Abstract

A device is disclosed for ensuring the reliable operation of heat exchangers with several parallel elements through which flows a liquid for transferring heat between liquid and liquid/gaseous media. In order to vent in a fully automatic manner elements with vertical projections through which flows a liquid, in particular in counterflow-operated hydraulic circuits, the elements through which flows a liquid are designed in such a way that the flow differential pressure is higher by a factor of preferably >/= 1.0 than the sum of the static pressures from the gas/liquid columns generated by the vertical projections in each path of flow, while respecting the process-dependent liquid mass flow.

Description

Die Erfindung betrifft ein Verfahren nach dem Oberbegriff des Patentanspruches 1The invention relates to a method according to the preamble of Claim 1

Stand der TechnikState of the art

Zur zur Entlüftung der flüssigkeitsdurchströmten Bauteile und damit zur betriebssicheren Funktion von Hochleistungs-Wärme­ austauschern, speziell bei Gegenströmern, werden bisher Kreuzstromverschaltungen, als entlüftbare Fluidwege ausge­ führt, verwendet oder es werden nach nach Patent DE 33 25 230 separate Absperrorgane installiert.For venting components and components through which liquid flows thus for the reliable operation of high-performance heat exchangers, especially in countercurrent, have so far Cross-flow circuits, out as ventable fluid paths leads, used or according to patent DE 33 25 230 separate shut-off devices installed.

Alle bekannten Konstruktionen, bei welchen sich die Fluidwege automatisch und damit betriebssicher entlüften, haben den Nachteil, daß reine Gegenstromführungen nur bedingt erreich­ bar sind und dadurch, trotz gleicher Fläche, nur eine geringere Rückwärmzahl erzielbar ist.All known constructions in which the fluid paths bleed automatically and therefore reliably Disadvantage that pure countercurrent guides can only be reached to a limited extent are bar and therefore, despite the same area, only one lower heat recovery is achievable.

Die Ausführungen gemäß Patent DE 33 25 230 und auch EP 0177751 haben den Nachteil, daß separate Absperrorgane zum ggf. notwendigen Entlüften vorgesehen werden müssen, was einen erhöhten Herstellungs-, Montage-, Inbetriebnahme- und Bedienungsaufwand erfordert.The designs according to patent DE 33 25 230 and also EP 0177751 have the disadvantage that separate shut-off devices for any necessary venting must be provided for what an increased manufacturing, assembly, commissioning and Operating effort required.

Aufgabe der ErfindungObject of the invention

Die Aufgabe besteht darin, die Auslegung, Dimensionierung und Betriebsweise der flüssigkeitsdurchströmten Bauteile des Wärmeaustauschers so aufeinander abgestimmt werden, daß eine vollautomatische Entlüftung der flüssiggeführten Bauteile erfolgt und damit eine betriebssichere Funktion gewährleistet ist. Desweiteren soll der Herstellungs-, Montage-, Inbetrieb­ nahme- und Bedienungsaufwand reduziert werden.The task is the design, dimensioning and Operation of the components through which the liquid flows Heat exchanger are matched to each other so that a fully automatic ventilation of the fluid-guided components  takes place and thus ensures a reliable function is. Furthermore, the manufacturing, assembly, commissioning effort and operating expenses can be reduced.

Die Aufgabe wird erfindungsgemäß durch die Anwendung des in den Ansprüchen erwähnte Verfahrens und der Vorrichtung gelöst.The object is achieved by the application of the in the method and the device mentioned in the claims solved.

Um z. B. einen Wärmeaustauscher nach Patent DE 33 25 230 mit 30 Rohrreihen und dementsprechend 30 Höhenversprüngen von jeweils 30 mm betriebssicher zu betreiben, müssen der innere Durchmesser und Länge der flüssigkeitsdurchströmten Bauteile, hier die Rohre, derart ausgelegt werden, daß der Strömungs­ druckverlust größer als 30 Höhenversprünge×30 mmWS entsprechend 900 mmWS ist.To z. B. with a heat exchanger according to patent DE 33 25 230 30 rows of pipes and accordingly 30 height jumps from to operate safely 30 mm each, the inner Diameter and length of the components through which liquid flows, here the pipes are designed so that the flow pressure loss greater than 30 height differences × 30 mmWS corresponding to 900 mmWS.

Durch strömungstechnische Messungen ist ein spezifischer Faktor der flüssigkeitsdurchströmten Bauteile zu ermitteln, bei welchem etwaige Luftpolster, die nicht allein aufgrund des Strömungsdruckverlustes, ausgetrieben werden.Through fluidic measurements is a specific one To determine the factor of the components through which liquid flows, at which any air cushion that is not due solely to the flow pressure loss, are expelled.

Falls aufgrund zu großer Rohrinnendurchmesser diese 900 mmWS nicht erreicht werden, kann z. B. der flüssige Massenstrom zeitweise erhöht werden, so daß durch höhere Fluidgeschwin­ digkeiten höhere Strömungsdifferenzdrücke entstehen. Dazu muß ggf. die Pumpe entsprechend ausgelegt sein oder mit einem Frequenzumformer wird der Pumpenmotor kurzzeitig auf höhere Leistung gefahren oder Teilbereiche des Kreislaufsystems werden mit einer Bypassschaltung kurzgeschlossen, so daß die Pumpenleistung nur auf den zu entlüftenden Wärmeaustauscher wirkt. Vorteilhafterweise enthält die ZLT/GLT einen Steuerungs-Programmteil, welches intermittierend diese Fluidstromerhöhung einschaltet.If this is due to the pipe inside diameter being too large, this 900 mmWS cannot be reached, e.g. B. the liquid mass flow are temporarily increased, so that by higher fluid speeds higher flow differential pressures arise. To do this if necessary, the pump must be designed accordingly or with a The pump motor is temporarily switched to a higher frequency converter Performance driven or parts of the circulatory system are short-circuited with a bypass circuit, so that the Pump output only on the heat exchanger to be vented works. The ZLT / GLT advantageously contains one Control program part, which intermittently this Turns on fluid flow increase.
