The invention relates to waste acid and slurry combined feeding equipment. The waste acid and slurry combined feeding equipment comprises first waste acid guns, a second waste acid gun, an acid slurrygun, single lifting devices used for controlling the first waste acid guns to ascend and descend and a combined lifting device used for controlling the second waste acid gun to ascend and descend, controlling the acid slurry gun to ascend and descend and switching the second waste acid gun and the acid slurry gun, wherein the number of the first waste acid guns is two, the first waste acid guns correspond to the single lifting devices in a one-to-one mode, the first waste acid guns are connected with the corresponding single lifting devices, and the second waste acid gun and the acid slurry gun are connected with the combined lifting device. According to the waste acid and slurry combined feeding equipment, combined supply and real-time switching of waste acid and acid slurry can be realized, under the condition of complete acid production, two first waste acid guns and one second waste acid gun can be used for supplying the waste acid, and under the condition that the acid slurry needs to be treated, the acid slurry gun is used for replacing the second waste acid gun, so that the waste acid and the acid slurry are simultaneously supplied to a roasting furnace, synchronous resource treatment of the two media is completed, and the production operation efficiency is improved.
Description
technical field [0001] The invention belongs to the technical field of regeneration of waste acid by spray roasting method, and in particular relates to a combined feeding equipment of waste acid and mud. Background technique [0002] In the roasting furnace used in the waste acid regeneration process of the spray roasting method, the waste acid is sprayed in the form of mist through the acid gun, and after high-temperature thermal hydrolysis, regenerated acid and metal oxides are generated, and the acid gun needs to be supplied by the waste acid. material equipment to control. None of the existing spray-roasting waste acid regeneration units has the ability to treat acid sludge, and the method of using sludge to prepare slurry is fed into the roaster to make the roasting treatment of acid sludge possible. [0003] Since the output of acid mud is related to the pickling maintenance of iron and steel enterprises, the output varies greatly, and it does not have the continuity...
