Bindemittel zur Adsorption gasförmiger Stoffe - Zusatz zuBinder for the adsorption of gaseous substances - addition to

Patentanmeldung P 30 19 550.7 Gefährliche Flüssigkeit, die in der Chemie in großer Vielzahl vorhanden ist, muß in vielen Fällen, insbesondere in Unglücksfällen, entfernt und unschädlich gemacht werden. Um dies zu erreichen, wurde in der Hauptanmeldung P 30 19 550.7 als synthetisches Chemikalien-Adsorbens ein Phenolharz-Schaumkunststoff vorgeschlagen.Patent application P 30 19 550.7 Dangerous liquid in the Chemistry is available in great variety, must in many cases, especially in accidents, removed and rendered harmless. To achieve this, the main application P 30 19 550.7 a phenolic resin foam plastic as a synthetic chemical adsorbent suggested.

Gefährliche chemische Stoffe bilden nicht lediglich im flüssigen Zustand eine Gefahr, sondern auch in deren gasförmiger Phase. Auch sind in atmosphärischer Luft nicht nur feste oder flüssige, sondern auch gasförmige Verunreinigungen vorhanden. Dies ist nicht lediglich der Fall in chemischen Fabriken oder chemischen Labors. Auch die Abluft aus Gebäuden oder Fabrikationsstätten bedarf der Reinigung-. Diese gasförmigen Stoffe, auch als Beimengungen zur Luft, sind je nach chemischer Zusammensetzung übelriechend, unangenehm, gesundheitsschädlich oder toxisch. Es ist daher notwendig, diese zu entfernen.Hazardous chemical substances do not only form in the liquid state a danger, but also in its gaseous phase. Also are in more atmospheric Air contains not only solid or liquid, but also gaseous impurities. This is not just the case in chemical factories or chemical laboratories. The exhaust air from buildings or factories also needs cleaning. These Gaseous substances, also as admixtures to the air, are depending on their chemical composition malodorous, unpleasant, harmful or toxic. It is therefore necessary remove them.

Da sich meistens mit mechanisch wirkenden Luftfiltern nicht alle gasförmigen luftfremden Stoffe beseitigen lassen, werden vielfach Aktivkohlefilter verwendet, auch in Verbindung mit mechanisch wirkenden Luftfiltern, damit die mechanisch wirkenden Luftreinigungsanlagen die zu säubernde Luft zu nächst von darin enthaltenen festen oder flüssigen Verunreinigungen befreien, damit diese nicht die Aktivkohleschichtzusätze und somit deren eigentliche Funktion, nämlich Abscheidung gasförmiger Verunreinigungeng infrage stellen.Since mostly mechanically acting air filters are not all gaseous remove pollutants from the air, activated carbon filters are often used, also in connection with mechanically acting air filters, so that mechanically acting ones Air purification systems the air to be cleaned next from the solid contained therein or free liquid contaminants so that they do not remove the activated carbon layer additives and thus their actual function, namely the separation of gaseous impurities to question.

Viele gasförmige Stoffe lassen sich an Aktivkohle nicht binden, so daß keine Adsorption-vorhanden ist. Dies gilt beispielsweise für Fluor F2 Kohlenmonoxid CO Nypton KR Luft (C02-frei) Methan CH2 Sauerstoff O, Stickoxid NO Stickstoff N2 Wasserstoff H.Many gaseous substances cannot be bound to activated carbon, like this that there is no adsorption. This applies, for example, to fluorine F2 carbon monoxide CO Nypton KR air (C02-free) methane CH2 oxygen O, nitrogen oxide NO nitrogen N2 Hydrogen H.

Bei vielen anderen Stoffen ist die Adsorption nur mäßig9 so für Ammoniak NH2 Äthan C2H6 Azetylen C2H2 Butan C4Hz3 Chlor C12 Kohlendioxid CO, Methylchlorid CH3C1 Tetrachlorkohlenstoff C(:l2 Propan C3H3 Propylen C3H6 Schwefeldioxid S2 Schwefelwasserstoff H,S Stickoxidul N20 Xenon Xe Die vorliegende Erfindung geht von der Aufgabe aus, ein Bindemittel zur Adsorption gasförmiger Stoffe zu schaffen, das der Adsorptionsfähigkeit der Aktivkohle gegenüber besser ist und anstelle von pulverförmiger Aktivkohle als Adsorbens für Adsorptionsfilter geeignet ist.With many other substances the adsorption is only moderate9 for ammonia NH2 ethane C2H6 acetylene C2H2 butane C4Hz3 chlorine C12 carbon dioxide CO, methyl chloride CH3C1 Carbon tetrachloride C (: l2 propane C3H3 propylene C3H6 sulfur dioxide S2 Hydrogen Sulphide H, S Nitrogen Oxide N20 Xenon Xe The present invention works starting from the task of creating a binding agent for the adsorption of gaseous substances, that the adsorption capacity of the activated carbon is better than and instead of powdered activated carbon is suitable as an adsorbent for adsorption filters.

Zur Lösung dieser Aufgabe wird als-Bindemittel für gasförmige Stoffe ein Phenolharz-Schaumkunststoff vorgeschlagen, der vorzugsweise in Pulverform vorliegt und offenzellig oder geschlossenzellig ist.To solve this problem is used as a binder for gaseous substances proposed a phenolic resin foam plastic, which is preferably in powder form and is open-cell or closed-cell.

Es wurde erkannt, daß gehärteter Phenolharz-Schaumkunststoff nicht lediglich flüssige Stoffe bindet, sondern auch gasförmige Stoffe und somit unter anderem auch zur Reinigung von Luft verwendbar ist. Auch hat sich gezeigt, daß die Bindungskapazität pulverförmigen ausgehärteten Phenolharzschaumkunststoffes wesentlich größer ist als die von Aktivkohle, so daB in weiterer erfindungsgemäßer Ausgestaltung die Phenol harz-Schaumkunststoff-Parti kel auch zur Abluftreinigung verwendet werden.It has been recognized that cured phenolic foam plastic does not only binds liquid substances, but also gaseous substances and thus under can also be used to purify air, among other things. It has also been shown that the Binding capacity of powdery cured phenolic resin foam plastic is essential is greater than that of activated carbon, so that in a further embodiment according to the invention The phenolic resin-foam plastic particles can also be used for exhaust air purification.

Mit dem Phenolharz-Schaumstoff lassen sich alle jene Stoffe im gasförmigen Zustand adsorbieren, die auch durch Kohle adsorbiert werden, wobei die Wirkung des Phenolharz-Schaumstoffes jedoch bedeutend höher ist.With the phenolic resin foam, all those substances can be converted into gaseous Adsorb state that are also adsorbed by charcoal, whereby however, the effect of the phenolic resin foam is significantly higher.

Auch lassen sich nunmehr gasförmige Stoffe adsorbieren, die durch Aktivkohle nicht gebunden werden konnten.Gaseous substances can now also be adsorbed through Activated carbon could not be bound.

In weiterer erfindungsgemäßer Ausgestaltung wird vorgeschlagen, daß gemahlener offenzelliger oder geschlossenzelliger Phenolharz-Schaumstoff mit Aktivkohle gemischt ist. Auch kann der Phenolharz-Schaumstoff in Kombination mit Aktivkohle in Filterpatronen angeordnet sein, d. h. daß der gasförmige Stoff zunächst den Phenolharzschaumstoff durchwandert und anschließend Aktivkohle und schließlich wieder einen Phenolharzschaumstoff.In a further embodiment of the invention it is proposed that ground open-cell or closed-cell phenolic resin foam with activated carbon is mixed. The phenolic resin foam can also be used in combination with activated carbon be arranged in filter cartridges, d. H. that the gaseous substance is first the phenolic resin foam wandered through and then activated carbon and finally again a phenolic resin foam.

Ein weiterer erfindungsgemäßer Vorschlag geht dahin, daß der gemahlene Phenolharz-Schaumstoff in eine Schaumstoffplatte aus Polyäther oder Polyesther-Schaum gebettet ist.Another inventive proposal is that the ground Phenolic resin foam in a foam sheet made of polyether or polyester foam is bedded.

Eine weitere Lösung beinhaltet, daß der gemahlene vorzugsweise offenzellige Phenolharzschaum durch ein Bindemittel zu einem Formkörper gebunden ist, wobei das Bindemittel jedoch ausreichend gasdurchlässig ist.Another solution implies that the ground is preferably open-celled Phenolic resin foam is bound by a binder to form a molded body, the However, the binder is sufficiently gas-permeable.

Auch kann der gemahlene Phenolharzschaum in einem gasdurchlässigen Beutel, insbesondere aus thermoplastischer Kunststoffolie, angeordnet sein. Dann ist dieser Beutel vorteilhaft von einem schützenden Sieb umgeben, das vorzugsweise weiterhin von einem Vliesstoff umgeben ist.The ground phenolic resin foam can also be gas-permeable Bags, in particular made of thermoplastic plastic film, can be arranged. then this bag is advantageously surrounded by a protective screen, which is preferably is still surrounded by a nonwoven fabric.

Der Phenolharzschaumstoff kann auch in Gestalt einer Platte vorhanden sein, die mit zahlreichen Lochungen versehen ist. ZweckëBig sind die Lochungen dann mit geringem Durchmesser durchgehend.The phenolic resin foam can also be in the form of a plate be, which is provided with numerous holes. The perforations are then useful with a small diameter throughout.

Die Platte aus Phenolharzschaum kann im Querschnitt aus einer Halbschale oder eine Rinne bestehen.The panel made of phenolic resin foam can have a half-shell in cross section or a gutter.

Die Erfindung ist in der Zeichnung beispielhaft dargestellt. Es zeigen: Fig. 1 einen Kanal mit einem Filter aus gehärtetem gemahlenen Phenolharzschaumstoff in vertikalem Schnitt, Fig. 2 eine Abwandlung der Fig. 1, Fig. 3 einen Kanal in vcrtikdlesl Schnitt mit verschiedenen Illit Uohrunqen oder Lochungen versehenen Phenolharzschaumstoffplatten, Fig. 4 in einem Kanal versetzt hintereinander angeordnete Phenol harzschaumstoffpl atten, Fig. 5 in einem Kanal in vertikalem Schnitt schalenförmige Phenolharzschaumstoffplatten, Fig. 6 in einem Kanal und vertikalem Schnitt Patronen mit einer Füllung von gemahlenem Phenolharzschaumstoff.The invention is shown by way of example in the drawing.

Mit 10 ist ein Kanal bezeichnet, in dem gemahlener Phenolharzschaumstoff 11 angeordnet ist, der nach der Darstellung in Fig. 1 in einem Behälter 12 angeordnet ist, der luftdurchlässig ist. Bei diesem Behälter 12 kann es sich um ein Gewebe handeln, aber auch um einenmit zahlreichen Mikrolochungen versehenen Beutel aus thermoplastischer Kunststoffolie.With a channel 10 is referred to in the ground phenolic resin foam 11 is arranged, which is arranged in a container 12 as shown in FIG that is permeable to air. This container 12 can be a fabric but also a bag with numerous micro-perforations thermoplastic plastic film.

Die zu reinigende Luft ist symbolisch mit Pfeil 13 dargestellt. Sie führt schadli<he Gase mit sich, die durch die Phenolharzschaumstoffkörper 11 in Pulverform adsorbiert werden. In dem Behälter 1? können die Pheiiolharzschaumstoffpartikel auch unit Partikeln (iUS Aktivkohle gemischt ein.The air to be cleaned is shown symbolically with arrow 13. she carries harmful gases with it, which through the phenolic resin foam body 11 in Powder form to be adsorbed. In the container 1? can they Pheiiolharzschaumstoffpartikel also unit particles (iUS activated carbon mixed a.

Fig. 2 zeigt eine Fig. 1 vergleichbare Lösung, jedoch mit der Maßgabe, daß die Phenolharz-Schaumstoffpartikel 11 umgeben sind von einem Vlies, das die Aufgabe hat, im Luftstrom vorhandene Festkörper zu binden.FIG. 2 shows a solution comparable to that of FIG. 1, but with the proviso that that the phenolic resin foam particles 11 are surrounded by a fleece that the Has the task of binding solids present in the air flow.

Fig. 3 zeigt, daß eine Platte aus henolhrzschaulstoff vorhanden ist.Fig. 3 shows that there is a plate made of henolhrzschaulstoff.

Diese kann bei der üblichen Herstellung des (lehärteten Phenolharzschaumes mit offenzelliger Struktur enthalten sein. Es ist jedoch auch vorteilhaft, daß die Platte aus einem geniahlenen offenzelligen oder geschlossenzelligen Phenolharzschaumstoff gebildet ist, wobei diese Schaumkunststoffpartikel dann durch Bindemittel, beispielsweise ein Kunstharze miteinander so verbunden sind, daß das Bindemittel gasdurchlässig ist. Durch diese Lösung wird die Adsorptionsfähigkeit sehr erhöht.This can be done during the usual production of the hardened phenolic resin foam be included with an open-cell structure. However, it is also advantageous that the Panel made from an ingenious open-cell or closed-cell phenolic resin foam is formed, these foam plastic particles then by binding agents, for example a synthetic resin are connected to one another in such a way that the binder is gas-permeable is. This solution greatly increases the adsorption capacity.

Fig. 3 zeigt im rechten Teil, dath in der Platte 14 an gegenüberliegenden Seiten nicht durchgehende Bohrungen 16 oder dergleichen Vertiefungen 16a vorhander sind9 enen die Aufgabe zukommt, für die zu adsorbierenden Gase eine möglichst große Angriffsfläche zu bilden.Fig. 3 shows in the left part that in the plate 14 through holes 15 low rating are available. Fig. 3 shows in the right part, dath in the Plate 14 on opposite sides not through holes 16 or the like Wells 16a are present and have the task of being adsorbed Gases to form the largest possible attack surface.

Fig. 4 zeigt. daß Platten aus Phenolharzschaumkunststoff in Abständen hintereinander angeordnet sind. Dargestellt sind drei Reihen solcher Platten mit Zwischenräumen, die eine gewissse Umlenkung und Durchwirbelung der zu reinigenden Luft ermöglichen, um dadurch viele Anlageflächen an den Phenolharzschaumstoffkörpern zu finden. Auch diese sind zweckmäßig aus gemahlenem offenzelligen Phenolharzschaum in Verbindung mit einem die Partikel zusammenhaltenden rinder hergestellt.Fig. 4 shows. that panels made of phenolic resin foam plastic at intervals are arranged one behind the other. Three rows of such plates are shown Interstices that cause a certain deflection and whirling of the areas to be cleaned Allow air to thereby create many contact surfaces on the phenolic resin foam bodies to find. These too are functional ground open-cell Phenolic resin foam produced in conjunction with a cattle holding the particles together.

Fig. 5 zeigt, daß die Platten au Phenolharz-Schaumkunststoff 14, 14a im Querschnitt schalen- oder rinneifönnig ausgebildet sind.Fig. 5 shows that the panels made of phenolic resin foam plastic 14, 14a are designed in cross-section with a bowl or groove.

Fig. 6 zeigt, ddlJ gemahlener Phenolhar/Schaum auch ggf. in Verbindung mit Aktivkohle, in Patronen 17, 1 angeordnet ist, die vorne und hinten durch luftdurchlässige Deckel 19 und 20 verschlossen sind.FIG. 6 shows the ground phenolic resin / foam, possibly also in combination with activated carbon, arranged in cartridges 17, 1, the front and rear through air-permeable Lids 19 and 20 are closed.

Es sind mehrere solcher Patrone so angeordnet, daß zwischen diese keine Luft durchdringen kann.There are several such cartridge so that between them no air can penetrate.

Die erfindungsgemäße Lösung, als Adsorptionsmittel für gasförmige, gesundheitsgefährende oder in sonstiger Weise gefährliche Stoffe gemahlenen, gehärteten Phenolharzschauni zu verwenden, hat den Vorteil, daß die Adsorptionsfähigkeit von der Luftfeuchtigkeit weitgehend unabhängig ist und eine bisher nicht erreichbare und nicht voraussehbare Adsorptionsfähigkeit vorhanden ist.The solution according to the invention, as an adsorbent for gaseous, ground, hardened substances that are hazardous to health or otherwise dangerous Using phenolic resin Schauni has the advantage that the adsorption capacity of the humidity is largely independent and a previously unattainable one and unpredictable adsorptive capacity is present.

Die Phenolharz-Schaumstoffpartikel dienen somit als Filterstoff zur Adsorption von gasförmigen Stoffen, als Trennmittel oder zur Abscheidung flüssiger und gasförmiger Stoffe aus der Luft. Es sei somit festgestellt, daß nicht lediglich die reine gasförmige í'hdse adsorbiert wird, sondern daß auch zusätzlich noch flüssige Autelle in der Luft vorhanden sein können, die ebenfalls adsorbiert werden.The phenolic resin foam particles thus serve as a filter material for Adsorption of gaseous substances, as a separating agent or for the separation of liquids and gaseous substances from the air. It should therefore be noted that not merely the pure gaseous í'hdse is adsorbed, but that also liquid Autelle may be present in the air, which are also adsorbed.

Sofern aus der Luft Fette adsorbiert werden sollen, dann empfiehlt sich die Verwendung von gemahlenen Phenolharzschaumpartikeln, die geschlossene Zellen haben. Dämpfe von Säuren oder Basen und solche mit einem Anteil an Wasser werden vorteilhaft mit gemahlenen Phenolharzschaumpari ikeln mit offenen Zellen adsorbiert.If fats are to be adsorbed from the air, then recommended the use of ground phenolic foam particles that form closed cells to have. Vapors from acids or bases and those with a proportion of water will be advantageously adsorbed with ground phenolic resin foam parisons with open cells.
