Abstract
The invention provides a wheel type pressure exchanger which basically comprises a rotor with a radial hole, a rotor shell with a plurality of holes, a high-pressure side end cap and a low-pressure side end cap, wherein the rotor is capable of rotating by the aid of the impact force of fluids. When the rotor rotates to a pressure exchange position, a high-pressure fluid A presses out a low-pressure fluid B in the radial hole of the rotor, so that pressure is exchanged from the fluid A to the fluid B. When the rotor continues rotating to a next position, namely, a fluid replacement position, the low-pressure fluid B presses out the fluid A in the radial hole of the rotor and discharges the fluid A from a discharge port, so that the fluid A and the fluid B in the radial hole are exchanged. When the rotor continues rotating back to the original pressure exchange position, a pressure exchange and fluid replacement cycle is realized. In the cycle, an interlayer is constantly reserved between the fluid A and the fluid B, so that the fluid A and the fluid B are not mixed.
Description
Technical field
The present invention relates to the pressure exchanger between the fluid of 2 kinds of different pressures in a kind of fluid system, it can carry out the pressure-exchange between the high and low pressure fluid, thereby reaches the purpose that reduces energy consumption.
Background technique
Carried out a lot of years for the complex art of fluid pressure energy and the research of equipment both at home and abroad at present, also in succession developed numerous multi-form devices.
Pressure fluid total energy approach equipment basic condition is as follows at present:
Present pressure fluid total energy approach equipment (pressure exchanger or energy recycle device) has hydraulic turbine formula energy recycle device and Work-exchange type energy recovery device two large classes.Energy recycle device the earliest is the hydraulic turbine formula, Pe1 ton Whee 1 turbine engine of Switzerland Calder.AG company and the Francis turbine engine of Pump Ginard company, efficient is generally 50%-70%, its principle is to utilize brine to drive turbine rotation, link to each other with motor with pump by axle, to the former seawater of charging, process need is through " water pressure energy---mechanical energy---water pressure energy " two steps conversion with Energy transfer.Process is improved on the superincumbent basis, the design of some uniquenesses has appearred, wherein directly to drive the Hydraulic Turbochargero that pump and U.S. PEI company produce all be turbine and pump integrated design to the representative BMET turbine that has Denmark Grundfos company to produce, a rotating shaft connects two impellers, all be encapsulated in the housing, impact blade when brine flows through impeller and promote wheel rotation, thereby drive the turbine spindle rotation.Turbine spindle directly drives suction booster work output mechanical work, and dense water transformation of energy becomes the energy conversion efficiency of former seawater can be increased to 65%-80%.High-pressure service pump and turbine suction booster two-stage series connection are finished the boost in pressure of former seawater, reduce the needed lift of high-pressure service pump by the turbine supercharging, reduce motor power consumption.But, owing to all will through " water pressure energy one by one mechanical energy one by one water pressure energy " two steps conversion, increased the mechanical energy loss, so efficient be lower on the hydraulic turbine formula energy recycle device principle.The eighties, a kind of new Energy Recovery Technology has appearred, its working principle is that " merit exchange " is by interface or spacer, directly the pressure of high-pressure thick salt solution is passed to the charging seawater, process is simplified, only need through " water pressure energy is water pressure energy one by one " step transformation of energy, energy recovery efficiency can be improved.The Work-exchange type energy recovery device of using in the reverse osmosis seawater desalting engineering at present is mainly rotator type pressure exchanger and piston valve governor pressure exchanger two classes, and efficient can be up to 90-97%.The rotator type pressure exchanger is take the PX rotator type pressure exchange energy reclaiming device of U.S. ERI company as representative.Principle is that high-pressure thick salt solution promotes the shaftless ceramic rotor rotation that circumference has a plurality of longitudinal grooves (being similar to a plurality of miniature fluid cylinders).Piston valve governor pressure exchanger is take the DYPREX power pressure exchanger of the PES pressure-exchange system of the SalTec DT pressure exchanger of the two merit exchange energy reclaiming devices of the DWEER of Switzerland Calder.AG company, German KSB company, German Siemag Transplan company and Ionics company as representative.Principle is to adopt two major diameter fluid cylinders, the dense water pushing piston of one of them fluid cylinder mesohigh passes to the former seawater of low pressure to exterior liquid with energy, charging pump is pressed into the former seawater fluid infusion of low pressure and discharges low-press thick water in another fluid cylinder, two fluid cylinders are alternately arranged under the control of PLC and dense water selector valve and are mended seawater, realize dense water transformation of energy is become the callback course of former seawater energy.
The critical piece of popular U.S. PX pressure exchanger is a rotor with a plurality of axial holes in the market, rotor is contained in the accurate ceramic jacket of gap size and rotates, axial hole inner high voltage brine current at rotor pass to low pressure fresh seawater current with pressure, these two strands of current are directly contact in the internal channel of rotor, thereby finishes pressure-exchange.At any time, half of rotor internal channel is in the high-pressure water flow, and second half then is in the low pressure water flow.Passage can be by a seal area with high pressure and low pressure isolation when rotor rotated.These contain the passage of high pressure water and the adjacent passage that contains low-pressure water is isolated by the seal area of the partition between rotor channel and the formation of ceramic end cap.The ceramic component schematic representation of PX energy recycle device as shown in the figure.
Flow to the passage in low pressure area left side by the seawater of seawater raw water service pump supply, these current are discharged brine from the right side of passage.After rotor turned over seal area, high pressure brine increased pressure from the right side flow channel to seawater, the seawater behind the pressurized and then inflow recycle pump.Rotor whenever revolves and turns around, and this pressure-exchange process just repeats in each passage, thereby constantly has current to inject and discharge.
Some efficient of above-mentioned pressure exchanger lower (such as the hydraulic turbine formula), some flow that can not export have larger fluctuation (such as piston valve governor pressure exchanger), some can not export larger flow (such as PX rotator type pressure exchanger), and this all has certain narrow limitation in the application of reality.
