Description
85°С, подаваемой непосредственно из нижней части башни.85 ° C, served directly from the bottom of the tower.
Мелкодисперсный распыл серной кислоты способствует созданию высокоразвитой поверхиости контакта фаз и интенсивному его охлаждению.The fine spray of sulfuric acid contributes to the creation of a highly developed surface of the contact of the phases and its intensive cooling.
Увлекаемые газовыми потоками мелкодиспергированные капли серной кислоты поступают на вторую ступень башни, где осуш;ествл етс непосредственна конденсаци серной кислоты на поверхности этих капель. Охлаждение газа до температуры 160-220°С, соответствуюшей 80-95% конденсации , осуш;ествл ют охлажденной в холодильниках серной кислотой, подаваемой противотоком к газу. Втора ступень может быть полой, насадочной или трубчатой .The finely dispersed sulfuric acid droplets entrained in the gas streams enter the second stage of the tower, where they are dried, and there is a direct condensation of sulfuric acid on the surface of these droplets. Gas cooling to a temperature of 160–220 ° C, corresponding to 80–95% condensation, is dried; it is cooled with refrigerated sulfuric acid supplied countercurrent to gas. The second stage can be hollow, nozzle or tubular.
Треть ступень охлаждени до 40-80°С предназначена дл полного охлаждени газа и окончательной конденсации серной кислоты и вод ных паров, может быть выносной или смонтированной в этом же аппарате . Указанные услови конденсации обеспечивают получение крупнодисперсного тумана диаметром более 3-5 мкм и существенно уменьшают его количество.The third stage of cooling to 40-80 ° C is intended for complete cooling of the gas and the final condensation of sulfuric acid and water vapor, and can be remote or mounted in the same apparatus. These condensation conditions provide coarse mist with a diameter of more than 3-5 microns and significantly reduce its quantity.
Использование предлагаемого способа Using the proposed method
позвол ет исключить из схемы мокрые электрофильтры. Улавливание же небольшого количества крупнодисперсного тумана осуществл ют в волокнистых или пористых керамических фильтрах.allows to exclude wet electrostatic precipitators from the circuit. The capture of a small amount of coarse mist is carried out in fibrous or porous ceramic filters.
