More at large explain embodiments of the invention according to drawing.At this, described accompanying drawing schematically shows for the device that produces the salts solution of electrochemical activation by electrolysis.
Device 1 design with reference to the accompanying drawings is used for by group water solution, the especially salts solution of electrolysis production electrochemical activation.For this reason, device 1 comprises electrolytic module 2, can electrolytic medium be input to electrolytic module 2 at inlet side by supply line 4.At this, the softening water of salt solution or aqueous saline solution blending is as electrolytic medium.For this reason, inflow line 4 links to each other with water-softening chemicals website 6 at inlet side.For salt solution is metered in the softening water, Venturi 8 is linked in the inflow line 4, this Venturi links to each other with saline container 10 at the inlet side of itself.In addition,, in the situation of the electrolytic module 2 that is getting around subsequent components during the debug phase (Inbetriebnahmephase) of device 1, the current from water-softening chemicals website 6 can be drained in the saline container 10 by this vent line from intake pipeline 4 vent line 12 that diverges out in water-softening agent website 6 downstreams.Feed in the electrolytic medium for conversion between these running statuses of carrying out with continuously running duty and with predeterminable salt water yield metering, the salt solution that the valve 16,18,20 that is fit to is linked into intake pipeline 4, vent line 12 and access Venturi 8 feeds pipeline 14, and throttling valve 20 is linked into feeds pipeline 14.
At outlet side, discharge for the salts solution of the electrochemical activation that will make in the electrolytic module 2, vent line 24 is connected on the electrolytic module 2.This outflow pipeline is linked in the storage vessel 26 that stores prepared salts solution or anolyte.For the debug phase at device 1 temporarily gets around storage vessel 26, with how divergent directional control valve 28 access vent lines 24, the second outlet of described how divergent directional control valve is connected to flows out on the pipeline 30.
Device 1 is designed for the salts solution of preparation electrochemical activation, this salts solution has in for example medical treatment or pharmacy application directly as sterilizing agent or the particularly advantageous character of antibiotic active substance, especially the free chlorine that has special high-content, preferably surpass 500mg/L or in some cases even surpass 2000mg/L, possess simultaneously high-storage stability.In order to realize these, electrolytic module 2 is by 2 above module compositions and comprise 2 above electrolyzers 40, and these electrolyzers are only described two in an embodiment; But it is evident that, be similar to following embodiment more electrolyzer 40 can also be set.
Each electrolyzer 40 includes the anolyte compartment 42 that forms the first electrode vessel and the cathode compartment 44 that forms the second electrode vessel, and they are all separated from one another by film 46.Then, on the one hand with the anode of delimiting each 42 borders, anolyte compartment and on the other hand to apply voltage between the negative electrode of delimiting each cathode compartment 44 borders, this voltage causes that ion migration passes the film 46 in the middle of being positioned at so that in electrolytic medium contained water at least generating unit divide and dissociate and give birth at least part of dissociating with the salt forelock that the salt solution form is carried secretly.Because the ionic charge in these materials, the described ion migration process that is caused by the voltage that applies causes Cl -And OH -Enrichment and cause H in each anolyte compartment 42 +And Na +Enrichment in each cathode compartment 44.In order to discharge as required the thus hydrogen of enrichment in each cathode compartment 44 or the second electrode vessel, make in cathode compartment 44 every kind of situations to link to each other with gas exhaust duct 47.Described gas exhaust duct forms the exhaust module (in case of necessity with the device that is used for foaming or gas delivery of arranging, for example vortex generator etc. combination) of each cathode compartment 44 in cathode compartment 44.
The device 1 in, the performance desired, high-quality of the salts solution of electrochemical activation especially by in electrolytic module 12 specifically delivery medium stream realize.At this, in the device 1 of embodiment (described device for the overactive anolyte of electrochemistry is provided to some extent adjust), with the negative electrode aspect basically medium flow pipeline in parallel combine with the medium flow pipeline of connecting basically in the anode aspect.Perhaps for unconventional purpose of design, also can with the anode aspect basically medium flow pipeline in parallel combine with the medium flow pipeline of connecting basically in the negative electrode aspect.In addition, can also design other combination of the connection of these medium aspects.
At this, bifurcation point 48 is set in inflow line 4 in the device 1 of embodiment particularly, begin to draw with the form of Parallel Dielectric pipeline the intake pipeline 50 of the cathode compartment 44 that is connected to electrolyzer 40 from this bifurcation point.Outlet side at cathode compartment 44 arranges vent line 52, and this outflow pipeline converges at point 54, thereby obtains generally the parallel connection of cathode compartment 44 aspect medium.
On the contrary, aspect anode, be arranged to anolyte compartment's 42 series connection or the each other front and back connection of anolyte.For this reason, link to each other with the inlet side of follow-up anolyte compartment 42 by connecting pipeline 56 at outlet side in the anolyte compartment that belongs to the first electrolytic module 40 42 of the flow direction of anolyte.This anolyte compartment is connected at outlet side own flows out on the pipeline 24, so that relate to the each other front and back connection of the anolyte compartment 42 of anolyte with the form of implementation realization of multistage or serial mode.
In addition, before the catholyte that device is designed to be flowed out by cathode compartment 44 in 1 imports each other as anolyte in the latter linked anolyte compartment 42.The anolyte compartment 42 of first electrolyzer 40 of seeing on the flow direction of the point 54 that for this reason, makes catholyte by connecting pipeline 58 and anolyte links to each other.
, can be transported in waste water system or the collection container 64 by the shunting that throttling valve 62 is regulated the catholyte of its amounts by this vent line from connecting pipeline 58 vent line 60 that diverges out at point 54.Adopting this to arrange can be transported to adjustable shunting of the catholyte that flows out from cathode compartment 44 series connection that is comprised of anolyte compartment 42 as anolyte.Thus, especially can be to the single reaction parameter in cathode compartment 42, for example pressure and flow velocity are made suitable impact, and it is few especially to remain under this applicable cases the amount of the catholyte that produces as " waste product ".
For the material property of monitoring prepared anolyte and in order to measure, pipeline 24 is flowed out in the sensor of certain number (especially flow sensor (Mengensensor) 66, temperature sensor 68, pH sensor 70 and the sensor 72 that is used for measuring redox-potential) access.
Such as already mentioned, for the anolyte of special high-quality is provided, with reference to the accompanying drawings device 1 is designed to anolyte compartment 42 is connecting before and after each other aspect the medium flow with the serial connection form, cathode compartment 44 is in parallel aspect medium flow simultaneously.In its chemical characteristics, especially the ratio of reactive chlorine and redox-potential, and aspect anti-storage the solution running gear 1 and obtaining in the following way of the electrochemical activation of special high-quality: via inflow line 4 brackish water is fed in the cathode compartment 44 with parallel way by bifurcation point 48.At this, make the suitable valve 22 of the concentration of described salt solution in softening water and/or Venturi 8 and (say more definitely according to salts contg desired in the finished product, ionic concn) regulates, and in electrolytic module, carry positively charged ion electrolysis liquid with the flow velocity of suitable selection.After the retention period, catholyte is loaded by film adjacent in every kind of situation 46 usefulness ions in cathode compartment 44, wherein between each anode and each negative electrode, apply electrolysis voltage.
Subsequently, again point 54 is exported and be transported to catholyte from cathode compartment 44.At point 54 catholyte is divided into two shuntings, the total flux of wherein said catholyte about 50 to 95%, the first shunting of about 90% of preferred total flux is transported in the anolyte compartment 42 of the first electrolyzer 40 that the flow direction at anolyte arranges by connecting pipeline 58.On the contrary, the second shunting of catholyte (be equivalent to the about 5 to 50% of total flux, preferably 10% of about total flux) is transported to collection container 64 by vent line 60.
Subsequently, the anolyte compartment 42 of the first electrolyzer 40 that arranges from the flow direction at anolyte, make described the first shunting as anolyte with series system by experiencing a plurality of each other continuous electrochemical activation steps in the mode of multiple-stage treatment in the anolyte compartment 42 of the electrolyzer 40 of serial connection aspect the medium and in this process.
The feature of the solution of the electrochemical activation that obtains in this mode especially is to have the reactive chlorine of relative high-content in the situation of high-storage stability.At this, the salts contg in the final product (namely in prepared anolyte and in prepared catholyte) can be adjusted corresponding add-on by the current that salt solution fed softening water from saline container 10 time and regulate in a usual manner (for example optionally be adjusted to " lower concentration " or also be adjusted to " high density ").Especially can be by salt solution being blended into the specific conductivity of suitably presetting the finished product in the current; At this, can be with conductivity adjustment to about 10mS/cm for the relatively low anolyte of active chlorine concentrations, and can be with conductivity adjustment to 18mS/cm for the relatively high anolyte of active chlorine concentrations.
Subsequently, can suitably regulate on the one hand anolyte and on the other hand " the processing time length " of catholyte, the pH value that especially can regulate targetedly thus the finished product by the flow rate of (namely in electrolytic module 2) medium in the conditioned reaction device suitably.At this, the operating temperature in the medium flow (it depends on the strength of current of electrolysis stream) can not be selected too highly, in order to guarantee high quality product.At this, not only for the anolyte of lower concentration but also for the anolyte of high density, the pH value can preferably be regulated in 7.0 to 7.6 scope, the anolyte that wherein produces can be the colourless liquid of clarification, and it has smell and for example 850 to 950mV redox-potential (potentiometer measurement) that chlorine produces.But also preferably be adjusted to above 1500mV, especially also have the redox-potential that surpasses 2000mV.
