Embodiment
Figures 1 and 2 show that the pressure exchanger for pressure to be transferred to low-pressure fluid from high-pressure fluid.The pressure
Exchanger includes the rotor 300 of body 100, the sleeve 200 being arranged in body 100 and the internal rotation of sleeve 200, the body
100 include 2 strong brine water inlet pipes (121,122) and 2 pressurised seawater outlet pipes (111.112), and 2 seawater enter
The mouth of a river (113.114) and 2 strong brine delivery ports (123,124), 8 paths 201 on sleeve 200 respectively with the water pipe
(121,122,111,112,113,114,123,124) it is aligned, is formed and sealed with O-ring by the groove 202 on sleeve 200, when
Rotor 300 in 200 internal rotation of sleeve, the access portal 302,303 of rotor 300 respectively with 8 paths 200 on sleeve 200
Partly or entirely alignment, the body 100 also include 2 end caps (130,140), tighten fixation by screw hole 150, make machine
Body 100 forms a closed cavity.Using the pressure exchanger, by rotation of the rotor 300 in the sleeve 200,
Pressure is transferred to low-pressure fluid from high-pressure fluid.
For example, in running, the high pressure brine of reflexive osmosis operation is fed in the future under e.g., from about 550psig pressure
Import water pipe (121,122) at the upper end of device, supplies low pressure seawater under about 30psig pressure, is fed to by pumping
Water inlet pipe (113.114) at the lower end of device, the liquid flow that import water pipe (121,122) enters can turn round outer rotor, such as
Well known in the art, most of driving force is provided by high pressure brine.High pressure brine is from import water pipe (121,122)
Into the access portal 303 of rotor 300, when rotor turns round into the upper end of each passage 320 on rotor, highly pressurised liquid is supplied
To the passage communicated therewith；This causes the liquid of same amount of such as seawater to be entered under about 30psig pressure by seawater simultaneously
The mouth of a river (113.114) enters the access portal 302 of rotor 300.The discharge stream for the second liquid (i.e. seawater) being now pressurized enters sea
Water outlet pipe (111.112).The discharge stream for completing the high pressure brine (effluent brine) after pressure transmission simultaneously enters strong brine water outlet
Mouth (123,124)., it is evident that rotor 300, which returns to turn around, can complete 2 pressure-exchanges, and process as described above is certainly
It is dynamic ad infinitum to repeat.Said process recurs for the multi-channel 320 in rotor 300.In each passage 320
Also several passage aisles 310, passage aisle structure can be that circle can also be cellular and rhombus, and all are advantageously reduced
The mixing of strong brine and seawater, and the planform of the increase structural strength of rotor 300, diaphragm can also be provided with or be slidingly sealed
Part, to avoid the contact between two kinds of fluids.
It will be appreciated by persons skilled in the art that for the body 100 part relative to the body 100 its
The fixation and sealing of his part, various methods can be used, and the above method is within the scope of the present invention.
With reference to figure 4 and Fig. 5, between multiple similar passages 320 in the rotor 300 are around radiuses such as rotary shafts and angularly
It is distributed every ground.
Show that the inside of 200 entry of sleeve 203 is bent with reference to figure 3, the bending can be random angle, it is therefore an objective to draw
Baffle impact rotor 300, driving rotor 300 rotate.
The driving force of the rotor 300 can be fed or substituted by machinery and/or electric power means.
Show that the periphery of rotor 300 has groove 301 with reference to figure 4, the storage for lubricating fluid.
The rotor 300 and sleeve 200 can make of pure ceramic-like high-abrasive material, can also use metal or nylon etc.
Material in friction surface coating or bushing ceramic-like high-abrasive material by being made.
Further, the pressure exchanger is more inlet and multi-exits, and entry and vent pathway are circumferentially equal respectively
Cloth, and entry and the logical circumferentially arranged for interval of discharge, it is the integer of the port number described in preferred embodiment
The port of multiple is within the scope of the present invention, such as three enter three and go out or four enter four and go out.The structure of more inlet and multi-exits can be with
Significantly improve and exchange frequency and increase single-machine capacity, this is highly profitable to seawater desalination system, can also make rotor radial
Uniform force, smooth running.
