Background
With the rapid development of chemical industry, the types of flammable, explosive, toxic and harmful gases are increased, and timely acquisition of the content of target gases in air is very important for avoiding explosion and poisoning accidents. Therefore, various gas detectors are widely applied to environmental monitoring, and whether the quantity value is accurate or not is related to the life and property safety of people.
The metering mode of the gas detector mainly has two types: off-line metering and on-line metering. And (4) off-line metering, namely disassembling the gas detector and metering in a laboratory. This approach has the following two disadvantages: firstly, there is complicated coupling relation usually between gas detection appearance and the apparatus for producing, dismantles the in-process and carelessly neglects a bit, just can cause production facility to stop the operation, causes irreversible loss, and the operating mode that gas detection appearance used, the environment is complicated, and the work degree of difficulty of dismantlement is high, intensity is big. Secondly, if the gas detector is dismantled, the leakage condition of poisonous, harmful, inflammable and explosive gas in the production field cannot be known in time, and huge potential safety hazards exist. Therefore, online gas detectors for monitoring production environments mostly adopt online metering.
The traditional on-line metering mode needs one metering person to enter a gas standard substance to the installation position of a gas detector, and the other metering person observes an indication value and an alarm condition at one end of an alarm controller. This approach has the following three disadvantages: firstly, in the field of chemical industry, steel and other factories, the installation positions of some gas detectors are high, and the high-altitude operation of metering personnel has certain dangerousness. Sometimes, the target instrument cannot be touched due to the fact that the overhead ladder and the lift car are placed everywhere and are shielded by a pipeline; secondly, a gas metering detector usually needs 3 concentration values of gas standard substances, and one worker cannot carry the gas standard substances at the same time, so that the verification efficiency is low; thirdly, the gas detector for measuring each range needs a gas standard substance with a matched concentration value, and the commercially available gas standard substance cannot cover all concentrations, so that some gas detectors cannot measure the gas and potential safety hazards are left.
Therefore, it is necessary to design an on-line metering device to improve the metering efficiency and the metering coverage rate of the gas detector, ensure the accurate and reliable measurement value of the gas detector, and further ensure the production safety.
