Description

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 in the acoustic suit blower.

In general, a tube of a combustion furnace or a waste heat heat exchanger is a type in which bundles of tubes (or heat transfer tubes) are repeatedly arranged. If dust or contaminants generated during combustion accumulate in these heat exchanger tubes, thermal efficiency decreases, so it is necessary to periodically remove them or prevent dust or contaminants from accumulating.

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

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

The soot blower mainly uses a method of removing the soot by spraying steam into the combustion structure as disclosed in Korean Patent Publication No. 10-1367641 and Korean Patent Publication No. 10-1650735.

However, since the soot blower using steam cleans the tube by spraying steam while the soot is already accumulated on the surface of the tube, there is a disadvantage that the surface of the tube is intermittently maintained in a clean state, and only the part where the steam is in contact is removed. As a result, there was a problem that the soot removal area was narrow.

In order to solve the above problems, the applicant is an acoustic suit that prevents the suit from being removed or piled up using sound waves as disclosed in Korean Patent Publication No. 10-1924607 and Korean Patent Publication No. 10-2019-0062973. I have developed a blower.

However, a structure using sound waves needs periodic inspection because the decibels or frequencies change due to the deformation of the diaphragm or the wear of the horn, which vibrates by gas pressure when used for a long time and induces the generation of sound waves.

When the number of installations for acoustic blowers increases, it is difficult for the operator to check the horns to determine whether they are operating normally, and most of them are installed at high elevations or in confined places that are difficult to access, and most noise is prevented to prevent noise. Because the cover is covered, it is difficult for the manager to check each one.

Republic of Korea Patent Publication No. 10-1650735: suit blower

Further comprising a diffusion nozzle mounted at one end of the sound wave amplification induction hole facing the diaphragm to diffuse a discharge width of the gas discharged from the sound wave amplification induction hole to the diaphragm,
The diffusion nozzle
It is introduced in a circular shape in the direction of the diaphragm so as to communicate with the sound wave amplification induction hole, but the upper surface is convex downward so that the center side of the inserted upper surface is located below the edge, thereby inducing the diffusion of the gas introduced into the sound wave amplification induction hole. Gas diffusion groove,
And a plurality of vortex induction holes formed through the upper surface of the gas diffusion groove in the direction of the diaphragm at positions spaced apart from each other in the circumferential direction, and each length extending obliquely away from the center of the gas diffusion groove, and
The vortex induction hole
As the gas is discharged to the diaphragm, the eddy current 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 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.
