Wireless remote diagnostics system for acoustic soot blower

The present invention relates to an acoustic suit blower wireless remote diagnosis system, and more particularly, to an acoustic suit blower wireless remote diagnosis system capable of remotely checking the sound pressure generated by an acoustic suit blower.

In general, a tube of a combustion furnace or a waste heat exchanger is a type in which a bundle of tubes (or heat transfer tubes) is repeatedly arranged. If dust or contaminants generated during combustion are accumulated on these heat exchanger tubes, thermal efficiency is lowered.

In particular, a large-scale boiler for thermal power generation using coal as a fuel generates electric energy by transferring high-temperature and high-pressure steam energy generated by burning fuel in the boiler to a turbine. In this process, as the fuel is burned in the boiler furnace, ash, a combustion ash, is generated, and the ash is melted by the high-temperature combustion heat, and the molten ash is cooled and It is adsorbed and accumulated in a soot state, and this accumulation can grow into several meters of clinker.

Since this soot interferes with the heat transfer of the tube, a soot blower for removing soot from the outer surface of the tube or the inner wall of the boiler is installed and operated periodically.

As for the soot blower, as disclosed in Korean Patent No. 10-1367641 and Korean Patent No. 10-1650735, a method of removing soot by spraying steam into the combustion structure is mainly applied.

However, the soot blower using steam has a disadvantage in that the surface of the tube is intermittently maintained clean as the tube is washed by spraying steam while the soot is already accumulated on the surface of the tube. There was a problem in that the soot removal area was narrow.

In order to solve the above problems, the present applicant uses sound waves as disclosed in Korean Patent Publication No. 10-1924607 and Korean Patent Application Laid-Open No. 10-2019-0062973 Acoustic suit for preventing the suit from being removed or accumulated Blower has been developed.

However, the structure using sound waves requires periodic inspection because the decibel or frequency changes due to the deformation of the diaphragm or wear of the horn, which vibrates by gas pressure and induces sound waves when used for a long time.

Acoustic blowers using sound waves are difficult to determine whether they are operating normally by inspecting the horns one by one when the number of installations increases. Because the cover is covered, it is difficult for the administrator to check each one.

As the gas is discharged to the diaphragm, the vortex is easily formed so that the other side in the width direction is formed at a position spaced apart in the circumferential direction with respect to the diameter line of the diffusion nozzle rather than the one side in the width direction adjacent to the center side of the gas diffusion groove. Acoustic suit blower wireless remote diagnosis system, characterized in that.
