Abstract

The system includes a tank for receiving water, a microwave unit having a plurality of sides, one of the sides having a first opening and a second opening, the microwave unit housing a vessel for receiving water from the tank, the vessel having a lid including an inlet port extending through the first opening and an outlet port extending through the second opening, the inlet port of the vessel being positioned in fluid communication with the tank, a magnetic stirrer having a stir bar immersed in the water contained in the vessel, and a condenser unit having a natural convection condenser positioned within a first tube, an adapter, and a heat exchange coil having an inlet configured for receiving water from the tank and an outlet for discharging water to the tank, the condenser unit being positioned in communicating relation to the outlet port of the vessel.

First claim

We claim:

1. A microwave-assisted distillation system, comprising:
a tank configured for receiving water;
a microwave unit having a plurality of sides, one of the sides having a first opening and a second opening defined therein, the microwave unit including a magnetron, wherein the magnetron is configured to produce microwave radiation within the microwave unit to heat the water contained therein to a predetermined temperature;
a vessel housed in the microwave unit, the vessel having a lid including an inlet port extending through the first opening and an outlet port extending through the second opening, the vessel being in fluid communication with the tank;
a temperature sensor positioned in direct communicating relation with the vessel in order to measure the temperature of the water inside the vessel;
a temperature controller configured for activating the magnetron, the temperature sensor communicating with the temperature controller;
a magnetic stirrer having a stir bar, the stir bar being disposed in the vessel; and
a condenser unit, including:
a natural convection condenser positioned within a first tube having a first end and a second end, the first end of the first tube being coupled to the outlet port of the lid;
an adapter having a first end and a second end, the first end of the adapter being coupled to the second end of the first tube;
a second tube having a first end and a second end;
a heat exchange coil having an inlet configured for receiving water from the tank and an outlet configured for discharging water into the tank, the heat exchange coil being disposed within the second tube, the first end of the second tube being coupled to the second end of the adapter and the second end of the second tube being configured for discharging distilled water into a receiver at least one cooling plate within the tank wherein the at least one cooling plate is coupled to the outlet of the heat exchange coil; and

wherein the tank includes an exhaust fan in communicating relation with the at least one cooling plate.

2. The microwave-assisted distillation system according to claim 1 , further comprising an entry line coupled to the tank, the entry line having a filter and a carbon filter, the filter being positioned adjacent to the carbon filter.

3. The microwave-assisted distillation system according to claim 1 , further comprising a power source, the temperature controller selectively receiving power from the power source.

4. The microwave-assisted distillation system according to claim 3 , wherein the power source is selected from the group consisting of a generator, solar panels, and wind turbines.

5. The microwave-assisted distillation system according to claim 1 , further comprising a pump operatively coupled for pumping the water from the tank throughout the system.
