Abstract
The invention discloses a centrifugal high-efficiency oil separator, which comprises a centrifugal separation area and a filtering separation area, wherein a flow guide device is arranged at the top end of a cylindrical inner pipe of the centrifugal separation area, annular filtering separation areas are arranged around the flow guide device, and the flow guide device enables a rotational flow sprayed out of the cylindrical inner pipe to be vertically and radially injected to the annular filtering separation areas; the central axis of the cylindrical inner tube in the centrifugal separation area is staggered with the central axis of the centrifugal separation area by a distance d. The invention has the advantages that the cyclone centrifugal machine mechanism is combined with the filtering device, so that oil drops with larger particles and micro oil drops can be separated, the oil separation efficiency is high, and the airflow pressure is reduced.
Description
Technical field
The present invention relates to a kind of oil eliminator, particularly a kind ofly be used for refrigeration system is separated lubricating oil from cold-producing medium centrifugal high effective oil eliminator.
Background technology
In refrigeration system, compressor needs lubricating oil to run well usually.Can be mixed with lubricating oil in the compressor air-discharging; Usually between compressor and condenser, oil eliminator be installed, lubricating oil is separated from gaseous refrigerant, guarantee its normal operation so that lubricating oil can be got back to compressor; And prevent that lubricating oil from hindering the cold-producing medium heat exchange, improves system effectiveness.
Centrifugal oil eliminator is widespread usage; Centrifugal oil eliminator is used eddy flow centrifugal force and is separated oil droplet, and it can only isolate the bigger oil droplet of most of particle, and small mist of oil can't receive centrifugal forces affect; Continue to stay in the refrigeration system but follow refrigerant gas, reduced system effectiveness.And will increase along with refrigerant system capacity, the oil eliminator volume will constantly increase, otherwise its pressure falls and certainly will sharply increase, thus significantly reduce system effectiveness.In like manner, improve centrifugal oil eliminator separative efficiency, can run counter to desire by increasing air velocity.
Summary of the invention
Technical problem to be solved by this invention is that a kind of centrifugal high effective oil eliminator that improves separative efficiency, reduces the air-flow pressure will be provided.
In order to solve above technical problem; The invention provides a kind of centrifugal high effective oil eliminator; Comprise centrifugal separating area and isolated by filtration district; The pipe top is equipped with guiding device in centrifugal separating area cylindrical, is the annular filter Disengagement zone around the guiding device, guiding device make cylindrical in the eddy flow of pipe ejection radially vertically be sprayed onto the annular filter Disengagement zone.
Said guiding device is to make eddy flow become straight device, makes eddy flow become straight, and air-flow can be distributed on the annular filter Disengagement zone in downstream relatively equably.Guiding device can be annular porous plate, or annular honey-comb grate.
Pipe axis and the centrifugal separating area axis distance, d that staggers in cylindrical in the said centrifugal separating area, under the situation that does not increase the separator diameter, the increase separator inlet gas flowing space reduces flow resistance.
Be provided with shoe cream room below the said centrifugal separating area, the circular dividing plate of one edge fluting is arranged between shoe cream room and the centrifugal separating area.The oil that centrifugal separating area is separated is because the factor of gravity flows in the shoe cream room through the fluting of circular dividing plate downwards along the oil eliminator wall, and the oil in the shoe cream room returns compressor through oil return pipe.
Operation principle of the present invention: refrigerant gas gets into from the inlet tube of centrifugal separating area; Getting into centrifugal separating area manages in cylindrical; Form eddy flow, and then produce the effect that centrifugal force plays the separation oil droplet, the effect of centrifugal separating area is the bigger oil droplet of separating particles.Eddy flow makes air-flow be distributed to the annular filter Disengagement zone equably through guiding device, and the effect of annular filter Disengagement zone is when refrigerant gas passes through, to filter remaining small oil droplet, plays the effect of thorough separation mist of oil, thereby has improved oily separation efficient.The oil that filters out is accumulated in the oil groove below the filtering area, and returns compressor through valve.The refrigerant gas of oil-containing is not then discharged from the outlet of oil eliminator.
Superior effect of the present invention is:
1) the present invention adopts eddy flow centrifugal force mechanism and filter to combine, and has both isolated the bigger oil droplet of particle, can isolate small oil droplet again, so oil separates the efficient height;
2) guiding device can be utilized filter fully, separates efficient thereby further improve oil;
3) pipe axis and the centrifugal separating area axis segment distance that staggers in cylindrical in the centrifugal separating area under the prerequisite that does not increase the separator diameter, helps to reduce air-flow and presses, thus raising refrigeration system efficient.

The specific embodiment
See also shown in the accompanying drawing, the present invention is done further description.
As depicted in figs. 1 and 2; The invention provides a kind of centrifugal high effective oil eliminator; Comprise centrifugal separating area and isolated by filtration district; Pipe 2 tops are equipped with guiding device 3 in centrifugal separating area cylindrical, are annular filters 4 around the guiding device 3, guiding device 3 make cylindrical in the eddy flow of pipe 2 ejections radially vertically be sprayed onto annular filter 4.
Said guiding device 3 is to make eddy flow become straight device, makes eddy flow become straight, and air-flow can be distributed on the annular filter 4 in downstream relatively equably.Guiding device 3 can be annular porous plate, or annular honey-comb grate.
Pipe 2 axis and the centrifugal separating area axis distance, d that staggers in cylindrical in the said centrifugal separating area, under the situation that does not increase the separator diameter, the increase separator inlet gas flowing space reduces flow resistance, improves the efficient of whole refrigeration system.
Be provided with shoe cream room 6 below the said centrifugal separating area, the circular dividing plate 5 of one edge fluting is arranged between shoe cream room 6 and the centrifugal separating area.The oil that centrifugal separating area is separated is because the factor of gravity flows in the shoe cream room 6 through the fluting of circular dividing plate 5 downwards along the oil eliminator wall, and the oil in the shoe cream room 6 returns compressor through oil return pipe 7.
Operation principle of the present invention: refrigerant gas gets into from the inlet tube 1 of centrifugal separating area; Get into centrifugal separating area and in cylindrical, manage 2; Form eddy flow, and then produce the effect that centrifugal force plays the separation oil droplet, the effect of centrifugal separating area is the bigger oil droplet of separating particles.Eddy flow makes air-flow be distributed to annular filter 4 equably through guiding device 3, and the effect of annular filter 4 is when refrigerant gas passes through, to filter remaining small oil droplet, plays the effect of thorough separation mist of oil, thereby has improved oily separation efficient.The oil that filters out is accumulated in the oil groove below the filter 4, and returns compressor through valve 8.The refrigerant gas of oil-containing is not then discharged from the outlet 9 of oil eliminator.
