it's not a giraffe

chupmaderchod — Preceding unsigned comment added by 117.200.227.138 (talk) 14:42, 12 July 2015 (UTC) someone stated that an electrostatic precipitator was a rare species of arctic giraffe discovered by Charles Darwin(who never went to the arctic as far as I know). I have undo their edits, If some one could please double check to make sure there wasn't anything else removed by the undo. anoyanort ace Matthew ave jor (talk) 17:20, 7 December 2007 (UTC)

scrubber article?

It seems like this article and the "scrubber" article should be more interconnected. I don't claim to be an engineer, but seems like the majority of industrial processes for an electrostatic precipitator will fall into the category of also being a scrubber.

Merge? — Omegatron 19:27, 25 October 2006 (UTC)

No, please don t. A precipitator has nothing in similar with a scrubber...

FYI on updated Cottrell link

The Cottrell link has been updated to point to a new bio stub. I also incorporated the paragraph below the link about Research Corporation into that stub (FYI). -regards,Onceler 23:30, 31 December 2005 (UTC)

Confused

"Once the particles are in contact with the positive plate, they then give up their electrons and become positively charged like the plate, and thus start acting as part of the collector."

Wouldn't the fact that they become positively charged mean they are repelled from the positively charged plates? This is what happens to pith balls/hairs/paper shreds on a charged metal object, for instance. They are attracted at first, contact the metal object and become charged the same way, and then are suddenly repelled. — Omegatron 19:29, 25 October 2006 (UTC)

Copy / Paste?

who's copying from who? http://www.answers.com/topic/electrostatic-precipitator

Answers.com mirrors Wikipedia. They say so quite clearly. — Omegatron 21:13, 11 January 2007 (UTC)

i am doing masters degree in chemical engineering from a reputed institute in India.....well i am new to this site......i do not know much about this....please refer all available options and facilities to me... — Preceding unsigned comment added by Kshitijkaushik 84 (talk • contribs) 18:29, 1 March 2007 (UTC)

Any Research on Low Voltage Devices?

How low could one go in voltage and still be able to clear the room air of dust? 71.114.163.55 (talk)

This depends on the size of the room, and the time which is allowed to clean the room. It does not make sense if it is possible to clean the room, but it takes a few months for it...

Why does Sir Oliver Lodge not get a mention?

"In 1886 the first attempt on a commercial scale to precipitate dust and fume from gas was made by Oliver Lodge and Mr A. O. Walker at Deeside Lead Works, Chester." direct quote from the Lodge Cottrell ltd page. —Preceding unsigned comment added by 78.146.157.128 (talk) 20:15, 6 June 2009 (UTC)

Suggested addition to the text

At the end of the section for "Modern industrial electrostatic precipitators" i would like to suggest that the following text is added. Any comments/contributions would be appreciated

"These ‘rapping systems’ are usually mechanically operated by means of rows of staggered rotating ‘hammers’ which strike the plates in turn. This constant mechanical hammering action can sometimes cause internal damage which can result in sections of the ESP becoming inoperative and therefore reducing the overall efficiency of the ESP. A decision then has to be made as to whether to commence an unscheduled shutdown to carry out repairs or to continue operating the ESP in its damaged state until the next planned shutdown is due. Largely because of this, sonic soot blowers are installed to either partially or fully replace the mechanical rapping systems. These sonic soot blowers use non-destructive high energy-low frequency sound waves which prevent the particulate from building up on the collecting plates."

Other electrostatic air filters?

On ther internet I find alot of what are called "electrostatic air filters". Yet on comparison there workings seem somewhat different than the wikipedia article. The air filters are loaded through friction of the air en dust is attracted. (No two parts with a voltage difference, no collector plates, no ozone, aso...) For example: http://www.dustfree.com/filters/faq.htm http://acfilter.com/categories/faq/faq.htm http://www.lifetimeelectrostaticfilter.com/ Even if these are bogus: aren't they worth a mention? — Preceding unsigned comment added by BartYgor (talk • contribs) 15:16, 17 April 2011 (UTC)

Removing picture of consumer air cleaner

I removed these pictures.

A portable electrostatic air cleaner marketed to consumers

This is is a HEPA-based air purifier with a proprietary "PlasmaCluster" ion generator on the exhaust. This device generates oxygen and hydrogen ions that, supposedly, will chemically attack pollutants. Han-Kwang (t) 18:49, 5 December 2021 (UTC)
