Description
Technical field
The present invention relates to the compressor cooling circulatory system, refer to particularly the afterheat recovery type oil eliminator in a kind of compressor cooling circulatory system.
Background technology
In the compressor cooling circulatory system, become high temperature and high pressure gas after the compressed machine compression of low-temp low-pressure gas, high temperature and high pressure gas becomes normal temperature high voltage liquid after condenser heat exchange condensation, normal temperature high voltage liquid becomes the low-temp low-pressure liquid-vapor mixture after the throttling arrangement throttling, the low-temp low-pressure liquid-vapor mixture becomes again low-temp low-pressure gas after evaporimeter heat exchange evaporation, then get back in compressor, so constantly circulation forms cooling cycle system.
In actual cooling cycle system, need to add lubricating oil be lubricated, seal and lower the temperature compressor.The refrigerant gas that is actually HTHP of therefore, discharging through compressor compresses and the gas mixture of lubricating oil.The existence of lubricating oil can reduce the heat transfer effect of condenser and evaporimeter, thereby affect refrigeration, therefore need between exhaust outlet of compressor and condenser, arrange oil eliminator to gas mixture carry out oil, gas separates, and avoids lubricating oil to enter condenser and evaporimeter.
Gas mixture is separated into refrigerant gas and lubricating oil liquid through oil eliminator.Then refrigerant gas enters the refrigerant liquid that condenser condenses is normal temperature high voltage, and lubricating oil liquid enters the cooling rear temperature of oil cooler to be reduced.In said process, the temperature of gas mixture is usually 85 ℃ of left and right, can consider this partial heat energy for the preparation of hot water for the place needed, such as: food processing, animals and poultry slaughtering, hotel, hotel etc., realize the recycling of waste heat, reach energy-saving and cost-reducing purpose.
At present, mainly contain two kinds of processing modes for this partial heat energy: the first directly is discharged in the Nature by condenser and oil cooler; It two is a heat exchanger to be set on condenser or heat exchanger is set between oil eliminator and condenser to produce the place of hot water for needs.The equal Shortcomings part of above two kinds of processing modes: to the first processing mode, this partial heat energy is released in the Nature fully, is not used effectively, and not only will consume extra energy this partial heat energy is taken away, and also can cause environmental disruption.To the second processing mode, although the heat to refrigerant gas in gas mixture is recycled, but wherein the heat of lubricating oil liquid is released in the Nature, not only to consume extra energy this partial heat energy is taken away, also can cause environmental disruption.Simultaneously, heat exchanger be arranged on condenser or oil eliminator and condenser between, cause the equipment connected structure to disperse, medium connects piping and is tending towards complicated, the heat energy increasing of running off in course of conveying, cause utilization rate of waste heat very low.
The separate unit LG20III screw type refrigerating compressor group of take is example, when evaporating temperature-25 ℃, and during 38 ℃ of condensation temperatures, the about 190KW of the heat that can recycle in its gas mixture.If the employing first kind of way, this heat is fully discharged in atmosphere, in system, is additionally each, condenser and oil cooler coupling 7.5KW water pump, and the electric energy additionally consumed every year is 18.5 ten thousand KW approximately; If the employing second way, although can reclaim about 34KW heat, need approximately 9.5 ten thousand KW of the extra electric energy consumed every year simultaneously.
As can be seen here, above two kinds of processing modes, the heat of its gas mixture is not recovered utilization fully, also can consume additional electrical energy, causes environmental disruption, all the Shortcomings part.Therefore, how to make the heat of gas mixture fully be recovered utilizing is a problem needing solution in refrigeration industry badly.
