Abstract
A method and device for waste gas dedusting and a dedusting agent used in the method. A dust-containing waste gas (1) and an organic dedusting agent (4) are introduced into a dedusting tower (3), respectively, and make contact with each other in the tower; at least part of the water vapor in the dust-containing waste gas (1) is condensed, and the organic dedusting agent (4) 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 (2) is emptied out or subjected to a subsequent process. The organic dedusting agent (4) 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.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
