The high pressure concentrated seawater of reverse osmosis membrane system discharge enters high-pressure thick water cavity via high-pressure thick water inlet (37), then by upper right liquid flow hole
Into right water cavity；In plunger running, the pressure energy of high pressure concentrated seawater passes to the former seawater of low pressure by plunger operation.Together
When, plunger left side current formation thrust, low pressure raw water valve closure, high pressure raw water valve is opened, after the former seawater boost in left water cavity
Enter high-pressure thick water cavity via upper left liquid flow hole, then reverse osmosis membrane system is entered by high pressure raw water outlet (35).
Recuperator is based on Work-exchange type energy recovery principle, and N number of plunger in recuperator is according to certain phase
The reciprocal alternating movement of potential difference, is realized circularly-supercharged；Relative to each valve cycle alternation opening and closing, so as to ensure four water
Intracavitary current are continuous.There is an equilibrium relation in this process：It is assumed that in No leakage, pressure and friction loss ideally,
If low pressure original seawater pressure is P, high-pressure thick seawater pressure is P1, reverse osmosis membrane operating pressure is P2, piston area is A, and system is returned
Yield is R (i.e. the ratio between plunger rod area and ram area), pressure balance formula：P2A=PA+P1A (1-R), then P1=(P2-
P)/(1-R).When high-pressure thick water pressure increases to this equilibrium valve, concentrated water pressure is not further added by, and hereafter will be followed with poised state
Ring is pressurized.
High pressure raw water valve, low pressure raw water valve, high-pressure thick water valve, the Dimension of Valve Plate of low-press thick water valve are omited than corresponding liquid flow hole
Greatly, and face where requiring all liquid flow holes is necessary for plane, it is ensured that no leakage when each valve is closed；When high and low pressure concentrated water valve is beaten
When opening, by thimble high and low pressure raw water valve can be promoted to move in the same direction, so as to reduce the spring connection of high and low pressure raw water valve
The fault rate of mode.
The reverse osmosis seawater desalination system workflow of high-pressure pump comprising recuperator is installed：Former seawater is through water intaking
Pump (26) is lifted into filter (27) and carries out primary filter, is directly entered integral type energy by low pressure original water inlet (36) afterwards
In the recuperator (31) for reclaiming high-pressure pump, reverse osmosis membrane assembly is entered by high pressure raw water outlet (35) after raw water is pressurized
(28), production water is for using, and high pressure concentrated water enters recuperator by high-pressure thick water inlet (37) and carries out remaining energy utilization, and energy is returned
Low pressure concentrated seawater after receipts is discharged by low-press thick water out (38).
At the beginning of high pressure pump startup comprising recuperator, motor drives plunger rod, post by belt drive bent axle, bent axle
Stopper rod drives plunger motion, and power is only motor kinetic energy；After the high pressure concentrated water of reverse osmosis membrane system enters recuperator, then
Plunger motion is promoted by the remaining energy and motor kinetic energy of high pressure concentrated water jointly, it is achieved thereby that remaining energy is recycled, saved
The energy consumption of motor.High-pressure pump comprising recuperator can change belt transport speed by variable-frequency motor, so as to adjust many
The reciprocating frequency of plunger, finally realizes the regulation of output pressure, energy recovery efficiency is up to more than 90%.
