Uniformly-distributed liquid dripping and spraying device

The invention provides a uniformly-distributed liquid dripping device, which adopts a dripping liquid distribution mode of a multi-layer partition flow guide structure and a sawtooth dripping plate, and consists of a liquid collecting pipe group, an upper disc, a longitudinal lower disc and a transverse lower disc, wherein the liquid collecting pipe group and the upper disc form a closed dripping and spraying structure, the longitudinal lower disc and the transverse lower disc form a combined lower disc, the combination adopts a mode of combining an open partitioned liquid storage structure and a closed partitioned distribution dripping and spraying structure, and a liquid guide structure is adopted between the upper disc and the lower disc. According to the device designed by the invention, the liquid can be uniformly distributed and uniformly dripped on the heat transfer pipe, so that the reduction of the heat exchange performance of the unit is avoided, the lithium bromide absorption unit can still normall
