High-efficiency oil separator

Abstract

A high-efficiency oil separator comprises a main barrel, an air inlet hole and an air outlet hole, wherein the air inlet hole and the air outlet hole are formed on side walls of two ends of the main barrel, a front seal board and a rear seal board are installed at the two ends of the main barrel, and an oil separation blocking barrel, a filter barrel and a spiral piece are installed inside the main barrel and are communicated in sequence. The high-efficiency oil separator is reasonable in structure. By means of reasonable matching and installation of the main barrel, the air inlet hole, the air outlet hole, the oil separation blocking barrel, the front seal board, the rear seal board, the filtering barrel, the spiral piece, an air outlet gap, an oil gathering pocket and other components, gravity, collision, centrifugation, rotation, filtration, wall attachment effect, gyroscopic effect and other principles are used reasonably, supplementation is conducted, effective separation of high-pressure high-temperature mixture of gas-state refrigerant and fluid oil can be achieved inside the high-efficiency oil separator, and oil separation efficiency can achieve 10-5PPM. Besides, the high-efficiency oil separator is compact in whole structure, small in using occupied space, capable of being directly installed on a machine set during installation and using, and is simple and convenient to use.

Description

technical field

[0001] The invention relates to a separation device, in particular to an oil separation device in a refrigeration system, in particular to a high-efficiency oil separator used in a refrigeration unit to separate lubricating oil and gaseous refrigerant. Background technique

[0002] In the vapor compression refrigeration system, when the compressor is running, the compressed refrigerant vapor (ammonia vapor or freon vapor) is in a superheated state of high pressure and high temperature. Due to the fast flow rate and high temperature when it is discharged, part of the lubricating oil on the cylinder wall of the compressor is affected and affected by the steam, and also affected by the structural volume factor of the built-in oil of the compressor, it is inevitable to form oil. Steam and oil droplets are discharged together with refrigerant vapor. And the higher the exhaust temperature and the faster the flow rate, the more lubricating oil will be discharged. ...
