A method and device for waste gas dedusting and a dedusting agent used in the method. A dust-containing waste gas () and an organic dedusting agent () are introduced into a dedusting tower (), respectively, and make contact with each other in the tower; at least part of the water vapor in the dust-containing waste gas () is condensed, and the organic dedusting agent () and the condensed water adsorb solid particles, acidic pollutants, organic pollutants and/or heavy metal compounds in the dust-containing waste gas; and the resulting purified gas () is emptied out or subjected to a subsequent process. The organic dedusting agent () comprises a non-toxic and high boiling point organic solvent composition, being two or more selected from cooking oil, silicone oil, modified silicone oil, liquid-state asphalt oil, tung tree seed oil, liquid-state paraffin wax oil, mineral oil, palm oil and waste cooking oil.

Method for waste gas dedusting and dedusting agent

A method for removing SO(x=2 and/or 3) from gas using a solution having polyethylene glycol as the main ingredient. First, SOin the gas is absorbed by the solution of polyethylene glycol. Second, the solution of polyethylene glycol which has absorbed SOis regenerated by one or more of the heating, vacuum, ultrasonic, microwave or radiation methods, thereby releasing the by-products of sulfur dioxide and sulfur trioxide. The regenerated solution of polyethylene glycol is recycled. When the water content of the regenerated solution of polyethylene glycol is high enough to affect the desulfurization, it needs to be removed. Removal methods include heating and rectification, absorption using a water absorbent, or a combination of these methods. The polyethylene glycol solution is recycled after dehydration.
