Abstract

The invention discloses a foam metal filtering spiral type oil separator. The foam metal filtering spiral type oil separator comprises an outer barrel with the top provided with a gas inlet connector and a gas outlet guide tube, wherein the interior of the outer barrel is divided into a spiral gas inlet cavity, a filtering cavity and an oil collecting cavity from top to bottom; the bottom end of the gas outlet guide tube stretches to the bottom of the filtering cavity, and the bottom end face of the gas outlet guide tube is sealed; a spiral guide blade is arranged in the spiral gas inlet cavity; an annular three-layer foam metal filtering layer is arranged in the filtering cavity, and a circulating hole is formed in the gas outlet guide tube in the foam metal filtering layer; a partition plate is arranged on the top face of the three-layer foam metal filtering layer, and the bottom face of the three-layer foam metal filtering layer is arranged on an annular oil falling umbrella; the three-layer foam metal filtering layer and the oil collecting cavity are separated by the annular oil falling umbrella; a center hole is formed in the center of the annular oil falling umbrella, an oil guide tube is arranged on the edge of the annular oil falling umbrella, and an oil falling hole is formed below the annular oil falling umbrella; an oil outlet is formed in the center of the bottom face of the oil collecting cavity. According to the foam metal filtering spiral type oil separator, the content of large oil drops in air flow is reduced through the spiral guide blade, then the oil drops are effectively intercepted with the three-layer foam metal filtering layer, and therefore the gas-oil separating effect is improved.

Description

technical field [0001] The present invention relates to an oil separator, and more specifically relates to a device installed between the outlet of the compressor and the inlet of the condenser in the refrigeration system, which can separate and recover the oil droplets mixed in the high-pressure gas . Background technique [0002] In the refrigeration system, the compressed refrigerant is in a superheated state of high pressure and high temperature. Because of its fast flow rate and high temperature when it is discharged, and part of the lubricating oil on the cylinder wall is inevitably discharged into oil vapor and oil droplets and particles together with the refrigerant vapor due to the high temperature. The oil separator is a device installed between the compressor outlet and the condenser inlet of the refrigeration system, which can separate and recover the oil droplets mixed in the high-pressure mixed gas. [0003] According to the principle and internal structure, ...
