Abstract

sistema e método para desnitrificação de gás residual por monóxido de carbono. a presente invenção se refere a um sistema e um método para desnitrificação de gás residual por monóxido de carbono, em que o sistema compreende um dispositivo de geração de ar quente (1), um reator de co (2), e um reator de scr (3); um primeiro duto (l1) e um segundo duto (l2) separados de um tubo de transmissão do gás residual original (l0) são respectivamente conectados em uma torre de reação principal (201) e um desvio (202) do reator de co (2); um terceiro duto (l3) conduzido para fora de uma saída de gás residual da torre de reação principal (201) do reator de co (2) e um quarto duto (l4) conduzido para fora do desvio (202) do reator de co (2) são combinados e, então, conectados no reator de scr (3) através de um quinto duto (l5); e uma saída de ar quente do dispositivo de geração de ar quente (1) é conectada no primeiro duto (l1) através de um sexto duto (l6). o calor liberado no processo de conversão de monóxido de carbono para dióxido de carbono alcança o propósito de aumentar a temperatura do gás residual para tratamento de desnitrificação, o que economiza o uso de combustível e também evita o problema de que o catalisador de co seja propenso à inativação quando encontrar óxido de enxofre em baixas temperaturas.system and method for denitrification of residual gas by carbon monoxide. The present invention relates to a system and method for denitrifying waste gas by carbon monoxide, wherein the system comprises a hot air generating device (1), a co reactor (2), and a scr reactor. (3); a first duct (l1) and a second duct (l2) separated from an original waste gas transmission tube (l0) are respectively connected in a main reaction tower (201) and a bypass (202) of the co reactor (2 ); a third duct (l3) leading out of a waste gas outlet of the main reaction tower (201) of the co reactor (2) and a fourth duct (l4) leading out of the bypass (202) of the co reactor (202). 2) are combined and then connected to the scr reactor (3) through a fifth duct (l5); and a hot air outlet from the hot air generating device (1) is connected to the first duct (l1) through a sixth duct (l6). The heat released in the process of converting carbon monoxide to carbon dioxide achieves the purpose of raising the temperature of the waste gas for denitrification treatment, which saves fuel usage and also avoids the problem that the CO catalyst is prone to inactivation when encountering sulfur oxide at low temperatures.
