Air acidification health risk prevention - uses artificial dephlegmation to purify polluted air at high altitudes for pumping into room space

摘要

For improving the environment and reducing health hazards caused by polluted air. Polluted air is exposed to artificial dephlegmation, i.e. artificial rain is created at an altitude such as to re-establish fresh air pH = 7.5. Air is removed by suction from closed rooms. Care is taken to re-absorb fresh air having pH = 7.5. The spent air is refreshed directly by spraying suitable solns. to establish fresh air pH = 7.5. Health risks, partic. cancer hazard, caused by exposure to an over-acidified atmos., can be overcome. The first process purifies atmos. polluted by motor fumes.
