Problems solved by technology

[0002] The galvanized sheet should be sprayed with a passivation solution before it leaves the factory to prevent its oxidation and corrosion. The current method is to directly discharge the exhaust gas, which not only pollutes the environment, but also wastes energy. The existing drying equipment will leave liquid on the edge of the sheet after drying the galvanized sheet, and the galvanized sheet with the remaining liquid will enter the recycling In the rolling stage, the quality of galvanized sheet products is reduced, and the products are prone to rust

Abstract

The invention relates to galvanized sheet drying equipment and in particular relates to the galvanized sheet drying equipment used in a galvanization technology. Combustible waste gas is introduced into a combustion furnace to be subjected to secondary combustion, so that environmental pollution is prevented while energy is saved; a cold air purging device is arranged at the front end of a drying case along the flowing direction of a galvanized sheet, the edge of the galvanized sheet is blow-dried in advance by virtue of two air outlets, corresponding to the two edge positions of the galvanized sheet, of the cold air purging device, then the dried sheet which is not rolled up keeps dry by virtue of the drying case, drying quality is improved, no liquid is remained at the edge of the sheet, and the sheet can not rust.
