The utility model relates to the technical field of soot blowers, and discloses a boiler soot blower which comprises a boiler shell and an ultrasonic generation assembly fixedly installed on the outer side of the boiler shell through a supporting seat, a loudspeaker is rotatably installed on the inner side of the boiler shell through a hinged support, a connecting base is fixedly installed on the inner side of the boiler shell, and the connecting base is fixedly connected with the ultrasonic generation assembly. The inner side of the connecting base is rotationally connected with a threaded transmission rod through a transmission assembly, the periphery of the threaded transmission rod is connected with an adjusting rod in a threaded fit mode, the top of the adjusting rod penetrates through a limiting shell at the top end of the connecting base and is slidably connected with the inner side of the limiting shell, and the top end of the adjusting rod is hinged to the bottom of a loudspeaker through a sliding assembly. A pipeline installer is fixedly installed in the boiler shell, and one end of the pipeline installer communicates with the ultrasonic generation assembly. The boiler soot blower has the advantages that the angle of the soot blowing pipe can be changed, and the overall soot blowing effect of the boiler soot blower is improved.

The application discloses a rotary air preheater with a multilayer annular heat pipe, relates to the technical field of air preheating, and comprises an outer shell, an inner rotor, a center cylinder, a flue gas inlet, an air outlet, a flue gas outlet, an air inlet, a disturbance mechanism, a ring pipe group, a driving piece and a corrugated plate group. The center cylinder is coaxially arranged at the center position in the outer shell, the inner rotor is rotationally arranged on the outer wall of the center cylinder, the outer wall of the inner rotor is rotationally connected with the inner wall of the outer shell, the inner rotor is driven by the driving piece located at one side of the outer shell, the flue gas inlet and the air outlet are formed in the top end of the outer shell, and the flue gas outlet and the air inlet are formed in the bottom end of the outer shell. The corrugated plate group and the ring pipe group are arranged in the inner rotor, and a plurality of disturbance mechanisms are circumferentially arranged on the inner wall of the ring pipe group. The flue gas and the air are transversely washed to the annular heat pipe, the heat exchange coefficient of the flue gas and the air is strengthened, the deposition rate and deposition amount of ammonium bisulfate on the heated surface can be significantly slowed down, and the safety risk is reduced.

The application provides a negative pressure suction adaptive dust removal system, which specifically comprises a gravity dust remover, a cyclone dust removal device, an air cooler, a bag dust remover, a centrifugal multi-stage induced draft fan and a control system; the gravity dust remover removes larger particles in ash gas by using gravity to achieve primary dust removal; the cyclone dust removal device is connected with the gravity dust remover through a pipeline and removes the ash gas by using centrifugal force to achieve secondary dust removal; the air cooler cools high-temperature gas discharged from the cyclone dust removal device to avoid burning the bag in the subsequent process; the bag dust remover realizes third-stage dust removal through the filtering effect of the bag to make the ash gas meet the emission standard; the centrifugal multi-stage induced draft fan is arranged at the end of the system to generate negative pressure to drive the flow of the ash gas; the control system monitors the running state of the system in real time through a temperature sensor, a pressure sensor and a level meter and sends out an alarm or performs adaptive dust removal; and the application realizes efficient dust removal of the ash gas and real-time monitoring and adaptive adjustment of the dust removal process.

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.
