Hydrogen sulfide detector is a common gas detection equipment currently used in sewage treatment plants. Due to the production of toxic and flammable gases during the sewage treatment process, hydrogen sulfide gas is the main component of toxic gases in sewage treatment plants. Therefore, hydrogen sulfide detectors are installed in places where hydrogen sulfide gas is easily produced to detect the concentration of hydrogen sulfide in real time. When the concentration value exceeds the alarm limit, staff are notified to evacuate the scene and quickly take security measures. However, during the use of hydrogen sulfide detectors, some problems are inevitable, such as large display numerical errors. So what is the reason for the large numerical error displayed by the hydrogen sulfide detector?
Part of the reason for this malfunction is that the probe has not been effectively calibrated for a long time, resulting in a significant decrease in sensor sensitivity and inaccurate measurement results of hydrogen sulfide gas concentration. In addition, according to the analysis of drilling site operations, the hydrogen sulfide detector probes are mainly distributed at the wellhead, drilling floor and other locations, which makes their surface and gas explosion-proof membrane susceptible to contamination by mud and drilling fluid. In addition, the explosion-proof membrane is also easily soaked by rainwater in rainy weather. These can cause errors in the readings of hydrogen sulfide detectors.
Handling method:
1. Regularly check the usage of the probe and clean the explosion-proof membrane regularly; Regularly calibrate sensors.
2. Install rainproof devices on probes installed outdoors.
