Glass fiber mixed wire mesh demister
Glass fiber mixed wire mesh demister
The glass fiber mixed wire mesh demister is made of high-strength glass fiber and chemically stable synthetic fiber through a special weaving process. Compared with traditional metal demisters, it has the corrosion resistance, acid and alkali resistance of non-metallic demisters and maintains high-efficiency fog capture capabilities. It is an ideal choice for chemical demisters, pickling towers, spray towers and other gas-liquid separation systems.

Product Features and Benefits
Excellent corrosion resistance: The glass fiber body has almost no chemical reaction to acid and alkali media, and the synthetic fiber further enhances the overall chemical stability, which is suitable for corrosion-resistant defoaming pads.
Efficient droplet capture: The precision mixed structure forms layers of fiber mesh, and the droplets continue to collide and coalesce between the meshes, with a separation efficiency of more than 98%.
Low pressure drop design: Compared with the metal mesh defoamer, the non-metallic defoamer has a larger ventilation channel, significantly reduced pressure drop, and saves fan energy consumption.
Lightweight and easy to maintain: The weight is only 1/5 of the metal defoamer, and it is more convenient to install and disassemble on site; it can be directly replaced or cleaned when blockage occurs.
Wide operating conditions: It can work stably in the temperature range of -50 ℃ to +200 ℃, as well as in highly corrosive and humid environments, meeting the needs of various chemical processes.
Product application industry
Chemical and fine chemicals: high-efficiency chemical demisters for pickling towers, nitrification systems, and solvent recovery towers.
Environmentally friendly waste gas treatment: spray scrubbers, desulfurization and denitrification device tail gas demisting, protecting subsequent catalysts and heat exchangers.
Pharmaceuticals and bio-fermentation: composite wire mesh demisters in fermentation tank gas outlets and sterile gas purification systems.
Electroplating and surface treatment: acid mist recovery, waste gas capture, and reduction of acid mist pollution in plant buildings.
Seawater desalination and water treatment: multi-stage spray towers, droplet interception and droplet reflux in degassing towers.
FAQ
Under normal temperature, pressure and acid-base concentration not exceeding 30%, the normal service life can reach 3-5 years. In case of extremely high temperature or high concentration of corrosive gas, it is recommended to check regularly and replace it as appropriate.
Use a low-pressure water gun or mild chemical cleaning agent to rinse, and avoid high pressure directly impacting the fiber mesh; after cleaning, dry naturally or dry at low temperature.
Non-metallic demisters have stronger corrosion resistance, light weight, and low pressure drop. Glass fiber composite demisters are especially recommended in situations where stainless steel is susceptible to corrosive environments.
The thickness and wire diameter are determined by the gas velocity, droplet volume and process temperature. Generally, 100 mm thickness is suitable for medium loads, and 0.15 mm wire diameter is suitable for separating fine droplets. LiandaFiltration can provide professional selection support.
