实施本发明的不锈钢高效清洗装置及方法，具有以下有益效果：The stainless steel high-efficiency cleaning device and method of the present invention has the following beneficial effects:
1、超声波可强化带钢的电解、酸洗以及漂洗工艺。带钢超声清洗工艺，利用超声波使带钢附近的液体发生剧烈震荡，液体内部处于压力瞬间减少增大的循环中，在压力突然减小时，液体内部会形成许多高度真空气穴，压力突然增大而被压迫产生冲击波。这些冲击波作用在带钢表面，使带钢表面的污染物剥离，起到“无刷强效刷洗”的效果；同时还有升温、搅拌作用，强化传质，有利于带钢清洗，从而大大促进清洗的进行。1. Ultrasonic can strengthen the electrolysis, pickling and rinsing process of strip steel. The strip steel ultrasonic cleaning process uses ultrasonic waves to cause the liquid near the strip to vibrate violently. The pressure inside the liquid is in a cycle of instantaneous decrease and increase of pressure. When the pressure suddenly decreases, many high vacuum air pockets are formed in the liquid, and the pressure suddenly increases. And being oppressed produces shock waves. These shock waves act on the surface of the strip steel to peel off the contaminants on the surface of the strip, which has the effect of "brushless and powerful scrubbing"; at the same time, it also has the effect of heating and stirring to strengthen mass transfer, which is beneficial to strip cleaning, thereby greatly promoting The cleaning is carried out.
2、热轧不锈钢表面的氧化物较为粗大且厚，同时热轧退火酸洗后产品还要后续处理，所以在第一阶段采用热H 2SO 4方式就可满足要求，第二阶段采用混酸酸洗；而对于冷轧不锈钢，其表面氧化物较薄，但表面质量要求比热轧退火酸洗产品高，所以采用电解Na 2SO 4方式；对于冷轧铁素体不锈钢而言，第二阶段采用电解HNO 3。为了满足不同钢种、冷热轧不锈钢的酸洗，不锈钢酸洗采用通用的槽体结构，槽体结构根据工艺切换功能。 2. The oxide on the surface of hot-rolled stainless steel is relatively coarse and thick. At the same time, the product needs to be processed after hot-rolling, annealing and pickling. Therefore, the hot H 2 SO 4 method can meet the requirements in the first stage, and the mixed acid in the second stage For cold-rolled stainless steel, the surface oxide is thinner, but the surface quality requirement is higher than that of hot-rolled annealing pickling products, so the electrolytic Na 2 SO 4 method is used; for cold-rolled ferritic stainless steel, the second stage Use electrolytic HNO 3 . In order to meet the pickling of different steel grades and cold and hot rolled stainless steels, stainless steel pickling adopts a general tank structure, and the tank structure switches functions according to the process.
3、本发明适用于不同厚度、运行速度、冷热轧不锈钢的工业化连续清洗；本发明首次实现超声强化电解、酸洗和漂洗，利用超声的冲击波达到快速清洗目的，缓解不锈钢酸洗压力，显著提高清洗效率、降低环保压力。3. The present invention is suitable for industrialized continuous cleaning of stainless steel of different thicknesses, operating speeds, and cold and hot rolled; the present invention realizes ultrasonic enhanced electrolysis, pickling and rinsing for the first time, and uses ultrasonic shock waves to achieve the purpose of rapid cleaning and relieve the pressure of stainless steel pickling, which is significantly Improve cleaning efficiency and reduce environmental pressure.
