Electrostatic Precipitator Unit

The electrostatic precipitator (ESP) unit is designed with the industrial units in mind. In this design, pressurized gas flows into the water trap and is forced into the ESP through the small inlet holes in the “cap”. This is an attempt to lower the pressure of the gas and allow for water vapor to be formed more easily. Similar to the simple water bottle physics trick, which forms water vapor out of the compressed air inside the bottle, which is suddenly reduced in pressure. The ESP works as an anode and cathode and draws the thinned out water vapor to collect on the concentric plates. The path followed by the H2 narrows before entering the final section into the exit tube. Low voltage positive and negative wires are secured into their respective fittings via simple screws. Current can be drawn from the electronics already inside the electrolyser unit and electronics added. Because the ESP unit is designed to be copper, an electrical insulating coating is to be applied to the outside of the fittings, and a low conductivity metal/coating are assumed to be used for the outer water trap tube. To purge water, holes are machined into the base of the lower ESP fitting. These holes are blocked using a simple corrosion resistant (CR) washer seal backed by a CR washer, and held in place using a simple CR screw and CR disk spring. The disk spring is meant to compress during opening of the purge line. Pressure difference between the ESP and purge line provides the necessary force required to compress the disk spring and allow water to flow passed. This design iteration has the outermost purge holes plugged, however, the previous iteration had them open to provide a more equal pressure, allowing for a weaker disk spring to be utilized.
