Description

Technical Field

[0001] The utility model relates to the technical field of sound waves, in particular to a sound wave generating device capable of online regulating an airway. Background Art

[0002] In the design and application of coal-fired boilers, in order to effectively remove the dust on the heating surface and make the heat transfer effect of the heating surface good, soot blowers of different forms and types are arranged on the heating surface of the boiler. Sonic soot blowers are an important part of them.

[0003] The operation effect of the sonic sootblower is directly related to its parameters. The main parameters of the sonic sootblower are: sonic frequency and sound power. The change of coal type during boiler operation and the change of equipment characteristics caused by scaling inside the boiler after a certain period of operation will cause the sootblower frequency to not match the equipment characteristics. In particular, the structure of the resonance cavity sootblower has been produced and formed, and its sonic frequency and sound power have been solidified, which cannot flexibly adapt to the changes in the characteristics of the equipment in the workplace.

[0004] The basic principle of the emerging acoustic agglomeration dust removal equipment is to use acoustic wave coupling agglomeration technology and high-efficiency cyclone separation dust removal technology to make the fine particles in the flue gas collide and agglomerate, thereby reducing the number concentration of particles and increasing the average particle size, making them easier to capture. Then, through the cyclone coupling of the high-efficiency cyclone dust collector, the large particles of fly ash are further agglomerated and coupled, which is conducive to their sedimentation and separation, and ultimately achieves the purpose of reducing the dust carried in the flue gas. Different flue gas components have different requirements for the frequency of acoustic waves.

[0005] For example, a sound wave generating device disclosed in the authorization announcement number CN208244960U includes an air intake pipe, a sound wave generator and a sound wave amplifier; the sound wave amplifier includes a trumpet-shaped sound collecting tube, the sound wave generator includes a sound tube arranged in the cavity of the sound collecting tube and a sound cavity is provided inside the sound tube, one end of the air intake pipe is connected to a compressed air generating device, and the other end passes through the sound collecting tube and is inserted into the sound cavity, and the insertion length is adjustable, and a jet hole is provided at the insertion end of the air intake pipe to facilitate compressed air to enter the sound cavity and collide with the inner wall of the sound cavity to generate sound waves, and at least one air escape hole is provided on the sound tube and / or the air intake pipe, and the sound waves are amplified by the sound collecting tube and transmitted outwardly, and the gas is discharged through the air escape hole. The utility model has a simple structure and can also generate sound waves of various frequencies to optimize the dust removal effect. However, the utility model lacks an online adjustable mechanism, which is not convenient for online regulation of the airway. To this end, we propose an acoustic wave generating device that can adjust the airway online, which solves the real-time online adjustment problem of the device and effectively prevents the risk of equipment failure due to airway wear during operation, thereby improving the practicability and economic benefits of the device.
