Description

The invention relates to refrigeration technology, namely to compression chillers using ammonia, freons, carbonic acid, air, etc. as a refrigerant, and can be used in various industries where artificial cold is used.

An oil separator is known, which contains a cylinder in which a suction pipe with a segner wheel and grates for cleaning the outgoing vapors are located.

The disadvantage of this oil separator is the low efficiency of oil separation due to the large oil carryover by refrigerant vapor.

Also known is an oil separator containing a vertical cylindrical body with inlets and outlets for refrigerant vapor and perforated conical bumpers located in the upper part of the body.

The disadvantage of this oil separator is a reduction in the efficiency of oil separation in the process of work up to 60% due to the accumulation of oil, and, consequently, the draining of oil carryover into the system and its oiling. This leads to a higher consumption of electric power to produce a unit of cold. In addition, the disadvantage is the complexity of automating the process of oil release, since the bubbling causes constant mixing of the oil with the liquid refrigerant, the produced oil needs to be regenerated — cleaned of mechanical impurities before secondary use.

The aim of the invention is to intensify the oil separation process and ensure the regeneration of the oil, as well as the automation of the oil discharge process.

This goal is achieved by the fact that in the oil separator, which contains a vertical cylindrical body with refrigerant vapor inlet and outlet connections and perforated tapered deflectors placed in the upper part of the housing, the bottom end housing is equipped with an oil sump and a coaxially installed separator in it, and the refrigerant vapor inlet introduced into the body through a separator and has a glass at the outlet end with tangential slit nozzles and an end opening, and the oil collector communicates with the upper part of the body stvom equalizing tube snabzhe1 hydrochloric float regulator and fitting for discharging oil.

Figure 1 shows the oil separator; figure 2 - section aa in figure 1.

The oil mill contains a vertical cylindrical body 1 with pipes 2 and 3 for supplying and discharging refrigerant vapor, respectively, as well as pipe 4 for supplying liquid refrigerant. In the upper part 5 of the oil separator, perforated conical bump stops are installed 6. Case 1 at the bottom end is equipped with an oil sump 7 mounted coaxially with housing 1, and coaxial with hull 1 and oil sump 7 in the latter, a separator 8 is installed, and the connector 2 for supplying refrigerant vapor is introduced into the housing 1 through a separator 8 and, at the exit end, has a beaker 9 with tangential slit holes 10 and an end hole 11. The separator 8 is installed coaxially with the refrigerant vapor supply nozzle 2, and a narrow annular gap 12 is formed between them, connecting the lower part 13 of the housing 1 and the oil pan 7.

In turn, the oil sump 7 is in communication with the upper part 5 of the housing 1 by means of a balancing pipe 1A equipped with a float regulator 15 and a fitting 16 for draining oil. A fitting 17 is provided for draining the dirt in the oil sump.

In the lower part 13 of the housing 1, a perforated partition 18 is placed. A hole 1 1 in the glass 9 slides to prevent the creation of a vacuum so that liquid ammonia does not enter the nozzle 2 when the oil separator is stopped.

The oil separator works as follows.

Through the pipe 2 of the refrigerant vapor supply to the lower part 13 of the housing 1 of the oil separator, under the liquid layer, the level of which is maintained through the pipe 4, hot vapors from the compressor are supplied. Bubbling through the liquid, the vapors are washed to remove the oil carried from the compressor. Purified hot vapors pass through the cone bumpers 6, where drops of liquid ammonia are separated from them and flow downwards, and then from the upper part 5 through the pipe 3, ammonia vapors are removed from the oil separator. Liquid

the oil due to poor solubility with ammonia and the difference in specific gravity is lowered into the lower part 13 of the oil separator and through the perforated partition 18 enters the form of a saturated mixture into the annular gap 12 of the separator 8. Upon contact with superheated vapors through the wall of the inlet 2 of the supply, liquid ammonia boils out the mixture, and the clean oil through the annular gap 12 enters the lower part of the cavity with the Inca 7 oil collection. The initially established guaranteed oil level is maintained by the float regulator 15. Due to Erzhanov oil level at the bottom of the oil sump 15 is formed oily water seal, prevents favoring free liquid from flowing from the cavity of the separator 8, a difference in level in the separator and the sump 7 is maintained by the difference in specific gravities of the oil and ammonia. In order to prevent gas counterpressures in the upper steam cavity of the level 15 float level regulator, an equalizing tube 14 is installed. Constant accumulation of oil in the oil separator and flow

it in the oil pan 7 leads to an increase in its level. The float regulator 15 is activated, and the excess oil through the nozzle 16 is discharged from the oil separator. Due to the fact that the movement of oil from the separator 8 into the cavity of the oil collector 7 occurs at a very low speed, the oil settles and solid impurities (dirt) settle to the bottom of the oil collector, from which I7 OSH1 is periodically discharged.

To create a directional motion, 15 liquid ammonia, located in

oil separator, on top of the refrigerant vapor inlet 2 is placed a glass 9 with slit tangential holes 10 on top. When ammonia vapor escapes from them, the oil in the oil separator twists and the oil in liquid ammonia drops to the periphery and wall oil separator

25 flows down to the separator.

Such an embodiment of the oil separator allows maintaining high efficiency of oil separation and oil regeneration, in addition to automating the process of oil release.
