Embodiment Construction
[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0022] Such as Figure 1-Figure 5 As shown, an oil gas environmental protection recovery device includes an exhaust pipe 1, and the exhaust pipe 1 is installed in compressors, oil storage tanks and other equipment. The top of the exhaust pipe 1 is provided with an exhaust port 2, and the top of the exhaust port 2 is covered with a breathing valve 3. The breathing valve 3 is provided with a valve port 4 for oil and gas discharge. The breathing valve 3 is used for the discharge of oil and gas, and prevents The outside air flows back into the exhaust pipe 1. The outside of the breathing valve 3 is also covered with a condensation recovery device. The condensation recovery device includes a dust cover 5, an oil collection part 6 and an oil return pipe 7. The dust cover 5 covers the collection Above the oil part 6, the oil collecting part 6 is wel...

A disclosed environment-friendly oil gas recovery device comprises an exhaust pipe, an exhaust port is formed in the upper portion of the exhaust pipe, a breather valve covers the upper portion of the exhaust port, a valve port allowing oil gas to be discharged is formed in the breather valve, the outer side of the breather valve is further covered with a condensation recovery device, and the condensation recovery device comprises a dustproof cover, an oil collecting part and an oil return pipe. The dustproof cover covers the oil collecting part, the oil collecting part is arranged on the peripheral side of the breather valve, an exhaust hole is formed in the upper portion of the oil collecting part, and the oil return pipe is connected with the bottom of the oil collecting part and the exhaust pipe. Oil gas sequentially enters the oil collecting part through the exhaust port to be cooled and liquefied, liquefied oil enters the exhaust pipe through the oil return pipe, common air is exhausted to the outside through the exhaust port, and the oil gas recovery device has the advantages that oil gas emission is greatly reduced, and the outside environment is protected.
Description
technical field [0001] The invention relates to the field of chemical industry, in particular to an oil gas environmental recovery recovery device. Background technique [0002] Compressors, pumps, fans and other rotating equipment are indispensable in modern petrochemical installations, providing the necessary power source for the medium conveyed in production. [0003] Take the reciprocating compressor as an example. At present, the lubricating oil in the crankcase of the compressor is heated by the friction temperature of the crankshaft during operation to produce oil gas, which is discharged into the atmosphere through the breathing valve on the top of the crankcase, causing pollution to the surrounding environment; the oil condensed in the oil gas The drops flow along the pipe wall to the top cover of the crankcase and the surrounding ground, which increases the workload of oil pollution treatment and also causes a waste of lubricating oil; random venting of oil and gas...
