| titleOfInvention | A system for reducing nitrogen oxides in tail gas |
| abstract | The utility model discloses a system for reducing nitrogen oxides in tail gas, which comprises: a sodium nitrite mother liquid heater, one end of the sodium nitrate mother liquid heater is connected to the sodium nitrate mother liquid to be treated, and the other end is connected to the middle part of a conversion washing cooling tower; The conversion washing cooling tower is connected to the conversion separator and the conversion gas isothermal oxidation tower in turn through pipelines, and the NOx gas coming out from the top of the conversion gas isothermal oxidation tower is sent to several alkali absorption tower groups respectively through the conversion gas regulating valve, and passed through the conversion gas isothermal oxidation tower. The sodium carbonate solution in the alkali absorption tower group is absorbed. Through a series of devices and the arrangement of pipelines, the utility model can reduce the NOx in the tail gas at the outlet of alkali absorption through isothermal oxidation and precise gas distribution of the nitrogen oxides from the conversion process, and reduce the consumption of ammonia for the tail gas treatment device of subsequent environmental protection facilities. , thereby greatly reducing the consumption of product gas ammonia. |
