Abstract

By using a gas turbine and a closed cycle gas/(air or nitrogen) turbine in a cascaded manner, the heat required by the heat exchanger chambers (for heat addition) in the closed cycle gas turbine can be obtained by using the heat transferred from the exhaust gas of the open cycle gas turbine. Instead of an open cycle gas turbine, we can also obtain heat from a nuclear power plant, if any. When we send very hot air to the heat exchanger compartment (for cooling air) after leaving the turbine from the closed cycle gas/air turbine, we use seawater in multiple heat exchangers to cool the air and use the heat to desalinate the seawater, so finally we can produce both fresh water and electricity through both open and closed gas turbines.

Description

Cogeneration turbine for power generation and seawater desalination
Background
There are several inventions relating to desalination of sea water. All of these inventions focus on extracting heat from the sun (solar energy). These inventions do not produce a large amount of fresh water and cannot stably supply energy due to the limited time of the heat source (influence of night and cloudy day).
In my invention, it is proposed to use an open cycle gas turbine as the heat source and present it to a closed cycle gas/air turbine which requires heat from one stage of the closed cycle (heat exchangers B2, B3).
After leaving the turbine (B4), the very hot air needs to be cooled before entering the compressor (B1). This is typically accomplished by the gas flow in the second heat exchanger.
I propose to desalinate seawater by passing it through a number of heat exchangers (B6, B7, B8) and to cool the closed-cycle air before it enters the compressor (B1).
In this way, the cogeneration of open and closed cycle gas turbines can generate electricity together, and the closed cycle turbine can produce fresh water from seawater at the same time.
I have added a method of combining solar heat with heat from an open cycle gas turbine, the combined heat being used as a secondary heat source in the heat exchanger of (B3), which can save some energy for the open cycle gas turbine.
Detailed Description
In an open cycle gas turbine (a), air enters the compressor (a1), then enters the combustion chamber (a2), and then the very hot, high pressure gas from (a2) impinges on the turbine (A3), which leaves the turbine as a very hot exhaust gas.
These gases enter the first heat exchanger (B2) and lead to iron pipes which are divided in the heat exchange chamber into 2, 3 or more pipes, each pipe being surrounded by a layer of insulation.
The multiple conduits leave the chamber and become one conduit again, going to (B3).
Warm compressed air (or nitrogen) entering the chamber (B2) from (B3) is directed to the copper tube divided within the chamber to the coil within one of the iron tubes. The coil should be in the middle of the iron pipe and not touch the pipe wall.
At the end of the tube, the coils are again connected to form a tube, B2, and very hot compressed air enters the turbine (B4).
Air and very hot gases move in opposite directions to each other.
In chamber (B3), its design is similar to chamber (B2), except that in the copper tube as compressed warm or hot air from compressor (B1) to (B3) and out (B2) air, part of the hot gas enters the middle of each tube of chamber (B3) from the copper coil of (B2), exits from the other side, reconnects to one tube and enters the exhaust.
There is no direct insulation on the pipe, but a material that can be made very hot by solar heat is installed and transferred to the pipe where the air flows. These materials may be (lava rock or coal).
The outer wall of the chamber is made of glass on the top and both sides so that sunlight is absorbed in the morning and introduced into the chamber through the mirrors. These glass panels can be covered with insulating material after the sun has fallen on the hill until the sun rises again. The bottom of the chamber is made of iron and has a support for the pipe which has supports for the coils inside, as shown in (B3).
After the air leaves the turbine (B4), it enters a multi-pass heat exchanger for cooling, absorbing (B6, B8) the heat in the air with seawater, and the cold air enters the compressor (B1), starting the cycle again.
As shown, the chamber (B6) has multiple sets of coils, passing the very hot air obtained (B4) to several coils of the chamber (B6) and exiting from one of the formed tubes, passing the warm air in (B8).
The pipes feed the partially warm seawater from (B8) to several atomizers on the wall of the chamber (B6) atomizing the water into droplets which drop on top of several sets of pipes with hot air in the pipes in the chamber.
Most of the water droplets evaporate by absorbing heat from the air in the duct and evaporate in the form of gas, rise to the curved roof of the chamber (B6) and are directed by the suction fan to the duct out of the chamber (B7). The remaining water droplets fall, collect at the bottom of (B6) and rejoin the atomizer with warm water from (B7 and B8) via the water droplets leading to the pipe.
In chamber (B8), there is a coil set immersed in seawater, which completely fills the chamber (B8) and is driven from the sea by a water pump to enter the chamber from the bottom, exit from the top of the chamber after warming, and extract the rest of the heat in the air before entering (B6). The air leaving the chamber cools, entering the compressor (B1).
In (B7), the hot water vapor enters the chamber in the form of a gas from the sidewall above the level of the fresh water formed. The hot gas rises from several sets of pipes horizontally suspended in the chamber and is directly fed into the seawater under the push of a water pump.
The warm sea water after the exchange of heat leaves the chamber in a pipe (B7) and the water vapour cools during its rise, causing a large amount of water vapour to condense, falling under gravity into the bottom of the chamber, becoming fresh water and being pumped out.
The remaining steam exits the pipes at the top side of the chamber, enters the hot water steam pipe, and enters the chamber again for repeated circulation.
