Description

Elektrische Gasreinigungsanlage für Feinreinigung von Gasen. Bei den elektrischen Gasreinigungsanlagen hat es sich gezeigt, daß die Niederschlagswirkung, insbesondere für sehr feine Staubteilchen, in hohem Maße von der -lusbildung der Niederschlagselektroden abhängig ist, auf der sich die von den Hochspannungselektroden geladenen Staubteilchen absetzen sollen. Als besonders vorteilhaft hat sich dabei die Ausbildung von netzförmigen Elektroden erwiesen, die mit ihrer Ebene rechtwinklig zur Gasrichtung stehen, so daß die Gase durch die Maschen der Siebe hindurchtreten und dadurch in innige Berührung mit den Metallteilen der Elektrode gelangen.Electric gas cleaning system for fine cleaning of gases. Both electrical gas cleaning systems, it has been shown that the precipitation especially for very fine dust particles, to a large extent from the formation of the Precipitation electrode depends on the one on which the high-voltage electrodes are located should deposit charged dust particles. It has proven to be particularly advantageous the formation of reticulated electrodes turned out to be perpendicular to their plane face the gas direction so that the gases pass through the mesh of the sieves and thereby come into intimate contact with the metal parts of the electrode.

Es hat sich nun herausgestellt, daß die Wirkung derartiger netz- oder siebförmiger Elektroden besonders bei Feinreinigung von Gasen ganz erheblich gesteigert werden kann. wenn die siebförmigen Elektroden nicht als ebene Fläche gestaltet werden, sondern so, daß ihr Querschnitt zickzackförmig oder wellblechartig ausgebildet ist. Werden nämlich die netzförmigen Elektroden, wie bisher üblich, eben ausgeführt, so zeigen die in den Gasen enthaltenen feinen Schwebeteilchen namentlich bei hoher Gasgeschwindigkeit Neigung, durch die Maschen der Siebe hindurchzugehen, ohne mit dem Drahtgewebe selbst in Berührung zu 'kommen. Diese feinsten Staubteilchen werden auf Grund ihrer verhältnismäßig geringen elektrischen Ladung nur dann in genügend starkem Maße von den festen Teilen der Elektrode angezogen, wenn sie in allernächster Nähe die Siebe durchstreichen. Man könnte, um diesen Nachteil zu beseitigen, das Netzwerkenger wählen, doch tritt hierdurch der Nachteil eines großen Strömungswiderstandes für die Gase auf. Gestaltet man aber gemäß der Erfindung die Niederschlagselektrode zickzackförmig oder wellenförmig, so wird der freie geradlinige Durchgang für die vom Gasstrom getragenen Schwebeteilchen verhütet, da diese beim Anlaufen an die schief zur Strömung stehende Elektrodenfiäche stets auf einen Draht treff^n. Zu gleicher Zeit wird aber der Strömungswiderstand der Gitter gegenüber demjenigen ebener Elektroden in keiner Weise vergrößert, weil die Gesamtoberfläche der Elektroden sich vergrößert und mehr Durchtrittsstellen durch die Maschen geschaffen werden. Der Gesamtwirkungsgrad der Anlage wird daher bei Anwendung der Elektroden gemäß der Erfindung erheblich vergrößert, ohne daß der Strömungswiderstand erhöht wird.It has now been found that the effect of such network or sieve-shaped electrodes, especially in the case of fine cleaning of gases, considerably increased can be. if the sieve-shaped electrodes are not designed as a flat surface, but so that its cross-section is designed in a zigzag or corrugated sheet-like manner. If the net-shaped electrodes are designed to be flat, as has been the case up to now, so the fine suspended particles contained in the gases show especially at high levels Gas velocity tendency to pass through the mesh of the sieves without using to come into contact with the wire mesh itself. These are the finest dust particles because of their relatively low electrical charge only then in sufficient strongly attracted by the solid parts of the electrode when she Cross the sieves very close by. You could get around this disadvantage too Eliminate, choose the Netzwerkger, but this has the disadvantage of a large Flow resistance for the gases. But if you design according to the invention Precipitation electrode zigzag or wave-shaped, so the free straight one Passage for the suspended particles carried by the gas flow is prevented, as they are during the Always approach the electrode surface at an angle to the flow on a wire meet ^ n. At the same time, however, the flow resistance of the grid is opposite that of flat electrodes is in no way enlarged because the total surface area the electrodes are enlarged and more penetration points are created through the meshes will. The overall efficiency of the system is therefore reduced when the electrodes are used according to the invention significantly enlarged without increasing the flow resistance will.

Es sind zwar bereits zickzack- oder wellenförmige Elektroden in elektrischen Staubniederschlagsanlagen empfohlen worden, die ebenfalls aus Gitterwerk bestehen können. Diese Elektroden standen aber- nicht quer zum Gasstrom, sondern in der Richtung des Gasstromes. Hierbei tritt aber die günstige Wirkung gemäß der Erfindung nicht ein. Die feinen Staubteilchen bew:agen sich nämlich bei dieser bekannten Einrichtung fast ausschließlich in dem freien Raum zwischen je zwei solcher Elektroden, so daß der größte Teil von ihnen überhaupt nicht in die Nähe der iederschlagselektroden gelangt. Einrichtungen mit einer solchen Anordnung zickzackförmiger Elektroden sind daher gerade für die Beseitigung feiner Staubteilchen aus Gasen ungeeignet. Die wenigen Staubteile, die bei dieser bekannten Anordnung durch die Maschen der siebförmigen Elektroden hindurchtreten, sind im Verhältnis zur Gesamtmenge des Staubes so geringfügig, daßeine merkbare Verbesserung des- Wirkungsgrades hierdurch nicht zustande kommen kann. Erst wenn ;gemäß der Erfindung zickzack- oder wellenförmige Netzelektroden quer zum Gasstrom angeordnet werden, tritt die oben geschilderte günstige Wirkung in bezug auf die Reinigung der Gase ein.There are already zigzag or wave-shaped electrodes in electrical Dust precipitation systems have been recommended, which also consist of latticework can. However, these electrodes were not positioned at right angles to the gas flow, but in the same direction of the gas flow. In this case, however, the beneficial effect according to the invention does not occur a. The fine dust particles move in this known device almost exclusively in the free space between two such electrodes, so that most of them are nowhere near the precipitation electrodes got. Devices with such an arrangement of zigzag electrodes are therefore unsuitable for removing fine dust particles from gases. the few dust particles, which in this known arrangement through the mesh of the sieve-shaped Electrodes pass through are so insignificant in relation to the total amount of dust that that a noticeable improvement in efficiency does not come about as a result can. Only when; according to the invention, zigzag or wave-shaped mesh electrodes are arranged transversely to the gas flow, the beneficial effect described above occurs in relation to the purification of the gases.

In der Abbildung ist ein Ausführungsbeispiel der Erfindung schematisch dargestellt. In einer Reinigungskammer, bei der die Gase bei i eintreten und bei z heraustreten, sind die netzförmigen Niederschlagselektroden 3 angebracht, neben denen die Ladeelektroden 4. stehen. Die Niederschlagselektroden 3 sind gemäß der Erfindung- mit zickzackförmigem Querschnitt ausgebildet.In the figure, an embodiment of the invention is schematically shown. In a cleaning chamber where the gases enter at i and at z emerge, the net-shaped precipitation electrodes 3 are attached, next to where the charging electrodes are 4.. The collecting electrodes 3 are according to FIG Invention- designed with a zigzag cross-section.
