Description

Filteranordnung zur Rohwasserreinigung für Verdampfer u. dgl. mit Koksfüllung.Filter arrangement for raw water purification for evaporators and the like with Coke filling.

Bei Rohwasserreinigern für Verdampfer wird das vorgewärmte Rohwasser durch einen Filter geleitet, welcher mit Koks gefüllt ist Es hat sich nun gezeigt, daß ein solcher Koksfilter in manchen Fällen trotz verhältnismäßig langer Kokssäule nicht genügt, um den ausgefällten Kalkschlamm möglichst restlos abzufiltern. In the case of raw water purifiers for evaporators, the preheated raw water passed through a filter which is filled with coke It has now been shown that such a coke filter in some cases despite a relatively long coke column not enough to filter off the precipitated lime sludge as completely as possible.

Es ist dies wohl darauf zurüclçzuführen, daß die Oberfläche der Koksstücke, welche die Filtermasse bilden, rauh, porös und zackig ist, so daß sich auf dieser Oberfläche ein feiner Schlammüberzug nicht bilden kann, wie dies z.B. auf den einzelnen Stücken eines Kiesfllters der Fall ist. Nun hat es sich gerade herausgestellt, daß auf dieser feinen Schlammschicht die eigentliche Filterwirkung beruht. This is probably due to the fact that the surface of the coke pieces, which form the filter mass, is rough, porous and jagged, so that on this Surface a fine sludge coating cannot form, as e.g. on the individual Pieces of a gravel filter is the case. Well it just turned out that the actual filter effect is based on this fine layer of sludge.

Andererseits empfiehlt es sich, wegen der sonstigen guten Filtereigenschaften des Koks, insbesondere wegen seines geringen Gewichtes, die Koksfüllung beizubehalten.On the other hand, it is recommended because of the other good filter properties of the coke, in particular because of its low weight, to maintain the coke filling.

Erfindungsgemäß wird nun die Wirksamkeit einer Filteranordnung bei Rohwasserreinigern für Verdampfer u. dgl. dadurch wesentlich erhöht, daß bei einem mit Koks als Filtermasse arbeitenden Filter in den Lauf des zu reinigenden Wassers gleichzeitig eine Filtersäule mit kleinen Filterstücken von glatter und abgerundeter Oberfläche, z.B. I (; es, eingeschaltet ist. According to the invention, the effectiveness of a filter arrangement is now at Raw water purifiers for evaporators and the like are therefore essential elevated, that in the case of a filter working with coke as the filter material, in the course of the filter to be cleaned Water at the same time a filter column with small filter pieces of smooth and rounded surface, e.g. I (; it, is switched on.

Die Erfindung ist beispielsweise in der Zeichnung veranschaulichit, und es stellt dar: Abb. I einen Längsschnitt durch einen Filter nach der Erfindung, Abb. 2 eine Seitenansicht -desselben teilweise geschnitten (Ansicht senkrecht zu der Schnittebene nach Abb. 1). The invention is illustrated for example in the drawing, and it shows: Fig. I a longitudinal section through a filter according to the invention, Fig. 2 is a side view of the same partially cut (view perpendicular to the section plane according to Fig. 1).

In einem Behälter I ist in bekannter Weise eine Koksfiltermasse 2 eingelagert. Zum Eintritt für das von einem Rohwasserreiniger kommende Wasser sind Öffnungen 3 vorgesehen. Erfindungsgemäß ist nun in den Weg des zu reinigenden Wassers eine Filtersäulje mit kleinen Filterkörpern glatter und abgerundeter Oberfläche eingeschaltet. Bei dem gezeichneten Ausführungsbeispiel geschieht dies dadurch, daß im Oberteil des Filterbehälters I ein Einsatz 4 mit Siebboden 5 angeordnet ist, welcher mit solchen Filterstücken 6, z. 3. In a container I is a coke filter mass 2 in a known manner stored. To the inlet for the water coming from a raw water purifier are Openings 3 are provided. According to the invention is now in the way of the water to be purified a filter column with small filter bodies with a smooth and rounded surface switched on. In the illustrated embodiment, this is done by that in the upper part of the filter container I an insert 4 with a sieve bottom 5 is arranged, which with such filter pieces 6, z. 3.

Kies, gefüllt ist. Während die Koksmasse nach Öffnen einer Klappe 7 nach unten entleert werden kann, ist der Einsatz 4 nach Abnahme eines Deckels 8 auf dem Behälter 1 nach oben herausnehmbar, wozu besondere Handhaben g vorgesehen sind. Das durch die Öffnungen 3 eintretende vorgewärmte Rohwasser durchströmt die Filtermasse in dem Einsatz 4 und sodann die KoksfiItermasse, um durch Stutzen lo einer entsprechenden Pumpe zuzufließen. Das Wasser wird in der Filtermasse des Einsatzes 4 bereits intensiv gereinigt. Schlammteilchen, welche aus dieser Filtermasse beim weiteren Durchfluß des Wassers durch den Filter mitgerissen werden sollten, werden sicher in der Koksfiltermasse zurückgehalten.Gravel that is filled. While the coke mass after opening a flap 7 can be emptied downwards, the insert 4 is after removing a lid 8 on the container 1 can be removed upwards, for which purpose special handles g are provided are. The preheated raw water entering through the openings 3 flows through the Filter mass in the insert 4 and then the coke filter mass to lo to flow to an appropriate pump. The water is in the filter mass of the insert 4 already intensively cleaned. Sludge particles, which from this filter mass when further flow of water through the filter should be entrained safely retained in the coke filter mass.
