Gold smelting roasting flue gas spray cooling tower
Thread Content
The paper "Recovery of Arsenic in Gold Smelting and Roasting Flue Gas" mentions the spray cooling tower. Does anyone know about it or have designed it? I hope to give guidance!
Spray directly at this temperature? Is it better to use a waste heat boiler or GGH heat exchanger?
There are many things to consider in this flue gas spray cooling tower. Usually it is multi-layer spray. When it drops to 350 degrees, is it denitrification?
350 for dust removal, 390 for denitrification, 190 for denitrification, and 160 for desulfurization? It's better to waste the pot
Of course, it is better to recover waste heat, and using spray is only a temporary measure. We are smelting flue gas, collecting dust and then making acid to produce sulfuric acid. Thanks for the reply!
The quench tower can accurately control the temperature of entering electrostatic dust, increase the latent heat of acid production, increase the purification load, and pay attention to heat transfer.
According to the description, it seems like a quench tower. The chlorinated flue gas is spray-quenched from 7-800 degrees to about 350 degrees. One is the material problem of the tower, the composition of the flue gas, mixed acid is formed after spraying, and the range of material selection is narrow. There is currently no good solution. Second, the problem of latent heat will cause serious problems if it cannot be taken out.
