Abstract:

A splash shield for the boiler of a distillation type water purification apparatus includes at least two grades of porous media which cooperatively inhibit bubble formation and splashing, thereby preventing transfer of contaminants from the boiler water to the upper, interior surfaces of the boiler and into the distilled, contaminant free water. A first porous media is open cell reticulated foam having relatively large cells. Typically, at least a portion of the open cell foam is disposed above the operating liquid level of the boiler. The second porous media is fabric or screen having pores preferably smaller than about one thousand microns. The screen is disposed above the liquid level of the boiler. The open cell foam inhibits bubble production and breaks down bubbles and the screen intercepts drops and droplets that might otherwise travel to, contact and contaminate the upper boiler chamber surfaces and output to a condenser. The screen is preferably secured to a peripheral gasket which facilitates sealing engagement between the upper and lower halves of the boiler.
