Laser disinfection tunnel or lock for disinfecting fluids and materials with honeycomb-shaped laser safety grid, characterized by the simultaneous use of several laser beams and/or several wavelengths such as 405nm, 450nm and 2940nm (laser operating mode continuous wave and/or pulsed) matching the absorption spectrum of the through Matter in the solid and liquid state running through the system in combination with superimposed laser radiation due to multiple reflections with very high optical density in wavelengths that are strongly absorbed by the target medium and matter.
Description
Ein Laser-Desinfektions-Tunnel besteht aus einem optisch geschlossenen System in zylindrischer oder kubischer Form, welches mit hochreflektierenden Spiegelflächen bestückt ist und Mehrfachreflexionen von Laserstrahlen zwischen Spiegelebenen auf einer Ebene, nämlich der Strahlebene ermöglicht, wodurch eine hohe optische Energie auf dieser Ebene überlagert wird. Die Strahlebene ist die gemeinsame Fläche bestehend aus der orthogonalen der Spiegel und der Strahlungsrichtung der Laser. Der Laserstrahl wird in dieser Strahlebene aufgeweitet.A laser disinfection tunnel consists of an optically closed system in a cylindrical or cubic form, which is equipped with highly reflective mirror surfaces and allows multiple reflections of laser beams between mirror levels on one level, namely the beam level, whereby a high optical energy is superimposed on this level. The beam plane is the common area consisting of the orthogonal plane of the mirrors and the radiation direction of the lasers. The laser beam is expanded in this beam plane.
Tunnel-Eingang und Tunnel-Ausgang sind parallel zur Strahlebene mit Wabenförmigen Absorbern geschützt. Laserstrahlen ausgehend von Lasern oder Spiegeln können nicht durch diesen wabenförmigen Absorber entweichen.The tunnel entrance and tunnel exit are protected parallel to the beam plane with honeycomb absorbers. Laser beams from lasers or mirrors cannot escape through this honeycomb absorber.
Im System kommt durch einen oder mehrere Laserquellen in Kombination mit Optiken auf Grund von Mehrfachreflexionen zwischen den Spiegeln eine hohe optische Photonendichte zustande.In the system, one or more laser sources in combination with optics result in a high optical photon density due to multiple reflections between the mirrors.
Durch Photon-Materie-Wechselwirkung kann zu aller durch dieses System laufender Materie gezielt Energie zugefügt werden. Die Auswahl von Laserquellen und dazu gehörigen Wellenlängen ist abhängig vom jeweiligen Prozess und der Applikation. Zweck Desinfektion werden die Laserquellen nach spezifischen Absorptionsmaxima der zu behandelnden Materie gewählt. Desinfektion und Neutralisierung der Mikroorganismen wird durch Wärmeaufnahme und die Denaturierung von Proteinen in Membranzellen hervorgerufen. Auf diesem Weg können Mikroorganismen Foto-chemisch und/oder Foto-mechanisch umgesetzt, bzw. modifiziert und abgetötet werden.Through photon-matter interaction, energy can be selectively added to all matter moving through this system. The selection of laser sources and the associated wavelengths depends on the respective process and application. For the purpose of disinfection, the laser sources are selected according to the specific absorption maxima of the material to be treated. Disinfection and neutralization of the microorganisms is brought about by absorption of heat and denaturation of proteins in membrane cells. In this way, microorganisms can be converted photo-chemically and/or photo-mechanically, or modified and killed.
Das System besteht aus (1) Hochreflektierende Metallische Rahmen oder Spiegel mit energiereichen Mehrwellenlängen Laserquellen (2) welche insbesondere die Wellenlängen passend zum Absorptionsspektrum der zu behandelnden Materie abdeckt.The system consists of (1) Highly reflective metallic frames or mirrors with high-energy multi-wavelength laser sources (2) which in particular covers the wavelengths matching the absorption spectrum of the material to be treated.
In kubischen Anordnungen wie in einem rechteckigen oder quadratischen Rahmen sind die Laserquellen in Ecken positioniert und die Strahlen entlang der Diagonale, wobei die Laserstrahlen nur in eine Richtung entlang der Diagonalen unter einem Winkel größer als 90 Grad aufgeweitet sind. In zylindrischer Anordnung wie in einen Zylinder strahlen die Laserquellen unter einen Winkel zum Durchmesser oder Parallel zum Durchmesser und nicht radial. Der Laserstrahl wird mit Optiken unter einem Winkel größer als 90 Grad in Strahlebene aufgeweitet. Das System ist mit (3) Wabenförmige Laserschutzgitter als optische Falle zweck Schutz gegen Austritt von Laserstrahlen bestückt. Hauptanwendungsfall ist Desinfektion und Entkeimung von Luft (Gas), Wasser (Flüssigkeit) oder Materialoberflächen (Festkörper) sowie Lebensmittel.In cubic arrays, such as in a rectangular or square frame, the laser sources are positioned in corners and the beams along the diagonal, with the laser beams being flared in only one direction along the diagonal at an angle greater than 90 degrees. In a cylindrical arrangement such as in a cylinder, the laser sources radiate at an angle to the diameter or parallel to the diameter and not radially. The laser beam is expanded with optics at an angle greater than 90 degrees in the beam plane. The system is equipped with (3) honeycomb laser protection grids as an optical trap for the purpose of protection against leakage of laser beams. The main application is the disinfection and sterilization of air (gas), water (liquid) or material surfaces (solids) and food.
Hauptanwendungsfall ist die Desinfektion und Entkeimung von Gasen wie Luft, Flüssigkeiten wie Wasser, oder Festkörpern wie Lebensmitteln.The main application is the disinfection and sterilization of gases such as air, liquids such as water, or solids such as food.
Die Wirkung dieses Systems hängt von der Größe, der Durchlaufgeschwindigkeit, dem Strahldurchmesser sowie der Photonendichte ab.The effect of this system depends on the size, the throughput speed, the beam diameter and the photon density.
