Description
<Desc/Clms Page number 1>
Die Erfindung bezieht sich auf ein Verfahren zur Gewinnung von Gasen, die leichter als Luft sind, insbesondere Biogas, Methangas, sowie Treibstoff-Dämpfe.
Ausgehend von der Tatsache, dass nach wie vor Ozon-zerstörende Gase ungehindert in die Atmosphäre entweichen können, verhindert die vorliegende Erfindung teilweise oder zur Gänze diesen Prozess und leistet damit einen Beitrag zur Bewahrung der Natur und zur Schonung der menschlichen Gesundheit. Darüber hinaus ermöglicht sie eine umweltschonendere Rückführung des gewonnenen Gases in den Stoffkreislauf. Eines der Gase, das hauptsächlich an der Zerstörung der Ozonschicht der Erde beteiligt ist, das Methangas, welches im Zuge des Verdauungsprozesses von Säugetieren entsteht, kann durch das vorliegende Verfahren am ungehinderten Entweichen in die Atmosphäre gehindert werden. Darüberhinaus kann es den Tieren auf umweltschonende Weise im Winter wieder als Wärmeenergieträger zu Gute kommen.
Ebenso kann damit v. a. in Tankstellen in geschlossener Bauweise das Entweichen Ozonzerstörender Gase verhindert werden. Beim vorliegenden Verfahren wird nicht unbedingt Gärsubstrat, Gülle od. andere Ausscheidungsprodukte gesammelt und einer Biogas-Anlage zugeführt, sondern es wird - ähnlich der Gaspendelleitungen bei Tankstellen - das Entweichen des aufsteigenden Gases sogleich nach dem Auftreten dadurch verhindert, dass der Umstand genützt wird, dass das jeweilige Gas leichter als Luft ist, aufsteigt und aufgefangen werden kann.
Die Aufgabe wird gelöst durch ein Verfahren, in dem das Gas, welches leichter als Luft ist, in eine Auffangvorrichtung aufsteigt, von einem od. mehreren Gas-Sensor/en erkannt wird, worauf z. B. ein Ventil und/oder eine Pumpe so geregelt wird, dass das Gas weiter strömt oder gepumpt wird und über eine Gasleitung der weiteren Verwertung zugeführt wird.
Besonders vorteilhaft ist dabei die Verwendung einer Pumpe und/oder eines Ventils, die/das durch mindestens 2 Gas-Sensoren od. Sensorengruppen gesteuert wird, wobei bei Registrierung von Gas durch den/die untere/n und obere/n Sensor/gruppe z. B. ein Ventil und/oder eine Pumpe so geregelt wird, dass das Gas weiter strömt oder gepumpt wird und bei Nicht-Registrierung von Gas durch den/die obere/n Sensor/gruppe dieser Vorgang angehalten wird.
Die Vorrichtung zur Durchführung d. Verfahrens umfasst die Bestückung mit einem Brenner zur Energiegewinnung, mit einer Druckflasche zur Speicherung des Gases, mit Filtern zur Filterung von Verunreinigungen, einem Druckmesser mit Überdruck-Ableitungs-Möglichkeit für erhöhte Sicherheit, sowie einer Steuerung, welche ihrerseits durch die Gas-Sensoren gesteuert wird, und bei Feststellung von bestimmten Gas-Konzentrationen die Pumpe od. das Ventil steuert.
In der beigelegten Zeichnung (Abb. 1) ist eine beispielsweise Ausführung des Erfindungsgegenstandes ersichtlich. Das Gas (1), das leichter als Luft ist, z. B. Biogas, Methangas od. TreibstoffDämpfe, steigt z. B. in einem Kuhstall oder in einer Tankstelle auf. Ein od. mehrere Gas-Sensoren (3) (7) registrieren den Gassee, der sich in der Auffangvorrichtung (2) bildet. Diese kann trichterförmig ausgeführt sein. Der Trichter kann beispielsweise an der Decke (6) des Stalles od. der Tankstelle montiert sein. Der Gas-Sensor od. die Gas-Sensoren steuern eine Gerätschaft (4), welche z. B. eine Pumpe und/od, ein Ventil sein kann. Im Fall einer Pumpe wird diese bei Registrierung von Gas durch den/die Sensoren eingeschaltet und pumpt das Gas über eine Gasleitung (5) z. B. in eine Druckflasche (10) ab.
Im Fall eines Ventils wird dieses geöffnet, und das Gas strömt hindurch, um beispielsweise über eine Zuleitung (5) einem Gasbrenner (11) zugeführt zu werden.
Wenn kein Gas mehr durch den/die Sensoren registriert wird, wird der Vorgang angehalten solange, bis sich wieder in ausreichender Menge das jeweilige Gas angesammelt hat. Der Kreislauf beginnt von neuem. Durch die Verwendung von Steuerungsapparaturen, die verschiedene Sensorrückmeldungen auswerten können und/oder in der Höhe variierender Anordnung von mehrereren Gas-Sensoren, kann die Effizienz des Verfahrens gesteigert werden. So kann durch mindestens 2 in verschiedenen Höhen angebrachte Sensoren das Volumen des Gassees und die Dauer für einen Abpumpvorgang eingestellt werden. Auch durch die Verwendung von GasSensoren, die sowohl das Vorhanden-sein sowie die Konzentration eines od. mehrerer Gase feststellen können, kann die Effizienz gesteigert werden. Wenn als Entstehungsort des Gases ein Tierstall herangezogen wird, kann unter Verwendung evtl.
Speicherungs-Druckflaschen der selbe Stall im Winter beheitzt werden, um so einen umweltfreundlichen Stoffkreislauf zu initiieren. Die Krümmung, Wandstärke und der Durchmesser der verwendeten Materialien sind in der Abbildung nur zu Illustrationszwecken dargestellt, jedoch nicht massstabsgetreu od. funktionsrelevant.

The invention relates to a method for obtaining gases that are lighter than air, in particular biogas, methane gas, and fuel vapors.
Based on the fact that ozone-depleting gases can still escape unhindered into the atmosphere, the present invention partially or completely prevents this process and thus contributes to the preservation of nature and the protection of human health. In addition, it enables the gas obtained to be returned to the material cycle in a more environmentally friendly manner. One of the gases that is mainly involved in the destruction of the earth's ozone layer, the methane gas that is produced in the course of the digestive process of mammals, can be prevented by the present method from unhindered escape into the atmosphere. In addition, the animals can benefit from heat in an environmentally friendly manner in winter.
Likewise, v. a. in gas stations in a closed construction the escape of ozone-depleting gases can be prevented. In the present process, the fermentation substrate, liquid manure or other waste products are not necessarily collected and fed to a biogas plant, but - similar to the gas exchange lines at petrol stations - the escape of the rising gas is prevented immediately after the occurrence by taking advantage of the fact that the respective gas is lighter than air, rises and can be collected.
The object is achieved by a method in which the gas, which is lighter than air, rises into a collecting device, is recognized by one or more gas sensors. B. a valve and / or a pump is controlled so that the gas continues to flow or pump and is fed via a gas line for further use.
It is particularly advantageous to use a pump and / or a valve which is controlled by at least 2 gas sensors or sensor groups. When gas is registered by the lower and upper sensor / groups, e.g. B. a valve and / or a pump is regulated so that the gas continues to flow or is pumped and if gas is not registered by the / the upper / n sensor / group this process is stopped.
The device for carrying out d. The process includes equipping with a burner for energy generation, with a pressure bottle for storing the gas, with filters for filtering impurities, a pressure meter with the possibility of overpressure discharge for increased safety, and a control system, which in turn is controlled by the gas sensors , and if certain gas concentrations are determined, the pump or the valve is controlled.
The attached drawing (Fig. 1) shows an example of an embodiment of the subject matter of the invention. The gas (1), which is lighter than air, e.g. B. biogas, methane gas or fuel vapors, increases z. B. in a cowshed or in a gas station. One or more gas sensors (3) (7) register the gas lake that forms in the collecting device (2). This can be funnel-shaped. The funnel can, for example, be mounted on the ceiling (6) of the barn or the gas station. The gas sensor or the gas sensors control a device (4) which, for. B. can be a pump and / or a valve. In the case of a pump, this is switched on when the gas is registered by the sensor (s) and pumps the gas via a gas line (5) z. B. in a pressure bottle (10).
In the case of a valve, it is opened and the gas flows through it, for example, to be fed to a gas burner (11) via a feed line (5).
If no more gas is registered by the sensor (s), the process is stopped until the respective gas has accumulated again in sufficient quantity. The cycle begins again. The efficiency of the method can be increased by using control apparatuses which can evaluate different sensor feedback and / or the arrangement of several gas sensors which vary in height. The volume of the alley and the duration of a pumping process can be set using at least 2 sensors at different heights. Efficiency can also be increased by using gas sensors, which can determine both the presence and the concentration of one or more gases. If an animal barn is used as the place of origin of the gas,
Storage pressure bottles of the same barn are heated in winter in order to initiate an environmentally friendly material cycle. The curvature, wall thickness and diameter of the materials used are shown in the illustration only for illustration purposes, but are not to scale or functionally relevant.
