Description

Technical Field

[0001] This utility model relates to the technical field of oil and gas recovery, and specifically to a skid-mounted oil and gas recovery storage tank. Background Technology

[0002] Oil and gas recovery refers to the collection of volatile oil and gas from oil depots through main pipelines, followed by condensation processes to transform the oil and gas from a gaseous state into a liquid state, and then back into gasoline, thereby achieving the purpose of recycling. Recovery storage tanks are devices used to recover and store the liquid gasoline. Through recovery storage tanks, the recovered liquid oil and gas can be stored effectively.

[0003] However, when unloading oil from the recovery storage tank, because the recovery storage tank is horizontally located in the underground space, the recovery storage tank cannot completely unload the fuel. The prolonged retention of some recovered oil will lead to some new recovery. At the same time, after a certain period of accumulation in the storage tank, due to the increase in temperature and heat conduction between the storage tank, the oil in the storage tank will rapidly re-vaporize due to the excessive temperature, resulting in excessively high gas pressure inside the oil storage tank, which poses a serious safety hazard. Summary of the Invention

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

[0005] A skid-mounted oil and gas recovery storage tank includes a tank body, a pressure relief valve, and a hydraulic cylinder. The pressure relief valve and a pressure sensor are located directly above the tank body. A tilting mechanism is located on the outer side of the tank body, tilting one side of the tank body to facilitate the direct discharge of internal liquid and prevent residual oil from accumulating and deteriorating. A water cooling mechanism is located directly below the tank body, which can uniformly absorb the internal temperature of the tank from bottom to top, thus achieving the purpose of stabilizing and cooling the internal temperature of the tank.

[0006] Preferably, the tilting mechanism includes a discharge pipe fitting, a first clamp, a second clamp, and a hydraulic cylinder. The discharge pipe fitting is installed on one side of the tank body. The first clamp is connected to the outer side of the tank body, and the second clamp is connected to the outer side of the tank body. The hydraulic cylinder is connected directly below the second clamp.

[0007] Preferably, the hydraulic cylinder is connected to the outside of the tank body via a clamp provided at its output end.

[0008] Preferably, the water-cooling mechanism includes a liquid storage tank, a liquid injection hose, a return pipe, a circulation pump, a cooling chamber, and heat-insulating packing. The circulation pump input is located on one side of the liquid storage tank, and the output of the circulation pump is connected to one end of the liquid injection hose. The other end of the liquid injection hose is connected to the cooling chamber. The other side of the cooling chamber is connected to one end of the return pipe, and the other end of the return pipe is connected to the cooling chamber. The cooling chamber is located inside the liquid storage tank, and heat-insulating packing is installed inside the cooling chamber.

[0009] Preferably, the circulating pump is connected to the interior of the cooling chamber via a liquid injection hose connected to its output end.

[0010] Preferably, the tank body is connected to the heat-insulating packing side through an internally provided cooling chamber.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] 1. During the adjustment process, the two sides of the tank are positioned by clamp one and clamp two. Clamp two is axially connected to the outside of the tank and clamp one drives the bottom of the tank to be vertically supported and raised and lowered. Then, the angle of the tank can be flexibly adjusted according to the usage requirements, so as to facilitate the complete emptying and cleaning of the oil inside the tank.

[0013] 2. The water-cooled circulating cooling system removes heat from the inside of the neutralization tank, ensuring a normal internal temperature and preventing excessive pressure that could lead to tank explosion. This improves the safety of the device and extends its service life. Additionally, the outer side of the tank is insulated with heat-insulating packing to prevent external temperature from directly transferring heat to the internal liquid and causing continuous pressure build-up.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] like Figures 1 to 4 As shown, a skid-mounted oil and gas recovery storage tank includes a tank body 1, a pressure relief valve 2, and a hydraulic cylinder 8. The pressure relief valve 2 is located directly above the tank body 1, and a pressure sensor 3 is located directly above the tank body 1. A tilting mechanism 9 is located on the outer side of the tank body 1, which tilts one side of the tank body 1 to facilitate the direct discharge of liquid inside the tank body 1 and prevent residual oil from accumulating and causing deterioration. A water cooling mechanism 10 is located directly below the tank body 1, which can uniformly absorb the temperature inside the tank body 1 from bottom to top, thus achieving the purpose of stabilizing and cooling the temperature inside the tank body 1.

[0022] In this embodiment, the tilting mechanism 9 includes a discharge pipe 4, a first clamp 5, a second clamp 6, and a hydraulic cylinder 8. The discharge pipe 4 is installed on one side of the tank body 1. The first clamp 5 is connected to the outer side of the tank body 1, and the second clamp 6 is connected to the other outer side of the tank body 1. The output end of the hydraulic cylinder 8 is connected directly below the second clamp 6. The height of the second clamp 6 is adjusted by the hydraulic cylinder 8, so that the tank body 1 is tilted.

[0023] In this embodiment, the hydraulic cylinder 8 is connected to the outside of the tank body 1 through a clamp 5 at its output end. The clamp 5 positions one side of the tank body 1, thereby adjusting and controlling the angle of the tank body 1.

[0024] In this embodiment, the water cooling mechanism 10 includes a liquid storage tank 11, a liquid injection hose 7, a return pipe 12, a circulation pump 13, a cooling chamber 14, and heat insulation packing 15. The input end of the circulation pump 13 is provided on one side of the liquid storage tank 11, and the output end of the circulation pump 13 is connected to one end of the liquid injection hose 7. The other end of the liquid injection hose 7 is connected to the cooling chamber 14. The other side of the cooling chamber 14 is connected to one end of the return pipe 12, and the other end of the return pipe 12 is connected to the cooling chamber 14. The cooling chamber 14 is opened inside the liquid storage tank 11, and the interior of the cooling chamber 14 is provided with heat insulation packing 15. The heat insulation packing 15 isolates heat and prevents heat accumulation from causing an increase in liquid vaporization pressure.

[0025] In this embodiment, the circulating pump 13 is connected to the inside of the cooling chamber 14 through the liquid injection hose 7 connected to the output end. The liquid circulating inside the cooling chamber 14 carries away the heat transferred from the surrounding environment, thus preventing the internal pressure of the tank 1 from increasing.

[0026] In this embodiment, the tank body 1 is connected to one side of the heat insulation packing 15 through the internally provided cooling chamber 14, and the outer end of the cooling chamber 14 of the tank body 1 is isolated by the columnar heat insulation packing 15.

[0027] In practical applications, this skid-mounted oil and gas recovery storage tank includes the following tasks:

[0028] Step 1: During use, firstly, the coolant is directly injected into the inside of the storage tank 11. Then, the circulation pump 13, which is set on one side of the storage tank 11, is opened. The circulation pump 13 is used to directly inject the liquid into the cooling chamber 14 set inside the tank 1. The liquid circulating inside the cooling chamber 14 carries away the heat from the outside of the tank 1. The heat insulation packing 15 is used to isolate the heat from the outside, preventing the heat from the outside from being directly transferred to the inside of the tank 1, which would cause the internal pressure of the tank 1 to rise.

[0029] Step 2: At the same time, the internal pressure of tank 1 is monitored by pressure sensor 3. When the circulating liquid cannot control the increase of internal pressure of tank 1, the internal pressure of tank 1 is relieved by pressure relief valve 2 set at the top of tank 1, and a certain amount of medium is quickly discharged to reduce the working pressure.

[0030] Step 3: When it is necessary to discharge the liquid inside the tank 1, first open the discharge pipe 4 to discharge the oil inside the tank 1. Then, open the hydraulic cylinder 8 to vertically lift the clamp 6. At the same time, the clamp 5 on the other side rotates with the outside of the tank 1, thereby tilting one side of the tank 1 to facilitate the direct emptying of the remaining liquid inside the tank 1.

[0031] Therefore, the above-disclosed embodiments are merely illustrative in all respects and are not the only ones. All modifications within the scope of this utility model or its equivalents are included in this utility model.
