Low-noise rotary capture absorption type oil-gas separator

Abstract

The invention discloses a low-noise rotary capture adsorption type oil-gas separator, which includes a casing, a driven shaft is installed at one end of the casing, and a turntable is arranged at the other end of the driven shaft; a A central rotating shaft, one end of the central rotating shaft is provided with an axial flow fan blade connected to the connecting pipe, and the other end is provided with a tray and connected to the inner ring of the sealed bearing; a filter cage is fixed between the connecting pipe and the tray, and connected to the connecting pipe There is also a rotating filter screen in the filter cage at the junction; several spiral oil sweeping blades are evenly arranged along the central rotating shaft, and several sets of centrifugal oil sweeping blades are vertically arranged between the connecting pipe and the rotating disk. Several sets of centrifugal oil-sweeping blades between the pipe and the rotating disk are also covered with noise-absorbing filter screens on the outer diameter edges; the central rotating shaft at the connecting pipe is also provided with axial flow fan blades. The separator overcomes the shortcomings of the existing rotary centrifugal oil-gas separator, and can effectively reduce the decibel value of the aerodynamic noise while improving the oil-gas separation efficiency.

Description

technical field [0001] The invention belongs to the technical field of fuel engine environmental protection and energy saving, and relates to a technology for recovering engine oil leaking from a crankcase of a fuel engine, in particular to a low-noise rotary capture adsorption type oil-gas separator. Background technique [0002] Because there is a gap between the cylinder and the piston of the fuel engine, a small amount of high-pressure combustible mixture and burned gas in the cylinder will leak into the crankcase when the engine is running, resulting in blow-by gas, which contains a small amount of oil mist. Blow-by gas will cause the pressure of the crankcase to be too high and damage the seal of the crankcase. In order to prevent the pressure in the crankcase from being too high, the crankcase must be ventilated. In order to prevent the oil mist in the crankcase ventilation from directly entering the engine intake system or being directly discharged into the atmosphe...

AI Technical Summary

Problems solved by technology

[0003] In the existing rotary centrifugal oil-gas separator, when the centrifugal blades rotate at high speed, high-decibel aerodynamic noise will be generated, resulting in an increase in the decibel value of the overall noise of the engine
