Description
Beheizung der Isolatoren eines Elektrofilters Bei elektrischen Gasreinigungsanlagen sind gewöhnlich die Isolatoren in besonders beheizten, von der Reinigungskammer getrennten Nebenkammern untergebracht. Es soll dadurch erreicht «-erden, daß die Isolatoren, insbesondere ihre Oberfläche, auf einer so hohen Temperatur gehalten werden, daß sich auf den Isolatoren keine Kondensationsniederschläge bilden, die leicht unerwünschte Stromübergänge herbeiführen könnten. Man hat auch vorgeschlagen, die Isolatoren zu diesem Zweck durch Heizvorrichtungen zu erwärmen, die im Innern der Isolatoren angeordnet sind. Es kann nun vorkommen, daß diese zusätzliche Heizvorrichtung für die Isolatoren einmal aus irgendeinem Grunde versagt und infolgedessen eine zu starke Abkühlung der Isolatoren eintritt. Man hat zwar schon für Elektrofilter Sicherheitsvorrichtungen vorgeschlagen, die bei beginnender Kondensation der im Gas enthaltenen Feuchtigkeit die Hochspannung von der Gasreinigungsanlage abschalten, um so das Entstehen von Kurzschlüssen an den Isolatoren zu verhindern, doch tritt diese Vorrichtung nur dann in Wirksamkeit, wenn die durch die Reinigungskammer selbst hindurchgehenden Gase entsprechend feucht sind. Sind jedoch die Gase genügend trocken, so treten die genannten Vorrichtungen nicht in Tätigkeit, wenn die für die Isolatoren vorgesehene besondere Zusatzheizung versagt. Es können dann also, trotzdem die Gase in der Reinigungskammer genügend trocken sind, sich auf den Isolatoren Kondensationsniederschläge bilden und infolgedessen LTberschläge eintreten. Im folgenden wird nun eine Anordnung gezeigt, durch welche dieser Übelstand beseitigt wird.Heating the insulators of an electrostatic precipitator in electrical gas cleaning systems are usually the isolators in specially heated, from the cleaning chamber housed separate secondary chambers. It is to be achieved by the fact that the Insulators, especially their surface, kept at such a high temperature ensure that no condensation deposits form on the insulators could easily cause undesired current transitions. It has also been suggested To do this, the insulators are heated by heating devices inside the isolators are arranged. It can now happen that this additional heating device for the isolators once failed for some reason and as a result one the insulators cool down too much. One already has for electrostatic precipitators Safety devices proposed that when condensation begins in the Switch off the high voltage of the gas cleaning system, in order to prevent short-circuits on the insulators, but occurs this device is only effective when the cleaning chamber itself passing gases are correspondingly moist. However, if the gases are sufficiently dry, so the devices mentioned do not come into operation if those for the isolators provided special additional heating fails. So it can, anyway, the gases are sufficiently dry in the cleaning chamber that condensation can form on the insulators form and as a result rollover occurs. The following is an arrangement shown by which this deficiency is eliminated.
Gemäß der Erfindung ist für die Isolatoren neben der üblichen Betriebsbeheizung noch eine Reserveheizvorrichtung vorgesehen, die mittels eines Differenzthermometers o. dgl. eingeschaltet wird, sobald die Temperatur der Isolatoren unter einen innerhalb des Regelbereiches der Betriebsheizung liegenden Temperatur festwert sinkt. Durch die Einschaltung dieser Reserv eheizvorrichtung wird dann der Isolator wieder in solchem Maße erhitzt, daß er gegen Kondensationsniederschläge geschützt ist.According to the invention, in addition to the usual operational heating for the insulators still a backup heater is provided, which by means of a differential thermometer o. The like. Is switched on as soon as the temperature of the insulators falls below an inside the temperature set within the control range of the operating heater drops. By Switching on this reserve heating device will then switch the isolator back on heated to such an extent that it is protected against condensation.
Gegebenenfalls kann ferner durch das Differenzthermometer ein Signalgeber in an sich bekannter Weise ausgelöst werden, der den die Anlage Bedienenden auf die Betriebsstörung aufmerksam macht, so daß er diese beseitigen kann, ehe größeres Unheil dadurch entsteht.If necessary, a signal transmitter can also be provided by the differential thermometer be triggered in a manner known per se, the operator of the system on draws attention to the malfunction so that he can eliminate it before a major one Calamity arises as a result.
