Abstract
The ammonia refrigeration system capable of recycling lubricating oil is formed from compressor, oil-ammonia separator, condenser, air separator, reservoir, low-pressure circulating cylinder, evaporator and various control elements, and is characterized by that the reservoir is matched with the oil-catching subcooler to make the lubricating oil separated out before it comes into low-pressure portion so as to make the lubricating oil do not come into the low-pressure portion and prevent it from affecting refrigeration.
Description
A kind of ammonia refrigeration system of recycling lubricating oil belongs to refrigeration technology field.
In the prior art, ammonia refrigeration system be by compressor, when compression (twin-stage have intercooler), oily ammonia separator, condenser, liquid reservoir, low pressure recycle bucket, evaporimeter, oil catcher, air separator, and various control elements etc. connect to form.During work, compressor needs oil lubrication, and lubricating oil can enter the circulatory system with ammonia, because ammonia is insoluble in lubricating oil, easily forms oily mould in conduct heat table and pipeline, hinders and conducts heat and liquid flow.In low-pressure sections such as circulation bucket and evaporimeters, because temperature is low, oil viscosity is big, accumulates over a long period, and forms thick oil film, is difficult to simple removing especially, and high-pressure section is owing to the temperature height, and oil viscosity is little, and good fluidity can not form too thick oil film.The method that adopts is that oily ammonia separator is set between compressor and condenser now, but in actual behaviour's work, best washing type oil eliminator also only separates 80-85%, still has parts of lubricating oil to enter the low-pressure section of system, works the mischief.
The purpose of this invention is to provide the recycling lubricating oil of a kind of energy and prevent that lubricating oil from entering the ammonia refrigeration system of low-pressure section, to overcome the deficiencies in the prior art.
The objective of the invention is to finish like this: it is connected to form by compressor, oily ammonia separator, condenser, liquid reservoir, oil-collecting subcooler, low pressure recycle bucket, evaporimeter, air separator and various control element, liquid reservoir is placed and the horizontal plane relative tilt, a lower end is installed oil-collecting subcooler feed pipe, give oil-collecting subcooler feed flow, a higher end is installed low pressure recycle bucket feed pipe, crosses through the oil-collecting subcooler to be connected with the low pressure recycle bucket after cold.
During the twin-stage compression, the oil-collecting subcooler is replaced by intercooler.
The said oil-collecting subcooler of the present invention is made of serpentine coil, shell, ball-cock assembly, by-passing valve and various by-pass valve control.
Accompanying drawing is a system of the present invention pie graph
Describe embodiments of the invention below in detail
It is connected to form by compressor 1, oily ammonia separator 2, condenser 3, liquid reservoir 4, oil-collecting subcooler 5, low pressure recycle bucket 6, evaporimeter 7, air separator 8 and various control element, liquid reservoir is placed and the horizontal plane relative tilt, its angle is the 3-5 degree, a lower end is installed oil-collecting subcooler feed pipe, give oil-collecting subcooler feed flow, a higher end is installed low pressure recycle bucket feed pipe, crosses through the oil-collecting subcooler to be connected with the low pressure recycle bucket after cold.
The said oil-collecting subcooler of the present invention is made of shell, the serpentine coil and ball-cock assembly, by-passing valve and the various by-pass valve control that are installed in the shell.
Because above structure, oil can fully precipitate in liquid reservoir, and can in time transfer in the oil-collecting subcooler, utilizes again in order to compressor; And will be very pure from the ammoniacal liquor of the high-end discharge of liquid reservoir, thereby having stopped oil enters low-pressure section, refrigeration system is not constituted harm.
Adopt the ammonia refrigeration system of twin-stage compression, the oil-collecting subcooler can be replaced by intercooler.
The present invention is on the basis of existing refrigeration system, adopt and tilt to place liquid reservoir, feed flow to low pressure recycle bucket and oil-collecting subcooler inserts from the diverse location of liquid reservoir respectively, thereby make the oil pole that enters into low-pressure section few, and do not constitute harm to refrigeration system, not only improve operating efficiency, reduced oily waste simultaneously.
