Novel Electrostatic Precipitator Concept with Controlled Solids Reentrainment and Turbulence

污染控制技术的进步在美国被视为高度优先的事项。其中一个重要步骤涉及开发超高性能系统，用于去除处理流或工厂污水中的细颗粒物。在这个项目中，LSR Technologies，Inc.将研究和开发一种新的静电除尘器(ESP)概念，该概念具有可控的固体再卷吸和湍流强度。该概念消除了传统电除尘器普遍存在的以下缺陷：粉尘电阻率高或低；颗粒空间电荷效应；气体和破碎的粉尘层混合造成的振打再卷吸；以及料斗上方除尘器下方泄漏造成的渗漏。它还降低了电除尘器内的湍流强度，进而提高了气/固分离效率。第一阶段的研究将集中于原理验证测试，其中将包括分析控制湍流强度对除尘器性能的影响。第二阶段的工作将包括在试点规模进行广泛的测试。

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.
