Detailed description of the invention

In Fig. 1, direction shown in arrow is the flow direction of water.

As Figure 1-4, electrostatic desalination system, including water tank inlet 1, demineralizer 2 with go out water tank 3, water tank inlet 1 And connected by inlet pipeline 4 between demineralizer 2, demineralizer 2 and going out is connected by outlet pipeline 5 between water tank 3, enters Being disposed with water pump 6 and fluid flowmeter 7 by liquid communication direction in water lines 4, demineralizer 2 connects has electrical conductivity to survey Determine instrument 8；Demineralizer 2 includes the shell body 9 in rectangular structure being made up of lucite, and shell body 9 left and right sides is respectively Offering water inlet 10 and outlet 11, water inlet 10 is connected with inlet pipeline 4, and outlet 11 is connected with outlet pipeline 5, Some parallel and spaced battery lead plate 12 it is provided with, the opposite polarity of adjacent two electrode plate 12 and up and down in shell body 9 Being crisscross arranged, each battery lead plate 12 is alternately connected on roof and the diapire of shell body 9, uses external direct current when the present invention works Regulated power supply is as the energy source of battery lead plate；By the positive pole of D.C. regulated power supply and the battery lead plate being connected to shell body 9 roof Connect, the negative pole of D.C. regulated power supply is connected with the battery lead plate being connected to shell body 9 diapire；Battery lead plate 12 includes by rustless steel The rectangular steel plates 13 that material is made, rectangular steel plates 13 two sides are all bonded with NACF by conductive epoxy layer 14 Cloth 15, is enclosed with rustless steel steel wire outside active carbon fiber fabrics 15, rectangular steel plates 13 uniformly offers some circular holes 16, circle Being equipped with silk thread in hole 16, silk thread interts to sew up described active carbon fiber fabrics 15 alternately through described each circular hole about 16 and is close to In rectangular steel plates 13.Rustless steel steel wire, silk thread and D.C. regulated power supply are the existing conventional techniques of this area, in figure not Indicate rustless steel steel wire, silk thread and D.C. regulated power supply.

The applied voltage of every electrode plate 12 is 1.5 volts, and the spacing between adjacent two electrode plate 12 is 1.5 millimeters.

Two or more demineralizer 2 is used to be connected on fluid flowmeter 7 by connecting line 17 and go out between water tank 3, Each demineralizer 2 is respectively connected with conductivity measuring instrument 8.

Wherein water pump 6, fluid flowmeter 7 and conductivity measuring instrument 8 are this area conventional prior, its concrete structure No longer describe in detail.

Measure the test method of the optimal flow of inlet water of electrostatic desalination system: comprise the following steps successively:

(1) along the flow direction of water, the water inlet 10 of first demineralizer 2 is connected with water tank inlet 1 by inlet pipeline 4 Logical, the outlet 11 of first demineralizer 2 is connected with the water inlet 10 of second demineralizer 2 by connecting line 17, The outlet 11 of second demineralizer 2 is connected with going out water tank 3 by outlet pipeline 5, inlet pipeline 4 presses liquid stream Logical direction installs water pump 6 and fluid flowmeter 7 successively, is connected with demineralizer 2 by conductivity measuring instrument 8；

(2) start water pump 6, regulate water pump 6 according to the registration of fluid flowmeter 7 and control flow of inlet water, by flow of inlet water control Make at the predetermined flow value of testing crew, after flow of inlet water is stable, writes down the numerical value on fluid flowmeter 7, pass through electrical conductivity The electrical conductivity of current in demineralizer 2 monitored by analyzer 8, the electrical conductivity of current in a minute records demineralizer 2, and Make electrical conductivity versus time curve figure；

(3) performing a step (2) is a flow test, regulates water pump 6, makes flow of inlet water and new predetermined amount of flow value Adapting, the operation then repeating to continue executing with step (2) carries out flow test, amounts to and carries out three flow tests；This enforcement In example, three flow values are set as 20 L/h(l/h successively), 30 L/h and 40 L/h, by the electrical conductivity of three flow tests Versus time curve figure is plotted on a table and obtains Fig. 5, as shown in Figure 5, as flow of inlet water 20 L/h, at first 5 points The clock walkthrough stage, water outlet conductivity by 135 μ S/cm(microseconds/centimetre) drop sharply to 28 μ S/cm, detect hardness (with CaCO3 counts) by 181 mg/L(mg/litre) dropping to 25 mg/L, during by 45 minutes, water outlet conductivity rises to 135 μ S/ Cm, identical with former water conductivity, hereafter water outlet conductivity almost no longer changes, and illustrates that demineralizer 2 no longer has desalination effect, Need to carry out backwash and regeneration；

(4) perform step (2) to carry out flow test and all obtain electrical conductivity under particular flow rate and change over curve chart every time, Change over curve chart eventually through electrical conductivity under relatively different flow of inlet water, draw optimal flow of inlet water.

In step (2), after the electrical conductivity monitored when conductivity measuring instrument 8 is gradually increasing, demineralizer 2 lost efficacy, and disconnected The voltage applied on battery lead plate 12, is directly passed through former water in demineralizer 2 and carries out backwash.

Active carbon fiber fabrics 15, when work uses, is first bonded in by this utility model by conductive epoxy layer 14 Rectangular steel plates 13 two sides, use silk thread to be located in the circular hole 16 of rectangular steel plates 13, and silk thread is alternately through described each circular hole 16 The interspersed stitching by described active carbon fiber fabrics 15 in left and right is close in rectangular steel plates 13, uses rustless steel steel wire to be wrapped in activity Play fastening and protective effect outside carbon fiber sheet 15, make battery lead plate 12, then parallel for many electrode plate 12 and interval are set Put in shell body 9, the opposite polarity of adjacent two electrode plate 12 and being crisscross arranged up and down, and make each battery lead plate 12 alternately connect Being connected on roof and the diapire of shell body 9, the spacing between adjacent two electrode plate 12 is set to 1.5 millimeters, makes desalination dress Put 2 so that current W-shaped between battery lead plate 12 (fold-line-shaped) flowing flowed into from water inlet 10, in every electrode plate 12 The voltage of upper applying 1.5 volts；Water inlet 10 and the outlet 11 of demineralizer 2 are passed through inlet pipeline 4 and outlet pipeline 5 respectively With water tank inlet 1 and go out water tank 3 and be connected, inlet pipeline 4 is provided with water pump 6 and fluid flowmeter by liquid communication direction 7, demineralizer 2 connects and has conductivity measuring instrument 8；Start water pump 6, regulate water pump 6 according to fluid flowmeter 7 and control feed water flow Amount, after flow of inlet water is stable, is write down the numerical value on fluid flowmeter 7, is monitored in demineralizer 2 by conductivity measuring instrument 8 The electrical conductivity of current, and record electrical conductivity and be worth over time, and make electrical conductivity versus time curve figure；Pass through Regulation water pump 6 changes flow of inlet water, and writes down the numerical value of fluid flowmeter 7, carries out test of many times, thus draws optimal feed water flow Amount.

In above process, the electrical conductivity monitored when conductivity measuring instrument 8 is too high, does not reaches when requiring, is then desalination Device 2 lost efficacy, and needed to carry out backwash and regeneration, now disconnects the voltage applied on battery lead plate 12, is passed directly into former water and carries out instead Washing, water outlet is high concentration water, non-secondary pollution, can directly discharge or recycle.When needs improve desalination effect further Time really, multiple demineralizer 2 of can connecting.

Shape of the present utility model, material, structure etc. are not made any pro forma restriction, every foundation by the present embodiment Any simple modification, equivalent variations and the modification that above example is made by technical spirit of the present utility model, belongs to this reality Protection domain by new technique scheme.
