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. The fluid vapor distillation apparatus also includes a control system.

First claim

What is claimed is:

1. A vapor distillation system, comprising:
a vapor distillation apparatus comprising:
a distillation chamber;
a heating element configured to vaporize a liquid within the distillation chamber;
a vent valve configured to modulate vapor release in response to temperature feedback from a control system for the distillation chamber; and
a temperature sensor configured to measure temperature within the distillation chamber, the temperature sensor being a thermocouple,
the control system comprising a vent controller configured to:
receive a temperature signal from the temperature sensor;
determine an operating state of the system; and
adjust a duty cycle of the vent valve based on the temperature signal received from the thermocouple and the operating state.

2. The vapor distillation system of claim 1 , wherein the duty cycle is adjusted to maintain temperature within a predetermined range.

3. The vapor distillation system of claim 1 , wherein the vent controller is further configured to have a feedback loop that automatically adjusts an output of the heating element based on the temperature signal received from the temperature sensor.

4. The vapor distillation system of claim 1 , wherein the control system includes at least one of the following states: startup, steady-state operation, and shutdown, and modulates venting accordingly.

5. The vapor distillation system of claim 1 , wherein the temperature sensor is positioned adjacent to the vent valve.

6. The vapor distillation system of claim 1 , wherein the control system further comprises a heating control system that adjusts the heating element in coordination with the vent controller to stabilize vapor production.

7. The vapor distillation system of claim 1 , wherein the control system further comprises a user interface for setting desired operational parameters.

8. The vapor distillation system of claim 1 , further comprising a pressure sensor, wherein the vent controller is configured to adjust the duty cycle based on pressure readings from the pressure sensor.

9. The vapor distillation system of claim 1 , wherein the vent controller utilizes a proportional-integral-derivative (PID) control algorithm to adjust the duty cycle.

10. The vapor distillation system of claim 1 , wherein the vent controller adjusts the duty cycle to prevent overheating in the distillation chamber.

11. The vapor distillation system of claim 1 , wherein the vent controller is configured to enter a low-power mode during periods of inactivity.

12. The vapor distillation system of claim 1 , wherein the vent controller adjusts the duty cycle to minimize noise during operation.

13. The vapor distillation system of claim 1 , further comprising an automated cleaning cycle triggered by the control system when specific operational thresholds are met.

14. The vapor distillation system of claim 1 , wherein the the duty cycle is adjusted based on a combination of temperature and humidity readings.

15. The vapor distillation system of claim 1 , wherein the vent controller is configured to interface with external control systems.

16. The vapor distillation system of claim 1 , further comprising:
an evaporator condenser apparatus comprising:
a substantially cylindrical housing; and
a plurality of tubes in the housing,

whereby a source fluid input is fluidly connected to the evaporator condenser and the evaporator condenser transforms source fluid into steam and transforms compressed steam into a product fluid output.

17. The vapor distillation system of claim 16 , further comprising:
a heat exchanger fluidly connected to the source fluid input and the product fluid output, the heat exchanger comprising:
an outer tube; and
at least one inner tube; and

a regenerative blower fluidly connected to the evaporator condenser, whereby the regenerative blower compresses steam, and whereby compressed steam flows to the evaporative condenser whereby compressed steam is transformed into the product fluid output.

18. The vapor distillation system of claim 17 , wherein the heat exchanger is disposed about the housing of the evaporator condenser.
