example 1

[0050] Taking the SCR denitrification reactor as an example, the upper, middle and lower layers of sampling pipelines are respectively installed at the inlet and outlet of the SCR denitrification reactor. The layout is as follows: figure 2 shown. Table 3 shows the measurement results of the inlet and outlet of the SCR denitration reactor:

[0051] Table 3 Overall performance evaluation of SCR denitration reactor measurement results

[0052]

[0053] From the measurement results in Table 3, it can be seen that the concentration of nitrogen oxides measured by the three-layer sampling pipeline has no obvious change, the SCR denitration reactor operates stably, and the system operates normally.

[0054] Specific measurement example 2: Judging the fault area of ​​the pollutant treatment device.

[0055] The catalyst in the middle area of ​​a certain SCR denitrification reactor is partially deactivated, and its inlet and outlet are equipped with an ordinary flue gas composition measuring device. The measuring point is single and the length of entering the reactor is insufficient. The results are shown in Table 4:

Abstract

The invention provides a device for detecting the performances of smoke pollution treatment equipment. A smoke inlet and a smoke outlet of the smoke pollution treatment equipment are respectively communicated with an equipment front smoke flue and an equipment rear smoke flue. The device comprises at least two groups of sampling pipes, wherein each group of sampling pipes comprise at least two sampling pipe layers. A smoke flue cross section where any sampling pipe layer is located comprises a plurality of equal areas, wherein one part of the equal areas are respectively provided with sample holes disposed on the sampling pipe layer, and the projections of sampling holes disposed on other sampling pipe layers are disposed at other part of the equal areas. The number of the plurality of equal areas of any smoke flue cross section where any sampling pipe layer is located is equal to the number of all sampling holes disposed on the sampling pipes of each group of sampling pipes. Each sampling pipe layer is connected with a smoke component collection and measurement unit. The device can accurately measure the processing effect of the smoke pollution treatment equipment, and monitors the operation condition of the equipment in real time.

Description

technical field [0001] The invention relates to the technical field of flue gas component measurement, in particular to a performance detection device for flue gas pollution control equipment. Background technique [0002] As my country's air pollution situation is becoming increasingly severe and air pollution prevention and control standards are becoming more and more stringent, the country's requirements for air pollution control equipment are gradually increasing. In the field of air pollution prevention and control in thermal power plants, the current common flue gas pollution control equipment includes SCR denitrification reactor, electric / bag filter, desulfurization equipment, etc. How to accurately measure the treatment effect of flue gas pollution control equipment and monitor the equipment in real time The operation situation is an important issue under the current severe situation of air pollution prevention and control. [0003] At present, the real-time monitor...
