Abstract

The filter is for the treatment of liqs. with mechanical, ionic and/or non-ionic impurities, using floating filter material and cation/anion exchangers and/or absorbent resins. The material, exchangers and/or resins after collecting the impurities are cleaned or generated by a current in the opposite direction. In the free filter chamber there are two or more floors with nozzles above a perforated floor. The space between the nozzle floors is filled with ion exchangers or absorbent resin, and that between the lower nozzle floor and the perforated one with floating filter material.

Description

  

  
 



   Die vorliegende Erfindung betrifft ein Filter zum Ausscheiden von mechanischfesten und gelösten Verunreinigungen aus Flüssigkeiten, mit einem geschlossenen, mit Eingangsöffnung und Ausgangsöffnung versehenen Filtergehäuse.



   Flüssigkeiten, die mit mechanischfesten und gelösten Verunreinigungen beladen sind, wurden bisher so behandelt, dass jeweils ein Filter zum Entfernen von mechanischfesten Verunreinigungen und mindestens ein weiteres Filter zum Entfernen von gelösten ionalen und/oder nichtionalen Verunreinigungen verwendet wurden.



   Der Nachteil dieser bekannten Verfahrenstechnik besteht darin, dass ein beachtlicher konstruktiver Aufwand notwendig ist, um die Behandlung durchzuführen. Hinzu kommt noch der Nachteil, dass je nach Art der vorliegenden Verunreinigungen die entsprechenden Behandlungsflüssigkeiten vorliegen müssen. Die Erfindung bezweckt ein Filter zum Ausscheiden von mechanischfesten und gelösten Verunreinigungen aus Flüssigkeiten zu schaffen, mit dem es möglich ist, den gesamten Behandlungsprozess in einem Filtergehäuse ablaufen zu lassen.



   Das erfindungsgemässe Filter ist dadurch gekennzeichnet, dass im Filterraum ein Lochboden und oberhalb desselben mindestens zwei Düsenböden vorgesehen sind, dass der zwischen dem Lochboden und dem nächsten Düsenboden befindliche Raum mit einem schwimmfähigen Filtermaterial aufgefüllt ist, welches zur Entfernung der mechanischfesten Verunreinigungen dient, und dass der zwischen den Düsenböden befindliche Raum ein Ionenaustauscher- oder Adsorbermaterial oder beide Materialien aufweist zur Entfernung der gelösten Verunreinigungen.



   Nachfolgend wird anhand der Zeichnung ein Ausführungsbeispiel des erfindungsgemässen Filters beschrieben.



   Das Filtergehäuse besteht aus einem zylindrischen Behälter 1, der an einem Ende mit einem gewölbten Boden 2 mit Eingangsöffnung und am anderen Ende mit einem Deckel 3 mit Ausgangsöffnung versehen ist. Im Filterraum 4 sind im unteren Bereich ein Lochboden 5 und im übrigen Bereich mindestens zwei Düsenböden 6, 7 angeordnet. Zwischen dem Lochboden 5 und dem Düsenboden 6 befindet sich ein aus schwimmfähigem Filtermaterial 8 bestehendes Bett, welches zur Entfernung der mechanischen Verunreinigungen dient.



  Zwischen dem Düsenboden 6 und dem Düsenboden 7 liegt ein aus Kationen- oder Anionenaustauschern oder Adsorberharzen bestehendes Filterbett 9, mit dem die ionalen bzw. nichtionalen Verunreinigungen entfernt werden. An Stelle des einzigen Bettes können auch mehrere Betten aus Kationen- oder Anionenaustauscher und/oder Adsorberharzen im Filtergehäuse angeordnet sein. Die Trennung der einzelnen Betten erfolgt dann jeweils durch Düsenböden. Es sei darauf hingewiesen, dass die Reinigung der einzelnen Filterbetten im Gegenstrom erfolgt.



   Der Vorteil, der mit dem beschriebenen Filter erreicht wird, besteht darin, dass mit der unteren Filterschicht, die aus schwimmfähigem Filtermaterial besteht, die mechanische Reinigung vorgenommen wird und im Anschluss daran durch das über dem aus schwimmfähigem Filtermaterial durch den Düsenboden getrennt angeordnete Filterbett die ionalen bzw.



  nichtionalen Verunreinigungen entfernt werden. Durch die Vereinigung der verschiedenen Behandlungsphasen in einem Filter wird der konstruktive Aufwand wesentlich reduziert.



  Auch ist die Reinigung des mit den mechanischen Verunreinigungen beladenen schwimmfähigen Filtermaterials kostenmässig äusserst günstig, da zu dessen Reinigung die Reinigungsflüssigkeit der für die Austauscherharze bzw. Adsorberharze bereits verwendeten Flüssigkeit benutzt wird. 



  
 



   The present invention relates to a filter for separating mechanically solid and dissolved impurities from liquids, with a closed filter housing provided with an inlet opening and an outlet opening.



   Liquids that are loaded with mechanically solid and dissolved impurities have so far been treated in such a way that in each case a filter was used to remove mechanically solid impurities and at least one additional filter was used to remove dissolved ionic and / or non-ionic impurities.



   The disadvantage of this known process technology is that a considerable design effort is necessary to carry out the treatment. There is also the disadvantage that, depending on the type of impurities present, the corresponding treatment liquids must be present. The invention aims to create a filter for separating mechanically solid and dissolved impurities from liquids, with which it is possible to allow the entire treatment process to take place in one filter housing.



   The filter according to the invention is characterized in that a perforated base is provided in the filter space and at least two nozzle bases are provided above it, that the space between the perforated base and the next nozzle base is filled with a floatable filter material which serves to remove the mechanically solid impurities, and that the The space between the nozzle bottoms has an ion exchange or adsorber material or both materials to remove the dissolved impurities.



   An exemplary embodiment of the filter according to the invention is described below with reference to the drawing.



   The filter housing consists of a cylindrical container 1 which is provided at one end with a curved base 2 with an inlet opening and at the other end with a cover 3 with an outlet opening. In the filter space 4, a perforated plate 5 is arranged in the lower area and at least two nozzle plates 6, 7 are arranged in the remaining area. Between the perforated base 5 and the nozzle base 6 there is a bed made of floatable filter material 8, which is used to remove mechanical impurities.



  Between the nozzle base 6 and the nozzle base 7 there is a filter bed 9 consisting of cation or anion exchangers or adsorber resins, with which the ionic or non-ionic impurities are removed. Instead of the single bed, several beds made of cation or anion exchangers and / or adsorber resins can also be arranged in the filter housing. The individual beds are then separated by nozzle plates. It should be noted that the cleaning of the individual filter beds takes place in countercurrent.



   The advantage that is achieved with the filter described is that the mechanical cleaning is carried out with the lower filter layer, which consists of buoyant filter material, and then the ionic cleaning is carried out by the filter bed, which is separated from the buoyant filter material by the nozzle base or.



  non-ionic impurities are removed. By combining the various treatment phases in one filter, the design effort is significantly reduced.



  The cleaning of the buoyant filter material loaded with the mechanical impurities is also extremely favorable in terms of cost, since the cleaning liquid of the liquid already used for the exchange resins or adsorber resins is used for its cleaning.
