Description
Technical Field
The invention relates to the technical field of oil-gas separators of engines, in particular to a side-entering ejection type oil-gas separator.
Background
As early as the nineteenth century, oil-gas separators were used by people, but the use of oil-gas separators in automobile engines was still in the sixties of the last century, and domestic research into oil-gas separation technology was still later. During this period, many workers and researchers at home and abroad have developed research work on separators, from the initial experimental fumbling stage to the research period of combining theory and experiment today. At present, the oil-gas separator has various structural forms, but the design standard and specification are not uniform. In the background of the current higher and higher requirements on separation efficiency, most researchers at home and abroad tend to be two-stage type or multi-stage type separators.
The working principle of the active centrifugal oil-gas separator is that the rotation vortex is formed in the separator by the external input energy, and the particles in the mixed air flow are separated out under the action of centrifugal force. The common use is an active centrifugal separator of conical form, wherein a plurality of conical discs are arranged on the rotating shaft of the active centrifugal separator, small holes are arranged on the discs close to the rotating shaft, namely, the circulation channel of the mixed gas, and a group of arc-shaped blades are arranged on each disc. When the rotating shaft moves, the mixed gas is thrown out along the annular space between the conical discs under the action of centrifugal force, so as to achieve the purpose of oil-gas separation.
The top inlet side outlet type oil-gas separator has one air inlet channel in the top, one air outlet channel in the side, one separating cavity inside the casing, one laminated conic disc inside the separating cavity, and mixed gas entering from the air inlet channel via the axial direction of the conic discs, and one centrifugal separation of the mixed gas into the interval between the conic discs, with the mixed gas being separated into gas and liquid in the interval between the conic discs, the liquid being thrown onto the inner wall of the casing and flowing downwards, and the gas being exhausted from the air outlet channel below the discs via the channel into the side. Because the separation cavity is not used for carrying out standard division on the air inlet flow channel and the air outlet flow channel, mixed gas which is not subjected to gas-liquid separation is mixed in the separated waste gas and is discharged from the air outlet channel, the separation efficiency is low, and the waste of resources and the pollution to the environment are easily caused.
Therefore, there is a need for an improvement in the structure of the existing oil separator.
