Device for separating dirt and water from the extinguishing plumes in coke extinguishing towers.

The innovation concerns a device for separating dirt and water from the extinguishing steam in Kokslö.chtüraien, which essentially made of slats arranged obliquely in toothed strips to form shutter boxes Sheet metal, wood or plastic such as 2..B. Polypropylene, as well as a water jet system for rinsing off dust deposits consists of the slats.

Such devices are known, for example, from DT PS Z 100 848, DGbmS 6 913 445 and 7 145 106, in which the lamellas have dust catching noses or dripping noses at their upper ends.

In all of these devices, the water spraying systems are arranged below the lamellar trimmings and the lamellas are sprayed from below at right and oblique angles from spray nozzles and the coke and ash dust attached to them is rinsed off and it falls with dripping water onto the water pipes of the spraying devices, among other things becomes stuck there and partly clogs the spray nozzles, which therefore have to be cleaned more often. In places where coke and ash dust has settled, the material of the lines is subject to strong corrosive influences. These unfavorable influences are exacerbated by the abrasive effect of the dusty extinguishing vapors, for which the water pipes are accessible without any major obstacles.

The innovation is now based on the task of the water sprinkler system to be arranged in such a way in the extinguishing tower that dripping water and rinsed dust no longer arise the lines can reach and settle there and that they absorb the dust-laden, abrasive extinguishing vapors are not directly exposed.

To solve this problem it is proposed that the water spray system To be arranged above the slats for cleaning the extinguishing plumes of coke and ash dust.

It has surprisingly been found that when arranged the water spray system above the lamellas and a corresponding oblique-angled arrangement of the spray nozzles the lamellas succeed in removing dust from the lamellas on their underside with the jets of water to flush. The rinsed and wetted dust now falls freely down with the water droplets into the extinguishing chimney and no longer settles on the water pipes. The water pipes are also located above the slats also somewhat protected from the extinguishing vapors and they already have their abrasive dust on the underside of the fins when they reach the pipes.

When executing the extinguishing turn fixtures according to the DTPS 2 100 848, the lamellas are inserted at an angle and, thanks to the corresponding oblique-angled arrangement of the spray nozzles, the Water pipes in relation to the slats manage to get the water jets into the area under the dust catchers to steer. In doing so, they apparently get into the corner of the lamella and dust catcher nose, because it has turned out that that, according to the invention, these angles, like the other parts of the dust catchers and the lamellas, of approaches let it rinse completely.

The arrangement of the water spray device according to the invention with a device according to DTPS 2 100 848 is also particularly simple. Here are the sections of the lines to the dust

Fang shutter boxes mounted above the slats and the lines are connected to one another when the boxes are installed in the chimney of the extinguishing tower. The single ones Line sections are connected by flexible pipes and also the connection to the water supply line is made by a flexible pipe.

The invention is illustrated by the schematic FIGS and Fig. 2, for example.

Fig. 1 is a cross section and

FIG. 2 is a section along the line A-A of FIG. 1

In the figures, 1 is the outer wall of the extinguishing tower, Z is the substructure and 3 is the holder for the boxes with the lamellae 5. The flushing pipes 6 are provided with the spraying devices 8 (simple openings or nozzles) directed at the lamellas 8, and the flushing pipes 6 are held in place by the pipe supports 7 and the fastenings 7a.
