High-Pressure Hydraulic Turbine Energy Recovery Units
The high-pressure hydraulic turbine is a new high-tech product
designed for recovering the remaining energy of High-pressure fluid
in petrochemical plants, which meets the requirements of national
“Technology Policy Outline” and Appendix C of API610-10TH “The
Relevant Provisions of Hydraulic Power Recovery Turbine”. The
device gathers all of the achievements in scientific research of
our company in recent five years, which owns an excellent
application performance, and breaks the foreign monopoly in this
kind of products. The recovery power of a single set of hydraulic
turbine device reaches more than 500kW, which shows an obvious
energy saving. This project has been checked and accepted by
SINOPEC, Technological Innovation Projects of Anhui Province and
Hefei City. The product’s structure has got the patent of invention
“Hydraulic Turbine Device ZL200910144394.7” and utility model
patent “Compound Restrictor Ring ZL201020201422.2”. HG/T “Chemical
Hydraulic Turbine” formulated by our company has been listed in the
Occupation Standard Revision Project of the Ministry of Industry.
The product has been successfully applied for hydrocracker units,
which has replaced the imported product and gained a remarkable
social and economic benefits.
Combination Model of Pump-Hydraulic Turbine Units
Rigid shaft design was adopted in the low-speed turbine, whose
rotor system is highly resistant to forced vibration and
self-excited vibration, and the application range of the turbine
would be wider. Previous petroleum and chemical units were equipped
with high-speed turbines. Because more and more problems occurred
in operation, then the high-speed turbine was replaced gradually by
the low-speed ones recently.
BB5 model horizontal multi-stage double casing with both ends
supported structure is adopted in the turbine, which meets the
requirements of API. Inlet and outlet locate radially in two sides
of the cylinder with two sets of mechanical seal components and
bearing parts attached tightly. Externally forced lubrication oil
station is used in bearings, which meets the severe working
conditions and environments. Condition matching design of impeller
and guide vane suits for the specificity of high_pressure and
easily vaporized medium and increases the recovery efficiency.
Axial force balancing device, which locates in the inlet side, can
balance the axial force due to rotors being arranged in the same
direction. Rotor system has a rigid shaft design, which increases
the strength and rigidity of the shaft and improves the resistant
ability of external disturbance and increases the reliability and
stability of the hydraulic turbine.
This series of pumps use the drum-plate-drum structure for balance,
which can control “Flashing” effectively during operation. Besides,
the structure can completely balance the axial force. When working
in normal conditions, the bearing would not bear the axial force
and increase the life of bearing greatly.
The range of application
Used for hydrofining, hydrocracking and similar occasions in
petroleum refining for High-pressure hydraulic energy recovery. The
payback period of investment will be 9~18 months.
