Abstract

The invention relates to the field of lead-acid batteries, in particular to an acid circulation formation acid mist removing device and method of a lead-acid battery. The acid circulation formation acid mist removing device comprises an acid storage tank and a storage battery, wherein the acid storage tank is connected with an air inlet pipeline through an acid returning pipeline; a liquid injection hole of the storage battery is connected with a battery connector; the acid inlet of the battery connector is connected with an acid inlet pipeline; the acid outlet of the battery connector is connected with the acid returning pipeline; the acid returning pipeline is connected with an acid mist removing pipeline; the acid mist removing pipeline is connected with an acid mist removing device; the acid mist removing device is connected with an exhaust pipeline through a fan. By adopting the acid circulation formation acid mist removing device, a gas generated in formation can be centrally collected and treated, the acid mist can be treated by using a physical method and can be subjected to up-to-standard release, the structure is simple, the gas is convenient to collect and treat, and the operation cost is lowered.

Description

technical field [0001] The invention relates to the field of lead storage batteries, in particular to a device and method for acid cycle formation of lead storage batteries to remove acid mist. Background technique [0002] At present, one of the main stages in the production process of lead-acid batteries is the "formation" stage. This stage is mainly to form the plates. The components are lead dioxide and metallic lead. Due to the principle of electrochemical reaction, a large amount of gas (hydrogen and oxygen) will be generated in this process. The rising gas will carry some acid droplets away from the battery, forming the so-called "acid mist". Because acid mist will not only cause human injury, but also pollute the environment, acid mist treatment is required before discharge. The traditional chemical formation and acid mist removal method is: the battery is placed in a water bath for battery formation, the upper part of the water bath is equipped with a cover, and an...
