 This application is described in further detail.

[0026] The embodiment of the present application discloses an oil and gas recovery testing device.

[0027] An oil and gas recovery test device comprises: a mobile body 1, a condensation tank 2, a conveying component 3, a filtering component and a driving component 5.

[0028] The condenser 2 is used to receive oil and gas and condense the oil and gas into a liquid state in the condenser 2. The condenser 2 is a tank body with a spherical bottom. The conveying member 3 is used to construct the first conveying cavity and the second conveying cavity for conveying oil and gas to the condenser 2. The conveying member 3 adopts a tube body in this embodiment, and uses the tube body to convey oil and gas or air containing oil and gas, mainly for conveying air containing oil and gas. The filter element is used to form a filter area in the first conveying cavity and the second conveying cavity to filter out water vapor and impurities. The filter element is a filter mesh layer and a desiccant layer in this embodiment. The filter mesh layer is used to filter out dust and impurities, and the desiccant layer is to put the desiccant into a bag, and then the bag fills part of the first conveying cavity or part of the second conveying cavity. The desiccant layer is mainly used to absorb moisture in the air. So that the air entering the condenser 2 is only oil and gas. The driving member 5 is used to allow external air to be added to the condensation tank 2 along the first delivery cavity and / or the second delivery cavity. The driving member 5 is a pump body. External air can enter the condensation tank 2 from the first delivery cavity alone, or be added to the condensation tank 2 from the second delivery cavity alone, or can be added to the condensation tank 2 from the first delivery cavity and the second delivery cavity at the same time. Among them, the condensation tank 2, the delivery member 3, the filter and the driving member 5 are all installed on the mobile vehicle body 1, so that the oil and gas recovery detection is easy to move and more convenient to use.

[0029] The first delivery cavity and the second delivery cavity are used to add the external air containing oil and gas into the condensation tank 2 to collect the oil and gas. The filter is used to filter out water vapor and impurities, so that the external air entering the condensation tank 2 contains only normal gas and oil and gas, and the oil and gas will be liquefied into liquid after condensation, thereby collecting the oil and gas.

[0030] In this embodiment, the first delivery cavity and the second delivery cavity are connected, and the connection between the two is controlled by setting a control valve. When the external air is added to the condensation tank 2 along the first delivery cavity, the external air is added to the condensation tank 2, and part of the external air is discharged along the second delivery cavity. When the external air is added to the condensation tank 2 along the second delivery cavity, the external air is added to the condensation tank 2, and part of the external air is discharged along the first delivery cavity. When the external air is added to the condensation tank 2 along the first delivery cavity, the external air is added to the condensation tank 2, and part of the external air is discharged along the second delivery cavity; when the external air is added to the condensation tank 2 along the second delivery cavity, the external air is added to the condensation tank 2, and part of the external air is discharged along the first delivery cavity, so that the filter element of the first delivery cavity or the second delivery cavity can be back-blown and cleaned while the oil and gas in the air are detected.

[0031] The first delivery cavity and the second delivery cavity are both provided with an oil and gas concentration detector, which can directly and quickly detect the oil and gas concentration in the air, thereby better controlling the oil and gas concentration to ensure safety.

[0032] Specifically, the direction in which the external air enters the first delivery cavity is parallel to the ground, and the direction in which the external air enters the second delivery cavity is perpendicular to the ground and vertically upward, so that the oil and gas concentration of the external air at different positions can be detected.

[0033] More specifically, the conveying member 3 is also used to form a main connecting cavity. The main connecting cavity is composed of a tube body, and the main connecting cavity is connected to the first conveying cavity and the second conveying cavity through a three-way joint. The main connecting cavity is used to connect the first connecting cavity and the second connecting cavity with the condensation tank 2. A condensation component 6 is arranged in the condensation tank 2. The condensation component 6 is used to form a condensation area 632 in the condensation tank 2; the main connecting cavity is connected to the condensation area 632, and a receiving area is also formed in the condensation tank 2 below the condensation area 632 for receiving liquid oil and gas. Among them, the condensation component 6 adopts the existing technology, and the condensation component 6 is a component capable of refrigeration. Example 2

[0034] The difference from Example 1 is that: On the basis of Example 1, the condensation assembly 6 includes: a sealing plate 61, a total condenser 62 and a plurality of sub-condensers 63. The plurality of sub-condensers 63 are arranged in a circular array, and the total condenser 62 is connected to the plurality of sub-condensers 63. The total condenser 62 is located in the middle of the plurality of sub-condensers 63. Two sealing plates 61 are provided, which are respectively located at the upper and lower parts of the sub-condensers 63; the sealing plate 61 and the sub-condensers 63 form the condensation area 632. A gap 631 connected to the receiving area is formed between the plurality of sub-condensers 63. Among them, the sub-condenser 63 is connected to the total condenser 62 at one end, and the other end extends away from the total condenser 62 by one end and then extends downward, thereby forming a space. Then the sealing plate 61 and the sub-condenser 63 together form the condensation area 632. The air containing oil and gas is discharged outward through the gaps between the plurality of sub-condensers 63. Then the oil and gas in the air will come into contact with the wall of the condenser tube. The wall temperature of the condenser tube is lower, which can liquefy the oil and gas, thereby improving the effect of completely liquefying the oil and gas, thereby greatly improving the efficiency of oil and gas recovery. Example 3

[0035] The difference from Example 2 is that: The main condenser 62 is connected to the plurality of branch condensers 63 through a branch head. The main condenser 62 is connected to the branch head through a rotating connector, and the rotating connector adopts a rotating joint. So that the branch head and the plurality of branch condensers 63 can rotate relative to the main condenser 62. A rotating power part is provided at the branch head, and the rotating power part is used to drive the branch head to rotate so that the plurality of branch condensers 63 rotate in the condensation tank 2. In this embodiment, the rotating power part adopts a motor and a transmission component, and the motor drives the branch head outside the condensation tank 2 to rotate through the transmission component, thereby realizing the rotation of the plurality of branch condensers 63. Among them, the transmission component adopts gear transmission or belt transmission.

[0036] One end of the total condensation pipe 62 extends into the lower part of the condensation tank 2, and the other end of the total condensation pipe 62 extends into the upper part of the condensation tank 2; wherein, the end of the total condensation pipe 62 extending into the lower part of the condensation tank 2 is the inlet end; the end of the total condensation pipe 62 extending into the upper part of the condensation tank 2 is the outlet end, so that the condensate flows unidirectionally in the cooling area. The unidirectional flow means that the coolant enters from the lower part and is discharged from the upper part, forming a cycle.

[0037] As the oil and gas pass through the gaps between the multiple sub-condensers 63, they will condense and adhere to the sub-condensers 63. Then, as the amount of liquid oil and gas adhering to the sub-condensers 63 gradually increases, an oil film will be formed on the outer wall of the sub-condensers 63, which will prevent the air from directly contacting the sub-condensers 63. The temperature difference between the air and the oil film is smaller than the temperature difference between the air and the outer wall of the sub-condensers 63, which will cause the condensation effect of the oil and gas to deteriorate. Then, by using a rotating power part to drive the multiple sub-condensers 63 to rotate, the liquid oil and gas adhering to the sub-condensers 63 can be thrown out by inertia, thereby keeping the oil and gas in direct contact with the outer wall of the sub-condensers 63 at all times.

[0038] Specifically, a guide member 64 is provided in the condensation area 632, and the guide member 64 is provided below the baffle located at the upper part of the sub-condensation tube 63. The guide member 64 forms a guide chamber 641 connected to the inner wall surface of the condensation tank 2; the guide member 64 also forms a plurality of air outlet channels 642 connected to the guide chamber 641 and air outlets connected to the air outlet channels 642. The air outlets are located in the condensation area 632; the main connection channel is connected to the guide chamber 641. The guide member 64 is a plate body.

[0039] More specifically, the total condenser 62 is bent to form multiple rows below the condensation tank 2; a heat sink 65 and a heat sink fan 66 are provided at the total condenser 62; the heat sink fan 66 cools the coolant in the condenser through the heat sink 65; the airflow output outward by the heat sink fan 66 intersects with the cooling tank.

[0040] Among them, one end of the sub-condenser pipe 63 is connected to the main condenser pipe 62 at the lower part of the cooling tank, and the other end extends away from the main condenser pipe 62 for a distance, then extends upward, and after extending upward for a distance, bends and extends downward, and after repeated bending for many times, a region with an area and volume larger than a single sub-condenser pipe 63 is formed, and finally extends upward to connect with the main condenser pipe 62 at the upper part of the condensation tank 2. Since the number of external sub-condensers 63 on the main condenser pipe 62 is limited, a large-volume condensation area 632 can be formed by repeatedly bending the sub-condensers 63 for many times. Example 4

[0041] The difference from Example 3 is: A protective cover 7 is provided outside the cooling fan 66 and the cooling plate 65. The protective cover 7 is a square shell, and the protective cover 7 completely covers the cooling fan 66 and the cooling plate 65. A through hole 71 is formed on the protective cover 7, and the opening direction of the through hole 71 faces upward, so that the airflow formed by the cooling fan 66 intersects with the cooling tank after passing through the through hole 71. A baffle 8 is provided at the through hole 71, and the baffle 8 is used to prevent liquid from falling onto the cooling fan 66 through the through hole 71 and to allow the airflow formed by the cooling fan 66 to be output outward; the second conveying cavity is connected to the protective cover 7. It mainly realizes blowing air upward from the through hole 71, and then the wind will blow on the condensation tank 2. Since there are branch condensers 63 and main condensers 62 on the condenser tank 2, the temperature of the outer wall of the condenser tank 2 is relatively low. When the external air contacts the condenser tank 2, the moisture and oil gas in the air will be cooled and liquefied, so that a layer of liquid will adhere to the outer wall of the condenser tank 2. By blowing air upward through the through hole 71, the gas flow around the condenser tank 2 can be promoted, especially the liquid at the bottom of the condenser tank 2 can be blown down more easily and then fall onto the baffle 8. The baffle 8 will block the liquid and prevent the liquid from flowing into the cooling fan 66.

[0042] Among them, the specific solution for the blocker 8 is: The blocking member 8 comprises a first plate body 81 and a second plate body 82. There are multiple through openings 71, multiple blocking members 8, and multiple blocking members 8 are respectively located in each through opening 71. The first plate 81 is fixed to one side of the through-port 71, and the second plate 82 is fixed to the other side of the through-port 71. The first plate 81 is located above the second plate 82. The widths of the first plate 81 and the second plate 82 are the same, both greater than half of the width of the through-port 71. The first plate 81 and the second plate 82 are both extended downwardly at an angle. When the liquid adhered to the outer wall of the condensation tank 2 falls to the through-port 71, it will fall on the first plate 81 or the second plate 82, and cannot pass through the first plate 81 and the second plate 82 to enter the cooling fan 66, thereby protecting the cooling fan 66. After the other liquid falls on the first plate 81 or the second plate 82, since the first plate 81 and the second plate 82 extend downward at an angle, the liquid will be transported downward at an angle to the end of the first plate 81 and the second plate 82. In order to better prevent the liquid from overflowing on the first plate 81 and the second plate 82, a V-shaped groove is formed on the first plate 81 and the second plate 82 to accommodate the liquid.

[0043] In order to discharge the liquid in the V-shaped groove outward in time, a guide pipe 83 is respectively arranged at the end of the first plate body 81 and the end of the second plate body 82, and a storage box 84 is arranged on the edge of the protective cover 7. The storage box 84 is connected to the guide pipe 83, so as to collect the liquid falling from the condensation tank 2.

[0044] In other solutions, the outlet pipe 83 is directly connected to the condensation tank 2 and stored through the condensation tank 2 . Example 5

[0045] The difference from Example 4 is that: the filter element forms a first filter area and a second filter area, wherein the first filter area is arranged at the first delivery cavity; the second filter area is formed outside the protective cover 7. The second filter area and the protective cover 7 form an installation area, and the heat sink 65 and the heat dissipation fan 66 are both arranged in the installation area.

[0046] The conveying member 3 includes a first conveying pipe 31, a second conveying pipe 32 and a main conveying pipe 33. The first conveying pipe 31 is used to form a first conveying cavity, the second conveying pipe 32 is used to form a second conveying cavity, and the main conveying pipe 33 is used to form a main connecting cavity. The conveying member 3 also includes an output pipe 4, which is connected to the upper part of the condensing tank 2 and is used to discharge the air without oil and gas after the oil and gas in the air are condensed in the condensing tank 2.

[0047] Specifically, the first delivery pipe 31 is provided with a first drive pump body 34 and a first control valve 35; the second delivery pipe 32 is provided with a second drive pump 36 and a second control valve 37; the output pipe 4 is provided with a third drive pump 38 and a third control valve 39. When external air enters the condensing tank 2 from the first delivery cavity and the second delivery cavity at the same time, the third drive pump 38 is started, and the first drive pump or the second drive pump 36 may be started or not. When external air enters from the first delivery cavity, and part of it enters the condensing tank 2, and part of it is discharged from the second delivery cavity, the first drive pump is started, and the second drive pump 36 and the third drive pump 38 are stopped. In addition, when air enters the condensing tank 2 only from the first delivery cavity or only from the second delivery cavity, it is controlled by the opening and closing states of the first control valve 35, the second control valve 37 and the third control valve 39. Example 6

[0048] The difference from Example 3 is that the rotating power part is composed of a plurality of rotating blades 51. A fixed shaft 52 is set at the connection between the total condensing pipe 62 and the branch condensing pipe 63, and the fixed shaft 52 is located in the condensation area 632. The rotating blades 51 are set on the fixed shaft 52. When the external air enters the condensation area 632, the external air contacts the rotating blades 51, and then the rotating blades 51 are subjected to the driving force of rotation, so that the rotating blades 51 drive the fixed shaft 52 to rotate, and the fixed shaft 52 drives the plurality of branch condensing pipes 63 to rotate, thereby realizing the rotation of the plurality of branch condensing pipes 63. With such a design, the rotary joint and the branch pipe head can be set inside the condensing tank 2, so that the total condensing pipe 62 is fixed relative to the condensing tank 2, which is convenient for sealing the connection between the total condensing pipe 62 and the condensing tank 2, while Example 3 is to set the rotating power part outside the condensing tank 2, so the branch pipe head is connected with the condensing tank 2, and the two can rotate relative to each other, which will increase the difficulty of sealing. Example 7

[0049] The difference from the above embodiment is that: The second delivery pipe 32 is connected to the space inside the protective cover 7. Therefore, when the oil and gas enter through the second delivery pipe 32, the heat dissipation fan 66 can be used to blow upward to dissipate heat and assist the second delivery pipe 32 to intake air.

[0050] The implementation principle of an oil and gas recovery test device in the embodiment of the present application is: The third driving pump 38 is started, and the external air enters the main conveying cavity simultaneously along the first conveying cavity and the second conveying cavity. In this process, the dust impurities and moisture in the external air are filtered out by the filter element, and then the external air is directly entered into the condensation area 632 through the guide element 64. The external air is cooled, which will liquefy the oil and gas in the external air into liquid. The liquid flows downward and contacts the inner wall of the condensation tank 2, thereby collecting the oil and gas. However, in other cases, only part of the oil and gas in the external air is cooled and liquefied, and the other part of the oil and gas flows outward along the gaps between the multiple sub-condensation tubes 63. Since the temperature of the sub-condensation tubes 63 is lower than the condensation area 632 between the multiple sub-condensation tubes 63, this part of the oil and gas will be further liquefied. After liquefaction, the oil and gas will become liquid and some of them will adhere to the sub-condensation tubes 63. By using the setting that the multiple sub-condensation tubes 63 can rotate, the liquid is thrown out under the action of inertia and detaches from the sub-condensation tubes 63 and contacts the inner wall of the condensation tank 2 to achieve collection.

[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
