The magic of carbon monoxide catalysts in underground parking lots

As a closed space, the underground parking lot faces serious air pollution problems. Vehicle exhaust is the main source of pollution, in which the concentration of carbon monoxide (CO) often exceeds the standard. CO has a strong ability to combine with hemoglobin, which will reduce the oxygen-carrying capacity of the blood, cause headaches, dizziness and other symptoms, and can lead to coma or even death in severe cases. In addition, pollutants such as nitrogen oxides and hydrocarbons in exhaust gas can also cause harm to human health.
There are multiple challenges to air purification in underground parking lots. Space closure leads to easy accumulation and difficult diffusion of pollutants; The fluctuation of traffic flow results in the great change of pollutant concentration. Ventilation systems have high energy consumption and limited effectiveness. It is difficult for traditional methods to achieve energy saving and environmental protection while ensuring air quality.
The application of carbon monoxide catalysts provides an innovative solution for air purification in underground parking lots. The noble metal catalyst can efficiently oxidize CO to harmless CO2 at room temperature, and the conversion rate can reach more than 95%. By optimizing the catalyst support and active components, the performance of sulfur and water resistance was improved and the service life was prolonged. The combination of catalyst and ventilation system can greatly reduce energy consumption and realize intelligent control.
To maintain clean air in underground car parks, comprehensive measures are required:
Reasonable design of ventilation system, optimize air flow organization
The CO concentration monitoring device is installed to realize real-time monitoring
Maintain catalyst regularly to ensure purification efficiency
Promote the use of new energy vehicles to reduce pollution at source
The promotion and application of carbon monoxide catalyst has significantly improved the air quality of underground parking lots and guaranteed public health. This technology not only improves the safety of space use, but also provides a new idea for urban environmental governance. With the advancement of technology and application, catalysts will play an important role in more fields.
