China has become the world's first major producer of chemicals, the petrochemical and chemical industry is a pillar industry of the national economy, with a large economic volume, a long industrial chain, a wide range of products, and a wide range of related coverage, which is related to the safety and stability of the industrial chain supply chain, green low-carbon development, and improvement of people's well-being. There are many types of chemical products, and the transportation and storage of a considerable part of hazardous chemicals is a key area of concern. Despite the complete safety awareness and preventive measures, the annual occurrence of hazardous chemical logistics accidents is high, and the safety situation of hazardous chemical logistics is still not optimistic. Although the accident rate of hazardous chemical logistics has the characteristic of "low probability", but the consequences of the accident have the nature of "high risk". Once an accident occurs in the process of transportation, loading and unloading, storage, it will pose a huge threat to the safety of people's lives and property and public safety in the vicinity of the accident, affecting social stability and high-quality economic development.

Challenge

Monitoring temperature and humidity is the top priority for the safety management of chemicals, especially dangerous chemicals warehouses. According to the "Opening Conditions and Technical Requirements for Hazardous Chemicals Business Enterprises", all kinds of dangerous chemicals should be stored within the appropriate temperature and humidity according to their nature. Explosive goods, oxidizers, compressed and liquefied gases, spontaneous combustion goods, moisture-proof goods, flammable liquids, flammable solids, toxic goods and corrosive goods have strict and different regulations for temperature, humidity and ventilation, which require very high requirements for real-time management of storage. Most of the chemicals are sensitive to humidity, powders, crystals, concentrated solutions, etc. Most of the chemicals are sensitive to humidity, and although many of them are subject to sealing treatment such as wax sealing, the actual warehouse still needs to pay attention to humidity monitoring and surveillance. On the temperature factor, the higher the ambient temperature, the faster the volatility of the liquid, which may lead to the content of flammable substances in the air may reach dangerous values and increased risk. Even if it is not easy to volatile solid hazardous materials, the rise in ambient temperature will make the molecules more active, oxidation and other chemical reactions to speed up, itself and release heat, such as unfavorable conduction will cause heat buildup, so that the reaction further intensified, forming a vicious circle until out of control. Even some flammable raw materials with low ignition point, the temperature rises slightly to easily reach the ignition point. And the temperature is too low can also lead to problems, such as methyl polyethylene glycol and other chemicals in the insulation warehouse storage, if the temperature is too low, will appear turbid deterioration crystallization and other problems, causing higher cargo loss; in the humidity factor, most solid hazardous chemicals, powder and other quality directly affected by humidity, may appear slab and other conditions. In addition, the storage of certain flammable and explosive chemicals has high requirements for explosion-proof, and the electronic equipment used for monitoring needs to have the qualification of explosion-proof. The management of numerous categories and high dangers requires extremely high timeliness, and the monitoring of key temperature, humidity, ventilation and gas leakage is of the utmost importance. The requirements for enterprises as well as warehouse personnel are relatively high.

Solution

Humpback Whale's chemical customers are among the world's top 500, with a complete safety management system and advanced ideas for chemical warehouse storage, Humpback Whale cooperates with users to manage the temperature and humidity of chemical warehouses, providing strong support for customers to supervise the safe storage of chemicals more reasonably and effectively, and reduce the safety risks of dangerous logistics and loss of goods. humidity. The LoRa gateway is equipped with various types of probes, which can detect temperature and humidity at multiple points in the warehouse. In actual operation, the chemical warehouse carries out refined zoning temperature and humidity monitoring, and sets temperature and humidity thresholds in accordance with the nature of chemicals stored in each warehouse and each area, and carries out real-time over-threshold alarm and power-off alarm by means of WeChat, SMS and management platform, and specifies multiple alarm objects and multi-level alarm objects to ensure that environmental information such as warehouse temperature and humidity can be quickly, truly, effectively and timely This ensures that the environmental information such as temperature and humidity of the warehouse can be quickly, truly, effectively and timely notified to the site manager and extended to the person in charge at all levels according to the settings to ensure the quality and safety of the chemicals stored in the warehouse. The humpback whale products used in this case include but not limited to LoRa gateway, LoRa visual gateway, built-in temperature and humidity probe, external temperature probe, explosion-proof probe, etc.
