Embodiment 1
[0038] see Figure 1-9 Shown, a kind of processing method of regenerating and reclaiming sulfuric acid from lead-acid battery recycling waste acid, specifically comprises the following steps:
[0039] Step 1, send the waste polluted acid recovered from the lead-acid battery into the recovery box 10 through the feed pipe 107, connect the positive and negative poles of the power supply to the electrode assemblies at the front and back of the recovery box 10, and utilize the lead recovery plate 102 of the power supply to The lead in the waste sewage acid is reclaimed, and the lead in the waste sewage acid is adsorbed on the surface of the lead recovery plate 102, and the waste sewage acid processed through the lead recovery process inside the recovery box 10 is pumped into the preheating box 20 by the material pump 109;
[0040] Step 2, the waste acid enters the inside of the retort 401 through the feed pipe 302, and the heater 403 inside the heating frame 402 is used to heat the...
