Fixed Hydrogen Cyanide (HCN) Gas Detector Dimension (Unit: mm)
SISCO Gas Detector Catalogue.pdfQ1: What is a fixed gas detector?
A1: The fixed gas detector is composed of sensors and transmitters, and is installed at the detection site. The secondary instrument consisting of circuit, power supply and display and alarm device is installed in a safe place, which is convenient for staff to monitor. In industrial installations and production processes, fixed gas detectors are generally used, because fixed gas detectors can be installed at specific detection points to detect specific gas leaks.
Q2: What does a gas detector detect?
A2: Combustible gases: Natural gas (methane), liquefied gas, coal gas (hydrogen), acetylene, pentane, alkynes, acetone, toluene, alcohols, hydrocarbons, light oil, etc.
Toxic gases: Carbon monoxide, hydrogen sulfide, ammonia, chlorine, oxygen, phosphine, sulfur dioxide, hydrogen chloride, chlorine dioxide and other toxic and harmful gases.
Q3: Difference between fixed gas detector and portable gas detector
A3: The biggest advantage of fixed gas detectors is 24-hour uninterrupted measurement. As long as the power is turned on, the fixed gas detector is in normal detection work. Portable gas detectors are usually used in confined spaces and confined spaces, but the gas environment in these spaces is usually very complex, and there will be situations such as lack of oxygen and high concentrations of harmful gases.
Tips: Why do you need to detect hydrogen cyanide with HCN gas detector?
Hydrogen cyanide is mainly used in electroplating, mining, ship cabins and warehouses for smoking and rodent control, manufacturing various resin monomers such as acrylic resin, methacrylic resin and other industries. In addition, it can also be used in the production process of cyanide.
Hydrogen cyanide is liquid in its standard state. Hydrogen cyanide is easy to disperse evenly in the air and can be combusted in the air. When the content of hydrogen cyanide in the air reaches 5.6% to 12.8%, it is explosive. Highly toxic and deadly, colorless and bitter, with an almond odor, it boils at 26°C (79°F), just above room temperature.
According to the Comprehensive Emission Standard of Air Pollutants, the maximum emission concentration of HCN gas is 1.9mg/m3, which is 1.79ppm. The maximum allowable concentration in the air is 0.3mg/m3, which is 0.27ppm. Hydrogen cyanide inhalation can inhibit respiratory enzymes and cause intracellular asphyxia. The lethal dose is 1mg/kg (body weight). Inhalation of high concentrations of hydrogen cyanide gas in a short period of time can cause death by immediate respiratory arrest.
Non-sudden death is clinically divided into 4 stages: mucosal irritation, accelerated and deepened breathing, fatigue, headache in prodromal stage; tongue tip and oral numbness in oral administration. The dyspnea period includes dyspnea, elevated blood pressure, bright red skin and mucous membranes, etc. Convulsions, coma, and respiratory failure occur during convulsions. During paralysis, the muscles of the whole body relax, and the breathing and heartbeat stop and die. It can cause eye and skin burns and cause poisoning when absorbed. Therefore, it is very necessary to use a hydrogen cyanide gas detector to detect HCN.
