Assembly for wet cleaning of combustion gases derived from combustion processes, especially the combustion of coal, coke and fuel oil

An assembly for wet cleaning of combustion gases derived from combustion processes, said assembly being disposed between a furnace installation and a chimney, comprising:

• at least one dust extracting device having a dust extracting fluid contained therein, said dust extracting device having an outlet, and
• at least one dust absorbing device connected to the outlet of the dust extracting device, wherein the dust absorbing device includes a vessel having an absorbing fluid contained therein,
• wherein combustion gases are introduced into said dust extracting fluid and are discharged therefrom through a filtering means disposed in said dust extracting fluid, wherein the dust extracting device includes a main vessel having a bottom which forms a ridge roof structure, a first auxiliary vessel and a second auxiliary vessel situated such that in a view from above, the main vessel and the first and second auxiliary vessels form a shape approximating a letter Z, wherein a middle part of the letter Z is made up of the main vessel, and the arms of the letter Z are made up of the first and second auxiliary vessels,
• wherein the main vessel is equipped with a first helical conveyor and a second helical conveyor provided in first and second low portions, respectively, of the ridge roof structure, said first and second conveyors provided for discharging sediments to first and second sediment tanks provided in the first and second auxiliary vessels, respectively,
• first and second devices for discharging waste fluid disposed in the first and second sediment tanks, respectively,
• wherein at an outlet for introducing a stream of combustion gases into the dust extracting fluid, a guide is provided which substantially encloses the stream of combustion gases, and wherein the filtering means is disposed above the guide, and
• wherein the vessel of said dust absorbing device includes a coaxially disposed duct for outputting cleaned flue gases, and a filtering means is provided in the dust absorbing device extending toward a bottom of the dust absorbing device with respect to the duct.
