Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, FIGS. 1 to 3.

Reference numeral 1 denotes an ion accelerator tube serving as a passage through which the fluid to be treated is introduced and transported.

The ion acceleration tube (1) is formed in a circular ring shape as shown in Figures 2 and 3 is formed on the inlet tube (8) for introducing the fluid on one side and the ion acceleration tube (1) on the other side A discharge tube 9 is formed for passing the atomized fluid through the actual fluid processor as it passes.

The conical plasma generating electrode 2 is formed on the inlet tube 8 side of the ion acceleration tube 1.

The plasma generating electrode 2 is electromagnetically discharged between the fixed electrode 21 by the voltage supplied from the power supply unit 6 to decompose the fluid flowing into the ion acceleration tube 1 into an ion state so that plasma ions are generated. do.

In addition, the voltage supplied to the plasma generating electrode 2 is varied according to the type of fluid flowing into the ion acceleration tube 1, and as the flow rate of the fluid flowing into the ion acceleration tube 1 increases, the fixed electrode ( The gap between 21 and the plasma generating electrode 2 is provided narrowly.

On the other hand, inside the ion acceleration tube 1, a plurality of collector electrode plates 3 are provided in which plasma current decomposed from the fluid flows a plasma current so that the movement speed of the fluid ions is accelerated.

As shown in FIGS. 2 and 3, the collect electrode plate 3 is divided into N equal parts of the ion acceleration tube 1 as a whole, and is installed in a plurality of locations. The example in which the collector electrode plate 3 is provided is illustrated.

By connecting the variable resistors VR1 to VR3 capable of varying the resistance between the collector electrode plate 3 and the power supply unit 6, the resistances of the variable resistors VR1 to VR3 are varied. The current applied to the collect electrode plate 3 is varied. In the present invention, the ion acceleration tube is gradually increased so as to gradually increase the intensity of the current applied to the collect electrode plate 3 in the clockwise order from the inlet tube 8. The movement speed of the fluid ions present in (1) was gradually increased.

In addition, a toroidal coil 4 is formed in a plurality of places so as to surround the outer circumferential surface of the ion acceleration tube 1, and a coil body 7 is provided at one side of the core 5 penetrating the center of the ion acceleration tube 1. It is wound.

The toroidal coil 4 generates a magnetic field by the input current so that the plasma ions present in the ion acceleration tube 1 are in a stationary state, thereby improving the collision effect between the ions of the fluid and the plasma.

The core 5 and the coil body 7 serve to promote the generation of plasma current by electromagnetic induction.

That is, the fluid flowing into the ion acceleration tube 1 is decomposed into an ionic state by the electromagnetic discharge generated from the plasma generating electrode 2, thereby generating plasma ions, and the decomposed molecular ions of the fluid form the collect electrode plate. The movement speed is accelerated by the current in the plasma state transmitted from (3) to move inside the ion acceleration tube (1), and at this time, all around the inside of the ion acceleration tube (1) by the magnetic field generated by the toroidal coil (4) Plasma ions staying in and the fluid ions moving inside the ion acceleration tube 1 collide with each other to separate the fluid ions in an atomic state, thereby accelerating the ionization of the fluid.

As described above, if the fluid transferred to the ion ionization state while moving inside the ion acceleration tube 1 is discharged and treated through the discharge tube 9, the neutral fluid is transferred to the atomic ion state, thereby increasing the processing efficiency of the fluid. You can expect.

As described above, the principle of using plasma for fluid treatment is as follows.

In special circumstances, negatively charged electrons are separated from atoms or molecules and mixed in a chaotic state with positively charged ions.

This plasma is also referred to as the fourth material state following the solid, liquid and gas.

When air is ionized to create a plasma, a large amount of oxygen molecule ions are generated, which try to recombine by meeting electrons mixed in the plasma. However, this very bond is not an electrically neutral oxygen molecule but two oxygen atoms, and this phenomenon is called separation and recombination.

In other words, if the substance to be burned is around the freshly produced oxygen atoms, it will oxidize without delay, so if you make a lot of oxygen molecule plasma in the air, it will be well oxidized and clean without any fumes or unburned substances.

When the plasma is used as described above, the ionized fluid is cleanly processed when the solid, liquid, gas, and the like are treated in the present invention to process the fluid using the plasma.

In addition, reference numeral 11 denotes a flow sensor for detecting the flow rate of the fluid flowing into the ion acceleration tube 1, and the fixed electrode 21 and the plasma generating electrode according to the flow rate detected by the flow sensor 11 The interval in (2) is changed.

Reference numeral 22 denotes an ammeter for measuring the amount of current supplied to the collect electrode plate 3, and 23 denotes a voltmeter for measuring and displaying the voltage output from the power supply unit 6.

Referring to the operation of the present invention configured as described above is as follows.

When the fluid to be treated is introduced into the inlet tube 8, the fluid flowing into the inlet tube 8 is decomposed into an ion state by the electromagnetic discharge generated by the plasma generating electrode 2, thereby generating plasma ions. .

The generated plasma ions are stagnant in the state in which the ion ions are wound around the magnetic lines by the magnetic field generated by the toroidal coil 4, and are generated in the collector electrode plate 3. The fluid ion in the molecular state is accelerated in the ion acceleration tube 1 by the current in the plasma state.

Molecular fluid ions that move while being accelerated in the ion acceleration tube 1 are ionized in an atomic state while strongly colliding with plasma ions existing in a stationary state.

In other words, when the neutral fluid is ionized to form plasma ions, a large amount of fluid molecule ions are generated, and the fluid molecule ions generate plasma ions and a large amount of fluid molecule ions are generated. Ions try to recombine by meeting electrons mixed in plasma ions.

In this coupling, the fluid molecules are not electrically neutral fluid molecules but two fluid atoms. This phenomenon is called separation and recombination.

At this time, when the substance to be reacted is around the generated fluid atoms, oxidation occurs rapidly and the fluid molecules collide with the electrons in the plasma ions to be separated into oxygen atoms, but some become molecules of high energy state. Oxygen molecules in these excited energy states are rapidly reacted with other substances so that the fluid can be processed quickly.

As described above, when the ionized fluid in the atomic state is supplied to the reactor and treated, the fluid can be completely processed.

In order to process a larger amount of fluid, it is possible to form and process a plurality of ion acceleration tubes 1 of the present invention in parallel.

In the fluid treatment apparatus using the low temperature plasma of the present invention, since the ionized fluid is rapidly oxidized in the reactor, ozone generation, wastewater treatment, manure treatment, sewage treatment, tap water treatment, dyeing wastewater treatment, and non-degradable wastewater Fluids such as treatment, fuel activator, incinerator and air pollution purification can be processed.

As described above, the present invention includes an ion acceleration tube through which a fluid to be treated flows in and moves therein, and forms a plasma generating electrode for generating plasma ions by ionizing the fluid by electromagnetic discharge inside the ion acceleration tube. In addition, the ion accelerator tube is formed by forming a magnetic field in a plurality of places inside the ion accelerator tube and forming a collector electrode plate for flowing the current in the plasma state to accelerate the movement velocity of the fluid ions. The effect of providing a fluid treatment apparatus using a low temperature plasma in which molecular fluid ions collide with the plasma ions within the atomic ion state and is treated in the ion ion state to improve the processing efficiency of the fluid significantly.
