Abstract

The subject of the invention is a disposal station for refrigerant and compressor oil. This disposal station has the function of removing refrigerant and oil from the devices which are to be disposed of, of collecting (temporarily storing) the refrigerant and oil and of separating the oil and refrigerant accumulated in this manner to as large an extent as possible and of making them available for further usage. The disposal station is based on the process of separating the accumulated materials by means of phase change of the refrigerant, brought about by pressure reduction in the collecting container. The disposal station is to be operated decentrally (for example in communal recycling centres, at landfill sites, on refuse collection vehicles) in order to supply the materials accumulated there for further usage in large quantities.

Description

Ausgehend von der derzeitigen SituationBased on the current situation

  • - Umweltbelastung durch Kältemittel (R 11, R 12, . . .)- Environmental pollution caused by refrigerants (R 11 , R 12 ,...)
  • - Umweltbelastung durch Öl (Kompressorenöl)- Environmental pollution caused by oil (compressor oil)
  • - allein in der BRD fallen im Jahr 3,5 Mio. Kühl- und Gefrier­ geräte (ohne Klimaanlagen) als Abfall an, d. h. ca. 500 t Kältemittel und 1 Mio. l Kompressorenöl gelangen in die Umwelt- In the FRG alone 3.5 million refrigerators and freezers fall each year appliances (without air conditioning) as waste, d. H. approx. 500 t Refrigerant and 1 million l of compressor oil are released into the environment
  • - es existieren Recycling-Verfahren für Kältemittel (Fa. Gramkow in Sonderborg, Fa. Hoechst)- There are recycling processes for refrigerants (Gramkow in Sonderborg, Hoechst)
  • - es existieren Recycling- bzw. Beseitigungs-Verfahren für Öle- There are recycling and disposal processes for oils

stellt sich das Problem, die Verbindung zwischen dem Ort der Abfall- Entstehung und dem des Abfall-Recycling, der Abfall-Weiterverwertung bzw. -Beseitigung herzustellen.the problem arises, the connection between the location of the waste Origin and that of waste recycling, waste recycling manufacture or elimination.

Diese Verbindung zwischen "Abfall-"Quelle" und "Abfall-Senke" beinhaltet Kältemittel und ÖlThis connection between "waste" source "and" waste sink "implies Refrigerant and oil

  • - aus dem zu entsorgenden Gerät zu entnehmen- to be removed from the device to be disposed of
  • - zwischenzulagern (sammeln)- intermediate storage (collecting)
  • - weitestgehend voneinander zu trennen, zu reinigen und sortenrein einer Weiterverwendung bereitzustellen.- to be separated as far as possible from each other, cleaned and sorted to provide for further use.

Kältemittel und Öl zu trennen ist auch Gegenstand des US-Patents 43 64 236 (Lower et al; "Kältemittel-Rückgewinnung und Wieder- Abfüll-System"); das dort beschriebene Verfahren entspricht dem eines normalen Ölabscheiders (wie aus der Druckluft-Technik bekannt) und hat den Nachteil, daß das so rückgewonnene Öl unter Normal-Druck (1 bar) durch das im Öl gelöste Kältemittel aufschäumt, und das Kältemittel wiederum nur unvollständig vom Öl "gereinigt" ist.Separating refrigerant and oil is also the subject of the US patent 43 64 236 (Lower et al; "Refrigerant Recovery and Recovery Filling system "); the procedure described there corresponds to that of one normal oil separator (as known from compressed air technology) and has the disadvantage that the oil thus recovered under normal pressure (1 bar) due to the refrigerant dissolved in the oil, and the refrigerant is incompletely "cleaned" of the oil.

Das der Erfindung zugrunde liegende Verfahren wird an Hand der Bilder 1 und 2 erläutert. The method on which the invention is based is explained with reference to Figures 1 and 2.

Der Aufbau der Entsorgungs-Station (EST) ist in Bild 1 dar­ gestellt.The structure of the disposal station (EST) is shown in Figure 1.

Die EST wird dezentral betrieben, z. B. in kommunalen Recycling-Zentren, bei Mülldeponien oder auf Müllfahrzeugen. Dabei werden Kältemittel und Öl im Sammelbehälter (1) der EST gesammelt und zwischengespeichert. Um die Stoffe einer Weiter­ verarbeitung zuzuführen, wird der Sammelbehälter periodisch oder nach Bedarf in die Behälter (2) und (3) entleert.The EST is operated decentrally, e.g. B. in municipal recycling centers, at landfills or on garbage trucks. Refrigerant and oil are collected and temporarily stored in the EST storage tank ( 1 ). In order to feed the substances for further processing, the collection container is emptied periodically or as required into containers ( 2 ) and ( 3 ).

In der Praxis kann dies bedeuten, daß ein Tankfahrzeug die dezentralen EST's anfährt, um Öl und Kältemittel aufzunehmen. Durch die Größe des Sammelbehälters (1) kann so eine optimale Sammelfrequenz vorbestimmt werden.In practice, this can mean that a tanker drives to the decentralized ESTs to take up oil and refrigerant. The size of the collecting container ( 1 ) allows an optimal collecting frequency to be predetermined.

Die Arbeitsweise der EST soll im folgenden an Hand von Bild 2 dargelegt werden. Die EST arbeitet in 3 Phasen:The mode of operation of the EST will be explained in the following with the help of Figure 2. The EST works in 3 phases:

  • I. Kältemittel und Öl aus den zu entsorgenden Geräten aufnehmen,I. Refrigerant and oil from the devices to be disposed of record, tape,
  • II. Kältemittel an Behälter (2) abgeben,II. Deliver refrigerant to tank ( 2 ),
  • III. Öl an Behälter (3) abgeben.III. Dispense oil to container ( 3 ).

Diesen Phasen entsprechen die Ventil-Stellungen I, II, III der Mehrweg-Ventile (6).The valve positions I, II, III of the reusable valves ( 6 ) correspond to these phases.

Phase IPhase I

  • Kältemittel und Öl der zu entsorgenden Geräte werden mittels Kompressor (4) in den Sammelbehälter (5) ge­ pumpt.Refrigerant and oil of the devices to be disposed of are pumped into the collection container ( 5 ) by means of a compressor ( 4 ).

Die EST verbleibt so lange in Phase I, bis der Sammelbehälter (5) ge­ leert wird; der Sammelbehälter (5) befindet sich dann in dem Zustand, daß Kältemittel und Öl, wie in Bild 2 dargestellt, geschichtet sind.The EST remains in phase I until the collection container ( 5 ) is emptied; The collecting container ( 5 ) is then in the state that the refrigerant and oil are layered as shown in Figure 2.

Phase IIPhase II

  • Das Kältemittel des Sammelbehälters (5) wird in den Behälter (2) übernommen. Dabei wird das Kältemittel durch Unterdruck gasförmig aus Sammelbehälter (5) mittels Kompressor (4) entnommen, der es dann in den Behälter (2) pumpt. Durch den dabei im Sammelbehälter (5) entstehenden Unterdruck wird die darin enthaltene Feuchtigkeit (aus Öl und Kältemittel) gemeinsam mit dem Kältemittel ent­ nommen und an einen Trockner abgegeben.The refrigerant in the collection container ( 5 ) is transferred to the container ( 2 ). The refrigerant is removed in gaseous form from the collecting container ( 5 ) by means of a compressor ( 4 ), which then pumps it into the container ( 2 ). Due to the resulting negative pressure in the collecting container ( 5 ), the moisture contained therein (from oil and refrigerant) is removed together with the refrigerant and released to a dryer.

Die EST verbleibt solange in Phase II, bis ein vorgegebener Unter­ druck im Sammelbehälter (5) erreicht ist. The EST remains in phase II until a predetermined vacuum in the collection container ( 5 ) is reached.

Phase IIIPhase III

  • Das Öl des Sammelbehälters (5) wird in den Be­ hälter (3) übernommen.The oil in the reservoir ( 5 ) is transferred to the reservoir ( 3 ).

Am Ende der Phase III herrscht im Sammelbehälter (5) Unterdruck; der Sammelbehälter ist leer.At the end of phase III, there is negative pressure in the collecting container ( 5 ); the collection container is empty.
