Description

Aus endlosen Filterbändern bestehendes Plattenluftfilter Zusatz zum Patent 493 185 Die vorliegende Erfindung bezieht sich auf ein aus elidlosen Filterbändern bestehendes Plattenluftfilter, dessen Drehungsebene quer zur Luftströmungsrichtung liegt, nach Patent 493 185. Derartige Plattenluftfilter werden speziell in Kokereien verwendet.Plate air filter, consisting of endless filter belts, addition to the U.S. Patent 493,185 The present invention relates to an elideless filter belt Existing plate air filter, the plane of rotation of which is perpendicular to the direction of air flow is, according to patent 493 185. Such plate air filters are especially in coking plants used.

Bei den bisherigen Filtern für derartige Zwecke wurden vorzugsweise wasserbenetzte Siebtrommeln verwendet. deren Nachteile darin bestehen. daß die Siehe sich sehr bald verstopfen und dadurch einen hohen Druck verlust erzeugen. Weiterhin besteht der Nachteil, daß in den gereinigten Gasen bzw. der gereinigten Luft leicht Feuchtigkeitströpfchen der für die Filterplaten verwendeten Netzflüssigkeit mitgerissen werden. In the previous filters for such purposes were preferred water-wetted sieve drums are used. the disadvantages of which are. that the see become clogged very quickly and thus create a high pressure loss. Farther there is the disadvantage that easily in the purified gases or the purified air Droplets of moisture in the wetting liquid used for the filter plates are carried away will.

Diese Nachteile werden auf Grund der vorliegenden Erfindung vermieden und weitere sehr erllebliche technische Vorteile dadurch erzielt, daß in dem Filtergehäuse. ill der Luftströmungsrichtung gesehen. hinter dem flüssigkeitsbenetzten Plattenfilter ein gegebenenfalls mit Auflagen aus aufsaugendem Stoff versehenes Trockenplattefilter derart angeordnet ist, daß die Drehachsen beiden Filtern gemeinsam sind. und daß ferner zwischeit beiden Filtern eine Heizvorrichtung eingebaut ist. Hierdurch wird insbesondere der Vorteil erzielt, daß das Trockenfilter durch ständiges Vorbeiführen an der Heizvorrichtung auch bei plötzlich erhöhter Luftgeschwindigkeit stets getrocknet wird. Durch die Kombination These disadvantages are avoided on the basis of the present invention and other very tangible technical advantages achieved in that in the filter housing. ill seen the direction of air flow. behind the liquid-wetted plate filter a dry plate filter, optionally provided with covers made of absorbent material is arranged such that the axes of rotation are common to both filters. and that Furthermore, a heating device is installed between the two filters. This will in particular, the advantage achieved that the dry filter by constantly passing by Always dried on the heating device even when the air speed suddenly increased will. By combining

des Trocken- und Naßfilters gemäß der Erwindung mit gemeinsamem Antriebmechanismus und gemeinsamer Heizvorrichtung werden also besonders voeteilhafte Wirkungen gerade bei derjenigen Gattung von Filtern erreicht, auf welche sich das Hauptpatent 493 185 bezieht. Man hat zwar schon bei berieseltem Gasreiniger, dessen Filterkästen ruhend angeordnet sind, einen nachgeschalteten Trockenreiniger vorgesehen. Bei diesem Filter bestand aber keine Gewähr dafür. daß nicht die feuchte Luft durch die trockenen Reinigungsbleche hindurchgetrieben wird.of the dry and wet filter according to the invention with a common drive mechanism and a common heating device are therefore particularly advantageous effects achieved in the type of filter to which the main patent 493 185 refers. You already have its filter boxes when the gas cleaner is sprinkled are arranged resting, a downstream dry cleaner is provided. With this one Filter was no guarantee for it. that not the moist air through the dry Cleaning plates is driven through. Dies ist aber mit Sicherheit bei dem Filter nach der Erfindung vermieden. Ein weiterer Vorteil des Filters nach der Erfindung besteht darin, daß der an dem Naßfilter abgeschiedene Staub niemals mit dem Trockenfilter in Berührung und daher auch nicllt in den zu schützenden Raum gelangen kann. Im übrigen werden die mitgerissenen Fliissigkeitströpfchen mittels der aus aufsungendem Stoff bestehenden Auflagen auf den Filterplatten festgehalten. Mittels der Heizvorricbtung werden einerseits die Filterplatten des Feinfilters rasch getrocknet und aufnahmefähig erhalten und andererseits wird die Reinigungsflüssigkeit des Hauptfilters angewärmt. wodurch deren Wirksamkeit auf die Platten des Hauptfilters wesentlich gefördert wird.However, this is definitely avoided in the case of the filter according to the invention. Another advantage of the filter according to the invention is that the Dust separated from the wet filter never comes into contact with the dry filter and therefore also cannot get into the room to be protected. Otherwise, the carried away Liquid droplets by means of the pads consisting of absorbing material held on the filter plates. By means of the Heizvorricbtung on the one hand the Filter plates of the fine filter dried quickly and received and on the other hand the cleaning fluid of the main filter is warmed up. thereby their effectiveness is significantly promoted on the plates of the main filter. Die Zeichnung zeigt, und zwar iu den Abb. t und 3 im senkrechten bzw. waagerechten Schnitt und Abb. 2 in Aufsicht. ein Ausführungsbeispiel des Plattenluftfilters nach der Erfindung, bei welchem die Drehungsebene des aus cinem endlosen Filterband bestellenden Filters quer zur Luftströmungsrichtung liegt und die Luftfilter paketweise aufeinandergestapelt sind. The drawing shows, namely iu the Fig. T and 3 in the vertical or horizontal section and Fig. 2 in plan. an embodiment of the plate air filter according to the invention, in which the plane of rotation of the endless filter belt made of cinem The filter ordered is perpendicular to the direction of air flow and the air filter is packaged are stacked on top of each other. Wie ersichtlich, ist hinter dem aus einem endlosen Band bestehenden Reinigungsfilter r ein Feinfilter 1 angeordnet welches ebenfalls aus einem endlosen Bande bestellt. l)er Antrieb sowohl des Reinigungsfilters r wie auch des Feimilters f erfolgt von den gemiensamen Drehachsen d1 und d2, über welche die Kettenglieder der beiden Filter geführt sind. As can be seen, is behind the one consisting of an endless band Cleaning filter r a fine filter 1 arranged which also consists of an endless Gang ordered. l) it drives both the cleaning filter and the fine filter f takes place from the common axes of rotation d1 and d2, over which the chain links of the two filters are performed. Die zu reinigende Luft tritt aus a in das Filter ein, streicllt durch das Reinigungsfilter r und das Feinfilter f und verläßt die Vorrichtung bei b. Die Filterplatten des Reinigungsfilters r werden durch die Netzflüssigkeit ii (vgl. Abb. 1 und 2) paketweise fortlaufend hindurchgeführt. Mittels der Kette k werden die einzelnen Plattenpakete um die Achsen d1 und d3 abgehoben und durch die Netzflüssigkeit hindurchgeschwenkt. Die einzelnen Platten sind quer zur Strömungsrichtung der Luft bzw. des Gases geriffelt, wie dies aus Abb. 3 ersichtlich. Die Platten des Feinfilters f sind versetzt zueinander angeordnet und mit Auflagen aus aufsaugendem Stoff versehen.The air to be cleaned enters the filter from a and passes through the cleaning filter r and the fine filter f and leaves the device at b. the The filter plates of the cleaning filter r are affected by the net liquid ii (cf. Fig. 1 and 2) continuously passed through in packets. By means of the chain k the individual plate packs are lifted off around the axes d1 and d3 and passed through the network fluid swiveled through. The individual plates are perpendicular to the direction of air flow or the gas corrugated, as can be seen from Fig. 3. The plates of the fine filter f are offset from one another and provided with pads made of absorbent material. Die Heizvorrichtung h besitzt die Gestalt einer Heizschlange. mittels derer sowohl die Netz. flüssigkeit wie auch die Filterplatten des Feinfilters angewärmt werden. Hierdurch wird die Wirksamkeit des Filters wesentlich gesteigert, da insbesondere die Platten des Feinfilters fortlaufend trocken erhalten bleiben.The heating device h has the shape of a heating coil. by means of which both the network. liquid as well as the filter plates of the fine filter are warmed up will. This significantly increases the effectiveness of the filter, since in particular the plates of the fine filter remain continuously dry. Der gemeinsame Antrieb sowohl des Reilligungsfilters wie auch des Feinfilters erfolgt mittels des Motors m, welcher über ein Triebwerk @ die Drehachsen d1 und d2 antreibt.The common drive of both the cleaning filter and the Fine filter takes place by means of the motor m, which drives the axes of rotation via a motor @ drives d1 and d2. P A T E N A N S P R U C H: Aus endlosen Filterbändern bestehendes Plattenluftfilter, dessen Drehungsebene qucr zur Luftströmungsrichtung liegt. nach Patent 493 185. dadurch gekennzeichnet, daß in dem Filtergehäuse. in der Luftströmungsric.htung gesehen, hinter dem flüssigkeitsbenetzten Plattenfilter (r) ein gegebenenfalls mit Auflagen aus aufsaugendem Stoff versehenes Trockenplattenfilter (f) derart angeordnet ist, daß die Drehachsen beiden Filtern gemeinsam sind und daß ferner zwischen beiden Filtern eine Heizvorrichtung (h) eingebaut ist.
