Technical Field

[0001] The utility model relates to the field of flue soot blowing equipment, in particular to a denitrification flue soot blowing device. Background Art

[0002] The flue gas generated by the combustion of coal in a coal-fired boiler usually contains nitrate oxides, which need to be introduced into a denitrification device through a denitrification flue for denitrification.

[0003] After a long period of use, a large amount of dust will accumulate inside the denitrification flue. The accumulation of a large amount of dust seriously affects the circulation of flue gas inside the flue. In order to ensure smooth flue gas circulation, it is necessary to regularly blow soot inside the flue. Therefore, it is necessary to design a denitrification flue soot blowing device.

[0006] Furthermore, the right end of the mounting plate is fixedly connected to a fixing frame, the interior of the fixing frame is fixedly connected to a motor, the output shaft end of the motor is fixedly connected to a driving wheel, the circumferential surface of the rotating conveying tube is fixedly connected to a driven wheel, and the driving wheel and the driven wheel are connected by a belt.

[0007] Furthermore, an annular support seat is fixedly connected to the inner wall of the mounting plate, an annular rotating seat is fixedly connected to the right end of the diversion hollow plate, and the annular rotating seat is located inside the annular support seat and is rotatably connected to the annular support seat.

[0008] Furthermore, there are multiple first connecting tubes, which are evenly located at the left end of the diverter hollow plate, and the multiple first connecting tubes are interconnected with the diverter hollow plate. Multiple blowing heads are fixedly installed on the circumferential surfaces of the multiple first connecting tubes, and the multiple blowing heads are gradually inclined away from the first connecting tubes.

[0011] The utility model has the following beneficial effects:

[0012] Compared with the prior art, the denitrification flue soot blowing device installs the mounting plate in the denitrification flue and then controls the sound wave generator to work. The generated sound waves will enter the annular diversion cylinder along the transmission pipe and then be ejected from the nozzle along the second connecting pipe. The ejected sound wave energy acts on the denitrification flue. The force of the sound waves can cause the dust particles and air molecules to oscillate, so that the dust particles are in a suspended fluidized state, effectively reducing the condensation of the dust particles so that the flue gas can carry them away. At the same time, the fan is controlled to operate, and the generated wind will enter the diversion hollow plate along the fixed pipe and the rotating transmission pipe, and finally enter the first connecting pipe and be ejected from the blowing head. The ejected gas blows toward the inner wall of the denitrification flue, thereby accelerating the detachment of dust attached to the inner wall of the denitrification flue, thereby effectively improving the soot blowing efficiency of the denitrification flue.
