Variable bidirectional electrostatic filter system with adjustable distance between charging part and dust collecting part

A variable bidirectional electrostatic filter system with an adjustable distance between a charging part and a dust collecting part, the variable bidirectional electrostatic filter system comprising:

• a high voltage applying means configured to supply a high voltage;
• a filter housing configured to provide a flow path through which contaminated air flows in a forward direction or a reverse direction and to provide an installation space therein;
• a dust collecting part installed in the filter housing and made by alternating dust collecting electrodes and voltage plates in parallel, the dust collecting electrode being formed of an grounded metal plate and configured to capture charged fine particles, and the voltage plates being formed of a metal plate connected to the high voltage applying means and configured to form an electric field;
• a first charging part configured as an ionizer installed in a first direction of the dust collecting part, connected to the high voltage applying means, and having multiple protrusions formed in a serrated shape having a predetermined length in a longitudinal direction to charge fine particles through corona discharge;
• a second charging part configured as an ionizer installed in a second direction, which is opposite the first direction of the dust collecting part, connected to the high voltage applying means, and having multiple protrusions formed in a serrated shape having a predetermined length in the longitudinal direction to charge fine particles through corona discharge;
• a first movement rail installed on the filter housing, fastened so that the first charging part is moved in the first direction and in the second direction, and configured to adjust a distance from an amplification section while forming the amplification section between the first charging part and the dust collecting part;
• a second movement rail installed in the filter housing, fastened so that the second charging part is moved in the first direction and in the second direction, and configured to adjust a distance from an amplification section while forming the amplification section between the second charging part and the dust collecting part;
• and
• a control unit configured to control an operation of the high voltage applying means.
