The difference between plastic sintered plate filter media and bag filter media:
The external shape of the plastic sintered plate features a wavy pattern akin to an accordion box. If expanded into a flat surface, it triples the surface area. The internal structure of the wavy filter plate is divided into 17 cavities. This design, while considering the strength of the components, is primarily driven by aerodynamic needs to ensure efficiency during pulse jet backflushing for dust removal. The dust collector assembled with this material occupies only 1/2 to 1/3 of the space of a bag-type dust collector with the same filtration area. The overall structure is also reduced accordingly, offering space-saving benefits and creating conditions for user-friendly factory design and cost reduction in total equipment investment.
Sintered Plate Model:
Model: NLDN-9M Type
Dimensions: 1550(L) × 1050(W) × 61(H), single board filtration area: 9.0㎡
Model: NLDN-4.5M Type
Dimensions: 1500(L) × 565(W) × 80(H), single plate filtration area: 4.5㎡
Common temperature resistance of sintered plates is: 70℃ (room temperature)
Special performance sintered boards: Acid-resistant, antistatic, 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 is up to 99.99%. Widely used in industries such as rolling steel, metallurgy, chemicals, flue gas, electronics, food, plastics, welding processing, and precious metal recycling.
Properties of sintered plate:
The sintered plate filter core features a rigid wavy porous structure, with a sintered plate thickness of approximately 4mm. Internally, it forms a uniform pore size of about 30μm. Subsequently, a PTFE coating is filled into the gaps on the substrate surface through a special spraying process, creating micro-pores of 2 to 3 μm.
2. The independent cavity sealing design ensures that even if there is air leakage in the plastic sintered plate filter plate, there will be no large-scale dust emission causing environmental pollution.
3. The unique wavy design of the塑烧板滤芯increases the filtration area while reducing the footprint.
4. High dust removal accuracy: Micron-level filter pore size, capable of removing 99.9% of smoke and dust particles larger than 1um, and most of the particles larger than 0.1um.
5. Large Filtration Area: The corrugated design of the filtration surface offers 3 to 6 times the filtration area within the same volume compared to filter bags.
6. Strong self-cleaning ability: The rigid structure allows the reverse blowing gas to act more directly on the powdery material adhered to the filter surface, without any buffer, ensuring thorough dust removal.
7. Hydrophobic and oleophobic: The sintered plate substrate is made of various high molecular materials with different densities sintered together. The PTFE coating penetrates deeply into the pores of the sintered plate substrate, forming a super-fine pore anti-adhesive structure, which exhibits hydrophobic and oleophobic properties.
8. Excellent Acid and Alkali Resistance: The special resin material can withstand long-term high-temperature corrosion from 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 remain. Even if some extremely fine dust particles might enter the cavity, they are immediately blown away by the set pulse compressed air flow. Therefore, clogging does not occur within the sintered plate filter core matrix.
