Abstract
Description
Gegenstand der Erfindung ist ein Filter für die Filtration von partikulären Schad- oder Feststoffen aus Flüssigkeiten und Gasen gemäss Patentanspruch 1.object The invention is a filter for the Filtration of particulate Harmful or solids from liquids and gases according to Claim 1.
Strassenbaustellen-, Bergbau- und Industrieabwässer sind mit Feststoffen, wie Beton- oder Gesteinsabrieb, sowie mit kleinen und grösseren Steinen und/oder mit gelösten Schadstoffen belastet. Die ungleiche Korngrösse der Feststoffe sowie deren prozentuale Aufteilung oder die gelösten Stoffe verlangen bei der Reinigung unterschiedliche Reinigungsverfahren. Grössere Feststoffe, wie Kies und Steine, mit einer spezifischen Dichte, die grösser ist als diejenige des Wassers, können verhältnismässig einfach durch Gravitation/Sedimentation auch in bewegtem Wasser ausgeschieden werden. Feinere und Feinststoffe oder gelöste Schadstoffe verlangen einen höheren Aufwand. Da alle Stoffe gleichzeitig anfallen, muss eine Vorrichtung zur Reinigung von Baustellen und Bergbauabwässern mit unterschiedlichen physikalischen Trennmethoden arbeiten. Nebst den genannten Stoffen können solche Abwässer auch mit aufschwimmbaren Stoffen wie Holzteilen, Kunststoffteilen etc. befrachtet sein, welche eine komplett unterschiedliche Trennmethode verlangen. Nebst den suspendierten Stoffen können auch emulgierende Stoffe wie Öle, Fette sowie wasserlösliche Stoffe im Abwasser vorhanden sein.Strassenbaustellen-, Mining and industrial wastewater are with solids, such as concrete or rock abrasion, as well as with small and larger stones and / or with dissolved Contaminated pollutants. The uneven grain size of the solids as well as their percentage Division or the dissolved Substances require different cleaning methods when cleaning. bigger Solids, such as gravel and stones, with a specific density, the bigger ones is as the one of the water, can relatively easy excreted by gravity / sedimentation in moving water become. Finer and finer substances or dissolved pollutants require one higher Effort. Since all substances occur at the same time, a device must for the cleaning of construction sites and mining wastewater with different physical Separation methods work. In addition to the substances mentioned, such sewerage also with floating materials such as wooden parts, plastic parts etc., which is a completely different separation method desire. In addition to the suspended substances can also emulsifying substances like oils, Fats and water-soluble Substances may be present in the wastewater.
Es ist bekannt, dass Baustellenabwasser, das stark mit partikulären Stoffen beladen ist, wenn zum Beispiel Betonoberflächen mit Hoch- oder Höchstdruck gereinigt werden oder wenn gebohrt oder mit Trennscheiben gefräst und Steinoberflächen abgeschliffen werden, nicht einem Gewässer oder einer Kanalisation zugeführt werden darf. Auch Abwässer mit viel Schluff und Ton aus Aushubwaschanlagen oder Betonitschlämme zur Grubenabdichtung dürfen nicht direkt abgeführt werden.It It is known that construction site wastewater that is highly particulate matter For example, concrete surfaces with high or high pressure are loaded be cleaned or if drilled or milled with cutting discs and sanded stone surfaces not a body of water or a sewer may be. Also wastewater with a lot of silt and clay from excavated or Betonitschlämme to Pit sealing may not directly discharged become.
Mit den bekannten Vorrichtungen werden meist nur einzelne Fraktionen sicher aus dem verschmutzten Abwasser entfernt, wobei insbesondere die Feinstanteile und gelöste Stoffe zurückbleiben. Werden gravitativ arbeitende Behandlungsanlagen oder Filter eingesetzt, mit denen auch Feinstanteile ausfiltrierbar sind, so neigen diese zu rascher Verstopfung, welche eine Rückspülung oder einen Austausch der Filterelemente verlangt, oder es müssen zusätzlich Absetzanlagen für Feinstoffe eingesetzt werden, welche viel Raum benötigen.With the known devices are usually only individual fractions safely removed from the polluted wastewater, in particular the Very fine and dissolved Remain behind. Become used gravitational treatment plants or filters, with which very fine particles are filtered out, so they tend too rapid obstruction, which a backwashing or replacement of Requires filter elements, or it must also additional settling systems for fines be used, which need a lot of space.
Eine Aufgabe der vorliegenden Erfindung ist die Schaffung eines Filters zur Reinigung von partikulär stark mit Grob- und mit Feinstoffen verschmutztem Abwasser, insbesondere für die Verwendung auf Baustellen, im Bergbau oder in der Industrie, welche in einer kompakten, leicht transportierbaren, d. h. auf Baustellen mit geringem Platzangebot aufgestellt und betrieben werden kann.A The object of the present invention is to provide a filter for cleaning of particulate strong with coarse and Wastewater contaminated with fines, in particular for use on construction sites, in mining or in industry, which in one compact, easily transportable, d. H. on construction sites with low Space can be set up and operated.
Gelöst werden diese Aufgaben durch einen Filter gemäss Patentanspruch 1.Be solved These objects by a filter according to claim 1.
Es gelingt mit dem erfindungsgemässen Filter auf kleinstem Raum in einem transportierbaren Behälter mit einer Zuleitung für das verunreinigte Abwasser und einer Ableitung des gereinigten Abwassers unterzubringen. Durch den Einsatz der Querstromfiltration (Cross-Flow) können Feinststoffe ausgefiltert werden, ohne dass eine Verstopfung der Filter eintritt bzw. eine Rückspülung des Filters in kurzen Abständen notwendig wird. Dadurch kann die Anlage drucklos und selbstregulierend betrieben werden.It succeeds with the inventive Filter in a small space in a transportable container with a supply line for the contaminated wastewater and a discharge of the purified wastewater accommodate. Through the use of cross-flow filtration (cross-flow) can Fine substances are filtered out without causing blockage Filter enters or a backwash the Filters in short intervals becomes necessary. This allows the system to be depressurized and self-regulating operate.
