Abstract
An energy-saving method and system for distilling, desalinating or purifying water relating to a method of increasing the amount of heat recycled back into the system. The system involves powering a compressor using a series of expanders and the energy derived from each expander cumulatively powers the compressor. The compressor draws vapor from seawater contained in an evaporator and compresses it into a condenser. The heat given off by the condenser is absorbed by the evaporator and recycled back into the system.
Claims20
An energy recycling system comprising:
- a first evaporator containing in a first portion a first liquid having a first temperature which is at the first liquid's boiling point;
- a first conduit in which a first vapor of the first liquid received from the first evaporator is compressed by a compressor, thus causing the first vapor in the first conduit to have a second temperature, higher than the first temperature;
- a first expander configured to drive the compressor to compress the first vapor from the first evaporator into the first conduit,
- the first conduit having thermo-conductive properties and functioning as a first condenser,
- wherein the second temperature of the first vapor in the first conduit having a higher temperature than the first temperature, causing a heat transfer from the first vapor in the first conduit to the first liquid, and thus the boiling of the first liquid, when the first conduit passes through the first evaporator;
- wherein the first conduit containing a first fluid comprised of at least one member of the group consisting of the first vapor and a condensate of the first vapor passes through a second evaporator, at least a portion of the first vapor within the first conduit condenses into the condensate of the first vapor, and,
- wherein the first expander driven by a second vapor of a second fluid expands the second vapor contained by the second evaporator into a second condenser
- the second liquid having a third temperature which is at the second liquid's boiling point but is lower than the second temperature, such that boiling of the second liquid occurs, generating the second vapor, when the first conduit is passed from the first evaporator and passes through the second evaporator;
- wherein the third temperature is greater than a fourth temperature of the second vapor in the second condenser,
- further comprising a second conduit, having thermo-conductive properties, transporting the first liquid, having a fifth temperature lower than the fourth temperature, to the first evaporator after passing through the second condenser and absorbing therein heat from the second vapor, causing condensation of the second vapor,
- further a pump is provided for pumping the second liquid from the second condenser to the second evaporator.
