摘要
酸雾的排放会形成酸雨,因此对于酸雾的减排控制和烟气的脱酸工程受到关注。本论文是以酸洗槽所产生的废气为例,设计处理其废气的净化系统,从而使净化后的气体达到排放标准。在进行设计过程中,其重点为填料塔的设计。填料床反应器一般为逆流操作,具有操作适应性好、结构简单、能耐腐蚀等优点,广泛地用于带有化学反应的气体的净化过程,适合液膜控制的吸收过程,如水吸收***气、碱吸收硫酸和水吸收氧气等。对设备的选取也进行经济分析,经过选取后,该设计的总成本大约为34000元。

Abstract
Because the discharge of the acid fog can turn into acid rain .we focus on controlling reducing the discharge of the acid fog and flue gas emission reduction projects deacidification . The paper is based on exhaust gas generated by pickling tank for example. Designed to handle its exhaust gas purification system, so that the gas is purified to meet emission standards. During the design process, the point is design of packed tower. Packed bed reactor always uses counter-current operation, with good operating flexibility, simple structure, resistant to corrosion, etc., are widely used in purification system of gas with chemical reaction , which suits for absorbent process of the controlling in liquid film, such an water absorption of chlorine and alkali sulfuric acid and water absorption to absorb oxygen. it introduces device materials and we are economic analysis of device. After selecting, the design of total cost is about 34000 yuan.
Key words: waste gas purification, acid mist, packed tower, project, picking bath

前言
在现代的工业生、生活中,酸雾主要来源于化工、机械制造、冶金等用酸过程中,像是制酸、酸洗、电镀中。酸雾的排放会导致酸雨[1]。酸雨又对人们和建筑有危害。若对于排放的酸雾不加以处理净化,
