2, spray column of the present invention due to flue gas even distribution and preliminary arrangements be inverted cone-shaped, inlet flue gas rotates rising wherein, flue dust obtain part remove, flue dust clearance can reach 90%.
Accompanying drawing explanation
Fig. 1 is each modular construction layout drawing of the present invention;
Fig. 2 is the flue gas even distribution of Fig. 1 and the structure enlarged diagram of rough dusting device.
Detailed description of the invention
For content of the present invention, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows.It should be noted that, the present embodiment is descriptive, is not determinate, can not limit protection scope of the present invention thus.
A kind of spray column of new type purification flue gas, as depicted in figs. 1 and 2, in the present embodiment, spray column is circular, described spray column comprises smoke inlet 10, exhanst gas outlet 1, demister 2, spray equipment 3, slurry pool 6 and oxidation unit 9, the bottom of described spray column arranges smoke inlet, the upper top of spray column arranges exhanst gas outlet, spray equipment and demister is set gradually, successively to being arranged with slurry pool and oxidation unit in the spray column below smoke inlet in spray column between smoke inlet and exhanst gas outlet.The lower end that this exhanst gas outlet is connected with tower wall is higher than demister upper end 3000mm.In the present embodiment, this spray equipment is connected with slurry pool with spray pump 7 by pipeline, and in the present embodiment, spray equipment is 3 grades of spray equipments, and in the present embodiment, oxidation unit is connected with oxidation fan 8 by pipeline.
