Filter screen 14, pickle runner 15 and dilute sulfuric acid pond 16 form.
Background technology：
The principle equation of lead-acid accumulator charge and discharge chemical reaction is as follows：
Charging reaction：PbO2+2H28O4+ Pb+2e==2PbSO4+2H2O
Exoelectrical reaction positive pole：PbO2+2e+SO4 2-+ 4H+==PbSO4+2H2O
Negative pole：Pb-2e+SO4 2-==PbSO4
Contain in lead-acid accumulator waste sulfuric acid：85% water, 10% H2SO4With PbSO4And a small amount of dust, PbO2
And Fe ions, discarded sour water generally use membrane separation process Recycling of waste liquid is given up at present, the primary recovery about 75% of sulfuric acid,
Iron concentration exists in sulfuric acid, below 0.8ppm, can meet the quality requirement of pole plate production；But the solid content to filtering out is not yet
Utilize, and removal process is discontinuous, low production efficiency.
Utility model content：
More effectively also to reclaim the available thing in lead-acid accumulator waste liquid, the recycle and reuse system of lead-acid accumulator waste liquid
System should be by waste liquid pool 1, acid-proof pump 2, sour pump discharge valve 3, flushing valve 4, backwash device outlet 5, collection layer filter inlet 6, collection layer mistake
Filter 7, collection layer filter membrane 8, differential manometer 9, collection layer filter outlet 10, dilute sulfuric acid valve 11, backwashing pump outlet valve 12, backwash
Pump 13, screen pack 14, pickle runner 15 and dilute sulfuric acid pond 16 form.Aspirated in the entrance insertion waste liquid pool 1 of acid-proof pump 2 useless
Acid solution；The outlet of acid-proof pump 2 consolidates with the entrance UNICOM of sour pump discharge valve 3, outlet and the collection layer filter of sour pump discharge valve 3
The UNICOM of entrance 6 is the same as knot.Collection layer filter membrane 8 is placed in the Inner of collection layer filter 7 and is classified as two sections of entrance and outlet.Collection layer filter goes out
The entrance UNICOM of mouth 10 and dilute sulfuric acid valve 11 consolidates, outlet and the UNICOM of dilute sulfuric acid pond 16 of dilute sulfuric acid valve 11.Backwashing pump 13
In the acid solution in entrance insertion dilute sulfuric acid pond 16, the outlet of backwashing pump 13 consolidates with the entrance UNICOM of backwashing pump outlet valve 12,
The outlet of backwashing pump outlet valve 12 and the UNICOM of collection layer filter outlet 10, can rush the solid content for collecting the entrance side of layer filter membrane 8
Dilute sulfuric acid pond 16 is flowed back to flushing valve 4 and along pickle runner 15.Available solid content PbSO in counter-flushing liquid4Deng being filtered
Net 14 is sent to after filtering out melts lead stove smelting.The collection layer filter membrane 8 of lead-acid accumulator Mead-Bauer recovery system is by two to ten layers of filter membrane weight
Folded to form, first layer is the mesh stainless steel system filter screen of 80 mesh 1；It is stainless that the top of pickle runner 15 is covered with the mesh of 80 mesh one -200
Steel system filter screen, whole runner tilt 15 ° -60 °.One of differential manometer 9 in the recycle and reuse system of lead-acid accumulator waste liquid
End and collection layer filter 7
The arrival end of middle collection layer filter membrane 8 communicates, and the other end communicates with collecting the port of export of layer filter membrane 8.
Brief description of the drawings：
Fig. 1 are the recycle and reuse system diagrams of lead-acid accumulator waste liquid,
Wherein：1-- waste liquid pools, 2-- acid-proof pumps, 3-- acid pump discharges valve, 4-- flushing valves, the outlet of 5-- backwashes device, 6-- collection
Layer filter inlet, 7-- collection layers filter, 8-- collection layers filter membrane, 9-- differential manometers, 10-- collection layers filter outlet, 11-- are dilute
Sulfuric acid valve, 12-- backwashing pumps outlet valve, 13-- backwashing pumps, 14-- screen packs, 15-- pickles runner, 16-- dilute sulfuric acids
Pond.
Embodiment：
Fig. 1 is also the recycle and reuse system diagram for handling the lead-acid accumulator waste liquid of 2.5 ten thousand tons of spent acid amount in year.Contribute
5m3The entrance insertion volume 500m of/h, Yang journeys 150m acid-proof pump 23Waste liquid pool 1 waste liquid in, its export highly pressurised liquid warp
Sour pump discharge valve 3 enters in collection layer filter 7.Under the driving of pressure, acid accumulator penetration is crossed after collection layer filter membrane 8 through collecting layer filtering
Device outlet 10, dilute sulfuric acid valve 11 flow into volume 500m3Dilute sulfuric acid pond 16 in store.And cut on the collection entrance side of layer filter membrane 8
The solid content left is accumulated on the left side filter screen of collection layer filter membrane 8, stockpiles that thing is more, and the pressure difference that differential manometer 9 indicates is bigger, works as pressure
When difference exceedes setting value, controller, which is just commanded, closes acid-proof pump 2, sour pump discharge valve 3 and dilute sulfuric acid valve 11, opens backwash and pumps out
Mouth valve 12, backwashing pump 13 and flushing valve 4, pickle reversely flow through backwashing pump 13, backwashing pump outlet from dilute sulfuric acid pond 16
Valve 12 and flushing valve 4 enter pickle runner 15.Diluted acid flows into dilute sulfuric acid pond 16 through screen pack 14 on pickle runner 15
In, the solid content that is retained down on screen pack 14 is sent to by conveyer belt to be melted lead stove and goes to recycle.Collect the solid on layer filter membrane 8
Thing is backwashed wash out after, the pressure difference that differential manometer 9 indicates is reduced by, small to after setting value, the recovery of lead-acid accumulator waste liquid with again
Just recover normal work using system.
