聲波吹灰器為什么能清灰的原因 在技術(shù)領(lǐng)域中，清灰技術(shù)最好的設(shè)備就是聲波吹灰器，而此設(shè)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(shè)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(shè)備，見低頻設(shè)備具有一定強(qiáng)度的聲波，引入到有積灰結(jié)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(fù)作用，來施加于整個設(shè)備的灰、渣以拉壓循環(huán)為變化，當(dāng)達(dá)到一定的循環(huán)過程所需的應(yīng)力次數(shù)時，灰渣就需要結(jié)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(xiàn)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(jìn)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(shè)備的介質(zhì)沖刷的機(jī)械力，其中最主流的吹灰技術(shù)就是聲波吹灰器。而此設(shè)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(shè)備有一定的磨損和腐蝕現(xiàn)象；結(jié)構(gòu)上比較的復(fù)雜，維護(hù)量也比較的多，維護(hù)費(fèi)用比較高，又不易實現(xiàn)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(shù)受到限制，不能夠使受熱面經(jīng)常保持一定的干凈狀態(tài)，不僅會影響設(shè)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(nèi)燃的技術(shù)及原理

在技術(shù)領(lǐng)域的支持下，總結(jié)出鍋爐吹灰器除灰內(nèi)燃的技術(shù)及原理，鍋爐的內(nèi)燃過程實際上是一種極其復(fù)雜的物理化學(xué)反應(yīng)過程，但是由于受燃煤的特性、受熱面上的結(jié)構(gòu)、爐內(nèi)的溫度場水平就越來越高及空氣動力工況等物質(zhì)因素，造成整個受熱面積的灰與結(jié)渣，使鍋爐設(shè)備出力也不斷的下降。而國內(nèi)的動力用煤多使用的是低品劣質(zhì)煤，鍋爐的燃煤多存在變且灰份也非常的大、熱值也在不斷的降低的趨勢，這就自然的加劇著受熱面的積灰結(jié)焦的過程形成。<BR/> With the support of the technical field, the technology and principle of internal combustion in boiler soot blower have been summarized.

鍋爐吹灰器清灰機(jī)理及實現(xiàn)的價值所在

在設(shè)備的運(yùn)行過程中，鍋爐吹灰器以高端的清灰機(jī)理以及自身擁有的性能占據(jù)市場，由于灰粒子的表面的引力、粒子之間及粒子與爐內(nèi)管壁之間存在著一定粘結(jié)力、分子的附著力和靜電引力以及設(shè)備自然存在的化學(xué)親和力等多方面的性能作用，使設(shè)備在爐膛及煙道各部位的換熱面上不斷的逐步形成積灰結(jié)焦。而鍋爐吹灰器中的煙氣灰粒是一種寬篩分組成，所以大部分都是小于220um，其中多數(shù)為10~30um的微小粒。<BR/> During the operation of the equipment, the boiler soot blower occupies the market with its high-end cleaning mechanism and its own performance. Due to the surface attraction of ash particles, the presence of certain bonding forces between particles and the furnace wall, molecular adhesion and electrostatic attraction, as well as the natural chemical affinity of the equipment, and other performance effects, Gradually form ash and coking on the heat exchange surfaces of the furnace and flue of the equipment. The flue gas ash particles in the boiler soot blower are composed of a wide sieve, so most of them are smaller than 220um, with most of them being small particles of 10-30um.
