Embodiment
As shown in Figure 1-Figure 3, the utility model is made up of controller 2, desalination system and constant pressure water supply system; Desalination system is made up of raw water pump 1, more medium filter 3, accurate filter 4, motor 5, surge tank 6, high-pressure pump 7, membrane module 8 and cleaning water tank 9; Constant pressure water supply system is made up of pure water tank 10, constant pressure water supply pump 11 and constant-pressure tank 12;
Raw water pump 1, more medium filter 3, accurate filter 4, high-pressure pump 7, membrane module 8 are connected in order successively with cleaning water tank 9;
Pure water tank 10, constant pressure water supply pump 11 and constant-pressure tank 12 connect successively in order by;
Controller is connected with liquid level switch 21 with raw water pump 1, low-voltage variation 15, electrical ball valve 16, magnetic valve 17, motor 5, conductivitimeter 19, online tensimeter 13, constant pressure water supply pump 11 respectively by electric wire.
Online tensimeter 13 and manual ball valve 14 is provided with in the middle of raw water pump 1 and more medium filter 3; More medium filter 3 has two, is connected with an online tensimeter 14 respectively on right side by electric wire; Low-voltage variation 15, online tensimeter 14 and electrical ball valve 16 is disposed with in order between accurate filter 4 and high-pressure pump 7; Upper end is connected with an online tensimeter 14; Magnetic valve 17 and manual ball valve 14 is connected with by electric wire below electrical ball valve 16; The upper end of high-pressure pump 7 is connected with motor 5; Right-hand member is connected with surge tank 6.
Connect by having sampling valve 18, conductivitimeter 19 and under meter 20 in order successively between membrane module 8 and cleaning water tank 9; The upper and lower two ends, right side of cleaning water tank 9 are respectively arranged with two liquid level switches 21; Online tensimeter is provided with between constant-pressure tank 12 and constant pressure water supply pump 11.
When filtering sea, seawater first gets rid of the particulate matter that particle diameter is greater than 5 μm after two more medium filters 3 and accurate filter 4, is sent in membrane module 8 and carries out reverse osmosis process after then being pressurizeed by high-pressure pump 7; The unboiled water of output first enters into constant-pressure tank 12 after cleaning water tank 9; It is out of service that pressure in constant-pressure tank 12 reaches a certain amount of rear equipment.When needs supply water, constant pressure water supply pump 11 starts, install online tensimeter 13 in pipeline, pressure size in perception pipeline, feedback signal changes the rotating speed of pump motor after micro computer calculates, change the flow or pressure that supply water, thus saves energy and water saving significantly.
The Function and operation that all parts of the present utility model has oneself indispensable, accurate filter generally arranges the accurate filter that filtering accuracy is 5 μm, its effect retains the particle being greater than 5 μm that unboiled water brings, and enters reverse osmosis system to prevent it.This particle may puncture reverse osmosis membrane assembly after high-pressure pump is accelerated, and causes a large amount of situation of leaking salt, scratches the impeller of high-pressure pump simultaneously.
The effect of high-pressure pump is for reverse osmosis body apparatus provides enough intake pressures, ensures the normal operation of reverse osmosis membrane.According to the characteristic of reverse osmosis itself, certain row's power need be had to go to overcome the resistances such as osmotic pressure, and guarantee reaches the water production rate of design.
Membrane module is topmost desalting plant in native system, and membrane module utilizes the characteristic of reverse osmosis membrane, and except anhydrating, middle most of soluble salt is divided, colloid, organism and microorganism.Unboiled water qualified after pre-treatment enters membrane module, and the small-molecular-weight organism of water molecules and minute quantity, by rete, after conduit is concentrated, to reinject cleaning water tank towards water producing pipe.Otherwise intransitable just concentrated rear towards concentrated water discharge pipe via another group conduit, backwash water tank can be discharged to, also can directly discharge.The water inlet of system, produce on water and dense waterpipe and a series of by-pass valve control, monitoring instrument and program control operation system are all housed, the systematize of the equipment of guarantee energy long term guarantee quality, guarantor's amount runs by they.
The effect of cleaning water tank is exactly add various medicament, and accelerate treating processes, optimizing pending water quality, is that the operation that treating processes is quick, stable is gone down.
The medicament mainly added has following several:
Flocculation agent: flocculation agent mainly utilizes its aggregation property to be that particle in water or particle are concentrated, and constantly increase the volume of flco, these flcos are removed by recycling action of gravity, reach the object of purifying waste water.Generally adding before the filter, is after producing larger flco in water body, accelerates filtration intercept process and the efficiency of strainer.
Sterilant: sterilant is mainly used to remove microorganism in water and algae etc., avoids follow-up activated charcoal filter and reverse osmosis membrane generation biological pollution.Generally mainly add before the filter, mainly kill the microorganism in water, prevent microorganism from forming biological pollution on gac and film, system is damaged.
Scale inhibitors: Scale inhibitors effect is before unboiled water after pretreatment enters reverse osmosis, adds high efficiency scale inhibitor special, produces fouling to prevent reverse osmosis concentrated water side.Before being mainly added in tight strainer, for regulating the insoluble inorganic salt in disperse water, prevention or disturbing the precipitation of insoluble inorganic salt on film surface, fouling, reduce film properties, influential system treatment effect.
Reductive agent: being generally added in single-stage reverse osmosis import or two-pass reverse osmosis entrance, in order to regulate feed water by reverse osmosis pH value, preventing reverse osmosis membrane fouling, protection reverse osmosis system.
Constant pressure water supply system with pipe network water pressure (or user's discharge) for setup parameter, automatically the rotating speed of pump motor is regulated by the output frequency of microcomputerized controller, realize the closed loop adjustment (PID) of pipe network water pressure, make waterworks automatic constant surely in the force value set: when namely water consumption increases, frequency raises, pump rotary speed is accelerated, the corresponding increase of service discharge; When water consumption reduces, frequency reduces, and pump rotary speed slows down, and service discharge is corresponding reduction also, this ensures that theres the requirement of water application efficiency user to hydraulic pressure and the water yield, reaches the object improving water supply quality and water application efficiency simultaneously, " using how much water, for how much water ".
Desalination and water supply are integrated into an equipment by the utility model, reduce the trouble on user's buying and place apparatus, and waterworks saves water, electricity, for client decreases cost greatly, two equipment integration one, control with same controller, simplify operation, very convenient during use, the most important thing is to adopt this equipment to desalinize seawater does not need to build elevated tank, water tower, water quality non-secondary pollution.
Above-mentioned embodiment is not to restriction of the present utility model; the utility model is also not limited in above-mentioned citing; the change that those skilled in the art make within the scope of the technical solution of the utility model, remodeling, interpolation or replacement, also all belong to protection domain of the present utility model.
