Abstract
The invention discloses an oil separator, belonging to the separating device; the technical problem solved by the invention is to provide an oil separator, which has the characteristics of removing parts including a filter screen, a baffle plate and the like, reducing the inlet and outlet pressure loss, and fully reducing the volume. The technical scheme of the oil separator is that the oil separator comprises a cylinder body 1, as well as an intake tube 2, an exhaust tube 3 and an oil return tube 4 which are connected with the cylinder body 1; the cylinder body 1 comprises a straight tube part with a certain length and a tapered necking part reduced to both ends respectively; the exhaust tube 3 and the oil return tube 4 are respectively connected with an upper tapered necking port and a lower tapered necking port of the cylinder body 1; and the inner wall of the cylinder body is provided with a cylinder body liquid-collecting network 5. According to the oil separator, the inlet and outlet pressure loss of oil is reduced, and the volume of an oil-gas separator is reduced simultaneously, so that miniaturization design of an air conditioning system is facilitated, the oil amount of a heat exchanger is reduced, and the heat exchange effect is improved; the oil return of a compressor is timely and adequate, therefore, the reliable and stable operation of the compressor is ensured.
Description
Technical field
[0001] the present invention relates to a kind of separator, especially relate to a kind of oil eliminator.
Background technology
[0002] efficient of oil eliminator always is the key factor of the overall performance of a lot of equipment of impact, and the oil eliminator inefficiency can cause entering the too much oily of heat exchanger, at the inner oil film that forms of heat exchanger, has increased the heat exchange thermal resistance, affects heat transfer effect; The oil mass that also can cause returning compressor is very few, increases the compressor inter deterioration, affect the life and reliability of compressor, so raising oil eliminator efficient has urgent requirement.In addition, along with the needs that life is produced, a lot of equipment more and more trend towards the miniaturization development, so require to comprise that the various accessories of oil eliminator also will be toward the miniaturization development.And there is the accessory of screen pack, dividing plate in existing oil eliminator inside more, increased the loss of oil content inlet and outlet pressure, and most volume is larger; Even small-sized oil eliminator is arranged, because inside lacks the parts such as filter screen, dividing plate, separative efficiency is not high again.Therefore, be necessary to study new and effective small-sized oil eliminator.
In order to make the oil eliminator miniaturization, available technology adopting oil eliminator is made tubular structure, as shown in Figure 1, the 50th, housing, be the cylindrical shape that its two ends are condensed to taper, housing 50 has the inferior pyramidal part of cylindrical portions may, cylindrical portions may downside and the upper conical part of upside.The 51st, columnar effuser runs through the apex portion of the upper conical part of housing 50, and inserts housing 50 inside, and is fixed as the central shaft of this effuser 51 and housing 50 coaxial.The 52nd, discharge pipe is fixed under shed 50a, and this under shed 50a is formed on the apex portion of the lower tapered segment of housing 50.The 53rd, inflow pipe is that diameter is the cylindrical duct shape of D, tangentially is connected with cylindrical portions may (not shortening the part of taper into) internal face in housing 50.In addition, the end 51a of the part of insertion housing 50 inside of effuser 51, the central lower that is positioned at the housing inner end of inflow pipe 53 is the distance of L1, and the under shed 50a top that is positioned at housing 50 is the distance of L2.The two-phase flow that the refrigerant gas of being discharged by compressor and refrigerator oil form is in inflow pipe 53 inflow housings 50.The gas-liquid two-phase flow that flows in the housing 50 rotates decline in the shape of a spiral in housing 50.The mist of oil (small of refrigerator oil is drawn) that is subject to centrifugal action owing to this rotation has produced owing to the inner peripheral surface with housing 50 collides the so-called cyclone effect of adhering to, and the mist of oil that swims in refrigerant gas separates from refrigerant gas successively.The refrigerant gas of separated mist of oil flows out from effuser 51, and the refrigerator oil that is attached to housing 50 internal faces descends along housing 50 internal faces owing to action of gravitation, 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 is because inside lacks the parts such as filter screen, dividing plate, and separative efficiency is not high.
Summary of the invention
The technical problem that the present invention solves is: a kind of parts such as screen pack, dividing plate that removed are provided, have reduced the inlet and outlet pressure loss, fully dwindled the oil eliminator of volume.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: oil eliminator of the present invention comprises cylindrical shell 1 and the air inlet pipe 2 that links to each other with cylindrical shell 1, blast pipe 3, oil return pipe 4, the taper reducing part that described cylindrical shell 1 comprises the straight-tube portion of certain-length and dwindles to two ends respectively; Described blast pipe 3 links to each other with the upper inferior pyramidal reducing of cylindrical shell 1 respectively with oil return pipe 4; Cylinder inboard wall arranges cylindrical shell liquid collecting net 5.
Optimally, blast pipe 3 outer walls arrange blast pipe liquid collecting net 6.
