Abstract
Description
Die Erfindung bezieht sich auf eine Sprühnebelanlage zum Niederschlagen von Staub, insbesondere bei Abbrucharbeiten.The invention relates to a spray mist system for Precipitation of dust, especially during demolition work.
Bei Abbrucharbeiten mit der Zerkleinerung von Bauschutt entsteht bekanntlich viel Staub, der an jeweiligen Aufgabestellen sowie Übergabe- und Abwurfstellen immer wieder aufgewirbelt wird. Bisher hat man versucht, die Staubentwicklung mit Wasserstrahlen zu bekämpfen. Bei 4 bar Wasserleitungsdruck werden enorme Trinkwassermengen verbraucht.For demolition work with the crushing of rubble As is well known, a lot of dust is generated on the respective Drop-off points as well as handover and drop-off points again and again is whirled up. So far one has tried the Combat dust formation with water jets. At 4 bar Water pipe pressure will be enormous amounts of drinking water consumed.
Aus der JP08-246688 ist eine Abbruchmaschine mit Staubhemmfunktion bekannt, bei der eine Schaumbildungseinrichtung auf einem Fahrzeug untergebracht ist und eine Förderleitung den Schaum zu einer Düse führt, die in dem Brechwerkzeug der Abbruchvorrichtung untergebracht ist. Der entstehende Schaum soll den sich bei den Abbrucharbeiten entwickelnden Staub unmittelbar an der Entstehungsstelle umhüllen und damit binden. Die Raumausfüllung von sich entwickelndem Schaum ist nicht groß und die Erzeugung von Schaum mit nicht unbeträchtlichen Kosten verbunden.From JP08-246688 is a demolition machine Anti-dust function known in the one Foaming device housed on a vehicle and a delivery line leads the foam to a nozzle, which are housed in the breaking tool of the demolition device is. The foam that is created should be in the Demolition dust developing directly on the Cover the point of origin and bind with it. The Space filling of developing foam is not great and the generation of foam with not insignificant Associated costs.
Bei der Förderung von gebrochenem Gut über Förderbänder und Rutschen entsteht Staub, und es ist bekannt (DE 39.09 008 A1), eine Nebeldüseneinrichtung anzuwenden, in welcher eine Mehrmediendüse innerhalb einer Nebeldüsenkuppel an einem Adapterkopf angebracht ist, der sie mit den Medienzuleitungen verbindet. Diese Nebeldüsenkuppel soll die Düse gegen störende Luftströmungen abschirmen. Die Nebeldüsenkuppel stellt zwar einen gewissen Schutz gegen Materialsplitter dar, welche gegen die Austrittsdüse schlagen könnten, jedoch könnte eine solche Kuppel die Düse nicht gegen grobe Materialbrocken und Armierungseisen schützen, wie sie bei Abbrucharbeiten auftreten.When conveying broken goods via conveyor belts and slipping creates dust and it is known (DE 39.09 008 A1) to use a mist nozzle device in which is a multi-media nozzle inside a mist nozzle dome is attached to an adapter head that it with the Media supply lines connects. This mist nozzle dome is said to Shield the nozzle against disturbing air currents. The Fog nozzle dome provides some protection against Material splinters that hit the outlet nozzle could, however, such a dome could not protect against coarse chunks of material and reinforcing iron, such as they occur during demolition work.
Der Aufbau von Mehrmediendüsen, beispielsweise zur Zerstäubung von Schmierstoffen und Trennmitteln ist an sich bekannt (US-A-4 076 173). The construction of multi-media nozzles, for example Atomization of lubricants and release agents is in itself known (US-A-4 076 173).
Der Erfindung liegt die Aufgabe zugrunde, eine Sprühnebelanlage zu schaffen, die sich zur Staubbekämpfung bei Abbrucharbeiten eignet und mit geringem Wasserbedarf auskommt.The invention has for its object a Spray mist system to create dust control suitable for demolition work and with low water consumption gets along.
Die gestellte Aufgabe wird aufgrund der Merkmale des
Anspruchs 1 gelöst und durch die weiteren Merkmale der
Unteransprüche ausgestaltet und weiterentwickelt.The task is based on the characteristics of the
Der Lösungsweg bei der Erfindung geht davon aus, daß der Staub an seiner Entstehungsstelle direkt bekämpft wird, wenn die Staubwolken noch ein geringes Volumen einnehmen. Dies bedeutet aber, daß man die Sprühdüsen gegebenenfalls in der Nähe von Brechwerkzeugen anordnen muß, ohne daß die Sprühdüsen durch herumfliegende Splitter beschädigt werden dürfen. Die Sprühdüsen werden in solchen Fällen einerseits gepanzert, und andererseits ist ihr Sprühstrahl ausreichend lang und groß, um die Sprühdüse ausreichend weit von der größten Gefahrenstelle weggerückt anzuordnen.The approach in the invention assumes that the Dust is combated directly at its point of origin, if the dust clouds still occupy a small volume. This means, however, that the spray nozzles may be in the Arrange near crushing tools without the Spray nozzles can be damaged by flying fragments allowed to. In such cases, the spray nozzles are on the one hand armored, and on the other hand, their spray is sufficient long and large to make the spray nozzle sufficiently far from the to arrange the largest danger point away.
Abbrucharbeiten werden mit Abbruchmaschinen ausgeführt, so daß die Staubentstehungsstellen sich in oder nahe dieser Abbruchmaschine befinden. Die Sprühnebeldüsen werden deshalb in die Abbruchmaschine mit einbezogen, und die zu den Mischdüsen führenden Wasserleitungen und Druckluftleitungen werden von einer Versorgungseinheit beliefert, die in die Abbruchmaschine mit eingebaut ist. Die Versorgungseinheit wird in einem transportablen Gehäusegestell untergebracht, um gewissermaßen als Einschub in einen passenden Raum der Abbruchmaschine integriert zu werden.Demolition work is carried out with demolition machines, so that the dust formation points are in or near this Demolition machine. The spray nozzles are therefore included in the demolition machine, and that to the Mixing nozzles leading water pipes and compressed air pipes are supplied by a supply unit, which in the Demolition machine is installed. The supply unit is housed in a portable housing rack to a certain extent as a slide into a suitable room in the Demolition machine to be integrated.
Bei der Sprühnebelerzeugung entsteht eine Temperaturabsenkung, die zur Eisbildung führen kann. Um dies zu verhindern, ist eine Heizeinrichtung vorgesehen, wobei zweckmäßigerweise die Abluft des Kompressors der Versorgungseinheit zu Heizzwecken verwendet werden kann.One is created when the spray is generated Lowering of temperature, which can lead to ice formation. To do this To prevent a heater is provided, wherein expediently the exhaust air of the compressor Supply unit can be used for heating purposes.
Die Wasserzufuhreinrichtung ist mit Ventilen bestückt, um einerseits die Regelung der Wasserzufuhr zu gewährleisten und andererseits die Wasserleitungen bei Nichtgebrauch der Anlage von Wasser zu befreien, um der Gefahr des Einfrierens zu begegnen. Aus gleichem Grund kann das Wasser eines Wassertanks abgelassen werden.The water supply device is equipped with valves, on the one hand to ensure the regulation of the water supply and on the other hand the water pipes when the Remove water from the system to reduce the risk of freezing to meet. For the same reason, water can Water tanks are drained.

Der Sprühnebel wird generell in der Nähe der Entstehungsstellen des Staubes erzeugt, und diese Staubentstehungsbereiche werden von dem Sprühnebel gänzlich eingehüllt. Deshalb wird sich entwickelnder Staub sofort gebunden und kann sich nicht als Staubwolke ausbreiten. Auf diese Weise kann trotz geringen Wasserverbrauchs die Staubentwicklung wirksam bekämpft werden.The spray is generally near the Generations of dust, and this Areas of dust formation become entirely from the spray shrouded. That is why developing dust immediately bound and cannot spread as a cloud of dust. On this way, despite low water consumption Dust development can be combated effectively.
