摘要： A boiler ash remover based on a combined flow includes a frequency-adjustable acoustic flow generator, a fixing bracket, a compressed air source, a three-way air-source electric-control valve, an air jet generator, an acoustic-jet combined transmission tube, an acoustic jet intelligent control system, and a scale measurement and control sensor. The compressed air source is connected to an inlet end of the three-way air-source electric-control valve. An outlet end of the three-way air-source electric-control valve is connected to the frequency-adjustable acoustic flow generator and an air source inlet end of the air jet generator respectively. An acoustic flow outlet end of the frequency-adjustable acoustic flow generator is connected to an inlet end of the acoustic-jet combined transmission tube. An outlet end of the acoustic-jet combined transmission tube and a jet outlet end of the air jet generator are both disposed opposite to an external heat exchange component by means of the fixing bracket. The area of an acoustic flow transmission orifice at the outlet end of the acoustic-jet combined transmission tube covers that of a jet injection orifice at the jet outlet end of the air jet generator. The acoustic jet intelligent control system is connected to an electric control device of the three-way air-source electric-control valve and the scale measurement and control sensor respectively. The scale measurement and control sensor is disposed on the external heat exchange component. The boiler ash remover has the advantages of combining a frequency-adjustable acoustic flow with an air jet and implementing acoustic jet intelligent control, and has a desirable effect of removal of scales in a hearth or a flue gas heat exchanger.

摘要： Disclosed is a sound absorption plate with a unit structure. The sound absorption plate comprises an ultramicropore sound absorption front plate (1), a side plate (2) and a sound absorption back plate (3). Edge parts of the ultramicropore sound absorption front plate (1) are connected to the sound absorption back plate (3) through the side plate (2), thereby forming a sound absorption resonant cavity (4). The material of the ultramicropore sound absorption front plate (1) is a metal material carrying nano microspheres (5). A sound absorption metal thin film (6) carrying nano microspheres (5), parallel to the ultramicropore sound absorption front plate, is disposed inside the sound absorption resonant cavity (4). A pore size of the nano microspheres in the ultramicropore sound absorption front plate (1) and the sound absorption metal thin film (6) is 100-1000 nm. The sound absorption plate has a simple structure, simple and convenient manufacture and assembly, a wide sound absorption frequency band and a good noise reduction effect, and is suitable for ceiling and wall decoration of buildings.
