In modern industrial production, dust pollution is a problem that cannot be ignored. It not only poses a threat to the health of workers but also has a negative impact on the environment. To address this issue, various dust removal devices have emerged, and the dust removal filter cage, as a key component among them, is quietly playing an important role, serving as the invisible guardian of industrial environmental protection.
I. Working Principle of the Dust Removal Filter Cage
The working principle of the dust removal filter cage is based on the basic mechanism of filtration interception. When the dusty gas passes through the dust removal equipment, it first enters the area of the filter bag supported by the dust removal filter cage. The filter bags are usually made of fibrous materials with fine pores, such as polyester fibers and glass fibers. Large particles of dust are directly impacted by inertia and land on the surface of the filter bag, being intercepted by it. While the fine dust particles follow the airflow and penetrate into the interior of the filter bag, they gradually deposit on the surface of the filter bag, forming a layer of initial dust. As the dust accumulates continuously, this initial layer becomes denser and more porous, and its filtration efficiency also increases accordingly, ultimately achieving a dust removal efficiency of up to 99% or more.
During this process, the dust removal filter cage plays a crucial supporting role. It ensures that the filter bags maintain a stable shape under the impact of the airflow and the load of dust, avoiding the collapse or deformation of the filter bags, thereby maintaining the filter area without reduction and maintaining efficient dust removal effects. At the same time, the reasonable design of the dust removal filter cage structure enables the airflow to be evenly distributed on the surface of the filter bags, avoiding excessive local flow velocity that leads to dust accumulation and blockage on the filter bags, further improving the filtration efficiency and the service life of the filter bags.
