Description

Einsatzkörper für Rohre in Dampfke . soeln und anderen Wärmeaustauschern Um die Gase in Rohren von Dampfkesseln oder anderen Wärmeaustauschern in Drall zu versetzen, sind Einsatzkörper für dieseRohre bekannt, welche aus mehreren Ablenkflächen bestehen. Die Drallwirkung kann durch Einbau mehrerer Drallkörper nebeneinander erhöht werden, indem mehrere Drallströme hi demselben Rohr-erzeugt werden, welche sich, jeder um die eigene Achse sich drehand, mit entgegengesetzter Drehrichtung parallel eueinander fortbewegen und nicht durch Zwischenwände voneinander getrennt sind. Hierbei müssen -unter Umständen mehrere Drallkörper hintereinander angeordnet werden, da sich die Energie der Drallbewegung verhältnismäßig schnell aufzehrt.Insert body for pipes in steam . Soels and other heat exchangers In order to make the gases in the tubes of steam boilers or other heat exchangers swirl, insert bodies for these tubes are known which consist of several deflecting surfaces. The swirl effect can be increased by installing several swirl bodies next to one another by generating several swirl flows in the same pipe, which each rotate around their own axis, move parallel to one another in opposite directions of rotation and are not separated from one another by partition walls. Under certain circumstances, several swirl bodies must be arranged one behind the other, since the energy of the swirl movement is consumed relatively quickly.

Um diesen Nachteil zu vermeiden, wira der Einsatzkörper nach vorliegender Erfindung so ausgebildet, daß die Einzeldrallströme die gleiche Drehrichtung haben und einen gemeinsamen Drallstrom bilded. Durch diese doppelte Drallbewegung werden die inneren, in der Rohrmitte noch nicht abgekühlten Rauchgase ständig nach außen getrieben und dabei zwangsläufig durch den gemeinsamen Drallstrom an dem Rohrmantel entlang geführt. Der Rohrmantel wird infolgedessen a-uf der ganzen Rohrlänge und in jedem Quers#Imitt des Rohres gleichmäßig erwärmt, so daß keine Materialspannungen und ungleiche Ausdehnungen im Rohrmantel entstehen kÖnnen.In order to avoid this disadvantage, the insert body according to the present invention is used Invention designed so that the individual swirl currents have the same direction of rotation and forms a common swirl flow. Through this double twisting movement the inner flue gases, which have not yet cooled down in the middle of the pipe, are constantly escaping to the outside driven and inevitably by the common swirl flow on the pipe jacket led along. The pipe jacket is consequently a-uf the entire pipe length and Uniformly heated in every cross # Imitt of the tube, so that no material stresses and uneven expansions in the pipe jacket can occur.

Im Ausführungsbeispiel nach beiliegender Zeichnung, die in Abb. i einen Querschnitt, in Abb. 2 einen LäAgsschnitt durch ein Flammrohr darstellt, besteht der Einsatzkörpera aus vier Lenkflächen b, welche schaufelförmig ausgebildet sind. Die durchziehenden Rauchgase werden beim Auftreffen auf die Schaufelfläch,en in Drall versetzt, so daß viereinzelne gleichgerichtete Drallströme, entstehen. Da die Schaufelflächen außerdem schräg zur Strömungsrichtung der Gase im R.bhre stehen, werden die EinzeldräUströme aus ihrer Achsenrichtung so abgelenkt, daß sie ihrerseits einen gemeinsamen Drallstrom mit ebenfalls der gleichen Drehrichtung bilden.In the embodiment according to the accompanying drawing, which is shown in Fig. I a cross section, in Fig. 2 shows a longitudinal section through a flame tube, consists the insert body a from four steering surfaces b, which are designed in the shape of a shovel. When they hit the blade surface, the smoke gases passing through are in Swirl offset, so that four individual rectified swirl currents arise. There the blade surfaces are also inclined to the direction of flow of the gases in the R.bhre, the individual flow currents are deflected from their axial direction so that they in turn form a common swirl flow also with the same direction of rotation.

Durch die Zusammenfassung der Einzeldrallströme wird der gemeinsame Drallstrom so stark, daß >er' auf einer verhältnismäßig großen Rohrlänge wirkt, chne daß mehrere Einsatzkörper hintereinander angeordnet zu werden brauchen.By combining the individual swirl currents, the common The swirl flow is so strong that it acts over a relatively large length of the pipe, Chne that several insert bodies need to be arranged one behind the other.
