The invention discloses equipment for continuous acid leaching treatment of high silica glass fiber cloth. The equipment comprises an acid leaching slot; the acid leaching slot comprises a presoaking acid slot, a thermal acid slot I, a thermal acid slot II and a thermal acid slot III; the glass fiber cloth arranged on an unwinding machine enters the presoaking acid slot, the thermal acid slot I, the thermal acid slot II, the thermal acid slot III, a water washing slot I, a water washing slot II and a water washing slot III in sequence by a cloth feeding machine, pickling and washing are finished, the glass fiber cloth is dried and flattened by drying and flattening equipment, and is wound by a winding machine beside the drying and flattening equipment, and the production line operation is finished. The equipment is a piece of production line equipment, the content of SiO2 in the glass fiber cloth can be improved from 70% to be over 96% by controlling the process parameters through the process steps, the temperature resistance performance of grey cloth is improved to 100 DEG C, the continuous production line acid leaching production efficiency is high, the SiO2 content of obtained grey cloth is stable, the comprehensive performance of the product is greatly improved, and benefits are increased for an enterprise.
