Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of acid regeneration process, in particular to a regenerated acid recovery and collection pipeline. Background Art
[0002] In the process of "Spray Roasting Method for Regeneration of Hydrochloric Acid Waste Liquid", the regenerated hydrochloric acid produced by the acid regeneration station will be supplied to the pickling workshop after adding water. The acid regeneration station will produce a large amount of regenerated hydrochloric acid every month, which will flow directly from the acid unloading pipeline to the acid storage tank. Because the acid unloading pipeline is long and hydrochloric acid has a certain viscosity, a certain amount of hydrochloric acid will adhere to the inner wall of the acid unloading pipeline after each unloading of hydrochloric acid. The residual hydrochloric acid will flow back to the acid inlet pipe and cannot be received. It can only be diluted with water and discharged into the sewage pit, which will increase the burden of subsequent sewage treatment and increase the cost of use. Utility Model Content
