| titleOfInvention | Method and system for regenerating and recycling glass thinning waste acid liquor |
| abstract | The invention provides a method and a system for regenerating and recycling glass thinning waste acid liquor, wherein the method comprises the following steps: under the action of concentrated sulfuric acid, hydrogen chloride, silicon tetrafluoride, hydrogen fluoride and boron trifluoride escape in a gas state; condensing the hydrogen chloride, silicon tetrafluoride, hydrogen fluoride and boron trifluoride gas to obtain hydrogen fluoride liquid; uncondensed gas enters BF 3 Auxiliary agent for absorption tower to absorb BF 3 To obtain boron trifluoride-assistant complex solution; enabling the unabsorbed gas to enter an HCl compressor to compress the HCl gas into liquid HCl; uncompressed gas into SiF 4 An absorption tower. By using the method, the recovery rate of hydrofluoric acid (HF) contained in the glass thinning waste acid liquid is more than or equal to 95 percent; the recovery rate of hydrochloric acid (HCl) is more than or equal to 93 percent. All effective components in the waste acid are recycled, the treatment cost is low, the recovery efficiency is high, and the method is suitable for industrial popularization and application. |
