AI Technical Summary
When existing high-purity perchloric acid continuous preparation equipment stops production, the remaining raw materials in the metering pump are prone to crystallization and precipitation, and component stratification, which leads to blockage of the pump body and subsequent channels, affecting reaction stability and product purity.
A three-way valve is installed at the output end of the metering pump to transport the retained raw materials to the retained raw material processing tank. The raw material processing component is used for filtration and mixing. Combined with the grinding and reflux functions of the crystallization processing component, crystallization precipitation is eliminated, ensuring accurate feed concentration and ratio.
It effectively avoids blockage of the pump body and subsequent channels, ensures the stability of feed concentration and ratio, and improves the quality and purity of high-purity perchloric acid.
