Abstract
A water processing device for removing contaminants from water for consumption, consisting of: 1) a heat exchanger; 2) a heater; 3) a boiler chamber; 4) a liquid level control device; 5) a demister; 6) a degasser; and, 7) a self-cleaning component. A water seal to prevent steam from leaking from the device is also provided.
Claims8
A water processing device for removing contaminants from water comprising:
- a) a boiler having a cavity and an upper surface and a bottom surface of the cavity for receiving and boiling the feed water from the heat exchanger to generate product in the form of steam;
- b) a heater for boiling said feed water in the boiler;
- c) a degasser for removing noncondensible gases from said feed water;
- and
- d) a demister for removing droplets containing contaminants from the product steam, whereby the product steam exiting from the demister is cooled to liquid form in said heat exchanger and recovered as processed liquid product.
A method for preventing exit of gas around a shaft in a cavity that extends through an aperture where the bottom of the shaft is under liquid in the cavity, comprising inserting a shaft through a hollow tube of greater diameter than the diameter of said shaft where the bottom of the tube lies beneath the surface of a liquid that is under pressure in the cavity, said liquid entering the hollow tube through the bottom until the pressure outside the tube in the cavity and the weight of the water in the tube are equal.
