Description

Technical Field

[0001] The utility model relates to the technical field of preliminary treatment devices for sulfuric acid wastewater, in particular to a preliminary reaction device for recycling sulfuric acid wastewater. Background Art

[0002] Sulfuric acid is an inorganic compound with the chemical formula H2SO4. It is the most important oxygen-containing acid of sulfur. Pure sulfuric acid is a colorless oily liquid that crystallizes at 10.36°C. It is usually produced in the form of aqueous solutions of various concentrations using the tower method and contact method. However, a large amount of sulfuric acid wastewater is generated during the production of sulfuric acid, which requires treatment equipment to treat it.

[0003] The existing preliminary reaction device for recycling sulfuric acid wastewater accelerates the reaction rate between the reagent and the sulfuric acid wastewater by stirring during use, so as to achieve preliminary treatment of the sulfuric acid wastewater. In the above method, during the stirring process, the sulfuric acid wastewater makes a circular motion in the reaction tank, and there is no relative motion between the layers, which leads to low stirring efficiency and poor stirring effect. Therefore, a preliminary reaction device for recycling sulfuric acid wastewater is urgently needed to solve the above problems. Utility Model Content

[0013] Beneficial technical effects of the utility model:

During the stirring process of sulfuric acid waste water, the stirring rod follows the turntable to make a circular motion on the one hand, and reciprocates on the other hand under the action of the electric slide rail and the slider.
