Abstract

A fluid vapor distillation apparatus. The apparatus includes a source fluid input, and an evaporator condenser apparatus. The evaporator condenser apparatus includes a substantially cylindrical housing and a plurality of tubes in the housing. The source fluid input is fluidly connected to the evaporator condenser and the evaporator condenser transforms source fluid into steam and transforms compressed steam into product fluid. Also included in the fluid vapor distillation apparatus is a heat exchanger fluidly connected to the source fluid input and a product fluid output. The heat exchanger includes an outer tube and at least one inner tube. Also included in the fluid vapor distillation apparatus is a regenerative blower fluidly connected to the evaporator condenser. The regenerative blower compresses steam, and the compressed steam flows to the evaporative condenser where compressed steam is transformed into product fluid.

Claims (61)

1. A distillation apparatus comprising:

a source fluid input;

an evaporator condenser apparatus comprising:

a substantially cylindrical housing; and

a plurality of tubes in said housing,

whereby said source fluid input is fluidly connected to said evaporator condenser and said evaporator condenser transforms source fluid into steam and transforms compressed steam into product fluid;

a heat exchanger fluidly connected to said source fluid input and a product fluid output, said heat exchanger comprising:

at least one outer tube; and

at least one inner tube; and

a compressor fluidly connected to said evaporator condenser, whereby said compressor compresses steam, and whereby the compressed steam flows to the evaporative condenser whereby compressed steam is transformed into product fluid, the compressor comprising

an inlet port;

an outlet port;

a stripper plate positioned between said inlet port and said outlet port;

a shaft assembly, wherein the shaft assembly comprising:

a shaft; and

at least one water fed bearing; and

a motor configured to drive the shaft, the motor comprising:

an inner magnet;

an outer magnet; and

a drive motor.

2. The apparatus of claim 1 wherein said inner magnet and said outer magnet are axially positioned one to another.

3. The apparatus of claim 1 further comprising a magnetic coupling shell positioned between said inner magnet and outer magnet wherein said magnetic coupling shell seals steam that is being compressed.

4. The apparatus of claim 1 wherein the heat exchanger is disposed about said housing of said evaporator condenser.

5. The apparatus of claim 1 wherein said heat exchanger further comprising at least three inner tubes.

6. The apparatus of claim 5 wherein said at least three inner tubes are twined to form a substantially helical shape.

7. The apparatus of claim 1 wherein said evaporator condenser tubes further comprising packing inside at least one of said plurality of tubes.

8. The apparatus of claim 7 wherein said packing is a rod.

9. The apparatus of claim 1 wherein said evaporator condenser further comprising a steam chest fluidly connected to said plurality of tubes.

10. A distillation apparatus comprising:

a source fluid input;

an evaporator condenser apparatus comprising:

a substantially cylindrical housing; and

a plurality of tubes in said housing,

whereby said source fluid input is fluidly connected to said evaporator condenser and said evaporator condenser transforms source fluid into steam and transforms compressed steam into product fluid;

a heat exchanger fluidly connected to said source fluid input and a product fluid output, said heat exchanger comprising:

a compressor fluidly connected to said evaporator condenser, whereby said compressor compresses steam, and whereby the compressed steam flows to the evaporative condenser whereby compressed steam is transformed into product fluid, said compressor comprising:

an inlet port;

an outlet port;

a shaft assembly wherein said shaft assembly comprising:

a shaft; and

at least one water fed bearing; and

a motor configured to drive said shaft, the motor comprising:

an inner magnet;

an outer magnet; and

a drive motor.

11. The apparatus of claim 10 further comprising a stripper plate positioned between said inlet port and said outlet port.

12. The apparatus of claim 10 wherein said inner magnet and said outer magnet are axially positioned one to another.

13. The apparatus of claim 10 further comprising a magnetic coupling shell positioned between said inner magnet and outer magnet wherein said magnetic coupling shell seals steam that is being compressed.

14. A compressor comprising:

an inlet port;

an outlet port;

a shaft assembly, wherein said shaft assembly comprising:

a shaft; and

at least one water fed bearing; and

a motor configured to drive said shaft, the motor comprising:

an inner magnet;

an outer magnet; and

a drive motor.

15. The apparatus of claim 14 further comprising a stripper plate positioned between said inlet port and said outlet port.

16. The apparatus of claim 14 wherein said inner magnet and said outer magnet are axially positioned one to another.

17. The apparatus of claim 14 further comprising a magnetic coupling shell positioned between said inner magnet and outer magnet wherein said magnetic coupling shell seals steam that is being compressed.
