Waste lead-acid storage battery disassembling waste acid treatment system

Abstract

The invention belongs to the technical field of waste acid treatment, and particularly relates to a waste lead-acid storage battery disassembling waste acid treatment system. The system at least comprises a stock solution tank, a plate-frame filter press, a filtrate tank, a front plate type heat exchanger, a multi-medium filter, a micro-filtration membrane system, a micro-filtration liquid tank, amiddle plate type heat exchanger, a ceramic membrane system, a ceramic membrane collecting tank, a rear plate type heat exchanger, a front security filter, a tail nanofiltration membrane system and arecycled acid tank which communicate with one another in sequence. By means of the waste lead-acid storage battery disassembling waste acid treatment system, waste lead-acid storage battery disassembling waste acids can be effectively treated.

Description

technical field [0001] The invention belongs to the technical field of waste acid treatment, and in particular relates to a waste acid treatment system for dismantling waste lead-acid batteries. Background technique [0002] Lead-acid battery is the battery with the largest output and widest application among all kinds of batteries in the world. It has the advantages of reversibility, stable voltage characteristics, large discharge capacity, and low cost. It is used in various fields of national economy. With the development of economy and society, the consumption of lead-acid batteries is increasing, and more and more lead-acid batteries are scrapped and updated. If not handled properly, waste lead-acid batteries will cause serious pollution to the environment. If it is properly recycled, lead and other raw materials can be recovered, reducing the consumption of primary battery materials and protecting limited mineral resources, which can promote the sustainable developmen...
