Cómo controlar la generación de polvo en el reciclaje de baterías de litio

During lithium battery recycling, dust generation can be effectively reduced by installing dust covers on screw conveyors and rotary screeners. These covers, made from metal or durable materials, enclose the material pathway, trapping dust near its source and minimizing material loss. Additionally, a negative pressure collection system captures dust at transfer points, safely storing it while preventing escape into the environment. This combination of dust covers and vacuum collection ensures cleaner operations and reduces waste during the recycling process.

During lithium battery discharging and drying, harmful dust and odors are produced. To remove them effectively, exhaust air first passes through a spray tower, which captures dust and soluble gases with water droplets. Next, an activated carbon adsorption box traps volatile organic compounds and odors. Finalmente, a UV photolysis unit breaks down remaining harmful molecules using ultraviolet light. This integrated system ensures efficient removal of dust and odors, protecting both the environment and workers’ health while maintaining safe operations.

According to industry regulations, permissible dust concentrations in workplaces are usually below 10 mg/m³ for total dust and 3 mg/m³ for respirable dust. By installing pulse and cyclone dust collectors, you can reduce dust emissions by over 95%. When you add spray towers, activated carbon, and UV photolysis units, you further cut down residual dust and odors. These combined systems make it possible for your facility to easily exceed international dust suppression standards, ensuring compliance and safe working conditions.
