Description

Emissjonselektrode for elektrofilter. Emission electrode for electrofilter.

Foreliggende oppfinnelse vedrører en emissjonselektrode for elektrofilter med horisontal gassgjennomstrømming, forsynt med 'Utstikkende emitterende elementer og bestående av et vertikalt opphengt, av platemateriale utført profil med et plant midtparti og oppbøyde eller opprullede kantlister. Da virkningsgraden av et elektrofilter er i høy grad avhengig av den anvendte spenning og da det kan bevises at virkningsgraden under fraskillelse av grov-ere støv, dvs. med en partikkelstørrelse over tiltar med kvadratet av spenningen, er det fordelaktig å utføre filtret således at spenningen kan holdes på den høyst mulige verdi. Med de hittil anvendte typer av emissjonselektroder kan spenningen riktignok holdes høy, men ved elektroder av denne art har det vist seg vanskelig å oppnå en gunstig strømtfordeling uten fare for over-slag. Særlig ved rensing av gasser med høy-motstands støv har denne ulempe gjort seg gjeldende. Oppfinnelsen — som tar sikte på en ny og forbedret utførelse av emissjonselektroder, som muliggjør en høy spenning i kombinasjon med gunstig strømfordeling med et større antall emitterende punkter pr. overflateenhet ■— utmerker seg ved at kantlistene er forsynt med et antall opp-pressede vorter som er bestemt til å danne elektrodenes hovedsakelige emitterende elementer. The present invention relates to an emission electrode for electrofilters with horizontal gas flow, provided with 'Protruding emitting elements and consisting of a vertically suspended profile made of plate material with a flat middle section and bent or rolled up edge strips. Since the efficiency of an electrofilter is highly dependent on the applied voltage and since it can be proven that the efficiency during the separation of coarser dust, i.e. with a particle size above increases with the square of the voltage, it is advantageous to design the filter so that the voltage can be kept at the highest possible value. With the types of emission electrodes used up to now, the voltage can indeed be kept high, but with electrodes of this type it has proved difficult to achieve a favorable current distribution without the risk of flashover. In particular, this disadvantage has become apparent when cleaning gases with high-resistance dust. The invention — which aims at a new and improved design of emission electrodes, which enables a high voltage in combination with favorable current distribution with a greater number of emitting points per surface unit ■— is distinguished by the fact that the edge strips are provided with a number of pressed-up warts which are destined to form the main emitting elements of the electrodes.

De oppressede vorter er i henhold til en utførelse av oppfinnelsen anbragt på elektrodens to kantlister og på hver av disse på hver sin side av elektrodens midtplan. En annen utførelse utmerker seg ved at de oppressede vorter er rettet i motsatt retning ved elektrodens to kantlister. Vortene kan i begge tilfelle være jevnt fordelt langs kantlistene, dvs. regnet i elektrodens høy-deretning, eller også være anbragt med en i høyderetningen differensiert, innbyrdes deling. According to one embodiment of the invention, the pressed warts are placed on the electrode's two edge strips and on each of these on either side of the electrode's center plane. Another design is distinguished by the fact that the raised warts are directed in the opposite direction at the two edge strips of the electrode. In both cases, the warts can be evenly distributed along the edge strips, i.e. counted in the direction of the height of the electrode, or they can also be arranged with a division between them that is differentiated in the direction of height.

Oppfinnelsen skal beskrives nærmere i tilslutning til tegningen som gjengir et elektrofilter med emissjonselektroder ifølge oppfinnelsen; fig. 1 viser et vertikalt lengdesnitt av et elektrofilter, fig. 2 og 3 i tverrsnitt alternative utførelser av emis-sjonselektrodene ogifig. 2a og 3a viser side-riss av disse utførelser tatt langs linjene II—II og III—III på fig. 2 hhv. 3. The invention shall be described in more detail in connection with the drawing which reproduces an electrofilter with emission electrodes according to the invention; fig. 1 shows a vertical longitudinal section of an electrofilter, fig. 2 and 3 in cross-section alternative embodiments of the emission electrodes andfig. 2a and 3a show side views of these designs taken along the lines II—II and III—III in fig. 2 respectively 3.

På tegningen angir 1 huset for et elektrofilter med et antall i parallelle rekker anordnede emissjonselektroder 2 som på kjent vis er svingbart opphengt i et ramme-verk 3. Elektrodene består av plateprofiler med et plant midtparti 3a og omrullende eller ombøyde kantlister 3b hhv. 3c, som nærmere vist på fig. 2 henholdsvis 3. Ifølge oppfinnelsen er elektrodene forsynt med emitterende elementer i form av langs kantlistene oppressede vorter 4. Disse kan, som fig. 2 viser, på hver kantlist være rettet til begge sider for elektrodens midtplan eller på den ene kantlist være rettet til en side og på den annen kantlist til den mot-satte side, som vist på fig. 3. For elektrodenes rengjøring er der på kjent vis anordnet In the drawing, 1 indicates the housing for an electrofilter with a number of emission electrodes 2 arranged in parallel rows, which are pivotably suspended in a framework 3 in a known manner. The electrodes consist of plate profiles with a flat middle part 3a and rolling or bent edge strips 3b or 3c, as shown in more detail in fig. 2 and 3 respectively. According to the invention, the electrodes are provided with emitting elements in the form of warts pushed up along the edge strips 4. These can, as fig. 2 shows, on each edge strip be directed to both sides of the middle plane of the electrode or on one edge strip be directed to one side and on the other edge strip to the opposite side, as shown in fig. 3. There are arrangements for cleaning the electrodes in a known manner
