Abstract

The embodiment of the invention discloses a coal-fired power plant denitration system. The system has an SCR reactor. The SCR reactor is equipped with an on-line monitoring device. The on-line monitoring device includes a sampling main pipe, the sampling main pipe is provided with a plurality of sampling branch pipes at an interval of preset distance along the flow direction of flue gas, and the sampling branch pipes are equipped with a plurality of sampling holes. The coal-fired power plant denitration system disclosed by the embodiment of the invention solves the technical problems that under the circumstance of a non-uniform flue gas flow field, the data measured by single-point sampling of existing on-line monitoring devices is inaccurate and not representative.

Description

technical field [0001] The present application relates to the field of coal-fired denitrification technology, in particular to a coal-fired power plant denitrification system. Background technique [0002] For large-capacity units, such as 1000MW units, the denitrification system is usually equipped with an online monitoring device for flue gas. The online monitoring device is set in the SCR reactor to monitor the concentration of each component of the flue gas in real time. [0003] For some units, due to the limitation of installation conditions, the straight pipe section of the online monitoring measurement point may not be able to meet the standards of 6D and 3D before and after the straight pipe section (D is the diameter of the pipe section). If the standard is not met, the flue gas flow field in the straight pipe section may be uneven. In the existing on-line monitoring device, the sampling of the denitrification SCR flue gas inlet and outlet is in the vertical flue...
