Introduction to Fume, Oil, and Dust Treatment Equipment
The Sintered Plate Dust Collector, also known as the Sintered Plate Dust Collector, utilizes wavy sintered filter sheets made from a blend of various high polymer powder compounds. After casting and sintering, a porous matrix is formed. This matrix is then treated with a special spraying technique to fill the gaps in the sintered plate matrix with ultra-fine dust particles measuring less than 1-2 micrometers, ensuring high dust removal efficiency and ultra-low emissions, meeting the smoke and dust emission concentration requirement of 3-5 mg. It is particularly suitable for the treatment of ultra-fine dust from coarse rolling machines. The sintered plate not only boasts high dust removal efficiency but also a long service life; domestically produced sintered plates have a lifespan of 8-10 years, while imported ones can last for more than 10 years. Additionally, it reduces the surface resistance of the filter plates.
Difference Between Pulverized Burn Plate Dust Collectors and Baghouse Dust Collectors:
The external shape of the molded board features a wavy pattern resembling the shape of an accordion box. When expanded into a flat surface, it triples the surface area. The internal structure of the wavy filter is divided into 17 cavities. This design, in addition to considering the strength of the components, is crucial for gas dynamics requirements, ensuring efficiency during the pulse airflow backflushing for dust removal. The dust collector assembled with this material occupies only 1/2 to 1/3 of the space of a bag dust collector with the same filtering area. The overall structure is also reduced accordingly, showcasing a space-saving characteristic.

Due to the wave-shaped sintered plate capturing dust through its PTFE-coated surface, its smooth surface makes it difficult for dust to penetrate or remain. Even if some extremely fine dust particles might enter the gaps, they are promptly blown away by the set pulse compressed air flow. Therefore, there is no clogging in the filter plate matrix, and the pressure loss of the filter element stabilizes and remains constant after a very short period of time. This indicates that the resistance loss of a specific powder under specific temperature conditions is only related to the filter air velocity and does not increase over time. Consequently, the treated air volume of the dust collector does not change over time, ensuring consistent air intake and dust removal efficiency.
Hydrophobicity of smoke, oil, and dust removal equipment
Due to the completely hydrophobic nature of the materials and coatings used in the filter media, when water is sprayed onto it, an interesting phenomenon occurs: water droplets gather and flow down as a stream. This is no longer the case with fiber fabric filter bags, which, due to their moisture-absorbing properties, form a water film and adhere dust, causing an overall increase in resistance. Such a situation does not exist in sintered plate dust collectors. This will result in excellent performance for handling smoke and dust from condensation, as well as highly hygroscopic dusts like ammonium phosphate, calcium chloride, soda ash, and mirabilite.
The rigid structure of sintered boards eliminates the lifespan issues caused by frame wear in fiber fabric filter bags. Another significant indicator of long lifespan is the long period of trouble-free operation of the filter sheets, which do not require frequent maintenance or care. The good dedusting characteristics maintain a stable resistance, ensuring the sintered board dust collector operates effectively over a long period. In fact, the lifespan of a sintered board dust collector that was introduced 87 years ago has not yet required a filter sheet replacement. Even if a filter sheet is damaged by an accidental factor, it can continue to be used with special bonding, without any negative impact from a small bonding seam. The sheet itself has inherent rigidity and toughness, requiring no internal frame support. Its pressure, corrosion, wear, and air impact resistance are significantly greater than that of fabric bags, thus offering a longer lifespan, typically over 10 years.
Principle of dust removal for plastic sintering board filters:
The dust collector employs pulse online cleaning, eliminating the need for shutdown. During operation, the dust cleaning control operates based on a combination of time and pressure differential methods, with automation by the PLC system ensuring the dust collection system maintains optimal running conditions. When the dust collector discharges, a comprehensive control method is used, depending on the amount of dust, with a high material level sensor installed in the ash collection bin. An alarm is displayed in the control cabinet when the dust level in the bin reaches the high material level.
Sintered plates are the main components of sintered plate dust collectors, where they perform the tasks of gas-solid and liquid-solid separation.

Under normal conditions, the dust concentration at the intake can reach up to 300g/m³, while the dust concentration in the exhaust can be controlled below 5mg/m³. In high-efficiency dust removal systems, the dust removal efficiency reaches 99.99%. It is widely used in industries such as rolling steel, metallurgy, chemical, flue gas, pharmaceuticals, electronics, food, die-casting aluminum, plastics, welding processing, and precious metal recycling.
