The specific embodiment
The utility model provides a kind of chloride smoke absorption, purifier, for making the purpose of this utility model, technical scheme and effect clearer, clear and definite, below the utility model is further described.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
A kind of chloride smoke absorption, purifier that the utility model provides, it comprises: absorbing medium, five spray columns, five raw material circulating slots, absorbing medium treating apparatus.Described five spray columns set gradually, and described absorbing medium is copper anode mud slip.
Specifically, described absorbing medium is for absorbing the chlorine of chloride flue gas, and described five spray columns are used for passing through chloride flue gas spray-absorption medium wherein, and five raw material circulating slots are used for storing absorbing medium.
Chloride flue gas is successively by five spray columns, and in spray column with copper anode mud slip haptoreaction, enter atmosphere after removing chlorine; Copper anode mud slip relies on gravity from spray column, to enter the raw material circulating slot corresponding with described spray column, then enters by the power set in raw material circulating slot the circulation that spray column is realized copper anode mud slip.
Refer to Fig. 1, it is the schematic diagram of chloride smoke absorption of the present utility model, purifier embodiment.As shown in the figure, described chloride smoke absorption, purifier comprise five spray columns: one-level spray column 1, secondary spray column 2, three grades of spray columns 3, level Four spray column 4 and Pyatyi spray columns 5; Each spray column below all correspondence is provided with a raw material circulating slot 6.
The trend of chloride flue gas is (for convenience of description, in figure, by chlorine trend, represent), from deselenization reactor 12, enter in one-level spray column 1, the copper anode mud slip haptoreaction under spraying with tower top, the flue gas after being absorbed, purified by five spray columns is extracted in atmosphere by titanium blower fan 13.
Under acid condition, chlorine has strong oxidizing property, can promote that the insoluble Cu oxidation dissolutions such as elemental copper in copper anode mud, cuprous sulfide are copper chloride solution.Key reaction is as follows:
Cu?+Cl
2?=?CuCl
