The invention provides a leakage monitoring device and system for pulverized coal conveying pipelines. Every two adjacent conveying pipelines in the pulverized coal conveying pipelines are connected through two pipeline flanges. The leakage monitoring device comprises a wrapping assembly, a first sealing ring and a flow guide recognition assembly. The wrapping assembly tightly wraps the outer sides of two adjacent pipeline flanges. The first sealing ring is arranged between the two adjacent pipeline flanges in a sealed mode, and the first sealing ring, the two adjacent pipeline flanges and the wrapping assembly define an annular cavity. The flow guide recognition assembly is provided with a monitoring cavity, the monitoring cavity communicates with the annular cavity, and the flow guide recognition assembly is provided with a photosensitive recognition element for recognizing pulverized coal in the monitoring cavity. The flow guide recognition assembly has small flow resistance to the pulverized coal, the pul
