Description

Heißdampf -Temperaturregler Es sind Dampicemperaturregler oder Dampfkühler bekannt, die mit einem oder mehreren Rohren verseifen sind, durch die der zu kühlende Dampf strömt und in die durch Düsen fein zerstäubtes Kühlwasser in Richtung der Dampfströmung eingespritzt wird. Die Verdampferrohre sind dabei von dem zu kühlenden Heißdampf umgeben. Bei derartigen Dampfkühlern läßt es sich nun bei sehr schwierigen Betriebsverhältnissen oft nicht vermeiden, daß ein Teil Einspritzwasser unverdampft bleibt, da sich der Dampf nicht genügend mit dem Einspritzwasser mischen kann. Die Erfindung soll diesen Mangel beseitigen. Dies geschieht dadurch, daB in den Verdampferrohren, die in bekannter Weise am Eintrittsende düsenförmig ausgebildet sind, hinter den düsenförmigen Stücken besondere öffnungen vorgesehen werden, durch die dem in den Verdampferrohren bereits strömenden Dampfwassergemisch nach und nach in verschiedenen Mengen unterteilt weiterer überhitzter Dampf zug°führt wird. Durch diese Anordnung wird das Einspritzwasser mit dem zu kühlenden Dampf gut durchmischt, wodurch eine restlose Verdampfung des Einspritzwassers stattfinden soll.Superheated steam temperature controller These are steam temperature controllers or steam coolers known, which are saponified with one or more pipes through which the to be cooled Steam flows and into the cooling water finely atomized by nozzles in the direction of the Steam flow is injected. The evaporator tubes are from the one to be cooled Surrounded by superheated steam. With such steam coolers it can now be very difficult Operating conditions often do not prevent part of the injection water from evaporating remains because the steam cannot mix sufficiently with the injection water. the Invention is intended to remedy this deficiency. This happens because in the evaporator tubes, which are nozzle-shaped in a known manner at the inlet end, behind the nozzle-shaped pieces special openings are provided through which the in the Evaporator tubes already flowing steam water mixture gradually in different Subdivided quantities of further superheated steam is added. Through this arrangement the injection water is mixed well with the steam to be cooled, creating a complete evaporation of the injection water should take place.

Die Zeichnung stellt zwei Bauarten gemäß der Erfindung dar. Die Abb. i und 2 zeigen je einen Längsschnitt der beiden Bauarten, die Abb. 3 einen Querschnitt durch beide Vorrichtungen. Der zu kühlende Heißdampf strömt in Pfeilrichtung a in den Dampftemperaturregler. Durch die Düsenleitung b wird das Einspritzwasser durch Zerstäuberdüsen c den Verdampferrohren e, und zwar den an den Eintrittsenden der Verdampferrohre befindlichen düsenförmigen Teilen, zugeführt. Gemäß der Erfindung wird. bei der Bauart nach Abb. r durch die hinter den düsenförmigen Teilen der Verdampferrohre befindlichen Schlitze f dem -bereits in den Verd "i.Zebren strömenden D#Linpfwassergem 1 isg, # > Nr eiterer HeiBdäiüpf zugeführt. In der Bauart nach Abb. 2 sind die Verdämpferrohre in Rohrabschnitte h unterteilt und in Abständen voneinander angeordnet, go daß dem Dampfwassergemiech, weiterer Heißdampf durch die entstehenceri Ringquerschnitte beigemischt werden --känn. Der durch die Schlitze f bzw. die R-ingquerschnitte zwischen den Rohrabschnitten ji-eintretende Heißdampf mischt sich mit -deni bereits in den Verdampferrohren strömenden Dampfwassergemisch und bewiest damit eine restlose Verdampfung des : ngeipritzten Wassers. Das durch plötzliche Leistungsschwankungen bei Sättigung des Dampfes etwa auftretende Übersc@ ßwasser vgxd durch den EntwässerungsstUtzen d ätrgeführt. Damit der Dampf vollkommen fand .,trocken und gleichmäßig den Dampftempera£ürregler verläßt, sind hinrter den Verdameferrohren in bekannter Weise Abscheidevörrichtungen in Form von Abscheide-,vänden 9- 2'-angeordnet, die das Mitreißen von Wasser verhindern sollen.The drawing shows two types according to the invention. FIGS. 1 and 2 each show a longitudinal section of the two types, and FIG. 3 shows a cross section through both devices. The superheated steam to be cooled flows in the direction of arrow a into the steam temperature controller. The injection water is fed through the nozzle line b through atomizing nozzles c to the evaporator tubes e, specifically to the nozzle-shaped parts located at the inlet ends of the evaporator tubes. According to the invention. In the design according to Fig. r, through the slots located behind the nozzle-shaped parts of the evaporator tubes, the D # Linpfwassergem 1 isg, # > Nr The evaporator pipes are divided into pipe sections h and arranged at a distance from one another, so that further superheated steam can be added to the steam-water mixture through the resulting ring cross-sections. The superheated steam entering through the slots f or the ring cross-sections between the pipe sections ji is mixed with it - the steam-water mixture already flowing in the evaporator tubes and thus proves complete evaporation of the splashed water. The excess water, which may occur due to sudden fluctuations in output when the steam is saturated, is passed through the drainage supports. So that the steam found perfect, dry and even If the steam temperature controller leaves, the evaporator pipes are behind n Abscheidevörrichtungen in a known manner in the form of separation, walls 9-2 'arranged to prevent the entrainment of water.
