Built-in vertical oil separator for compressor

Abstract

The invention relates to a built-in vertical oil separator for a compressor. The built-in vertical oil separator comprises a barrel body, and an initial air vent and a diversion channel are formed inthe upper part of the barrel body. One end of the initial air vent is connected with the diversion channel, and the other end of the initial air vent is connected with an air vent of the compressor. The diversion channel is connected with a first metal filter screen through a porous screen plate, and a second metal filter screen is arranged under the diversion channel and the first metal filter screen. An umbrella type oil and gas separation baffle plate is arranged under the second metal filter screen. Through four times of oil separation and a layer of oil and gas separation baffle plate, efficient oil and gas separation can be achieved, exhaust gas with very low oil content is provided for a refrigeration system, and the overall efficiency of a system is improved.

Description

technical field [0001] The invention relates to the technical field of compressor oil separation, in particular to a built-in vertical oil separator for a compressor. Background technique [0002] At present, for systems with oil compressors, when the compressor exhausts, the oil will be discharged together with the gas. If the oil separation effect is not good, the oil available for the lubrication and sealing of the compressor will gradually decrease, resulting in compressor failure. At the same time, for the refrigeration system, if a large amount of oil enters the pipeline and condenser with the exhaust, the pressure loss increases sharply, enters the evaporator, and forms an oil film on the evaporation surface, which will cause evaporation. The lower the temperature, the higher the energy consumption, so the effect of a built-in oil separator in a compressor directly affects the efficiency of the system. Contents of the invention [0003] The technical problem to be ...
