Safety measures for equipment in the liquid chlorine plant

Since a toxic gas alarm is already in place, is it still necessary to install an automatic fire alarm? This post was last edited by wang*neng on 2009-3-13 11:43 ] # ， ， &
Sections involving hydrogen must take explosion prevention into account, and fire alarms must be installed throughout the entire plant.
Electrical equipment must be explosion-proof, as the greatest hazard in the liquid chlorine process is nitrogen trichloride, which is most prone to exploding under conditions of static electricity, heating, or vibration.
There are no special requirements regarding the explosion-proof nature of electrical equipment, nor is it necessary to install an automatic fire alarm system. That’s how it is with us – neither the safety nor the fire safety inspections raised any objections.
Therefore, electrical explosion protection is meaningless for nitrogen trichloride. Explosion protection is aimed at fire-prone environments, explosive gas environments, and explosive dust environments.
The electrical equipment in our company’s liquid chlorine plant is not explosion-proof; there are gas detectors in place, but no automatic fire alarm system
Our company’s safety measures mainly focus on dealing with chlorine leaks, such as spraying water after a leak occurs, as well as using fans
For liquid chlorine liquefaction plants, the structures are generally open-type; for liquid chlorine packaging plants, there is no need for explosion-proof electrical equipment. However, explosion-proof electrical devices have better corrosion resistance, so they can be considered for use. As for explosion-proof electrical equipment, it is meaningless for nitric trichloride. Safety facilities need to take into account both ventilation and sealing: ventilation is necessary so that any small leaks of chlorine can be quickly diluted and discharged, while sealing is essential in order to isolate the area in case of large chlorine leaks, thereby preventing environmental contamination. Additionally, exhaust systems and chlorine absorption devices must also be installed.
Electrical equipment in the liquid chlorine plant must be of explosion-proof type, and gas alarm devices should also be installed; automatic alarm devices are not required. For specific details, refer to the \"Safety Operating Procedures for Liquid Chlorine\"
