Abstract
The invention provides a condensing unit used for modular wet process sulfuric acid production. The condensing unit used for the modular wet process sulfuric acid production comprises a bottom kerf module, multiple condensation modules, a mist eliminating module and a gas circuit connecting module. The condensing unit used for the modular wet process sulfuric acid production adopts modular design, standardization of manufacturing of the condensing unit can be realized by increasing or decreasing quantity of related condensation modules according to different requirements, further manufacturing cost is reduced, parts among the modules are sealed by adopting dual sealing structures, sealing property among the modules can be effectively guaranteed, acid gas leakage is avoided, safety of the condensing unit is improved, vertical link between upper and lower modules is also facilitated, and overall smooth running of the condensing unit is guaranteed.
Description
technical field [0001] The invention belongs to the field of acid gas treatment devices, and in particular relates to a modular wet-process condensing device for sulfuric acid production. Background technique [0002] According to the literature (Sulfuric Acid Industry, 1998(2), 23-40): a typical wet-process acid condenser, the SO-containing 3 、H 2 The acid gas temperature of O can reach up to 300°C, and the acid gas enters the sulfuric acid condenser from the bottom. In the sulfuric acid condenser, as the temperature of the acid gas decreases, the SO 3 Gas and H 2 O steam undergoes hydration reaction to generate sulfuric acid steam, and the sulfuric acid steam is condensed into 93-98% concentrated sulfuric acid. Its reaction formula is as follows: [0003] [0004] [0005] Concentrated sulfuric acid is collected at the bottom of the condenser and discharged, and the tail gas is discharged from the top outlet of the sulfuric acid condenser at a temperature of 90-1...
