Cyclone oil-gas separator for multi-online system

Abstract

The invention discloses a cyclone oil-gas separator for a multi-online system. The cyclone oil-gas separator comprises a main cylindrical barrel, a tangential inlet pipe is arranged on the upper side wall of the main barrel, a vertical exhaust pipe is arranged at the top center of the main barrel, the bottom of the exhaust pipe extends into the main barrel, a vertical oil discharging pipe is arranged at the bottom center of the main barrel, the inlet pipe is connected with an exhaust pipe of an air conditioning multi-online system compressor, the vertical exhaust pipe is connected with an inlet of a condenser, the oil discharging pipe is connected with an inlet pipe of a gas-liquid separator, the diameters of the tangential inlet pipe and the vertical exhaust pipe are di and do respectively, the pipe pitch between the tangential inlet pipe and the vertical exhaust pipe is d, d<(di / 2+do / 2), part of fluid led into by the tangential inlet pipe collides with the vertical exhaust pipe, the entered fluid regularly flows around an annular space formed by the vertical exhaust pipe and the main barrel when the fluid flows stably, and oil after being separated is discharged from the cyclone oil-gas separator through the oil discharging pipe. The probability that small oil drops adhere to wall faces and oil drops aggregate is increased by means of inlet gas collision, and accordingly separating efficiency is improved.

Description

technical field

[0001] The invention belongs to the technical field of refrigeration and low-temperature engineering, and in particular relates to a cyclone-type oil-gas separator for a multi-line system. Background technique

[0002] Multi-connectors have an irreplaceable position in the field of central air conditioning. The development of the market has created a demand for multi-connectors with long piping. Since the exhaust gas of the compressor contains more lubricating oil droplets, the separation efficiency of the oil-gas separator directly affects the compressor. The safe operation and service life of the machine, the current engineering practice shows that the oil return problem in the multi-line system is a major difficulty in its design. At home and abroad, the research on the refrigerant-oil in the multi-system of air-conditioning is mostly focused on the distribution and retention of lubricating oil in the system, the change of the macroscopic structure of the ...
