Description

Technical Field

[0001] The present application belongs to the technical field of oil and gas recovery, and specifically relates to an energy-saving and environmentally friendly oil and gas recovery and processing device. Background Art

[0002] During energy storage and transportation, the volatilization of oil and gas not only causes a waste of resources, but also causes serious harm to the environment. Oil and gas contain a large amount of volatile organic compounds (VOCs). These substances will undergo photochemical reactions with nitrogen oxides in the air under the action of sunlight to form secondary ozone pollutants, which have a great impact on air quality. At the same time, the volatilization of oil and gas also poses a safety hazard. When the concentration of oil and gas is too high, it is easy to cause explosions and fire accidents when encountering a fire source. The emergence of oil and gas recovery and processing equipment has effectively solved these problems. Oil and gas recovery refers to the collection of volatilized gasoline and gas during the process of loading and unloading gasoline and refueling vehicles. Through one or two methods of absorption, adsorption or condensation, the pollution of oil and gas is reduced, or the oil and gas is converted from gas to liquid and back into gasoline to achieve the purpose of recycling and utilization.

[0003] For example, patent number CN216890803U discloses an energy-saving and environmentally friendly oil and gas recovery and processing device, including an oil storage tank, an oil and gas recovery mechanism provided on one side of the oil storage tank, the oil and gas recovery mechanism including an oil and gas recovery pipe and an oil and gas condensation mechanism, a flange provided on one side of the oil and gas recovery pipe, a solenoid valve provided in the middle of the oil and gas recovery pipe, and a pressure gauge provided on the upper side of the oil and gas recovery pipe. The utility model can lead out volatile gas through the oil and gas lead-out pipe, inject condensed water through the condensed water inlet, and lead out the condensed water through the condensed water outlet after filling the condensate box. The condensate box can cool the oil and gas lead-out pipe, thereby condensing the oil and gas in the oil and gas lead-out pipe, and the condensed gasoline falls back through the oil and gas lead-out pipe, and flows back into the inner side of the oil storage tank through the return oil pipeline. The anti-backflow rack can play an anti-backflow role, so that the gasoline can be recovered through the return oil pipeline.

[0004] During the use of this device, it was discovered that the technology had the following problems: when adding oil to the oil storage tank of this device, air containing moisture would inevitably mix in. This caused the oil vapor volatilized from the oil storage tank after being affected by high temperature to contain not only oil but also water. Therefore, when the device subsequently condensed the volatilized oil vapor, the water vapor mixed in the oil vapor would also be condensed and fall back through the oil and gas outlet pipe. Finally, it would flow back into the oil storage tank through the oil return line. Over time, this would affect the purity of the oil. Therefore, in order to solve this problem, it is necessary to propose an energy-saving and environmentally friendly oil and gas recovery and treatment device. Utility Model Content

This cycle is used to remove the water vapor absorbed by the adsorbent in the adsorption cylinder, thereby restoring the water absorption function of the adsorption cylinder and extending its service life.
