Description

Technical Field

[0001] The utility model relates to the technical field of oil and gas recovery, in particular to a skid-mounted oil and gas recovery adsorption tank. Background Art

[0002] Every year, about 1% of oil and gas is lost due to volatilization. If it is not recycled, the loss will be huge, which will not only cause economic losses, but also pollute the environment and increase safety factors. By implementing the "Oil Field Recovery Project" to establish an oil and gas recovery system, the volatilized oil and gas can be converted into liquid oil products for recycling. This can not only reduce the harm of oil and gas to the human body, but also have better environmental, social and economic benefits.

[0003] The existing treatment method usually adsorbs the oil and gas at room temperature, resulting in a large internal circulation volume of light components, while the adsorption force of light components is weak, it is difficult to obtain a lower concentration of exhaust gas, and it causes the hot spots of the adsorption bed to heat up. The current activated carbon filter element is installed on the activated carbon adsorption box with multiple bolts, so when replacing the activated carbon filter element, tools need to be used to install and remove the bolts one by one, making the operation of replacing the activated carbon filter element more troublesome. Summary of the Invention

[0004] The purpose of the utility model is to provide a skid-mounted oil and gas recovery adsorption tank to solve the above-mentioned defects caused by the prior art.

[0005] A skid-mounted oil and gas recovery adsorption tank comprises an adsorption tank body, a cooling chamber and an adsorption part. A feed pipe is provided at the top of the adsorption tank body, a discharge pipe is provided at the bottom of the adsorption tank body, and a cooling mechanism is provided on one side of the adsorption tank body. The cooling mechanism cools the external air and injects it into the interior of the cooling chamber, thereby accelerating the cooling and adsorption speed of the oil and gas through the cooling chamber. A positioning mechanism is provided inside the adsorption tank body, and the positioning mechanism clamps adsorption parts of different sizes to meet the adsorption of different quantities of oil and gas, while facilitating the disassembly and replacement of the positioning mechanism and the adsorption part.

[0006] Preferably, the cooling mechanism includes an air intake pipe, an air intake box, a fan, a semiconductor refrigeration component and a cooling chamber. The bottom end of the air intake pipe is connected to the top of the air intake box, one side of the air intake box is connected to the fan output end, one side of the adsorption tank is fitted with a semiconductor refrigeration component, the other side of the air intake pipe is connected to the outside of the adsorption tank, and the cooling chamber is distributed in a ring shape inside the adsorption tank.

[0007] Preferably, the adsorption tank is connected to the input end of the fan through an air intake box provided on one side.

[0008] Preferably, the positioning mechanism includes a lifting disc, a semi-threaded sleeve, a clamp, a guide groove and a pressing patch. The outer side of the lifting disc is provided with a guide groove in a cross shape, the outer side of the guide groove is connected to the bottom end of the clamp, the outer side of the lifting disc is provided with a semi-threaded sleeve in a rectangular shape, and the outer side of the semi-threaded sleeve is connected with a pressing patch.

[0009] Preferably, the lifting disc is connected to the outer side of the pressing patch through a semi-threaded sleeve rod distributed in a rectangular shape.

[0010] Preferably, the lifting tray is connected to the outer side of the adsorption part through rectangularly distributed clamps.

[0011] Compared with the prior art, the utility model has the following advantages:

[0012] 1. The outside air is sucked into the air intake box through the fan, and the air intake box is used to cool the inhaled air and then cool the inside of the adsorption tank to keep the oil and gas between 0-20 degrees Celsius. The cooled oil and gas can prevent the problem of large internal circulation of light components during subsequent treatment, thereby reducing the difficulty of obtaining lower concentration exhaust gas and eliminating the problem of high temperature rise in the adsorption bed hot spot.

[0013] 2. The pressing patch is vertically guided by the semi-threaded sleeve rods distributed in a rectangular shape, which makes it easy to vertically position the adsorption parts of different sizes, and to quickly disassemble and replace the adsorption parts, saving the flexibility of disassembly and replacement of the adsorption parts. The fixture is positioned by the guide provided at the bottom, and is clamped and slid on the outside of the guide groove, which facilitates the clamping and positioning of both sides of the adsorption parts of different diameters.

[0022] like Figures 1 to 5 As shown, a skid-mounted oil and gas recovery adsorption tank includes an adsorption tank body 1, a cooling chamber 15 and an adsorption part 16. The top of the adsorption tank body 1 is provided with a feed pipe 2, and the bottom of the adsorption tank body 1 is provided with a discharge pipe 3. A cooling mechanism 4 is provided on one side of the adsorption tank body 1. The cooling mechanism 4 cools the external air and then injects it into the cooling chamber 15, thereby accelerating the cooling and adsorption speed of the oil and gas through the cooling chamber 15. A positioning mechanism 9 is provided inside the adsorption tank body 1, and the positioning mechanism 9 clamps the adsorption parts 16 of different sizes to meet the adsorption of different quantities of oil and gas, and at the same time facilitates the disassembly and replacement of the positioning mechanism 9 and the adsorption part 16.

[0023] In this embodiment, the cooling mechanism 4 includes an air intake pipe 5, an air intake box 6, a fan 7, a semiconductor refrigeration component 8 and a cooling chamber 15. The bottom end of the air intake pipe 5 is connected to the top of the air intake box 6, and one side of the air intake box 6 is connected to the output end of the fan 7. One side of the adsorption tank body 1 is fitted with the semiconductor refrigeration component 8, and the other side of the air intake pipe 5 is connected to the outside of the adsorption tank body 1. The cooling chamber 15 is distributed in a ring shape inside the adsorption tank body 1.

[0024] In this embodiment, the adsorption tank body 1 is connected to the input end of the fan 7 through the air inlet box 6 provided on one side. After the air is circulated and injected to cool the interior of the adsorption tank body 1, a circulatory cooling treatment is performed.

[0025] In this embodiment, the positioning mechanism 9 includes a lifting disc 10, a semi-threaded sleeve 11, a clamp 12, a guide groove 13 and a pressing patch 14. The outer side of the lifting disc 10 is cross-shaped with a guide groove 13, and the outer side of the guide groove 13 is connected to the bottom end of the clamp 12. The outer side of the lifting disc 10 is rectangularly distributed with a semi-threaded sleeve 11, and the outer side of the semi-threaded sleeve 11 is connected with a pressing patch 14, and the top of the adsorption part 16 is positioned by the pressing patch 14.

[0026] In this embodiment, the lifting plate 10 is connected to the outer side of the pressing patch 14 through a rectangularly distributed semi-threaded sleeve rod 11, and the semi-threaded sleeve rod 11 is connected to the outer side of the pressing patch 14.

[0027] In this embodiment, the lifting tray 10 is connected to the outer side of the adsorption part 16 through rectangularly distributed clamps 12, and the clamps 12 are used to clamp and position the adsorption parts 16 of different sizes.

[0028] The actual application of this skid-mounted oil and gas recovery adsorption tank includes the following work contents:

[0029] Step 1: During use, first remove the corresponding equipment of the positioning mechanism 9 from the interior of the adsorption tank body 1. The operator places the adsorption part 16 on the surface of the lifting plate body 10, then pulls the clamp 12, and slides the clamp 12 on the outside of the guide groove 13, thereby clamping and positioning the bottom end of the adsorption part 16 through the four groups of clamps 12. The bolts are inserted into the clamps 12 and the outside of the lifting plate body 10 to complete the clamping and positioning of the adsorption part 16.

[0030] Step 2: According to the height of the adsorption part 16, pull the pressing patch 14 so that the pressing patch 14 drops vertically on the outside of the semi-threaded sleeve 11, so that the pressing patch 14 presses the top of the adsorption part 16, and rotates and locks the outside of the semi-threaded sleeve 11 through the nut to prevent the top of the adsorption part 16 from shaking, and then connect the tail end of the feeding pipe 2 to the top of the adsorption part 16;

[0031] Step 3: Then, the semiconductor refrigeration assembly 8 is turned on to cool the outside of the air intake box 6 and the adsorption tank 1, and the fan 7 is turned on to introduce the external air into the interior of the adsorption tank 1. After the semiconductor refrigeration assembly 8 cools the inhaled air, the cooled air is injected into the cooling chamber 15 through the air intake pipe 5, and the interior of the adsorption tank 1 is circulated and cooled;

[0032] Step 4: Use the feed pipe 2 to inject oil and gas into the adsorption part 16. The activated carbon adsorption layer in the adsorption part 16 can adsorb the remaining hydrocarbon components in the oil and gas. At the same time, the cooling chamber 15 liquefies the filtered oil and gas, and then the condensed oil is directly discharged from the adsorption tank body 1 through the discharge pipe 3 set at the bottom.

[0033] Therefore, the embodiments disclosed above are only illustrative in all respects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
