Abstract
The invention relates to an environment-friendly recycling method for a waste lead-acid storage battery. The environment-friendly recycling method comprises the following steps: (1) punching a hole in the bottom of the waste lead-acid storage battery with a shell to discharge waste acid, collecting the waste acid by using a storage tank, delivering the waste acid in a sulphuric acid production workshop for producing sulphuric acid, performing primary crushing on the lead-acid storage battery by using a punching machine, further crushing the lead-acid storage battery by using an alligator-type crusher, and performing fine grinding by using a ball-grinding mill; (2) sorting the lead-acid storage battery which is treated in the step (1) by using a special tower-type weight sorter to obtain a light-weight material, an intermediate-weight material and a heavy-weight material; (3) calcining the light-weight material and the intermediate-weight material which are obtained in the step (2) for 3 to 6 hours at 500 to 600 DEG C; (4) mixing ultrafine lead powder obtained in the step (3) and industrial coarse lead powder. According to the environment-friendly recycling method, a lead-containing material is used for preparing active material slurry for negative plate coating paste for the lead-acid storage battery, so that the recovery utilization rate of the lead is remarkably improved, and the economic benefit is improved.

Application way.
Background technology
Plumbic acid stores old and useless battery and is formed by positive/negative plate, dividing plate, housing, electrolyte and wiring pile are first-class, and waste and old lead stores
Containing lead and compound thereof in battery, possibly together with electrolyte solutions such as metal and acid such as hydrargyrum, cadmium, chromium and manganese, once enter people
Body, the insulting nervous system of meeting, hemopoietic function and kidney etc., the heavy metal that the lead-acid accumulator arbitrarily thrown is decomposed contains
Toxic waste liquid, can destroy ecological balance, be detrimental to health.China has produced 300,000 tons of lead-acid accumulators, usual lead every year
Acid stores old and useless battery and reclaims the lead mud produced, and main component is lead sulfate, lead oxide, Lead oxide brown and sulphuric acid, by thermal decomposition
May separate out monomer lead, but the decomposition temperature of lead sulfate is up to more than 900 degree, catabolite vulcanized lead is also required in higher temperatures
Replacing under degree, the method not only results in environmental pollution, and energy consumption is high, and the response rate of lead is relatively low, is about 80%.
Summary of the invention
It is an object of the invention to provide a kind of method storing old and useless battery recovery lead from plumbic acid, to solve prior art general
Plumbic acid stores that the energy consumption existed when old and useless battery reclaims lead is high, the response rate is low and causes environmental pollution and the deficiency that exists.
To achieve these goals, technical scheme is as follows.
A kind of plumbic acid stores the environmental protection reuse method of old and useless battery, comprises the following steps:
(1) plumbic acid of band shell is stored old and useless battery bear and discharge spent acid, this spent acid is collected with accumulator tank and sends into Sulphuric acid
Workshop Sulphuric acid, then carries out lead-acid accumulator punch press the most broken, then crushes further with alligator, then use
Ball mill fine grinding；
(2) the lead-acid accumulator special tower gravity classifier after step (1) being processed sorts, it is thus achieved that light material,
Middle pledge material and heavier feeds；
(3) light material obtained in step (2) and heavier feeds are calcined 3～6h under conditions of 500～600 DEG C, it is thus achieved that
Superfine lead powder；
(4) superfine lead powder that step (3) obtains is mixed with industrial crude Hydrocerussitum (Ceruse), add water and sulphuric acid, after being uniformly mixed,
Obtaining active substance slip, wherein, the mass ratio of superfine lead powder, industrial crude Hydrocerussitum (Ceruse), water and sulphuric acid is 1:3:6:3.
In described step (1), for the first time broken granularity is 200～300mm, the most broken after granularity be 60～
100mm, after fine grinding, granularity is 10～15mm.
Described light material is the mixture such as epoxy resin particle and plastics, and middle pledge material is lead and metal, weight
Pledge material is the mixture of lead, lead oxide, Lead oxide brown and lead sulfate.
This beneficial effect of the invention is: after the present invention is by carrying out lead-acid accumulator twice crushing, then carry out fine grinding,
The recycling of follow-up lead can be effectively facilitated, be used for leaded material preparing the negative plate cream being used for lead-acid accumulator
Active substance slip, significantly improve the recovery utilization rate of lead, improve economic benefit.
