Background

In the production process of hot galvanizing, a zinc pot can generate zinc fume waste gas pollutants which are mainly zinc oxide dust, the zinc oxide can generate toxic gas due to high thermal decomposition, and the zinc fume generated by galvanizing needs to be purified in order to avoid the dust polluting the environment. The traditional zinc fume evolution treatment mode is a method of introducing zinc fume into a spray purification tower for spraying and then discharging the zinc fume into the atmosphere. However, the method has the problems of single purification and incomplete purification, and the zinc fume discharged to the atmosphere still contains substances polluting the environment and cannot meet the secondary standard of the comprehensive emission standard of atmospheric pollutants specified by the state. In addition, the traditional purification spray tower only can play a simple role in purifying flue gas, and zinc oxide settled to the bottom of the tower body can be directly discharged from a water outlet along with spray water, so that the zinc oxide can not be recovered for the subsequent extraction of metal zinc, and the waste of the zinc oxide is caused.
