Przedmiotem wynalazku jest elektrolizer do na¬ powietrzania scieków i wody przed jej uzdatnia¬ niem na odzelaziaczach.Znane sa urzadzenia do 'napowietrzania wody i scieków zbudowane na bazie sprezarki tloczacej powietrze do zbiornika z woda lub sciekami.Znane sa takze urzadzenia w .postaci strumiennic doprowadzajacych swieza natleniona wode do zbiornika.Wada znanych urzadzen jest koniecznosc budo- dania skomplikowanych i drogich urzadzen do na¬ powietrzania zuzywajacych duza ilosc energii. Urza¬ dzenia te charakteryzuja sie halasliwa praca i sklonnoscia do wibracji. Urzadzenia strumieniowe wymagaja specjalnej regulacji przeplywu wody w celu zabezpieczenia przed zalewaniem pomie¬ szczen przez wode wydostajaca sie z przewodu inzektowego zasysajacego powietrze.Elektrolizer wedlug wynalazku zbudowany jest z dwóch zbiorników, ze zbiornika wody wmieszanej korzystnie z kwasem siarkowym i zbiornika z elek¬ trodami. Zbiorniki te polaczone sa szczelina umie¬ szczona w poblizu dna, tworzac maozynie polaczone.Elektrody skladaja sie z anody i kilku ka,todL.

Scianki w dolnej czesci posiadaja otwory laczace poszczególne ko¬ mory. 10 15 20 25 30 W urzadzeniu wedlug wynalazku wykorzystano elektrolityczny rozklad wody na .gazowy tlen i wo¬ dór. Powstajacy tlen doprowadzany jest przewo¬ dem do zbiornika tlenowego skad dalej do mie- szacza zamontowanego przy odzelaziaczu.W wyniku zastosowania elektrolizera wedlug wynalazku uzyskuje sie urzadzenie do napowie¬ trzania wody i scieków proste w budowie i zuzy¬ wajace mala ilosc energii.Napowietrzanie jest skuteczne i zapewnia dopro¬ wadzenie duzej ilosci tleniu pnzy uzdatnianiu wody i scieków. Elektrolizer gwarantuje prace ciagla, bezawaryjna i prosta w eksploatacji.Wynalazek w przykladzie wykonania przedsta¬ wiony zostal na zalaczonym rysunku. Elektrolizer sklada sie ze zbiornika 1 wody zmieszanej z kwa¬ sem siarkowym i zbiornika 2 z elektrodami, ano¬ da 3 i katodami 4. W poblizu dna 5 zbiorników 1 i 2 umieszczona jest szczelina 6, przez co zbiorniki te tworza naczynie polaczone. Zbiornik 1 przy¬ kryty jest pokrywa 7. W zbiorniku 2 znajduja sie scianki 8 dzielace zbiornik na komore tlenowa 9 i wodorowa 10. Komory 9 i 10 polaczone sa otwo¬ rami 11 umieszczonymi w dolnej czesci scianek 8.Elektrody 3 i 4 umieszczone sa w koszulkach 12 w taki sposób, ze powierzchnie czynne elektrod 3 i 4 znajduja sie tylko powyzej otworów 11. Elek¬ trody mocowane sa do dna 5 elektrolizera w oprawkach 13. Do zacisków 14 i 15 elektrod 3 i 4 doprowadzony jest prad elektryczny. Tlen 111 0483 111 048 4 z komory 9 odprowadzany jest przewodem 16 do niepokazanego zbiornika tlenowego. Wodór zas z komory 10 odprowadzany jest przewodem 17 po¬ za pomieszczenie stacji filtrów. Komora tlenowa 9 wyposazona jest w zawór awaryjny 18.W czasie pracy elektrolizera nastepuje elektro¬ lityczny rozklad wody na tlen i wodór. Zapotrze¬ bowanie tlenu dla usuniecia z uzdatnianej cieczy 1 mg zelaza wynosi 0,143 mg. Przyjmujac srednie stezenie zelaza w wodzie w ilosci 1 mg/l, otrzy¬ mujemy zapotrzebowanie tlenu w ilosci 0,286 mg/l.Dla odzelezienia wody w ilosci 1000 nWdobe przy srednim stezeniu zelaza 2 mg/l, otrzymujemy za¬ potrzebowanie teoretyczne 0,283 kg tlenu na dobe.Zuzycie pradu dla wytworzenia tej ilosci tlenu wynosi okolo 2,25 do 3 kWh/dobe. Daje to w po¬ równaniu do systemu strumienicowego i sprezar- 10 15 kowego oszczednosc zuzycia energii elektrycznej okolo 200-krotna.Zastrzezenia patentowe 1.

The disadvantage of the known devices is the need to build complex and expensive energy-consuming aeration devices. These devices are noisy and prone to vibrations. The jet devices require special regulation of the water flow in order to prevent flooding of the rooms by the water coming out of the air-suction injection line. The electrolyser according to the invention consists of two tanks, a water tank mixed preferably with sulfuric acid and a tank with electrodes. These tanks are connected by a slit located near the bottom, forming a connected frame. The electrodes consist of an anode and several channels, todL. They are separated from each other by walls dividing the tank into an oxygen chamber and a hydrogen chamber. Each chamber has a separate outlet for oxygen and one for hydrogen. The lower part walls have openings connecting the individual chambers. In the device according to the invention, the electrolytic decomposition of water into gaseous oxygen and hydrogen is used. The resulting oxygen is led through a conduit to the oxygen tank and then to a mixer mounted at the iron separator. As a result of the use of the electrolyser, according to the invention, a device for aerating water and sewage is obtained that is simple in construction and consumes a small amount of energy. and provides for the introduction of a large amount of smoldering creepers for water and sewage treatment. The electrolyser guarantees continuous, trouble-free and easy-to-use operation. The invention in the embodiment is shown in the attached drawing. The electrolyser consists of a reservoir 1 of water mixed with sulfuric acid and a reservoir 2 with electrodes, anode 3 and cathodes 4. A gap 6 is provided near the bottom 5 of reservoirs 1 and 2, whereby the reservoirs form an interconnecting reservoir. The tank 1 is covered with a lid 7. The tank 2 has walls 8 dividing the tank into an oxygen 9 and a hydrogen chamber 10. The chambers 9 and 10 are connected by openings 11 located in the lower part of the walls 8. Electrodes 3 and 4 are placed in the sleeves 12 in such a way that the active surfaces of the electrodes 3 and 4 are only above the holes 11. The electrodes are fixed to the bottom 5 of the electrolyser in the holders 13. Electric current is supplied to the terminals 14 and 15 of the electrodes 3 and 4. Oxygen 111 0483 111 048 4 from chamber 9 is discharged via line 16 to an oxygen tank, not shown. Hydrogen from chamber 10 is discharged through line 17 outside the filter station room. The oxygen chamber 9 is equipped with an emergency valve 18. During the operation of the electrolyser, the electrolytic decomposition of water into oxygen and hydrogen takes place. The oxygen demand for the removal of 1 mg of iron from the treated liquid is 0.143 mg. Assuming the average concentration of iron in water at 1 mg / l, we obtain oxygen demand of 0.286 mg / l. For water removal of 1000 nWdobe at an average iron concentration of 2 mg / l, we obtain the theoretical need of 0.283 kg of oxygen per The electricity consumption to produce this amount of oxygen is approximately 2.25 to 3 kWh / day. Compared to a jet pump and a compressor system, this results in a savings in electricity consumption of about 200 times. Claims 1.
