The prior method for removing rust on the surface of a steel plate is generally an acid pickling rust removal method. The principle is that the chemical reaction between acid in the acid washing solution and metal oxide is utilized to dissolve the metal oxide, so as to remove the rust and dirt on the surface of the steel. However, after the steel plate is pickled and derusted, a large amount of clear water is required for cleaning and passivating, and a large amount of waste water, waste acid and acid mist formed by the steel plate cause environmental pollution. If not properly treated, the metal surface can be over-etched to form pits. Under the severe situation of haze, river pollution and land pollution on ten surfaces in various places and the environmental protection pressure of public opinion, the national strong pollution control has more and more strong decisions. For enterprises still adopting the pickling process for rust removal, the environmental protection pressure is getting larger and larger. The method selects new environment-friendly derusting process equipment as soon as possible, and is in the very beginning.
