Description

Technical Field

[0001] The utility model relates to the field of compressor unit technical processing, in particular to a compressor unit oil fume separation, recovery and utilization system. Background Art

[0002] The lubricating oil system of a large centrifugal compressor unit will generate a large amount of oil smoke due to heat during operation. The oil smoke will be discharged through the oil tank and bearing box exhaust pipes. The exhausted oil smoke directly enters the atmosphere and has a great impact on environmental pollution. In addition, during the process of discharging a large amount of oil smoke, a part of the lubricating oil will be discharged in the form of oil mist or oil droplets in the form of gas-liquid entrainment. The discharged lubricating oil flows to equipment parts and the ground and cannot be recycled, making on-site sanitation and cleaning difficult. In addition, it causes pollution to the environment and soil. With the long-term operation of the device, it has a great impact in terms of waste of lubricating oil costs, environmental pollution and personal injury, which to a large extent restricts the safe, efficient and energy-saving operation of the device. Utility Model Content

[0003] The utility model provides a compressor unit oil fume separation, recovery and utilization system, which can recover the lubricating oil wasted due to gas-liquid entrainment in oil fume emission, and improve the environmental pollution caused by oil fume discharge to the atmosphere and oil droplets to the ground soil.

[0004] The specific plan is as follows:

[0005] A compressor unit oil fume separation, recovery and utilization system includes a compressor unit connected to a lubricating oil tank via an oil pump. The compressor unit and the lubricating oil tank are connected to the lower part of an oil fume separator via an oil fume exhaust pipe A and an oil fume exhaust pipe B, respectively. The top of the oil fume separator is connected to an oil fume treatment device, and the bottom is connected to the lubricating oil tank via a lubricating oil recovery and treatment pipeline.

[0006] The lubricating oil recovery and processing pipeline includes gate valve A, filter, and gate valve B connected in sequence from top to bottom; the lubricating oil separated by the oil fume separator passes through gate valve A, is filtered by the filter, and then flows back to the lubricating oil tank through gate valve B.

[0007] A sight glass is also provided below the gate valve B in the lubricating oil recovery and treatment pipeline to facilitate observation of the oil return condition in the lubricating oil recovery and treatment pipeline.

[0008] The oil fume treatment device comprises an ejector connected to an oil fume separator, and the ejector is connected to a combustion device via a check valve to realize combustion utilization of the oil fume.

[0009] The ejector is an air ejector and is connected to a nitrogen pipeline; nitrogen, as an inert gas, can protect the compressor unit components from oxidation, and is safe and reliable.

[0010] The ejector is also connected to the smoke exhaust pipe through a ball valve to prevent the smoke exhaust pipeline from being reserved when the combustion device is overhauled.

[0011] An oil removal net is provided inside the oil fume separator. When oil droplets or oil stains in the oil fume come into contact with the oil removal net, they will adhere to the oil removal net and will drip to the bottom of the oil fume separator after accumulating to a certain extent.

[0012] The utility model adopts an ejector vacuuming method. During the operation of the compressor unit, all the exhausted oil smoke can be discharged through the ejector to the combustion device for combustion, thereby solving the problem of a large amount of oil smoke being discharged into the atmosphere and polluting the environment. At the same time, the separated lubricating oil is recovered, realizing resource recycling and reuse. The use of inert gas nitrogen as a carrier is also safe and reliable.
