    description
    Subject matter and / or technical field The invention relates to a mobile device and a method for dewatering sludges, consisting of a container having a water inlet and outlet device and a filter device inserted into the container, for example a removable filter bag. The drainage is carried out according to the method that the sludge to be dewatered are fed around a pipe system, they are soothed on baffles evenly within the hinged filter bag to sediment by gravity. During sedimentation, the PH value is neutralized by supplying CO2 gas. The purified water drains off via a second pipeline. After the sedimentation has occurred or when the tinsel capacity of the filter bag is exhausted, it can be replaced by a lifting device through an empty filter bag. The cycle starts again.
    We are seeking patents which contains the technical facts of corresponding processes and products that have as many of the above features. The aim of the research is to make an FTO assessment based on the results.
    Presentation of the invention
    PRIOR ART Similar solutions are already known from DE 3 231 186, which describes a device for dewatering sludges.
    Disadvantages The addition of the flocculant requires additional metering units for which separate housings are required. In constantly changing location of use of the container, each of the associated flocculant must be transported separately to the new site and always connected again to the container, or adjusted accordingly. The conventional systems are extremely cumbersome, especially in changing locations and also costly in the production due to its own frame and housing. As exemplarily shown in DE 3 231 186, some existing systems have a filter device, which are designed mechanically rigid by perforated plates and which must be removed from the vessel with full filter, cleaned and reused, alternatively mounted in the vessel, the filter materials must be extracted , An almost interruption-free operation is not possible with such systems. The replacement of the filter unit also carries risks and has caused accidents in the past.
    OBJECT The object of the invention is to provide an apparatus and a method by which the dehydration of liquid sludges, or contaminated liquids, by the addition of gaseous CO2 PH neutral is possible and the filter element is designed to be interchangeable. In addition, costly suction can be avoided. At the same time, the invention offers the advantage of accident prevention for the user, this through the PH neutralization and the mechanical structure with the flexible filter element. Solution The problem is solved by the features of the independent patent claims. The fact that the filter insert is designed to be flexibly interchangeable, which allows an almost interruption-free operation when replacing the filter insert. This, in which the filter cartridge can be easily and quickly replaced by a low cost collapsible new filter. Alternatively, the filter cartridge can be aspirated or dumped as described in the prior art. The filter materials remain in the case of an exchange in the filter cartridge and can be supplied with this disposal. The filter performance of the filter device is designed such that it does not require the addition of precipitants. The PH neutralization is carried out by blowing in gaseous CO2, which can be easily installed at the respective place of use and put into operation with the mobile device according to the invention.
    Advantages The advantage of the invention is that a trouble-free emptying of the dewatered sludge is made possible. The regulations under water protection SIA 431 are complied with and extraction processes due to external influences are eliminated. The safety regulations are complied with.
    Aufzählung der Figuren / Zeichnungen The invention will be explained in more detail with reference to an embodiment which is illustrated in the drawings.
