The difference between sintered plate filter media and bag filter media:

The external shape of the plastic sintered plate is characterized by a wavy design reminiscent of an accordion box. If expanded into a flat surface, it equates to a threefold increase in surface area. The internal structure of the wavy filter plate is divided into 17 cavities. This design, in addition to considering the strength of the components, is primarily driven by aerodynamic requirements to ensure efficiency during pulse jet backwashing for dust removal. The dust collector assembled with this material occupies only 1/2 to 1/3 of the space required by a bag-type dust collector with the same filtering area. The overall structure is also reduced accordingly, featuring space-saving characteristics that facilitate user factory design and reduce the total cost of equipment.

Thermosetting plate model:

The common temperature resistance of sintered plates is: 70℃ (room temperature)

Special Performance Sintered Plates: Acid-resistant, anti-static, explosion-proof, oil and gas-resistant, etc.

Under normal circumstances, the dust concentration at the inlet can reach 500g/m³, while the dust concentration in the exhaust can be controlled below 5mg/m³. In high-concentration dust removal systems, the dust removal efficiency reaches 99.99%. Widely used in industries such as rolling steel, metallurgy, chemical, flue gas, electronics, food, plastics, welding processing, and precious metal recycling.

Properties of Sintered Plates:

1. The sintered plate filter cores feature a rigid wavy porous structure, with a sintered plate thickness of approximately 4mm, creating uniform pores of about 30μm internally. Subsequently, a PTFE coating is applied in the gaps of the substrate surface through a special spraying process, forming micro-pores with a size of 2 to 3 μm.

2. An independent cavity sealing design ensures that even if there is air leakage in the sintered plate filter, it will not lead to widespread dust emissions and resultant environmental pollution.

3. The unique wavy design of the plastic sintered plate filter core increases the filtering area while reducing the occupied space.

4. High Dust Removal Precision: Micron-level filtration aperture, removing 99.9% of dust particles larger than 1um, and can effectively remove most particles larger than 0.1um.

5. Large Filtration Area: The corrugated design of the filtration surface offers 3 to 6 times the filtration area in the same volume compared to a filter bag.

6. Strong self-cleaning ability: The rigid structure allows the reverse blowing gas to act more directly on the powder adhered to the filter surface, without any buffer, achieving thorough dust removal.

7. Hydrophobic and oleophobic: The sintered plate substrate is made of various high polymer materials with different densities, and the PTFE coating penetrates deep into the pores of the sintered plate substrate, forming a super-fine pore anti-adhesive structure, which exhibits hydrophobic and oleophobic properties.

8. Strong resistance to acids and alkalis: Special resin material can withstand long-term high-temperature corrosion by strong acids and alkalis.

9. Constant pressure, stable resistance; as the wave-shaped sintered plate filter core captures dust through the surface resin coating, its smooth surface makes it extremely difficult for dust to penetrate or linger. Even if some extremely fine dust particles manage to enter the cavity, they are immediately blown away by the set pulse compressed air flow. Therefore, there is no clogging phenomenon in the sintered plate filter core matrix.
