[0018] 1. In the dissolution reactor, the waste residue is crushed and crushed, and then reacted with reagents such as sulfuric acid. After the reaction mixture is separated, the waste residue is collected and can be further extracted to extract valuable components, thus realizing the recycling and reuse of resources. In the alkali recovery reactor, the product after the reaction with carbon dioxide is treated and the arsenic-containing liquid is collected, providing a way to extract useful substances from the arsenic-containing liquid in the future, thereby improving the comprehensive utilization rate of resources.

[0019] 2. In the dissolution reactor, the crushing mechanism driven by the hydraulic cylinder crushes the arsenic-containing waste residue, and the crushing mechanism on the right further pulverizes the waste residue. The entire process requires no manual operation. In the alkali recovery reactor, the gas-liquid agitator automatically stirs the liquid to fully react with carbon dioxide. When a certain pH value is reached, the valve automatically opens to separate the solid and liquid, reducing manual monitoring and operation. In the high-pressure autoclave, heating, stirring, and the coarse screen group intercepting floating and suspended matter are all carried out automatically, reducing labor intensity and improving the treatment efficiency of arsenic-containing waste residue.
