Result cannot find this operation problem in time.
And as this reactor installs gas pollution control equipment performance of the present utility model detection device, importing and exporting respectively
Arranging upper, middle and lower three level sampling pipeline, arrangement is as in figure 2 it is shown, smoke components measurement result is as shown in table 5:
Table 5 SCR denitration reactor measurement result running status is assessed
From above smoke components measurement result it can be seen that SCR denitration reactor corresponding to the sampling line of middle level de-
Nitre efficiency substantially reduces, and operation problem occurs.It is to say, break down or problem in the middle part of SCR denitration reactor, inspection
Fault can quickly be investigated by the personnel accordingly of repairing.As can be seen here, pollutant handling arrangement described in the utility model is utilized
Energy evaluation methodology, can judge the running status of pollutant handling arrangement fast and effectively, and be accurately positioned its fault zone.
From two above specific embodiment it can be seen that gas pollution control equipment performance of the present utility model detection fills
Put, both the overall performance of pollutant handling arrangement can be monitored in real time, understand its overall operation situation, it is also possible to pass through
The measurement result of comparison difference sampling layer, the ruuning situation of monitoring pollution thing processing means respective regions, find pollutant in time
The operation problem of processing means and the accurate location at problem place, provide convenience for day-to-day operation monitoring and Maintenance and Repair.
Finally, it should be noted that, illustrate as a example by above-described embodiment three level sampling pipe the most, it practice, according to flue
Cross-sectional sizes or actual demand, can arrange the probe tube number of plies is two-layer, and corresponding flue cross section is also configured as two points
District；Equally arranging the probe tube of more than three layers, corresponding flue cross section is also configured as divide corresponding with the probe tube number of plies
District.
