An intelligent purification and recovery device for sulfuric acid

Abstract

The invention belongs to the technical field of sulfuric acid recovery, in particular to an intelligent purification and recovery device of sulfuric acid. The intelligent purification and recovery device of sulfuric acid comprises a base, a filter box, a primary impurity removal box, a secondary impurity removal box and a recovery treatment box; the filter box and the recovery treatment box are respectively arranged at two sides of the top of the base, and the filter box and the recovery treatment box are communicated through a first electromagnetic valve; the inside of the filter box is positioned on a vertical midline and is rotationally connected with a rotating shaft, and a first friction plate and a second friction plate are arranged on the inner wall of the filter box, and a controller is arranged at the top of the filter box, and a motor is arranged at the top of the filter box, and the motor is in transmission connection with the rotating shaft; the first friction plate and thesecond friction plate are symmetrically arranged by taking the vertical middle line of the filter box as a reference; the primary impurity removal box and the secondary impurity removal box are arranged on the rotating shaft. According to the invention, the sulfuric acid waste liquid can be subjected to intelligent multiple impurity removal, and the impurity removal quality of the sulfuric acid waste liquid is improved, and the impurity removal module is utilized to improve the solid-liquid separation efficiency, and the cleaning of solid impurities is facilitated.

Description

technical field [0001] The invention belongs to the technical field of sulfuric acid recovery, in particular to an intelligent purification and recovery device for sulfuric acid. Background technique [0002] In industrial production, waste acid is produced in the process of nitration, esterification, sulfonation, alkylation, catalysis and gas drying of organic matter, or in the process of titanium dioxide production, steel pickling and gas drying. With the continuous growth of sulfuric acid consumption, the amount of domestic industrial waste sulfuric acid is also increasing year by year, and the recycling of waste sulfuric acid has also attracted more and more attention. In the recovery process of waste sulfuric acid, it is usually necessary to purify the waste sulfuric acid, first remove the impurities in the waste sulfuric acid, and then perform subsequent steps to obtain sulfuric acid with low impurity content for reuse. [0003] There are also some technical solutions...

AI Technical Summary

Problems solved by technology

However, when sulfuric acid waste liquid is removed from sulfuric acid waste liquid in this type of sulfuric acid recovery equipment, sulfuric acid waste liquid remains in the filtered solid impurities, which reduces the recovery of sulfuric acid waste liquid, and the residual sulfuric acid waste liquid reduces the labor cost. The safety factor of cleaning solid impurities, and wet solid impurities are not convenient for manual cleaning, which increases the workload
