Inquiry (采购产品): Tunnels Air Purification Dear Sirs, Greetings. This subject is highly requested: Is there any commercial process in a big scale to absorb the Road Air Pollution Oxides Contaminants as Carbon Oxides (CO & CO2) in addition to {Nitrogen Oxides+Sulfur Oxides} emitted from the exhaust combustion systems from "Cars, Wagons, Trucks, Buses" which uses Gasoline or Gas oil or Diesel oil as fuels. These pollution Gases (Carbon, Nitrogen and Sulfur Oxides) need to be removed in a big scale from Air in a long crowd Tunnel of length reaches one Kilometer or more. These toxic Gases are still present in the Tunnels although they use Huge Fans to push the polluted Air out. So, I think that one of the solutions is to use Oxide Absorbers. How can your society provide the latest of these Absorbers or Electrostatic Precipitators or any other facility (with its Oxides Measuring Devices) to clean and purify the air inside the Tunnels continuously to cope with the International Clean Air Standards ??. The solution will be accepted especially if the absorbing materials (Char-Coal or Silica-Gel or Molecular Sieves or others) or catalysts could be recycled and backed up with regard to economic point of view. Please send me your thoughts, the simple technical theory to be used, approximate number of filters units needed to cover the whole Tunnel ( 1 Kilometer length & 7 meters height), approximate cost of each unit. If this subject is not in your area of technology, please advise us with the other specialized international companies. Thanks in advance to send us the required information ASAP. Regards.
