The invention discloses a splitting type three-stage oil and gas separating device of a
gas compressor, and belongs to the technical field of oil and gas separating. The splitting type three-stage oil and gas separating device comprises a first oil and gas bucket, a second oil and gas bucket and a flow mixing
assembly, wherein a gas outlet of the first oil and gas bucket and a gas inlet of the second oil and gas bucket are communicated by an oil and
gas pipeline; the first oil and gas bucket comprises a first cylinder, a first gas inlet, a first gas inlet protecting plate and a first oil return
pipe; the second oil and gas bucket comprises a second cylinder, an oil separating core, a second gas inlet protecting plate and a second oil return
pipe; the flow mixing
assembly is connected with the first oil return
pipe and the second oil return pipe respectively, and is used for adjusting the flow rate of the second oil return pipe. The splitting type three-stage oil and gas separating device has the advantages that the three-stage separating of mixing gas is realized by the first oil and gas bucket and the second oil and gas bucket, the first oil and gas bucket is used as an
oil storage part, and the second oil and gas bucket is used as a separating part of the oil separating core, and is also used as a
buffer gas tank, so that the filtering accuracy and
operational stability of the
gas compressor are further improved; the size is smaller, the
layout of the
gas compressor is easy, and the installation and maintenance are more convenient and rapid.
