Sintered metal fiber felt operates on similar principles to other filter media. However, its unique properties, such as high porosity, significantly enhance permeability compared to other types of media. This media is commonly employed for filtering gases or liquids.
Sintered metal fibers create a porous and intricate path that obstructs and retains particles as the fluid being processed passes through the depth filter. Over time, trapped particles accumulate on the surface of the media, forming filter cake deposits. Additionally, more particles adhere to the previously retained ones. During dust removal, particularly in heavily polluted gas streams, the particles rapidly form a filter cake on the media surface, leading to an increased pressure drop. As more particles accumulate on the surface, the pressure drop continues to rise until the filter reaches its maximum pressure drop limit.
In self-cleaning filters, the cleaning process commences, and clean gas or liquid is released in a countercurrent manner to eliminate the filter cake.
Titanium fiber felt
Nickel fiber feltAs particles traverse porous materials, they collide and adhere to fibers through four primary mechanisms. Toptitech supplies titanium fiber sintered felt, which comprises metal fibers with a micron-scale diameter. These fibers are arranged through non-woven laying, lamination, and high-temperature sintering. The multi-layered metal felt possesses a gradient of pore sizes across its layers, allowing for precise filtration accuracy and greater dirt-holding capacity compared to single-layer felt.
The titanium fiber sintered felt maintains a continuous filtering effect and exhibits characteristics of a three-dimensional network, porous structure, high porosity, large surface area, and uniform pore size distribution. It also demonstrates excellent structural properties.
Consequently, titanium fiber sintered felt effectively overcomes the drawbacks of easily clogged and damaged metal mesh. It compensates for the fragility and low flow rate of powder filtration products and resolves the temperature and pressure resistance limitations of filter paper and cloth. Hence, stainless steel sintered felt exhibits exceptional filtration performance, making it ideal for applications requiring high-temperature resistance, corrosion resistance, and high-precision filtration.
