1 Process System Reform
Through formulate specific scheme and organize installation teams to implement, adjust and train, the operation system can be optimized and improved and energy reduced.
2 Equipment upgrades Reform
Test the original equipment to find problems, and then formulate plan accordingly and organize installation to reach the purpose of upgrading the equipment and improve the efficiency, such as roller press, vertical mill, and ball mill’s efficiency improvement, cyclone, vertical mill classifier’s efficiency improvement, grate cooler’s upgrading etc.
3 Smoke Emission of Denitration and Desulfuration Reform
For denitration, “staged combusting+SNCR+LNB” way is used to reduce NOX of smoke, which can satisfy emission cap of cement industry. For desulfuration, since the cement raw material contains 70% CaCO3 and the smoke contains a little CaO, a kind of desulfuration catalyst is added in the certain positon of the preheater of the kiln end, which can make the concentration of SO2 decreased to 5~10 mg/Nm3.
4 Dust Control Reform (fugitive emission)
According to fugitive dust emission, dry fog dust suppression is used. Through spraying droplets of atomized water, most of the dust is wrapped in the spray water, becomes large particles and then drops.
