Description

Verfahren und Vorrichtung zum Ausspritzen von erhitztem Teer oder erhitzten bituminösen Stoffen Es ist bekannt, Teer oder geschmolzene erhitzte bituminöse Straßenbaustoffe durch einen Dampfstrom. auszuspritzen, wobei der verwendete Dampf in einem besonderen Kessel erzeugt und dazu benutzt wird, zuvor den Teer o. dgl. zu erhitzen.Method and device for spraying out heated tar or Heated bituminous materials It is known to be tar or molten heated bituminous Road building materials by a stream of steam. squirt, using the steam is generated in a special boiler and used to previously the tar o. to heat.

Teer und Bitumen enthalten in geschmolzenem Zustand eine verhältnismäßig große latente Wärme. Es wird also zum Schmelzen und Erhitzen der Baustoffe eine große Dampfmenge benötigt; während zum Ausspritzen selbst eine verhältnismäßig kleine Dampfmenge genügt.When molten, tar and bitumen contain a proportionate amount great latent heat. So it is used to melt and heat the building materials large amount of steam required; while a relatively small one for ejecting itself The amount of steam is sufficient.

Abgesehen von der bezüglich ihres Gewichtes ungünstigen Dampfkesseleinrichtung tritt bei diesen bekannten Vorrichtungen der weitere Nachteil auf, daß die Wärmeausnutzung durch den mehrfachen Wärmedurch-und -übergang - Feuerung, Kesselwand, Wasser, Dampf, Heizschlange, Bitumen -und durch sonstige Wärmeverluste gering ist.Apart from the steam boiler device, which is unfavorable in terms of its weight occurs in these known devices, the further disadvantage that the heat utilization due to the multiple heat transfer and transfer - furnace, boiler wall, water, steam, Heating coil, bitumen and other heat losses are low.

Ein weiterer Nachteil der bekannten Vorrichtungen ist die schwierige Bedienung der Anlage im Betrieb und in der Fortbewegung.Another disadvantage of the known devices is that they are difficult Operation of the system during operation and while moving.

Diese Nachteile sollen nach der Erfindung dadurch beseitigt werden, daß die im erhitzten Teer oder Bitumen enthaltene Wärme zu einem geringen Teil zur Erzeugung gespannten Dampfes verwendet wird. Der Dampf dient zum Ausspritzen des Teers oder Bitumens.According to the invention, these disadvantages are to be eliminated by that the heat contained in the heated tar or bitumen to a small extent Generating pressurized steam is used. The steam is used to eject the Tar or bitumen.

Zu diesem Zwecke ist erfindungsgemäß dicht über dem Boden des zum Kochen bzw. Schmelzen des auszuspritzenden Stoffes dienenden Kessels eine wasserdurchflossene Heizschlange mit einem an diese anschließenden Dampfbehälter angeordnet. Dieser Dampfbehälter steht seinerseits mit einem Sprengbehälter für den erhitzten Stoff in Verbindung, der mittels des Dampfdruckes durch Spritzdüsen o. dgl. ausgespritzt wird.For this purpose, according to the invention, just above the bottom of the for Boiling or melting the substance to be sprayed serving boiler a water-flowed through Heating coil arranged with a steam tank connected to it. This In turn, the steam container has a blasting container for the heated substance in connection, which is sprayed out by means of the steam pressure through spray nozzles or the like will.

Da die zum Ausspritzen erforderliche Temperatur des Baustoffes höher ist als die Verdampfungstemperatur des Wassers, läßt sich gespannter Ausspritzdampf für die gebräuchlichen Baustoffe, die mehr als etwa i io° C Spritztemperatur benötigen, erzeugen.Because the temperature of the building material required for spraying is higher is than the evaporation temperature of the water, can be stressed ejection vapor for common building materials that require a spray temperature of more than about io ° C, produce.

Die Baustoffe mit höherer Schmelztemperatur erfordern eine größere Ausspritzenergie; da jedoch die für das Ausspritzen dieser Stoffe erforderliche Temperatur höher ist als diejenige von Stoffen niederer Schmelztemperatur, steht auch ein höherer Dampfdruck zur Verfügung.The building materials with a higher melting temperature require a higher one Ejection energy; however, because the necessary for the spraying of these substances Temperature is higher than that of substances with a lower melting temperature a higher vapor pressure is also available.

Durch die besondere Anordnung der Rohrschlange am Boden des Schmelzkessels werden die Verkokungsverluste durch örtliche Überhitzungen vermindert. Diese Anordnung ermöglicht daher die nahezu restlose Verarbeitung des Kesselinhaltes.Due to the special arrangement of the pipe coil at the bottom of the melting kettle the coking losses due to local overheating are reduced. This arrangement therefore enables the boiler contents to be processed almost completely.
