Abstract

An installation for drying and cleaning the windings of transformers, solenoids, etc., using kerosene, has a set of storage tanks (2) connected to a heat exchanger (9) which receives the contaminated kerosene, or connected directly to a main evaporating and preheating tank (1). After evaporation, the vapourised part then passes to a heated separating tank (4). This is followed by a main condenser (21) where the product is cooled to a warm liquid, filtered and passed to an evaporator (24). A pump (25) then returns the liquid to the storage tanks (2). The hot condensate in the bottom of the separator tank (4) is returned to a separator (6). The heating tank (1) can be fitted with level monitors (3) to compensate for evaporation, and has a valve (8) for discharge of contaminated liquid to the heat exchanger (9).

Description

Kreislauf eines organischen Wärmeträgers Circuit of an organic heat transfer medium

in Trocken-und/oder Reinigungsanlagen. in drying and / or cleaning systems.

Lie Erfindung befaßt sich nit der, einen stehenden Umlaufverdampfer zugeführten Wärmeträgermenge, deren Brüden einem Trockenschrank zugeführt werden und dessen kondensat allein vom Boden des Trockenschrankes direkt oder über einen Abscheider in den stehenden Umlaufverdampfer zurückgeführt wird. Der sich in diesem Verdampfer ansammelnde heiße verschmutzte Sumpf wird zur Vorheizung des kalten frischen Wärmeträgers in einem Wärmetauscher ausgenutzt.The invention is concerned with the, a standing circulation evaporator supplied amount of heat transfer medium, the vapors of which are fed to a drying cabinet and its condensate alone from the bottom of the drying cabinet directly or via a Separator is returned to the standing circulation evaporator. Which is in this Evaporator accumulating hot polluted sump is used to preheat the cold fresh Exploited heat carrier in a heat exchanger.

Der Vorteil dieser Anordnung nacn der Hauptpatentanmeldung 2 26 o5 77 besteht aarin, daß die Anlage mit einer guten Energiewirtschftlichen Ausnutzung und damit auch einer verhältnismäßig geringen wärmeträgermenge arbeitet.The advantage of this arrangement according to the main patent application 2 26 o5 77 insists that the plant has a good energy efficiency and thus also a relatively small amount of heat transfer medium works.

In der Weiterentwicklung derartiger Anlagen hat sich nun herausgestellt, daß eine noch größere Einsparung der Energiemenge gepaart mit einer wesentlichen Verringerung der Wärmeträgermenge erreichbar ist, wenn der Entzug aus dem Trockenschrank in interschiedlichen Teilströmen erfolgt.In the further development of such systems it has now been found that an even greater saving in the amount of energy coupled with a substantial Reducing the amount of heat transfer medium can be achieved if the withdrawal from the drying cabinet takes place in different substreams.

Gemäß dieser Zusatzerfindung ist der Kreislauf eines organischen Wärmeträgers in Trocken- und/oder Reinigungsanlagen aadurch geennzeicnnet, daß die sicn in Trockenschrank mit unterschiedlichen Temperaturen befindlichen Brüden und Kondensate einerseits als Brüden-Teilstrom über die im oberen Teil des Trockenschrankes angeordnete Rohrführung durch des Hauptkondensator mit Kühlvorrichtung und einen Abschneider von einer Pumpe nach ausreichender Abkühlung direkt dem Lagerbehälter als sauberer Wärmeträger zugeführt wird, während das sehr neige aber stark verschmutzte, a.n Boden des Trockenschrankes angesammelte Kondensat als zweiter Teilstrom allein über den gut isolierten oder beheizten Abschneider mittels Pumpe unmittelbar in den stehenden Umlauf- Verdapfer geführt wird. Mit besonderem Vorteil wird durch diese Teilströme eine kontinuierliche Gesamttrocken-oder Reinigungszeit bei Einsparung erheblicher Vorratsmengen des äußerst explosivem Wärmeträgers erreicht.According to this additional invention, the cycle is an organic heat carrier In drying and / or cleaning systems, it is indicated that they are in a drying cabinet with different temperatures located vapors and condensates on the one hand as partial vapor flow over the one in the upper part of the drying cabinet arranged pipe routing through the main condenser with cooling device and a Cutter from a pump directly to the storage container after cooling down sufficiently is supplied as a clean heat transfer medium, while the very tending but heavily soiled, a.n the bottom of the drying cabinet, accumulated condensate as a second partial flow alone directly into the well-insulated or heated cutter by means of a pump the standing circulation evaporator is performed. With particular advantage is through these partial flows provide a continuous total drying or cleaning time with savings significant storage quantities of the extremely explosive heat carrier reached.

aus den Vorratsbehältern 2, die den hochexplosiven Wärmeträger, beispielsweise kerosin enthalten und die in besonderen exlosionssicneren Gebäuden angeordnet sein müssen, wird der Wärmeträger dem stehenden Umlauf-Verdampfer 1 zugeführt, dessen mini-maxi-Schalter 3 die eingegebene Menge begrenzen. Diesem stehenden Umlauf-Verdampfer 1 ist ein Wärmetauscher 9 vorgeschaltet, der erst kurze Zeit nach den Durchlauf der ersten neißen Wärmeträgermassen durch Ablassung des schmutzigen Kondensates aus den stehenden Umlaufverdampfer 1 über das Ventil 8 in Tätigkeit ist. Die vom Umlaufverdampfer 1 in den Trockenschrank 4 geführten Bräden umspülen den noch Kalten, zu trocknenden und/oder zu reinigenden Gegenstand unter gleichzeitiger Aufheizung desselben und Kondensieren durch den Temperaturaofall. Die Vakuumpumpe 13 entzieht bereits den eingegebenen Früden die annaftenden vorhanden und erreichbaren Wasseranteile. Die nun im Trockenschrank befindlichen Brüden werden über die Rohrführung 20 dem Hauptkondensator 21, der mit einer Kühlvorrichtung 22 ausgestattet ist zugeführt und weitgehend kondensiert in dem Abscheider 24 gereinigt und über die Pumpe 25 direkt in die Lagerbehälter ausreichend gekühlt als sauberer Wärmeträger zurückgepumpt.from the storage containers 2, which contain the highly explosive heat transfer medium, for example contain kerosene and are arranged in special explosion-proof buildings must, the heat transfer medium is fed to the standing circulation evaporator 1, whose mini-maxi switch 3 limit the amount entered. This standing circulation evaporator 1, a heat exchanger 9 is connected upstream, which only shortly after the passage the first neissen heat transfer media by draining the dirty condensate from the standing circulation evaporator 1 via the valve 8 is in operation. The ones from Circulation evaporator 1 in the drying cabinet 4 washed around the still cold, Object to be dried and / or cleaned with simultaneous heating the same and condensation due to the temperature aof case. The vacuum pump 13 withdraws the existing and achievable proportions of water that have already been entered. The vapors now in the drying cabinet are transferred to the Pipe guide 20 is supplied to the main condenser 21, which is equipped with a cooling device 22 and largely condensed in the separator 24 and cleaned via the pump 25 Pumped back directly into the storage container, sufficiently cooled, as a clean heat transfer medium.

Das verschmutzte Kondensat 5 im Trockenschrank 4 wird als zweiter Teilstrom aus kürzestem Weg lediglich in dem gut isolierten und/oder beheizten Abscheider 6 gereinigt und als heißer Wärmeträger direkt in den stehenden Umlauf-Verdampfer 1 mittels der Pumpe 18 zurückgebracht.The dirty condensate 5 in the drying cabinet 4 is the second Partial flow from the shortest route only in the well-insulated and / or heated separator 6 cleaned and used as a hot heat transfer medium directly in the standing circulation evaporator 1 brought back by means of the pump 18.

Der geringe Temperaturunterschied, der im Umlaufverdampfer zun Aufheizen bis zun Ernalt von Dampfbräden benötigt wird, bedingt Keine Unterbrechung des gesamten Trocknungs- oder Reinigungsvorganges und damit auch keine Abkühlung des zu trocknenden oder zu reinigenden Gerätes im TrocKenschrank 4. Die aus dem stehenden Umlaufverdampfer 1 abzuführenden, angesammelten verschmutzen heißen Kondensatabalgerungen, die über das Ventil 8 dem Wärmetauscher 9 zugeführt werde, dienen nun der Vorwärmung des neu zuzuführenden Wärmeträgers, der von dem mini-maxi-Schalter 3 angefordert und begrenzt wird. Die aus den Abseneiaern 6, 24 und dem Wärmetauscher 9 zu entfernenden schmutzigen Abfälle werden einer Filteranlage zugeführt aus der das ausgefilterte Kerosin einer nochmaligen Reinigung unterzogen werden kann.The small temperature difference that leads to heating in the circulation evaporator until steam is needed at first, no interruption of the whole process Drying or cleaning process and thus no cooling of the one to be dried or the device to be cleaned in the drying cabinet 4. The from the standing circulation evaporator 1 to be discharged, accumulated dirty condensate drainage, which is about the valve 8 is fed to the heat exchanger 9 are now used to preheat the newly supplied heat transfer medium, which is requested by the mini-maxi switch 3 and is limited. Those to be removed from the Abseneiaern 6, 24 and the heat exchanger 9 dirty waste is fed to a filter system from which the filtered waste Kerosene can be cleaned again.
