A combustible gas detector is composed of a sensing unit and an alarm unit.
It has wide applications in many industries, such as the petroleum industry, household gas pipelines, and chemical industry. Oil depots and other industries that may experience significant gas leaks are important instruments used to detect leaks in hazardous indoor and outdoor locations, ensuring production and personal safety. When there is a combustible gas leak in the tested area, the instrument displays the percentage concentration value of the lower explosive limit of the combustible gas. When the gas concentration exceeds this lower limit, it is prone to explosion. Therefore, the following points should be noted during use: Once the combustible gas detector is positioned in one place, it is difficult to move, so it is important to carefully consider its specific placement before placing it.
Firstly, it is necessary to identify the side leakage points of the equipment he wants to monitor, analyze the direction of the leakage, mark it, and then proceed with installation as appropriate. The density of each combustible gas is different. Combining with the flow trend of air, a three-dimensional flow chart is formed, and an initial point is set at the downstream position of the flow chart.
Then it is to study what kind of state the gas will appear when it leaks, whether it is a slight slow gas release or a spray like large gas release. If it is only a slight slow gas release, the combustible gas detector should be closer to the leak point. If it is a spray like large area of gas release, it should be farther away from the leak point, so that the concentration of gas leakage can be accurately measured. After completing the above programs, you can calculate how many combustible gas detectors need to be purchased! For places with significant combustible gas leaks, a detection point should be set up every 10-20m according to relevant regulations. For unmanned small and discontinuous pump rooms, attention should be paid to the possibility of combustible gas leakage, and a detector should generally be installed at the lower air outlet.
Finally, based on the causes of multiple accidents, it can be concluded that the failure to detect leaks of flammable gases in a timely manner was caused by incorrect installation of the combustible gas detector, resulting in the failure to take immediate measures to stop them, which led to major accidents.
