Neben einer Ausschaltung der Brandgefahr gewährleistet das erfin dungsgemäße Verfahren auch einen verbesserten Emissionsschutz.In addition to eliminating the risk of fire, the erfin guarantees Process according to the invention also improved emission protection.
Weiterbildungen und zweckmäßige Ausgestaltungen der Erfindung sind in den Unteransprüchen charakterisiert.Further developments and expedient refinements of the invention are characterized in the subclaims.
Die Erfindung wird im nachstehenden anhand der Zeichnung erläu tert, die ein Ausführungsbeispiel einer Anlage zum Absaugen von Gasen und Dämpfen sowie von Kleinpartikeln und zur Reinigung des Absaugluftstroms bei einer Spanplattenpresse schematisch veranschaulicht.The invention is explained below with reference to the drawing tert, which is an embodiment of a system for vacuuming Gases and vapors as well as small particles and for cleaning the Extraction air flow in a chipboard press schematically illustrated.
Wie aus der Zeichnung ersichtlich ist, werden die Spanplatten (10) beispielsweise mittels einer zwei umlaufende Endlos- Metallbänder (11, 12) enthaltenden Presse (13) bei entsprechender Temperatur mit dem notwendigen Druck zusammengepreßt. Über die in der Baueinheit (14) installierten Erfassungselemente (15) mit den Verbindungsleitungen (39), die diesen strömungsmäßig jeweils nachgeordneten Vordüsen (16) und die Zuleitungsabschnitte (17) gelangen die durch den als Radialventilator ausgebildeten Absaug ventilator (18) abgesaugten Gase und Dämpfe sowie die von den Rändern der Spanplatten (10) abgesaugten Kleinpartikel in die Absaugleitung (19). Die Gase und Dämpfe bestehen dabei überwie gend aus Fetten, Paraffinen, Harzen, Phenolen und Formaldehyd.As can be seen from the drawing, the particle boards ( 10 ) are pressed together, for example by means of a press ( 13 ) containing two continuous metal belts ( 11 , 12 ) at the appropriate temperature and with the necessary pressure. Via the detection elements ( 15 ) installed in the structural unit ( 14 ) with the connecting lines ( 39 ), the downstream flow nozzles ( 16 ) and the feed line sections ( 17 ) pass through the suction fan ( 18 ) designed as a radial fan and exhaust gases and Vapors and the small particles sucked from the edges of the chipboard ( 10 ) into the suction line ( 19 ). The gases and vapors mainly consist of fats, paraffins, resins, phenols and formaldehyde.
Mittels einer Pumpe (21) wird aus dem in der Anlage (28) befind lichen Wiederaufbereitungsbecken (20) über die Zuleitung (32) Waschflüssigkeit in die Verteilerleitung (23) eingespeist, die jeweils anteilig über die geöffneten Absperrschieber (22) in die Vordüsen (16) gelangt und von diesen in die Absaugleitung (19) eingedüst wird. Dadurch wird die Absaugluft unter ihre Taupunkts temperatur abgekühlt (Sättigungskühlung), so daß ein Großteil der gas- und dampfförmigen Verunreinigungen auskondensiert und Aero sole bildet. Zugleich wird die Absaugleitung (19) gespült und von Ablagerungen freigehalten. Die Vordüsen bilden außerdem eine wirksame Flammensperre bei etwaigen Rohrleitungsbränden.By means of a pump ( 21 ), washing liquid is fed into the distribution line ( 23 ) from the reprocessing basin ( 20 ) in the system ( 28 ) via the feed line ( 32 ), each of which is partly fed into the pre-nozzles ( 22 ) via the open gate valve ( 22 ). 16 ) arrives and is injected into the suction line ( 19 ). As a result, the suction air is cooled below its dew point temperature (saturation cooling), so that a large part of the gaseous and vaporous contaminants condense out and form aerosol. At the same time, the suction line ( 19 ) is rinsed and kept free of deposits. The pre-nozzles also form an effective flame arrester in the event of pipe fires.
Die sich an die Baueinheit (14) anschließende Abscheidezone (24) enthält einen Tropfenabscheider (25), dem strömungsmäßig eine Hauptdüse (26) vorgeordnet ist, in die einerseits die Absauglei tung (19) und andererseits die Waschflüssigkeitsverteilerleitung (23) einmündet, wobei der Zulauf von Waschflüssigkeit durch einen Absperrschieber (33) im Bedarfsfall einstellbar bzw. unterbindbar ist.The separating zone ( 24 ) adjoining the structural unit ( 14 ) contains a droplet separator ( 25 ), upstream of which a main nozzle ( 26 ) is arranged upstream, into which the suction line ( 19 ) on the one hand and the washing liquid distributor line ( 23 ) on the other hand, the The supply of washing liquid can be adjusted or prevented by a gate valve ( 33 ) if necessary.
In der Hauptdüse (26) werden die im Absaugluftstrom befindlichen Verunreinigungen (luftfremde Stoffe) intensiv mit Waschflüssig keit benetzt und an diese gebunden. Die mit den Verunreinigungen durchsetzte Waschflüssigkeit wird im Tropfenabscheider (25) wie der vom Absaugluftstrom getrennt, und die Verunreinigungen (Trü be) gelangen über eine Rücklaufleitung (27) zurück in das Wiederaufbereitungsbecken (20) der Anlage (28), in dem die Verun reinigungen wieder von der Waschflüssigkeit separiert werden. Die schweren Stoffe setzen sich ab und werden mit einem Sedimenträu mer (34) ausgetragen. Die leichteren Stoffe bilden eine Schwimm schlammschicht, die fit einem Schlammschieber (29) zu einer Räu merkette (38) transportiert und durch diese ebenfalls ausgetragen wird. Der Flüssigkeitsstand im Wiederaufbereitungsbecken (20) wird durch eine Niveauüberwachung (30) in Verbindung mit einer Zulaufarmatur (31) und für Störfälle mit Hilfe eines Überlaufs konstant gehalten.In the main nozzle ( 26 ), the impurities in the exhaust air flow (non-air substances) are wetted intensively with washing liquid and bound to them. The washing liquid interspersed with the impurities is separated in the droplet separator ( 25 ) like that from the suction air flow, and the impurities (cloudy) are returned via a return line ( 27 ) to the reprocessing basin ( 20 ) of the system ( 28 ), in which the impurities are cleaned be separated from the washing liquid again. The heavy substances settle and are discharged with a sediment debris ( 34 ). The lighter substances form a floating sludge layer, which is transported by a sludge pusher ( 29 ) to a broach chain ( 38 ) and is also discharged through it. The liquid level in the reprocessing basin ( 20 ) is kept constant by level monitoring ( 30 ) in connection with an inlet fitting ( 31 ) and in the event of malfunctions using an overflow.
Die von der Waschflüssigkeitspumpe (21) über die Speiseleitung (32) in die Verteilerleitung (23) geförderte Waschflüssigkeit teilt sich bei geöffneten Absperrschiebern (22) und (33) in zwei Teilströme auf, von denen der eine die Hauptdüse (26) beauf schlagt und der andere die Vordüsen (16) speist.The washer fluid pumped by the washer fluid pump ( 21 ) via the feed line ( 32 ) into the distributor line ( 23 ) is divided into two partial flows when the gate valves ( 22 ) and ( 33 ) are open, one of which strikes the main nozzle ( 26 ) and the other feeds the pre-nozzles ( 16 ).
Nach einem weiteren Gedanken der Erfindung wird das Laufrad des Absaugventilators (18) ebenfalls mit Waschflüssigkeit bedüst, die entweder aus dem Wiederaufbereitungsbecken (20) im Kreislaufver fahren oder separat als frische Flüssigkeit zugeführt wird. Da durch werden Anbackungen am Ventilatorlaufrad durch im Absaugluftstrom etwa noch enthaltene Restverunreinigungen vermie den. Ferner werden restliche Verunreinigungen nun im Absaugventi lator (18) mit Waschflüssigkeit benetzt und an diese gebunden. Im dem Absaugventilator (18) nachgeordneten Tropfenabscheider (35) wird die Waschflüssigkeit mit den Verunreinigungen wieder vom Luftstrom getrennt und läuft durch die Leitung 27′ ab ins Wiederaufbereitungsbecken (20).According to a further idea of the invention, the impeller of the suction fan ( 18 ) is also sprayed with washing liquid which either runs from the reprocessing basin ( 20 ) in the Kreislaufver or is supplied separately as fresh liquid. Since caking on the fan impeller is avoided by any residual impurities still contained in the exhaust air flow. Furthermore, residual impurities are now wetted in the suction fan ( 18 ) with washing liquid and bound to it. In the suction fan ( 18 ) downstream droplet separator ( 35 ), the washing liquid with the contaminants is separated from the air flow again and runs through line 27 'into the reprocessing basin ( 20 ).
Die gereinigte Abluft strömt über einen Abluftkamin (36) mit vor geschaltetem Schalldämpfer (37) in die Atmosphäre.The cleaned exhaust air flows into the atmosphere via an exhaust air chimney ( 36 ) with an upstream silencer ( 37 ).
Durch flexible Ausbildung der Zuleitungen (17) und (17′) zur Ab saugleitung (19) und zur Verteilerleitung (23) für die Waschflüs sigkeitszufuhr können die Absaughauben (15) mit der jeweils zuge ordneten Vordüse (16) und dem zugehörigen Absperrschieber (22) im Bedarfsfall relativ zueinander verschoben werden.Due to the flexible design of the supply lines ( 17 ) and ( 17 ') to the suction line ( 19 ) and to the distributor line ( 23 ) for the liquid supply of the washing liquid, the suction hoods ( 15 ) with the respectively assigned pre-nozzle ( 16 ) and the associated gate valve ( 22 ) can be moved relative to each other if necessary.
Durch eine leicht demontierbare, eventuell flexible, Ausbildung der Rohrleitungen zwischen den Erfassungselementen (15) und den Vordüsen (16) wird ein schnelles Beseitigen von eventuell auftre tenden Ablagerungen in diesem Bereich ermöglicht. An easily removable, possibly flexible, design of the pipelines between the detection elements ( 15 ) and the pre-nozzles ( 16 ) enables rapid removal of any deposits that may occur in this area.
Zur Unterstützung der Abscheidung der Luftverunreinigungen kön nen in die Absaugleitung 19 aus einem Vorratsbehälter mittels einer Pumpe 40 über eine Zuleitung 41 Zusätze wie Koagulierungs mittel oder Emulgatoren eingespeist werden. Dies geschieht zweckmäßigerweise im Verwirbelungsbereich vor der Hauptdüse 26. Des weiteren können der im Wiederaufbereitungsbecken 20 befind lichen Waschflüssigkeit Oxidationsmittel zugeführt werden, um eventuelle Giftstoffe zu binden bzw. chemisch zu neutralisieren.To support the separation of air pollutants NEN in the suction line 19 from a reservoir by means of a pump 40 via a feed line 41 additives such as coagulants or emulsifiers can be fed. This expediently takes place in the swirling area in front of the main nozzle 26 . Furthermore, the washing liquid located in the reprocessing basin 20 can be supplied with oxidizing agents in order to bind any toxins or to neutralize them chemically.
Die Waschflüssigkeit kann im Bedarfsfall abhängig vom Verunrei nigungsgrad und der Temperatur der Absaugluft mengenmäßig und hinsichtlich ihrer Temperatur geregelt in die Absaugleitung 19 eingespeist werden.If necessary, the washing liquid can be fed into the suction line 19 in a quantity-dependent manner and in terms of its temperature, depending on the degree of contamination and the temperature of the suction air.
