Abstract
The invention discloses a recovery method of a waste lead-acid storage battery separator. The recovery method of the waste lead-acid storage battery separator comprises the following steps: a cleaning the battery separator with a cleanout fluid; b baking the cleaned battery separator; c stripping and slicing the baked battery separator; and d grinding the stripped and sliced battery separator. Recovery is carried out through the method, so that the cost of treating the battery separator can be reduced; and meanwhile, certain economic benefits can also be brought through recycling.
Description
Technical field
The present invention relates to cell art, particularly relate to a kind of recovery method of waste and old lead acid accumulator dividing plate.
Background technology
Old and useless battery reclaims and usually can first be decomposed, and then sorts out, and have multi-products in after battery decomposes, its median septum is exactly one of them.Because of on its dividing plate after battery decomposes still containing the harmful substance such as heavy metal, therefore need to carry out unifying process, preventing pollution environment.And the mode of process usually is at present burned, can dispose waste and old dividing plate though burn, cost is high, and wastes resource, fails to recycle.
Summary of the invention
The technical problem to be solved in the present invention is to provide the recovery method of the low waste and old lead acid accumulator dividing plate of a kind of cost.
For solving the problem, the invention provides a kind of recovery method of waste and old lead acid accumulator dividing plate, comprising the following steps:
A: clean battery separator with cleaning fluid;
B: cleaned battery separator is dried;
C: the battery separator stripping and slicing by after oven dry:
D: the battery separator after stripping and slicing is entered grinding.
Further, described step a comprises the desulfurization cleaning and de-plumbous cleaning carried out respectively.
Further, described step a comprises the desulfurization cleaning and de-plumbous cleaning carried out simultaneously.
Further, described desulfurization cleaning and de-plumbous cleaning are cleaned in cleaning machine.
Further, the cleaning fluid that described desulfurization cleaning adopts is in energy and the alkaline solution of sulphur, and the cleaning fluid that described de-lead cleaning adopts is to neutralize plumbous alkaline solution.
Further, described desulfurization and de-plumbous employing be the alkaline solution that can neutralize lead and sulphur.
Further, dry in dryer in described step c.
Further, described bake out temperature is at 100 DEG C ~ 200 DEG C.
The recovery method of waste and old lead acid accumulator dividing plate of the present invention is by first cleaning old and useless battery dividing plate, and then dry, carry out stripping and slicing again, finally grind, compare existing processing method, cost is low, and the dividing plate after process can be utilized again, to reach recycling of resource, further reduce costs.
Accompanying drawing explanation
Fig. 1 is the process chart of the better embodiment of the recovery method of waste and old lead acid accumulator dividing plate of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
Embodiment 1
As shown in Figure 1, the better embodiment of the recovery method of waste and old lead acid accumulator dividing plate of the present invention comprises the following steps:
Step a: cleaned in cleaning machine by battery separator, the cleaning fluid that cleaning machine adopts is sodium hydroxide solution, the lead during NaOH can be used for and on battery separator and sulphur, and make it carry out de-plumbous and desulfurization, cleaning efficiency is high simultaneously.Certainly in other embodiments, cleaning fluid can also be mixed type solution, as the mixed solution of NaOH and calcium hydroxide, cost-saved; Certainly also first can add NaOH, repeated hydrogenation calcium oxide, effect is better.
Step b: after having cleaned, battery separator is placed on inside dryer and dries, bake out temperature is set to 100 DEG C.
Step c: after to be dried, battery separator is utilized cutting machine cutting, is cut into bulk.
Steps d: after stripping and slicing is complete, the battery separator of bulk is ground by grinder.
Wherein cleaning machine can adopt the cleaning machine etc. of rolling type, and dryer can adopt the dryer etc. of infrared-type, and cleaning machine, dryer and cutting machine are existing routine techniques, therefore, do not repeat them here.In other embodiments, as long as cleaning fluid is that to neutralize alkaline mixed solution that is plumbous and sulphur all passable.
By old and useless battery dividing plate is first cleaned, it is made to obtain nontoxic battery separator, and then dry, then carry out stripping and slicing, finally grind, ground battery separator can be regenerated again processing and obtain brand-new battery separator, compare existing processing method, cost is low, and the dividing plate after process can be utilized again, form recycling of resource, further reduce costs.
Embodiment 2
The present embodiment is with enforcement 1 difference, and desulfurization and de-lead are carried out by the present embodiment respectively, and bake out temperature is set as 120 DEG C, and remainder is all identical with embodiment 1.Battery separator is first carried out desulfurization in cleaning machine; And then the battery separator after desulfurization process is carried out in cleaning machine de-plumbous.The cleaning fluid that desulfurization adopts is that the cleaning fluid that described de-lead cleaning adopts is can neutralize plumbous alkaline solution in energy and the alkaline solution of sulphur, and desulfurization and the order that takes off lead can be put upside down.In other embodiments, desulfurization and de-lead also can carry out in service sink.
Embodiment 3
The present embodiment is with enforcement 1 difference, and bake out temperature is set as 150 DEG C by the present embodiment, and remainder is all identical with embodiment 1.In other embodiments, bake out temperature also can be 160 DEG C, 180 DEG C and 200 DEG C etc.
These are only embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every equivalent structure utilizing specification of the present invention and accompanying drawing content to do, is directly or indirectly used in the technical field that other are relevant, all in like manner within scope of patent protection of the present invention.
