Also match with the locking screw 297 on impeller bearing hub 290 after back-up ring through hole so that the catch turning on locking catch 271
Limit 272 is directed on any one flat limit on two parallel ribs 273, plays locking effect.
Four, flange pressure switch operation principle:
In Fig. 8 to Figure 19, exchanger rotor 740 uses and arranges pressure-exchange passage A-M on rotation round R position, respectively
It is: passage A, passage B, channel C, passage D, passage E, passage F, passage G, passage H, passage J, passage K, passage L, passage M,
Isolation gusset 262 is had to make to isolate between two adjacent passages;Import rotation domatic 922 by low pressure and pressure accumulation imports Rotation Slope
Face 512 and the forward slanted angle of exchanger rotor 740 end face, and rotation domatic 912 is derived in supercharging and release is derived and rotated
Domatic 522 with the reversed dip angle of exchanger rotor 740 end face, just can allow and flange pressure switch segment uniquely moves
Part exchanger rotor 740 rotates freely, and exchanger rotor 740 rotates with per second 20, completes flowing in pressure-exchange passage A-M
Direction switches, it is achieved pressure-exchange.
When the pre-treating seawater in pressure-exchange passage A-M is respectively at and low pressure runner together with the pressure accumulation sea water that dams
742 and during pressure release runner 752 same position, the pre-treating seawater of 0.2 MPa (MPa) pushes the pressure accumulation sea water that dams of atmospheric pressure
Flow downwardly among pressure release runner 752;
When the pre-treating seawater in pressure-exchange passage A-M be respectively at together with the pressure accumulation sea water that dams with supercharging runner 741 and
During pressure accumulation runner 751 same position, the pressure accumulation sea water that dams of 5.8 MPas (MPa) pushes pre-treating seawater, is injected up in supercharging
Heart round 732;The pre-treating seawater being possessed 5.8 MPas (MPa) by exchange pressure is pressurized impeller of pump by booster pump suction inlet 731
770 suctions by centrifugation power are pressurized to 6.0 MPas (MPa) and flow through volute flange outlet 744 and supercharging bump joint 743 successively,
Finally it is incorporated to high pressure sea water inlet pipe 719.
Five, reverse osmosis seawater desalting Engineering Task process:
Low pressure suction pipe 711 and moisturizing suction pipe 712 are inserted into below pretreatment pool water surface 721 20 centimetres, start high pressure and supplement
Pump 714, is drawn the pre-treating seawater in sea water preprocessing pond 703 by moisturizing suction pipe 712, successively through supplementing high-voltage tube 716, pipeline
After threeway 769 and high pressure sea water inlet pipe 719, it is injected among film intake antrum 718 and directly participates in permeable membrane desalinization;
When the pressure of the pre-treating seawater in film intake antrum 718 reaches 6.0 MPas (MPa), the wherein pressure accumulation sea of damming of 80.1%
Water is dammed by reverse osmosis membrane 720, and wherein the process fresh water of 19.9% penetrates reverse osmosis membrane 720, enters among film water chamber 728, warp
Desalination water goes out pipe 729 and is transported to the stand-by region of fresh water deposit;
Fail to pass through reverse osmosis membrane 720 80.1% the pressure accumulation sea water that dams through film return duct 727, by pressure accumulation bump joint 749
Enter into pressure accumulation runner 751 position, participate in the pressure accumulation sea water experience wave of damming of lower half among pressure-exchange passage A-M
Raising and lowering, rotates to pressure release runner 752 position along with exchanger rotor 740 after pressure release, flows through release bump joint 746,
Emit from drain line 726 or deliver to downstream processes;
Meanwhile, start low pressure lift pump 722, low pressure suction pipe 711 draw the pretreatment sea in sea water preprocessing pond 703
Water, successively after low pressure line 723 and low pressure bump joint 747, is injected into low pressure runner 742 position, participates in pressure-exchange
Among passage A-M, the pre-treating seawater experience wave raising and lowering of the first half, rotates along with exchanger rotor 740 after supercharging
To supercharging runner 741 position, flow through supercharging bump joint 743 and pipeline threeway 769 successively, after being incorporated to high pressure sea water inlet pipe 719,
It is injected among film intake antrum 718 and directly participates in permeable membrane desalinization.
Owing to exchanger rotor 740 rotates with per second 20, the pre-treating seawater among pressure-exchange passage A-M with dam
Between pressure accumulation sea water, contact surface can produce blending, learns that blending amount only accounts for participation reverse osmosis membrane 720 amount of work 1% after tested.Increase
Manage blue pressure-exchange and promote pump, the pressure accumulation sea water that dams of fail to pass through reverse osmosis membrane 720 80.1% is obtained efficient recovery
Utilize, reach the effect of energy-saving and emission-reduction.
The above-mentioned prominent substantive distinguishing features of the present invention, it is ensured that can bring the most progressive following effect:
Low pressure lift pump 722 only needs to bring up to the pressure accounting for the pre-treating seawater participating in reverse osmosis membrane 720 amount of work 80.1%
0.2 MPa (MPa), so that it may complete there is the pressure accumulation sea water that dammed of 5.8 MPas (MPa) to realize pressure in film return duct 727
Exchange, it is ensured that disc type I type explosion separation motor 710 only needs the pressure of the pre-treating seawater by accounting for amount of work 80.1% again from 5.8 MPas
(MPa) 6.0 MPas (MPa) are brought up to;The segmentation accounting for the pre-treating seawater participating in reverse osmosis membrane 720 amount of work 80.1% improves
In pressure differential only have 0.46 MPa (MPa);The acquisition fresh water penetrating reverse osmosis membrane 720 accounts for participation reverse osmosis membrane 720 total working
Amount 19.9%, account for participate in reverse osmosis membrane 720 amount of work 19.9% pre-treating seawater through high pressure make-up pump 714, from atmospheric pressure
Directly bringing up to 6.0 MPas (MPa), energy-saving effect is obvious.
