Flow of Gas-Liquid Piping System:
The flammable gas comes from the upstream flows into the compressor
after purified by scrubber, and then mixed with injected coolant
during the compression process, and the gas-liquid mixture will be
discharged flows into the separator after compression and cooling.
The separated flammable gas enters into downstream piping network
as well as separated coolant re-injected into compressor internal,
doing the closed circulation in this way.
Process of lubricant piping system:
Lubricating oil in lubrication oil tank pressurized into the main
oil pipeline by lubricant pump, passing through the filter and the
cooler entering the oil distributor before divided into several
ways to the corresponding lubricating point of the compressor. Then
flow back to the oil tank through oil return pipe, and the closed
circulation is finished.
This type of screw compressor unit is specially designed for biogas
Power generation etc.
This is biogas screw compressor, the gas is biogas, and it’s a case
The byproducts such as vinasse left after brewing can be anaerobic
fermented to biogas, which can be used for electricity generation.
This compressor is professionally designed for recycling biogas,
pressurize the biogas to meet the electricity generation of the
downstream gas turbine. The unit effectively using the resources
such as biogas, to solve the electricity problems of the group
company , even can feed electricity into the state grid. It’s the
important equipment in the typical "turning waste into treasure"
project, and a new type screw compressor set meet the calling of
the national "energy saving".

1. It’s a wet screw compressor, safe and reliable. It’s cooled by injected liquid to maintain a
lower temperature in the compression chamber.
2. Compressor is acting continuously make the outlet pressure
3.It has few wearing parts, reliable operation ,long service life
and low maintenance cost.
4. High automation, the operators do not need professional training
for a long time, and the unit can unattended operating.
5. Low vibration, the compressor can run steady with high speed, no
foundation is realized.
6. Small size, light weight and small occupation area.
7. The effects of volume flow is almost free from the discharge
pressure for the characteristics of gas forced transmission,
keeping high efficiency in wide range. In circumstances of no
changes of the compressor structure, it is suitable for many
8. Baosi water-inject screw compressor is equipped with mechanical
seal, to ensure the separation of gas-liquid system and lubricant
oil system, so as to avoid the substances in the gas-liquid system
entering the bearing lubrication oil system. Make sure the
compressor running reliably.
9. Baosi screw compressor can be equipped with pre- and post
processing system, making the operation more stable and make the
compressed gas cleaner.
