Centrifugal labyrinth type oil-gas separator with jet smashing function

Abstract

The invention discloses a centrifugal labyrinth type oil-gas separator with a jet smashing function. Compressed air sprayed out of a nozzle accelerates mixed oil gas and enables the mixed oil gas intoa turbulence state, and oil particles collide and rub with one another to be smashed. The smashed oil particles ascend along the gas through an annular track, due to the centrifugation of the annulartrack, the rough oil particles move along the outer side of the track, the fine oil particles move along the inner side of the track, and the fine oil particles enter a centrifugal labyrinth to be separated again. The rough oil particles continue to keep away from an inner inlet along the outer side of the annular track to be sent back into a smashing chamber, and the rough oil particles and newly-input mixed oil gas are smashed again. The fine oil particles flow along the gas in the centrifugal labyrinth and are condensed when encountering a baffle to be collected. The finally separated gasis exhausted through an outlet. The oil-gas separator jets the high-pressure gas to smash the mixed oil gas, oil-gas separation is carried out through the centrifugal labyrinth, the oil particles areprone to be condensed into drops under the action of the centrifugation and the baffle, the oil-gas separation efficiency is high, and the separation quality is guaranteed.

Description

technical field [0001] The invention relates to a centrifugal labyrinth oil-gas separator with jet crushing function, and aims to provide a high-efficiency oil-gas separator. Background technique [0002] In order to achieve the purpose of engine exhaust environmental protection and energy saving, the engine is equipped with a crankshaft forced ventilation device. Therefore, it is required that the gas recovered in the forced ventilation system of the crankcase should not contain oil droplets as much as possible when it is passed into the engine, otherwise it will affect the combustion of fuel in the engine cylinder, increase the degree of carbon deposition in the cylinder, and the emission of the engine will pollute the environment, so oil and gas are required Separation meets certain requirements. There are mainly three kinds of existing oil and gas separation methods: filter screen type oil and gas separator, labyrinth type oil and gas separator and cyclone type oil and ...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the shortcomings of insufficient oil-gas separation in the prior art, the present invention provides a jet crushing and centrifugal labyrinth oil-gas separator, which sprays compressed gas into the oil-gas mixture, and collides with the oil particles through the compressed gas. , friction, etc. to achieve crushing, through the centrifugal labyrinth chamber, due to the action of centrifugal force and baffle, the probability of oil particles colliding with the wall surface is increased, the oil particles are accelerated to condense and converge, and are recovered from the oil return tank
