18" Bowl Sludge Dewatering Two Phase Separation Oil Sludge
Centrifuge
For the treatment of oily (waste) water, the purpose is to recover more oil and reduce the oil content in the solid. Therefore, the role of each section in the whole process system is very important.
1. Demulsifier and surfactant can improve the efficiency of demulsification, enhance the subsequent separation efficiency, increase the oil recovery rate, and reduce the oil content in the slag phase.
2. Heating can reduce oil viscosity, improve the oil recovery rate, and lower the solid contents of oil and water.
3. Adding PAM flocculant can increase the solid recovery rate and reduce the solid content in the liquid phase.
4. Separation of oil, water, and slag with the high-efficiency LWS series three-phase centrifuge can improve the separation efficiency, enhance the oil recovery rate, and reduce the oil content of the slag phase.
5. Solid-liquid separation realized by using a high-efficiency LW series two-phase centrifuge can reduce the liquid content of the slag phase, facilitate transportation, and increase the combustion heat value.
Separation performance:
1. About 80~95% oil can be recovered (relating to oil density,
demulsification effect, temperature, etc.), and the recovered oil
can be used for refining purpose after further purified by the
flottweg separator;
2, The water content of the oil phase after separation can reach ≤3
~ 5%;
3, The dryness of the slag phase after centrifugation can reach 40
~ 60%, and its total volume is reduced by over 80% compared to that
before separation;

Technical descriptions of the centrifuge
★ Extremely low infrastructure investment and good on-site operating
environment
Compared with the conventional filter-type equipment
(plate-and-frame filter, belt machine, etc.), the high-performance
centrifuge is compact and efficient, covering only about a third of
land, needless of auxiliary gas source, high-pressure water, and
with simpler pipe structures at the inlet and outlet. Moreover, the
operation environment is more humanized, and the skid-mounted
integrated device has the characteristics of compact structure,
convenient installation, low requirements for infrastructure, and
convenient movement. The centrifuge is widely used in the harmless
treatment of oily sludge in oilfield drilling.
★ Stable operation, low failure rate, and low maintenance cost
Compared with the filter type equipment, the centrifuge does not
require any filter cloth or filter screen, so as to avoid the
trouble of clogging and of replacing the filter cloth. The
operation and maintenance costs of the equipment are low.
★ Modular design, easy to operate
Our design philosophy: To lower the requirements on the skills,
educational level, and labor intensity of operators, and realize
one-button start and stop of the control system, fault
self-diagnosis, and safety self-protection.
★ Operator configuration and labor intensity
The high-performance centrifuge is an automatic and continuous
working mode for feeding-separating-slag (liquid) discharging. The
whole process requires no human intervention. Multiple sets of
equipment require only one inspector (in conjunction with other
positions). Unlike frame and plate-and-frame filter, the slag
discharging process does not require manual cutting, greatly
reducing the labor intensity of the operator.
★ Ingenious, unique, and diversified heavy liquid-phase discharging
structure
The heavy liquid phase separated by the three-phase centrifuge can
adopt two different liquid discharging modes, namely gravity
discharging and discharging through the built-in centripetal pump
with pressure, wherein the latter includes liquid layer fixed mode
and the online adjustable mode of heavy phase liquid layer, which
is selected according to the process conditions.
Double-motor double-frequency conversion common DC bus constant
torque control technology
★ CIP washing system
The fully automatic control system is equipped with a CIP washing
system, which can effectively solve the problem that it is not
completely cleaned during the shutdown process and effectively
avoid the equipment troubles caused by artificial factors.
★ Humanized centrifugal configuration
Spiral bearing (in the drum, concealed) lubrication technology: the
lubricant is filled from the outside of the hood. (Unique
technology in domestic centrifuges) The hood adopts a hinged
opening structure and is equipped with a high-pressure gas strut to
assist the opening.
Vibration and temperature sensor (optional) at the position of the
main bearing housing.
★ Light phase liquid layer adjustment technology
From the current three-phase centrifuge structure for liquid
transportation of centripetal pumps adopted at home and abroad, the
adjustment of the light phase liquid layer requires disassembling
the centrifuge, and replacement takes more than 8 hours. The
centrifuge, with the patented technology of our company, just
requires opening the hood to adjust the light phase liquid layer.
★ Variable pitch technology
Variable pitch technology is a relatively advanced technology in
the world. It can effectively reduce the screw pushing torque,
improve the processing capacity, and further reduce the sediment
water content.
★ Constant torque control technology
The constant torque control of the centrifuge is the most advanced
control mode in the world. The real-time monitoring of the actual
output torque of the constant torque variable frequency motor
through the high-performance auxiliary inverter is compared with
the set torque value, and PID is used to adjust the material
pushing speed of the screw conveyor in real time. The centrifuge
can achieve continuous, stable, and economic operation.
