Description

The invention relates to a mobile device with a Vehicle with a spray and suction device for cleaning and / or de-coating of surfaces, especially roadways, Landing strips of airfields, parking lots etc., where rubber abrasion, Oil residues, heavy metals or similar pollutants by means of applied to the surface under high pressure Detached water, this water with the impurities sucked up, passed through a separator and in a cycle Storage tank for the cleaning water fed back becomes.

Such a mobile device is from DE-OS 31 33 789 known. The sprayed and sucked up water is cleaned by means of filters and separators to be able to reuse it.

From DE-OS 28 34 996 and the advertising document "Das Atümat- System "from Woma Apparatebau, Duisburg are mobile Devices with a vehicle with a spray and suction device for cleaning sewers and their processes known, the impurities by means of applied to the channel surfaces under high pressure Detached water and this water with the Impurities sucked up by several in a row  switched separator directed and in the circuit one Storage tank for the cleaning water fed back becomes.

Furthermore, from DE-OS 28 48 961 is a mobile Device for cleaning, emptying and disposing of Collection pits known, in which the from the collection pit extracted thin sludge via an addition device Flocculants are added, creating an immediate Flocculation in the thin sludge tank during its Filling should take place. This is then filtered out with retention of the flocculated sludge components, while the filtrate in a water collector is collected. This more or less cleaned Filtrate is later returned to the cleaned pit returned.

Roadways and especially runways from Airfields have contaminants that affect the previously known and in the previous publications described way not removed from the dirty water can be. These are through the previous separation technology on mobile devices of the type mentioned in the beginning cannot be separated Impurities especially around heavy metals and their salts or also mineral oils or the like desired and also known multiple use of the cleaning water again and again to the one to be cleaned Area and ultimately not removed, but can even get into the groundwater.

A remedy would be with the previously known devices only possible that the absorbed dirty water  not with these from the separators previously used detectable contaminants used only once and then cleaned in a complex wastewater treatment plant becomes. This would of course result in a very uneconomical one Mode of operation because of the capacity of cleaning water is limited in a cleaning vehicle, so that the stock would be used up very quickly if he should only be used once. It is therefore known to be sought that such a cleaning vehicle can drive and clean as long as possible to the largest possible area in the shortest possible time to cope with the cleaning water several times should be usable.

There is therefore the task of a device to create the type mentioned, in which the advantage the reusability of a large part of the cleaning water remains directly in the device, nevertheless not detectable by the previous separators Pollutants such as heavy metals and the like also be eliminated and their re-discharge to the cleaning surface is avoided, the device can also be in operation during the separation process and not for the deposition of such Pollutants from the cleaning water stopped must be in order to stir up such pollutants again to avoid.

The mobile device is used to solve this problem of the generic type, characterized in that at least the first of the series Separator as a pre-separator for separating the coarser components is formed and that at least one of the separators is a liquid container, the one flotation mixer for feeding and fine bubbles  Distribution of air or the like gas into the contaminated water has and on which to introduce flocculation and / or flocculation aids dosing pumps or the like are.

This way you can not mechanically Filters or filter presses separable mineral oils, heavy metals and fine suspended particles and colloidal Impurities as well as dissolved substances from the Water to be removed. The flocculants form namely with these impurities relatively large flakes which bubbles of the blown air or the injected gas can accumulate, so that these flakes float up to the surface, using the Dosing pumps always appropriate flocculation or Flocculants are added to the process to continue continuously.

So there is a foam carpet in which the Dirt flakes are embedded that way can be skimmed off very easily. Such Separation can also take place while driving and out of it resulting movements of the vehicle in contrast for example for cleaning according to the principle of Sedimentation are carried out in settling tanks usually carried out using a precipitant becomes.

Tests have shown that with the aforementioned Device in which initially the coarser components excreted and then by flocculant and air or gas, even those that are difficult to remove Components are separated, the dirty water clear again and without difficulty for another Cleaning becomes reusable without the special  dangerous pollutants in this reuse get back to the surface to be cleaned.

Embodiments of the invention and in particular the Liquid containers are the subject of claims 2 to 8.  

Especially when combining the above and in the Features and measures contained claims mentioned results in a mobile device, which with relative high speed over also very dirty and Drive areas covered with pollutants and clean them can, the cleaning water is reusable, without dissolved or colloidal pollutants be carried out and without the water for the separation of such pollutants in a Sewage treatment plant would have to be brought. So the benefits the cleaning of such areas with high pressure water be, actually, as far as possible Removal of all possible pollutants can be accomplished can and these pollutants in a concentrated form on the Vehicle itself can be collected for destruction.

The following is an embodiment of the invention based on the drawing described in more detail.

The only figure shows a schematic representation a device designed as a cleaning vehicle with a spray and suction device as well as separators in which the cleaning water prepared for reuse after use becomes.

A mobile device designated as a whole with 1 is equipped as a vehicle with a spray and suction device 2 in order to be able to clean and / or de-coat roadways, landing strips, parking lots, large halls and such areas, whereby rubber abrasion, oil residues and the like this surface to be cleaned is removed from a reservoir 3 under high pressure, this water is sucked up with the impurities, freed from the impurities and pollutants taken up in a manner to be described and is returned to the reservoir 3 for the cleaning water in the circuit.

Here, several separators to be described in detail for separating solids and / or dissolved and undissolved pollutants from the dirty water are connected in series in several stages on the vehicle, at least one of these separators - in the exemplary embodiment two such separators - being liquid containers 4 and 5 , into which flocculants and air can be fed to carry out flotation.

In the drawing it can be seen that the liquid container 4 and also the liquid container 5 each have a flotation mixer 6 for the introduction and fine-bubble distribution of air into the contaminated water. For the introduction of flocculation or flocculation aids 4 dosing pumps 7 are connected to the liquid container, the lines 8 of which are shown schematically.

At least a revolving paddle 9 or a similar scraper can be provided at the liquid surface of the liquid container 4 and the liquid container 4 has an outlet opening 10 to a collecting vessel 11 for the discharged foam with pollutants.

In the exemplary embodiment, the further liquid container 5 is connected directly downstream of the first liquid container 4 , a transition being provided in the lower region of the partition 12 between these liquid containers 4 and 5 .

The last liquid container 5 in series is connected via a connecting line 13 with a pump 14 to the reservoir 3 for the cleaning water, so that the cleaned water is supplied to this reservoir 3 again and again. A connection via a line with a natural gradient would also be possible.

In the drawing it can also be seen that a suction hose 15, which starts from the spraying and suction device 2 , first opens into a pre-separator 16 , in which the flow cross section of the incoming jet is greatly enlarged, so that the solids are due to the air-liquid mixture sudden drop in speed. A liquid line 17 leads from the pre-separator 16 to a filter or sieve 18, which in the exemplary embodiment is designed as a rotating slotted sieve, from which a connection for the water to a collecting container 19 is provided.

This collecting container 19 thus contains an already pre-cleaned water and is connected to the liquid container 4 via a line 20 by means of a pump 21 , so that a largely pre-cleaned water is subsequently treated in the liquid containers 4 and 5 , so that several separators of different types are connected by this series connection Finally, a clear water flows back into the reservoir 3 .

It should also be mentioned that the dirt flakes stripped off on the surface of the liquid container 4 can be passed into filter bags, where the residual water can also drip off. If this happens in the collecting container 11 , this residual water can be fed back into the entire water cycle and the cleaning water can thus be used even better.

Experiments have shown that the device 1 with a sufficiently large storage container 3 can work continuously for several hours, so that even large areas can be cleaned quickly, which is absolutely necessary, for example, on the runways of airfields or public roads, since these can only be blocked for a very short time. Nevertheless, there is a much more thorough removal of pollutants compared to previous cleanings, so that this cleaning of the roadway does not result in a considerable proportion of the pollutants located in the sewage system or the surrounding vegetation. Rather, these pollutants are also absorbed and excreted with great safety and in a very high percentage while driving, where they are already concentrated in the device 1 so that subsequent disposal can take place in the usual way.
