Description

Technical Field

[0001] The utility model belongs to the technical field of waste sulfuric acid treatment, and particularly relates to a device for treating process waste sulfuric acid. Background Art

[0002] Waste sulfuric acid, commonly known as waste acid, is produced in industrial production in the processes of nitration, esterification, sulfonation, alkylation, catalysis and gas drying of organic matter, or in the processes of titanium dioxide production, steel pickling, etc. The waste acid solution contains substances such as metal salt ions and organic molecules according to the waste acid produced in different processes. If these substances are discharged directly, they will seriously pollute the environment. In addition, the metal salt ions have a strong recycling value, and their discharge will also cause a waste of resources, thereby increasing production costs.

Through the device, the waste sulfuric acid is filtered through precipitation and heated for distillation, and the recovered concentrated sulfuric acid reacts with aluminum hydroxide to generate aluminum sulfate, which solves the problem of waste sulfuric acid treatment on the one hand, and turns waste sulfuric acid into treasure and becomes a flocculant that can be used for industrial wastewater treatment on the other hand; in addition, the five-layer structure of the filtering device enhances the filtering efficiency on the one hand, and reduces the sulfuric acid recoil on the other hand.
