Environment-friendly copper strip pickling equipment

Abstract

The invention provides environment-friendly copper strip pickling equipment which comprises a pickling tank and a drying device, and a copper strip is subjected to pickling treatment after passing through the pickling tank and is dried after passing through the drying device; the drying device comprises a water absorption scraping brush structure, a heating structure, an air exhaust structure and a tail gas purification structure; the water absorbing and scraping structure absorbs the pickling solution on the outer wall of the copper strip and performs scraping and brushing; the heating structure is used for heating and drying a water absorbing part of the water absorbing and scraping structure, so that the absorbed pickling solution is volatilized; the air exhaust structure is used for sucking the volatilized pickling solution steam and conveying the volatilized pickling solution steam to the tail gas purification structure; the tail gas purification structure is used for absorbing, neutralizing and purifying the entering acid gas; the device is novel in structure, the copper strip can be subjected to acid pickling, the copper strip subjected to acid pickling is dried, waste gas generated in the drying process is purified, overall coherent machining is achieved, and environmental protection can be promoted.

Description

technical field [0001] The invention relates to the field of copper strip processing equipment, and more particularly, to an environment-friendly copper strip pickling equipment. Background technique [0002] After the pickling line is pickled, the surface of the copper strip has some water stains, and it needs to be dried before it can be wound. At present, the method of heating and drying is commonly used for drying. The secondary cleaning function makes the surface of the copper strip still have residual pickling solution water stains. Subsequent heating will cause the volatilization of the pickling solution, causing pollution to the outside air, and may also cause imprints on the surface of the copper strip, affecting product quality. Improve. SUMMARY OF THE INVENTION [0003] In order to overcome the defects of the prior art, the technical problem to be solved by the present invention is to propose an environmentally friendly copper strip pickling equipment, which ha...

[0002] After the pickling line is pickled, the surface of the copper strip has some water stains, and it needs to be dried before it can be wound. Currently, heating and drying is commonly used for drying, but because most copper strips do not have secondary The secondary cleaning function makes the surface of the copper strip still have residual pickling solution water stains. Subsequent heating will cause the volatilization of the pickling solution, pollute the external air, and may also cause marks on the surface of the copper strip, affecting product quality. Improve
