Problems solved by technology
[0002] At present, the flue gas temperature of the domestic high-temperature fuel-fired tunnel kiln used for burning refractory products is generally above 300°C, and the flue gas components are mainly sulfides and nitrogen oxides. The flue gas is directly discharged through the chimney without treatment, which is harmful to the environment. create pollution
Existing devices for tunnel kiln flue gas treatment, for example, the application number is 201020127990.2, and the name of the invention is a tunnel kiln flue gas heat exchange, dust removal and emission reduction device. The disclosed treatment method is to first process the high temperature flue gas discharged from the tunnel kiln Heat exchange and cooling, and then introduce it into the spray room for spray washing. This treatment method does not purify the flue gas thoroughly, and does not separately treat the dust, sulfide, and nitrogen oxides in the flue gas
