The second layer of rod-shaped elements is positioned at a distance from one another along the plane transverse to the direction of gas flow. The of rod-shaped elements extend across the gas flow channel. The second layer is structured to move relative to the first layer to define at least one of: (i) one or more additional operating positions; and (ii) an out-of-phase position.

DETAILED DESCRIPTION OF THE INVENTION

[0030] FIG. 1 schematically shows a gas flow channel 1 of a flue gas scrubber system. An installation 10 is located in the gas flow channel 1, wherein said installation 10 is a coalescer that comprises of a first (upper) layer 2 of rod-shaped elements disposed parallel to one another, and a second (lower) layer 3 of rod-shaped elements disposed parallel to one another. In this context, the rod-shaped elements of the first layer 2 and the second layer 3 are disposed offset to one another, so that they overlap in the gas flow direction (from below to above), and a curved flow path is formed between them.

[0031] In this embodiment, the second lower layer 3 of the coalescer is movably disposed. As indicated by the arrows, it can be moved downward from the position indicated by solid lines to a position 4, which is indicated in dotted lines. When the second layer is located in the lower position 4, the two layers 2, 3 have a larger distance from one another that corresponds to an out-of-operation position. Therefore, if the coalescer is to be taken out of operation, the lower layer 3 is moved downward to position 4 by a movement apparatus not shown here.

[0032] In the embodiment of FIG. 2, an installation is equally provided that is formed as a coalescer and has a first upper layer 2 as well as a second lower layer 3. Both layers are aggregated from rod-shaped elements disposed next to one another at a distance, in this case tubes. In this context, to bring the second layer 3 into an out-of-operation position, the layer is moved laterally out of the gas flow channel 1, as represented by the dotted lines in 5.

[0033] In the embodiment shown in FIGS. 3 and 4, the rod-shaped elements of the second lower layer 3 are moved vertical to the axis of the flow channel 1 in the drawing plane from left to right, so that the overlap of the rod-shaped elements of the two layers 2, 3 becomes zero. When the rod-shaped elements of the two layers align, the installation is placed out-of-operation since flow deflection can no longer occur.

[0034] FIGS. 5 to 7 show the first embodiment shown in FIG. 1 in more precise depictions. FIG. 5 shows four hydraulic cylinders 6 that are arranged under the second layer 3 and move it parallel to the axis of the flow channel. FIG. 6 shows the mounting of the installation on support holders 7, on which the hydraulic cylinders 6 are disposed, which support the second lower layer 3 of the installation. Furthermore, a nozzle tube 8 is shown, which serves to continuously spray the installation via hoses. Additional hoses lead from the nozzle tube 8 to the hydraulic cylinders 6.

[0035] FIG. 7 shows a hydraulic cylinder 6 in detail with a plunger rod 9 and a plunger 12, as well as a water intake 11.

[0036] This embodiment is formed so that upon switching on the flushing (via the nozzle 8), the lower layer 3 is raised above the hydraulic cylinder 6 once the pressure is present in the hydraulic cylinders. This is typically 2 bar. In this state, the tube coalescer shown here has a small limit droplet and the associated pressure loss. Once the flushing is stopped, the lower layer 3 moves back to its starting position. The tube coalescer then has low pressure loss and a large limit droplet. The moving back to the starting position ideally takes place via the own weight of the lower layer 3. If this is not sufficient, it can naturally also be realized via a second water connection in the hydraulic cylinder 6. Then however a second inlet to the hydraulic cylinders would have to be laid from the outside.
