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 sour gas treatment devices, and particularly relates to a modularized wet-process condensation device for producing sulfuric acid. Background technique [0002] According to the description of the literature (Sulfuric Acid Industry, 1998(2), 23~40): a typical condenser for wet acid production, the SO content entering the sulfuric acid condenser 3 , H 2 The temperature of the acid gas of O can reach up to 300℃. The acid gas enters the sulfuric acid condenser from the bottom. In the sulfuric acid condenser, as the temperature of the acid gas decreases, SO 3 Gas and H 2 O steam hydrates to generate sulfuric acid vapor, and the sulfuric acid vapor is condensed into 93-98% concentrated sulfuric acid. The reaction formula is as follows: [0003] [0004] [0005] The concentrated sulfuric acid is collected and discharged at the bottom of the condenser, and the tail gas is discharged from the top outlet of the sulfuric acid cond...
