Below in conjunction with the drawings and specific embodiments the present invention is done explanation in further detail.
The structural representation that becomes workshop acid solution recovery system by Fig. 1～lead-acid battery electrode plate transplantation shown in Figure 3 as can be known, it comprises a plurality of sour device and one group of acid storage tank 1 taken out, every row electrolytic bath 2 all is connected with one and takes out sour device, each is taken out sour device and is communicated with acid storage tank 1; Described acid storage tank 1 is communicated with complex acid equipment.
Describedly take out sour device and comprise that vacuum takes out sour machine 4, acid extracting pipe 3, acid extracting pipe valve 5 and support 7, an end and the vacuum of described acid extracting pipe 3 taken out sour machine 4 and is communicated with, and the other end connects acid extracting pipe valve 5 and can stretch in the electrolytic bath 2.The mid portion of acid extracting pipe 3 is slidingly fitted on the support 7 by a plurality of movable hoisting rings 6.In the present embodiment, described support 7 is a steel wire cable.
Described vacuum is taken out sour machine 4 and is comprised vacuum tank 43, vacuum pump 45 and take out sour pump 41, and have three interfaces on the described vacuum tank 43, one of them interface is communicated with vacuum pump 45, and second interface is communicated with acid extracting pipe 3, and the 3rd interface is communicated with acid storage tank 1.Also be provided with filter 42 between described the 3rd interface and the acid storage tank 1.Has the bracing frame 44 of reinforcement in the described vacuum tank 43.First interface of described vacuum tank 43 and second interface all be positioned at vacuum tank 43 above, the 3rd interface is positioned at the bottom of vacuum tank 43.
Installation process of the present invention is as follows:
1) near the end of every row electrolytic bath 2 vacuum is installed and takes out sour machine 4, wherein the volume of vacuum tank 43 is about 1000 liters, makes with acidproof PVC plastics;
2) draw an acid extracting pipe 3 from vacuum tank 43 tops, tubing is acidproof plastic flexible pipe, internal diameter is 25mm～30mm, about 2 meters height draws a steel wire cable to make support 7 directly over electrolytic bath 2, the steel wire cable oil lubrication, acid extracting pipe 3 is suspended under the steel wire cable, and every interval 0.6m～0.8m buckles a movable hoisting ring 6, and acid extracting pipe 3 can freely be slided by the end to end from electrolytic bath 2 on steel wire cable back and forth; The end of acid extracting pipe 3 connects an acid extracting pipe valve 5, and this acid extracting pipe valve 5 plays the effect of a valve that is communicated with or cuts out, the end of acid extracting pipe 3 can test to the bottom of electrolytic bath 2; The acid solution that changes in the electrolytic bath 2 is taken out sour machine 4 by this root acid extracting pipe 3 by vacuum exactly and is taken away;
3) in vacuum tank 43 bottoms that vacuum is taken out sour machine 4 valve is installed, valve connects a filter 42 outward again, filter 42 is the square box of PVC plastic production, size is about 30cm * 20cm * 20cm, inside is put some acidproof screen packs and is filtered the scum silica frost that may exist in the acid solution, the top of casing can be dismantled with convenient and regularly be cleaned, and uses rubber ring seal; Connect one again outside the filter 42 and take out sour pump 41, acid solution is extracted into one group of acid storage tank of concentrating 1 stores;
4) all centralized collection is in one group of acid storage tank 1 for all acid solutions, and the tank body volume is 10 cubic metres, and one has four acid storage tanks, and acid storage tank 1 is connected with the complex acid equipment in complex acid workshop, makes the acid solution recycling that can circulate.
Operating process of the present invention is as follows:
When electrolytic bath 2 need be taken out acid, start vacuum pump 45, notice that sour pump 41 is taken out in inspection and acid extracting pipe valve 5 all is in closed condition this moment, after vacuum degree reaches certain requirement, open 5 beginnings of acid extracting pipe valve and take out acid at electrolytic bath 2 one by one, acid extracting pipe 3 can be free to slide to the top that each changes into sulculus by movable hoisting ring 6, after exhausting last and changing into sulculus, after treating that acid extracting pipe 3 interior acid solutions all flow into vacuum tank 43, keep the acid extracting pipe valve 5 of acid extracting pipe 3 to be in open mode, close the vacuum pump 45 of taking out sour machine, make vacuum tank 43 return to atmospheric pressure state; Startup is taken out sour pump 41 acid solutions in the vacuum tank 43 is extracted in the acid storage tank 1, exhausts the back and shuts down, and closes the valve of taking out sour pump 41 and gets final product; Acid storage tank 1 is connected with complex acid equipment, the acid solution of collecting is used to prepare the sulfuric acid liquid of various density.
The recycled scheme of acid solution that the present invention collects is as follows:
1) to be used to prepare density be that changing into of 1.03g/cm3～1.08g/cm3 used sulfuric acid liquid to an acid solution part of Shou Jiing.Electrolytic bath must be cleared up once usually in per 3 months, and the acid solution in the groove is all taken away, and the mud in the groove is cleaned out, and bus also will more renew in case of necessity.Calculate by changing into 36 row pole plates every day, every month 25 days working day, need clean 0.48 row electrolytic bath average every day, needs to add again new sulfuric acid liquid after the cleaning, and every sulculus is about 60 liters, 6000 liters of every row, calculate with this,, need 2880 liters average every day, and every day, recovery total was 18000 liters, and this part recovery accounts for 16% of total amount.
2) an acid solution part of Shou Jiing is used to prepare the coated plate pouring acid sulfuric acid liquid that density is 1.06g/cm3～1.15g/cm3.Calculate by producing 50 tons of pole plates every day, every day, coated plate needed to consume 32 tons of lead powder approximately, and about 35 tons of lead plasters need to consume about 3200 liters and drench acid solution.These drench acid solution can prepare with the sulfuric acid liquid of collecting that changes into, and adds an amount of concentrated sulfuric acid and gets final product.This part recovery accounts for 17.8% of total amount.
3) a sulfuric acid part of Shou Jiing be used to prepare density be 1.40g/cm3 with cream sulfuric acid liquid.As long as the strict control of pole plate production process contaminating impurity, the acid solution impurity level that changes into collection can reach and the cream requirement fully, can be used to prepare the sulfuric acid liquid of using with cream.Calculate by producing 50 tons of pole plates every day, every day and cream need to consume 32 tons of lead powder approximately, and the sulfuric acid liquid that it is 1.40g/cm3 that lead powder per ton on average needs 90 kilograms of density approximately need consume about 1548 liters of recovery acid solutions every day and prepare.This part recovery accounts for 8.6% of total amount.
4) a sulfuric acid part of Shou Jiing is used to prepare the battery sulfuric acid liquid that density is 1.32g/cm3.As long as the strict control of pole plate production process contaminating impurity, the acid solution impurity level that changes into collection can reach the requirement of battery with sulfuric acid liquid fully, can be used to prepare the sulfuric acid liquid that battery is used.Calculate by producing 50 tons of pole plates every day, can produce the battery of about 37800 12V7Ah, need about 14700 liters of battery acid liquid, need to consume about 12000 liters of acid solutions that change into collection.This part recovery accounts for 66.7% of total amount.
Through above calculating as can be known, changing into the recovery acid solution can all circulate.
In addition, when preparation and cream usefulness sulfuric acid liquid and battery usefulness sulfuric acid liquid, can suitably add recovered acid less, replenish some pure water and can solve the impurity problem.
