AI Technical Summary

Problems solved by technology

The absorption rate of acid mist can reach 79%, but this method cannot completely solve the problem, and there is still excessive acid mist precipitation
Invention patent 201110035373.9 uses a new type of closed internal formation system, but still needs an external acid mist capture device and neutralization treatment device
[0006] The existing patents all focus on the suppression and treatment of the released acid mist, the effect is mediocre, and the investment cost of equipment transformation is high, the energy consumption of power equipment is large, and the power consumption is high, which does not meet the policy requirements of energy saving

Embodiment Construction

[0018] In the laboratory, two starting lead-acid batteries (6-QA-105) of the same specification are used. One of the electrolytes was added with 60ppm mass concentration of acid mist suppressing reagent, and the other was not added with suppressing reagent as a control sample. Connect to a 50A charge and discharge test device (equipment number: D-S-107), fully charge the two batteries, and then charge them with a current of 5.25A for 2 hours, take two pieces of wet wide PH test paper, the specification is 74mm long and 6mm wide , respectively suspended at 2cm above the air outlet. After 30 seconds, observe the two pieces of test paper. The test paper above the battery without inhibitor is covered with red dots, and the pH value drops from 7 to 2. The surface of the sample test paper with reagent added remains unchanged. After continuing to stand still for 2 minutes, observe that the surface of the test paper adding the sample remains unchanged.

Abstract

The invention provides a method for inhibiting emission of harmful gases in the lead acid battery production process. The method is concretely characterized in that an inhibition reagent is added in the production or use process, and the inhibition reagent can be some fluorine-containing organic matters.

Description

technical field [0001] The invention relates to a method for suppressing the discharge of harmful gaseous pollutants, in particular to a method for suppressing the discharge of gaseous pollutants for lead-acid storage batteries. Background technique [0002] Due to its low price, stable performance, and simple manufacturing process, the output of lead-acid batteries has always occupied an absolute advantage in the total output of chemical power sources. However, the harmful aerosol pollution produced by lead-acid batteries during production and use has always been an industry problem. [0003] During the production and use of lead-acid batteries, a large amount of acid gas will be released. When the current passes through the battery plate, the plate continuously generates oxygen and hydrogen. These gases form bubbles on the surface of the electrolyte, and the bubbles become larger and broken. Due to the power push of the broken bubbles, the liquid on the surface of the bubb...
