Electrostatic precipitator is the equipment that separates dust particles from the gas in which they are suspended. Specially, for the construction of industrial electrostatic precipitator, the corporations would send the layout design to a customer to accept an order. Therefore, it is made a detail drawing after accept ance. Since the layout design of electrostatic precipitator is very complex, it takes time and design errors are included. Thus, for competitiveness in these industries, the development of software for the layout design of electrostatic precipitator is important. In this study, the developed software deals with technical concept and layout design of industrial electrostatic precipitator. By using the software, design time was very short, design errors reduced largely, and the standardization of design could be carried out.

Electrostatic precipitator is the equipment that separates dust particles from the gas in which they are susponded. Specially, in establishing industrial electrostatic precipitatior, corparations would send to a customer technical papers to accept an order. And, they design detail drawing after accept an order. Then, since the basic technical design of electrostatic precipitator is very complex, it takes long time. Thus, for competitiveness in these industries, the developement of software about technical design is important. In this study, the developed software is called 'KOCO', the simpler form for KOrea Cottrell Co. Ltd., deals with a basic technical design of industrial electrostatic precipitator. From using the software, design time was veryshort, design errors reduced largely, and the standardization of design could be carried out.

This study conducts a laboratory measurement on a cylindrical electrostatic precipitator(ESP) with a 30mm-diameter cylinder. Several kinds of test aerosols are generated with an atomizer and a diffusion dryer. The effects of applied voltage, flow state, gas velocity, and gas temperature on the electrical characteristics of the precipitator and onset of corona are experimentally investigated. The corona onset voltage is decreased, as diameter of discharge electrode wire becomes small or temperature of the precipitator increases. As the fluid velocity or particle load in the precipitator increases, the corona current is decreased.

This study Investigates the effect of the wave form of pulse energization on the collection characteristics of a wide plate spacing electrostatic precipitator. For the semi-pulse energization, the peak current and voltage of the energization increases with increase of the pulse period, and the corona current increases, as pulse ratio decreases. For the micro-pulse energization, the corona current increases with increase of the pulse voltage. The collection efficiency of semi-pulse and micro-pulse energization is larger than that of DC charge.

전기집진기는 여타의 집진 설비에 대한 집진 효율과 유지 보수성이 우수한 설비이며 소결공장의 배출분진과 같은 고온($120{\~}160^{\circ}C$)의 미세분자($5{\~}12{\mu}m$) 및 고비저항($10^{12}{\~}10^{13} {\Omega}cm$)을 포집할 때 DC 하전에 비해 Pulse 하전이 효과적이며 Energy 절감이($60{\~}90\%$) 된다. 본 논문은 소결공장의 DC 하전에서 Pulse 하전으로 전환 시 EP 특성 및 부하변화에 따른 제어방안을 제시한다. 현재 제철소의 소결 전기집진기 경우 정수 직후에는 전압이 정상적으로 공급하다가 시간이 지남에 따라서 DC 전압이 낮아지고 Back Corona 현상이 발생하여 서서히 분진농도는 급격히 상승하는 문제점을 가지고 있다. 이에 비해 Pulse 하전으로 운전할 경우에는 Back Corona 현상 발생억제로 출구농도 상승 기울기를 조장방법 및 Ramping 장치와 관련장치 등을 최적으로 운용할 수 있는 방법을 소결공장 실험하였다.

This study investigates the effect of the wave form of pulse energization and dust concentration on the collection characteristics of a moving electrode electrostatic precipitator (MEEP). Under the same specific corona power, the collection efficiency of the MEEP for the lower dust concentration ($2g/m^3$) becomes higher than that for the higher concentration ($10g/m^3$). Both the collection efficiency and specific corona power increase with increasing pulse period for the same value of applied voltage. The collection efficiency of MEEP is higher than that of the conventional fixed plate electrode electrostatic precipitator.

The objective of this study was to evaluate particle collection performance of electrostatic precipitator (ESP) integrated with double skin façade in naturally ventilated residential buildings using numerical method. To evaluate the efficiency, computational fluid dynamics (CFD) simulation based on electric potential and Lagrangian method was applied. The CFD model was validated by comparing the simulated results with the experimental data including thermal characteristic of double skin façade (DSF) and particle removal characteristic of electrostatic precipitator. The validation results showed that the root mean square error (RMSE) between predicted values and measured values of velocity and temperature in intermediate space of DSF was 1.2%. The adequacy of ion space charge density and turbulent model were determined. The RMSE between predicted values and measured values of collection efficiency of ESP was 9.2%. In addition, the case study was performed to present the application of the numerical method based on validation results of ESP integrated with façade.
