Air Pollution Scrubbers

Urban Street Air Cleaner

Air pollution control is critically absent in mega-cities like Delhi and Shanghai. Riding a motorized rickshaw in India for example, or a bus in China often leaves the rider with polluted air to breathe. In Mexico City tourists find the same is true. In Tokyo there are street-side vending units for oxygen masks, but no street-air cleaning devices can be found.

Urban Street Air Cleaners are pollution scrubbers specifically developed by Industrial Environmental Carbon to receive significant volumes of street air, and to safely treat the polluted air with chemical solutions containing potassium hydroxide, activated carbon, calcium hydroxide, and water.

Street air pollution from vehicle exhaust is ducted to a tower located either above or below ground (illustrated above). The tower unit's energy drives five regions of pollution control. The first treatment is particulate, ash, and hydrocarbon traps followed by CO₂ capture, and rainchamber clean. Further up are two separate rinse circuits which end with a cooling demister before clean air is driven from the top in continuum, as more air enters from the bottom.

Our pollution control, air purification towers are crafted to operate by convection forces alone - radiant heat-driven, or by solar, or wind, wave, or by grid-connected power. The towers may be installed in cities and remote desert or marine locations.

Measurements of the quantity of air impurities entering the tower are compared to those exiting from the top. We employ 5-gas analyzers for data collection, storage, and on-demand GPS viewing in real time.

The amount of carbonate collected from the captured CO₂ is an important industrial commodity.

C8H18 + 2O2 --> energy + CO2 + 2H2O [add KOH] CO2 + 2H2O --> KHCO3 [add KOH] KHCO3 + H2O --> K2CO3 carbonate.

In addition, the potassium content of the carbonate paste, is in itself an important agricultural product because potassium is one of the major nutrients needed by plants. Potassium compounds are therefore important in fertilizers.

All patent-pending systems reuse self-contained chemical and water solutions from reservoirs featuring conservative operation with carbonate production as a by-product. The carbonate may be mixed with selected aggregates to form bricks or cement as an added benefit.

A water source is a requirement. All systems demand supervision and maintenance.

All systems are available upon request.
