Abstract
A water vending apparatus is disclosed. The water vending system includes a water vapor distillation apparatus and a dispensing device. The dispensing device is in fluid communication with the fluid vapor distillation apparatus and the product water from the fluid vapor distillation apparatus is dispensed by the dispensing device.
Claims22
A water vending system comprising:
- a water vapor distillation apparatus comprising:
- a source water input;
- an evaporator condenser apparatus comprising:
- a substantially cylindrical housing;
- and
- a plurality of tubes in the housing,
- whereby the source water input is fluidly connected to the evaporator condenser and the evaporator condenser transforms source water into steam and transforms compressed steam into product water;
- a heat exchanger fluidly connected to the source water input and a product water 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 the compressed steam flows to the evaporative condenser where compressed steam is transformed into product water;
- and
- a dispensing device, wherein the dispensing device is in fluid communication with the fluid vapor distillation apparatus and whereby product water from the fluid vapor distillation apparatus is dispensed by the dispensing device.
