聲波吹灰器為什么能清灰的原因 在技術領域中，清灰技術最好的設備就是聲波吹灰器，而此設備為什么能清灰的原因，在日常的生活中很少有人能明白，那么我們今天就跟大家交流一下。主要是由于設備自身的性能價值，主要用于清灰的聲波是選用的是低頻的設備，見低頻設備具有一定強度的聲波，引入到有積灰結渣的空間，比如鍋爐煙道、熱交換器和電除塵器以及布袋除塵，而聲波針對著灰、渣起到非常高的作用，“聲致疲勞”的作用，可以理解為由于聲波震蕩的反復作用，來施加于整個設備的灰、渣以拉壓循環(huán)為變化，當達到一定的循環(huán)過程所需的應力次數時，灰渣就需要結合因疲勞而被造成破壞。同時，由于聲波自身具備著反射和折射以及繞射的自然現象，所以不管是聲源的安裝位置與方向如何，聲能量都可以進入到所有的邊角、管束間隙以及比較隱蔽的小空間的區(qū)域來有效的阻止灰塵顆粒的沉積。所我們常用的清灰措施就是蒸汽吹灰、水力吹灰以及鋼珠、高壓空氣等，都是需要設備的介質沖刷的機械力，其中最主流的吹灰技術就是聲波吹灰器。而此設備也存在著一定的缺陷，比如作用空間存在死角；用高壓值直吹受熱面，對設備有一定的磨損和腐蝕現象；結構上比較的復雜，維護量也比較的多，維護費用比較高，又不易實現有效的操控，對所有的企業(yè)常棄之不用；最后就是直吹的次數受到限制，不能夠使受熱面經常保持一定的干凈狀態(tài)，不僅會影響設備的傳熱，且不利于環(huán)保。

The reason why acoustic soot blowers can clean dust is the best equipment in the field of technology, and the reason why this equipment can clean dust is rarely understood in daily life. Therefore, we will communicate with you today. Mainly due to the performance value of the equipment itself, the sound waves mainly used for ash cleaning are low-frequency equipment. The low-frequency equipment has a certain strength of sound waves, which are introduced into spaces with accumulated ash and slag, such as boiler flue, heat exchanger, electrostatic precipitator, and bag dust removal. The sound wave needle plays a very high role in ash and slag, and the "sound induced fatigue" effect can be understood as the repeated effect of sound wave oscillation, The ash and slag applied to the entire equipment are subject to tension and compression cycles. When a certain number of stress cycles are reached, the ash and slag need to be combined to cause damage due to fatigue. At the same time, due to the natural phenomena of reflection, refraction, and diffraction of sound waves, regardless of the installation position and direction of the sound source, sound energy can enter all corners, tube bundle gaps, and relatively hidden small space areas to effectively prevent the deposition of dust particles. The commonly used cleaning measures include steam blowing, hydraulic blowing, steel balls, high-pressure air, etc., all of which require the mechanical force of equipment's medium flushing. Among them, the most mainstream blowing technology is the acoustic soot blower. And this device also has certain defects, such as dead corners in the action space; Blowing the heating surface directly with high pressure may cause certain wear and corrosion to the equipment; It is relatively complex in structure, with a large amount of maintenance, high maintenance costs, and difficult to achieve effective control, which is often abandoned by all enterprises; Finally, the frequency of direct blowing is limited, which cannot keep the heating surface in a certain clean state frequently. This not only affects the heat transfer of the equipment, but also is not conducive to environmental protection.

鍋爐吹灰器除灰內燃的技術及原理
