Applications of explosive gas sensor in industrial gas leakage
In the process of using gas in industry, if the gas is in incomplete combustion state, gas leakage and so on, the gas will lead to poisoning or cause fire and explosion, which will directly threaten the safety of personnel. Therefore, it is necessary to install an industrial-grade explosive gas sensor, which can effectively detect gas leakage and issue an alarm in time to protect the safety of factories, workshops and employees. It can prevent serious fire and explosion accidents, thus reducing the huge losses caused by the accidents.
Explosive gas sensor is also known as combustible gas sensor, gas leakage detection and alarm instrument, when combustible gas leaks in industrial environment and Explosive gas sensor detects that the gas concentration reaches the critical value set by explosion or poisoning alarm, Explosive gas sensor will send out an alarm signal to remind the staff to Take safety measures. Explosive gas alarm is equivalent to automatic fire extinguisher, which can be installed to drive exhaust, cut off power, spraying and other systems to prevent explosion, fire, poisoning accidents, so as to ensure safe production. Often used in chemical plants, petroleum, gas stations, steel mills and other places prone to combustible gas leakage.
Lower Explosive Limit of Combustible Gases
When the concentration of a combustible gas exceeds the lower explosive limit, it will explode and cause injury when it encounters fire (lighters, electrical switches, static electricity, etc.). What is meant by the lower explosion limit, i.e., the lowest concentration that will explode in air when exposed to fire, and the alarm concentration is set at 1/4 or less of the lower explosion limit. For example: methane (the main component of natural gas) explosion lower limit of 50,000 ppm, propane (the main component of liquefied petroleum gas) explosion lower limit of 20,000 ppm, hydrogen (the main component of coal gas) for 40,000 ppm.
Industrial Gas
Currently common industrial gases include natural gas, liquefied petroleum gas, aromatic gases, and coal gas. All of these industrial gases have high combustion efficiencies and can meet the energy requirements of large-scale industrial production. At the same time, industrial gases often contain VOC (Volatile Organic Compounds), which are a class of compounds that are volatile at room temperature, mainly composed of carbon, hydrogen and a small amount of oxygen, nitrogen, sulfur and other elements, with a high vapor pressure and low boiling point. In industrial production, VOCs are usually generated from volatile solvents, reaction intermediates, raw materials and wastes in petrochemical, chemical, pharmaceutical, paint, printing and coating processes. After being emitted into the atmosphere, these VOCs are prone to complex chemical reactions with other pollutants such as nitrogen oxides, forming ozone precursors such as ozone and secondary organic aerosols, which may be harmful to the environment and human health. Common VOCs such as benzene, toluene, xylene, and trichloroethylene are toxic, and there are many other organic compounds in industry that may also be harmful to human health. Therefore, VOCs in industrial gases need to be given sufficient attention, and the use of TVOC Sensor can be an effective control measure to reduce their impact on the environment and human health.
