Abstract

A hydromagnetic desalination cell including at least one hollow rectangular flow conduit, a first rectangular magnet and a second rectangular magnet each having a north pole face and a south pole face opposite of each other, wherein the first and second rectangular magnets are disposed along a longitudinal axis and on opposite sides of the rectangular flow conduit, a first opening and a second opening on opposite walls of the rectangular flow conduit extending between the first and second rectangular magnets, and a first and second chamber fluidly connected to the first and second openings. A hydromagnetic desalination system and methods of desalinating brine water with the hydromagnetic desalination system are also disclosed.

First claim

The invention claimed is:

1. A hydromagnetic desalination cell, comprising:
a plurality of stacked hollow rectangular flow conduits with each conduit having a conduit inlet on a first end and a conduit outlet on a second end, wherein the hollow rectangular flow conduits are made of a non-magnetic and non-conductive material;
a first rectangular magnet and a second rectangular magnet each having a north pole face and a south pole face opposite of each other,
wherein the first rectangular magnet and the second rectangular magnet are independently selected from the group consisting of a neodymium iron boride magnet and a samarium cobalt magnet,
wherein the first and second rectangular magnets are disposed along a longitudinal axis and on opposite sides of the stacked rectangular flow conduits such that the north pole face of the first rectangular magnet contacts a first face of the stacked rectangular flow conduits and the south pole face of the second rectangular magnet contacts a second face of the stacked rectangular flow conduits, and the first and the second rectangular magnets provide a magnetic field that extends between the magnets;
a first opening and a second opening on opposite walls of the stacked rectangular flow conduits extending between the first and second rectangular magnets;
a first chamber fluidly connected to the first opening of the stacked rectangular flow conduits;
a second chamber fluidly connected to the second opening of the stacked rectangular flow conduits;
a positive electrode connected to the first chamber; and
a negative electrode connected to the second chamber;
wherein the first and second rectangular magnets generate a magnetic field that causes cations to flow from the first opening of the stacked rectangular flow conduits to the first chamber, and anions to flow from the second opening of the stacked rectangular flow conduits to the second chamber.

2. The hydromagnetic desalination cell of claim 1 , wherein a distance between the north pole face of the first rectangular magnet and the south pole face of the second rectangular magnet ranges from 0.01-0.035 m.

3. The hydromagnetic desalination cell of claim 1 , wherein the stacked hollow rectangular flow conduits have a rectangular cross section with a width dimension that is larger than a height dimension.

4. The hydromagnetic desalination cell of claim 1 , wherein the non-magnetic and non-conducting material is polyvinyl chloride.

5. The hydromagnetic desalination cell of claim 1 , wherein the thickness of the first and second rectangular magnets are the same, and a distance between each stacked hollow rectangular flow conduit is equal to the thickness of the first and second rectangular magnet.

6. The hydromagnetic desalination cell of claim 5 , wherein the thickness of the first and second rectangular magnet ranges from 1-6 cm.

7. The hydromagnetic desalination cell of claim 1 , wherein the first and second rectangular magnets provide a magnetic field strength of 0.3 to 0.6 Tesla in the center of the rectangular flow.

8. The hydromagnetic desalination cell of claim 1 , wherein the first and second rectangular magnets provide a magnetic field strength of 0.34 to 0.46 Tesla in the center of the rectangular flow.
