Description

Technical Field

[0001] This utility model belongs to the technical field of continuous production system based on high-purity sulfuric acid co-production, and more specifically, it relates to a continuous production system based on high-purity sulfuric acid co-production. Background Technology

[0002] A continuous production system for high-purity sulfuric acid is an industrial production method that co-produces sulfuric acid with other byproducts (such as hydrogen chloride and nitric acid) through a continuous reaction process. This system achieves high purity sulfuric acid and high recovery rates of byproducts by optimizing reaction conditions, improving reaction efficiency, and controlling reaction temperature and pressure. Compared with traditional batch production, continuous production systems offer advantages such as higher production efficiency, reduced energy consumption, and reduced environmental pollution, and are widely used in industries such as chemical, metallurgical, and power generation.

[0003] Current continuous production systems based on the co-production of high-purity sulfuric acid store the produced high-purity sulfuric acid in storage tanks for later transportation. However, if air enters the storage tank during storage, the moisture in the air will react with the high-purity sulfuric acid to form sulfuric acid hydrate, resulting in a decrease in sulfuric acid concentration and affecting its purity. At the same time, the reaction of oxygen in the air with the high-purity sulfuric acid may also lead to the oxidation of sulfuric acid, producing byproducts that affect the quality of the sulfuric acid.

[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings, and provide a continuous production system based on high-purity sulfuric acid co-production, in order to achieve a more practical value. Utility Model Content
