Изобретение относитс к очистке дымовьсс газов, предназначено дл использовани , например, на тепловых электростанци х дл очистки серосодержащих дымовых газов с одновременным получением серной кислоты.The invention relates to the purification of fume gases, intended for use, for example, in thermal power plants for the purification of sulfur-containing flue gases with simultaneous production of sulfuric acid.
Известен сухой способ очист дьиловых газов котельного агрегата, заключающийс в сухом отделении золы,последующем каталитическом окислении содержащегос в газах S02 до БОз и охлаждении газов перед электростатическим улавливанием образовавшихс паров серной кислоты 1).A dry method is known for purifying boiler gas from a boiler unit, consisting in dry ash separation, subsequent catalytic oxidation of gas-containing S02 to BOz and cooling of the gases before electrostatic capture of the sulfuric acid vapor formed 1).
Известный способ не обеспечивае достаточно надежной и экономичной очистки дымовых газов, котельного агрегата, так как предусматривает отвод газов от котлоагрегата при температуре пор дка 500-600 с, что приводит к черзмерно т желым услови м работы электрофильтра и требует реконструкции котельного агрегата.The known method does not provide sufficiently reliable and cost-effective cleaning of flue gases of the boiler unit, since it involves the removal of gases from the boiler at a temperature of about 500-600 s, which leads to excessively hard conditions of the electrostatic precipitator and requires reconstruction of the boiler unit.
Цель изобретени - повышение надежности очистки дымовых газов котлоагрегата, а также повышение экономичности процесса очистки.The purpose of the invention is to improve the reliability of cleaning of flue gases of the boiler, as well as improving the efficiency of the cleaning process.
Указанна цель достигаетс тем, что сухое отделение золы выполн ют при 130-170С, а перед каталитическим окислением их нагревают до температуры , при которой возможно каталитическое окисление SOj до SOj.This goal is achieved by the fact that the dry ash separation is performed at 130-170 ° C, and before catalytic oxidation, they are heated to a temperature at which catalytic oxidation of SOj to SOj is possible.
Кроме того, перед каталитическим окислением газы частично нагревают их же теплом, отбираемьм в In addition, before catalytic oxidation, gases are partially heated by their own heat, which is taken in

На чертеже изображена технологи5 ческа схема, иллюстрирующа реализацию описываемого способа.The drawing is a technological diagram illustrating the implementation of the described method.
Дымовые газы, прошедшие весь тракт котлоагрегата 1 (в tOM числе регенеративный воздухоподогрева0 тель 2 и электрофильтр котельного агрегата 3), отбирают перед дымовой трубой дымососом 4 котлоагрегата 1 и подают в специальный регенеративный подогреватель 5 дл подогрева газов со 130-170 до 350-480°С Flue gases that have passed the entire path of the boiler unit 1 (including tOM regenerative air heater 2 and electric precipitator of the boiler unit 3) are taken before the chimney with smoke exhauster 4 boiler unit 1 and are fed into a special regenerative heater 5 for heating gases from 130-170 to 350-480 WITH
