Environmental-protection treatment system for production process of lead-acid battery polar plate

Abstract

The invention discloses an environmental-protection treatment system for a production process of a lead-acid battery polar plate, which comprises a lead dust, lead fume and lead steam collecting treatment system and an acid mist and waste acid collecting treatment system. In the two systems, lead pollutants and acid pollutants are subjected to suction type collection by adopting a negative pressure system to prevent the pollutants from being discharged inadequately at the operating station effectively; and atomizing treatment is adopted in the two systems, an integral atomizing treatment system is filled with water mist, when passing through the water mist, the lead pollutants or the acid pollutants are adsorbed to subside under the action of gravity, and all sewage is conveyed to a wastewater treatment system for regenerating, so that collected lead powder can be put on production again, and purified water can be formed and can be used in the production process of lead-acid batteries circularly. Therefore, the environmental-protection treatment system can collect and purify the pollutants effectively to achieve the effect of cyclic utilization and realize zero release for environment basically.

Description

technical field [0001] The invention relates to an environment-friendly treatment system for the production process of lead-acid battery polar plates. Background technique [0002] The production of lead-acid batteries is mainly divided into two parts, one is to produce plates, and the other is to assemble and form batteries. Since the raw material of the lead-acid battery plate is lead, a large amount of lead fume, lead powder and lead vapor will be generated during the production process, and if it is directly discharged into the environment, it will cause serious pollution. Therefore, the country has strict environmental protection requirements for the production of lead plates. In addition, the formation solution or electrolyte in the formation process of the lead-acid battery is easy to form acid mist and acid waste water. If it is directly discharged, it will also have a certain impact on the environment. In summary, in the production process of lead-acid batteries R...

AI Technical Summary

Problems solved by technology

In addition, the formation solution or electrolyte in the formation process of the lead-acid battery is easy to form acid mist and acid waste water. If it is directly discharged, it will also have a certain impact on the environment. In summary, in the production process of lead-acid batteries Reasonable environmental protection measures must be taken to solve the problem of environmental pollution

The current production of lead-acid batteries has not done enough in terms of environmental protection measures. The treatment process for lead pollution is complex and inefficient. The acid mist and acid waste water are discharged after simple neutralization, which still pollutes the environment.
