[0041] In the embodiment of the present application, the first adsorption drying tank 301 and the second adsorption drying tank 311 of the adsorption drying unit 300 work alternately (the adsorption regeneration cycle is set to 20 minutes: adjustable). When the first adsorption drying tank 301 is performing adsorption drying, the second adsorption drying tank 311 is in a depressurization regeneration state, and vice versa. The first adsorption drying tank 30 and the second adsorption drying tank 311 are filled with high-efficiency adsorption materials, a lower layer of aluminum oxide and an upper layer of molecular sieves (the volume ratio is 5:1, which can be adjusted as needed), and moisture is adsorbed to obtain dry compressed air.

This application uses high-quality switching valves through the setting of system structure, and realizes automatic operation through the control system without manual intervention, thereby improving work efficiency and safety.

[0045] In the present application, the first air intake electric valve 302 and the second air intake electric valve 312 control the entry of compressed air; the first air outlet one-way valve 303 and the second air outlet one-way valve 313 ensure the one-way flow of dry air; the first pressure relief electric valve 304 and the second pressure relief electric valve 314 are used to introduce pressure relief gas during the regeneration stage; the first muffler 305 and the second muffler 315 are used to reduce system noise; the first safety valve 306 and the second safety valve 316 are used to automatically release pressure when the system is over-pressured, thereby ensuring the safety of the adsorption drying system.

[0046] In some embodiments, a connecting pipeline is provided on the top of the first adsorption drying tank 301 and the second adsorption drying tank 311 of the present application, and a system electric valve 310 is provided on the connecting pipeline. The first adsorption drying tank 301 and the second adsorption drying tank 311 share the system electric valve 310. The system electric valve 310 is in a normally open adjustable mode and can flow in both directions, and is used to automatically adjust and switch the analytical regeneration gas volume of the two drying tanks (the regeneration gas consumption is ≤10% of the adsorption gas volume).

[0047] In some embodiments, the outlets of the first gas outlet check valve 303 and the second gas outlet check valve 313 are combined into a compressed air outlet pipeline, and a primary filter 320 and a secondary filter 330 are arranged on the compressed air outlet pipeline. In some specific embodiments, the primary filter 320 uses a C-class filter element to remove impurities ≥1 μm in the gas (mainly fine particles generated by adsorbent analysis and regeneration); the secondary filter 330 uses an A-class filter element to remove impurities ≥0.01 μm in the gas (mainly fine dust generated by adsorbent analysis and regeneration).

[0048] The first adsorption drying tank 301 of the present application performs adsorption drying while the second adsorption drying tank 311 performs analysis and regeneration mode: compressed air enters the first adsorption drying tank 301 from the first air inlet electric valve 302, and most of the compressed air after adsorption is discharged from the first air outlet one-way valve 303, and then discharged through the primary filter 320 and the secondary filter 330 in sequence; at the same time, a small part of the compressed air after adsorption from the first adsorption drying tank 301 is discharged from the two-way system electric valve 310 into the second adsorption drying tank 311 for pressure relief and analysis, and the compressed air after analysis and regeneration is emptied through the second pressure relief electric valve 314 and the second muffler 315 in sequence; when the adsorption of the adsorption drying tank A301 reaches one adsorption cycle , the adsorption drying unit 300 switches to the second adsorption drying tank 311 for adsorption drying while the first adsorption drying tank 301 performs analysis and regeneration mode: compressed air enters the second adsorption drying tank 311 from the second air inlet electric valve 312, and most of the compressed air after adsorption is discharged from the second air outlet one-way valve 313, and then is discharged through the primary filter 320 and the secondary filter 330 in sequence; at the same time, a small part of the compressed air after adsorption from the second adsorption drying tank 311 is discharged from the two-way system electric valve 310 into the first adsorption drying tank 301 for pressure relief and analysis, and the compressed air after analysis and regeneration is emptied through the first pressure relief electric valve 304 and the first muffler 305 in sequence; and the operation is repeated in this alternating cycle.

[0049] The adsorption drying unit 300 of the present application is energy-saving without heat regeneration.

There is no need to consume heat source energy or vacuum desorption energy, and the system has a significant energy-saving effect.

[0050] Working method: After the air is compressed by the air compression unit 100 and the pressure stabilizing and dehydrating unit 200, the air is decompressed to the required pressure range and enters the adsorption drying unit 300. The first air inlet electric valve 302 is opened, and the first pressure relief electric valve 304 is closed. The gas enters the first adsorption drying tank 301 from the bottom of the first adsorption drying tank 301 for adsorption drying. After the gas is adsorbed and dried from bottom to top in the first adsorption drying tank 301, it is discharged from the top of the first adsorption drying tank 301 through the first air outlet check valve 303, and then filtered through the primary filter 320 and the secondary filter 330. The filtered dry and clean compressed air is transported to the designated oil and gas recovery device system.

[0051] While the first adsorption drying tank 301 is adsorbing moisture, the second adsorption drying tank 311 is in the analysis regeneration mode.

[0052] The analysis mode is: close the first air intake electric valve 302, open the first pressure relief electric valve 304, and the part of the compressed gas after the moisture adsorbed by the first adsorption drying tank 301 enters the second adsorption drying tank 311 through the system electric valve 310 to remove the adsorbed moisture by pressure relief desorption and adsorption waste heat heating, and the gas after analysis and regeneration is discharged through the second pressure relief electric valve 314 and the second muffler 315 in turn.

[0053] Similarly, when the compressed air is filtered, pressure-stabilized, dehydrated, and decompressed to the required pressure range, it enters the adsorption drying unit 300, the second air inlet electric valve 312 is opened, and the second pressure relief electric valve 314 is closed, and the gas enters the second adsorption drying tank 311 from the bottom of the second adsorption drying tank 311 for adsorption drying. The gas is adsorbed and dried from bottom to top in the second adsorption drying tank 311, and then discharged from the top of the second adsorption drying tank 311 through the second air outlet check valve 313, and then filtered by the primary filter 320 and the secondary filter 330. The filtered, dry and clean compressed air The air is transported to the designated oil and gas recovery device system; while the second adsorption drying tank 311 is adsorbing moisture, the first adsorption drying tank 301 is in the analysis and regeneration mode, the second air intake electric valve 312 is closed, and the second pressure relief electric valve 314 is opened. The part of the compressed gas after the moisture adsorption by the second adsorption drying tank 311 enters the first adsorption drying tank 301 through the system electric valve 310 to remove the adsorbed moisture by pressure relief desorption and adsorption waste heat heating. The gas after analysis and regeneration is discharged through the first pressure relief electric valve 304 and the first muffler 305 in sequence.

[0054] It can be seen from the structure of the present application that the air supply system for oil and gas recovery of the present application can achieve efficient drying of compressed air. The present application adopts a three-stage filter and adopts a high-efficiency, renewable adsorption material, which can quickly and effectively remove impurities and moisture in the compressed air and improve the dryness of the gas. The adsorption drying unit adopts double tanks to work alternately, which improves the drying efficiency and reduces energy consumption. The air supply system of the present application ensures the safety and reliability of the system by setting a three-stage safety valve and a three-stage automatic drainer. The setting of the muffler effectively reduces the system noise and improves the working environment.

[0055] The air source supply system for oil and gas recovery in the present application has a wide range of applications and can be applied to various types of air compressors, and can meet the needs of operating oil and gas recovery devices in specific occasions such as oil depots and docks where there is no instrument air and nitrogen source.
