Abstract

The filter apparatus for on- and off-line operation contains several regenerating devices (3, 4). Air filter elements are cleaned either by a reverse flow cycle or an agitation by which the element is struck impulsively. The former is called on-line regeneration and the latter off-line regeneration. Off-line regeneration requires intermittent operation. It is however of value in the manufacture of loose materials where the dust on the elements can form bridges. A combined system is therefore proposed where air is blown into the elements and a framework holding the elements is struck impulsively by a rotating arm. The processes may be carried out simultaneously or at independent intervals.

Description

Stand der TechnikState of the art

In der Schüttgut Herstellung und Verarbeitung werden immer häufiger feinere Schüttgüter und Stäube eingesetzt. Dadurch kommt es zu immer mehr Staubentwicklung die nicht in die abgegeben werden kann und darf. Aus diesem Grunde werden immer mehr Filtrationsapparate mit mechanischer Trennung eingesetzt. Jetzt soll der Filterapparat permanent zur Trennung zu Verfügung stehen. Die wachsende Filterschicht führt zu einem stetigem ansteigen des Filterwiderstandes. Um den Filterwiderstand unter Kontrolle zu bekommen werden unzählige Regenerationsverfahren eingesetzt. Grundsätzlich unterscheidet die Fachwelt zwischen Off-Line und On-Line Betrieb. Die offline-Filtereinheit-Reinigung findet mechanisch statt und kann nur im Stillstand der Luftführung, also keine Rohgasführung, durchgeführt werden. Unzählige Verfahren und Reinigungsanordnungen sind bekannt. Die unzähligen Regenerierungsverfahren sind begründet auf der Suche nach einer möglichst langen konstanten Druckdifferenz beim Filtriervorgang. In den letzten Jahren verbreitet sich die Druckluftstoß immer mehr. Die neueste Technik ist die Druckdifferenz abhängige Regenerierung in Verbindung mit der Druckluftreinigung. Alle haben jedoch den Nachteil, daß die offline-Regeneration der Filterfläche ein online-Betrieb ausschließt. Dadurch wird der Vorteil der online-Regenereration und der Vorteil offline-Regeneration im einem Filterapparat ausgeschlossen. Es ist bekannt, daß viele Schüttgutbehälter mit harten Gegenständen traktiert werden, um anhaftendes Produkt von den Oberflächen in der Rohgaskammer abzulösen und auszutragen. Teilweise bildet das Schüttgut außerdem Brücken. Diese werden ebenfalls mit harten Gegenständen traktiert. Dies kann automatisiert werden, durch Anbringung von einer Vibration-, Rüttel- und Druckluftvorrichtung an der Rohgasraum. Diese dienen zum Auslauf des Produktes und zur Brückenauflösungen. Wie unter anderem in Fachzeitschriften berichtet wird ein Betrieb während der mechanischen Regeneration (offline-Betrieb) der Filterfläche nicht möglich.In bulk goods manufacturing and processing, finer bulk goods and dusts are becoming increasingly common used. This leads to more and more dust that does not get into the can and may be delivered. For this reason, more and more filtration devices are being used mechanical separation used. Now the filter apparatus should be permanently closed for separation To be available. The growing filter layer leads to a steady increase in the Filter resistance. To get the filter resistance under control, countless Regeneration process used. The professional world distinguishes between off-line and On-line operation. The offline filter unit cleaning takes place mechanically and can only be carried out when the machine is at a standstill the air flow, i.e. no raw gas flow. Countless procedures and Cleaning arrangements are known. The countless regeneration processes are based on looking for the longest possible pressure difference during the filtering process. In the last For years, the blast of compressed air has spread more and more. The latest technology is the pressure difference dependent regeneration in connection with compressed air cleaning. However, all have the disadvantage that the offline regeneration of the filter surface precludes online operation. This is the advantage online regeneration and the advantage of offline regeneration in one filter device locked out. It is known that many bulk containers are trapped with hard objects to detach adhering product from the surfaces in the raw gas chamber and to carry out. Some of the bulk goods also form bridges. These are also hard Objects traced. This can be automated by attaching a vibration, Vibration and compressed air device at the raw gas room. These serve to discontinue the product and for bridge resolutions. As reported, among other things, in trade journals, an operation is carried out during mechanical regeneration (offline operation) of the filter surface is not possible.

AufgabenstellungTask

Daraus ergibt sich die Aufgabenstellung, ein Verfahren und Vorrichtung zu finden, die die Vorteile der offline-Regeneration und der online-Regeneration und somit die gegensätzliche Betriebsweise in einem Filterapparat vereint und die Zusatzaufgaben des Produktauslaufes mit übernimmt. This gives rise to the task of finding a method and device that takes advantage of offline regeneration and online regeneration and thus the opposite mode of operation in combined in a filter apparatus and takes over the additional tasks of the product outlet.  

Lösungsolution

Mit diesem neuartigen Kombinations-Regenerationsverfahren ist es möglich den Filterapparat sowohl im Off-Line oder im On-Line Betrieb zu betreiben, oder Off-Line und On-Line kombiniert zu betreiben. Es kommt zusätzlich zu überraschenden Regenerationsergebnisse bei gleichzeitigem Betrieb der beiden Verfahren. Bei dieser neuartigen Idee den Nachteil durch Kombination mit dem On-Line Betrieb zu kompensieren kommt es zu unerwarteten Ergebnisse; die Rückstandsmenge im Rohgasraum 1 wird deutlich reduziert. Die Rückstandsmenge auf der Filtereinheit 2 wird deutlich geringer. Der Reingaswert im Reingasraum 5 wird dadurch nicht nachteilig beeinflußt. Es kann auf die zusätzlichen Auslaufshilfen verzichtet werden. Häufig sind im Rohgasraum 1 zusätzlich Auslaufshilfen eingebaut; diese können entfallen. Die Konstruktion löst dies dadurch, daß im Reingasraum 5 abluftseitig eine Druckluftreinigung [On-Line Druckluftregenrationsvorrichtung 3] für den online Betrieb und eine Klopfreinigung für den Off-Line Betrieb [Off-Line Regenerationsvorrichtung 4] gemeinsam untergebracht ist. Diese Kombination läßt zu, daß Filterapparate im Grenzbereich von off- und online Betrieb eingesetzt werden können. Die Rohgaskammer mit der Filtereinheit wird optimal regeneriert und gereinigt. Nach der Regenerierung befinden sich kaum mehr Schüttgüter und Filtratrückstände in der Rohgaskammer (1). Durch diese Kombination sind Störungen durch Rückstau in der Rohgaskammer 1 um ein Vielfaches weniger geworden, gegenüber der bis jetzt üblichen entweder im off- oder im online betriebenen Filterapparate.With this innovative combination regeneration process, it is possible to operate the filter apparatus both in off-line or in on-line mode, or to operate off-line and on-line in combination. In addition, there are surprising regeneration results when the two processes are operated simultaneously. With this new idea to compensate for the disadvantage by combining it with online operation, unexpected results are obtained; the amount of residue in the raw gas room 1 is significantly reduced. The amount of residue on the filter unit 2 becomes significantly less. The clean gas value in the clean gas space 5 is not adversely affected thereby. The additional outlet aids can be dispensed with. Outlet aids are often installed in the raw gas space 1 ; these can be omitted. The construction solves this in that a compressed air cleaning [online compressed air regeneration device 3 ] for online operation and a knock cleaning for offline operation [off-line regeneration device 4 ] is housed together in the clean gas space 5 on the exhaust air side. This combination allows that filter devices can be used in the border area of offline and online operation. The raw gas chamber with the filter unit is optimally regenerated and cleaned. After regeneration, there are hardly any bulk goods and filtrate residues in the raw gas chamber ( 1 ). Through this combination, disturbances due to backflow in the raw gas chamber 1 have become many times less than in the filter apparatus operated up to now, either in off-line or in online mode.
