The advancement of pollution control technologies is being treated as a high priority in the U.S. One important step involves the development of ultra-high performance systems for the removal of fine particles from processing streams or plant effluents. In this program, LSR Technologies, Inc., will investigate and develop a novel electrostatic precipitator (ESP) concept with controlled solids reentrainment and turbulence intensity. The concept eliminates deficiencies generic to the conventional ESP and associated with: high or low dust resistivity; particulate space charge effects; rapping reentrainment due to mixing of gas and broken dust layers; and seepage due to leakage from below the precipitator over the hoppers. It also reduces the intensity of turbulence in the ESP, in turn improving gas/solids separation efficiency. The Phase I research will focus on proof-of-principle testing which will include an analysis of the effect of controlling turbulence intensity on precipitator performance. The Phase II effort would include extensive testing at the pilot-scale level.

污染控制技术的进步在美国被视为高度优先事项。其中一个重要步骤涉及开发超高性能系统，用于从加工流或工厂废水中去除细颗粒。在这个项目中，LSR技术公司，将研究和开发一种新的静电除尘器（ESP）的概念与控制固体再夹带和湍流强度。该概念消除了常规ESP的一般缺陷，并且与以下相关：高或低粉尘电阻率;颗粒空间电荷效应;由于气体和破碎粉尘层的混合而引起的振打再夹带;以及由于从除尘器下方到料斗上方的泄漏而引起的渗漏。它还降低了ESP中的湍流强度，从而提高了气/固分离效率。第一阶段的研究将侧重于原理验证测试，其中将包括控制湍流强度对除尘器性能的影响的分析。第二阶段的工作将包括中试规模的广泛测试。
