Liquid ammonia is generally used as a refrigerant in cold storage. If a leak occurs, it may cause harm to personnel and the environment. Ammonia is a toxic gas with strong irritation and corrosiveness, which has a great impact on human health and the ecological environment.
The main reasons for ammonia leakage in cold storage include:
Equipment aging: With the increase of use time, cold storage equipment such as valves, welds, flange gaskets, etc. may age, such as valve axis loosening, weld aging, flange gasket aging, etc., resulting in decreased air tightness, which in turn causes ammonia leakage.
Personnel operation error: Illegal operation by staff is also one of the important reasons for ammonia leakage. For example, improper operation may cause liquid ammonia or equipment oil to enter the compressor cylinder, causing excessive pressure in the cylinder, and then causing a leakage accident.
Management negligence: The lack of strengthened operation management, weak technical strength and negligence of operating workers are also one of the reasons for ammonia liquid leakage.
In order to solve the above problems, it is necessary to install ammonia detection alarms at key locations, such as cold storage liquid ammonia storage tank areas, refrigeration equipment assembly workshops, loading and unloading sites, and ammonia transmission pipelines. These instruments can sensitively detect the concentration of ammonia, and immediately sound and light alarms when the concentration reaches or exceeds the preset alarm value.
The ammonia leak detection alarm can monitor the ammonia concentration in the cold storage in real time. Once the concentration exceeds the standard, an alarm will be issued immediately to remind personnel to take corresponding measures to prevent accidents. This is very important for ensuring personnel safety and the normal operation of the enterprise. The role of the ammonia leak detection alarm is not limited to alarms, but can also be linked to other equipment, such as exhaust fans, solenoid valves, etc., to promptly remove leaked ammonia and prevent it from causing further damage to the environment and equipment.
In addition to the ammonia leak detection alarm, it is also necessary to conduct regular safety inspections and maintenance of the cold storage to ensure the normal operation of the equipment and reduce the risk of ammonia leakage. At the same time, it is also very necessary to strengthen employee safety training and education and improve employee safety awareness and emergency response capabilities.
To sum up, installing wall mounted ammonia gas detector in a cold storage is an important measure to ensure the safe operation of the cold storage. It can effectively prevent poisoning accidents and explosions and protect human life and property safety.
