Beschreibung: Title: Self-sufficient domestic water disinfection system
Description:
?· Trinkwasser ist in vielen Ländern ein kostbares Nahrungsmittel mit welchem sehr sorgsam umgegangen werden muß. Die Ressource Trinkwasser ist in vielen Bereichen bereits knapp geworden. Es wird daher in diesen geographischen Bereichen und auch zunehmend in Deutschland das Regenwasser in Zisternen gesammelt und als Brauch- und Trinkwasser verwendet. Die Verwendung als Trinkwasser ist jedoch durch die Vermehrung von Mikroorganismen stark eingeschränkt bzw. ohne weitere Behandlung nicht möglich. Ziel der vorliegenden Anlage ist es, eine Desinfektion dieses Wassers vorzunehmen. Es gibt hierzu vier etablierte Standardverfahren: Ozonisierung, Chlorierung, UV-Bestrahlung und Sterilfiltration. Die Ozonisierung und die Sterilfiltration scheiden aufgrund des hohen technischen Anspruches tür die praktische Realisierung bei den meisten Aufgabenstellungen aus (die Ozonisierung wegen des hohen Strombedarfes, der notwendigen Pumpen, der Lufttrocknung u.a.; die Sterilfiltration wegen der Hochdruckpumpe und des häufig nötigen Filterwechsels). ? · In many countries, drinking water is a precious foodstuff which must be handled very carefully. The resource of drinking water has already become scarce in many areas. In these geographical areas, and increasingly in Germany, rainwater is therefore collected in cisterns and used as industrial and drinking water. However, its use as drinking water is severely restricted by the proliferation of microorganisms or is not possible without further treatment. The aim of this system is to disinfect this water. There are four established standard processes for this: ozonation, chlorination, UV radiation and sterile filtration. Ozonation and sterile filtration are not practical for most tasks due to the high technical demands (ozonation because of the high power consumption, the necessary pumps, air drying, etc.; sterile filtration because of the high pressure pump and the frequent need to change filters).
Die UV-Bestrahlung kann zur Wasserdesinfektion eingesetzt werden hat aber folgende prinzipielle Nachteile: 1. Vorhandene kleine Partikel, an die sich Keime gerne anlagern sind durch diese von der UV-Strahlung geschützt. 2. Die Desinfektion erstreckt sich nicht auf das Leitungssystem nach dem UV-Reaktor, so daß hier - besonders in wärmeren Gegenden - wieder eine starke Keimzunahme stattfindet. Die Verkeimung steigt mit zunehmender Länge des LeitungssystemsUV radiation can be used to disinfect water but has the following basic disadvantages: 1. Small particles that germs tend to attach to are protected from UV radiation by these. 2. Disinfection does not extend to the pipe system after the UV reactor, so that here - especially in warmer areas - there is a strong increase in germs. The contamination increases with the length of the pipe system
insgesamt und zunehmender Menge von Strömungsruhezonen (unbenutzte Stichleitungen) an.overall and increasing number of flow rest zones (unused branch lines).
Die Chlorierung besitzt diese Nachteile nicht, ist aber in der bisherigen Einsatzform an Druckgasflaschen oder spezielle Reagentien gebunden. Im letztgenannten Fall wird das Chlor durch eine chemische Reaktion hergestellt. Neu an dem hier vorgelegten Konzept sind die folgenden Charakteristika: Die Hauswasserdesinfektionsanlage besteht in der Hauptsache aus einem Herstellungsraum (2) und einem Chlorvorrats- und -reaktionsraum (3). Die Hauswasserdesinfektionsanlage wird mit einer kleinen Photovoltaikeinheit (4) mit Strom versorgt. Als Ausgangssubstanz für die Chlorherstellung dient das ubiquitär verfügbare Kochsalz, aus welchem auf elektrochemischem Wege vor Ort das benötigte Chlor in der jeweils erforderlichen Menge hergestellt wird. Der Herstellungsraum ist in mehrere Elektrolysezellen (5) aufgeteilt, die kommunizierend miteinander verbunden sind (6) und deren Kathodenseiten einen Ausgleichsraum (7) besitzen. Aus dem Chlorherstellungsgefäß strömt das Chlorgas in ein Steuerrohr (29) und in das Bevorratungsgefäß (3). Das Bevorratungsgefäß ist auch gleichzeitig Reaktionsraum, in dem ein Teilstrom (13,14) des zu desinfizierenden Wassers mit Chlor gesättigt wird (15). Die Wasserzufuhr zu diesem Reaktionsraum wird durch einen Schwimmer (16) geregelt. Über den gleichen Schwimmer (16) wird der Wasserteilstrom auf Lochbleche (17) verteilt unter denen sich zur Oberflächenvergrößerung Füllkörper (18) befinden. Aus diesem Chlorvorrats- und reaktionsraum wird das chlorgesättigte Wasser (15) dem übrigen Wasserstrom (19) zur Entnahme bis zur Einstellung der gewünschten Konzentration zugemischt. Dies geschieht in einer Mischkammer (20). Der Zulauf der chlorgesättigten Wassers und des restlichen Wassers geschieht über einen Schwimmer (21), der über eine druckfedergelagerteChlorination does not have these disadvantages, but in its current form of use it is tied to compressed gas cylinders or special reagents. In the latter case, the chlorine is produced by a chemical reaction. The following characteristics are new in the concept presented here: The domestic water disinfection system consists mainly of a production room (2) and a chlorine storage and reaction room (3). The domestic water disinfection system is supplied with electricity by a small photovoltaic unit (4). The starting substance for chlorine production is the ubiquitously available table salt, from which the required chlorine is produced on site in the required amount by electrochemical means. The production room is divided into several electrolysis cells (5) that are connected to one another in a communicating manner (6) and whose cathode sides have an equalization chamber (7). The chlorine gas flows from the chlorine production vessel into a control pipe (29) and into the storage vessel (3). The storage vessel is also a reaction chamber in which a partial flow (13, 14) of the water to be disinfected is saturated with chlorine (15). The water supply to this reaction chamber is regulated by a float (16). The water partial flow is distributed via the same float (16) to perforated plates (17) under which there are packing elements (18) to increase the surface area. From this chlorine storage and reaction chamber, the chlorine-saturated water (15) is mixed with the remaining water flow (19) for withdrawal until the desired concentration is achieved. This takes place in a mixing chamber (20). The chlorine-saturated water and the remaining water are fed in via a float (21) which is mounted on a pressure spring.
Rolle (22) beide Zuläufe gleichzeitig öffnet oder verschließt. Bei Wasserentnahme aus dem Regenwasserspeicher wird somit immer gleichzeitig die passende Menge chlorgesättigten Wassers zudosiert, so daß die Chlorkonzentration des erhaltenen Wassers immer im gewünschten Bereich liegt. Wenn der Regenwassersammelbehälter (28) oberhalb der Wasserentnahmestelle liegt, sind für den Betrieb der Chlorierungsanlage keine Flüssigkeitspumpen und keine elektronische Steuerung erforderlich. Die Elektroden in der elektrochemischen Chlorierungsanlage sind so angeordnet, daß eine Selbstregulierung der Chlorherstellung ausschließlich mit hydrodynamischen Mitteln und damit eine eigensichere Herstellung erfolgt. Unter eigensicher ist hierbei zu verstehen, daß die Anlage auch ohne eine elektrische Steuerung voll funktionsfähig bleibt und ihre Produktion durch ihre Geometrie und die Wasserentnahme reguliert wird. Die Regelung erfolgt mit Hilfe eines Steuerrohres (29), zweier Ableitrohre aus dem Kathoden- (12) bzw. dem Anodenraum (11) und eines Chlorbegrenzungsventils mit Rückschlagventil (30) in einem der beiden Ableitrohre.Roller (22) opens or closes both inlets at the same time. When water is taken from the rainwater tank, the right amount of chlorine-saturated water is always added at the same time, so that the chlorine concentration of the water obtained is always in the desired range. If the rainwater collection tank (28) is located above the water extraction point, no liquid pumps or electronic control are required to operate the chlorination system. The electrodes in the electrochemical chlorination system are arranged in such a way that self-regulation of chlorine production takes place exclusively with hydrodynamic means and thus intrinsically safe production. Intrinsically safe means here means that the system remains fully functional even without an electrical control and its production is regulated by its geometry and the water extraction. The control is carried out using a control pipe (29), two discharge pipes from the cathode (12) and anode chamber (11) and a chlorine limiting valve with check valve (30) in one of the two discharge pipes.
Bei Zisternen bzw. Wasserspeichern (28), die sich unterhalb der Wasserentnahmestelle befinden (z.B. unter Erdgleiche) erfolgt die Selbstregulierung vor der notwendigen Druckerhöhungspumpe. Durch den Wegfall von elektronischen Steuerungen und zusätzlichen aktiven mechanischen Komponenten (Pumpen) ist die Anlage weitgehendst eigensicher und kann deshalb besonders vorteilhaft in abgelegenen Gebieten ohne zentrale Strom- und Wasserversorgung eingesetzt werden. Durch das Chlorvorratsgefäß ist eine ausreichende Pufferkapazität auch bei mangelnder Sonneneinstrahlung über einen längeren Zeitraum gegeben.In the case of cisterns or water tanks (28) that are located below the water extraction point (e.g. below ground level), the self-regulation takes place before the necessary pressure booster pump. Due to the elimination of electronic controls and additional active mechanical components (pumps), the system is largely intrinsically safe and can therefore be used particularly advantageously in remote areas without central power and water supplies. The chlorine storage tank ensures sufficient buffer capacity even when there is insufficient sunlight over a longer period of time.
Die Druckdifferenz zwischen dem Chlor im Chlorvorrats- und Reaktionsgefäß und dem Atmosphärendruck übersteigt nicht 0,5 bar und unterliegt somit nicht der Druckbehälterverordnung.The pressure difference between the chlorine in the chlorine storage and reaction vessel and the atmospheric pressure does not exceed 0.5 bar and is therefore not subject to the Pressure Vessel Ordinance.
