Description

一种酸雾处理装置An acid mist treatment device

技术领域technical field

本实用新型属于带钢酸洗净化的技术领域,尤其涉及一种酸雾处理装置。The utility model belongs to the technical field of strip steel pickling and purification, in particular to an acid mist treatment device.

背景技术Background technique

经冷轧后的带钢表面带有大量的残留物,主要为轧制油、铁粉以及松散杂质等,这些残留物的存在对后续工序带来不利影响,并导致最终成品质量恶化,硅钢和镀锌板等生产过程中对冷轧后的带钢表面必须进行清洗。清洗工艺一般是包括碱喷洗、碱刷洗、电解清洗、水刷洗、水喷洗等的组合式多级强化清洗。After cold rolling, there are a lot of residues on the surface of the strip steel, mainly rolling oil, iron powder and loose impurities. In the production process of galvanized sheet, etc., the surface of the strip steel after cold rolling must be cleaned. The cleaning process is generally a combined multi-stage intensive cleaning including alkaline spray cleaning, alkaline scrubbing, electrolytic cleaning, water scrubbing, and water spray cleaning.

冷轧带钢轧制后经过目前常用的多级强化清洗能有效去表面残留的轧制油、铁粉以及松散杂质等,表面清洁度高,获得良好的清洗效果。清洗液一般为一定浓度的碱液,生产过程中,当碱液的浓度降低或者活性降低时,会排出一部分碱液,排除的碱液送到废水处理站中和处理后在进行排放。这样一方面废碱液还有一定浓度的碱性成分,另一方面废水处理也使得生产成本提高。而冷轧生产过程中,热轧带钢大多先要进行酸洗再进行轧制,酸洗过程中产生大量酸雾需要净化,因此,提供一种利用带钢清洗过程排放的废碱作为酸洗吸收介质净化酸雾的装置,具有实质意义。After the cold-rolled strip is rolled, the commonly used multi-stage intensive cleaning can effectively remove the residual rolling oil, iron powder and loose impurities on the surface. The surface cleanliness is high and a good cleaning effect is obtained. The cleaning solution is generally a certain concentration of lye. During the production process, when the concentration or activity of the lye decreases, a part of the lye will be discharged, and the removed lye will be sent to the waste water treatment station for treatment and then discharged. In this way, on the one hand, the waste lye also has a certain concentration of alkaline components, and on the other hand, the waste water treatment also makes the production cost increase. In the cold-rolling production process, most of the hot-rolled strips are first pickled and then rolled, and a large amount of acid mist is generated in the pickling process and needs to be purified. The device for purifying acid mist by absorbing medium has substantial significance.
