[0002] With the vigorous promotion of national environmental protection policies, oil and gas recovery devices are widely used in oil depots, gas stations, petrochemicals and other fields. If oil and gas cannot be recovered well, it will pollute the environment while causing oil loss and has great harm. Generally, a condensing oil and gas recovery system is used. It is an energy-saving and environmentally friendly system that has been vigorously promoted in refineries and large oil storage depots in my country in recent years. It condenses the oil and gas generated in the oil inlet and outlet projects through several levels of condensation treatment, condenses and precipitates the oil and water contained in the oil and gas, and then separates the oil and water to completely precipitate the oil, thereby recovering the oil.

[0003] After searching, the patent with announcement number CN203577576U discloses an activated carbon adsorption tank for organic waste gas, and its content records that "it includes an adsorption tank body with a hollow interior, an activated carbon adsorption layer arranged in the adsorption tank body, an air inlet is arranged on the adsorption tank body, and exhaust ports are arranged on the top and bottom of the adsorption tank body. The activated carbon adsorption layer is provided with two layers, and the two activated carbon adsorption layers are arranged up and down. A gas distributor is arranged between the two activated carbon adsorption layers, one of the ports of the gas distributor is connected to the air inlet, and the other port of the gas distributor is tightly connected to the inner wall of the adsorption tank body. A partition plate is arranged between the outer wall of the gas distributor and the inner wall of the adsorption tank body, and the partition plate is arranged horizontally to separate..." From the above, it can be seen that the activated carbon adsorbent in the activated carbon adsorption layer of the patent is not easy to replace, which requires more manpower and economy, and has high cost, and there are certain shortcomings.

[0023] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0024] The following describes some embodiments of the utility model in conjunction with the accompanying drawings to provide an oil and gas recovery device with high-efficiency adsorbent and vacuum desorption.

[0025] Embodiment 1:

[0026] Reference Figure 1-4 , which is the first embodiment of the utility model, provides an oil and gas recovery device with high-efficiency adsorbent and vacuum desorption, including a first adsorption tank 100, a sealing assembly 200, a fastening assembly 300, a supporting assembly 400, a conveying assembly 500 and a second adsorption tank 600.

[0027] Specifically, the first adsorption tank 100 includes a tank body 101, a discharge pipe 105 arranged at the front end of the tank body 101, a sealing plate 106 hinged to the bottom of the discharge pipe 105, and a supporting orifice plate 107 arranged inside the tank body 101. The sealing plate 106 can be rotated to open, and after opening, the adsorbent can be discharged through the discharge pipe 105 for replacement. The rear side of the tank body 101 is provided with an exhaust pipe 102 and a pressure gauge 103. The pressure gauge 103 can detect the pressure in the first adsorption tank 100. When the pressure rises significantly faster, it indicates that the adsorbent is saturated, so that the adsorption tank can be replaced. The exhaust pipe 102 is fixedly connected to the vacuum pump, and the vacuum pump can be used to extract the gas in the first adsorption tank 100 through the exhaust pipe 102, so that the substance adsorbed on the adsorbent falls off and is discharged through the discharge pipe 108.

[0028] Furthermore, a plurality of heating tubes 104 are provided inside the tank body 101, and the plurality of heating tubes 104 can be heated so as to convert the substance adsorbed by the gaseous adsorbent into liquid for recovery. A discharge tube 108 is provided at the bottom of the tank body 101, and the discharge tube 108 can discharge the liquid adsorbent adsorbed substance for recovery.

[0029] Specifically, the sealing assembly 200 is arranged on the top of the first adsorption tank 100. The sealing assembly 200 includes a sealing cover 201 bolted to the top of the tank body 101 and a discharge pipe 202 arranged on the top of the sealing cover 201. The sealing cover 201 can be detached by removable bolts for use, and the discharge pipe 202 can discharge the adsorbed gas.

[0030] Specifically, the fastening assembly 300 includes a long rod 301 arranged outside the discharge pipe 105, a baffle 302 arranged at the front end of the long rod 301, a screw 303 threadedly connected to the baffle 302, and a fastening knob 304 threadedly connected to the baffle 302. The screw 303 can resist the sealing plate 106, and the fastening knob 304 can lock the screw 303 to improve stability. The baffle 302 can block the adsorbent to prevent it from hitting the user, which has high safety.

[0031] Specifically, the support assembly 400 includes a lower support grid 401 placed on the support orifice plate 107, a vertical rod 402 arranged on the top of the lower support grid 401, and an upper support grid 403 interlaced with the vertical rod 402. The upper support grid 403 can be separated from the tank body 101 by moving, and after separation, the lower support grid 401 can be moved upward through the vertical rod 402. After moving to a suitable height, the adsorbent can be thoroughly cleaned so that the adsorbent can be replaced.

[0032] Specifically, the conveying component 500 is arranged on the left side of the first adsorption tank 100. The conveying component 500 includes a conveying pipe 501 arranged on the left side of the first adsorption tank 100, a first valve 502 arranged on the conveying pipe 501, and a second valve 503 arranged on the conveying pipe 501. The first valve 502 can be closed and the second valve 503 can be opened. After the first valve 502 is closed, the first adsorption tank 100 can be vacuum heated for desorption, and after the second valve 503 is opened, adsorption can be performed through the second adsorption tank 600, which greatly improves efficiency.

[0033] Specifically, the second adsorption tank 600 is arranged on the left side of the conveying component 500 . The second adsorption tank 600 has the same structure as the first adsorption tank 100 . Both the second adsorption tank 600 and the first adsorption tank 100 can adsorb, and the coordinated use efficiency is high.

[0034] The working principle and use process of the utility model are as follows: when replacing the adsorbent, the screw 303 of the fastening assembly 300 can be rotated first until the screw 303 is rotated and separated from the sealing plate 106. After separation, the sealing plate 106 is rotated and opened due to the pressure of the adsorbent. After opening, the adsorbent inside the support assembly 400 can be discharged through the discharge pipe 105. During the discharge process, the adsorbent is blocked by the baffle 302 to prevent the adsorbent from hitting the user, which is highly safe. Then, the bolts are removed to separate the sealing cover 201. After separation, the upper support grid 403 is moved to separate from the tank body 101. After separation, the lower support grid 401 is moved upward through the vertical rod 402. After moving to a suitable height, the adsorbent can be thoroughly cleaned, and then the support grid 401 is supported downward after cleaning. Adding adsorbent to the grid 401 saves time and effort, and facilitates the replacement of adsorbent. When in use, the pressure gauge 103 can detect the pressure in the first adsorption tank 100. When the pressure rises significantly faster, it indicates that the adsorbent is saturated, and the first valve 502 can be closed and the second valve 503 can be opened. After the first valve 502 is closed, the first adsorption tank 100 can be vacuum heated and desorbed. During vacuum desorption, a vacuum pump can be used to extract the gas in the first adsorption tank 100 through the exhaust pipe 102, and heated through the heating pipe 104, so that the adsorbed substance on the adsorbent falls off and is discharged through the discharge pipe 108. After the second valve 503 is opened, adsorption can be carried out through the second adsorption tank 600, which greatly improves efficiency.

[0035] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
