Description
Verfahren zur Bekämpfung der Unsichtigkeit bei Nebel. Den Gegenstand der Erfindung bildet ein Verfahren zur Bekämpfung der Unsichtigkeit bei Nebel, das sich von den bekannten in dieser Richtung schon gemachten Vorschlägen dadurch unterscheidet, daß nicht der Nebel beseitigt, sondern in ihm nur ein durchsichtiger Luftstrahl geschaffen werden soll, so-daß das Verfahren auch auf Schiffen, die sich in Fahrt befinden, mit Vorteil wird Verwendung finden können.Method of combating obscurity in fog. The subject of the invention provides a method for combating opacity in fog, the differs from the known proposals already made in this direction in that that it is not the fog that removes it, but only a transparent jet of air in it should be created so that the procedure can also be used on ships that are in motion can be used to advantage.
Gemäß der Erfindung wird bei nebeliger Luft eine gewisse Luftmenge aus der Atmosphäre angesaugt und in einem Gebläse verdichtet. Dabei nimmt infolge ihres Widerstandes gegen die Druckerhöhung ihre Temperatur mehr zu als bei adiabatischer Verdichtung. Läßt man @ dann die Druckluft in einer Düse adiabatisch sich entspannen, so setzt sich die Druckenergie fast verlustlos in Geschwindigkeitsenergie um. Die Luft kühlt sich dabei wohl der adiabatischen Entspannung entsprechend ab, aber ihre Temperatur ist. trotzdem höher als beim Ansaugen. Bei ensprechend gewählten Drucken, Verdichtungs- und Entspannungsverhältnissen' entströmt die Luft vollkommen klär und durchsichtig mit großer Geschwindigkeit der Düse. Es isst dann ein gewisser Luftweg erforderlich., bis die Geschwindigkeit -durch Reibung an der ruhenden Atmosphäre aufgezehrt ist. Bis dahin reicht dann das Auge des Seemanns, und er kann etwa. auftretenden Ge--fahren begegnen.According to the invention, there is a certain amount of air in foggy air sucked in from the atmosphere and compressed in a fan. It takes as a result their resistance to the pressure increase increases their temperature more than with adiabatic Compression. If @ then the compressed air is allowed to relax adiabatically in a nozzle, so the pressure energy is converted into speed energy with almost no loss. the Air cools down according to adiabatic relaxation, but hers Temperature is. still higher than when sucking in. With appropriately selected prints, Compression and relaxation conditions' the air flows out completely clear and transparent with great speed of the nozzle. Then a certain one eats Airway required. Until the speed - by friction with the still atmosphere is consumed. Until then, the sailor's eye can reach, and he can do something about it. occurring Meeting dangers.
Die Wirkung kann noch- erhöht werden :durch Einschaltung einer Luftheizung vor, während oder nach der Verdichtung oder durch Rückströmen eines Teiles der verdichteten Luft durch eine Drosselvorrichtung in die Saugleitung.The effect can be increased: by switching on an air heater before, during or after the compression or by backflow of part of the compressed Air through a throttle device into the suction line.
