Oil-gas separator

Abstract

The invention relates to an oil-gas separator, which comprises an oil-gas pre-separator and an oil-gas separator used to separate oil and gas via expansion. Wherein, the gas outlet of oil-gas pre-separator is through to the gas inlet of oil-gas separator; the oil-gas pre-separator and the oil-gas separator have their independent oil flux; the oil and gas from the crank box via expanding has slow speed, while some oil is deposited on the inner wall of expansion frame to be collected via flux oil tube to the oil bottom frame; the non-separated oil and gas via gas outlet tube is fed to the main separator; since it processes pre-separation, the oil and air can be separated completely; the pre-separator can prolong the service life of whole system; the oil and gas via two separation are separated effectively, to improve the reliability of whole machine.

Description

technical field [0001] The invention relates to a device for separating oil and gas discharged from a crankcase. Background technique [0002] The mixed gas discharged from the crankcase of the internal combustion engine contains engine oil. During the recovery and combustion process, it will be adsorbed on various parts of the internal combustion engine, forming carbon deposits, reducing the working performance of the internal combustion engine, accelerating the wear and tear of the internal combustion engine and wasting oil, reducing the working efficiency of the engine and shortening life, while emitting more harmful gases to pollute the environment. Ordinary oil and gas separators mainly separate oil and gas through the filtering effect of the filter, but the filter or filter is also easy to block, and the pressure in the crankcase cannot be adjusted and balanced under the continuous negative pressure of the internal combustion engine. Someone also designs other oil-gas...

[0002] The mixed gas discharged from the crankcase of the internal combustion engine contains engine oil. During the recovery and combustion process, it will be adsorbed on various parts of the internal combustion engine, forming carbon deposits, reducing the working performance of the internal combustion engine, accelerating the wear and tear of the internal combustion engine and wasting oil, reducing the working efficiency of the engine and shortening life, while emitting more harmful gases to pollute the environment

Ordinary oil and gas separators mainly separate oil and gas through the filtering effect of the filter, but there are also filters or filters that are easy to clog, and the pressure in the crankcase cannot be adjusted and balanced under the continuous negative pressure of the internal combustion engine.

Some people have also designed other oil-gas separation devices such as labyrinth and negative pressure control, but there are technical problems such as inability to adjust and balance the pressure of the crankcase and the inability to fully and efficiently separate the mist oil.

[0003] At present, the oil-gas separator used on the internal combustion engine has a large change in the airflow velocity of the crankcase exhaust, and a large number of oil droplets are entrained in the oil-gas. It is difficult for the general oil-gas separator to meet the requirements of oil-gas separation, and the separation system will be blocked in a short time. , resulting in incomplete separation of oil and gas, reducing the service life of the separation system
