Water vapor distillation apparatus, method and system

A water vapor distillation system comprising:

• a water vapor distillation apparatus comprising:
• a source fluid input;
• an evaporator condenser apparatus comprising:
• a 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:
• an outer tube;
• and
• at least one inner tube;
• a regenerative blower fluidly connected to said evaporator condenser, whereby said regenerative blower compresses steam, and whereby the compressed steam flows to the evaporative condenser where compressed steam is transformed into product fluid;
• and
• a control system for controlling said fluid vapor distillation apparatus comprising:
• a blow down controller programmed to control a blow down valve;
• a source flow controller programmed to control a source flow valve;
• and
• a blow down level sensor in communication with a blow down controller and a source flow controller, said blow down level sensor sends signals related to said blow down level to said blow down controller and said source flow controller indicative of said blow down level,
• wherein said source flow controller is programmed to actuate said source flow valve based at least on said blow down level sensor signals, and
• wherein said blow down controller is programmed to actuate said blow down valve based at least on said blow down level sensor signals,
• whereby said blow down level and said source flow are maintained using said blow down level sensor signals as input;
• and
• a Stirling engine electrically connected to said water vapor distillation apparatus, wherein said Stirling engine at least partially powers said water vapor distillation apparatus, the Stirling engine comprising:
• at least one rocking drive mechanism comprising:
• a rocking beam having a rocker pivot;
• at least one cylinder;
• at least one piston, the piston housed within a respective cylinder whereby the piston is capable of substantially linearly reciprocating within the respective cylinder;
• and
• at least one coupling assembly having a proximal end and a distal end, the proximal end being connected to the piston and the distal end being connected to the rocking beam by an end pivot, whereby linear motion of the piston is converted to rotary motion of the rocking beam;
• a crankcase housing the rocking beam and housing a first portion of the coupling assembly;
• a crankshaft coupled to the rocking beam by way of a connecting rod, whereby the rotary motion of the rocking beam is transferred to the crankshaft;
• a working space housing the at least one cylinder, the at least one piston and a second portion of the coupling assembly;
• and
• a seal for sealing the workspace from the crankcase.
