Abstract

The invention provides an oil separator which comprises a casing provided with an inner cavity, wherein an oil inlet, an oil outlet and a first oil returning opening are formed in the casing; a sealing plate and a porous baffle are connected to the inner wall of the casing; the inner cavity is divided into a first space communicated with the oil outlet and a second space communicated with the oil inlet, as well as a third space communicated with the first oil returning opening by the sealing plate and the porous baffle; a middle channel for communicating the first space with the second space is arranged on the sealing plate; an oil-gas separating part is arranged between the oil inlet and the porous baffle; the oil separator also comprises a first filter which is in a hollow round shape; the first filter is arranged in the first space; the inlet of the first filter is communicated with the middle channel. According to the oil separator provided by the invention, the first filter is arranged above the sealing plate; under the condition that the existing structure is not changed, the filtering times is increased; a fine filter adopts a filtering mode of inside-entering and outside-exiting, so the filtering area is increased, and the filtering effect is improved.

Description

technical field [0001] The invention relates to the field of separators, in particular to an oil separator for efficiently separating mixed lubricating oil and refrigerant. Background technique [0002] At present, most of the oil separators in the refrigeration system adopt the combination of centrifugal separation and filter separation. By installing a sealing plate in the middle of the oil separator, it is divided into the upper filter space and the lower separation space. The mixed gas of refrigerant and lubricating oil discharged from the compressor enters the oil-gas separation space through the oil inlet and is centrifuged. Part of the gas enters the filter space through the space provided on the sealing plate for filtration, and then is discharged through the oil outlet. For this kind of oil, the problem is: the filter area is small, and the filter effect is not good enough. Contents of the invention [0003] In order to overcome the deficiencies of the prior art,...
