Abstract

The invention discloses a process and a device for purifying oil-containing tail gas with good purification effect. The process comprises that: the oil-containing tail gas is absorbed from an air inlet of the purification device, subjected to oil removal, filtration and purification by an indirect cooling spiral, and exhausted from an exhaust port. The purification device comprises a purification channel between the air inlet and the exhaust port; the purification channel is provided with an indirect cooling and separation device, a filter, a differential pressure alarm, an air suction fan, and the like; and the indirect cooling and separation device is preferably provided with a tail gas channel and a cooling medium channel with spiral trend. The purification device has compact structure, small volume, running air resistance of less than 4,000 Pa, high purification efficiency, and simple operation, can effectively recycle lubricant, reduce environmental pollution, and can be used as matched equipment of large gas compressors and turbines.

Description

technical field [0001] The invention relates to a process and equipment for separating oily tail gas, in particular to a process and device for purifying oily tail gas of a large centrifugal gas compressor or turbine equipment. Background technique [0002] At present, a large amount of exhaust gas is produced during the working process of large-scale gas compression equipment and turbine equipment, and its temperature is generally 40-70°C. The exhaust gas will not pollute the environment. At the same time, in order to recycle the lubricating oil, the exhaust gas purification device is usually used to treat the oily exhaust gas before it is discharged. [0003] The existing oily tail gas purification processes mainly include the following types. [0004] Water mist spraying method: The tail gas sucked by the fan enters the water mist spray purifier, and is washed by water mist to purify the oily tail gas, and the oil enters the water and is discharged to the waste water poo...
