Description

(54) OIL SEPARATOR

one

The invention relates to refrigeration technology, and more specifically to oil separators for compression refrigeration machines.

Oil separators are known, comprising a housing with a pipe for introducing a steam-oil mixture, liquid and vapor spaces connected respectively to the liquid and steam cavities of the condenser, and a baffle placed in the upper part of the housing 1.

A disadvantage of the known oil separators is their low oil separation efficiency due to the small contact surface of the droplets and oil vapors with the liquid refrigerant.

The purpose of the invention is to increase the efficiency of oil separation.

This goal is achieved by the fact that the oil separator further comprises a liquid circulation loop connecting the liquid space of the housing with its steam space, a pump and a sprinkler installed in series in the loop, the latter being located in the steam space of the housing under the baffle plate.

The drawing is a schematic representation of the previous oil separator.

It contains a housing 1 with a nozzle 2 for introducing a steam-oil mixture, a liquid space 3, a vapor space 4, a baffle 5, a pump 6 and a sprinkler 7, a condenser 8, level holder 9, a receiver 10, a nozzle 11 for releasing the purified refrigerant vapor and

10 valve 12 for draining the separated oil.

The operation of the oil separator is as follows.

Steam oil to the mixture from the compressor through pipe 2 is fed into the housing 1 and irrigated there with a liquid refrigerant, a circulating pump 6 through the irrigator 7. When the oil-vapor mixture comes in contact with the liquid refrigerant, oil drops fall from it, which collect in the lower part of the housing 1, because the specific gravity of the oil is greater than the specific gravity of the liquid refrigerant, mainly ammonia. As the oil accumulates, its oil from the housing 1 through the valve 12. The replenishment of the housing 1 with the liquid refrigerant comes from the condenser 8 through the level holder 9, since
