Removing Diesel Exhaust Particulate with Parallel-plate Hole-type Electrostatic Precipitator

An Overview of Current-Voltage Characteristics Estimation from Plate-Type Electrostatic Precipitator with Three Sections

The paper presents a theoretical analysis on the dynamic characteristics of the current-voltage characteristics of plate-type electrostatic precipitators (with three fields) from an electric power station. Measures were made with signal conditioning, data acquisition card, and PC. It was found that these characteristics can not be mathematically model, due to their permanent modification (have ...

Diesel PM Collection for Marine Emissions Using Double Cylinder Type Electrostatic Precipitator

Low resistive particulate matter (PM) generated from marine engines or diesel generators has been known to be difficult to collect by the conventional electrostatic precipitators (ESP). In the present study, the double-cylinder type ESP (DC ESP) was developed to remove low resistive diesel exhaust particles. Two ESPs, namely, the conventional singlecylinder type ESP (SC ESP ) and DC ESP were in...

Investigations on Particle Dynamics in a Plate Type Electrostatic Precipitator Using Double-pulse Holography

The separation of particles from gases within electrostatic precipitators is mainly depending on the flow conditions. The flow field is governed by the mutual interaction of the electric field with the gas ions and the turbulent channel flow. Especially for wire-plate electrostatic precipitators this causes secondary flows, well known as the 'ionic wind'. The influence of the ionic wind on the ...

Parallel-plate electrostatic actuation with vertical hinges

A microactuating structure with vertical polyimide hinges has been designed, fabricated and tested. Unlike traditional microactuators, which are located on the substrate surface, this new actuation mechanism is capable of producing linear motion at a point far from the substrate. This advantage can make it possible to drive other out-of-plane folded structures for on-wafer or out-of-wafer appli...
