[0002] Hydrochloric acid is commonly known as hydrochloric acid, which is an aqueous solution of hydrogen chloride gas. Hydrochloric acid is a colorless liquid (industrial hydrochloric acid will be slightly yellow due to impurities such as ferric salts), corrosive, and is an aqueous solution of hydrogen chloride. It is commonly used in industry It is used for pickling the surface of metal parts and cleaning oxides. A large amount of waste hydrochloric acid solution is often produced during use. If these pickling waste solutions are not treated and discharged directly, it will not only waste resources, but also bring serious environmental problems. pollution, but at present, hydrochloric acid recovery is often realized by solvent extraction through the reaction of medicinal liquid and waste hydrochloric acid solution.

The invention relates to the technical field of waste hydrochloric acid treatment, and relates to a method for recycling and reusing industrial waste hydrochloric acid, which uses a recovery treatment equipment, the equipment storage box, a sedimentation tank, a fixed plate, a delivery pipe, a water pump, a connecting pipe, and a driving motor , auxiliary cover, treatment tank and filter box, the waste hydrochloric acid solution is transported to the sedimentation tank through the delivery pipe, and precipitated in the sedimentation tank, and then the water pump is used to pump the waste hydrochloric acid solution precipitated in the sedimentation tank into the connecting pipe, and then It is transported to the treatment tank along the auxiliary cover, and is recycled, and then the treated waste hydrochloric acid enters the inside of the filter box, is filtered by the filter box, and is recycled into the storage tank, and then the waste hydrochloric acid is recycled. By using it, the multi-stage treatment function of waste hydrochloric acid liquid is realized, and the treatment effect is improved.
