Abstract

PURPOSE:To highly concentrate sulfuric acid at a high recovering rate by slightly evacuating heated tubes and preventing the countercurrent contact of the feed soln. and steam to prevent acid mist from mixing into steam and steam from leaking to the outside. CONSTITUTION:Starting material sulfuric acid is allowed to uniformly flow out of feed pipe 7 toward the whole circumference of lower end trumpet-shaped part 5a of circular part 5c of outer tube 5b of the lower double tube of each dispersion tube 5 through part 5c and to flow down each heated tube 2 from circular slits 6 in the form of a thin film. During this time, the acid is heated with combustion gas fed into heating furnace 1 from burners 9 to evaporate water contained, and the concd. sulfuric acid is recovered in storage tank 3. On the other hand, the steam is introduced into steam header 8 kept under slightly reduced pressure from each part 5a through the upper part of pipe 5.
