Dust collecting tower apparatus

A dust collecting tower apparatus for collecting fine dust contained in air, the apparatus comprising:

• a housing having an inlet, into which gas is introduced, and an outlet from which the gas is discharged;
• a collection module disposed in the housing and configured to collect particulates with a corona discharge, the collection module comprising a plurality of discharge electrodes, to which a voltage is applied, and a plurality of collection electrodes disposed between the discharge electrodes, the collection electrodes coupled to a ground;
• a washing water feeder configured to spray washing water to the collection module;
• and
• a washing water treatment device disposed beneath the collection module to scrape off dust attached on an adsorption belt to separate the scraped dust from the adsorption belt, the adsorption belt installed in a reservoir configured to accommodate the washing water dropping from the collection module.
