| titleOfInvention | The processing method of the process tail gas containing NOx |
| abstract | The invention discloses a kind of processing methods of process tail gas containing NOx, including following content: (1) process tail gas containing high concentrate NOx being introduced stair oxidation device and carry out oxidation processes；(2) process tail gas after stair oxidation and the absorbing liquid from primary cycle tank are introduced into rotating packed bed reactor respectively, in rotating packed bed reactor, process tail gas and absorbing liquid hybrid reaction, part NOx is absorbed in process tail gas, and absorbing liquid returns to primary cycle tank and is recycled；(3) treated residual exhaust is absorbed through step (2) introduce secondary oxidation device carry out oxidation processes, absorbing liquid in secondary cycle tank is divided into branch 1 and branch 2 after secondary cycle pumps, tail gas and branch 1 after secondary oxidation introduce efficient absorption tower, tail gas is handled through absorbing liquid absorption, absorbing liquid returns to secondary cycle tank, branch 2 enters absorbing liquid hybrid reaction in primary cycle tank, with primary cycle tank, the qualified discharge after demisting of tail gas after processing.This method urea absorption effect is good, and high concentrate NOx technology tail gas after processing meets qualified discharge requirement, efficiently and without " three wastes " discharges. |
