Gas Detection Applications
Which gas detectors are required by the tire plant? Which scenarios are these detectors applicable? How should the gas detector be chosen according to different usages?
Gases which are detrimental to the human health, such as benzene, methylbenzene, xylene, and VOC gases, are detected on the work site. The combustible gases should have their combustibility detected to prevent occurrence of explosions. For example, the warehouse and the tank storage area should detect the gas combustibility. It is also necessary to detect whether the detected gases have exceeded the standard, such as detection of VOC.
Model selection: The gas detector is either fixed or portable. The toxic gas detector's range is between 0 ppm and 100 ppm or below 0-1,000 ppm. The higher the toxicity is, the smaller the range is. The range of combustible gases is usually between 0 LEL and 100% LEL. As to the gas concentration discharged by the chimney into the air, the range of 0 ppm to 2,000 ppm is adopted.
The pharmaceutical plant usually chooses the oxygen and ozone gas detector. The oxygen gas detector can detect the purity; the ozone gas detector can measure the disinfection concentration and the residual ozone concentration after disinfection. Either the fixed gas detector or the portable gas detector can be adopted. The fixed one can be installed in the return air duct for detection or installed in the disinfection workshop.
The toxic gas detector (such as the formaldehyde and VOC) can be used to detect volatilization of the finished products for the purpose of reaching the national standards of protecting personal safety. The spray workshop can adopt the combustible gas detector to prevent occurrence of the explosion. Either the fixed gas detector or the portable gas detector can be adopted.
If the gas detector is used to detect the toxicity (for personal health), the gas detector with the range of 0 to 10 ppm should be chosen for formaldehyde; the gas detector with the range of 0 to 10 ppm should be chosen for VOC, the gas detector of the 0-100% LEL should be chosen for the combustible gas, and the gas detector with the range of 0 to 2,000 ppm should be chosen for VOC.
The toxic gas detector, combustible gas detector, and oxygen gas detector can be used to prevent leakage of ammonia or lack of oxygen.
For the nitrogen or acetylene storage workshop, and the chemical storage workshop, the combustible gas detector can be adopted.
For the livestock farm, the toxic gas detector (such as ammonia gas, NH3, and sulfuretted hydrogen, H2S) can be adopted for the purpose of poisoning prevention. The fixed gas detector and the portable gas detector are both acceptable. The sufurretted hydrogen can prevent poisoning, and detection of the ammonia gas is to guard against an excessive concentration of ammonia gas to influence the livestock’s health.
