Description

Technical Field

[0001] This utility model relates to the field of winding device technology, and in particular to an oil and gas recovery device. Background Technology

[0002] During oil extraction, natural gas is released. Since freshly extracted natural gas usually contains a lot of impurities, using it directly as fuel will cause environmental pollution, equipment wear and tear, and waste of resources. Therefore, natural gas needs to be pre-treated and purified before it can be used as fuel. This usually includes dust removal, desulfurization, and decarbonization. Therefore, recovery and treatment devices are needed to process the extracted natural gas. However, natural gas leaks are prone to occur during the treatment process, and in severe cases, explosions can occur, leading to resource losses and casualties.

[0003] For example, in the prior art, the patent with authorization announcement number CN221988482U discloses an oil and gas recovery device. This oil and gas recovery device uses an alarm to detect the concentration of natural gas inside the sealed, leak-proof outer shell. It will sound an alarm before the concentration rises, so that the staff can stop the operation of the device in time before fire, repair the equipment and avoid further damage. The device has complete dust removal, carbon removal and sulfur removal components, which reduces the damage to the equipment when natural gas is used. At the same time, it performs gas-liquid separation of natural gas and recovers natural gas in categories, reducing the cost of secondary separation of natural gas in the later stage.

[0004] However, when the natural gas recovery device leaks, the natural gas is trapped inside the leak-proof casing and cannot be discharged. Although the staff can stop the operation of the device in time, the natural gas leaking inside the leak-proof casing cannot be discharged. During the maintenance process, if the leak-proof casing is opened, an explosion may occur, which may cause casualties. Therefore, an oil and gas recovery device is designed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the above-mentioned background technology and to propose an oil and gas recovery device.

[0006] The technical problem to be solved by this utility model is to provide an oil and gas recovery device, which solves the problem that existing natural gas recovery devices are prone to leakage and explosion, which can easily cause casualties.

[0007] This utility model provides an oil and gas recovery device, including an explosion-proof box, an inspection door, an air inlet pipe, a gas purification box, a connecting pipe, and a high-pressure gas-liquid separator. The inspection door is hinged to the left end of the outer surface of the explosion-proof box. An air inlet pipe penetrates the left side of the explosion-proof box, and the gas purification box is inserted through the end of the air inlet pipe. A connecting pipe penetrates the right end of the gas purification box, and a high-pressure gas-liquid separator is inserted through the right end of the connecting pipe. An exhaust pipe penetrates the top of the high-pressure gas-liquid separator, and a drain pipe penetrates the bottom of the high-pressure gas-liquid separator. A ventilation pipe penetrates the upper right side of the explosion-proof box, and an exhaust fan is installed inside the ventilation pipe. A natural gas solubility detector is fixedly installed at the top inside the ventilation pipe. An alarm is fixedly installed on the right end of the upper surface of the explosion-proof box.

[0008] Preferably, the natural gas solubility detector is equipped with a controller, and the controller is electrically connected to an alarm.

[0009] Preferably, the ventilation duct is connected to the indoor exhaust duct.

[0010] Preferably, the gas purification box includes a sealed door, inverted concave blocks, a sulfur adsorption mesh box, a carbon adsorption mesh box, and a dehydration mesh box. The sealed door is rotatably mounted on the outer surface of the gas purification box via a hinge. Three inverted concave blocks are fixedly mounted on the upper and lower sides of the inner side of the gas purification box. The sulfur adsorption mesh box, carbon adsorption mesh box, and dehydration mesh box are sequentially embedded between the upper and lower inverted concave blocks from left to right.

[0011] Preferably, the sulfur adsorption mesh box is filled with sulfur adsorbent, the carbon adsorption mesh box is filled with carbon adsorbent, and the dehydration mesh box is filled with synthetic zeolite.

[0012] Preferably, a sealing rubber ring is embedded on the outer surface of the gas purification box, and the sealing door is tightly attached to the rubber sealing ring when closed.

[0013] Preferably, the air intake pipe is in the shape of an inverted L, and a sealing cap is threaded to the bottom of the air intake pipe. A through pipe is provided through the side of the air intake pipe, and the right end of the through pipe is provided through the gas purification box. A dust filter is fixedly provided at the left end of the inside of the through pipe.

[0014] Preferably, the bottom of the intake pipe is at a lower horizontal height than the through pipe.

[0015] Compared with the prior art, this utility model has at least the following beneficial effects:

[0016] 1. This utility model, equipped with a ventilation pipe, exhaust fan, natural gas solubility detector, and alarm, allows natural gas to be purified in the natural gas recovery process. The purified natural gas enters the gas purification chamber through the inlet pipe, undergoes gas-liquid separation in the high-pressure gas-liquid separator, and is then discharged through the exhaust pipe for collection. When a natural gas leak occurs, the natural gas solubility detector detects excessively high solubility and triggers the alarm via the controller. This allows staff to promptly shut down the equipment to prevent excessive leakage and reduce environmental pollution. Simultaneously, the controller activates the exhaust fan to expel the leaked natural gas, preventing its accumulation in the explosion-proof enclosure and facilitating timely equipment maintenance.

[0017] 2. This utility model incorporates a gas purification box. After natural gas enters the gas purification box, sulfur-containing gases in the natural gas are adsorbed by the sulfur adsorbent in the sulfur adsorption mesh box, and carbon powder in the carbon adsorption mesh box is adsorbed by the carbon adsorbent in the natural gas. Moisture in the natural gas is adsorbed by synthetic zeolite, ensuring the purity of the natural gas and reducing air pollution during subsequent combustion. Furthermore, opening the sealed door allows for easy removal of the sulfur adsorption mesh box, carbon adsorption mesh box, and dehydration mesh box to replace the sulfur adsorbent, carbon adsorbent, and synthetic zeolite inside, ensuring the continuity of natural gas recovery.

[0018] 3. This utility model features an air inlet pipe. When natural gas enters through the inlet pipe, a dust filter blocks dust from the natural gas. The dust and water fall to the sealing cap at the bottom of the inlet pipe and enter the gas purification chamber. The filtered natural gas can then enter the gas purification chamber through a through-pipe for further purification, achieving the effect of removing dust from the natural gas. This prevents dust from affecting the purification effect of the gas purification chamber on the natural gas. When it is necessary to dispose of the collected dust, simply turn off the equipment, unscrew the sealing cap, and the dust can be discharged from the bottom of the inlet pipe. The operation is simple and convenient. Attached Figure Description

[0027] Example:

[0028] like Figures 1-5 As shown, an embodiment of this utility model provides an oil and gas recovery device, including an explosion-proof box 1, an inspection door 2, an air inlet pipe 3, a gas purification box 4, a connecting pipe 5, and a high-pressure gas-liquid separator 6. The inspection door 2 is rotatably mounted on the left side of the outer surface of the explosion-proof box 1 via a hinge. The air inlet pipe 3 is inserted through the left side of the explosion-proof box 1. The gas purification box 4 is inserted through the end of the air inlet pipe 3. The connecting pipe 5 is inserted through the right end of the gas purification box 4. The high-pressure gas-liquid separator 6 is inserted through the right end of the connecting pipe 5. The exhaust pipe 7 is inserted through the top of the high-pressure gas-liquid separator 6. The drain pipe 8 is inserted through the bottom of the high-pressure gas-liquid separator 6. The ventilation pipe 9 is inserted through the upper right side of the explosion-proof box 1. An exhaust fan 10 is installed inside the ventilation pipe 9. A natural gas solubility detector 11 is fixedly mounted on the top inside the ventilation pipe 9. An alarm 12 is fixedly mounted on the right side of the upper surface of the explosion-proof box 1.

[0029] Equipped with a ventilation pipe 9, an exhaust fan 10, a natural gas solubility detector 11, and an alarm 12, the natural gas is purified in the gas purification box 4 through the inlet pipe 3 during the natural gas recovery process. The purified natural gas then enters the high-pressure gas-liquid separator 6 for gas-liquid separation. The natural gas is discharged through the exhaust pipe 7 for collection. When a natural gas leak occurs, the natural gas solubility detector 11 detects that the natural gas solubility is too high and controls the alarm 12 to sound an alarm through the controller. The staff can then shut down the equipment in time to prevent excessive leakage of gas and reduce environmental pollution. At the same time, the controller controls the exhaust fan 10 to turn on and discharge the leaked natural gas, preventing the natural gas from accumulating in the explosion-proof box 1 and facilitating timely maintenance by the staff.

[0030] In this embodiment, a controller is provided on the natural gas solubility detector 11, and the controller is electrically connected to the alarm 12, so that the controller can control the alarm to sound.

[0031] In this embodiment, the ventilation pipe 9 is connected to the indoor exhaust pipe, so that the ventilation pipe 9 can discharge the leaked gas outdoors through the exhaust pipe.

[0032] In this embodiment, the gas purification box 4 includes a sealing door 401, an inverted concave block 402, a sulfur adsorption mesh box 403, a carbon adsorption mesh box 404, and a dehydration mesh box 405. The sealing door 401 is rotatably provided on the outer surface of the gas purification box 4 via a hinge. Three inverted concave blocks 402 are fixedly provided on the upper and lower sides of the inner side of the gas purification box 4. The sulfur adsorption mesh box 403, the carbon adsorption mesh box 404, and the dehydration mesh box 405 are sequentially embedded between the upper and lower inverted concave blocks 402 from left to right.

[0033] In this embodiment, the sulfur adsorption mesh box 403 is filled with sulfur adsorbent, the carbon adsorption mesh box 404 is filled with carbon adsorbent, and the dehydration mesh box 405 is filled with synthetic zeolite.

[0034] In this embodiment, a sealing rubber ring is embedded on the outer surface of the gas purification box 4, and the sealing door 401 is tightly attached to the rubber sealing ring when closed, ensuring the airtightness of the gas purification box 4.

[0035] By setting up a gas purification box 4, after natural gas enters the gas purification box 4, the sulfur-containing gases in the natural gas are adsorbed by the sulfur adsorbent in the sulfur adsorption mesh box 403, and the carbon adsorbent in the carbon adsorption mesh box 404 adsorbs the carbon powder in the natural gas. The moisture in the natural gas is adsorbed by artificial synthetic zeolite, which ensures the purity of the natural gas and reduces the air pollution during the subsequent combustion of natural gas. Moreover, by opening the sealed door 401, it is convenient to take out the sulfur adsorption mesh box 403, carbon adsorption mesh box 404 and dehydration mesh box 405 to replace the sulfur adsorbent, carbon adsorbent and artificial synthetic zeolite inside, ensuring the continuity of natural gas recovery.

[0036] In this embodiment, the air intake pipe 3 is inverted L shape, and the bottom of the air intake pipe 3 is threadedly connected to a sealing cap 301. A through pipe 302 is provided through the side of the air intake pipe 3. The right end of the through pipe 302 is provided through the gas purification box 4. A dust filter 303 is fixedly provided inside the left end of the through pipe 302.

[0037] In this embodiment, the bottom horizontal height of the intake pipe 3 is lower than the horizontal height of the through pipe 302.

[0038] With the intake pipe 3 in place, when natural gas enters through the intake pipe 3, the dust filter 303 blocks the dust in the natural gas. The dust and water fall to the sealing cap 301 at the bottom of the intake pipe 3 and enter the handpiece. The filtered natural gas can then enter the gas purification box 4 through the through pipe 302 for purification, achieving the effect of removing dust from the natural gas and preventing dust from affecting the purification effect of the gas purification box 4 on the natural gas. When it is necessary to deal with the collected dust, the equipment can be turned off, the sealing cap 301 can be unscrewed, and the dust can be discharged from the bottom of the intake pipe 3. The operation is simple and convenient.

[0039] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these should also be considered within the scope of protection of this utility model. These will not affect the implementation effect of this utility model or the practicality of the patent.
