[0002] A centrifugal compressor unit is a device with a structure and operating principle similar to a centrifugal blower, but it is always multi-stage and can obtain a higher pressure on the gas. It has the characteristics of large processing capacity and high efficiency. Centrifugal compressors are widely used in various process flows to transport air, various process gases or mixed gases and increase their pressure.

The traditional method is to install a filter on each machine for filtering, but a single filter can only play a simple primary filtration, and the filtering effect is general. The oil smoke content in the filtered gas is still relatively high, and the gas discharged into the atmosphere will still cause environmental pollution. Therefore, the market urgently needs to develop an oil smoke separation device for centrifugal compressor units to help people solve the existing problems. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] See also Figure 1-4The utility model provides an embodiment of an oil fume separation device for a centrifugal compressor unit, comprising a separation box 3, an air intake box 2 is fixedly installed on one side above the separation box 3, and a main pipe 1 is fixedly installed on one side of the air intake box 2. The main pipe 1 is used to connect the exhaust pipes of the bearing seats and oil outlets of multiple centrifugal compressor units and the coupling. A fan 5 is fixedly installed inside the air intake box 2, and the air inlet end of the fan 5 is connected to the main pipe 1, and the air outlet end of the fan 5 is fixedly installed with a delivery pipe 16. An oil mist separator 12 is fixedly installed above the separation box 3. The oil mist separator 12 is a centrifugal oil mist separator. One end of the delivery pipe 16 extends into the interior of the separation box 3 and is fixedly connected to the oil mist separator 12. A reflux mechanism is provided on one side of the oil mist separator 12. The reflux mechanism includes a delivery pipe 2 16, a gas composition online analyzer 17, an exhaust pipe 18 and a reflux pipe 19. The setting of the gas composition online analyzer 17 can detect and analyze the gas in the delivery pipe 2 16.

[0024] When in use, by connecting the main pipeline 1 with the exhaust pipes of multiple centrifugal compressor units and equipping with a fan 5, the oil smoke generated by multiple units can be centrally extracted and transported, so that the oil smoke can be stably and continuously sent to the separation box 3, and then the oil droplets in the oil smoke can be effectively captured by the efficient separation ability of the centrifugal oil mist separator, which greatly reduces the oil smoke content in the exhaust gas. At the same time, through the setting of the reflux mechanism and the introduction of the gas composition online analyzer 17, the separated gas can be monitored in real time to ensure the emission quality. When the oil smoke content in the gas exceeds the standard, the gas is returned to the delivery pipe 6 through the reflux pipe 19 for re-separation, which increases practicality.

[0025] Furthermore, one end of the delivery pipe 16 is fixedly connected to the oil mist separator 12, the gas composition online analyzer 17 is fixedly installed above the delivery pipe 16, the return pipe 19 is fixedly installed above the delivery pipe 16, and one end of the return pipe 19 passes through the interior of the separation box 3 and is fixedly connected to the delivery pipe 1 6, the other end of the delivery pipe 16 is fixedly installed with an exhaust pipe 18, one end of the exhaust pipe 18 passes through the interior of the separation box 3, and the outside of the exhaust pipe 18 and the return pipe 19 are fixedly installed with a solenoid valve 20. The setting of the solenoid valve 20 facilitates the intelligent control of gas emission and reflux according to the detection results of the gas composition online analyzer 17, thereby realizing the regulation of oil fume treatment, which not only improves the treatment efficiency, but also reduces manual intervention and reduces operating costs.

The combination of the oil outlet pipe 13, the oil suction station 14 and the oil drain pipe 15 realizes the centralized collection and treatment of the separated oil, thereby increasing practicality.

[0027] Furthermore, a heat exchange sleeve 7 is fixedly installed on the outer side of the delivery pipe 6, a water inlet pipe 8 is fixedly installed on one side above the heat exchange sleeve 7, and the water inlet pipe 8 extends to the top of the air intake box 2, and the water inlet pipe 8 is externally connected to a water pumping device, a water outlet pipe 9 is fixedly installed on the other side below the heat exchange sleeve 7, and the water outlet pipe 9 extends to the rear end of the air intake box 2, a heat insulation pad 10 is fixedly installed on the inner side of the heat exchange sleeve 7, and a spiral ring sheet 11 is provided inside the heat exchange sleeve 7 along the outer side of the delivery pipe 6.

Air-permeable grilles 22 are fixedly installed at the front ends of the air intake box 2 and the separation box 3, which facilitates heat dissipation inside the air intake box 2 and the separation box 3 and increases practicality.

[0029] Working principle: When in use, the exhaust pipes of multiple centrifugal compressor units are connected through the main pipe 1, and the suction force generated by the fan 5 is used to stably and continuously extract the oil smoke generated by the unit and transport it to the inside of the separation box 3. In the separation box 3, the oil smoke passes through the efficient separation effect of the centrifugal oil mist separator 12, and the oil droplets are effectively captured and flow into the oil suction station 14 along the oil outlet pipe 13, and finally discharged to the external compressor oil tank through the oil discharge pipe 15 for recycling. At the same time, the separated gas is transported through the delivery pipe 2 16 and detected by the gas composition online analyzer 17. If the oil smoke content exceeds the standard, the solenoid valve controls the reflux pipe 19 to open, and the gas is returned to the delivery pipe 1 6 for separation again until it meets the standard and is discharged through the exhaust pipe.
