Abstract
Description
Allgemeines: Die mit dem herkömmlichen Perchloräthylen oder ähnlich giftigen Plotten arbeitenden Metallentfettungsanlagen leiden unter dem Umstand, daß während der Trocknungsperiode bzw. während des Einbringens und des Ausbringens der Ware in bzw. aus der Anlage, mit giftigen Gasen angereicherte Luft in die Atmosphäre entweicht, was im Widerspruch mit dem Umweltschutzanspruch steht. Auch wenn die besagten Äbluftga se einen Rückgewinnungsapparat passieren, treten immer noch Restgase in die Atmosphäre iiber, abgesehen davon, daß die Rückgewinnungsanlage erhebliches Geld und Unterhalt kostet, was die Wirtschaftlichkeit der Anlage in Prage stellen kann.General: Those with conventional perchlorethylene or similar metal degreasing systems working with toxic plots suffer from the fact that that during the drying period or during the introduction and the application the goods in or out of the system, air enriched with toxic gases into the atmosphere escapes, which is in contradiction to environmental protection requirements. Even if the Said exhaust gases pass through a recovery apparatus, residual gases still occur into the atmosphere, apart from the fact that the recovery plant does considerable Money and maintenance costs, which put the profitability of the plant in Prague can.
Aus diesem Grunde wurde eine Anlage erfunden, die mit den Sicher heitsflotten CCL3F bzw. C2F3CL3 arbeitet, und deren Wirtschcsft lichkeit, gegenüber ähnlichen Anlagen, eine weitaus bessere ist.For this reason, a system was invented with the security fleets CCL3F or C2F3CL3 works, and their economic efficiency, compared to similar ones Plants, which is a far better one.
Die nachfolgend umschriebene Anlage zur Entfettung und Reinigung von Stahl und Metallen, deren Späne oder auch Kleinteilen, Kunststoffen usw., besteht aus dem Entfettungs- bzw. Reinigungsappa rat 12 und den dazugehörigen Zusatzapparaten Destillator 5, dem Gaskondensator 6, den Gaskühlern und--Erhitzern 7 und 8, dem Art eit stank 1 und dem Kälteverdichtersatz 2, der in der herkömmlichen Weise als Wärmepumpe ausgebildet ist, wobei das für den Entfettungs- und Reinigungsprozeß notwendige Kalt- und heißwasser von der Wärmepumpe erzeugt wird. Durch diese Auslegung ist es möglich, sowohl eine Destiliation als auch eine Kondensation der Arbeitsflotte dürchzuführen, da die Siede- bzw. Kondensationstemperaturen der CCL3F-, bzw. C2F3CL3-?lotten unterhalb der erreichbaren Heißwassertemperatur bzw. oberhalb der erreichbaren Kaltwassertemperatur von + 55 Grad C bzw. + 4 Grad C liegen. Die Siedetemueratur der Plotte CCL3P liegt bei + 23,7 Grad C und die der Flotte C2F3CL3 bei + 47,6 Grad C.The system described below for degreasing and cleaning of Steel and metals, their chips or small parts, plastics, etc., is made from the degreasing or cleaning device 12 and the associated additional devices Distillator 5, the gas condenser 6, the gas coolers and heaters 7 and 8, the Art eit stank 1 and the refrigeration compressor set 2, which in the conventional way as Heat pump is designed, which for the degreasing and cleaning process the necessary cold and hot water is generated by the heat pump. Through this interpretation it is possible to have both a distillation and a condensation of the working liquor due to the fact that the boiling or condensation temperatures of the CCL3F- or C2F3CL3-? lotten below the achievable hot water temperature or above the achievable cold water temperature from + 55 degrees C or + 4 degrees C. The boiling temperature of the CCL3P plotter is included + 23.7 degrees C and that of the fleet C2F3CL3 at + 47.6 degrees C.
Die hierbei auftretenden Leistungsziffern erbringen eine Nutzleistung von 3500 Kcalorien//KW auf der Warmseite und 2500 Kcal/KW auf der Kaltseite, so daß insgesamt 6000 Kcalorien/KW-Stunde von der Wärmepumpe erzeugt werden.The performance figures occurring here provide a useful performance of 3500 Kcalories // KW on the warm side and 2500 Kcal / KW on the cold side, so that a total of 6000 kcalories / KW-hour are generated by the heat pump.
Dieser hohe Effekt erbringt eine hohe, bisher kaum erreichte Wirtschaftlichkeit einer mit CCL3F- bzw. C2F3CL3-Flotte betriebenen Entfettungs-Reinigungsanlage.This high effect produces a high level of economic efficiency that has not been achieved so far a degreasing and cleaning system operated with a CCL3F or C2F3CL3 fleet.
Außerdem entfällt jeder Wasser- und Dampfverbrauch. Außer elektrischer Energie wird keine weitere Energie benötigt, was dem Umweltschutzwunsch entspricht.In addition, there is no need for any water or steam. Except electrical Energy no further energy is required, which corresponds to environmental protection requirements.
Beschreibunz der Erfindung Anlazenfunktion: Siehe aueh Bl. 1 und 2 Die aus dem gekühlten Tank 1 entnommene Reinigungsflotte CCL3F bzw. C2F3CL3 wird von der Pumpe 11 aus dem Dank 1 gesaugt und in den Reinigungstank 12 gedruckt, wo durch Berührung der Flotte mit dem Reinigungs-Entfettungsgut eine Reinigung bzw. Entfettung erfolgt.Description of the invention application function: See also sheets 1 and 2 The cleaning liquor CCL3F or C2F3CL3 removed from the cooled tank 1 becomes sucked by the pump 11 from the thanks 1 and printed into the cleaning tank 12, where by touching the liquor with the cleaning and degreasing material, cleaning or Degreasing takes place.
Die aus dem Tank austretende Schmutzflotte wird ganz oder teilweise dem Destillator 5 zugefiihrt, wo die Trennung der Schmutz- und Petteile aus der Flotte erfolgt. Hiernach wird das Reindestillat im Kondensator 6 verflüssigt und iiber einen Wasserscheider dem Reintank zugeführt. Aus diesem saugt eine Pumpe das Reindestillat ab, um es iiber einen Flottenstandregeler in den Reindestillatbehälter zu fördern, wo eine Verdampfung erfolgt. Der entstehende Sattdampf wird durch einen weiteren Erhitzer auf etwa + 50 Grad s erhitzt und damit zur Trocknung der entfetteten Waren benutzt.The dirty liquor emerging from the tank is wholly or partially fed to the distillator 5, where the separation of the dirt and waste parts from the Fleet takes place. The pure distillate is then liquefied in the condenser 6 and fed to the clean tank via a water separator. A pump sucks it out of this The pure distillate is transferred to the pure distillate container via a liquor level regulator promote where evaporation occurs. The resulting saturated steam is through a Another heater heated to about + 50 degrees s and thus used to dry the defatted Goods used.
