Acetylene C2H2 is a colorless and highly flammable gas at room temperature, so it is necessary to configure an acetylene alarm in the use of acetylene, and monitor the on-site concentration value of acetylene 24 hours to ensure safe production.
Acetylene gas alarm is composed of gas detector and gas alarm controller, gas detector installed in the gas leak detection site, through the core component gas sensor, to achieve real-time detection of gas concentration, can also work independently. The gas alarm controller can be placed in the duty room, receive the concentration detected by the gas detector, and realize the concentration display and audible and visual alarm function after the concentration exceeds the standard, and can link external equipment (such as solenoid valve, exhaust fan, spray device) to upload PLC, DCS, fire protection system, etc.
The acetylene leak alarm belongs to one kind of flammable gas alarm, and the setting value of the alarm point is less than or equal to the lower explosive limit of 25%; Acetylene leak alarm level 2 alarm set value less than or equal to 50% lower explosive limit.
During the use of C2H2 combustible gas monitor, More attention should also be paid to preventing electromagnetic interference. The installation position, installation Angle, protective measures and system wiring of the adjustable alarm should be prevented from electromagnetic interference. In the process of using the acetylene gas detector, users should pay more attention to the environment factors that are easy to cause breakdown, such as: dust, high temperature, humidity, rain, etc.
When an exhaust fan is installed in the place near the acetylene gas detector. the leaking gas will not be able to fully spread to the vicinity of the combustible alarm, resulting in timely detection and easy error. Note: The use of combustible gas detector also needs to pay attention to avoid high temperature, high humidity, steam, smoke to the place, which will reduce the service life of the instrument, easy to false alarms.
Acetylene C2H2 density is lighter than air, with a molecular mass of 29 for air and 26 for C2H2. Acetylene is lighter than air, and the acetylene detector should be installed at a distance of 30 to 60 cm from the ceiling, and the sensor position is downward.
The fixed acetylene gas detector is a best choice for company that rely on acetylene gas in their daily operations. It not only helps to protect workers from workplace hazards but also ensures the continuity of production by preventing costly shutdowns due to gas leaks.
