一、废旧蓄电池的预处理废旧蓄电池中含有多种有用成分,为了回收其中的有用组分,国外发达国家都要对废旧蓄电池进行预处理。 1.意大利Engetic公司首先压碎废旧蓄电池放出残酸,收集备用,也可送中和槽生产Na_2SO_4,再用筛分机加水把碎块分成大、中块及细料浆三部分。大块返回压碎机再压碎;细料浆送中和槽用Na_2CO_3中和残酸,并使PbSO_4转成PbCO_3。中和
First, the pre-treatment of waste batteries Waste batteries contain a variety of useful components, in order to recover the useful components of which developed countries have to pre-waste batteries. 1. Italy Engetic company first crush the waste battery release residual acid, collected spare, can also send neutralization tank production Na_2SO_4, and then use sieving machine water to divide the pieces into large, medium and fine slurry of three parts. The chunks are returned to the crusher for crushing; the fine slurry is sent to the neutralization tank to neutralize the residual acid with Na_2CO_3 and convert PbSO_4 to PbCO_3. neutralize
