Background
Most of compressors in a refrigeration system adopt oil injection cooling or lubrication. The lubricating oil is used for lubricating between each friction pair and reducing the exhaust temperature of the compressor. However, the lubricating oil is a medium with poor heat exchange performance, and when the lubricating oil in the compressor enters heat exchange equipment such as a condenser, an evaporator and the like, an oil film is formed on a heat transfer surface, so that the heat transfer coefficients of the lubricating oil and the heat exchange equipment are reduced, the effective heat transfer area is reduced, the condensing temperature is increased, the evaporating temperature is reduced, and the refrigerating capacity is reduced. Therefore, after the compressor exhausts, an oil treatment device is added before the compressor enters a condenser, most of lubricating oil in the compressor exhaust is separated out and is sent back to the compressor after being cooled. And current oily processing apparatus adopts multilayer filter screen filterability lubricating oil more, utilizes the mesh on the filter screen to circulate gas to the mesh size of filter screen reduces step by step, consequently, will lead to gaseous circulation speed slow, and separation efficiency is not high, and does not set up the heat preservation measure, leads to the refrigerant in the gas-oil mixture gas to condense on the filter screen and mix with the lubricating oil through giving out heat, thereby is difficult to separate.
SUMMERY OF THE UTILITY MODEL
In view of this, the utility model aims at providing a have that gas-oil separation is effectual, separation efficiency is high and keep warm effectual high-efficient heat transfer central air conditioning oil branch is taken over.
In order to solve the technical problem, the technical scheme of the utility model is that: the utility model provides a high-efficient heat transfer central air conditioning oil divides takeover, includes the body, sets up body top and with the outlet duct of body intercommunication sets up the intake pipe of body side sets up body bottom and with the back flow of body intercommunication, and set up filling chamber in the body sets up filter screen in the body and above being located filling chamber.
Preferably, a plurality of polyhedral hollow spheres are arranged in the filling cavity.
Preferably, one end of the return pipe close to the pipe body is provided with a flow valve.
Preferably, the upper end and the lower end of the tube body are both arranged in a closing-up mode.
Preferably, the outer wall of the pipe body is provided with a heat insulation layer.
Preferably, the end of the intake pipe is chamfered.
The utility model discloses technical effect mainly embodies: the heat-insulating layer is matched with the pipe body, so that the temperature in the pipe body is favorably kept, the refrigerant gas is prevented from being released and solidified and cannot be separated from lubricating oil, the gas-oil mixed gas in the gas inlet pipe is fully contacted with the multi-surface hollow ball through the matching of the gas inlet pipe and the multi-surface hollow ball, the lubricating oil on the gas-oil mixture is condensed on the multi-surface hollow ball, and the refrigerant gas flows out from gaps, so that the gas-oil separation is realized, the gas fluidity of the multi-surface hollow ball is good, the separation efficiency is high, and the separation effect is improved through the synergistic effect of the; therefore, the gas-oil separator has the advantages of good gas-oil separation effect, high separation efficiency and good heat preservation effect.
