Abstract

A plasma reactor for enriching water with nitrogen compounds. The plasma reactor includes a water container (8); a plasma head (3) connected with a microwave generator (1) by a waveguide (2); a quartz tube (5) having a first end situated within the plasma head (3) and a second end that protrudes into the water container (8); a gas circulator (9) configured to introduce gas into the first end of the quartz tube (5) so that the introduced gas comes out through the second end of the quartz tube (5); a discharge generating rod (4) configured to be inserted into the plasma head (3) within the quartz tube (5) to generate a discharge in the quartz tube (5) and to be moved out of the head (3) after the discharge has been generated.

Claims

1. A plasma reactor for enriching water with nitrogen compounds comprising:

a water container;

a plasma head connected with a microwave generator by a waveguide;

a quartz tube having a first end situated within the plasma head and a second end that protrudes into the water container;

wherein the second end of the quartz tube has an outlet and is positioned so that upon providing water for enriching to the water container, at least the outlet is submersed in water;

a gas circulator configured to introduce gas into the first end of the quartz tube so that the introduced gas comes out through the second end of the quartz tube;

a discharge generating rod configured to be inserted into the plasma head within the quartz tube to generate a discharge in the quartz tube and to be moved out of the head after the discharge has been generated;

wherein the discharge is effected in the quartz tube in a microwave field supplied through the waveguide from the microwave generator, so that the gas passing through the quartz tube is ionized in a plasma discharge; and

wherein the outlet comprises plurality of holes, so that when the gas leaves the second end of the quartz tube, it is released in form of gas bubbles.

2. The plasma reactor according to claim 1, wherein the gas circulator is adapted to draw gas from above the water surface in the water container when provided with water for enriching and to direct this gas to the first end of the quartz tube.

3. The plasma reactor according to claim 1, further comprising a vibration generator with a vibration conducting element protruding into the water container.

4. The plasma reactor according to claim 3, wherein the vibration generator is an ultrasonic vibration generator.

5. The plasma reactor according to claim 1, wherein the outlet has a plate-like shape.

6. The plasma reactor according to claim 1, wherein the quartz tube, after providing water to be enriched, is submersed at least 30 cm in water.

7. The plasma reactor according to claim 1, wherein the holes have a diameter below 1 mm.

8. The plasma reactor according to claim 1, wherein the holes have a diameter below 0.5 mm.

9. A method for enriching water with nitrogen compounds, comprising the steps of:

providing a water container;

providing a plasma head connected with a microwave generator by a waveguide;

providing a quartz tube having a first end situated within the plasma head and a second end that protrudes into the water container;

providing water for enriching to the water container in an amount such that an outlet at the second end of the quartz tube is submersed in water;

introducing, by a gas circulator, gas into the first end of the quartz tube so that the introduced gas comes out through the second end of the quartz tube, wherein the outlet comprises plurality of holes so that when the gas leaves the second end of the quartz tube it is released in form of gas bubbles;

inserting a discharge generating rod into the plasma head within the quartz tube;

supplying to the quartz tube, through the waveguide from the microwave generator, a microwave field;

generating a discharge in the quartz tube, so that the gas passing through the quartz tube is ionized in a plasma discharge; and

removing the discharge generating rod from the plasma head after the discharge has been generated.
