Carbon dioxide sensor and sulfur dioxide sensor can be used for multiple gas detection in tunnel construction
With the development of science and technology, in order to meet the needs of people's lives and stimulate the growth of the national economy, more and more tunnel operations have become important projects in the project. Tunnel work is an industrial field with a relatively high risk factor, because there will be some toxic and harmful gases in the tunnel during tunnel work, which will endanger the personal health of the worker.
In nature, the decay of organic matter will produce hydrogen sulfide and combustible gas, which are stored in large quantities in the formation. Especially in mountainous areas, after thousands of years and countless crustal movements, the geological conditions are even more special. Countless toxic gases such as carbon monoxide, carbon dioxide, and hydrogen sulfide hide in rocks like balloons. Once these gases are touched during tunnel construction, they will spread immediately, and the concentration will soar instantly. Combustible gases will explode when they encounter an open flame, posing a serious threat to the lives of construction workers.
In order to ensure the smooth progress of tunnel construction and the personal safety of construction workers, the "Nine Regulations on Tunnel Construction Safety" clearly stipulates that "toxic and harmful gases must be monitored, ventilation management must be strengthened, construction with concentrations exceeding the standard is strictly prohibited, and tunnel gas detectors must be installed." And due to the poor ventilation conditions during tunnel construction and excavation, it is necessary to install a professional gas detector during tunnel construction to monitor the gas changes inside the tunnel, to prevent the danger caused by excessive harmful gas during tunnel construction, and to ensure the safety of personnel and construction personnel. Safety.
The gas detector is an instrument used to detect gas composition and concentration. There are many sensor detection components inside, such as hydrogen sulfide sensor, carbon monoxide sensor, carbon dioxide sensor, oxygen sensor, combustible gas sensor, etc. Gongcai.com acts as an agent for gas sensors that can be used for gas detection in tunnels, such as the following:
American SPEC Sensors SO2 sulfur dioxide sensor - 3SP-SO2-20, ultra-thin printed sensor is easy to integrate into wireless, handheld and other network solutions. Due to their high performance, low cost and small size, these sensors are ideal for health, environmental, industrial and residential monitoring.
In addition to preventing common toxic and harmful gases, it is also necessary to do a good job of ventilation in the tunnel to ensure that once the toxic and harmful gases are generated, they can diffuse out as soon as possible and reduce the concentration of toxic and harmful gases in the tunnel. In addition, we need to know that different tunnels contain different kinds of harmful gases, so users can take preventive measures according to their actual needs.
