Description
Vorrichtung zur Konzentration von Schwefelsäure Der vorliegende Eindampfapparat, bei dem in bekannter Weise heiße Gase zwecks Verdampfung des Wassers der Säure auf diese zur Einwirkung gebracht werden, ist, wie aus folgendem ersichtlich, eingerichtet: Die zu konzentrierende Säure tritt durch die Öffnung A (s. Abbildung) in die von einer Anzahl Heizröhren Bin vertikaler Richtung durchzogene Abteilung C ein, füllt diese wie auch das am Fuße mit Durchlässen D - versehene Steigrohr E vollständig aus und fließt aus diesem in die Abteilung F. In letzterer Abteilung bildet sich eine durch die aus dem Boden einheitlich hervorragenden Heizrohrenden B1 bedingte Säureschicht, von deren Oberfläche ab ein gleichmäßiger Überlauf in sämtliche Heizröhren erfolgt. Aus diesen Röhren gelangt die Säure in die Abteilung G, bildet hier ebenfalls eine Schicht, von welcher die überschüssige Menge durch die Öffnung H in ein Kühlgefäß abgegeben wird.Device for the concentration of sulfuric acid The present evaporator, in which in a known manner hot gases for the purpose of evaporation of the water of the acid these are brought into effect, is set up, as can be seen from the following: The acid to be concentrated enters the from opening A (see illustration) a number of heating tubes this as well as the riser pipe E, which is provided with passages D at the foot, is complete from and flows out of this into department F. In the latter department forms one caused by the heating pipe ends B1 protruding uniformly from the ground Acid layer, from the surface of which an even overflow into all heating tubes he follows. The acid reaches compartment G from these tubes, where it also forms a layer from which the excess amount through the opening H into a cooling vessel is delivered.
Die Heizgase strömen durch den Kanal J in die Abteilung G, wo sie sich, auf der Säureoberfläche ausbreitend, in die Heizröhren verteilen, in welchen sie mit der Säure in innige Berührung geraten. Die Heizgase sättigen sich mit Wasserdampf und werden bei ihrem Übertritt aus den Heizröhren in die Abteilung F mittels der Kalotten K nochmals in enge Berührung mit der Säure gebracht. Endlich entweichen die Gase, das aus der Säure ausgetriebene Wasser mit sich führend, durch die Saugleitung L nach einem Kondensator.The heating gases flow through channel J into department G, where they spreading on the surface of the acid in the heating tubes, in which they come into intimate contact with the acid. The heating gases are saturated with water vapor and when they pass from the heating pipes into compartment F, they are Calottes K brought into close contact with the acid again. Escape at last the gases, carrying the water expelled from the acid, through the suction line L after a capacitor.
Da bei dem Prozeß die in der Abteilung C befindliche Säure bereits stark vorgewärmt wird, so könnten bei etwaiger Verschlammung der Durchlässe D Druckspannungen entstehen, die aber durch die von der Abteilung C in die Abteilung F führenden Entlastungsstutzen M vermieden werden.Since in the process the acid in department C is already present If the passages D are heavily preheated, compressive stresses could occur if the passages D become silted up which arise, however, through the relief nozzles leading from department C to department F. M to be avoided.
Die Vorteile des Apparates lassen sich in besonders günstigen Leistungsmöglichkeiten bei verhältnismäßig sehr geringen Anschaffungs-und Betriebskosten erblicken.The advantages of the apparatus can be seen in particularly favorable performance options behold at relatively very low acquisition and operating costs.
