V_A型触媒在富冶厂烟气制酸干法净化流程中试用结果表明,在吸砷、抗砷和强度诸方面,它均较V_1型触媒为优,以接触砷量计,已达到试用的预定目的。但由于烟气成分比较复杂,试用过程中发现SO_2的转化率波动很 V_A type catalyst in rich smelter flue gas acid dry purification process trial results show that in the absorption of arsenic, arsenic and strength aspects, it is better than the V_1 catalyst is better to contact the arsenic meter, has reached the trial Intended purpose However, due to the complexity of flue gas composition, the conversion of SO2 was found to be very volatile during the trial
