Description

Petroleum and natural gas recovery device Technical Field The utility model relates to the technical field of winding devices, in particular to an oil and natural gas recovery device. Background In the petroleum exploitation process, natural gas is released, because the natural gas just exploited contains more impurities, the natural gas is directly used as fuel to cause environmental pollution, equipment loss and resource waste are also caused, so the natural gas is required to be pretreated and purified before being used as fuel, and dust removal, sulfur removal and carbon removal are usually included, and the exploited natural gas is required to be treated by a recovery treatment device, but natural gas leakage easily occurs in the treatment process, and explosion easily occurs in serious cases, so that resource loss and casualties are caused; As in the prior art, the patent with the authorized bulletin number of CN221988482U discloses a petroleum and natural gas recovery device, the petroleum and natural gas recovery device detects the concentration of natural gas in a sealed leak-proof shell through an alarm, alarms before the concentration rises, a worker can stop the operation of the device in time before firing, overhaul equipment avoids expansion loss, dust removing, carbon removing and sulfur removing parts in the device are complete, the damage to equipment when the natural gas is used is reduced, and meanwhile, the natural gas is subjected to gas-liquid separation, the natural gas is recovered in a classified way, so that the cost of secondary separation of the natural gas in the later period is reduced; However, when the natural gas leaks, the natural gas cannot be discharged from the inside of the leak-proof shell, and the operator can stop the operation of the device in time, but the natural gas leaked from the leak-proof shell cannot be discharged in the process of overhauling the operator, so that the situation of explosion is easy to occur and casualties are easy to cause when the leak-proof shell is opened, and the petroleum and natural gas recovery device is designed to solve the problems.
