Abstract:
     The said method includes the following steps: lead fume containing sulfur oxide into spray dryer; lead atomized ammonia into spray dryer so as to make ammonia water and sulfur oxide contact and react to produce ammonium sulfate; exhaust reacted fume from the spray dryer to deduster, where the ammonia sulfate powder is separated from fume and collected; and magnetizing powder to obtain magnetized fertilizer. The said equipment includes spray dryer, ammonia water atomizer inside the spray dryer, deduster down the spray dryer and magnetizer.
