The invention discloses an SCR reactor flow equalizing device, a control method and a system. The flow equalizing device comprises a control device and a movable or rotatable flow guide plate arrangedin a flue of a SCR reactor; the control device is connected with the flow guide plate and is used for controlling the flow guide plate to move or rotate so as to adjust the flow direction of flue gasat the bent position of the flue. According to the SCR reactor flow equalizing device provided by the invention, the flow guide plate in the flue of the SCR reactor is set to be rotatable or movable,the flow direction in the flue is set to be in an adjustable state, the flow guide plate is adjusted through the control device, the flue with the fixed flow direction in the prior art can be adjusted into the flue with the variable flow direction, and the problem that the denitration efficiency is low due to the fixed flow direction is solved. According to the control method and the system, theopportunity for adjusting the flow guide plate can be accurately selected, the position of the flow guide plate is adjusted according to the flow guide effect, the flow guide plate can be accurately adjusted in place, and the flow field uniformity can meet the requirement.
Description
technical field [0001] The invention relates to the technical field of flue gas denitrification, and more specifically relates to a flow equalizing device for an SCR reactor. In addition, the present invention also relates to an SCR reactor flow equalization control method and control system. Background technique [0002] In the flue gas denitrification device, the SCR method is the most widely used method. It has the advantages of large amount of flue gas treatment, high efficiency and stable operation. The SCR method is to arrange the catalyst required for the denitrification reaction in the flue area where the flue gas temperature is generally 120-420 °C. The flue gas is fully mixed with the reducing agent (generally ammonia) injected into the flue before passing through the catalyst. When the flue gas passes through the catalyst, the NO in the flue gas will X React with reducing agent to generate harmless N 2 and water to remove NO from the flue gas X . [0003] The...
