Acid recovery system for lead-acid battery plate formation workshop

Abstract

The invention discloses an acid recovery system for a lead-acid storage battery polar plate formation workshop, which comprises a plurality of acid pumping devices and a group of acid storage tanks (1), each row of forming tanks (2) is connected with an acid pumping device, Each acid pumping device is communicated with the acid storage tank (1); the acid storage tank (1) is communicated with the acid distribution equipment. After adopting the above structure, using the principle of vacuum acid pumping, each row of chemical formation tanks pumps the acid solution into the acid storage tank through the acid pumping device for storage, and when it is stored to a certain amount, it is pumped into the acid distribution equipment for recycling. It can recycle the flowing sulfuric acid, save production cost, avoid environmental pollution, save energy and protect the environment.

Description

technical field [0001] The invention relates to the field of accumulators, in particular to an acid recovery system for a lead-acid accumulator polar plate forming workshop. Background technique [0002] Lead-acid batteries are widely used in various fields due to their easy availability of raw materials, low price and sufficient reliability in use. Lead-acid batteries are small in size, so the size of their plates is also small, usually multi-piece design, this large piece of multi-piece is called a grid, and then the grid is coated with lead paste. . In the normal plate production process, there is usually a process of formation, which refers to the process of using chemical and electrochemical reactions to convert the plate into positive and negative plates with electrochemical characteristics, that is, for new production The process of charging the battery for the first time. The density of the electrolyte used for plate formation is usually sulfuric acid solution of ...

Problems solved by technology

These sulfuric acid liquids are usually pumped out of the chemical tank and directly discharged to the ground, and flow into the wastewater treatment tank through the drainage ditch, which not only wastes the sulfuric acid, but also consumes a large amount of alkaline chemicals such as caustic soda and lime to neutralize it. Sulfuric acid is acidic, and it is easy to corrode the floor of the workshop, which brings great pressure to environmental protection.
