SBIR Phase I: Clean Air Exhuast Lines Explosion Isolation Device for Combustible Dust Applications

这个小型企业创新研究第一阶段项目的更广泛的影响/商业潜力是为粉末散装处理设施提供更安全的工作环境，同时通过将调节空气回收到建筑物中来帮助设施降低能耗。与可燃粉尘相关的风险是灾难性的，但人们仍然缺乏对风险的认识。 在商业上，该项目将设计一种产品，该产品将安装在粉末散装处理设施上，处理可燃粉尘，防止粉尘燃烧引起的火灾蔓延进入设施的工作区域。 第一阶段研究项目的技术目标是开发一种经济的装置，该装置将作为粉尘爆燃的火焰和压力调节器，同时保持足够的气流通过装置，以使过程平衡。确定适当的网状材料叠层，将熄灭蔓延的爆燃，同时也承受爆燃期间产生的压力，也将有助于扩大可燃粉尘的知识领域，并为它们开发保护设备。通过开发该产品，必须进行额外的全尺寸测试，这将增加可燃粉尘事件如何发生和反应的数据库。

The broader impact/commercial potential of this Small Business Innovation Research Phase I project is to provide a safer working environment for powder bulk handling facilities, while simultaneously helping the facility reduce its energy consumption by allowing it to recycle conditioned air back into the building. The risk associated with combustible dusts are catastrophic, yet the awareness of the risks is still lacking. Commercially, this project would design a product that would be installed at powder bulk handling facilities, that handle combustible dust, that would prevent fire propagation from the combustion of dust from entering the work area of the facility. The technical objectives in this Phase I research project are developing an economical device which will act as a flame and pressure arrestor for dust deflagrations, while maintaining enough airflow through the device to allow the process to be balanced. Determining an appropriate stack-up of mesh material that will quench the propagating deflagration, while also withstand the pressures developed during a deflagration, will also help expand the field of knowledge of combustible dust, and developing protection equipment for them. Through the development of this product, additional full scale test will have to be performed which will add to the database of how combustible dust events occur and react.
