[0002] Barium sulfate is an important inorganic salt, which is widely used in chemical, pharmaceutical, ceramic and other fields. In the production process of barium sulfate, desulfurization is a key step, which is of great significance for improving product quality and production efficiency.

[0003] Traditional desulfurization towers for barium sulfate production usually use a single tower or multiple towers in series for desulfurization treatment, but these methods have some problems. They require multiple devices to work together, resulting in high equipment investment costs, complex operation processes, cumbersome installation and difficult disassembly, and require multiple processes and complex operations to complete the desulfurization treatment, which brings certain difficulties to production. At the same time, a large amount of steam is required for heating and cooling, resulting in high energy consumption, which is not conducive to energy conservation and emission reduction. Therefore, a desulfurization tower for barium sulfate production with a dual-use layered structure is proposed. Utility Model Content
