Abstract
Description
Spôsoby elektrolytického spracovania odpadových vôd v takzvaných rúrkových reaktoroch sú všeobecne známe. Pracujú s nízkonapäťovým jednosmerným prúdom, pričom elektródy buď zostávajú v pôvodnom stave alebo sa elektrolýzou rozpúšťajú. Ako elektródy sa stali známymi medzi iným železo a hliník. Konštrukcia známych rúrkových reaktorov Je obvykle taká, že ako obalová rúrka sa používa rúrka z umelej hmoty s izolačnými vlastnosťami, napr. z polypropylénu. Do tejto obalovej rúrky sa vkladá napr. oceľová alebo hliníková rúrka, ktorá sa tesne dotýka rúrky z umelej hmoty. Zhora sa do vnútornej rúrky zavedie ďalšia oceľová alebo hliníková rúrka. Prstencový priestor medzi obidvoma rúrkami, z ktorých Jedna je zapojená ako katóda a druhá ako anóda. Je reakčným priestorom pre elektrolytickú úpravu pretekajúcej odpadovej vody. .......Methods of electrolytic treatment of waste water in so-called tubular reactors are generally known. They operate at low voltage direct current, whereby the electrodes either remain in their original state or dissolve by electrolysis. Iron and aluminum have become known as electrodes among others. The construction of known tubular reactors It is usually such that a plastic tube with insulating properties, e.g. made of polypropylene. Into this packaging tube is inserted e.g. a steel or aluminum pipe that closely touches the plastic pipe. An additional steel or aluminum tube is introduced from above into the inner tube. An annular space between the two tubes, one of which is connected as a cathode and the other as an anode. It is a reaction area for the electrolytic treatment of flowing wastewater. .......
Nedostatkom týchto rúrkových reaktorov je ich silne obmedzená použiteľnosť v prípadoch, kedy sa čistia odpadové vody. ktoré ma jú sklon v priebehu elektrolytické i elektródach usadeniny. K týmto odpadovým iným vody obsahujúce tenzidv. emulzie lakov.A disadvantage of these tubular reactors is their severely limited applicability in wastewater treatment plants. which have a tendency during electrolytic and electrode deposits. To these other waste water containing surfactants. emulsions of lacquers.

Vynález si kladie za úlohu používať rúrkový reaktor horeuvedenóho druhu tiež pri tých odpadových vodách, ktoré pri elektrolytickom spracovaní, prejavujú sklon k vyzrážaniu usadenín. Táto úloha je pri zariadení, ktoré bolo uvedené úvodom, vyriešená podľa vynálezu tým. že katóda a anóda sú zapojené tak. aby sa dali prepólovať. pričom sa využíva poznatok, že sa usadeniny na elektródach rúrkových reaktorov v prípade navrhovaného prepólovania elektród opáť uvoľnia a že sa môžu spoločne s upravovanou odpadovou vodou odviesť do vločkovacej nádrže, ktorá je zaradená ďalej.SUMMARY OF THE INVENTION It is an object of the present invention to use a tubular reactor of the aforementioned type also in those effluents which, in electrolytic treatment, tend to precipitate deposits. This object is solved by the invention according to the invention in the device mentioned at the outset. that the cathode and the anode are so connected. so that they can be reversed. utilizing the fact that deposits on the electrodes of the tubular reactors are released again in the case of the proposed polarity reversal of the electrodes and that, together with the treated waste water, they can be discharged to a flocculation tank which is included below.
Podstata vynálezuSUMMARY OF THE INVENTION
Uvedené problémy s čistením a úpravou odpadových vôd elektrolýzou sa vyriešia zariadením. ktoré pozostáva z najmenej dvoch súosovo umiestnených rúrok zo železa a/alebo hliníka so súosovo umiestneným hrdlom, pričom jedna rúrka ...je zapojenú ako katóda, druhá potom ako anóda a pritom prstencový priestor medzi obidvoma rúrkami, slúži ako reakčný priestor pre pretekajúcu odpadovú vodu a podstata vynálezu spočíva v tom, že v zariadení anóda i katóda sú zapojené s možnosťou ich prepólovanía: časový interval, prepólovanía anódy a katódy sa nastavuje v závislosti od druhu práve upravovanej odpadovej vody:The above problems with wastewater treatment and treatment by electrolysis will be solved by the plant. which consists of at least two coaxially arranged iron and / or aluminum tubes with a coaxial throat, one tube ... being connected as a cathode, the other anode and the annular space between the two tubes serving as a reaction space for the waste water flowing through and the principle of the invention is that both the anode and the cathode are connected with the possibility of their polarity reversal: the time interval, the polarity of the anode and the cathode is set according to the type of waste water being treated:
anódy a katódy je elektrického odporu medzi rade a všetky reaktory stá č a s o v ý i. n t er v a 1. p r e p ó 1 o v a n i. a regulovateľný v závislosti od nimi:anode and cathode is the electrical resistance between the series and all reactors of the rack. n t er v a 1. p r e p o 1 o v a n i. and controllable accordingly:
je umiestnených viac reaktorov v elektricky zapojené s možnosťou súčasného prepólovanía:more reactors are placed in electrically connected with possibility of simultaneous polarity reversal:
...je umiestnených viac súosových reaktorov v rade a každý z nich je možné individuálne prepólovať.... there are several coaxial reactors in line and each of them can be reversed individually.
Pri odpadových vodách. ktorých zloženie a tým i ich sklon k vytváraniu usadenín sú známe, môže byť časový interval medzi jednotlivými prepólovaniami nastavený vopred a to konštantné v závislosti od príslušného druhu odpadovej vody.For waste water. whose composition and thus their tendency to build up deposits are known, the time interval between the polarity reversals can be set beforehand, depending on the respective waste water type.
Podlá vynálezu .je však tiež samozrejme možné nastaviť, príp. r i a d i ť č a s o v ý in t e r v a 1 ...j e d n o 11 i v ý c h p r e p «51 o v a t, í. v-~ z á y i-s 1 o s t i od príslušnélio stavu nabitia elektród. to' ^W^ťfenä v závislosti od elektrického odporu medzi obidvoma elektródami.However, according to the invention, it is of course also possible to adjust or adjust. d i n i n i n i n i n i n i n i n i n i n i n i n i n i n i n i n i n i n i n i n i n i n i n i n i n i n i n i n i n i n i n i n i n i n i n i n i n i n i n i n i n i n i n i n i n i n i n i. the electrode charge state. This depends on the electrical resistance between the two electrodes.
Pri väčšíoh zariadeniach. v ktorých je umiestnených viac súosových rúrkových reaktorov v rade. sa javí. hlavne v súvislosti s úpravou známych druhov odpadových vôd ako zvlášť jednoduché a účelné zaistiť možnosť súčasného prepólovanía všetkých reaktorov. takže potom je možné prostredníctvom jediného riadenia spínať všetky reaktory naraz.For larger devices. in which several coaxial tubular reactors are located in a row. appears. especially in connection with the treatment of known types of waste water, it is particularly simple and expedient to ensure the possibility of simultaneous polarity of all reactors. so all the reactors can be switched at once with a single control.
Podľa druhu spracovávanej odpadovej vody sa však môže pri radovom usporiadaní, niekoľkých reaktorov javiť ako účelné navrhnúť také riadenie, ktoré umožní oddelené prepólovanie jednotlivých rúrkových reaktorov. ý tomto prípade môžu byť silnejšie zaťažované reaktory prepólovávané častejšie než reaktory zaťažené menej.Depending on the type of waste water to be treated, however, in a series arrangement of several reactors, it may prove expedient to design a control system which permits separate polarity of the individual tubular reactors. In this case, heavily loaded reactors can be reversed more frequently than reactors loaded less.
