An acid mist absorption device for lead-acid batteries

Abstract

The invention discloses an acid mist absorption apparatus used for a lead-acid storage battery. The acid mist absorption apparatus comprises an upper cover and a hollow shell with an opening in the upper end, wherein the upper cover and the shell are matched in use; an exhaust port is formed in the top end of the upper cover; an air inlet pipe which extends to the shell is arranged in the centre of the bottom end of the shell; a liquid accumulation pool is arranged at the bottom of an inner cavity of the shell; block alkali is placed at the bottom of the liquid accumulation pool; an air escaping plate and a reaction layer positioned above the air inlet pipe are also arranged in the inner cavity of the shell in sequence; an annular air guiding part for accommodating the air inlet pipe is arranged at the bottom end of the air escaping plate; air escaping holes are formed in the corresponding positions of the air escaping plate; when the acid gas in the lead-acid storage battery passes through the acid mist absorption apparatus disclosed in the invention, the acid gas is in contact with the large-surface porous alkali material in the absorption apparatus, and sulfuric acid in the acidgas and the alkali material are subjected to an acid and alkali neutralization reaction to be absorbed, so that the sulfuric acid mist content in the gas is greatly lowered, air in a storage batterycabin is purified, and the cabin environment is improved.

Description

technical field [0001] The invention belongs to the technical field of acid mist absorption devices, in particular to an acid mist absorption device for lead-acid storage batteries. Background technique [0002] Lead-acid battery is a kind of chemical energy storage device, which is widely used in the fields of automobiles, locomotives, tanks, power stations, ships and underwater vehicles because of its long life, stable performance, safety and reliability, and low price. Since the flooded lead-acid battery can be made into a super large capacity, it is used in underwater vehicles to provide lasting power for the navigation of the vehicle. [0003] However, the use of flooded lead-acid batteries in confined spaces also has disadvantages: a large amount of acid mist generated by the battery is discharged into the battery cabin, which not only corrodes the metal products and equipment in the cabin, but also adheres to the battery. The surface of the battery will cause a sharp...

Problems solved by technology

[0003] However, the use of flooded lead-acid batteries in confined spaces also has disadvantages: a large amount of acid mist generated by the battery is discharged into the battery cabin, which not only corrodes the metal products and equipment in the cabin, but also adheres to the battery. The surface of the battery pack will cause a sharp drop in the insulation resistance of the battery pack to the ground, and a significant increase in the leakage current, which will cause harm to the safety of equipment and personnel.
