What is the harm of the waste lead-acid battery?

　　Author ：Iflowpower – Portable Power Station Supplier

With the gradual improvement of 720,000 tons / annual waste-free battery recovery network system, the sulfate electrolyte produced by the waste lead-acid battery has also increased, and Henan Yuguang Lead Co., Ltd. has 360,000 tons / The annual waste lead-acid battery automatically dismantles the production line, with an annual output of about 20,000 square meters, using a medium and context disposal will produce a large amount of sludge, and the cost is expensive.

Through the test analysis of the waste lead-acid battery electrolyte ingredients, the author is purified, and the phybrid acid electrolyte acid is immersed in the test, the feasibility demonstration of test exploration and process conditions, found a set of effectively treated waste lead-acid batteries Electrolytic solution. The process reduces the comprehensive disposal cost of the exhaust gas electrolyte of the waste lead-acid battery, and has no pollution, protect the environment. Electrolytic solution treatment process studies the use of waste-based lead-acid battery electrolyte ingredients analysis process Design At present, the company produces nano-zinc oxide and sodium sulfate and sodium carbonate, which uses the company's independent research and development.

The nano-zinc oxide particle size produced by the dry furnace kiln equipment is small, high activity, large specific surface area. Through the application of the waste lead-acid battery electrolytic solution, the author can be compared to the application of the nano-zinc oxide production process of Yuko gold, and the addition of the addition of sulfuric acid electrolytes is caused by the leaching of subtracted zinc. Impact and electrolyte impurities have no effect on product quality.

The laboratory process test laboratory test process is a nano-zinc oxide production process process, and the final product is a wet alkali-zinc carbonate. The specific conditions are the same as the actual production process. The raw material is 200 g of the secondary zinc oxide output from the lead system.

During the acid immersion process, the liquid solid ratio is 5: 1, which except for the desired amount of concentrated sulfur, the remaining liquid is all of the waste lead-acid battery to stand inducee. Educate Electrolyte. Once, the secondary purification has less potassium titratation and zinc powder, no specific weighing.

Specific experiments are shown in Table 2, Table 3, Table 4. As can be seen from Table 2, Table 3, it is the most obvious of the acid immersion in the use of waste lead-acid battery sulfuric acid electrolyte, and the acid immersion is more obvious. The potassium used is slightlymented with potassium and the amount of purge slag is highly verified, and the electrolytic solution is high.

As can be seen from the test results of Table 4, the basic calciocarbonate produced by the waste lead-acid battery sulfuric acid electrolyte is basically in line with the production process requirements. According to the actual situation, according to the actual situation, the waste lead-acid battery sulfuric acid electrolyte 20 is disposed, and the amount of acid is immersed, and the amount of potassium permanganate has been added to 3 times. Next, industrial test, verify this stage test results.

Industrial Test and Production of Henan Yuguangjin Lead Co., Ltd. Renewable Lead Factory and Shaanxi Jinyin Technology Development Co.

, Ltd. uses the automatic surface anti-washing filter to perform multiple live tests, find filtration of electrolyte filtration and The filtration process, October regenerated lead plant replaced the filter film tube to a suitable 80mm diameter PP filter membrane with an idle Gall membrane filter to achieve high efficiency purification treatment of the waste lead-acid battery electrolyte, which is a secondary zinc oxide production of nanometers. Zinc oxide supplies pure sulfuric acid electrolyte.

At 8:30 on October 11, 2016, the author used acid immersed 2 kettle in the zinc oxide plant. The electrolytic solution of the sulfuric acid electrolytic solution was pulphed by about 4 m3 after purification, and the sulfuric acid was leached. 3.

5M3 acid immersion liquid, potassium polymented potassium permeate for a purification. The amount of the original excipient for the acid immersion process is shown in Table 5. It can be seen from the treatment of the original excipients from the 5 acid immersion process.

Since the acidic acid electrolytic acid electrolytic acid electrolytic acid electrolytic acid induction is low, the amount of sulfuric acid in the production is not large, the acid immersion final acid is substantially the same. The amount of potassium permanganate used in a net process is added to normal production, and if calculated according to the amount of liquid, the amount of potassium permanganate is increased by 0.218kg / m3 to 0.

68kg / m3, and converted into 0.218kg / m3. Zinc oxide unit consumption is: 0.

63×0.68 / 0.218 = 1.

98kg / t. After testing, the final product nano-zinc oxide indicator is qualified.
