Abstract

Röhrenkreuzkühler werden im Gegenstromverfahren zum Abkühlen von gasförmigen Alkoholdämpfen in den flüssigen Zustand verwendet. Das ist Kühlkreislauf Nr. 1 mit Frischwasser.Im oberen Teil des Röhrenkühlers befindet sich ein zweiter Röhrenkühler, der die Rohre durchkreuzt und ein getrennter Kreislauf ist.Die Wärme vom Alkoholdampf wird auf das Wasser vom Kühlkreislauf Nr. 1 übertragen und zugleich auch auf den Kühlkreislauf Nr. 2.Somit können diese Wärmeeinheiten mit dem Kühlkreislauf Nr. 2 für den Pufferspeicher in die Heizung abgegeben werden.Die Wärmeeinheiten, die im Kühlkreislauf Nr. 2 abgegeben werden, entlasten den Kühlkreislauf Nr. 1.Somit wird im Kühlkreislauf Nr. 1 auch Frischwasser gespart.Mit dem Kühlkreislauf Nr. 3, der den Röhrenkühler unten durchkreuzt, kann man mit einer Kältemaschine das Destillat abkühlen, dann ist der Wasserverbrauch gleich Null.Der Röhrenkreuzkühler kann mit zwei und mehreren Kühlkreisläufen gebaut werden.Tube coolers are used in the countercurrent process to cool down gaseous alcohol vapors to the liquid state. This is cooling circuit No. 1 with fresh water. In the upper part of the tube cooler there is a second tube cooler, which crosses the tubes and is a separate circuit. The heat from the alcohol vapor is transferred to the water of cooling circuit No. 1 and at the same time to the cooling circuit No. 2. Thus, these heat units can be released into the heating system with cooling circuit no. 2 for the buffer tank. The heat units that are released in cooling circuit no. 2 relieve cooling circuit no Fresh water saved. With the cooling circuit No. 3, which crosses the tube cooler below, you can cool the distillate with a chiller, then the water consumption is zero. The tube cross cooler can be built with two or more cooling circuits.

Description

Röhrenkreuzkühler für Brennerei- und Kälteanlagen. Bei der Alkohol- oder Destillatherstellung werden Dämpfe vom gasförmigen Zustand wieder in den flüssigen Aggregatzustand abgekühlt.Tube cross cooler for distillery and refrigeration systems. During the production of alcohol or distillates, vapors are cooled down from the gaseous state back to the liquid state.

Am besten haben sich Röhrenkühler im Gegenstromverfahren bewährt. Das verwendete Kühlwasser (kaltes Frischwasser im Kühlkreislauf Nr. 1) wird in den meisten Fällen in den Abfluss geleitet.Tube coolers in the counterflow process have proven to be best. In most cases, the cooling water used (cold fresh water in cooling circuit no. 1) is discharged into the drain.

Mit einem Röhrenkreuzkühler kann die Wärme über einen zweiten Kühlkreislauf Nr. 2 in die Heizung gespeist werden.With a tube cross cooler, the heat can be fed into the heating system via a second cooling circuit No. 2.

Wichtig ist, dass die Röhrenoberfläche groß genug ausgelegt ist.It is important that the tube surface is large enough.

Der Röhrenkreuzkühler (Kühlkreislauf Nr. 2) befindet sich im oberen Teil des Röhrenkühlers und ist mit dem Heizungskreislauf verbunden, Zeichnung 1.The tube cross cooler (cooling circuit no. 2) is located in the upper part of the tube cooler and is connected to the heating circuit, drawing 1 .

Somit können die höheren Temperaturbereiche in die Heizung gespeist werden. Der Alkoholdampf hat zu Beginn des Brennvorgangs eine Temperatur von ca. 85° Celsius und steigert sich dann bis über 95° Celsius.Thus, the higher temperature ranges can be fed into the heater. At the beginning of the burning process, the alcohol vapor has a temperature of approx. 85° Celsius and then increases to over 95° Celsius.

Der Kreuzkühler (Kühlkreislauf Nr. 2) wird mit einer Zirkulationspumpe und mit einer Differenzsteuerung versehen, oder könnte auch mit Schwerkraft je nach Gebäudeumständen betrieben werden.The cross cooler (cooling circuit #2) will be provided with a circulation pump and differential control, or could also be gravity driven depending on the building circumstances.

Ist der Heizungspufferspeicher schon mit 70° Celsius geladen, dann ist es immer noch möglich, die darüberliegende Temperatur von 70° Celsius bis 95° Celsius abzunehmen.If the heating buffer storage is already loaded with 70° Celsius, then it is still possible to take the temperature from 70° Celsius to 95° Celsius.

Der Kühlkreislauf Nr. 1 kühlt dann nur noch die verbleibende Restwärme ab, der vom Kühlkreislauf Nr. 2 nicht abgenommen wurde.Cooling circuit no. 1 then only cools down the remaining residual heat that was not removed by cooling circuit no. 2.

Je mehr Wärmeeinheiten in die Heizung geladen werden, desto mehr Frischwasser wird eingespart. Mit dem Kühlkreislauf Nr. 3, der den Röhrenkühler unten durchkreuzt, kann man mit einer Kältemaschine das Destillat abkühlen, Zeichnung 1. Somit ist der Frischwasserverbrauch gleich Null. Nur eine Kühlerfüllung in Kühlkreislauf Nr. 1 ist notwendig, um die Anlage zu betreiben.The more heat units loaded into the heater, the more fresh water is saved. With cooling circuit no. 3, which crosses the tube cooler below, you can cool down the distillate with a refrigeration machine, drawing 1 . Thus, the fresh water consumption is zero. Only one cooler filling in cooling circuit no. 1 is necessary to operate the system.

Zeichnung 2 ist die Draufsicht im Schnitt vom Kühlkreislauf Nr. 2.drawing 2 is the sectional plan view of the No. 2 cooling circuit.
