Embodiment
As shown in Figure 1, the utility model comprises the pretreating device 1 of bringing the mouth of a river into, entering water electromagnetic valve 2, topping-up pump 3, reverse osmosis membrane filt 4, high-voltage switch gear 5 and with the after-treatment device 6 at the reverse osmosis produced mouth of a river, one side of this reverse osmosis membrane filt 4 also is provided with condensed water outlet (not shown), this condensed water outlet connects the condensed water discharge equipment 8 that is connected with the condensed water discharge outlet, also be connected with unidirectional condensed water shunting reclamation set 7 between the water-in of this condensed water outlet and topping-up pump 3, the so just feasible water-in that can be diverted to topping-up pump 3 from reverse osmosis membrane filt 4 effusive condensed water parts mixes with water inlet, make water through topping-up pump 3 and reverse osmosis membrane filt 4 once more, thereby improve the utilization ratio of water inlet.This high-voltage switch gear 5 can determine its closure and disconnection according to the hydraulic pressure size at the reverse osmosis produced mouth of a river, when the hydraulic pressure that produces the mouth of a river is lower than 2.8kg/cm
2The time just closed, hydraulic pressure is higher than 2.8kg/cm
2Just disconnect, thereby realize automatic startup-shutdown of the present utility model; This condensed water discharge equipment 8 electrically connects with the output terminal of electric control box 9, and the input terminus of this electric control box 9 is connected with high-voltage switch gear 5.This electric control box 9 is micro-chip or microprocessor, and it can require output one control signal to give condensed water discharge equipment 8 according to the scheduled time, makes it realize semi-closed on schedule and switching open mode.This entering water electromagnetic valve 2, topping-up pump 3 are realized electrically connecting by high-voltage switch gear 5 and power supply respectively simultaneously.Specifically ask for an interview electrical control figure of the present utility model, promptly shown in Figure 3.
Condensed water discharge equipment 8 of the present utility model is multifunctional electromagnetic valves, and there is kapillary its inside, is in semi-closed state during outage, is in open mode during energising, so just makes the utility model generally be in repeated open and semi-closed state.When semi-closed, control a spot of condensed water discharging; When opening, the supersalinity water that unidirectional condensed water shunting reclamation set is shunted reuse for more than 7 time emits, and plays the effect of flushing reverse osmosis membrane filt 4 simultaneously.
Topping-up pump 3 in the utility model can adopt the voltage regulation type topping-up pump, also can adopt self-priming topping-up pump, or other can play the topping-up pump of supercharging.
Unidirectional condensed water shunting reclamation set 7 in the utility model adopts unidirectional adjustable fluid flow metered valve, and this unidirectional adjustable fluid flow metered valve band tensimeter, and this manometric pressure is 4.4kg/cm
2--4.8kg/cm
2Between, can regulate the flow of this unidirectional adjustable fluid flow metered valve by this tensimeter.
Flow parameter (water temperature 25 degree) with 200 gallons of main accessories of reverse osmosis water purification machine illustrates control method of the present utility model in conjunction with the accompanying drawings below:
| The reverse osmosis membrane specification | Topping-up pump | The condensed water discharge equipment | Unidirectional condensed water shunting reclamation set |
| 200 gallons | 1.95L/min(0.5MP) | 300ml/min | 1200ml/min |
The selection ground of flow is as follows: the unit capacity of topping-up pump is pressed 4 times of selections of reverse osmosis membrane filt specific yield; Condensed water discharge equipment flow is selected by 0.6 coefficient (the selecting integer) choosing of reverse osmosis membrane filt specific yield, i.e. condensed water discharge equipment flow=reverse osmosis membrane filt specific yield * 0.6; Unidirectional condensed water shunting reclamation set unit capacity is selected by 2.3 coefficients (selecting integer) of reverse osmosis membrane filt specific yield, promptly unidirectional condensed water shunting reclamation set unit capacity=reverse osmosis membrane filt specific yield * 2.3.
As shown in Figure 2, control method of the present utility model is as follows:
A, high-voltage switch gear 5 closures were delayed time after 5 seconds, and the utility model starts (can prevent the switch flase operation like this).
B, at first enter emptying gas working order, at this moment topping-up pump 3, entering water electromagnetic valve 2 start, condensed water discharge equipment 8 is opened, unidirectional condensed water shunting reclamation set 7 is not shunted, air in the reverse osmosis membrane filt is carried out emptying, after the emptying gas time reached the predetermined emptying gas time, condensed water discharge equipment 8 was semi-closed.
C, then enter the system water state, the condensed water part of its system during water state (be in the present embodiment reverse osmosis membrane filt specific yield 60 percent) directly discharged by condensed water discharge equipment 8, and other parts are shunted the water-in that reclamation set 7 is diverted to reverse osmosis topping-up pump 3 by unidirectional condensed water.
D, the water time reach pre-customized water after the time when system, enter the flushing state, this moment, condensed water discharge equipment 8 was by the semi-closed open mode that changes over to, at this moment, the flow resistance of the condensed water of flowing through discharge equipment is zero, thus current will be all from then on path flow through to cause and rush down pressure condition, simultaneously unidirectional condensed water shunting reclamation set 7 is not also shunted, after the predetermined flush time, change the system water state again over to.
E, at high-voltage switch gear 5 periods of contact, except the emptying gas working order during start, be that system water state and flushing state hocket At All Other Times.
F, after high-voltage switch gear 5 disconnects, change the state of quitting work over to, this moment, topping-up pump 3, entering water electromagnetic valve 2 quit work, condensed water discharge equipment 8 changes open mode over to, closes after predetermined flush time again.
When the utility model is produced, the reverse osmosis membrane filt of different size will be selected the condensed water discharge equipment and the unidirectional condensed water shunting reclamation set of different flow for use, in addition according to the influent quality situation, the utility model system water state is also different with flushing state time scale, thereby needs pre-customized water time of corresponding adjustment and predetermined flush time.
By adopting above-mentioned control method, reverse osmosis water purification machine is under the situation that guarantees the effluent quality and the water outlet water yield, and moving row is more reliable, and is safer, and the accessory life-span is more permanent.
