Die Erfindung betrifft ein Verfahren und eine Einrichtung zur Aufbereitung von Brauchwasser, bei dem zur Bekämpfung der darin enthaltenen Mikroorganismen das Wasser auf eine bakterizide Temperatur erhitzt wird.The invention relates to a method and a device for treating industrial water, in which the water is heated to a bactericidal temperature in order to combat the microorganisms contained therein.
Aus dem Lehr- und Handbuch der Abwassertechnik, Band 2,2. Auflage, Berlin, ist auf Seite 562 ff. eine Abwasserbehandlungsanlage bekanntgeworden, bei der von einem Krankenhaus stammendes Abwasser in einem Behälter gesammelt wird. Von diesem Behälter wird es über einen Abfallzerkleinerer abgezogen und teilweise dem oberen Bereich des Speichers wieder zugefügt, andererseits über eine Pumpe in einen Desinfektionswärmetauscher gefördert. Von diesem gelangt das Abwasser in ein Verweilgefäß, von wo es über einen Wärmerückgewinnungs-Wärmetauscher in den Kanal fließt. Der Erfindungsgegenstand befaßt sich mit im Trinkwasser vorhandenen Mikroorganismen, insbesondere die die sogenannte Legionärskrankheit verursachenden Bakterien legionella pneumophila, die zum Absterben gebracht werden müssen.From the teaching and handbook of waste water technology, volume 2.2. Edition, Berlin, on page 562 ff. A wastewater treatment plant has become known, in which wastewater from a hospital is collected in a container. From this container it is drawn off via a waste shredder and partly added back to the upper area of the storage unit, on the other hand it is pumped into a disinfection heat exchanger. From there, the wastewater flows into a retention tank, from where it flows into the sewer via a heat recovery heat exchanger. The subject of the invention is concerned with microorganisms present in drinking water, in particular the legionella pneumophila bacteria which cause the so-called legionnaires' disease and which must be brought to death.
Hierzu müßte das Brauchwasser auf eine Temperatur von 65 bis 70 °C erhitzt und mit dieser Temperatur bis zur Zapfstelle geführt werden.To do this, the process water would have to be heated to a temperature of 65 to 70 ° C and carried at this temperature to the tap.
Befindet sich an der Zapfstelle eine thermostatisch gesteuerte Mischbatterie, ist die Verbreitungsgefahr vergleichsweise gering, doch sind solche Mischbatterien einigermaßen kostspielig.If there is a thermostatically controlled mixer tap at the tap, the risk of spreading is comparatively low, but such mixer taps are reasonably expensive.
Aufgabe der Erfindung ist es, der Verbreitungsgefahr mit geringem Kostenaufwand wirksam vorzubeugen und eine Möglichkeit zu schaffen, auch bereits bestehende Wasserversorgungsanlagen gegen eine Verbreitung solcher Mikroorganismen möglichst weitgehend zu schützen.The object of the invention is to effectively prevent the risk of spreading at low cost and to create a possibility to protect existing water supply systems as far as possible against the spread of such microorganisms.
Erfindungsgemäß wird dem Brauchwasser erst unmittelbar vor seiner Abgabe an den Verbraucher Kaltwasser in einem selbsttätig gesteuerten Anteil beigemischt. Der Durchsatz des zugemischten Kaltwassers kann in Abhängigkeit vom Warmwasserdurchsatz und/oder von der Kaltwassertemperatur bemessen sein. Die erfindungsgemäße Lösung zeichnet sich nicht nur durch einen geringen Kostenaufwand aus, sondern auch dadurch, daß die Auslauftemperatur des gezapften Brauchwassers ohne weiteres Zutun gut konstant gehalten werden kann. Die Gefahr einer Verbreitung der Mikroorganismen wird erheblich reduziert.According to the invention, cold water is added to the process water in an automatically controlled proportion only immediately before it is delivered to the consumer. The throughput of the mixed cold water can be dimensioned depending on the hot water throughput and / or on the cold water temperature. The solution according to the invention is not only characterized by a low cost, but also by the fact that the outlet temperature of the tap water can be kept constant well without further action. The risk of spreading the microorganisms is considerably reduced.
Eine Einrichtung zur Durchführung des Verfahrens umfaßt bevorzugt eine Warmwasserzufuhrleitung, eine Kaltwasserversorgungsleitung und eine von diesen Leitungen gemeinsam gespeiste Zapfstelle. Erfindungsgemäß ist in der Warmwasserzufuhrleitung vor der Zapfstelle ein vom Warmwasserdurchsatz betätigbares Steuerorgan angeordnet, das die Menge des dem Warmwasser aus der Kaltwasserversorgungsleitung zugemischten Kaltwassers steuert. Mit einer solchen Temperaturregelung des Zapfwassers kann diese Temperatur sehr zuverlässig konstant gehalten werden.A device for performing the method preferably comprises a hot water supply line, a cold water supply line and a tap jointly fed by these lines. According to the invention, a control element which can be actuated by the hot water throughput and which controls the amount of cold water mixed with the hot water from the cold water supply line is arranged in the hot water supply line in front of the tap. With such a temperature control of the tap water, this temperature can be kept very reliably constant.
Das Steuerorgan kann in diesem Fall aus einem sogenannten Wasserschalter bestehen, wie er bei Wasserheizem mit Gasbrenner zur Steuerung der Gaszufuhr benutzt wird.In this case, the control element can consist of a so-called water switch, as is used in water heaters with a gas burner to control the gas supply.
Anstelle eines solchen Wasserschalters kann aber auch ein von der Kaltwassertemperatur beeinflußtes Steuerorgan angeordnet werden, das die Menge des dem Warmwasser aus der Kaltwasserversorgungsleitung zugemischten Kaltwassers in Abhängigkeit von dessen Temperatur steuert.Instead of such a water switch, a control element influenced by the cold water temperature can also be arranged, which controls the amount of cold water mixed with the hot water from the cold water supply line depending on its temperature.
Eine weitere Möglichkeit besteht in einer Kombination beiderlei Maßnahmen, wobei dann in der Warmwasserzufuhrleitung ein von derem Durchsatz betätigbares Organ angeordnet ist, dem das Kaltwasser aus der Kaltwasserversorgungsleitung zur Regelung seines Anteiles über einen in der Kaltwasserversorgungsleitung angeordneten Thermostaten zuströmt.A further possibility is a combination of both measures, in which case an organ which can be actuated by its throughput is arranged in the hot water supply line and to which the cold water flows from the cold water supply line to regulate its share via a thermostat arranged in the cold water supply line.
Schließlich empfiehlt es sich noch, die Einrichtung mit einer das Steuerorgan umgehenden und von der Kaltwasserzufuhrleitung ausgehenden, unmittelbar zur Zapfstelle führenden Kaltwasserzweigleitung auszustatten.Finally, it is also advisable to equip the device with a cold water branch line which bypasses the control element and extends from the cold water supply line and leads directly to the tap.
Die beiden Zeichnungsfiguren zeigen beispielsweise je eine Ausführungsform einer erfindungsgemäßen Einrichtung in schematischer Darstellung.The two drawing figures each show, for example, an embodiment of a device according to the invention in a schematic representation.
Gemäß Fig. 1 führen eine Warmwasserzufuhrleitung (1) und eine Kaltwasserversorgungsleitung (2) zu einem Steuerorgan (3), von dem die Zapfleitung (4) zu einer Zapfstelle (5) führt. Diese Zapfstelle (5) steht überdies mit einer Kaltwasserzweigleitung (6) in Verbindung, die das Steuerorgan (3) umgeht.1, a hot water supply line (1) and a cold water supply line (2) lead to a control element (3), from which the tap line (4) leads to a tap (5). This tap (5) is also connected to a cold water branch line (6) which bypasses the control member (3).
Das Steuerorgan (3) kann - wie ein sogenannter Wasserschalter eines brennstoffbeheizten Wasserheizers - vom Durchsatz der Warmwasserzufuhrleitung (1) betätigbar sein, um die Menge des dem mit 65 bis 70 °C zuströmenden Warmwasser aus der Kaltwasserversorgungsleitung (2) mit einer Temperatur von 5 bis 15 °C zugemischten Kaltwassers und damit die Temperatur des an der Zapfstelle (5) auslaufenden Mischwassers zu steuern.The control element (3) - like a so-called water switch of a fuel-heated water heater - can be actuated by the throughput of the hot water supply line (1) in order to control the amount of hot water flowing in at 65 to 70 ° C from the cold water supply line (2) at a temperature of 5 to 15 ° C mixed cold water and thus to control the temperature of the mixed water running out at the tap (5).
Dieses Steuerorgan (3) kann aber im Rahmen der Erfindung auch von der Temperatur des Kaltwassers beeinflußt betätigbar sein und durch einen Thermostaten verkörpert werden.This control member (3) can also be operated within the scope of the invention influenced by the temperature of the cold water and embodied by a thermostat.
In beiden Fällen läßt sich das Steuerorgan (3) auch nachträglich vor der Zapfstelle in ein Leitungssystem einbauen.In both cases, the control element (3) can also be retrofitted in a line system in front of the tap.
Wie Fig. 2 zeigt, lassen sich beiderlei Systeme vorteilhaft miteinander kombinieren, wobei dann in der Warmwasserzufuhrleitung (1) ein durch deren Durchsatz betätigbarer Wasserschalter (7) angeordnet ist, dem das Kaltwasser aus der Kaltwasserversorgungsleitung (2) zur Regelung seines Anteiles über einen Thermostaten (8) zuströmt.As shown in FIG. 2, the two systems can be advantageously combined with one another, in which case a water switch (7) which can be actuated by their throughput is arranged in the hot water supply line (1) and the cold water from the cold water supply line (2) regulates its share via a thermostat (8) flows in.
Auch in diesem Fall kann eine von der Kaltwasserversorgungsleitung (2) ausgehende und unmittelbar zur Zapfstelle (5) führende Kaltwasserzweigleitung (6) das aus dem Wasserschalter (7) und dem Thermostaten (8) kombinierte Steuerorgan (3) umgehen. Wesentlich ist jedenfalls, daß dem auf eine bakterientötende Temperatur erhitzten Warmwasser der an der Zapfstelle (5) erwünschte Kaltwasseranteü erst unmittelbar vor der Abgabe des -2-In this case, too, a cold water branch line (6) starting from the cold water supply line (2) and leading directly to the tap (5) can bypass the control element (3) combined from the water switch (7) and the thermostat (8). In any case, it is essential that the hot water heated to a bactericidal temperature does not produce the cold water desired at the tap (5) until immediately before the -2-
