Abstract
Przedmiotem zgłoszenia jest sposób oczyszczania gazów odlotowych z pieców do wypalania klinkieru z tlenków azotu, siarki i rtęci, który charakteryzuje się tym, że w procesie przemiału surowca uzyskuje się odpowiednią wilgotność, temperaturę i stopień zapylenia gazów znajdujących się w układzie wypalania a następnie poprzez reaktor oczyszczania gazów (7) wprowadza się do nich utleniacz w formie mocno zdyspergowanych kropel-mgły ponadto w reaktorze (7) przeprowadzana jest retencja oczyszczanych gazów z wprowadzonym utleniaczem w czasie co najmniej 5 sek a dodatkowe obniżenie emisji rtęci z oczyszczanych gazów uzyskuje się poprzez częściowe lub całkowite usuwanie pyłów z filtrów (8) oraz (10) powstałych po procesie końcowego odpylania i zwracanie ich do układu wypalania jako część mąki surowcowej a w przypadku wyższych stężeń rtęci częściowe lub całkowicie usuwane z układu wypalania poprzez by-pass. Zgłoszenie obejmuje także układ do oczyszczania gazów odlotowych z pieców do wypalania klinkieru z tlenków azotu, siarki i rtęci składający się z pieca (1), cyklonowego wymiennika ciepła (2), wentylatorów (3, 10) młynowni surowca (4), filtrów (9, 11), charakteryzujący się tym, że pomiędzy młynownią surowca (4) a filtrem końcowym (9) wprowadzony jest dodatkowy układ składający się z odpylacza gazów (5), reaktora oczyszczania gazów (7) oraz wentylatora (8).The subject of the application is a method of cleaning flue gases from clinker burning kilns from nitrogen oxides, sulfur and mercury, which is characterized by the fact that in the process of grinding the raw material appropriate humidity, temperature and degree of dusting of gases in the burnout system are obtained, and then through the purification reactor gases (7), an oxidant is introduced into them in the form of highly dispersed mist-drops, moreover, in the reactor (7), the retention of the purified gases with the introduced oxidant is carried out for at least 5 seconds, and an additional reduction of mercury emissions from the purified gases is achieved by partial or complete removing dust from filters (8) and (10) resulting from the final dedusting process and returning them to the firing system as part of the raw flour, and in the case of higher mercury concentrations, partially or completely removed from the firing system by bypass The application also covers a system for cleaning flue gases from clinker kilns from nitrogen oxides, sulfur and mercury consisting of a kiln (1), a cyclone heat exchanger (2), fans (3, 10), raw material mills (4), filters (9 , 11), characterized in that an additional system consisting of a gas dust separator (5), a gas purification reactor (7) and a fan (8) is introduced between the mill of the raw material (4) and the final filter (9).
