Hydrogen sulfide detectors are widely used in petroleum and petrochemical companies, and play a very important role in preventing poisoning accidents and reducing casualties. The hydrogen sulfide detector is an important monitoring instrument for safe production. Its main function is to detect the concentration of hydrogen sulfide gas in the air. When the concentration in the air reaches a certain concentration, the hydrogen sulfide detector will automatically sound and light alarm to remind The staff shall take corresponding measures in time to avoid the occurrence of major accidents. We must be proficient in the use of hydrogen sulfide detection and alarm devices. Aiyi Technology takes everyone to pay attention to relevant precautions when understanding hydrogen sulfide detection and alarm devices.

The drilling site, downhole operation site, gathering and transportation station, natural gas purification plant, water treatment station and refining equipment area where hydrogen sulfide gas is easy to release and accumulate should be installed with hydrogen sulfide gas detection alarm. The specific installation location of the detector should be determined according to the field equipment and facilities, process equipment, and the diffusion and accumulation of hydrogen sulfide gas. As the hydrogen sulfide gas is heavier than air, the hydrogen sulfide detector should be installed below the release source. The distance from the release source outside the room is no more than 2m, and the indoor distance is no more than 1m. It is best to be 0.5m near the release source and the installation height should be higher than the ground (or Floor surface) 0.3-0.6m. The detector is too low, and it is easy to be splashed by rain and cause damage to the detector. If conditions permit, try to use a detector with concentration display and sound and light alarm, so that the operator does not need to go back to the duty room to check the alarm controller, and the presence of hydrogen sulfide gas can be observed at the operation site to better protect personal safety .

  1. Pay attention to the detection interference between various sensors

Generally speaking, each type of sensor corresponds to a specific detection gas, but it is impossible for any type of gas detector to be special. Therefore, when choosing a gas sensor, you should know as much as possible about the detection interference of other gases on the sensor to ensure its accurate detection of specific gases.

  1. Pay attention to the concentration measurement range of the testing instrument

All kinds of harmful gas detectors have their fixed detection ranges. Only when the measurement is completed within its measuring range, can the instrument accurately measure. However, measuring beyond the measuring range for a long time may cause sexual damage to the sensor.

  1. Improve the accuracy of the gas detector

The gas detector needs to be re-calibrated after a long time of use. At the same time, due to various improper use methods during use, the measurement accuracy of the gas detector will be greatly reduced, and it will be a very careful measure to improve the measurement accuracy of the gas detector. Work needs to be adjusted in many aspects, so as to ensure the accuracy of the gas detector.
