New Energy Industry

Typical Applications

Utilizing high-pressure resistant and corrosion-resistant materials such as special stainless steel and ceramics, filtration systems provide stable impurity interception under extreme conditions, including hydrogen refueling stations and photovoltaic silicon material production. This not only effectively prevents poisoning of fuel cell membrane electrodes and dust contamination in lithium battery drying rooms but also enables the recycling of valuable raw materials through high-precision powder capture. This purification method, which requires no chemical reagents, consumes little energy, and produces no secondary pollution, perfectly aligns with the new energy industry's pursuit of ultra-high purity,

Hydrogen Energy Industry: The "Purity Gatekeeper" of the Entire Industry Chain

Hydrogen's tiny molecular size and high flammability and explosibility impose stringent requirements on the filtration system's sealing and material compatibility.

In hydrogen production via electrolysis, the filtration system separates alkaline droplets or moisture from the hydrogen/oxygen generated by the electrolyzer. It also removes trace impurities before the drying process, preventing downstream catalyst poisoning. At the fuel cell end, the fuel cell stack is highly sensitive to the quality of incoming air. The filtration system has to simultaneously eliminate dust, salt spray, and trace chemical contaminants like SOx and NOx from the air to safeguard the membrane electrode assembly (MEA) from damage.

Lithium - ion battery manufacturing: The ultimate pursuit of cleanliness and dryness

The manufacturing processes of lithium - ion batteries have exceptionally strict environmental demands. Filtration systems play crucial roles in several stages.

During the positive and negative electrode material conveying, especially in pneumatic conveying of powder materials, high - efficiency bag or cartridge filters capture valuable raw materials. They prevent dust cross - contamination and protect the workshop environment. In coating and drying rooms, lithium - ion battery drying rooms employ a large - scale molecular sieve rotor + high - efficiency filter combination system. This system controls the air dew point below - 40°C and ensures a cleanliness level of 10,000 or 1,000, preventing moisture and impurities from causing battery self - discharge. Before the electrolyte filling process, precision physical filters remove extremely small suspended particles from the electrolyte.

Photovoltaic (Solar Energy) Industry: Ensuring the Supply of High - Purity Silicon

In polycrystalline/monocrystalline silicon production, whether through the Siemens process or the silane process, a large amount of corrosive and high - purity gases are involved. The filtration system uses ceramic or sintered metal filter elements to intercept silicon powder under high - temperature conditions, ensuring the silicon material purity reaches "11 nines" (99.99%). During the PECVD coating process at the cell coating stage, the filtration system guarantees the absolute purity of special process gases such as silane and ammonia. This prevents particles from forming "hot spots" on the silicon wafer surface.
