Abstract

The present invention provides a remote sensing ammonia leakage monitoring and early warning device, which solves the problem in the prior art that leakage in the process of ammonia production, transportation, storage and use is difficult to quickly, highly sensitively and locate. The ammonia leakage monitoring and early warning device provided by the present invention includes: a rotating lifting platform, a TDLAS ammonia detector, a camera device, an alarm device; and an ammonia leakage monitoring and early warning device. The ammonia leakage monitoring and early warning device determines whether the ammonia concentration around the pressure equipment exceeds the standard based on the ammonia concentration distribution data. For example, when the ammonia leakage monitoring and early warning device determines that the ammonia concentration around the pressure equipment is greater than the first preset concentration based on the ammonia concentration distribution data, it generates an early warning prompt and sends the early warning prompt to the alarm device. The alarm device issues an early warning according to the early warning prompt, so that the staff near the pressure equipment can promptly discover the ammonia leak in the pressure equipment, so that the staff can repair it in time. The entire early warning process is fast and sensitive.
