Abstract
Description
Die vorliegende Erfindung betrifft ein Verfahren nach Oberbegriff des Anspruchs 1 und eine Vorrichtung zur Durchführung des Verfahrens nach Oberbegriff von Anspruch 10.The The present invention relates to a method according to the preamble of Claim 1 and an apparatus for performing the method according to the preamble of claim 10.
Grundlage für den rechtssicheren Betrieb von raumlufttechnischen Anlagen ist eine regelmäßige Wartung, gerade auch im Hinblick auf das Brandrisiko von fettbelasteten Fettabluftkanälen.basis for the legally compliant operation of ventilation and air conditioning systems is one regular maintenance, especially with regard to the fire risk of fat-laden fat exhaust ducts.
Verfahren zur Reinigung solcher Kanalsysteme sind bekannt. Beispielsweise das Strahlen mit Trockeneis, bei dem ein Strahlmittel (in dem Fall Trockeneis) mittels Luftstrom von innen auf die Kanalwände geschossen wird. Nachteilig bei diesem Verfahren ist, dass ein hoher technischer Aufwand nötig ist, dass die Kosten der Trockeneispellets zu berücksichtigen sind und die Arbeitsgeschwindigkeit relativ gering ist.method for cleaning such channel systems are known. For example blasting with dry ice, in which a blasting agent (in the case Dry ice) by means of air flow from the inside shot on the channel walls becomes. The disadvantage of this method is that a high technical Effort is needed that the costs of the dry ice pellets are to be considered and the working speed is relatively low.
Auch Verfahren ohne Strahlmittel sind bekannt, beispielsweise mit Trockendampf. Bei diesem Verfahren wird ein speziell aufbereiteter extrem trockener Dampf mit hoher Temperatur in das Kanalsystem eingeleitet, welches vorher mit einem Spezial-Reinigungsmittel vorbereitet wurde. Nachteilig bei diesem Verfahren ist, dass ebenfalls ein hoher technischer Aufwand nötig ist und dieses Verfahren nicht völlig ohne chemische Hilfsmittel auskommt.Also Methods without blasting agents are known, for example with dry steam. This process is a specially prepared extremely dry High temperature steam introduced into the duct system, which previously prepared with a special detergent. adversely In this method is that also a high technical effort is necessary and this procedure is not complete works without chemical aids.
Dem gegenüber besteht die Aufgabe der vorliegenden Erfindung darin, ein Verfahren anzugeben und eine dafür geeignete Vorrichtung, mit dessen/deren Hilfe die Reinigung eines Kanalsystems von Klima- und Fettabluftkanälen einen schnellen effektiven Reinigungseffekt ohne größeren technischen Aufwand aufweist und dabei umweltschonend ohne agressive Chemikalien wirkt.the across from the object of the present invention is a method specify and one for it suitable device, with the help of which the cleaning of a Channel system of air and fat exhaust ducts a fast effective cleaning effect without major technical Expense and environmentally friendly without aggressive chemicals acts.
Diese Aufgabe wird durch die Merkmale des Anspruchs 1 und des Anspruchs 10 gelöst.These The object is achieved by the features of claim 1 and claim 10 solved.
Von wesentlicher Bedeutung ist es, dass ein trockenes Strahlmittel von ungleichmäßig stochastisch geformten Granulatteilchen mittels eines Düsenkopfes gegen die Innenwandungen des Kanalsystems unter gleichzeitiger Bewegung des Düsenkopfes in Längsrichtung zum Kanalsystem und zugleich erfolgender Rotation der Austrittsöffnung des Düsenkopfes geschleudert wird.From It is essential that a dry abrasive of unevenly stochastic shaped granules by means of a nozzle head against the inner walls of the duct system with simultaneous movement of the nozzle head longitudinal to the channel system and at the same time successful rotation of the outlet opening of the nozzle head is thrown.
Vorteilhafterweise wirken die Granulatteilchen aufgrund der kinetischen Energie und der unregelmäßig stochastischen Struktur beim Aufprall auf die Innenwandungen schabend und zugleich auf die abgeschabte Verschmutzung bindend.advantageously, The granules act due to the kinetic energy and the irregular stochastic Structure at impact on the inner walls and at the same time binding on the scraped off dirt.
Darüber hinaus agglomerieren die Granulatteilchen nach dem Aufprall und das Verfahren kennzeichnet sich dadurch vorteilhafterweise durch eine hohe Bindungskraft der abgetragenen Verschmutzung.Furthermore agglomerate the granules after impact and the process characterized by advantageously by a high binding force the worn pollution.
Es besteht die Möglichkeit, dass der Düsenkopf mittels separatem Antrieb rotierend betrieben wird. Vorteilhafterweise könnte man dann den Düsenkopf mit einer gleichbleibenden oder aber auch variablen Drehzahl betreiben.It it is possible, that the nozzle head operated by a separate drive rotating. advantageously, could then the nozzle head operate with a constant or variable speed.
Denkbar wäre auch, dass die Rotation des Düsenkopfes durch tangentiale Rückstoßeffekte des herausgeschossenen Strahlmittels verursacht wird. Dadurch könnte das Verfahren vorteilhafterweise energieeffizienter durchgeführt werden.Conceivable would be too that the rotation of the nozzle head through tangential recoil effects of the shot-off blasting medium. This could do that Method advantageously be carried out more energy efficient.
Eine Staubbelastung bei der Anwendung des Verfahrens kann vorteilhafterweise dadurch ausgeschlossen werden, dass die Reinigung bei laufendem Lüftermotor des Abluftsystems des Kanalsystems stattfindet.A Dust exposure in the application of the method can advantageously be excluded that the cleaning while running fan motor the exhaust system of the duct system takes place.
Vorteilhafterweise sammelt sich das benutzte Strahlmittel vor einem Sieb, wobei die Siebgröße kleiner ist als die verwendete minimale Korngröße des Granulats.advantageously, accumulates the used abrasive in front of a sieve, the Screen size smaller is the minimum granule size used.
Vorzugsweise wird das Sieb in Aufwärtsumlenkungen des Kanalsystems angeordnet.Preferably the sieve is in upward deflections the channel system arranged.
Darüber hinaus sind vor dem Sieb Öffnungen im Kanalsystem vorgesehen, so dass sich das gesammelte Strahlmittel vorteilhafterweise abführen lässt.Furthermore are in front of the sieve openings in Channel system provided so that the collected blasting agent can advantageously dissipate.
An den Öffnungen, an denen sich das Strahlmittel sammelt, ist vorteilhafterweise ein Sammelbehälter für die Entsorgung des Strahlmittels vorgesehen.At the openings, where the blasting agent collects, is advantageously a Clippings for the Disposal of the blasting agent provided.
Vorteilhafte Ausführungsformen ergeben sich aus den Unteransprüchen.advantageous embodiments emerge from the dependent claims.
Die vorliegende Erfindung wird nachfolgend anhand eines in einer Zeichnung dargestellten Ausführungsbeispiels näher beschrieben.
