Description
Technical field
The present invention relates to a kind of segregation apparatus, especially relate to a kind of oil eliminator.
Background technology
The efficiency of oil eliminator always is the key factor of the overall performance affecting a lot of equipment, oil eliminator inefficiency, can cause entering the oil of heat exchanger too much, be internally formed oil film at heat exchanger, add heat exchange thermal resistance, affect heat transfer effect；The oil mass also resulting in return compressor is very few, increases compressor inter deterioration, affects the life and reliability of compressor, so improving oil eliminator efficiency have urgent requirement.It addition, the needs produced along with life, a lot of equipment increasingly trend towards miniaturization, it requires that the various accessories including oil eliminator also will be toward miniaturization.And the internal accessory that there is drainage screen, dividing plate of existing oil eliminator, add oil point inlet and outlet pressure loss, and majority volume is bigger. more；Even if there being small-sized oil eliminator, lacking the parts such as filter screen, dividing plate due to inside again, separation efficiency is the highest.Therefore, it is necessary to study new and effective small-sized oil eliminator.
In order to make oil eliminator miniaturization, prior art have employed oil eliminator is made tubular structure, as it is shown in figure 1,50 is housing, being its two ends cylindrical shape of being condensed to taper, housing 50 has the upper conical part of the lower conical portion on the downside of cylindrical portions, cylindrical portions and upside.51 is columnar effuser, runs through the apex portion of the upper conical part of housing 50, and it is internal to insert housing 50, and be fixed as coaxial by this effuser 51 with the central shaft of housing 50.52 is discharge pipe, is fixed under shed 50a, and this under shed 50a is formed at the apex portion of the lower tapered segment of housing 50.53 is to flow into pipe, is the cylindrical duct shape of a diameter of D, is tangentially connected with cylindrical portions (not shortening the part of taper into) internal face in housing 50.It addition, the end 51a of the part that the insertion of effuser 51 is within housing 50, it is positioned at the distance that central lower is L1 of the housing inner end flowing into pipe 53, and the under shed 50a being positioned at housing 50 is arranged above the distance of L2.The two-phase flow that the refrigerant gas discharged by compressor and refrigerator oil form flows in housing 50 from flowing into pipe 53.The gas-liquid two-phase flow flowed in housing 50 spirally rotates decline in housing 50.Created the so-called cyclonic effect adhered to owing to colliding with the inner peripheral surface of housing 50 by the mist of oil (small of refrigerator oil is drawn) of centrifugal action owing to this rotates, the mist of oil in refrigerant gas that swims separates from refrigerant gas successively.Flowed out from effuser 51 by the refrigerant gas having separated mist of oil, and the refrigerator oil being attached to housing 50 internal face declines along housing 50 internal face due to the effect of gravity, discharge from discharge pipe 52, and via capillary flow to returning oil return line, return compressor by hydraulic accumulator.But the oil eliminator of this structure of the prior art lacks the parts such as filter screen, dividing plate due to inside, and separation efficiency is the highest.
