Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of chemical product sealed storage tank, especially to a sealed storage tank for chemical product storage and transportation. BACKGROUND

[0002] Under the background of rapid development of global chemical industry, the storage and transportation of chemical products have become the key link to ensure the stable operation of the industrial chain. According to statistics, only the chemical raw materials and products transported by storage tanks in China each year exceed hundreds of millions of tons, covering petroleum chemical industry, fine chemical industry, pharmaceutical chemical industry and other fields. Most of these chemical products have dangerous characteristics such as flammability, explosiveness, strong corrosiveness or toxicity. Once leakage or reaction out of control occurs during storage and transportation, it will cause serious safety accidents and environmental pollution problems.

[0003] However, most of the sealed storage tanks for chemical product storage and transportation on the market have significant defects in pressure control. Many storage tanks still rely on manual inspection and simple pressure gauge to monitor pressure, and cannot real-time and accurately grasp the dynamic changes of the pressure in the tank. Once the pressure is abnormal, the operator is difficult to detect in time, and it is also impossible to take effective pressure relief measures in a short time. Although some storage tanks are equipped with pressure monitoring devices, they lack automatic pressure relief structure. When the pressure exceeds the safety threshold, only manual operation of the valve can be used to relieve pressure. This way not only has slow response speed, but also in emergency situations, the operator may face great safety risks, making it difficult to ensure the accuracy and timeliness of the operation.
