Scrubbing apparatus

A scrubbing apparatus comprising:

• a scrubbing chamber defining a scrubbing space for scrubbing impurities contained in a gas;
• a separating wall dividing the scrubbing space into a first sub-space and a second sub-space;
• a spray nozzle disposed in the first sub-space, and spraying a first cleaning solution into the first sub-space;
• a scrubbing plate disposed in the second sub-space, and fixed to the separating wall;
• a cleaning solution supply nozzle disposed in an upper part of the second sub-space, and supplying a second cleaning solution to an upper surface of the first scrubbing plate;
• a cleaning solution storage tank installed in a lower part of the scrubbing chamber, and storing the first cleaning solution with the impurities dissolved therein and the second solution with the impurities therein;
• and
• a plurality of first scrubbing hole penetrating the first scrubbing plate,
• wherein a portion of the impurities contained in the gas is dissolved in the first cleaning solution in the first sub-space, and
• wherein another portion of the impurities contained in the gas is dissolved in the second cleaning solution on the upper surface of the first scrubbing plate after the gas ascends through the plurality of first scrubbing holes in the second sub-space.
