In the simplest terms, a precipitator is a large box. The dust laden gases are drawn into one side of the box. Inside, high voltage electrodes impart a negative charge to the particles entrained in the gas. These negatively charged particles are then attracted to a grounded collecting surface which is positively charged. The gas then leaves the box up to 99.9% cleaner than when it entered.
Inside the box, the particles from the continuing flow of dust build up on the collecting plates. At periodic intervals, the plates are rapped, causing the particles to fall into hoppers. The particles are then removed from the hoppers, usually by a rotary screw arrangement.

It's a device for purifying gasses. An electric field is generated perpendicular to the flow of 'dirty' gas. The dust and any other crud that's in suspension is attracted to one of the charged plates and clumps up into blobs to heavy to be carried in the air (precipitates) leaving the gas clean. You can usually get it to arou 99% clean. This is usefull for sorting out crude gas that's come out of the ground.

This is also known as an electrostatic precipitator (ESP).
Basically it uses a charged grid to collect ionized dust (dust with an opposite charge to the wires) from the air.
