Description

Technical Field

[0001] The utility model relates to a dust collecting and recycling device, in particular to a material dust collecting and recycling device for a ternary precursor production workshop. Background Art

[0002] During the ternary precursor production process, materials undergo multiple processing steps, including crushing, mixing, and conveying, which easily generates large amounts of micron-sized dust. This dust is then released into the workshop air, impacting the health of workers and posing a safety hazard. To address this issue, existing technologies often utilize centralized dust removal systems. These systems use fans to drive airflow, drawing dust from various workstations into pipelines and transporting it to dust removal equipment for centralized treatment.

[0003] However, traditional structures still have many shortcomings in practical applications. Specifically, common dust removal equipment mostly adopts traditional technologies such as cyclone dust collectors, bag dust collectors or water film dust removal devices. Cyclone dust collectors have good separation efficiency mainly for large particles, but have weak capture ability for fine particles. Although bag dust collectors have high filtration accuracy, they are prone to clogging in high humidity or sticky dust environments, affecting the stability of system operation. Traditional water film dust removal methods have problems such as limited liquid-gas contact area and poor atomization effect, making it difficult to effectively capture ultrafine particles suspended in the airflow. These devices usually rely on a single physical separation mechanism, such as separating larger particles through centrifugal force, intercepting dust with filter materials, or adsorbing particles by spraying to form a water film. Due to their relatively simple structural design, they lack the ability to effectively grade particles of different particle sizes. Therefore, they show obvious limitations when dealing with fine particles at the micron level and below, and generally have defects such as low capture efficiency, high energy consumption, and frequent maintenance.
