Abstract

Disclosed are an oil separation device, a screw compressor and an air-conditioning system. The oil separation device comprises an oil separation tank (1) having an inner cavity, and a primary oil separation structure (2) and a secondary oil separation structure (3), which are arranged inside the oil separation tank (1). The inner cavity is separated into a horizontally arranged upstream cavity (6) and downstream cavity (7) by the primary oil separation structure (2), the upstream cavity (6) being provided with a gas inlet (4) in communication with a gas discharge pipe (10) of a compression mechanism, and the downstream cavity (7) being provided with a gas discharge outlet (5) in communication with an inlet of a condenser. The secondary oil separation structure (3) separates the downstream cavity (7) into an upper cavity (71) and a lower cavity (72), the upper cavity (71) having the gas discharge outlet (5).

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to an oil separation device, a screw compressor and an air conditioning system. Background technique [0002] The screw compressor is a semi-hermetic compressor that uses oil and gas mixing to compress. Usually, the screw compressor is equipped with an oil separation device. Since the refrigerant is a mixture of refrigerant and oil droplets when it is discharged from the compressor, the oil separation device needs to be used for oil and gas separation. It can be recycled to reduce the damage to the internal oil circulation of the compressor, so as to save the oil consumption of the compressor. [0003] The oil separation structure of a conventional compressor includes an oil separation barrel. In the oil separation barrel, the oil separation structure composed of porous steel plates sandwiching a filter screen divides its internal cavity into two chambers, upstream and downstrea...
