Seek advice on removing F and Cl using multi-chamber furnaces in wet zinc smelting
Thread Content
1. The multi-chamber furnace used in our facility does not achieve very good results in removing F and Cl; the temperature is around 700 degrees, plus or minus 20 degrees. There are 12 layers, with a slight negative pressure in each layer. The furnace needs to be cleaned 1–2 times per shift, with each cleaning session lasting 20–40 minutes. Could someone please advise on how to improve the efficiency of removal? 2. ZnO usually appears grayish-white when it enters the multi-chamber furnace, but why does it change color in some of the layers, such as turning light green? Please give some advice: handshake :funk:
Please describe your dust collection situation, such as the temperature of the smoke and dust entering the dust collection chamber, the material of the dust collection bags, as well as the volume of flue gas and the dust collection area, to determine whether they are compatible.
The dust is first cooled by surface cooling before undergoing pulse dust removal; the inlet temperatures are 300–500 degrees and 150 degrees respectively. What he means is that the F and Cl gases removed have not been completely expelled?
Hybrid zinc oxide changes color under different temperatures and atmospheres.
Bro, could you please clarify again which element, or roughly at what temperature, turns what color? Thank you so much! !
It is necessary to control the appropriate roasting time and temperature, while also paying attention to stable feeding.
