With the acceleration of industrial development and urbanization, the problem of air pollution is becoming increasingly severe, especially chemical pollutants such as volatile organic compounds (VOCs), acidic gases, and odors, which pose a threat to health and the production environment. In response to this challenge, modular chemical filters have become an ideal choice in industrial, medical, electronic manufacturing, and other fields due to their high efficiency, flexibility, and ease of maintenance.
Product Introduction
The modular chemical filter adopts a multi-layer composite filter material design, and the core filter media includes:
Activated carbon layer: adsorbs organic pollutants such as benzene and formaldehyde;
Chemical impregnation layer: for catalytic decomposition of specific gases (such as SO ₂, NOx, NH3);
HEPA pre filter layer (optional): intercepts particulate matter and extends the lifespan of chemical filters.
Its modular structure supports quick replacement of filter elements and can flexibly combine filter units according to pollution types to meet the needs of different scenarios.
Application areas: from factories to data centers
Industrial manufacturing
Semiconductor factory: Filter acidic gases (HF, HCl) generated by etching processes to protect precision equipment.
Chemical workshop: deals with VOCs emissions and complies with EPA and GB 31571-2015 standards.
Medical and Laboratory
Hospital operating room: Remove disinfectant residues (such as hydrogen peroxide) and anesthetic gases.
Biological laboratory: Control formaldehyde and ammonia to ensure personnel safety.
Business and Public Facilities
Data center: prevent servers from being damaged by corrosive gases such as H ₂ S.
Subway Station: Eliminate tunnel odors and enhance passenger experience.
special environment
Military chemical defense: Integrated CBRN (chemical, biological, radiological, nuclear) protection system.
Usage: Three steps to achieve efficient purification
Selection and Configuration
Select the type of filter cartridge based on the target pollutant (such as KMnO ₄ impregnated carbon for formaldehyde and iodized carbon for mercury vapor).
Calculate the air volume requirement and match the filter size (e.g. 4 × 600 × 600mm modules are required for a 2000m ³/h air volume).
Installation And Maintenance
Installation: Embedded in AHU (Air Handling Unit) or used independently to ensure a sealed and leak free environment.
Replacement cycle:
Activated carbon filter cartridge: 6-12 months (in an environment with a VOC concentration of 10ppm);
Chemical impregnated filter cartridge: 3-6 months (for highly corrosive gases).
Monitoring prompt: Equipped with a differential pressure sensor, it needs to be replaced when Δ P>150Pa.
Performance Verification
Use a PID detector to measure the VOC concentration at the inlet and outlet, ensuring a removal rate of>90%.
Regularly conduct ISO 10121-3 standard testing and issue compliance reports.
Industry case: VOC treatment of a certain automotive coating factory
Problem: The benzene emissions in the paint spraying workshop exceed the standard (detection value of 50mg/m ³, exceeding the national standard by three times).
Solution:
Configure two-level module filters:
Pre zeolite wheel for VOCs concentration;
Rear KMnO ₄+activated carbon composite filter cartridge.
Effect: Emissions reduced to 5mg/m ³, saving 1.2 million yuan in RTO incineration energy consumption costs annually.
