Hopcalite Catalyst: Guardian of air purification in Metro stations

As an urban transportation hub, subway stations are faced with severe air pollution problems due to large passenger flow and relatively closed space. Major exhaust gases include carbon monoxide (CO), nitrogen oxides (NOx) and volatile organic compounds (VOCs). These pollutants mainly come from train braking, power equipment operation and passenger activities. Long-term exposure to this environment can cause respiratory diseases and endanger public health.

There are many challenges to cleaning the air in subway stations. The narrow space leads to uneven diffusion of pollutants; The concentration of pollutants increases sharply due to the dense flow of people during peak hours. Traditional ventilation system has high energy consumption and limited purification effect. In addition, the complex environment of the subway station requires high stability and long service life of the purification equipment.

The application of hopcalite catalyst provides an innovative solution for air purification in subway stations. The catalyst can efficiently oxidize CO and VOCs at room temperature, while reducing NOx to harmless nitrogen. By optimizing the catalyst formulation and carrier structure, the performance of sulfur and water resistance was improved and the service life was prolonged. By combining the catalyst with the intelligent ventilation system, on-demand purification can be achieved, significantly reducing energy consumption.

The application of hopcalite catalyst in subway stations should be noted:

Reasonable arrangement of catalyst units to ensure full coverage of purification effect

Multi-parameter air quality monitoring system is installed for precise control

Regular maintenance of catalysts to maintain efficient purification capacity

Combined with the fresh air system, the air distribution in the station is optimized
