Description

Technical Field

[0001] The utility model relates to the technical field of oil and gas recovery, in particular to an oil and gas recovery device. Background Art

[0002] During the production, storage, transportation, sales or use of light oil products such as gasoline, some of the oil and gas will evaporate and directly escape into the atmosphere due to the influence of temperature, air pressure, changes in the volume of the vapor and liquid phase in the oil storage tank and other factors, causing oil and gas loss, which will not only cause environmental pollution but also bring economic losses. In the existing oil and gas recovery process, the activated carbon adsorption method is often more common, but the surface area of ​​the activated carbon layer is flat, the adsorption efficiency is low, and thus the recovery efficiency is low. For this reason, we propose an oil and gas recovery device. Utility Model Content

[0020] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.

[0021] See also Figure 1-3 , the utility model provides a technical solution.

[0022] An oil and gas recovery device comprises a base 1; the base 1 is used to support the entire device, and the base 1 is provided with an oil and gas adsorption structure, an activated carbon desorption structure and an oil and gas recovery structure;

[0023] The oil and gas adsorption structure includes: an adsorption tower 2, an air inlet connector 3, an activated carbon adsorption layer 4 and an exhaust pipe 5;

[0024] The adsorption tower 2 is installed on the base 1 , the air inlet joint 3 is installed on the top of the adsorption tower 2 , the exhaust pipe 5 is installed at the bottom of the adsorption tower 2 , and the activated carbon adsorption layer 4 is installed inside the adsorption tower 2 .

[0025] It should be noted that when the oil and gas adsorption begins, the air containing oil and gas is passed into the adsorption tower 2 from the air inlet connector 3, and then the activated carbon adsorption layer 4 adsorbs the oil and gas in the air, and then the clean air flows out from the exhaust pipe 5, thereby completing the oil and gas adsorption process.

[0026] The activated carbon desorption structure comprises: an air pipe valve 6 and a suction and pressure pump 7;

[0027] The air pipe valve 6 is installed on the exhaust pipe 5 , and the suction and pressure pump 7 is installed on the top of the adsorption tower 2 .

[0028] It should be noted that during the adsorption process, oil and gas are adsorbed on the surface of the activated carbon. Once the activated carbon approaches its designed adsorption limit, the carbon bed must be regenerated to continue to function as an adsorbent. The oil and gas recovery system regenerates the carbon by exposing it to a high vacuum (negative pressure). The high vacuum can generate enough desorption energy to destroy the molecular-level adhesion between hydrocarbon molecules and activated carbon particles. Once this adhesion is broken, high-concentration oil and gas will be released from the activated carbon particles. During the desorption process, the air pipe valve 6 is closed, the interior of the adsorption tower 2 is airtight, and then the suction pump 7 is started to evacuate the interior of the adsorption tower 2 to desorb the oil and gas from the surface of the activated carbon.

[0029] The oil and gas recovery structure includes: a recovery tower 16, a gas pipeline 8, a pipeline gas valve 9, a vacuum pump 10, a random packing layer 11, an oil inlet joint 12, an oil outlet pipe 13, an oil pump 14 and a collection tank 15;

[0030] The recovery tower 16 is installed on the base 1, the air pipe 8 is connected between the adsorption tower 2 and the bottom of the recovery tower 16, the pipeline air valve 9 is installed between the air pipe 8, the air pump 10 is installed on the air pipe 8, the random packing layer 11 is installed inside the recovery tower 16, the oil inlet joint 12 is opened at the top of the recovery tower 16, the collection tank 15 is installed on the upper side of the base 1, the oil outlet pipe 13 is connected between the recovery tower 16 and the collection tank 15, and the oil pump 14 is installed on the oil outlet pipe 13.

[0031] It should be noted that the desorbed oil and gas are sucked into the recovery tower 16 through the air pipe 8 by the vacuum pump 10, and continuously move upward in the recovery tower 16, passing through the random packing layer 11. At the same time, the oil products are pumped into the recovery tower 16 from the oil inlet joint 12 from the tank storing the oil products in the oil depot and flow to the surface of the random packing layer 11, so that the oil and gas moving upward subsequently come into contact with the liquid oil products on the surface of the random packing layer 11. This contact causes the concentrated oil and gas to continuously dissolve in the liquid oil products, and then the oil pump 14 can be used to pump the oil products into the collection tank 15 through the oil outlet pipe 13 for collection.

[0032] Preferably, further, the random packing layer 11 is composed of a plurality of block-shaped deposits of PVC material, and gaps are provided between each of the deposits.

[0033] It should be noted that the random packing layer 11 can provide a sufficiently large contact surface area for the downwardly flowing oil product and the upwardly moving oil and gas.

[0034] Preferably, further, the collecting tank 15 is provided with an oil outlet tap.

[0035] It should be noted that the oil outlet tap is used to facilitate the discharge of the oil in the collection tank 15.

[0036] Preferably, further, the surface of the activated carbon adsorption layer 4 is configured to be wavy.

[0037] It should be noted that the wavy surface of the activated carbon adsorption layer 4 can increase the surface area of ​​the activated carbon adsorption layer 4, so that the activated carbon adsorption layer 4 can be in more sufficient contact with the oil and gas.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
