Description
Technical field
The invention belongs to CO2Air source heat pump technical field, and in particular to one kind is used for CO2The oil separation of air source heat pump
Device.
Background technology
In heat pump, compressor wants trouble free service, it is necessary to effectively prevents liquor and lubricates the hair of oil starvation phenomenon
Raw, lubricating oil plays lubrication, cooling and sealing function in compressor, and serious damage will be caused to compressor by lacking lubricating oil
It is bad, lubricating oil it is excessive be deposited on condenser and evaporator, can also cause the heat exchange efficiency of heat exchanger to decline, influence whole equipment
Efficiency, in relatively large heat pump assembly, oil eliminator is set.
Oil eliminator has the ability for coming out lubricating oil separation from refrigerant air-liquid mixture, makes into condenser
Lubricating oil is reduced, so as to promote the more efficient operation of heat pump.According to point oil for reducing air velocity and change airflow direction
Principle, the elaioleucite in high steam is set to be separated under gravity.General air velocity is in below 1m/s, so that it may by steam
In elaioleucite of the contained diameter in more than 0.2mm separate.Usually used oil eliminator has washing type, centrifugal, material filling type
With four kinds of filtering type.
At present in the heat pump of normal air source, ammonia steam (or freon steam) after compression is to be in high pressure-temperature
Superheat state, flow velocity when being discharged due to it is fast, temperature is high, the part lubricating oil on cylinder wall by high temperature effect unavoidably into oil
Steam and oil droplet particulate are together discharged with refrigerant vapour.And exhaust temperature is higher, flow velocity is faster, then the lubricating oil discharged is got over
It is more.Maximum pressure is generally no greater than 4MPa inside the heat pump refrigerant pipe of normal air source, and temperature is not higher than 100 degree, and CO2Air-source
Pressure in heat pump refrigerant pipe is in 8-12MPa, and for temperature between 110-150 degree, plain edition oil eliminator can not be effectively by profit
Lubricating oil is deposited in oil eliminator, lubricating oil can be made to follow CO2High-temperature steam is taken away or evaporated together, does not reach the work(of oil storage
Can, cause the missing of internal system lubricating oil and damage compressor.
The content of the invention
The invention aims to solve technical problem present in prior art, there is provided one kind can be effectively by cold media
Matter is separated with lubricating oil and what good separating effect, fractional dose were big is used for CO2The oil eliminator of air source heat pump.
In order to achieve the above object, the present invention uses following technical scheme：One kind is used for CO2The oil separation of air source heat pump
Device, including top have the ampuliform housing of an opening, and the open top of the housing, which is provided with the middle part of seal closure and seal closure, to be set
There is gas vent, the open top inwall of the housing is provided with oil gas filter core, and the bottom of the oil gas filter core is provided with porous plate
Flow-disturbing component, the housing upper side wall are provided with gas mixture import, and center position is provided with out vertically in the housing
Tracheae, is provided with spiral stream guidance board component between the escape pipe and inner walls, the housing inner bottom part is provided with oil storage cabin and storage
Bunker is located at the lower section of spiral stream guidance board component, and the oil storage cabin side wall is provided with oil export.
Further, expansion spring is provided between the gas vent and seal closure.
Further, ball-cock assembly is provided with the oil export.
Further, the escape pipe internal upper part is provided with filtration core.
Further, the porous plate flow-disturbing component is double-deck spiral shell shape porous plate flow-disturbing component.
Further, the oil gas filter core is the high-accuracy oil gas filter core of annular.
The present invention has the advantages that compared with the prior art：The present invention is provided with oil storage part in ampuliform housing, divided
From part and filter element, oil storage part includes oil storage cabin and oil export, and separating component includes spiral stream guidance board component and outlet
Pipe, filter element include oil gas filter core, and separating component of the invention is by spiral stream guidance board component gas mixture from upper
And lower flowing, first time separation is carried out to gas mixture using the coolant media principle different with the density of lubricating oil, not only
Oil-gas Separation amount is big, and serves the purpose for reducing oil temperature, and the lubricating oil after separation is drained to oil storage part from inner walls
In, after the coolant media steam after separation moves to porous plate flow-disturbing component from escape pipe from below to up, porous plate flow-disturbing component
The lubricating oil choked flow that will be carried again in coolant media, the purpose of secondary oil gas separation is realized, passes through porous plate flow-disturbing component
Coolant media steam carries out third time Oil-gas Separation in the presence of oil gas filter core to coolant media.The present invention is separated using three-level
Technology, effectively coolant media and lubricating oil being separated, separation rate reaches more than 80%, meanwhile, coolant media can be to separation
Lubricating oil afterwards is cooled down, and both ensure that compressor normal work, has been reached the purpose of cutting oil oil temperature again, has been avoided
Lubricating oil follow high temperature and high pressure gas carry out systemic circulation and caused by loss, decrease lubricating oil return compressor distance,
Solves CO2The difficult technical bottleneck of air source heat pump oil return, extends the service life of compressor, is CO2Air source heat pump is extensive
Using laying a good foundation.
