Embodiment 1
[0027] A method for recycling residual acid from waste lead-acid batteries, comprising the following steps:
[0028] Step 1: Put the waste lead-acid battery into the crushing equipment for crushing, and screen the battery fragments discharged from the crushing device to obtain the waste acid solution;
[0029] Step 2: Add additives to the waste acid solution, pass the waste acid solution mixed with lead plaster and additives into the primary sedimentation tank, and let it settle for 1 to 2 hours;
[0030] Step 3: The waste acid solution in step 2 is discharged from the upper part of the sedimentation tank into the secondary filter tank, and the filtrate enters the secondary filter tank for grid filtration to remove active substances and obtain the sulfuric acid electrolyte for initial treatment;
[0031] Step 4: Inject the initial treatment sulfuric acid electrolyte in step 3 into the tertiary osmosis tank, add flocculant to the filtrate, stir and mix well, then let it settle ...
