Abstract

Gas filter has the filter medium cleaned by a centrifugal effect. It consists of a drum to support the filter medium mounted along the flow axis having a hollow shaft through which the gas is sucked and which acts simultaneously as the drive. The filter medium can be sprayed from inside by a liq. in which case gas washing can be carried out. The centrifugal effect can be raised or lowered in proportion to the resistance to flow caused by cake build up. The drum can be accelerated to give the effect of several times the gravitational acceleration using time relays.

Description

Beschreibung und Erläuterung zur Patentanmeldung "RohgasreinigungsE ermit Zentrifugalabreinigung.'t Es ist bekannt, Rohgase durch Filterstoffe anzusaugen und den Staub an den Filtern anzulagern und abzurütteln oder abzublasen.Description and explanation of the patent application "RohgasreinigungsE ermit Zentrifugalabreinigung.'t It is known to suck in raw gases through filter materials and to accumulate the dust on the filters and shake off or blow off.

Nachstehend wird erfindungsgemäß ein Filter zur Rohgasreinigung, der trocken oder naß betrieben werden kann, erleutert, wobei erfindungsgemäß der Filterstoff auf einer Trommel aufgespannt ist und die auf dem Filterstoff sich anlagernden Staubteile durch Zentrifugalkraft nach außen bei Erreichung einer bestimmten Schichthöhe abgeschleudert werden und vorzugsweise von der Innenseite des Filters entsprechende Benetzungsflüssigkeiten aufgegeben werden, die wiederum durch ihre Zentrifugalkraft den auf dem Filterstoff außen aufgelagerten Schadstoff von innen her abdrücken.According to the invention, a filter for crude gas purification, the can be operated dry or wet, explained, according to the invention the filter material is stretched on a drum and the dust particles accumulating on the filter material thrown outwards by centrifugal force when a certain layer height is reached and preferably corresponding wetting liquids from the inside of the filter are abandoned, which in turn by their centrifugal force on the filter material Press off pollutants deposited on the outside from the inside.

In der beiliegenden Zeichnung ist eine solche erfindungsgemäße Anordnung dargestellt: mit 1: das ankommende Rohgas, mit 2: eine Drehtrommel, die in einem Gehäuse, das als Anströmrohr ausgebildet ist, gelagert ist, mit 3: der Drebtrommelantrieb, mit 4: der Ventilatorantrieb, mit 5: eine Filterstoffbespannung, mit 6: die Ansaughohlwelle, mit 7: der Staubaustrag, mit 8: der Flüssigkeitseinlauf für die Innenbesprühung des Zentr ifugaldrehtrommelfilters.Such an arrangement according to the invention is shown in the accompanying drawing shown: with 1: the incoming raw gas, with 2: a rotating drum that is in a Housing, which is designed as a flow pipe, is mounted, with 3: the rotary drum drive, with 4: the fan drive, with 5: a filter fabric covering, with 6: the suction hollow shaft, with 7: the dust discharge, with 8: the liquid inlet for internal spraying of the centrifugal rotary drum filter.

Arbeitsweise der erfindungagem~ßen Ausführung.Mode of operation of the embodiment according to the invention.

Das Rohgas wird bei 1 angesaugt und trifft auf den Filterstoff 5. Das gereinigte Gas wird über die Ansaughohlwelle 6 dem Ventilator zugeführt. Je nach Haftvermögen des Staubes wird über den Drehtroinmelantrieb 3 die entsprechende Zentrifugalkraft erzeugt, die ein mehrfaches der Erdbeschleunigung betragen kann.The raw gas is sucked in at 1 and hits the filter material 5. The cleaned gas is fed to the fan via the suction hollow shaft 6. Ever after the adhesion of the dust is about the rotary drum drive 3, the corresponding Centrifugal force generated, which can be several times the acceleration due to gravity.

Soll nicht nur Staub abgeschieden werden, so wird erfindungsgemäß in den Innenraum der Zentrifugaltrommel Wasser und/oder eine Emulsion bzw. eine Flüssigkeit eingesprüht, die zur chemischen Bindung, Waschung von Schadstoffen aus dem Rohgas und zur Abreinigung der agglomerierten Stäube beiträgt.If not only dust is to be separated, then according to the invention in the interior of the centrifugal drum water and / or an emulsion or a Sprayed liquid used for chemical binding, washing pollutants out contributes to the raw gas and to the cleaning of the agglomerated dusts.

Durch die ausstrdmende Flüssigkeit wird der Filter von innen beaufschlagt, und durch die Zentrifugalwirkung wird von innen nach außen auf das Filtermaterial eine zusätzliche Reinigungskraft durch die zentrifugierte Flüssigkeit erzeugt.The filter is acted upon from the inside by the outflowing liquid, and by the centrifugal effect inside out on the Filter material an additional cleaning power through the centrifuged liquid generated.

Der auf dem Filterstoff abgelagerte und angesaugte Staub kann zusätzlich über Schälmesserwirkungen abgereinigt werden.The dust deposited and sucked in on the filter material can also be cleaned off by peeling knife effects.

Selbstverständlich ist die Erfindung nicht auf die vorstehend im einzelnen dargestellten und beschriebenen Ausbildungsformen beschränkt, sondern es sind zahlreiche Abänderungen möglich, ohne jedoch von dem Grundgedanken abzuweichen, einen Rohgasreinigungsfilter so zu bauen, daß er durch Zentrifugalwirkung abgereinigt wird, wobei die Zentrifugalwirkung von innen durch Wasseranströmungen nach außen drückend unterstützt wird und erfordernisgerecht die Waschflüssigkeit entsprechend der zu reinigenden Schadstoffmenge zusätzliche Impfungen oder Emulsionen beinhalten kann.Of course, the invention is not limited to the above in detail Forms of training shown and described are limited, but there are numerous Modifications possible without deviating from the basic idea, a raw gas cleaning filter to be built so that it is cleaned by centrifugal action, the centrifugal action is supported from the inside by water flows to the outside and as required the washing liquid according to the amount of pollutants to be cleaned additional May include vaccinations or emulsions.
