Abstract

Prevention of deposits and condensate of settled pollutants in the installation for cleaning off gas from impregnators or coaters is ensured by preheater (6). The polluted air from dryers (1, 2) is fed to heat exchanger (2) by blower (5), when warm it is transferred to burner (1) for the thermal elimination of the pollutants. The heating medium for the dryers receives its energy from heat exchanger (2) and the return circuit includes hot water exchanger (4).

Description

Thermische Abluftreinigungsanlage Thermal exhaust air purification system

Die vorliegende Erfindung bezieht sich auf eine thermische Abluftreinigungsanlage, die einen Verbrenner, Wärmeaustauscher, Erhitzer für Wärmeübertragungsmittel Heißwasserwärmeaustauscher und einen Abluftventilator enthält. Derartige Abluftreinigungsanlagen werden z.B. bei Imprägniere und Beschichtungsanlagen nachgeschaltet, um schadstoffhaltige Abluft zu reinigen. Die Abgase von Imprägnierl und Beschichtungsanlagen enthalten häufig organische Lösungsmittel und flüchtige Kunststoffanteile.The present invention relates to a thermal exhaust air purification system, which include a burner, heat exchanger, heater for heat transfer medium, hot water heat exchanger and includes an exhaust fan. Such exhaust air cleaning systems are e.g. downstream of impregnation and coating systems to remove contaminated exhaust air to clean. The exhaust gases from impregnation and coating systems often contain organic solvents and volatile plastic components.

Es hat sich gezeigt, daß im Laufe des Betriebs sich Ablagerungen und Kondensate in den Abluftleitungen bilden können, die zu einer Querschnittsverengung und damit zu einer Störung führen können, Der vorliegenden Erfindung liegt die Aufgabe zugrunde, Ablagerungen und Kondensate in den Abluftleitungen der vorgenannten Reinigung sanlagen, die sich aus den abgesetzten Schadstoffen der Abluft bilden können, zu verhindern.It has been shown that deposits and Condensates can form in the exhaust ducts, leading to a narrowing of the cross-section and thus can lead to a malfunction. The object of the present invention is based on deposits and condensates in the exhaust ducts of the aforementioned cleaning sanitary systems that can form from the pollutants deposited in the exhaust air impede.

Gelöst wird die Aufgabe dadurch, daß die Abluftleitung zum Wärmeaustauscher mindestens an ihreo Anfang mit einer Vorwärmeeinrichtung versehen wird.The object is achieved in that the exhaust air line to the heat exchanger is provided with a preheating device at least at the beginning.

In einer besonderen Ausführungsfor- ist die Vorwärmeeinrichtung an der Abluftleitung mit einer so Erhitzer für Wärmeübertragungsmi ttel führenden Leitung verbunden. Damit wird eine rationelle Ausnutzung der Abluftwärwe erreicht.In a special embodiment, the preheating device is on the exhaust air line with a line leading to a heater for heat transfer media tied together. This means that the exhaust air heat is used efficiently.

Die Erfindung wird im folgenden anhand der Zeichnung an einem Ausführungsbeispiel dargestellt.The invention is illustrated below with reference to the drawing using an exemplary embodiment shown.

Die schadstoffhaltige Abluft der Trockner 1 und 2 wird über einen Abluftventilator 5 dem Wäreeaustauscher 2 der thertischen Abluftreinigungsanlage zugeführt. Nach Erwärmung geht die Abluft in den Verbrenner 1 über und wird dort von den Schadstoffen befreit. Auf dem Wege durch den Wärmeaustauscher 2 wird in dem Erhitzer für Wärmeübertragungsoittel 3 die Energie zur Betreibung der Trockner 1 und 2 erzeugt. Iu nachgeschalteten Heißwasserwärmeaustauscher 4 erfolgt die in den Rücklauf geschaltete Nacherwärmung des betrieblichen Hochdruckheißwasser (HDHw). Anschließend verläßt die gereinigte Abluft die Reinigungsanlage über einen Schornstein.The pollutant-containing exhaust air from dryers 1 and 2 is via a Exhaust fan 5 to the heat exchanger 2 of the thermal exhaust air purification system fed. After heating, the exhaust air passes into the burner 1 and is there freed from the pollutants. On the way through the heat exchanger 2, in the heater for heat transfer means 3 the energy to operate the dryer 1 and 2 generated. Iu downstream hot water heat exchanger 4 takes place in reheating of the operational high-pressure hot water (HDHw) switched to the return. The cleaned exhaust air then leaves the cleaning system via a chimney.

Zur Verhinderung von Ablagerungen und londensaten aus der Abluft der Trockner 1 und 2 in den zur thermischen Abluftreinigungsanlage führenden Rohrleitungen, die sich aus den abgesetzten Schadstoffen der Abluft bilden können, ist am Anfang der Abluftleitung eine Vorwäreeinrichtung 6 vorgesehen.To prevent deposits and condensation from the exhaust air of the Dryer 1 and 2 in the pipes leading to the thermal exhaust air cleaning system, which can form from the pollutants deposited in the exhaust air is at the beginning A preheating device 6 is provided for the exhaust air line.

In besonderen Fällen kann diese Vorwärmeinrichtung über eine Energieleitung mit dem Erhitzer für Wär eübertragungaoittel 3 verbunden sein. Hierdurch wird eine rationelle Ausnutzung der Energie zusätzlich bewirkt.In special cases, this preheating device can be connected to a power line be connected to the heater for heat transfer agent 3. This creates a rational use of energy also causes.
