Abstract
The utility model discloses an SCR (selective catalytic reduction) device with a single reactor. Great space is needed for arranging dual reactors in the prior art; many steel structures and reaction protective plates are used, for part of reconstruction projects, the arrangement of dual reactors cannot satisfy the requirements of the original steel structure and foundation. Flow field uniformity at reactor inlets of the dual-reactor arrangement is poor, so many guide plates need to be arranged. The SCR device with the single reactor comprises two coal economizer outlet flues, wherein the coal economizer outlet flues are respectively connected with reactor inlet flues (2); the reactor inlet flues are connected with the single reactor (3) of the SCR device; the single reactor of the SCR device is arranged on a reactor supporting beam 4; and the single rector of the SCR device is connected with an air pre-heater. The single reactor disclosed by the utility model is used for the reactor of a boiler SCR.
