Title:
ENERGY-SAVING AND ENVIRONMENT-FRIENDLY PICKLING DEVICE AND STRIP TREATMENT SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/035837
Kind Code:
A1
Abstract:
An energy-saving and environment-friendly pickling device and a strip treatment system using the energy-saving and environment-friendly pickling device. The pickling device comprises a pickling tank (102); at least one end of the pickling tank (102) is a liquid isolation end (103), the liquid isolation end (103) is provided with a bearing dam (1031) and a liquid blocking dam (1032), the bearing dam (1031) extends upwards from the tank bottom, the liquid blocking dam (1032) extends downwards from the tank top, the bearing dam (1031) and the liquid blocking dam (1032) respectively extend to a position near a strip moving channel, and the strip can pass through a gap between the two dams; or, the gap between the bearing dam (1031) and the liquid blocking dam (1032) is smaller than the thickness of the strip, and the bearing dam (1031) and/or the liquid blocking dam (1032) are/is elastic dams. By providing the liquid isolation end composed of the bearing dam (1031) and the liquid blocking dam (1032), high-speed jet flow does not need to be used for performing liquid sealing on acid liquid at the two ends of the pickling tank (102) any more, a large amount of acid fog cannot be generated, and acid consumption and the cost of subsequent acid fog treatment are reduced.
