The utility model relates to a kind of ammonia water spraying devices of denitration system, including pressure pump, ammonia water collection unit, flue gas conveying pipe, ammonia water primary atomization unit, ammonia water secondary atomization unit, pressure pump is installed in the air inlet shell outside of denitration system, and air inlet shell is inverted L shape, ammonia water primary atomization unit is set in the upper portion in air inlet shell and is connected with pressure pump, ammonia water collection unit is set in ammonia water primary atomization unit below, for collecting the redundant ammonia water that ammonia water primary atomization unit sprays, ammonia water secondary atomization unit is set on ammonia water collection unit, for the redundant ammonia water collected is atomized again.The utility model can collect the redundant ammonia water that sprays, and under the action of ammonia water secondary atomization unit, the ammonia water collected is atomized, not only can avoid ammonia water waste, ammonia water spraying can be increased, effectively improve ammonia water and flue gas mixing, more efficiently carry out denitration.

The invention relates to the technical field of ecological restoration, and provides a side slope ecological restoration hanging net spray-seeding device which comprises a shell, a material conveying pipe, a material uniformizing swing mechanism and a lifting material shaking mechanism. The conveying pipe is connected with a spray head; the material uniformizing swing mechanism comprises a driving device, a transmission assembly, a swing assembly and an execution connecting piece, the output end of the driving device is connected with the transmission assembly, the transmission assembly is in transmission connection with the swing assembly, the swing assembly is in sliding and circumferential limiting connection with the execution connecting piece, and the bottom of the execution connecting piece is connected with the spray head; the lifting and shaking mechanism comprises a linkage assembly, the linkage assembly is in transmission connection with the transmission assembly, and the output end of the linkage assembly is rotationally connected with the top of the execution connecting piece so as to drive the spray head to vertically ascend, descend and shake in a reciprocating mode under driving of the driving device. Through the joint arrangement of the material uniformizing and swinging mechanism and the lifting and shaking mechanism, synchronous swinging and shaking operation of the spray head is achieved, and the material spraying uniformity and the material spraying efficiency can be further improved.

The invention discloses a spraying device for soot blowing of a power plant boiler, and belongs to the technical field of soot blowing spraying devices, the spraying device comprises a soot blower, a connecting pipe is fixedly arranged at the air outlet end of the soot blower, the spraying device further comprises an adjusting pipe and a spraying pipe, the adjusting pipe is rotationally arranged in the connecting pipe, and the spraying pipe is fixedly arranged at the front end of the adjusting pipe; and a plurality of sets of spraying heads are fixedly arranged on the outer wall of the spraying pipe and distributed in a transverse array mode, and a lifting mechanism is arranged at the top of the connecting pipe in a penetrating mode and used for driving the spraying pipe to do lifting motion. The transmission mechanism can drive the adjusting pipe to rotate around the axis of the adjusting pipe, when the adjusting pipe rotates, the spraying pipe fixed to the front end of the adjusting pipe and the spraying head synchronously rotate along with the adjusting pipe, a lifting and rotating composite motion track is formed, efficient and uniform covering of boiler soot blowing spraying is achieved, and the accumulated soot removing efficiency is remarkably improved.
