Description

Technical Field

[0001] This utility model relates to the technical field of chemical industry, specifically to an alarm device for chemical safety management. Background Technology

[0002] Chemical engineering is an abbreviation for "chemical process", "chemical industry", "chemical engineering", etc. Any technology that uses chemical methods to change the composition or structure of substances or synthesize new substances belongs to chemical production technology, also known as chemical process. The resulting products are called chemicals or chemical products. Chemical processes are complex, involve high temperatures and pressures, and are continuous. Most materials are flammable, explosive, toxic, or hazardous chemicals. During chemical production, processing, storage, transportation, and use, toxic and harmful gases such as CO, H2S, and SO2 are often generated, leading to frequent poisoning accidents. Safety management is paramount for enterprise development; neglecting safety hazards can result in incalculable losses.

[0003] In the operation of chemical equipment, monitoring and alarm devices are usually installed to detect problems in a timely manner, such as gas leaks. However, most existing monitoring devices are fixed in one place. By the time the gas concentration exceeds the standard, the gas has already spread in the air. At this time, it is too late for the alarm device to sound an alarm, and it cannot monitor and alarm in time. Therefore, a chemical safety management alarm device is needed to improve the above problems. Utility Model Content
