In today's era of growing environmental awareness, the environmentally friendly recycling of waste batteries has become a focus of attention. Improper handling of heavy metals and chemicals contained in waste batteries will cause serious pollution to soil, water sources, etc. In the process of waste battery recycling, pulse dust collectors are playing an indispensable and important role.

As an efficient dust removal equipment, the working principle of the pulse dust collector is based on the filtration of dust-containing gas by filter bags. When waste batteries undergo preliminary treatments such as shredding and crushing, a large amount of fine dust will be generated. These dusts are sent into the pulse dust collector through the induced draft fan along with the air flow. After the dust-containing gas enters the dust collector, the dust particles are intercepted by the filter bag, and the clean gas enters the clean air chamber through the filter bag, and is finally discharged by the induced draft fan. With the continuous accumulation of dust on the surface of the filter bag, the pulse valve will open according to the set cycle, and compressed air is instantly injected into the filter bag, causing the filter bag to expand rapidly and produce strong vibration, shaking off the attached dust into the ash hopper, so as to realize the effective collection of dust.

In the field of environmental protection recycling of waste batteries, pulse dust collectors have shown many significant advantages. Its dust removal efficiency is extremely high, and its ability to capture fine dust is strong, usually reaching more than 99%, which ensures that the air quality in the recycling workshop meets strict environmental protection standards, greatly protects the health of workers, and avoids pollution to the surrounding environment caused by dust emissions. For example, after a large waste battery recycling enterprise introduced pulse dust collectors, the dust concentration in the workshop was significantly reduced, and health problems of workers caused by dust pollution were obviously reduced.

Pulse dust collectors also have good adaptability. It can be custom - designed according to the specific process of waste battery recycling and dust characteristics. In the recycling of waste lithium - ion batteries, because the dust may have characteristics such as high temperature, high humidity, flammability, explosiveness or corrosiveness, pulse dust collectors can meet the dust removal needs under complex working conditions by selecting filter bags of different materials, such as polyester fiber, polyacrylonitrile, polytetrafluoroethylene, etc. A factory dealing with waste lithium - ion batteries has dust with certain corrosiveness. By using pulse dust collectors with polytetrafluoroethylene filter bags, efficient dust removal is stably realized, and no faults caused by dust corrosion have occurred in the equipment after years of operation.

In addition, the pulse dust collector operates stably and reliably. It has a compact structure and a high degree of automation. By reasonably setting the pulse injection cycle and parameters, it can operate stably for a long time with a low failure rate. The equipment has low resistance and moderate wind speed, which further ensures long - term stable operation. Moreover, its maintenance is relatively simple, and operations such as filter bag replacement and ash cleaning device maintenance are easy to implement. Regularly checking the wear of the filter bag, the tightness of the upper and lower ports, and the operation status of components such as the ash cleaning system and the fan can ensure the good overall performance of the equipment.

At present, pulse dust collectors have been widely used in many waste battery environmental protection recycling projects and achieved remarkable results. In some waste lead - acid battery recycling factories, pulse dust collectors have effectively controlled the emission of lead dust and reduced the harm of lead pollution to the environment and human body. In the field of waste lithium - ion battery recycling, it has also become one of the key equipment to ensure a clean production environment and realize efficient resource recycling. With the continuous improvement of environmental protection requirements and the continuous development of the waste battery recycling industry, pulse dust collectors will play a more important role in it, helping the waste battery recycling industry move towards a more green, environmental protection and efficient direction.
