Description

Zywice zuzy¬ te sa fhiidyzowane czescia dostarczonej wody su¬ rowej dostosowanej do wartosci dla przeplywo¬ mierza D4 zaworem regulacyjny 65. Zywica oraz zanieczyszczenia zostaja uniesione przewodem 51 60 poprzez zawór ograniczajacy przeplyw 52 do se- peratorów D\ Wydajnosc unoszenia regulowana jest do wartosci dla przeplywomierza D5 wyzszej ód wartosci dla przeplywomierza D4 plywakiem 66 podlaczonym do przewodu wylotowego 67 po- 65 8 laczonego z kompensacja rurowa pólkolista regu¬ lowana w wysokosci. To natezenie dla przeply¬ womierza D5 'unosi zanieczyszczenia trwale pod¬ czas, gdy zywice oczyszczone opadaja na dno se¬ paratora D\ Caly przeplyw przez przeplywomierz D5 jest wyrzucany do scieku lub ewentualnie kierowany do zbiornika zasilajacego G po uprzednim prze- filtrowaniu. Gdy tylko proces unoszenia prawie sie konczy, zawór 64 zamyka sie, a zywica znaj¬ dujaca sie jeszcze w górnej czesci zaworu 52 klaruje sie i przechodzi przez niego tak samo jak przy nastepnym przemieszczaniu, gdy sepa¬ rator D' poddany jest cisnieniu, to zawór 52 wy¬ pelniony czysta woda zamyka sie. Zbiornik E opróznia sie automatycznie syfonowo po kazdym przemieszczeniu zywicy, natomiast woda surowa odzyskana, jest kierowana do zbiornika G.Fig. 3 pokazuje w szczególach naczynie myjace fluidalne, które moze równiez korzystnie miec ksztalt naczynia przedstawionego na fig. 1.Na fig. 3 naczynie do mycia D przez fluidy- zacje jest w ksztalcie cylindryczno-stozkowym w czesci dolnej. Sluzy jednoczesnie do fluidyzacji oraz do magazynowania ladunku przeplukanej zy¬ wicy, przed jej powtórnym wprowadzeniem do kolumny wskutek kolejnej fazy przemieszczenia sie zloza zywicy.Przewód wlotowy zywicy zuzytej wprowadzony jest osiowo w czesci górnej do naczynia D. Prze¬ wód ten jest wspólosiowy i pionowy oraz prze¬ dluzony jest do pewnej wysokosci naczynia w tym przypadku do 2/3 naczynia. Przewód ten zaopatrzony jest w swojej dolnej czesci w dy- fuzor 72 zanurzony w zbiorniku stozkowym 73 w jego osi. Przekroje przewodu, dyfuzora i zbior¬ nika rozszerzaja sie. Krawedz górna zbiornika stanowi obwodowy element przelewowy dla zywi¬ cy. Ponad zbiornikiem znajduje sie wyciag two- rzady komore cylindryczna 74, polaczony zweze¬ niem 75 do przewodu odprowadzajacego 76 ciecz obciazona, przy czym przewód ten usytuowany jest wspólsrodkowo z przewodem 71. Naczynie za¬ wiera prócz tego zawór spustowy 78 w czesci dol¬ nej stozkowej i przewód 79 polaczony stycznie w czesci górnej cylindra.Ilosc zywicy uzytej, obciazonej zanieczyszcze¬ niami wyplywa z ciecza unoszaca przewodem 71.W zbiorniku 73 w nastepstwie róznicy poziomu wejscia i przelewu tworzy sie zloze fluidalne.Granulki czystej zywicy wyplywaja przez obowo- dowy przelew i klaruja sie na dnie naczynia, pod¬ czas gdy zanieczyszczenia unoszone sa przez prad w góre do przewodu wylotowego 76 zaopatrzo¬ nego, w automatyczny zawór 80. Wskutek ustania fluidyzacji zawór 80 zamyka sie, a zanieczyszcze¬ nia sa zgeszczone w dyfuzorze 75 lub w przewo¬ dzie 76 klarujac sie i opadajac do zbiornika i zo¬ staja calkowicie przejete przy nastepnej fluidyza¬ cji. Z chwila wypróznienia naczynia, zawór 80 jest zamkniety, natomiast zawór 78 otwiera sie i w tym pewna objetosc cieczy surowej przenika do na¬ czynia przewodem 79. Jednoczesnie wokól komo¬ ry 74 powstaje wyplyw wirowy (spiralny), który zapewnia calkowity wyplyw sklarowanej zywicy do czesci stozkowej naczynia powyzej zaworu 78.9 Pozostajaca ewentualnie brudna ciecz w komorze 74 nie miesza sie z ciecza surowa, co zabezpiecza przed powrotem zanieczyszczen do czystej zywicy.Ewentualnie, dla uregulowania klarowania sie czystej zywicy mozna przewód 76 zaopatrzyc w 5 male otworki 81, przez które woda przemieszcza¬ na przy klarowaniu sie czystej zywicy zostaje zassana i przez przeplyw zasadniczy splywa do przewodu 76. 10 PLThe spent resins are phiidized with a portion of the raw water supplied adjusted to the value for the flow meter D4 by a control valve 65. The resin and contaminants are lifted through line 51 60 through the flow restrictor valve 52 to the seals. The lifting capacity is adjusted to the value for the flow meter D5 has a higher value for the flow meter D4 with a float 66 connected to the outlet line 67 connected to a height adjustable semicircular tube compensation. This intensity for the flow meter D5 'lifts the contaminants permanently while the cleaned resins sink to the bottom of the separator D. The entire flow through the flow meter D5 is thrown into the drain or possibly directed to the feed tank G after being filtered. As soon as the lifting process is almost complete, the valve 64 closes and the resin still on top of the valve 52 clears and passes through it, just as it does in the next movement, when the separator D 'is under pressure, the valve 52 full of pure water is closed. The E tank is emptied automatically by siphon after each resin displacement, while the recovered raw water is directed to the G. Fig. 3 shows in particular a fluidized washing vessel, which may also preferably have the shape of the vessel shown in FIG. 1. In FIG. 3, the washing vessel D by fluidization is in the cylindrical-conical shape at the bottom. It is used simultaneously for fluidization and for storing the charge of rinsed resin before it is reintroduced into the column due to the next phase of resin bed displacement. The spent resin inlet line is axially inserted in the upper part into the vessel D. This line is coaxial and vertical, and it is extended to a certain height of the vessel, in this case up to 2/3 of the vessel. This conduit is provided in its lower part with a diffuser 72 which is immersed in a conical tank 73 along its axis. The cross-sections of the conduit, diffuser and reservoir widen. The top edge of the tank is a peripheral overflow for the resin. Above the tank there is a tubular chamber 74 connected by a stub pipe 75 to a drainage pipe 76 of the loaded liquid, the pipe being located concentrically with the pipe 71. The vessel also includes a drain valve 78 in the lower conical part. and a conduit 79 connected tangentially in the upper part of the cylinder. The amount of used resin, laden with contaminants, flows out of the lifting liquid through conduit 71. In tank 73, the difference between the inlet and the overflow level forms a fluidized bed. The granules of pure resin flow through the circumferential overflow and they clear at the bottom of the vessel, while the debris is lifted upward by the current into the outlet conduit 76 provided with an automatic valve 80. Due to the cessation of fluidization, the valve 80 closes and debris is trapped in the diffuser 75 or in the conveyor. The day 76 will clear and fall into the reservoir and are fully absorbed at the next fluidization. As soon as the vessel is emptied, the valve 80 is closed and the valve 78 opens, and in this a certain volume of raw liquid penetrates into the vessel through the conduit 79. At the same time, a vortex (spiral) flow is created around the chamber 74, which ensures the complete discharge of the clarified resin into the part. the conical vessel above the valve 78.9 Any dirty liquid remaining in the chamber 74 does not mix with the raw liquid, which prevents the contamination from returning to the clean resin. Alternatively, to regulate the clearing of the pure resin, the line 76 can be provided with 5 small holes 81 through which the water moves ¬ when clearing the pure resin, it is sucked in and flows through the main flow to the line 76. 10 EN
