Oil-gas separator provided with conical spiral channel

Abstract

The invention discloses an oil-gas separator provided with a conical spiral channel. The oil-gas separator comprises a conical spiral core (1), a conical outer shell (2), an upper cover (3) and an oil collection hopper (4). By adopting the device composed of the components, the upper cover is located on the conical spiral core, the oil collection hopper is located under the conical outer shell, the conical spiral core is sleeved with the conical outer shell, and the downward spiral channel defined by a conical barrel, conical spiral ribs and the conical outer shell is the conical spiral channel; a cavity defined by the oil collection hopper, the conical spiral core and the upper cover is an air chamber; an oil mist inlet communicates with the upper end of the conical spiral channel, the lower end of the conical spiral channel communicates with the oil collection hopper, and an exhaust port communicates with the air chamber. During working, according to the technical scheme that oil mist enters the conical spiral channel through the oil mist inlet and is separated into oil and gas under the action of centrifugal force, the purposes of structure simplifying, non-maintenance, non-failure, cost reduction and high oil-gas separation rate of the oil mist of the oil-gas separator are achieved.

Description

technical field [0001] The invention relates to an oil-gas separator, in particular to an oil-gas separator provided with a conical spiral channel for separating oil mist in a crankcase of a diesel engine into oil liquid and gas. Background technique [0002] The oil and gas separators in the prior art are called filter element type with filter element structure, cyclone type with conical hollow structure, and centrifugal type with rotating blade structure. Among them, the filter element type oil and gas separator operates The method is pass-through, and the filter element needs to be updated regularly during operation, which is cumbersome and costly to operate and maintain; the cyclone oil-gas separator, which operates in the pass-through type, separates tiny mist-like oil droplets with a diameter of about 1 micron suspended in the gas during operation The effect is poor; the centrifugal oil-gas separator, the operation mode is active, the structure is complex, the rotation...
