Zusammenfassung: | The invention relates to a water-saving type strip steel pickling line and a method capable of recycling hydrogen and without pumping and discharging acid mist. A steel strip is immersed in a water tank, and the lower ends of the end sealing plates arranged close to a water tank pressure roller in the acid tank direction and in sealed connection are inserted into the water in the water tank; the steel strip is immersed in a cleaning tank, the upper liquid surface of the immersed section in the acid tank direction and the upper plate and side plate of an overflow water sealing component form a pure space, and a water curtain is arranged in the space and mixed with the acid surface on the contact surface; two kinds of port sealing acid mist structures can totally seal the acid mist generated by the acid tank and permeating in the port to prevent escape. A 'wet-wire cluster type' dynamic sealing structure can totally mix the acid mist leaking from the gap formed by the roller diameter passing through the hat wal |
