oil separator

Abstract

The invention provides an oil separator. The oil separator comprises a cylinder body, an air inlet pipe, an air outlet pipe and an oil return pipe. The top of the cylinder body is provided with a first through hole, and the bottom of the cylinder body is provided with a second through hole; the air inlet pipe and the air outlet pipe extend inside the cylinder body through the first through hole and the second through hole respectively; the bottom of the cylinder body is provided with a third through hole, and the oil return pipe extends inside the cylinder body through the third through hole. The oil separator also comprises a filtering device and an oil retaining device which are sequentially arranged inside the cylinder body from top to bottom, the filtering device is arranged at the air outlet end of the air inlet pipe, and the air outlet pipe extends inside the oil retaining device. According to the above structure of the oil separator, the filtering device and the oil retaining device achieve double oil separation, so that the oil separation efficiency is higher and meanwhile the oil storage function can be obtained. By means of a vertical type structure, the oil separator has relatively large capacities, thereby being applicable to large air conditioning systems.

Description

technical field [0001] The invention relates to a separation device, in particular to an oil separator. Background technique [0002] The oil separator is a commonly used gas-liquid separation device; it is one of the necessary components in large and medium-sized air-conditioning systems. It is installed at the exhaust port of the air-conditioning compressor to separate the lubricating oil in the high-temperature gas discharged from the compressor. Through the oil return loop, it returns to the compressor through the suction end of the compressor, so as to ensure the lubrication requirements of the compressor and the operation of the system. [0003] The structure of oil separator generally includes three types: horizontal type, vertical type and straight-through type. Among them, the straight-through oil separator is generally equipped with a filter screen to filter and separate the lubricating oil in the oil-gas mixture, and the oil separation efficiency is high. However...

Problems solved by technology

[0004] Based on this, it is necessary to provide a solution for the problem that the straight-through oil separator has high oil separation efficiency but is not suitable for large and medium-sized air conditioning systems, while the vertical oil separator is suitable for large and medium-sized air conditioning systems but has low oil separation efficiency. oil separator
