Description

Vereinigung eines Hochofenprozesses zur Phosphorsäuregewinnung mit der Gewinnung hochwertiger Generatorgase. Es besteht ein Verfahren zur gleichzeitigen Gewinnung von Phosphorsäure und hochwertigen Generatorgasen, bei dem der mit Phosphoriten, Silikaten und Kohle beschickte Hochofen als Gasgenerator wirkt und durch Einblasen von heißer Luft betrieben wird. Es bilden sich hierbei im wesentlichen Kohlenoxyd und Stickstoff neben geringen Mengen Kohlensäure usw.Association of a blast furnace process for the production of phosphoric acid with the production of high-quality generator gases. There is a method for simultaneous Production of phosphoric acid and high-quality generator gases, in which the one with phosphorites, Silicates and coal-fed blast furnace acts as a gas generator and by blowing it in operated by hot air. In the process, carbon dioxide is essentially formed and nitrogen in addition to small amounts of carbonic acid, etc.

Gemäß der Erfindung soll der Hochofen zeitweise anstatt mit Luft mit erhitztem Wasserdampf zwecks Gewinnung von Wassergas betrieben werden, und es wird, wenn die Temperatur des Ofens heruntergegangen ist, das Zuleiten von überhitztem Wasserdampf abgestellt und die Erhöhung der Temperatur durch Einblasen von heißer Luft bewirkt. Man erhält auf diese Weise neben Generatorgas in dem Zeitintervall, wo der Generator mit überhitztem Wasserdampf betrieben wird, Wassergas, das im wesentlichen aus Wasserstoff nebst geringen Mengen von Kohlenoxyd besteht. Man kann aber auch den Hochofen gleichzeitig mit überhitztem Wasserdampf und heißer Luft betreiben, wodurch man neben der Phosphorsäure Mischgas, also ein an Wasserstoff reiches Kohlenoxydgas, erhält. Selbstverständlich muß man die Temperatur, bei der die Reduktion der in der Charge enthaltenen gebundenen Phosphorsäure zu Phosphor stattfindet, im Hochofen regeln und danach das Verhältnis von Wasserdampf und Luft einrichten.According to the invention, the blast furnace should temporarily instead of air heated steam for the purpose of obtaining water gas, and it is, when the temperature of the furnace has gone down, adding superheated Turning off steam and increasing the temperature by blowing hotter Air causes. In this way, in addition to generator gas in the time interval where the generator is operated with superheated steam, water gas that is essentially consists of hydrogen and small amounts of carbon monoxide. But you can too operate the furnace with superheated steam and hot air at the same time, whereby, in addition to the phosphoric acid, mixed gas, i.e. a carbon oxide gas rich in hydrogen, receives. Of course, the temperature at which the reduction of the in the charge contained bound phosphoric acid to phosphorus takes place in the blast furnace regulate and then set up the ratio of water vapor and air.
