Description
Die Neuerung bezieht sich auf eine Abluft-Zuluft-Wärmetauscheranlage, insbesondere für einen Tierstall, mit einem Wärmetauscherelement, das mit Wärmeübergangskontakt einen Abluftkanal und einen Zuluftkanal enthält, und einem offenen oder geschlossenen Waschwasser-Kreislauf, in dessen Verlauf eine Pumpe, ein Filter und wenigstens einer der Luftkanäle des Wärmetauscherelements zu dessen Durchspülung enthalten sind.The innovation relates to an exhaust air supply air heat exchanger system, in particular for an animal house, with a heat exchanger element containing a heat transfer contact an exhaust duct and a supply air duct, and an open or closed wash water circuit, in the course of a pump, a filter and at least one of the air channels of the heat exchanger element are included for the flushing.
Es ist bekannt, Stallabluft über einen Wärmetauscher abzuleiten, in dem die gleichzeitig zugeleitete Zuluft durch die in der Abluft enthaltene Wärme erwärmt wird. Die Stallabluft enthält eine gewisse Menge Schmutzpartikel, von denen ein Teil im Abluftkanal des Wärmetauschers hängen bleibt. Dies gilt allgemein, wenn die Abluft stark staubbelastet ist. Der Abluftkanal muss also von Zeit zu Zeit oder auch stetig gereinigt werden. Sollte auch die Zuluft staubbeladen sein, so kann auch der Zuluftkanal einer gelegentlichen Reinigung bedürfen. Die Reinigung erfolgt generell manuell, es kann aber auch eine Sprühanlage eingesetzt werden. Bei regelmäßigem Einsatz fallen dann große Mengen an verschmutztem Wasser an, das zwischengelagert und entsorgt werden muss. Zur Reinigung kann auch Waschwasser verwendet werden, das in einem geschlossenen Kreislauf umgewälzt wird. Für den geschlossenen Waschwasser-Kreislauf ist es nötig, für den offenen Kreislauf ist es bei starker Verschmutzung angezeigt, das Schmutzwasser durch einen Filter zu leiten und dadurch von den mitgeschwemmten Partikeln zu reinigen. Der häufige Austausch des Filters ist jedoch aufwendig und somit nachteilig.It is known to divert stable exhaust air via a heat exchanger, in which the simultaneously supplied supply air is heated by the heat contained in the exhaust air. The stable exhaust air contains a certain amount of dirt particles, a part of which gets caught in the exhaust duct of the heat exchanger. This is generally true if the exhaust air is heavily polluted. The exhaust duct must therefore be cleaned from time to time or even continuously. If the supply air is also dust-laden, the supply air duct may require occasional cleaning. The cleaning is generally manual, but it can also be used a spray system. With regular use, large amounts of contaminated water are generated, which must be stored and disposed of. For cleaning washing water can be used, which is circulated in a closed circuit. For the closed wash water circuit it is necessary, for the open circuit it is indicated in case of heavy soiling, to pass the dirty water through a filter and thereby to clean it of the entrained particles. However, the frequent replacement of the filter is complicated and thus disadvantageous.
Durch die Neuerung soll der Austausch des Filters vermieden werden oder zumindest seltener notwendig werden. Dies wird gemäß der Neuerung dadurch erreicht, dass der Filter ein Trommelfilter ist, mit einer trommelmantelförmigen Filterschicht, die eine Zulaufschichtfläche und eine Ablaufschichtfläche aufweist. Die Trommelfilter müssen nicht laufend ausgetauscht werden und können, je nach Bauart, ohne Austausch gesteuert gereinigt werden oder durch Transport einer filternden Vliesbahn ohne manuellen Eingriff erneuert werden. Solche Trommelfilter sind insbesondere für Fischzuchtanlagen bekannt.Due to the innovation, the replacement of the filter should be avoided or at least become less necessary. This is achieved according to the invention in that the filter is a drum filter with a drum-shell-shaped filter layer having a feed layer surface and a drainage layer surface. The drum filters do not need to be continuously replaced and, depending on the design, can be cleaned without replacement, or replaced by transporting a filtering nonwoven web without manual intervention. Such drum filters are known in particular for fish farms.
Bei einer ersten Ausführungsform enthält der Trommelfilter einen Waschwasserzulauf und einen Waschwasserablauf, über die der Waschwasser-Kreislauf verläuft, und einen nicht in den Kreislauf einbezogenen Schmutzwasserablauf. Vorzugsweise ist dann der Trommelfilter ein im Waschwasser-Kreislauf vom Trommelinneren zur Trommelumgebung, also von innen nach außen durchflossener Trommelfilter, was eine einfache automatische Reinigungsspülung ermöglicht. Zur automatischen Reinigungsspülung umfasst nach einer zweckmäßigen Ausführung die Anlage eine Steuereinheit, die zur Filterreinigung ein den Waschwasser-Kreislauf am Trommelfilter umkehrendes Ventil und ein die Zulaufschichtfläche des Filters mit dem Schmutzwasserablauf verbindendes Ventil steuert, wobei dann die Spülung durch zuvor gereinigtes Waschwasser erfolgt; oder umfasst eine Steuereinheit, die zur Filterreinigung ein den Waschwasser-Kreislauf am Trommelfilter unterbrechendes Ventil, ein einen Frischwasserzulauf zur Zulaufschichtfläche des Filters öffnendes Ventil und ein die Zulaufschichtfläche des Filters mit dem Schmutzwasserablauf verbindendes Ventil steuert. Mit Hilfe der Steuereinheit wird die Filterausspülung automatisch durchgeführt, und zwar entweder durch eine Zeitsteuerung der Ventilbetätigungen zur Filterreinigung, also in vorgegebenen Intervallen, oder durch eine Messeinrichtung zum Messen der Filterverschmutzung, deren Messsignal der Steuereinheit zur Regelung der Filterreinigung zugeleitet ist. Die Messeinrichtung kann beispielsweise den Staudruck des Filters, die Rückstauhöhe des Waschwassers vor dem Filter oder den Wasserpegel in einer Sammelkammer hinter dem Filter erfassen und dadurch das Signal für die Fälligkeit einer Filterrückspülung erzeugen. Solche Messeinrichtungen sind für Trommelfilter an sich bekannt. Das Wasser, das bei der Filterausspülung verwendet wird, kann in kleiner Menge unter hohem Druck eingesetzt werden, so dass Abwasser mit hoher Schmutzkonzentration, aber eben in relativ geringer Menge anfällt.In a first embodiment, the drum filter includes a wash water inlet and a wash water drain over which the wash water cycle passes, and a dirty water drain not included in the cycle. Preferably, the drum filter is then in the washing water circuit from the drum interior to the drum environment, ie from the inside to the outside through-flowing drum filter, which allows a simple automatic cleaning rinse. For automatic cleaning rinse comprises the plant according to an expedient embodiment, a control unit that controls the filter cleaning a reversing water circuit on the drum filter valve and the Zulaufschichtfläche the filter with the dirty water drain valve connecting, in which case the rinsing is done by previously purified wash water; or comprises a control unit which controls a valve which opens the washing water circuit on the drum filter, a valve opening a fresh water inlet to the inlet layer surface of the filter, and a valve connecting the inlet layer surface of the filter with the dirty water outlet for filter cleaning. With the help of the control unit, the filter rinse is carried out automatically, either by a timing of valve actuation for filter cleaning, ie at predetermined intervals, or by a measuring device for measuring the filter contamination, the measurement signal is fed to the control unit for controlling the filter cleaning. The measuring device can detect, for example, the back pressure of the filter, the backwater level of the wash water upstream of the filter or the water level in a collection chamber behind the filter and thereby generate the signal for the maturity of a filter backwash. Such measuring devices are known per se for drum filters. The water that is used in the filter rinse, can be used in small quantities under high pressure, so that sewage with high dirt concentration, but in relatively small amount is obtained.
Der Trommelfilter kann aber auch so aufgebaut sein, dass die Filterschicht aus einer Vliesbahn besteht, die von einer Vorratsrolle kommend um einen trommelförmigen Tragkörper und weiter zu einer Aufwickelrolle verläuft und im Bereich des Tragkörpers den Trommelfilter bildet. In diesem Fall wird der Trommelfilter nicht durch Rückspülung, sondern durch Weitertransport der Vliesbahn erneuert, die im verschmutzten Zustand von der Aufwickelrolle gesammelt und erst nach Verbrauch des Vorratsrollen-Vorrats ausgewechselt wird, was nur in längeren Zeitabständen notwendig wird. Die Steuerung des Vliesbahntransports kann durch die Messeinrichtung wie im Fall der Filter-Aus- oder Rückspülung erfolgen. Für die Ausführung mit Vliesbahn ist es vorteilhaft, wenn der Trommelfilter ein im Waschwasser-Kreislauf von der Trommelumgebung zum Trommelinneren, also von außen nach innen durchflossener Trommelfilter ist, da sich auf der Vliesbahn-Innenseite der trommelförmige Tragkörper befindet, der andernfalls mit dem Filterkuchen kollidieren würde. Vorzugsweise ist die Anlage mit einer Steuereinheit ausgestattet, die zum Weitertransport der Vliesbahn auf dem Tragkörper zwecks Filtererneuerung einen Antrieb der Aufwickelrolle ansteuert.But the drum filter can also be constructed so that the filter layer consists of a nonwoven web, which comes from a supply roll to a drum-shaped support body and on to a take-up roll and forms the drum filter in the region of the support body. In this case, the drum filter is not renewed by backwashing, but by further transport of the nonwoven web, which is collected in the dirty state of the take-up reel and replaced only after consumption of the supply roll stock, which is necessary only at longer intervals. The control of the nonwoven web transport can be done by the measuring device as in the case of filter off or backwash. For the embodiment with nonwoven web, it is advantageous if the drum filter is a drum filter in the washing water circuit from the drum environment to the inside of the drum, ie from outside to inside, since the drum-shaped support body is located on the nonwoven web inside, which otherwise collides with the filter cake would. Preferably, the system is equipped with a control unit, which drives a drive of the take-up roll for further transport of the nonwoven web on the support body for the purpose of filter replacement.
