3More than.
Summary of the invention
In view of this, the purpose of this utility model is to provide a kind of blast furnace gas wet cottrell for smart dedusting, can adapt to the various operating modes of blast furnace, and energy consumption is little, has also removed the Korrosionsmedium in the coal gas simultaneously.
For achieving the above object, the utility model provides following technical scheme:
A kind of blast furnace gas wet cottrell, comprise cylindrical shell, described cylindrical shell bottom is connected with the ash collection slot that catchments, be provided with support frame in the described cylindrical shell, described support frame is provided with receiving electrode and corona discharge electrode, and described corona discharge electrode is arranged in the receiving electrode, and the cross section of described receiving electrode is the limit number greater than 3 regular polygon, the distance on each limit of polygon centre distance is 150～350mm, and the cross section of corona discharge electrode is that star-like barb type and prickle quantity are equal with receiving electrode polygon limit number.
The cross section of described receiving electrode is regular hexagon.
Also be provided with receiving electrode flushing deashing device and corona discharge electrode ash removal equipment for flapping on the described support frame.
Described cylindrical shell is cylindrical shape, and the described ash collection slot that catchments is cone shape.
The beneficial effects of the utility model are: receiving electrode of the present utility model adopts regular polygon, can take full advantage of the electric cleaner inner space, expand the receiving electrode area, under the situation of identical coal gas treating capacity, barrel diameter is littler, energy consumption is little, the utility model is strong to the adaptability of blast furnace operating mode, can adapt to the various operating modes of blast furnace, and security of system is reliable.
