Abstract
Description
Die Erfindung betrifft das "TRINAT" Behandlungs- und Trocknungsverfahren zur Aufbereitung von Klär-und/oder Industrieschlämmen mit organischen oder anorganischen Anteilen mittels Mischung mit faserhaltigen Zuschlagstoffen und Trocknung in einem geschlossenen Luftkreislauf, sowie Vorrichtungen zur Durchführung des Verfahrens.The invention relates to the "TRINAT" treatment and Drying process for the treatment of clarification and / or Industrial sludges with organic or inorganic components by mixing with fiber-containing additives and Drying in a closed air circuit, as well Devices for performing the method.
Bei dem "Trinat" Verfahren werden Schlämme zur Verbesserung ihrer Entwässerbarkeit und späteren Verwertung mit faserhaltigen Stoffen gemischt und in einem Nieder temperaturtrocknungsverfahren mit geschlossenem Luftkreislauf nachbehandelt. Die schonende Trocknung liefert werthaltige Produkte während die Brüden übers Kondensat abgeben.The "Trinat" process uses sludges for improvement their drainability and later recovery with fibrous fabrics mixed and in a low closed temperature drying process Air circuit aftertreated. Gentle drying delivers valuable products while the brothers dispense over the condensate.
Der Feststoffrückstand findet Verwendung als Kompost zuschlagstoff, als Filtermaterial oder als Brennstoff zur Wärme und Stromerzeugung.The solid residue is used as compost aggregate, as filter material or as fuel for heat and power generation.
Zur Entwässerung von Schlämmen werden heute Systeme eingesetzt, deren Trocknungsgrad nicht über 50% kommt. Die anschließende thermische Trocknung ist energie aufwendig.Systems are now used to dewater sludge used, the degree of dryness does not exceed 50%. The subsequent thermal drying is energy complex.
Der Erfindung liegt die Aufgabe zugrunde, die bisherigen Verfahrensschritte zu verbessern, den Verfahrens ablauf zu modifizieren mit dem Ziel, den gesamten Schlammbehandlungsprozeß in einen Kreislaufprozeß zu überführen, und ein Minimum an Fremdenergie aufzuwenden. Schlämme, die nicht recyelbar sind, könnten immerhin noch als Energielieferant in Frage kommen und damit zur Schonung nicht regenerierbarer Energieträger beitragen.The invention is based, so far the task Process steps to improve the process to modify the process with the aim of Sludge treatment process in a cycle process to convince, and to use a minimum of external energy. Sludges that are not recyclable could still come into question as an energy supplier and thus for protection non-renewable energy sources.
In dem Fließschema gemäß Fig 1 ist mit (1) die Zuführung Der Schlamm wir in einem Eindicker (2) vorentwässert und mittels eines Förderorgans (3) in den Mischer (6) geführt. Der Behälter (4) nimmt die faserhaltigen Trockenstoffe auf, die mittels Dosieranlage (5) in den Mischer (6) gefördert werden.In the flow diagram according to FIG. 1 , the feed The sludge is pre-dewatered in a thickener ( 2 ) and fed into the mixer ( 6 ) by means of a conveyor element ( 3 ). The container ( 4 ) receives the fibrous dry substances, which are conveyed into the mixer ( 6 ) by means of a metering system ( 5 ).
Über ein Förderorgan (7) wird das Mischgut direkt einer mechanischen Entwässerung (8) oder über (8.1) dem Trockner zugeführt.The material to be mixed is fed directly to mechanical dewatering ( 8 ) or to the dryer via ( 8.1 ) via a conveyor element ( 7 ).
Mit (9) wird ein Förderorgan bezeichnet, das den entwässerten Schlamm dem Trockner (10) zuführt.With ( 9 ) a conveying device is designated, which feeds the dewatered sludge to the dryer ( 10 ).
Der dem Trockner zugeordnete Doppelmantel (11) ist als Latentwärmespeicher ausgebildet und mit einer Wärmeaustausch einrichtung versehen.The assigned double jacket ( 11 ) is designed as a latent heat storage and provided with a heat exchange device.
Im Trockner wird das Mischgut von warmer Luft umspült, die über das Gebläse (17) zugeführt wird.In the dryer, warm air flows around the mix, which is fed in via the fan ( 17 ).
Die mit Brüden und Staub beladene Luft wird im Filter (12) gereinigt und dann dem Aktivkohlefilter (13) zugeleitet. Die danach austretende Luft wird durch einen Luftwäscher (14) geleitet, von wo aus sie der Entfeuchtungsanlage (15) zu geführt wird.The air laden with vapors and dust is cleaned in the filter ( 12 ) and then fed to the activated carbon filter ( 13 ). The air subsequently escaping is passed through an air washer ( 14 ), from where it is led to the dehumidification system ( 15 ).
Mit (16) ist der Kondensatablauf bezeichnet.With ( 16 ) the condensate drain is designated.
Das getrocknete Material wird über die Zellenradschleuse (18) der Brikettieranlage (19) zugeführt und dann in den Behälter (20) ausgetragen.The dried material is fed to the briquetting system ( 19 ) via the cellular wheel sluice ( 18 ) and then discharged into the container ( 20 ).
Für mit Schwermetallen belastete Schlämme wird zwischen (2) und (6) eine Entgiftungsanlage (I) geschaltet.For sludges contaminated with heavy metals, a detoxification system (I) is switched between ( 2 ) and ( 6 ).
Claims (18)
- a. durch Schwerkraft oder technische Einrichtungen eingedickt werden
- b. dem Innenraum eines Mischers zugeführt werden
- c. über eine Dosiereinrichtung dem Mischer faserhaltige, organische Trockenstoffe in bestimmten Mischungs verhältnissen zugeführt werden.
- a. be thickened by gravity or technical equipment
- b. be fed to the interior of a mixer
- c. Via a metering device, the mixer fiber-containing, organic dry substances are fed in certain mixing ratios.
