锌电解车间通风方案分析

Analysis of Ventilation Scheme for Zinc Cell House

锌电解车间生产过程中有大量酸雾、水蒸气产生,车间环境恶劣。本文介绍了目前锌电解车间采用的自然通风、机械通风-屋顶冷却塔排风技术的局限性,基于酸雾的运动特性,以实例着重对比了机械通风-涡旋通风、机械通风-下排风通风新技术的原理、优缺点,并根据实际情况给出通风方案选择的建议,提出改善车间环境的新思路。

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.
