Zusammenfassung: | The invention provides matrix type selective catalytic reduction flue gas denitration equipment. The matrix type selective catalytic reduction flue gas denitration equipment is provided with an ammonia spraying branch main pipe matrix, an effluent gas nitrogen oxide concentration detector matrix and an ammonia concentration detector matrix, wherein the ammonia spraying branch main pipe matrix and the effluent gas nitrogen oxide concentration detector matrix are the same in distribution and located on the upstream of a catalytic reduction reactor. The invention further provides a matrix type selective catalytic reduction flue gas denitration method. The accurate measurement and feedback control of flue gas flow, nitric oxide and ammonia concentration can be realized, so that the ammonia spraying amount is reduced to the greatest extent under the condition of meeting the emission standard, and the problem of high ammonia escape is solved.
