It uses laser engraving machines, automatic welding and splicing machines, injection molding machines for mechanized mass production, and main products include permanent magnet energy-saving fans, PP flame-retardant spray towers, PP flame-retardant activated carbon adsorption devices, etc., applied in PCB, electroplating, chemical, pharmaceutical, food and other industries.
How Often to Replace Activated Carbon in Adsorption Towers? The 3-6 Month Basis
For the activated carbon replacement cycle of adsorption towers, the PP flame-retardant activated carbon adsorption devices from Huizhou Xicheng Environmental typically have a 3-6 month cycle, based on the following key indicators:
- Waste gas concentration
- Air volume
- Carbon layer thickness
- Iodine value (≥800 mg/g)
- Adsorption efficiency (≥85%)
- Outlet waste gas test results
These indicators together determine the saturation level of activated carbon, thus setting the replacement time. If adsorption efficiency is below 85% or outlet test results are substandard, replacement is needed in advance; if indicators remain stable, the cycle can last up to 6 months.
Convenient Drawer-Type Carbon Replacement Design
To simplify the replacement process, this PP flame-retardant activated carbon adsorption device adopts a drawer-type design, making replacement easy without complex tools, reducing maintenance cost and time, and adapting to waste gas treatment needs of multiple industries.
