- the invention relates to a cleaning vehicle for tunnels with a travel drive, a washing liquid container, and a cleaning unit with cleaning brushes and cleaning nozzles connected to the washing liquid container via leads for dispensing the washing liquid against the tunnel inner wall, according to the preamble of claim 1.
- Tunnel inner walls become increasingly dirty as the tunnel is used and must be cleaned at regular intervals.
- cleaning vehicles which are provided with cleaning brushes and cleaning nozzles, the cleaning nozzles using high-pressure pumps spray a washing liquid under high pressure against the tunnel inner wall and clean the cleaning brushes the tunnel inner wall.
- high-pressure pumps spray a washing liquid under high pressure against the tunnel inner wall and clean the cleaning brushes the tunnel inner wall.
- washing liquid causes in practice but sometimes difficulties.
- washing liquid via injectors to mix a compressed air flow generated by their own blowing nozzles, and spray the aerosol thus formed under pressure against the tunnel inner wall, whereby the
- Wax liquid are allowed.
- Claim 1 relates to a cleaning vehicle for tunnels with a drive, a washing liquid container, and connected to the washing liquid container via leads cleaning unit with cleaning brushes and
- Pre-cleaning of the polluted washing liquid is connected, and the sedimentation is connected via a supply line for the prepurified washing liquid with a prepurifying unit for the prepurified washing liquid, a flocculation stage and a flocculation stage downstream
- Sedimentation stage includes, and a return line for the purified washing liquid is provided by the treatment unit in the washing liquid container.
- the cleaning vehicle according to the invention thus not only sees the collection and preparation of the polluted
- Preparation must be made in a quality sufficient for reuse with high pressure pumps and nozzles.
- Sedimentation tanks settle solids that are heavier than water.
- the overflow water can be pumped off and represents pre-cleaned scrubbing liquid, which, however, can not yet be used for the high-pressure pumps and nozzles of the scrubbing unit, as Applicant has discovered.
- a treatment unit with a flocculation stage and a sedimentation stage downstream of the flocculation stage is provided, with which colloidal solids can be removed.
- Wash fluid container of the cleaning unit to be pumped.
- the sedimentation tank is connected to a storage tank via a first supply line for the prepurified washing liquid, and the storage tank is connected to the treatment unit via a second supply line
- the treatment unit can be operated independently of the amount of wastewater immediately accumulating in the sedimentation tank, whereby in particular, the operation of the flocculation step and the dosage of the flocculant is facilitated.
- the treatment unit be a downstream of the sedimentation filter stage
- Subordinate pressure booster pump may be provided in order to operate the filter stage optimally. With the filter stage can remain in the overflow sedimentation
- Filter level can vary, preferably about
- Bag filters are simply constructed filters that are used to
- Activated carbon filters or devices for UV sterilization can be provided.
- the treatment unit has a cuboid casing, wherein the flocculation step extends along an inner longitudinal side of the casing within a first cuboid half, and the sedimentation step extends along an inner broad side of the casing.
- the Processing unit can be placed with its cuboid wrapping about on a wagon of a rail vehicle.
- the flocculation step comprises in particular a
- the arrangement of the flocculation step along an inner longitudinal side of the casing within a first cuboid half of the casing requires a
- the length of the flocculation tank is preferably greater than its height, and the height is preferably greater than its width.
- the by the movement of the flocculation tank is preferably greater than its height, and the height is preferably greater than its width.
- Flocculant container located liquid reduced. Of the Flocculant is at its inlet with the
- the filter stage can be arranged along an inner longitudinal side of the casing within a second cuboid half, so that the cuboid
- Interior of the processing unit is used optimally.
- the treatment unit comprises means for pH neutralization of the washing liquid.
- lamellar clarifiers In the bottom area, lamellar clarifiers have several slanted plates arranged in parallel in order to maximize the sedimentation area in relation to the available space, which is very difficult under the given limited space
- the suction unit is designed as a suction hood arranged in the direction of travel after the cleaning unit.
- the suction unit connected to the sedimentation tank is thus located in the immediate spray-out area of the washing liquid and can thus detect a maximum amount of the sprayed washing liquid.
- Fig. 1 is a schematic representation of an embodiment of a cleaning vehicle according to the invention seen from above, and the
- Fig. 2 is a schematic representation of an embodiment of the treatment unit. Reference is first made to Fig. 1, which is a schematic representation of an embodiment of a
- washing liquid container 8 via cleaning lines 5 connected cleaning unit 1 with rotating cleaning brushes 3 and arranged on spray bars cleaning nozzles 4 for dispensing the washing liquid shows.
- the supply lines 5 are designed as flexible hose lines, which extend on a support for fixing the cleaning unit 1 on the cleaning vehicle.
- the washing liquid is not visible on high-pressure pumps (in Figs. 1 and 2), which are connected to the
- Supply lines 5 or the cleaning unit 1 may be sprayed under pressure against the tunnel inner wall.
- suction hood 2 As seen in the direction of travel after the cleaning unit 1 arranged suction hood 2 is part of a suction unit, which is held on a provided with hose 14 carrier, and is connected via the hose lines 14 with a sedimentation 6, in the extracted and contaminated
- the sedimentation tank 6 is connected via a first supply line 9 for the pre-cleaned scrubbing liquid with a storage tank 7, and the storage tank 7 via a second supply line 15 with the processing unit 11.
- the processing unit 11 is in turn with a return line 10 for the cleaned scrubbing liquid with the scrubbing liquid container eighth
- Embodiment is further provided a residence container 12 for the operating crew of the cleaning vehicle.
- the cleaning vehicle is further designed as a rail vehicle, in which all containers and the processing unit 11 are arranged on wagons, as shown schematically in FIG. 1.
- washing liquid which via a first supply line 9 in a storage container 7 for the subsequent
- Processing unit 11 is pumped.
- the storage tank 7 is connected via a second supply line 15 with the processing unit 11, the one
- FIG. 2 shows a schematic representation of an embodiment of a treatment unit 11.
- the flocculation stage 16 is formed by a flocculation tank 18 and a flocculation agent supply 19 with corresponding agitators 20, and serves for the purpose
- the flocculation tank 18 is connected for this purpose at its inlet to the storage tank 7, and at its outlet with the sedimentation stage 17 and can be achieved in a einlaufseifiges reactor pool 18 a, in which a predominantly good mixing of the washing liquid to be cleaned with the flocculant, and an expiring soap Consolidation basin 18b, in which mainly the formation of settleable flakes is to be achieved.
- a flocculant is preferably a
