SBIR Phase I: Vibration-Based Cleaning for Ash Removal from Diesel Particulate Filters

这个小型企业创新研究(SBIR)第一阶段项目将研究使用振动来清除和去除陶瓷过滤器上积累的污染物的可行性。滤清器传感技术(FST)将柴油颗粒滤清器(DPF)作为一种有前景的应用，因为它们价格昂贵，并被广泛使用，以满足强制排放法规。随着时间的推移，这些过滤器会被灰烬堵塞，而目前的清洁系统很难将其清除，因为灰烬会塞进通道末端的插头。清洗效率低下会导致燃油处罚，增加维护成本，并降低滤清器的使用寿命？S。FST建议使用振动来比目前的清洁方法更有效地清除灰烬。这项研究将调查该系统在确保过滤器完整性的同时粉碎和去除DPF中的灰分的效果。这项研究的更广泛的商业影响是，它可以满足改善DPF灰分清洁的重大未满足需求，提供成本节约和环境效益。目前的灰尘清洗系统的价格从25,000美元到100,000美元以上不等，并且都会在DPF中留下一些残留的灰烬。S提出的清洁系统每年可以为最终用户节省超过2,500美元的燃料和维护成本，而这只是一辆典型重型卡车的一小部分成本。目前的估计显示，美国和欧洲的DPF清洁市场在2010年将产生超过60亿美元的收入，到2014年将几乎翻一番。FST？S技术提供了更有效、更简单、更便宜的解决方案，能够节省燃料并提高排放控制系统的性能。

This Small Business Innovation Research (SBIR) Phase I project will investigate the feasibility of using vibrations to dislodge and remove contaminants accumulated on ceramic filters. Filter Sensing Technologies (FST) has targeted diesel particulate filters (DPF) as a promising application, since they are expensive and in widespread use to meet mandated emissions regulations. Over time these filters become plugged with ash, which current cleaning systems can not easily remove, as the ash packs in plugs at the end of the channels. Inefficient cleaning results in fuel penalties, added maintenance costs, and reduces the filter?s life. FST proposes to use vibrations to remove ash more effectively than current cleaning methods. This research will investigate the efficacy of this system to break-up and remove ash from the DPF, while ensuring filter integrity.The broader/commercial impacts of this research are that it can satisfy a significant unmet need to improve DPF ash cleaning, providing both cost savings and environmental benefits. Current ash cleaning systems range in price from $25,000 to over $100,000 and all leave some residual ash in the DPF. FST?s proposed cleaning system can provide annual fuel and maintenance cost savings to the end-user of over $2,500 for a typical heavy-duty truck, at a fraction of the cost. Current estimates show the US and European DPF cleaning market will generate over $6B in revenues in 2010 and nearly double by 2014. FST?s technology provides a more effective, simpler, and less expensive solution, enabling fuel savings and improved emission control system performance.
