Description
Technical field
The utility model relates to the central air conditioner main machine system regions providing hot and cold water, is specifically related to a kind of vertical oil-gas separator with dual centrifugation.
Background technology
The gs-oil separator used in screw cold water (heat pump) unit in current refrigerating and air conditioning industry mainly contains Horizontal oil-gas separator and this two class of vertical oil-gas separator from a structural point.The suction-operated that Horizontal oil-gas separator mainly utilizes gas mixture to pass through to be arranged at the woven wire of its inside makes oil (refrigerator oil) gentle (refrigerant gas) be separated.The oil (refrigerator oil) gentle (refrigerant gas) that the centrifugal acceleration that vertical oil-gas separator mainly utilizes gas mixture to rotate generation within it makes is separated.
For vertical oil-gas separator, gas mixture during duty in it rotate the centrifugal acceleration produced be proportional to its linear velocity square, be inversely proportional to the radius of rotation.When screw cold water (heat pump) unit configuring vertical oil-gas separator is in sub-load, the linear velocity of vertical oil-gas separator interior gas mixture reduces along with the reduction of unit load, when unit is in minimum load, the linear velocity of gas mixture is minimum of a value, when radius of turn is constant, rotating the centrifugal acceleration produced is also minimum of a value, means that now vertical oil-gas separator separating power is the poorest, and the risk that unit loses oil is maximum.
Utility model content
For above-mentioned technical problem, the utility model provides a kind of vertical oil-gas separator with dual centrifugation, can promote cold water (heat pump) unit separative efficiency of (1% ~ 100%) under all loads.
The utility model provides a kind of vertical oil-gas separator with dual centrifugation, and comprise cylindrical shell, be provided with escape pipe in cylindrical shell, cylindrical shell upper side is provided with air inlet pipe, it is characterized in that being provided with screen pack in bottom escape pipe.After refrigerant gas enters escape pipe, immediately through screen pack, through screen pack in gas, in gas, remaining oil droplet is attached on screen pack again separated, and remaining gas carries out heat exchange by entering condenser along escape pipe after screen pack.
Described screen pack is made up of wire.The thickness of screen pack is 5mm ~ 150mm.
The utility model structure is simple, utilize cylindrical shell to rotate and realize first time Oil-gas Separation, utilize suction-operated wiry in screen pack simultaneously, refrigerator oil particle in refrigerant gas, through screen pack, makes on its wire be attracted in screen pack, and increases gradually along with the olesome on the increase wire of time, finally fall under gravity to separator bottom, refrigerant gas, after filter screen, along escape pipe internal circulation until discharge, realizes oil gas secondary separation.The utility model can promote cold water (heat pump) unit separative efficiency of (1% ~ 100%) under all loads.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation
Wherein, 1-cylindrical shell, 2-air inlet pipe, 3-escape pipe, 4-screen pack.
Detailed description of the invention
Below in conjunction with Figure of description and specific embodiment, the utility model is described in further detail:
As shown in the figure, the utility model comprises cylindrical shell 1, is provided with escape pipe 3 in cylindrical shell 1.The top of gas outlet is fixedly connected with the top of cylindrical shell 1, and the bottom of gas outlet is arranged at the inside of cylindrical shell 1.Cylindrical shell 1 upper side is provided with air inlet pipe 2, and one end of air inlet pipe 2 is arranged with in cylindrical shell 1, and the other end exposes to outside cylindrical shell 1.Screen pack 4 is provided with in bottom escape pipe 3.Screen pack 4 is coated on the port, bottom of escape pipe 3.Screen pack 4 is made up of wire, and described wire becomes lattice-shaped to distribute.The thickness of screen pack 4 is 5mm ~ 150mm.
Screw cold water (heat pump) unit, is formed primarily of helical-lobe compressor, evaporimeter, condenser, gs-oil separator, electric expansion valve.Time in working order, bearing in helical-lobe compressor, rotor and star-wheel need refrigerator oil to lubricate, refrigerator oil enters compressor from vertical oil-gas separator bottom and arrives the position needing lubrication under the effect of pressure reduction, the mixture of refrigerant gases completed in the rear refrigerator oil of lubrication and compressor enters the air inlet pipe 2 of vertical oil-gas separator from exhaust outlet of compressor, as shown in the figure, cold-producing medium and refrigerator oil oil droplet mist are after air inlet pipe 2 enters separator, enter the first separation phase of separator: be specially gas mixture and rotate along cylindrical shell 1 circumferencial direction, the effect of centrifugal acceleration is subject in the process rotated, the refrigerator oil particle making density larger is subject to the larger centrifugal force of the refrigerant gas less relative to density, refrigerator oil particle " is got rid of " gradually goes out circular motion track, arrive cylindrical shell 1 wall along under wall flow.Remaining refrigerant gas enters separator escape pipe 3, enter the second separation phase of separator: be specially refrigerator oil particle in refrigerant gas when screen pack 4, be attracted on the wire in screen pack 4, and increase gradually along with the olesome on the increase wire of time, finally fall under gravity to separator bottom, refrigerant gas after filter screen 4, along escape pipe 3 internal circulation until discharge.For the first separation phase, its separating power be proportional to the linear velocity of gas mixture square, that is the load of unit is larger, and the linear velocity of gas mixture is larger, and its separating power is higher; For second stage, because separating power relies on suction-operated wiry in screen pack 4, therefore the speed of gas mixture is less, and the separating power of screen pack 4 is higher.The utility model can promote cold water (heat pump) unit separative efficiency of (1% ~ 100%) under all loads.
Obviously, those skilled in the art can carry out various change and modification to the utility model and not depart from spirit and scope of the present utility model.Like this, if these amendments of the present utility model and modification belong within the scope of the utility model claim and equivalent technologies thereof, then the utility model is also intended to comprise these change and modification.The content be not described in detail in this description belongs to the known prior art of professional and technical personnel in the field.
