Central axes are provided with central axis in scrubbing section, are provided with helical blade on the central axis and scrubbing section is divided into helical duct,
Helical blade downside is evenly arranged with spiral helicine sparge pipe, and downward spout, the spout are evenly arranged on sparge pipe
For diffusion type；Sparge pipe connects water pump by pipeline.
As a kind of improvement of this programme, the spiral helicine sparge pipe axis is center axis axis, and sparge pipe is at least set
It is equipped with one, adjacent hydrojet tube spacing is not less than 7.5cm, hydrojet from 15cm, sparge pipe distance center axis minimum range is not less than
Pipe is not less than 7.5cm apart from scrubbing section inner wall minimum distance, and spout spacing is not less than 15cm on sparge pipe.
As a kind of improvement of this programme, the air inlet area lower part is tapered configuration, and leakage fluid dram is located at bottom centre position
It sets.
As a kind of improvement of this programme, the electric hot plate is set to air inlet area top, and air inlet is located at below electric hot plate.
As a kind of improvement of this programme, helical blade spiral number of turns are no less than 2 circles in the scrubbing section.
The utility model has the advantages that a kind of spray equipment for handling mercury fume of the present invention, scrubbing section is provided in tower body
Scrubbing section is divided into spiral flue by helical blade, helical blade, increases the path length that mercury fume flows in scrubbing section,
Mercury fume residence time in scrubbing section is improved, the time of contact of absorbing liquid and mercury fume that sparge pipe sprays is increased,
So that absorbing liquid is fully absorbed the mercury in mercury fume, greatly improves clean-up effect.In the shape of a spiral, more sparge pipes are arranged side by side for sparge pipe
It places, is evenly arranged with downward spout on sparge pipe, guarantee to be uniformly filled in atomization in spiral flue that helical blade is separated into
Absorbing liquid drop, guarantee mercury fume sufficiently with absorbing liquid drop contact.
Be provided with electric hot plate in air inlet area, for heating flue gas, improve smoke moisture, make flue gas in scrubbing section with suction
It receives liquid drop more fully to contact, improves the absorptivity of mercury, promote the clean-up effect of mercury fume.
The spray equipment of the processing mercury fume can connect in the cleaning equipment unit of processing mercury fume,
The water pump that sparge pipe is connected, which can connect, stores the equal chemical reagent absorbed for mercury of liquor natrii hypochloritis.For to mercurous cigarette
Mercury in gas is fully absorbed, and pollutes environment after preventing flue gas emission.
A kind of spray equipment of processing mercury fume greatly improves the absorption effect to mercury ingredient in mercury fume
Fruit improves gas cleaning rate.
