A Brief History of Acoustic Cleaning Systems声波吹灰系统简史Drayton Corporation 1983 to 19991983年至1999年，德雷顿公司Drayton Corporation was incorporated in 1983 in the state of Alabama. The company manufactured the Sound-Off) Acoustic Cleaners. The company was started by two brothers, Jeff Shelton and Jake Shelton. Drayton Corporation was the first acoustic cleaner company in the United States that focused primarily with the installation of acoustic cleaners on boilers and electrostatic precipitators.德雷顿公司于1983年在美国阿拉巴玛州成立。该公司生产消音声波吹灰器。公司由Shelton兄弟，Jeff Shelton 和 Jake Shelton，设立经营。德雷顿公司是美国首家致力于将声波吹灰器安装于锅炉和静电除尘器上的声波吹灰器厂家。Milestone Events:重大事件：In 1986, Jeff Shelton designs the first acoustic cleaner with a fundamental frequency of 75 Hz,the Sound-Off Acoustic Cleaner Model ESP-75. This acoustic cleaner was designed for service on electrostatic precipitators. The Drayton Corporation series of 75 Hz acoustic cleaners quickly became the most widely applied model of acoustic cleaners. The extensive cleaning area provided by the 75 Hz acoustic cleaner enabled Drayton Corporation to use it on a variety of applications: baghouses, boilers and many others.1986年，Jeff Shelton设计了首台带有基频为75赫兹的声波吹灰器，即ESP-75型消音式声波吹灰器。该声波吹灰器专门为静电除尘器而设计。德雷顿公司的75赫兹声波吹灰器系列产品很快成为被广泛使用的声波吹灰器。75赫兹声波吹灰器所提供的延伸清灰区域使德雷顿公司将其运用于不同的领域：布袋除尘器，锅炉以及其他许多方面。In 1997, Drayton Corporation installed the first set of acoustic cleaners on a Selective Catalytic Reduction (SCR) reactor following a coal-fired boiler in the United States.1997年，德雷顿公司第一次在美国一燃煤锅炉的SCR（选择性催化还原）反应器安装了声波吹灰器。In January of 1999, Drayton Corporation sold the Sound-Off Acoustic Cleaner product line to the BHA Group. BHA was a world leader in innovative filtration technology. It was a leading global supplier of replacement parts and services for industrial air pollution control systems. To insure that the acquisition was successful, Jake Shelton went to work for BHA Group. His title at the BHA Group was the Technical Director, Acoustics.1999年1月，德雷顿公司将消音式声波吹灰器生产流水线出售给了BHA集团公司。BHA为世界创新过滤技术的先驱。它是全球提供工业用空气污染控制系统部件更换以及服务的知名企业。为了保证其成功地收购，Jake Shelton赴BHA 集团公司工作。他在BHA集团公司的职位头衔为声波部门技术总监。BHA Group 1999 to 20041999年至2004年BHA集团公司The following is a paragraph from BHA Group Holdings, Inc. 10-K405 Filing for the year of 1999.以下摘自BHA集团控股公司1999年版编号为10-K405文件中的一段文字。In addition to standard replacement parts, the Company continues to aggressively introduce new products and accessories that enhance the performance of a dust collection system. These new products include continued enhancements to the Companys electrical products for both baghouses and precipitators and the introduction of pleated media filter elements and evaporative gas cooling product lines. Internal product development continues to be supplemented with strategic acquisitions such as the Drayton Corporations sound-off acoustic cleaner product line acquired in January 1999. By combining the Drayton horn line with the companys other acoustic products, BHA now has the most comprehensive line of acoustic horns in the industry.除了标准替换部件后，公司不断推出能提高灰尘收集装置性能灰尘新产品和附件。这些新产品包括不断提高公司为布袋除尘器和除尘器配备的电子产品，褶边介质过滤单元以及水蒸汽冷却生产流水线的引入。有关战略性的收购能不断扩充内部产品发展， 诸如德雷顿公司于1999年一月收购消音式声波吹灰器生产流水线。在将德雷顿声波喇叭生产流水线与公司的其他声波产品组合后，BHA 现在已具有在该工业领域内最全面的声波吹灰产品线。In March of 1999, BHA Group began using the PowerWave trademark to describe the acoustic cleaner product line including the Sound-Off Acoustic Cleaner product line purchased from Drayton Corporation.1999年3月，BHA集团公司开始使用PowerWave商标来表示其所有声波清灰器产品线，包括从德雷顿公司处购进的消音式声波吹灰器生产流水线在内。On Friday, March 12, 1999, a U.S. federal trademark registration was filed for POWERWAVE by BHA Group, Inc., KANSAS CITY, MO 64133. The USPTO has given the POWERWAVE trade mark serial number of 75659469. The description provided to the USPTO for POWERWAVE is cleaning device for industrial air pollution control equipment, namely, acoustic horns and replacement parts to produce low frequency and high intensity sound waves that loosen collected or impacted dust and debris without damaging the equipment.1999年3月12日星期五，美国联邦商标注册局在美国堪萨斯城MO64133为BHA集团公司的POWERWAVE做了商标注册。USPTO给予POWERWAVE的商标的序列号为75659469。提供给USTPO关于POWERWAVE商标的描述为：声波喇叭及其配件，工业用空气污染控制设备的清洁装置，可以发出低频高能的声波，在不损坏设备的情况下松动收集到的或积聚的灰尘和颗粒。The following is an abstract retrieved from the internet.以下内容为互联网上的简要截取。Acoustic Cleaners on SCR Reactors, Jake Shelton, BHA Group Inc. JsheltonBHA.comIn the early 90s, when the US Utility Companies began implementing SCR reactors on coal-fired boilers, the only proven on line catalyst cleaning system was conventional soot blowers. That is no longer true! At this time, there are more than 80 SCR reactors being cleaned by the acoustic energy emitted from acoustic cleaners (sonic horns). The acoustic cleaners have proven effective on high dust and low dust reactors following boilers burning a variety of coals including PRB. Experience has also shown that the acoustic cleaners are effective on the different catalyst designs: plate, honeycomb and corrugated.在20世纪90年代初期，当美国电力公司开始在燃煤锅炉上配备SCR反应器时，唯一被公认的在线催化剂清灰系统为传统的蒸汽吹灰器。那不是真的！如今，有80多个SCR反应器由声波吹灰器（声波喇叭）释放出的声波能量来进行清灰。声波吹灰器已经证明对锅炉燃烧后产生的高浓度以及低浓度的灰尘都能有效清灰，包括PRB煤等各种煤种。经验显示声波吹灰器对不同的催化剂形式：平板式，蜂窝式以及波纹式，都有良好的效果。The US Utility Industry has used acoustic cleaners since the early 80s. The most common applications for the acoustic cleaners have been baghouses, precipitators and the back passes of boilers. Areas where the ash deposits are dry. The first SCR reactor installation in the US took place in 1997. The acoustic cleaners were installed on a trial bases to replace some out of service steam soot blowers. The trial installation proved successful, and the plant eventually replaced all of the soot blowers on the SCR reactor with acoustic cleaners. Please refer to the paper titled “A Sound Method of Cleaning SCR Reactors” for more details on this installation. As the implementation of SCR reactors began to heat up in US, BHA began actively promoting the use of acoustic cleaners in lieu of soot blowers. The first hurdle for BHA to overcome was to confirm that the acoustic energy emitted by the acoustic cleaners would not damage the catalyst. This was done by doing lab and field-testing with several of the major catalyst suppliers. All of the testing proved that the low frequency (75 Hz), high-energy (147 dB) sound waves did not cause any structural damage to the catalyst. In fact, most people believe that the acoustic cleaners will prove to be a much more gentle cleaning system to the catalyst than the erosive cleaning action of soot blowers.美国电力行业自20世纪80年代初期已开始使用声波吹灰器。声波吹灰器最常见的应用是锅炉的布袋除尘器、电除尘以及尾部烟道。那些堆积干燥灰尘的区域。1997年美国安装了首台SCR反应器。基于试用的目的，安装了声波吹灰器以替换那些停用的蒸汽吹灰器。试用被证实是成功的，最终整套系统的SCR反应器上的所有吹灰器都被替换成了声波吹灰器。请参考题为“SCR反应器清灰的有效方法”的文章，其中有关于此次安装更多地详细内容。在美国SCR 反应器的安装开始越来越多时，BHA已积极地推广声波吹灰器的运用，以此来取代吹灰器。BHA遇到的首个需要克服的障碍就是确认从声波吹灰器中释放出的声波能量不会对催化剂有破坏作用。这已经由几个主要催化剂供应商经过实验室以及现场测试后得到了验证。所有的测试证明低频(75 Hz)、高能量 (147 dB) 的声波不会引起对催化剂的任何结构破坏。事实上，许多人相信声波吹灰器将被证实是一种比蒸汽吹灰器对催化剂进行的腐蚀性清灰更为轻柔无伤害的清灰系统。The next step for BHA was to prove that the acoustic cleaners were at least equally as effective to the cleaning action of soot blowers on this application. To prove this point, BHA supplied acoustic cleaners to several different utility companies to do side by side comparisons. These companies operated the acoustic cleaners on at least one reactor and operated soot blowers on other reactors treating the flue gas from the same boiler. In every side-by-side evaluation, the acoustic cleaners have been selected as the preferred cleaning system. For more information on one such comparison, please refer to the technical paper titled “TVA, Paradise Fossil Plant Powerwave Acoustic Cleaners vs. Soot blowers”.BHA的下一步是证明在此应用中，声波吹灰器至少与吹灰器有同等的清灰效果。为证明这点， BHA向几家不同的电力公司提供了声波吹灰器，以便做对照比较。这些公司在至少一台反应器上运行声波清灰器，并在来自于同一锅炉烟气的另一个反应器上运行蒸汽吹灰器。在每一个对比评估中，声波吹灰器被视为首选的清灰系统。想要获取更多关于此对比的详细信息，请参照名为“TVA，Paradise 燃煤电厂-Powerwave声波清灰器vs蒸汽吹灰器”的技术文献。Once the acoustic cleaners proved to be an effective catalyst cleaning system that would not damage the catalyst, the utility plants began seriously considering the use of acoustic cleaners instead of air and/or steam soot blowers. The economic justifications to use the acoustic cleaners were so tremendous that utility plants began requesting the use of acoustic cleaners on the SCR reactors being designed and built by the SCR OEMs. BHAs first contract from a SCR OEM was obtained in the summer of 1999. Since that time, BHA has supplied thousands of acoustic cleaners to all of the SCR OEMs and has worked with the majority of the A&E firms involved in the US SCR market. It is estimated the BHA has saved the US Utility Industry approximately 50 million dollars in SCR equipment and construction costs.一旦声波清灰器被证明是一种有效的、不会对催化剂造成损伤的催化剂清灰系统，各个电厂就开始认真考虑使用声波吹灰器来替代空气或蒸汽吹灰器。使用声波吹灰器的经济效益是巨大的，以致各个电厂开始要求SCR OEMs在设计和制造的SCR反应器上使用声波吹灰器。BHA于1999年夏季获得SCR OEM的首个合同。从那时起，BHA向所有的SCR OEMs提供了上千套声波吹灰器，和美国SCR 市场主要的A&E公司都有合作。据估计，BHA 为美国电力行业节约了5千万美元的SCR设备和安装成本。BHA/GE Energy 2004 to 20102004年至2010年 BHA/GE 能源GE Energy to Acquire BHA Group Holdings, Inc., A Leader in Air Quality ControlGE 能源 收购 BHA集团控股公司，空气质量控制的领军企业ATLANTA, GEORGIA (June 1, 2004) GE Energy has signed a definitive agreement to acquire BHA Group Holdings, Inc., a leading provider of air quality control products and services, in an all cash transaction for $38 per share or approximately $260 million.
