During the production process of a zinc cell house, a large amount of acid mist and water vapor are generated, and the environment in the plant building is harsh. This article introduced limitations of the natural ventilation technology and mechanical ventilation-top cooling tower exhaust ventilation technology currently used in zinc cell houses.Based on the motion characteristics of acid mist，the principles, advantages and disadvantages of the various ventilation schemes such as mechanical ventilation-vortex ventilation, mechanical ventilation-down exhaust ventilation were emphatically compared with examples. According to the actual situation, suggestions for the selection of ventilation schemes were given, and new ideas for improving the workshop environment were put forward.
