| 摘 要： | Removal of SO2 and NOx by pulsed corona combined with in situ alkali absorption was experimentally investigated.In the reactor,a plate-wire-plate combination is devised for generating pulsed corona and then alkaline absorbent slurries were introduced into the reactor by a continuous band conveying system to capture the gaseous reaction products.It was found that both SO2 and NO could be removed by corona combined with in situ alkali absorption.The removal of SO2 increased to 75%with the corona discharge,compared with 60%removal only with Ca(OH)2 absorption.About 40%removal of NO was reached by pulsed corona combined with in situ Ca(OH)2 absorption.It was found that SO2 and NO in the gas stream are oxidized to SO3 and NO2 by pulsed corona respectively,and then absorbed by the alkali in the reactor.The removals of SO2 as well as NO were higher with Ca(OH)2 as the absorbent,compared with using CaCO3 or ZnO.

| Abstract: | Removal of SO2 and NOx by pulsed corona combined with in situ alkali absorption was experimentally investigated. In the reactor, a plate-wire-plate combination is devised for generating pulsed corona and then alkaline absorbent slurries were introduced into the reactor by a continuous band conveying system to capture the gaseous reaction products. It was found that both SO2 and NO could be removed by corona combined with in situ alkali absorption. The removal of SO2 increased to 75% with the corona discharge, compared with 60% removal only with Ca(OH)2 absorption. About 40% removal of NO was reached by pulsed corona combined with in situ Ca(OH)2 absorption. It was found that SO2 and NO in the gas stream are oxidized to SO3 and NO2 by pulsed corona respectively, and then absorbed by the alkali in the reactor. The removals of SO2 as well as NO were higher with Ca(OH)2 as the absorbent, compared with using CaCO3 or ZnO. |
