Description

Dephlegmator und Vorwärmer für Ammoniak-Abtreibeapparate. Beire Verarbeiten von Ammoniakwasser tritt mit dem abgetriebenen Ammoniak eine große Menge Dampf aus dem Abtreibapparat. Dieser Begleitdampf spielt eine große Rolle beim Dampfverbrauch des Abtreibapparates. Er beträgt bei gut geleiteten Betrieben (las i- bis 8fache des Ammoniaks, meistens ist er aber bedeutend höher, so daß er über 50 Prozent der ganzen zur Abtreibung benötigten Dampfmenge betragen kann. Außer den großen direkten Kosten für diesen Dampf verursacht derselbe je- nach der Verwendung des Ammoniaks auch noch Betriebsschwierigkeiten und indirekte Kosten.Dephlegmator and preheater for ammonia abortion machines. When ammonia water is processed, a large amount of steam escapes from the stripping apparatus with the ammonia that is driven off. This accompanying steam plays a major role in the steam consumption of the stripping apparatus. In well-managed establishments it is (1 to 8 times as much as ammonia, but it is usually much higher, so that it can amount to over 50 percent of the total amount of steam required for abortion. In addition to the large direct costs for this steam, it causes the same, depending on the situation) the use of ammonia also adds operational difficulties and indirect costs.

Mit Hilfe der vorliegenden Erfindung ist es nun möglich, ohne jede Wartung den Dampf von dem Ammoniak bis auf die der Tension des Wasserdampfes bei der Temperatur des Ammoniaks entsprechende Menge zu trennen und die Verdampfungswärme des niedergeschlagenen Dampfes voll auszunutzen, wobei man es ganz genau in der Hand hat, die Temperatur des Ammoniaks beliebig einzustellen.With the help of the present invention it is now possible without any Maintain the vapor from the ammonia except for the tension of the water vapor to separate the amount corresponding to the temperature of the ammonia and the heat of vaporization to take full advantage of the precipitated steam, being very precise in the Hand has to adjust the temperature of the ammonia as desired.

Eine zweckmäßige Ausführungsform der vorliegenden Erfindung ist auf der Zeichnung dargestellt. 21 ist ein allseitig geschlossener Behälter, welcher durch Platte B in zwei Teile getrennt ist. D ist ein Rohrsystem, oben (bei B) offen, unten (bei C) geschlossen. E ist eine im oberen Teil (Dampfraum) des Behälters befindliche Rohrschlange. In den Rohren D befindet sich eine Flüssigkeit, deren Siedepunkt den Arbeitsbedingungen angepaßt zweckmäßig zwischen 70 und 95° liegt.An expedient embodiment of the present invention is shown in the drawing. 21 is a container which is closed on all sides and which is separated into two parts by plate B. D is a pipe system, open at the top (at B), closed at the bottom (at C). E is a coil located in the upper part (vapor space) of the container. In the pipes D there is a liquid, the boiling point of which, adapted to the working conditions, is expediently between 70 and 95 °.

Beirr Betrieb des Apparates leitet man durch F die aus denn Abtreibapparat kommenden Dämpfe ein. Diese treten durch Öffnungen L zwischen die Rohre D und erhitzen die Flüssigkeit in denselben zum Sieden. Es wird nun alles Ammoniak auf den Siedepunkt dieser Flüssigkeit äbgekühlt, und es verläßt den Apparat bei G mit nur' so viel Wasser, als der Tension desselben bei der betreffenden Temperatur entspricht, während durch k das niedergeschlagene Wasser abläuft. Bei H wird das zum Abtreibapparat laufende Rohwasser in die Schlange E ein- und bei I zum Abtreibappar at weitergeführt. An der Schlange E werden die aus der in den Rohren befindlichen Flüssigkeit entweichenden -Dämpfe niedergeschlagen und. die Wärme an das Rohti#asser abgegeben, so daß die gesamte Wärme zur Vorwärmung des Rohwassers ausgenutzt wird.When the apparatus is in operation, F is used to introduce the vapors coming from the abortion apparatus. These pass through openings L between the tubes D and heat the liquid in them to boiling. All the ammonia is then cooled down to the boiling point of this liquid, and it leaves the apparatus at G with only as much water as corresponds to its tension at the temperature in question, while the precipitated water runs off through k. At H the raw water running to the abortion apparatus is fed into the queue E and at I to the abortion apparatus at. The vapors escaping from the liquid in the pipes are precipitated at the snake E and. the heat is transferred to the raw water, so that the entire heat is used to preheat the raw water.
