Sintered Mesh Filter Discs

Sintered Stainless Steel Filter Disc Manufacturer

Sintered mesh filter is a high-performance industrial metal filter element. It is a rigid, integral, porous filter material made of multiple layers of metal wire mesh (usually stainless steel wire mesh, but also other metals such as nickel and titanium) with different mesh sizes (aperture sizes), through a special laminated design, pressed under high temperature and high pressure, and then sintered in vacuum or protective atmosphere.

Multi-layer composite structure of sintered mesh filter (usually five layers):

Protective layer (outermost layer): A coarser wire mesh that provides mechanical protection to prevent the filter layer from being damaged by the impact of large particles.

Control layer (second layer): medium precision wire mesh, which guides the fluid and assists in supporting the filter layer.

Filter layer (core layer): The finest mesh, responsible for achieving precise filtration accuracy (ranging from 1 micron to several hundred microns).

Control layer (fourth layer): Same as the second layer, symmetrical structure to ensure strength.

Support layer (innermost layer): A thicker wire mesh that provides strong mechanical support, withstands pressure differences, and prevents the filter layer from deforming and rupturing.

Sintered mesh filters have excellent mechanical strength and rigidity:

The high temperature sintering process fuses each layer of wire mesh at the contact points to form a strong overall structure.

It has strong resistance to pressure, impact and bending deformation, and can work stably under high pressure difference and mechanical vibration environment.

It can be processed into various shapes (round, square, rectangular, cylindrical, conical, special-shaped parts, etc.) without being easily deformed.

Sintered mesh filters have high precision and high uniformity:

The pore size of the filter layer is uniform and stable, which can achieve precise particle retention and high filtration efficiency.

The combination of surface filtration and deep filtration provides a large dirt holding capacity.

Sintered mesh filter has excellent temperature resistance and corrosion resistance:

The main materials (such as 304, 316L stainless steel) have excellent high temperature resistance (up to 800°C or more, depending on the material) and corrosion resistance, and are suitable for harsh chemical and high temperature environments.

Sintered mesh filter has good backwashing and regeneration performance:

The rigid structure enables it to withstand a variety of cleaning methods such as high-pressure backwashing, ultrasonic cleaning, baking, pickling, etc.

After cleaning, the performance is restored well, the service life is long, it can be reused, and the operating cost is reduced.

Sintered mesh filter has high porosity and low fluid resistance:

The opening rate is high, the fluid passes smoothly, and the initial pressure drop is low.

Sintered mesh filter has no material falling off:

The metal material itself is not easy to shed fibers or particles, and does not pollute the downstream process. It is suitable for occasions with high cleanliness requirements (such as food, medicine, and electronics).

The main application areas of sintered mesh filters :

Sintered mesh filter discs are widely used in industrial fields with high requirements on filtration accuracy, strength, temperature resistance, corrosion resistance and service life due to their excellent performance:

Ø Petrochemical industry: Catalyst recovery, crude oil, solvent and gas filtration in oil refining, chemical fiber and ethylene production.

Ø Chemical industry: Filtration of strong acids, strong alkalis, organic solvents, and high-temperature molten polymers.

Ø Pharmaceuticals and bioengineering: Precision sterilization and filtration of drug solutions, solvents, water for injection, and sterile air.

Ø Food and Beverage: Filtration of edible oil, alcohol, syrup, juice, milk, purified water and compressed air.

Ø Water treatment: seawater desalination pretreatment, ultrafiltration/reverse osmosis security filtration, wastewater treatment.

Ø Mechanical and hydraulic: high-pressure, high-precision filtration of hydraulic oil, lubricating oil, and fuel systems.

Ø Gas purification: oil, water and dust removal of compressed air, industrial gas and inert gas.

Ø High temperature flue gas treatment: High temperature gas dust removal.

Ø Powder Metallurgy: Metal powder filtration.

Typical application of sintered filter discs in vulcanization reaction plates

1. Integral distribution plate

Large sintered metal circular plates/rectangular plates (thickness 10~50mm) are directly used as air distribution plates and welded to the bottom of the reactor.

Advantages: No seams, zero risk of leakage

2. Modular filter array

Hundreds of small sintered filter discs (such as 100×100mm) are embedded in a pressure-resistant frame to form a distributed air distribution system.

Advantages: Partial damage can be replaced separately, low maintenance cost

3. Sintered filter + support grid composite structure

The sintered filter disc is laid on the perforated plate support frame, which is suitable for reactors with extra-large diameters.

Typical case: The gas distribution plate of zinc concentrate fluidized roasting furnace generally adopts 316L sintered filter (pore size 40μm), which has a service life of more than 5 years.

Sintered mesh filter is a high-performance, high-precision, long-life, deep-cleaned and regenerated metal filter element that fuses multiple layers of metal wire mesh into a solid whole through a high-temperature sintering process. Its multi-layer composite structure design is the core of its high performance, making it an irreplaceable advantage in complex industrial filtration scenarios with high temperature, high pressure, strong corrosion and high cleanliness requirements. Dashang Wire Mesh can provide various types of filter materials and has strong design and processing capabilities. It can be customized according to customer drawings or needs.
