Title:
ELECTROSTATIC AIR CLEANING MEANS WITH A WIND MOTOR
Document Type and Number:
WIPO Patent Application WO/1996/007482
Kind Code:
A1
Abstract:
An electrostatic air cleaning means integrally consists of a wind motor and an electrostatic air cleaner. The means is provided at the wind inlet and outlet of a ventilation system, especially an air conditioning system. The fans of the wind motor are rotatably driven by the wind output so that electricity can be generated by the electricity generator associated with the wind motor. The voltage of electricity is increaased by a dc converter and then is rectified and multiplied into a high voltage dc output. The cleaner includes a primary metal filter screen, a filter screen, ionizer wires, dust collecting plates, a high voltage metal axis etc. The electrostatic air cleaning means of this invention does not need any external electric power as a result of utilizing electricity generated by the wind output from the system. Not only energy consumption is greatly decreased but process and the wind delivering process are automatically ensured because the operation of the wind motor is directly controlled by the ventilation system,especially by the wind input and output of air conditioning system.
