Abstract
Przedstawiono sposób oczyszczania gazów spalinowych w instalacjach przemysłowych, obejmujący wstępne usuwanie cząstek stałych do poziomu 50 — 150 mg/m3 gazów, a następnie kontaktowanie gazów z wodnym roztworem amoniaku o stężeniu od 15% do 25%, charakteryzuje się tym, że z gazów spalinowych o temperaturze 150 - 180°C usuwa się cząstki stałe, a następnie wprowadza się gaz w kierunku reaktora (2) i przed osiągnięciem wlotu reaktora dozuje się do tego gazu, współprądowo, mający postać kropelek roztwór amoniaku o temperaturze od 0 do 30°C, a w przestrzeni reaktora także współprądowo, do gazów wtryskuje się wodę technologiczną o temperaturze wynoszącej od 0 do 30°C, w ilości od 20 do 50 g wody na 1 m3 oczyszczanych suchych gazów spalinowych, przy czym w reaktorze tworzą się, zawieszone w gazach, stałe cząstki siarczanu amonu (NH4)2SO4, które oddziela się z użyciem filtrów cząstek stałych, a oczyszczone gazy spalinowe poprzez wentylator wyciągowy wyrzucane są do komina i opuszczają instalację.The paper presents a method of cleaning flue gases in industrial installations, including the initial removal of solid particles to the level of 50 - 150 mg / m3 of gases, and then contacting the gases with an aqueous solution of ammonia with a concentration of 15% to 25%, characterized by the fact that from flue gases with At a temperature of 150 - 180 ° C, solid particles are removed, then gas is introduced in the direction of the reactor (2) and, before reaching the reactor inlet, a downstream ammonia solution in the form of droplets at a temperature of 0 to 30 ° C, and in in the reactor space, also co-current, process water at a temperature of 0 to 30 ° C is injected into the gases, in an amount of 20 to 50 g of water per 1 m3 of dry flue gas to be cleaned, and solid particles suspended in the gases are formed in the reactor ammonium sulphate (NH4) 2SO4, which is separated with the use of particulate filters, and the cleaned flue gases are thrown into the chimney through the exhaust fan and leave the installation ę.
