TECHNICAL FIELD

[0001] The utility model relates to waste gas treatment technical field, concretely is a kind of waste gas treatment device for pickling of titanium anode production. BACKGROUND

[0002] A large amount of acidic waste gas is generated in pickling process, and the main components include hydrogen chloride, sulfuric acid mist and the like. These acidic gases are generated due to volatilization of acid liquid used for pickling. If these acidic waste gases are directly discharged into the atmosphere without treatment, they will cause serious harm to the environment and human health.

[0003] Most of the prior art sprays reagent inside the treatment tower to neutralize it, and the sprayed reagent can be recycled to the reagent tank for continuous use. Although this reduces costs and prevents waste, the concentration of neutralizing reagent in the spray liquid gradually decreases during continuous treatment of waste gas. When the concentration of reagent is insufficient, it cannot effectively precipitate or adsorb these heavy metal ions, which increases the impurity content in the waste gas, thereby affecting air quality and endangering human health. Therefore, we propose a waste gas treatment device for pickling of titanium anode production. SUMMARY
