New type oil gas separator

Abstract

The invention discloses a new type oil gas separator, comprising a separator shell, wherein an air outlet pipe is arranged at the upper part of the separator shell; an air inlet pipe is arranged at the lower part of the separator shell; a filter element assembly is arranged in the separator shell; the upper end of the air inlet pipe is connected with the bottom of the filter element assembly; the filter element assembly consists of a shell, a baseplate, a crude separation baffle and a head cover, the baseplate is located at the bottom of the shell, the crude separation baffle is arranged above the baseplate, the head cover seals the top of the shell, the edges of the head cover extend downwards and forms an air block body at the periphery of the upper part of the shell, a first through hole is formed in the baseplate, a second through hole is formed above the side walls of the shell, and is rightly opposite to the air block body, and an oil outlet is formed in the bottom of the separator shell. The separator disclosed by the invention has the advantages that the layout is reasonable, the volume of the whole oil gas separator is relatively small, the structural arrangement of an engine is optimized, tests of the oil gas separator are facilitated, and the maintaining cost in a later period is effectively reduced.

Description

technical field [0001] The present invention relates to an engine accessory, more specifically, it relates to a novel oil-gas separator. Background technique [0002] Oil and gas separation technology is a technology that separates oil and gas from the exhaust gas in the engine crankcase and discharges the excess exhaust gas into the atmosphere. Oil-gas separation technology is a growing technology in the engine field. With the call of the national energy-saving and emission-reduction policy, the concept of environmental protection must be integrated into product design. The existing oil-gas separation is mainly achieved in two ways. One is to rely on the inertia of the airflow to make the airflow produce circular rotation, impact and return, centrifugal rotation or zigzag movement, thereby changing the speed and direction of the oily airflow and separating out particles with smaller particle sizes. Large oil droplets; the other is to absorb and condense fine oil mist throu...

AI Technical Summary

Problems solved by technology

[0004] 1. It is large in size and takes up a lot of space in the engine. It needs to be used in combination with the cylinder head cover. It is relatively troublesome to design and manufacture, and it is difficult to modify the structure, which increases the difficulty of engine layout;

[0005] 2. The structure is complex, which is not conducive to the later stage of the oil-gas separator test and the statistics of the test data;

[0006] 3. The production process is complicated, which increases the production cost and increases the post-maintenance cost of the oil-gas separator;

[0007] 4. The oil and gas separation effect is poor
