Particle drift velocity V d 0. Gas flow rate is a fundamental factor in the design and performance of electrostatic precipitator.

Electrostatic Precipitator For Fine And Ultrafine Particle Removal From Indoor Air Environments Sciencedirect

This means that particle mobility will decrease as gas viscosity increases that is with increasing gas tem- perature.

. The calculation of the parameters of the electrostatic precipitator starts with the selection of the corona discharge Fig. Used to determine the collection efficiency of the precipitator under ideal conditions. The collection efficiency of an electrostatic precipitator may be estimated by an empirical equation 2014 R 1 exp A v d Q where A total area of the collecting surface of the collection electrodes m 2 Q flow rate of gas through the.

Modeling the electrostatic field Defines characteristics of electric discharges Defines forces over the particles Poisson equations Calculation method Potential and field. It is designed to trap and remove dust particles from the exhaust gas stream of an industrial process by using the force of an electric field.

Iterative FDM algorithm Finite Differences Method with convergence verification Electrostatic field Orthogonal embedded grid Calculation domain. The manufacturer designs and sizes the electrostatic precipitator. DISCHARGE ELECTRODE HIGH VOLTAGE SUPPORT FRAME The power supplies for the ESP con-vert the industrial AC voltage 220-480 V to pulsating DC voltage in the range of 20000-100000 V as needed.

Gas flow rate Q. EPA United States Environmental Protection Agency EPA-600R-04-072 July 2004 Electrostatic Precipitator ESP Training Manual Proneilwi tor 00. The intensity of electrostatic field at which the corona discharge occurs is called critical and can be calculated with the formula 1.

However the operator or reviewer needs to check or estimate the collection efficiency and the amount of collection area required for a given process flow rate. An electrostatic precipitator ESP is defined as a filtration device that is used to remove fine particles like smoke and fine dust from the flowing gas. Collection efficiency R 0.

It is the commonly used device for air pollution control. Particle drift velocity V d 0. Design of electrostatic precipitators.

Gas flow rate Q 0. An electrostatic precipitator ESP is a large industrial emission-control unit. See Figure 614 for examples of typical flate-plate and plate-wire ESP configurations.

Electrostatic Precipitator Efficiency Calculations Joe O. We need Electrostatic Precipitator in order to reduce pollutants emitted into. The obtained results showed that the adopted design of the electrostatic precipitator enables the reduction of dust emissions generated in the combustion of solid fuels in households at relatively.

The air passes through a negatively charged metal rod between a positively charged collection. The efficiency of the electrostatic precipitator is dependent on the particle size of the aerosol dust mist to be collectedThe collection efficiency if high for more massive particles and low for small particlesThe formula to calculate the efficiency. An Electrostatic Precipitator ESP is a device that is used to remove and collect the particles from a flue gas by.

4 the wet precipitator which may have any of the previous mechanical configurations. The volume flow rate through. Industrial Gas Cleaning Institute.

Electrodes collecting area A 0.

0 0 0. 2 the flat plate precipitator 3 the tubular precipitator. They are used in industries like steel plants thermal energy plants.

Gas flow rate Q 0. Described here are 1 the plate-wire precipitator the most common variety. Similarly particle velocity is opposed by the gas vis- cosity.

21 Design As mentioned earlier an ESP is a device that separates particles in a gas in this case air. Ledbetter The University of Texas at Austin Electrostatic precipitator ESP collection efficiency has long been calculated by the Deutsch equation1 y l q 1 exp-wAQ 1 Copyright 1978-Air Pollution Control Association 1228 where rj efficiency of collection q penetration w mi-. In its simplest form this model is given by where 7 - 1 - e- AwQ ZwPv 1 The term w is visualized as representing the component of the average particle velocity in the direction perpendicular to the aerosol flow and is.
