Description

Filterfilter

Die Erfindung betrifft ein Filter, das unter Verwendung nachwachsender Rohstoffe, wie Holz oder Einjahrespflanzen, und/oder Recyclingmaterialien, wie Altpapier oder Textilfasern, hergestellt wird.The invention relates to a filter that is manufactured using renewable raw materials, such as wood or annual plants, and/or recycled materials, such as waste paper or textile fibers.

Durchgangsfilter sollen im Regelfall Teilchen unterschiedlicher Dimension aus den das Filter durchströmenden Gasen oder Flüssigkeiten zurückhalten. Die Porengröße der Filter richtet sich dabei nach dem kleinsten zu filternden Teilchen. Enthält die Oberfläche des Filters diese kleinsten Poren, so setzt sie sich u. U. schnell zu. In vielen Fällen werden deshalb mehrere Filter mit abnehmender Porengröße hintereinander geschaltet, wodurch ein erhöhter Herstellungs- und Einbauaufwand entsteht.As a rule, flow-through filters are designed to retain particles of different dimensions from the gases or liquids flowing through the filter. The pore size of the filter is based on the smallest particle to be filtered. If the surface of the filter contains these smallest pores, it can quickly become clogged. In many cases, several filters with decreasing pore sizes are therefore connected in series, which results in increased manufacturing and installation costs.

Aufgabe der Erfindung ist es, ein Filter anzugeben, das billig herstellbar ist und dessen Material später ökologisch unbedenklich entsorgt werden kann.The object of the invention is to provide a filter that can be produced inexpensively and whose material can later be disposed of in an ecologically safe manner.

Erfindungsgemäß wird die Aufgabe mit den in den Ansprüchen genannten und in den Ausführungsbeispielen näher erläuterten Mitteln gelöst.According to the invention, the object is achieved with the means mentioned in the claims and explained in more detail in the embodiments.

Mit Wasserglas gemischte Faserstoffe, Hackgut aus Einjahrespflanzen oder Holzspäne können schichtweise in eine Form gefüllt, gemeinsam verdichtet, ausgehärtet und getrocknet werden. Beginnend mit gröberen Partikeln über mittlere bis hin zu feinen Partikeln kann stufenweise bis quasi kontinuierlich der Porendurmesser der Filterschichten verringert werden, wobei immer nur ein Filterkörper entsteht.Fibres mixed with water glass, wood chips from annual plants or wood chips can be filled into a mould in layers, compacted together, hardened and dried. Starting with coarser particles and moving on to medium and fine particles, the pore diameter of the filter layers can be reduced gradually or almost continuously, whereby only one filter body is created at a time.

Unter Verwendung eines durch die Schichten geleiteten und mit CO2 beladenen Heißgases können auch stärkere Filter relativ schnell durchgehärtet und getrocknet werden.By using a hot gas loaded with CO2 that is passed through the layers, even stronger filters can be hardened and dried relatively quickly.

Das Filtermaterial kann in beliebig geformte FiltereinsätzeThe filter material can be used in any shaped filter inserts

eingebracht und dort ausgehärtet werden, so daß die Herstellung im wesentlichen abfallfrei erfolgt. Auch sind Einbau und Aushärtung in einem fest eingebauten Filtersatz vor Ort möglich.and cured there, so that production is essentially waste-free. Installation and curing in a permanently installed filter set on site is also possible.

Holzpartikel, insbesondere Holzfaserstoffe, haben ein hohes Adsorptionsvermögen gegenüber geruchsbildenden Stoffen. Erfindungsgemäße Filter eignen sich deshalb als Geruchsfilter bzw. als kombinierte Teilchen-/ Geruchsfilter. Durch Erhöhung der adsorptiven Oberfläche, z. B. durch Aktivkohle, kann das Adsorptionsvermögen beträchtlich gesteigert werden. Das aktive Pulver kann in den Filter gesaugt bzw. geblasen werden.Wood particles, especially wood fibers, have a high adsorption capacity for odor-forming substances. Filters according to the invention are therefore suitable as odor filters or as combined particle/odor filters. By increasing the adsorptive surface, e.g. by using activated carbon, the adsorption capacity can be increased considerably. The active powder can be sucked or blown into the filter.

Zur Herstellung können nachwachsende Rohstoffe eingesetzt werden. Die Entsorgung der Filtermaterialien ist, sofern sie beim Filtern nicht durch Schadstoffe kontaminiert wurden, beim Einsatz nachwachsender Rohstoffe problemlos. Werden sie ungeschützt der direkten Bewitterung unter humiden Klimabedingungen ausgesetzt, verrotten die Filtermaterialien vollständig. Das Bindemittel zerfällt allmählich in Pottasche, einem Makronährstoff, und Siliziumdioxid.Renewable raw materials can be used for production. Disposal of the filter materials is easy when renewable raw materials are used, provided they were not contaminated by harmful substances during filtering. If they are exposed to direct weathering in humid climatic conditions without protection, the filter materials will rot completely. The binding agent gradually breaks down into potash, a macronutrient, and silicon dioxide.

Die Erfindung wird nachfolgend an einem Ausführungsbeispiel näher dargestellt.The invention is described in more detail below using an embodiment.

Es wurden Partikel mit einer Anfangsfeuchte unter 20 % verwendet. Die verschiedenen Partikel-Wasserglas-Gemische wurden nacheinander aufgebracht, gemeinsam verdichtet und mit einem CO2-haltigen Heißgas, das quer durch die Probe geleitet wurde, ausgehärtet und getrocknet. Es wurde ein dreischichtiges Filter hergestellt:Particles with an initial moisture content of less than 20% were used. The various particle-water glass mixtures were applied one after the other, compacted together and cured and dried using a CO 2 -containing hot gas that was passed across the sample. A three-layer filter was produced:

1. Schicht Holzschneidspan1st layer of wood chippings

2. Schicht Holzfaserstoff (mittlerer Mahlgrad)2nd layer of wood pulp (medium grinding degree)

3. Schicht Holzfaserstoff (feiner Mahlgrad)3. Layer of wood pulp (fine grinding)

Bindemittel: Kali-Wasserglas 28/30
Gewichtsverhältnis Partikel : Kaliwasserglas = 1:1,2Binder: Potassium water glass 28/30
Weight ratio particles : potassium water glass = 1:1.2
