Description
Technisches GebietTechnical area
Wärmetauscher zur Übertragung von thermischer Energie eines Luft- oder Gasstroms auf einen Flüssigkeitskreislauf sind seit Langem bekannt. Eine bevorzugte Bauart besteht gemäß
Stand der Technik, Mängel, ProblemeState of the art, deficiencies, problems
Fällt durch Abkühlung der Luft beim Passieren des Wärmetauschers Kondensat an, so läuft es an den Lamellen und den vertikalen Rahmenteilen
Ausführungsbeispiel, BeschreibungEmbodiment, description
Gegenstand der vorliegenden Erfindung ist ein einfaches System zur Vermeidung von umweltschädlichem Fluideintrag in die Umwelt, ohne bewegliche Teile und ohne dem Einsatz von Energie zum Betrieb von Antrieben, Steuerung und Sensorik, wobei das beim Betrieb anfallende Kondensat in's Freie oder in eine Abwasserleitung geleitet wird.The subject of the present invention is a simple system for avoiding environmentally harmful fluid entry into the environment, without moving parts and without the use of energy for the operation of drives, controls and sensors, whereby the condensate occurring during operation is discharged into the open or into a sewer.
Vorgeschlagen wird System mit drei Wannen.
Die beiden vertikalen Rahmenteile
Basis für die Funktion des Systems ist, dass die geraden horizontalen Rohrabschnitte
- - Die
Rohrverbindungen 15 an denUmlenkungen 7 , die die Umlenkungen mit den geraden Rohrteilen verbinden, werden typischereweise durch Schweißen, Hartlöten oder durch andere Fügeverfahren realisiert.Rohrverbindungen 15 undUmlenkungen 7 stellen Schwachstellen imRohrbündel 2 dar, welche eine vielfach höhere Ausfall- und damit Leckagewahrscheinlichkeit als die geradenhorizontalen Rohrabschnitte 6 haben. - - Die
Umlenkungen 7 des Rohrbündels links und rechts der Rahmenteile werden typischerweise und erfindungsgemäß durch Biegen hergestellt. Dadurch wird das Rohrmaterial gestreckt und gestaucht, was einer Vorbelastung des Materials in diesem Bereich darstellt und damit die Ausfall- und Leckagewahrscheinlichkeit deutlich erhöht gegenüber den geradenhorizontalen Rohrabschnitten 6 . - - Es werden
Berstelemente 16 links und rechts dervertikalen Rahmenteile 4 ,5 in das Rohrbündel eingebaut, die bei einem Druck versagen, der mit einem angemessenen Sicherheitsfaktor niedriger ist als der Berstdruck des Rohrbündels und insbesondere der geradenhorizontalen Rohrabschnitte 6 . - - Für die geraden
horizontalen Rohrabschnitte 6 werden besondere qualitätssichernde Maßnahmen ergriffen, um sicherzustellen, dass diese während der gesamten Betriebszeit des Wärmetauschers keine Leckage aufweisen werden und die Leckagewahrscheinlichkeit relativ zu den Teilen desRohrbündels 2 , die links des linkenvertikalen Rahmenteils 4 und rechts des rechtenvertikalen Rahmenteils 5 liegen, um Größenordnungen senkt. Als qualitätssichernden Maßnahmen werden erfindungsgemäß vorgeschlagen:- o Wandstärkenprüfung, einmalig beim Bau des Wärmetauschers oder regelmäßig während des Betriebs
- o Zerstörende Druckprüfung an Rohrproben aus der gleichen Charge wie die verbauten Rohre in den geraden
horizontalen Rohrabschnitten 6 zur Feststellung, ob der tatsächliche Berstdruck ausreichend hoch ist - ◯ Optische Inspektion zur Festellung, dass die Rohre keine Beschädigungen oder Unregelmäßigkeiten an der Oberfläche, sowohl innen und/oder auch aussen aufweisen.
- - The pipe connections
15th at the deflections7th that connect the deflections with the straight pipe parts are typically realized by welding, brazing or other joining processes. Pipe connections15th and diversions7th create weak points in thetube bundle 2 which has a much higher probability of failure and thus leakage than the straight horizontal pipe sections6th to have. - - The diversions
7th of the tube bundle on the left and right of the frame parts are typically and according to the invention produced by bending. As a result, the pipe material is stretched and compressed, which represents a pre-load on the material in this area and thus significantly increases the probability of failure and leakage compared to the straight horizontal pipe sections6th . - - There will be bursting
elements 16 left and right of the vertical frame parts4th ,5 incorporated in the tube bundle which will fail at a pressure which is lower with a reasonable safety factor than the burst pressure of the tube bundle and in particular of the straight horizontal pipe sections6th . - - For the straight horizontal pipe sections
6th special quality assurance measures are taken to ensure that these will not leak during the entire operating time of the heat exchanger and that the leakage probability is relative to the parts of thetube bundle 2 , the left of the left vertical frame part4th and to the right of the rightvertical frame part 5 lie down by orders of magnitude. According to the invention, the following are proposed as quality assurance measures:- o Wall thickness test, once during the construction of the heat exchanger or regularly during operation
- o Destructive pressure test on pipe samples from the same batch as the pipes installed in the straight horizontal pipe sections
6th to determine whether the actual burst pressure is sufficiently high - ◯ Optical inspection to determine that the pipes have no damage or irregularities on the surface, either inside and / or outside.
