Description

Verfahren zur Reinigung brennbaren Staub enthaltender Gase hoher Temperatur Die Verwertung brennbaren Staub enthaltender Gase mit hohen Temperaturen, wie sie in den verschiedenen Industrien vorkommen, z. B. bei den Abgasen der Zementdrehrohröfen, bietet Schwierigkeiten. Es ist schon vorgeschlagen, die Gase erst zu kühlen und dann elektrisch zu reinigen. Dabei ist aber der Nachteil vorhanden, daß sich die Kühlvorrichtung schnell mit Staub zusetzt und so unwirksam wird. Bei Kesselheizungen ist es üblich, von Zeit zu Zeit eine Reinigung vorzunehmen, z. B. durch Abblasen. Dies Verfahren würde sich aber in Verbindung mit einer elektrischen Gasreinigung nicht eignen, -weil die elektrische Kammer dabei stoßweise beansprucht und dadurch ungenügend ausgenutzt würde.Process for cleaning high temperature gases containing combustible dust The recovery of combustible dust-containing gases with high temperatures, such as them occur in various industries, e.g. B. in the exhaust gases of the cement rotary kilns, offers difficulties. It has already been suggested to cool the gases first and then then to be cleaned electrically. But there is the disadvantage that the Cooling device quickly clogs with dust and thus becomes ineffective. With boiler heating it is common to do some cleaning from time to time, e.g. B. by blowing off. This process would, however, be used in conjunction with electrical gas cleaning not suitable, -because the electrical chamber is stressed intermittently and thereby would be insufficiently exploited.

Zur Behebung dieses Mangels wird erfindungsgemäß das heiße, brennbaren Staub enthaltende Gas zuerst in eine Kesselanlage geschickt, wo die Wärme nutzbringend verwertet wird und eine an sich bekannte wandernde Abblasevorrichtung die Einzelteile der Kessel nacheinander reinigt, so daß Staubgehalt und Gasmenge konstant bleiben und in dem dahinter angeordneten elektrischen Gasreiniger beliebiger Bauart eine gleichmäßige Beanspruchung eintritt. Man kann weiterhin den niedergeschlagenen Staub, wenn er noch unverbrannte Teile enthalten sollte, in die Brennzone, das ist in die Erzeugungsstelle des Gases, zurückführen, um eine restlose Verbrennung unverbrannter Teile herbeizuführen. Zweckmäßig verwendet man hierzu die pneumatische Förderung, wodurch eine innige Vermischung des Staubes mit neuer Verbrennungsluft eintritt.- Gleichzeitig werden dadurch Transportvorrichtungen gespart. Nötigenfalls kann man dabei neuen Kohlenstaub-oder flüssigen Brennstoff zugeben, um eine genügend hohe Verbrennungstemperatur zu erreichen.In order to remedy this deficiency, the hot, combustible one is used according to the invention Gas containing dust is first sent to a boiler plant, where the heat is beneficial is recovered and a known wandering blow-off device the items the boiler cleans one after the other so that the dust content and amount of gas remain constant and in the electrical gas cleaner of any type arranged behind it one uniform stress occurs. One can still keep the downcast dust, if it should still contain unburned parts, in the burning zone, that is in the Production point of the gas, return to a complete combustion of unburned Bring about parts. Pneumatic conveying is expediently used for this purpose, whereby an intimate mixing of the dust with new combustion air occurs. At the same time, transport devices are saved as a result. If necessary, you can while adding new pulverized coal or liquid fuel to a sufficiently high level To reach combustion temperature.
