Abstract

An air pollution prevention system is disclosed and includes at least one detection and processing device and at least one cleaning device. The detection and processing device includes a nano actuator, a nano photodetector, a carbon nanotube and a microprocessor, which are integrated as a single chip device through semiconductor manufacturing processes. The detection and processing device configured to detect a particulate matter and gas contained in an air pollution source and output a control command. The cleaning device includes a nano blower, a nano filter and a controller. The cleaning device receives the control command outputted from the detection and processing device through the controller to control the nano blower for guiding the air pollution source to flow through the nano filter for filtration.
