一种酸再生文丘里后负压降低的处理方法
摘要：
本发明公开了一种酸再生文丘里后负压降低的处理方法，属于冷轧酸再生技术领域。该方法包括：向酸洗塔中加入脱盐水，脱盐水加入量为酸洗塔的进酸量的2-3.5%，本发明与需要切换运行水模式的方法相比，可以保证系统一直酸模式运行，并且提高再生酸产量2-3.5%，同时不会影响再生酸和氧化铁粉质量，有效杜绝由于频繁切换水模式造成的堵炉等事故。
摘要（英）：

The invention discloses a method used for reducing acid regenerating venture rear negative pressure, and belongs to the field of cold rolling acid regeneration technology. The method comprises a step of adding desalinized water into a pickling tower, wherein the amount of desalinized water is 2 to 3.5% of the amount of acid added into the pickling tower. Compared with a method in which it is needed to switch to run a water mode, the method of the invention is capable of ensuring that an acid mode is kept running by the system, and promoting recovered acid yield by 2 to 3.5%; meanwhile, the quality of recovered acid and the quality of iron oxide powder are not influenced, and accidents such as furnace blocking caused by frequent switching to the water mode are prevented effectively.
