Abstract

It is known to combat pests, e.g. bacteria, viruses or fungi, which have settled on surfaces, by spraying on chemical agents. However, this type of pest control results in the development of pest strains which as the years go by become resistant against said chemical agents. In order nevertheless to eliminate these pests it is proposed, according to the invention, that very small surface areas be exposed successively to several thousand mm vacuum and treated by rinsing with air and/or water in the vacuum region on the suction surface, the carrier and surface-rinsing medium being air or a mixture of water or air and water, which is sucked off by a high-power generator, preferably a vacuum pump, and the surface itself be exposed to a vapour jet, an air jet or a combined water/air or water/air/vapour jet. The treated surface is sucked off immediately via the high-power vacuum pump, the surface itself being treated, depending on the severity of the pest infestation, with an electron beam and/or, depending on the type of pest, by ultra radiation, and the suction device, e.g. a water ring pump, which is also equipped with ultrasound and UV radiation units, separates off the emergent air through bactericidal chemisorption filters into the space or via a hose into the open air.

Description

Beschreibung und Erläuterung zur PatentanmeldungDescription and explanation of the patent application

"Verfahren zur Behandlung von Flächen, die von Bakterien und/oder Pilzen usw. befallen sind."Process for the treatment of surfaces caused by bacteria and / or Fungi etc. are infested.

Bakterien, Viren, Pilze usw. halten sich vielfach an porösen Flächen, an den Fliesen, im Holz und/ oder in den Fugen und Wandverkleidungen von Räumen fest.Bacteria, viruses, fungi, etc. often stick to porous surfaces, on the tiles, in the wood and / or in the joints and wall coverings of rooms fixed.

Das Aufsprühen chemischer Mittel zur Bekämpfung dieser Schädlinge ist allgemein bekannt.The spraying of chemical means to control these pests is well known.

Jedoch entwickeln sich Schädlings-Stämme, die im Laufe der Jahre resistent gegen entsprechende chemische Beaufschlagungen werden.However, pest strains develop that become resistant over the years against appropriate chemical exposure.

Die chemischen Bekämpfungamittel bilden natürlich auch eine allgemeine Gefahr für den Menschen und das Tier sowie für die Pflanzen, die sich in unmittelbarer Nähe der behandelten Flächen aufhalten oder sogar damit in Berührung kommen.The chemical control agents form naturally even a general danger to humans and animals as well as to the plants that stay in the immediate vicinity of the treated areas or even in Come into contact.

Um die Flächen vom Befall gesäubert zu bekommen, wird erfindungsgem.Rß vorgeschlagen, Rochleistungs-Vakuum-Pumpen zur Flächenabsaugung zu benutzen.In order to get the surfaces cleaned of infestation, according to the invention, Rß proposed to use high-performance vacuum pumps for surface suction.

Der Einsatz von Staubsaugern reicht zur Flächenabsaugung keinesfalls aus, da er nur eine Saugleistung von kleiner 1.500 mm WS aufweist.The use of vacuum cleaners is by no means sufficient for area suction because it only has a suction power of less than 1,500 mm water column.

Zur Bekämpfung der befallenen Flächen benötigt man keine Staubsauger, sondern erfindungsgemäß Hochleistungsvakuumpumpen, die vorzugsweise als Wasserringpumpen ausgebildet sind und mehrere Tausend mm Unterdruck erzeugen, so daß die Flächen mit einer Hochleistungsvakuumsaugdüse erfaßt werden ,und die abgesaugten Schädlinge durch die Flüssigkeit der Hochleistungsvakuufflpumpe gesaugt und gefördert werden und in der Flüssigkeit, die entsprechend chemisch präpariert ist, getötet werden.You do not need a vacuum cleaner to combat the infested areas, but according to the invention high-performance vacuum pumps, preferably as water ring pumps are designed and generate several thousand mm of negative pressure, so that the surfaces can be detected with a high-performance vacuum suction nozzle, and the sucked off pests be sucked and conveyed by the liquid of the high-performance vacuum pump and be killed in the liquid, which is chemically prepared accordingly.

Um den Effekt der Absaugung und der Tötung der Schädlinge max. zu gestalten, wird erfindungsgemäß vorgeschlagen, die Hochleistungsvakuumsaugdüse mit Ultraschall und/oder Elektronenstrahl-Ausrüstung zu kombinieren.In order to maximize the effect of the suction and the killing of the pests design, it is proposed according to the invention to use the high-performance vacuum suction nozzle Combine ultrasound and / or electron beam equipment.

Hierdurch werden die Flächen nicht nur hochleistungs mäßig über Vakuumpumpen abgesaugt, sondern anhaftende Pilze usw. werden durch eine intensive Strahlung geschwächt und/oder getötet und durch Ultraschall zusätzlich geschwächt und/oder getötet und durch die Hochleistungsvakuumabsaugung in den Bereich der chemischen Waschflüssigkeit hineingesaugt und hier weiterhin durch UV-Bestrahlungen und/oder Ultraschall der letzten Behandlungsstufe unterworfen.This means that the surfaces are not only high-performance using vacuum pumps sucked off, but adhering fungi etc. are weakened by intense radiation and / or killed and additionally weakened and / or killed and by ultrasound through the high-performance vacuum suction in the area of the chemical washing liquid sucked in and here continued by UV irradiation and / or ultrasound of the subjected to the last stage of treatment.

Zur weiteren Sicherung der austretenden Absaugluft gegen Schädlingsausstoß wird erfindungsgemäß vorgeschlagen, dem Vakuumerzeuger - vorzugsweise Wasser-Ring-Pumpe - eine bakterizide Ghemisorptionsfilterstufe nachzuschalten, die aus UV-bestrahlten Luftkanälen und Aktivkohle sowie Natronkalk und anderen Schüttstoffen und Filterflächen besteht, die 1. einen Tronfendurchriss aus dem Wasser-Ring vermeiden und 2. eine weitere Sicherung gegen Schädlingsdurchriss garantieren.To further secure the exiting suction air against pest emissions is proposed according to the invention, the vacuum generator - preferably Water ring pump - a bactericidal Ghemisorptionsfilterstufe connected downstream that from UV-irradiated air ducts and activated carbon as well as soda lime and other bulk materials and filter surfaces, which 1. prevent a drip tear from the water ring and 2. guarantee further protection against pest penetration.

Die gesamte Vorrichtung zur Behandlung von bakterienbefallenen Flächen ist mit einer Meß- und Regeltechnik ausgeführt, die es erlaubt, vorzugsweise über Sensoren gesteuert die Belastung der Luft und/oder der medien, die an dem Prozeß teilnehmen, meßtechnisch kenntlich zu machen - so z.B. Flüssigkeit in der Abluft mit grün kenntlich gemacht, bedeutet gleich "saurer" und mit rot bedeutet gleich "belastend" und muß ausgetauscht werden.The entire device for the treatment of surfaces infected with bacteria is carried out with a measurement and control technology that allows, preferably over Sensors controlled the load on the air and / or the media involved in the process participate, to make it identifiable by measurement - e.g. liquid in the exhaust air Marked with green, means "sour" and with red means the same "Onerous" and needs to be replaced.

In der beiliegenden zeichnung ist die Vorrichtung zur Durchführung des Verfahrens dargestellt: mit (1) eine befallene z.B. Sauna- oder Duschwaschzellenwand; mit (2) die Hochleistungsvakuumdüse, die vorzugsweise mit Ultraschall und/oder Elektronenstrahl sendern bzw. Vorrichtungen ausgebildet ist; mit (3) die Hochleistungsvakuumstation, vorzugsweise als Wasser-Ring-Pumpe ausgebildet, die mit Ultraschall- und UV-Bestrahlungseinrichtungen armiert ist; mit (4) das Saugmundstück; mit (5) die Saugleitung; mit (6) die Mediumleitung; mit (7) die Hochleistungspumpe; mit (8) der Chemisorptionsfilter; mit (9) die Schlauchleitung; mit (10) das Fahrwerk.In the accompanying drawing is the device for implementation of the procedure: with (1) an infested, e.g. sauna or shower cubicle wall; with (2) the high-performance vacuum nozzle, which is preferably ultrasound and / or electron beam transmitters or devices is formed; with (3) the high-performance vacuum station, preferably designed as a water ring pump with ultrasonic and UV irradiation devices is armored; with (4) the suction nozzle; with (5) the suction line; with (6) the medium line; with (7) the high-performance pump; with (8) the chemisorption filter; with (9) the hose line; with (10) the landing gear.
