Scrubber, exhaust gas purification system comprising scrubber, and air purification method

An exhaust gas purification system, comprising:

• a scrubber, wherein treatment water of the scrubber is plasma electrolytic water prepared by electrolyzing water;
• an electromagnetic water treatment device including a water flow passage, at least one positive pole panel and at least one negative pole panel disposed on opposing sections of the water flow passage, and a cation exchange film disposed within the water flow passage and located between the at least one positive pole panel and the at least one negative pole panel to thereby divide the water flow passage into a first water flow passage and a second water flow passage;
• a water tank;
• and
• a filter, wherein the filter, the water tank, the electromagnetic water treatment device, and the scrubber are connected to one another;
• the electromagnetic water treatment device further including a magnetic device having at least one pair of magnetic sheets adheringly disposed on two opposing outer walls of the water flow passage, whereby respective electric fields generated by the at least one positive and negative pole panels electrolyze water in the first and second water flow passages, and a magnetic field generated by the at least one pair of magnetic sheets is in a direction perpendicular to a direction of the electric fields generated by the at least one positive and negative pole panels in the first and second water flow passages thereby generating the plasma electrolytic water.
