Description

Electric arc ionization reactor and a method for generating ozone by using air flow turbulence and water hammer

TECHNICAL FIELD:

BACKGROUND OF THE INVENTION:

Naturally, the existence of oxygen in the earth's atmosphere as a molecule consisting of two oxygen atoms causes two components, oxygen molecules when exposed to environmental conditions such as ultraviolet light or high temperature, and or strong electric fields and or free electrons and or radioactive emissions, by breaking the atomic bonds between two atoms consisting oxygen molecules, negative oxygen ions tend to merge with molecular oxygen and create three component ozone molecules.

Ozone molecule is highly active and due to negatively charged is highly capable of combining with materials and some of active fines. Exposure to ozone often causes to disjoint the outer membrane and the death of the microorgani. This matter caused ozone gas is known as one of the best disinfectants and antiseptics for water, air, food, surfaces and also objects and animals.

In the past, the production of ozone gas in industrial method was very laborious and inefficient. We can mention the plate reactor methods among the conventional methods of producing ozone gas. In this type of reactor, there are two parallel plates which discharge is done between them through a power source with very high potential difference and also a brief volumetric flow rate of fluid which can be the air and or pure oxygen gas, gas ionization process and consequently, the combination of negative oxygen ion and production of ozone gas is obvious. In another method, UV radiation, which has very high energy, can be used to ionize the oxygen gas. In this method, passing the air or oxygen gas fluid through the reactor, which equipped with UV-ray lamp causes to raise the level of kinetic energy and consequently, the separation of oxygen atoms.

In other methods, it is common to use corona needle and flat plates for ionization of oxygen.

Due to the concentration of electrons in sharp points, the possibilities of an electron jump from needle tip towards the plate is high and consequently, the useful life of the reactor can be more. Inventions such considered in the above-mentioned cases are as follows:

The inventions presented to the United States Patent and Trademark Office, No. US4383976A by Notaro Salvador P entitled "Ozone-generating assembly" is a device contains a large number of ozone generator tubes connect to the device through specific fittings which are easy to connect and assembly. This device contains ozone generator tubes in which there is a rod electrode connected to the first terminal of an electric current source. The tubes are covered by metal grid and connected to the second terminal of the power source. These tubes are embedded in sturdy containers which there are coatings on upper and lower part of them, and connected to an air or oxygen pressure source that has a number of outlets connected to a duct for discharging ozone.

And another invention No.US8440080 presents an ozone generating reactor, which is portable and designed in order to produce pure drinking water by using the ozone. The present invention offers a casing in which two electrodes consisting of an anode and a cathode continued from casing with water and each one has a rod or rod-like bar in contact with water. In this invention, There is a power source connected to the electrodes and created a potential difference between them, and at the same time, ozone is produced through the hydrolysis of water that causes to purify of water. The electrodes may be in shape of a plate or round or tube.

Another invention No. WO 2002064498 Al entitled Ozone Production from Co 2, a method presented for producing the ozone by discharging of 20KV alternating current with a frequency between 50 to 3000 hertz attempted to produce ozone from carbon dioxide gas in method of corona discharge.

The next invention, No. US 4123664, offers a tool for producing ozone in which it is possible to create electric arc and producing ozone between two electrodes by using of triangular waveform in potential difference and the cycle of charging and discharging the capacitor.

Among the problems of the above-mentioned, we can point to very low efficiency of the discussed methods as well as producing of inadvertent materials such as nitroglycerin and other possibly waste that are very dangerous and in some cases cause explosion.

DESCRIPTION:

The present invention is a method and mean for producing of ozone gas, and if using of air fluid by passing the gas into condensate dryer which using the cycle of refrigeration package through the circulation of Freon gas or any other known gas used for this cycle. Entering air after hitting the Hitex of dryer changers, if along with humidity, due to creating of condensation in the humidity, almost loose all of its humidity and enter into the next stage. At this stage, by passing the air through the physical filters, any remaining dust will be isolated then dry and clean air will be entered to the inlet nozzle of the reactor. The Reactor of the present invention has encapsulated form which the shell at the entrance and outlet is hemisphere shape. The middle of beginning and end hemisphere has a cylindrical shape and the reactor has at least one and or two outlets. The inside shape of the reactor is designed in a way that the bumps and dents are similar to the inside part of the gun barrel that is called "screw thread" in this text.the Output fluid from the nozzle due to the special shape of the nozzle which has deviated angle from longitudinal symmetry line makes a turbulent flow when exiting from nozzle tip, by dealing to the blades in the nozzle tip, maximum turbulence in the fluid movement path is occurring. Now dealing the current to the screwthreads inside of the reactor, rotating of the air or fluid have been reached to its maximum level and heavily tended to create a turbulent flow clockwise. Because of special design of this reactor for raising turbulence in the air and maximum time of retention (retention of fluid in the reactor), the screw threads inside of the reactor from the end part of one third of the reactor changes direction by an angle 90 degree and completely in the sharp shape and continues to rotate toward the end of the reactor. Changing direction of the screw threads inside of the reactor makes a shift change in the direction of passing fluid and fluid return because of hitting to the end of reactor and the outlet is too small makes the pressure raised at the end of reactor, as well as, reflected fluid because of impact in return path is dealt to passing fluid and maximum of turbulence which increase the microscopic instant pressure and a water hammer phenomenon or Shockwave along with creating fast, short-lived and damped waves by the returned fluid flow and intermittent pulse of the pressure source diaphragm engine caused increasing the instant pressure in the return intersection of screw threads.

The Water-hammer as well as turbulence causes increased the chance of encountering and dealing of charged ions and oxygen molecules to parts of associated with ionization which decreases the volume, size and length of the reactor and "pressure source" of a diaphragm pump. At the end, direct outlet along the reactor as well as the deviation one or two outputs which located at an acute angle from the central line makes the separation of producing ozone gas from an air mixture easier.

In the body of reactor, there are two series of needle electrodes made of tunxten in a certain distance from each other. Each series of mentioned electrodes includes two electrodes which located opposite each other. Each of four electrodes is located on one page. However, we can consider crossing page from each two groups of positive and negative electrode facing each other with respect to the second series by a different angle. In this case, because of approaching anode electrode of one series to cathode electrode of the second series, it is possible to create the eclectic arc between anode and cathode of two different series that in this condition to keep the efficiency of the reactor we should consider more distance in design of reactor between the electrode groups. If needed, we can increase the length of the reactor and the number of the oppositely the electrode groups for enhancing the efficiency. In the vicinity of each of the electrode groups which are responsible for making the arc to ionize oxygen gas, there is a bright source made of SMD and or any other light source can make a cone-shaped beam on area of electric arc, thus, photons of light make hertz effect (photoelectric effect) and electron after absorbing the energy of an electromagnetic beam such as x-rays or visible light, is emitted from the material. This phenomenon helps to increase the ionization of oxygen molecule percentage.

According to the above phenomenon, when dispersed static electricity, exposed plate light in the reactor vessel, attracted to each other and more concentrated in that environment and facilitate the arc movement in the entire surface of a vessel around the two electrodes, and by exposing to 12-15 kv current consequently the phenomenon of Pair production is occurring and effects on the ionization indirectly.

The reactor can be made of materials such as polymer and or glass and or composite and or any other insulation material as well as capable of resistant to internal temperature of the reactor. Due to being good insulating as well as having a flat surface, and the qualified formability when semi-molten, glass can be the best choice. The shape of the reactor is bivalve and two symmetric half cylinders sticking to each other during assembly and it provides the perfect shape of the reactor.

In the event of increasing of the length of designing the reactor, we can change the shape of the reactor from a direct form into a curved type, through a plurality of electric arc units. Regarding the high pressure inside the reactor, a two-piece aluminum cover in the form of two shells are surrounded the reactor from two sides, and regarding outlets of reactor as well as locating place of electrodes of the reactor on the sides, some half cylinders are considered for locating part of reactor's electrodes on each valve which can play the role of dissipating the heat "heat sink" in the reactor. The induction electric and magnetic field around the part out of the reactor can cause deviate the negative charged ozone molecules towards the positive electrode or pole.

This deviation of center causes ozone density reaches to the maximum in the outlet side of positive electrode. As the potential difference between electrodes can be a clear amount and be able to be controlled, so we can expect that the resulting force only acts within the limits of oxygen gas ionization and prevents the ionization of nitrogen molecules. As such, the possibility of ionization of possible nitrogen or sulfur in the fluid reaches to maximum and the amount of NOx and Sox is minimized. In the conventional reactors always capacitor chargeable and dischargeable power supplies are used for producing the ozone which due to the sawtooth shape of charging and discharging of capacitor we should expect to create corona discharging with different potency and not to be controlled in terms of power and direction of electron mutation, but in the present invention by using of alternating electric source and creating stable electric arc we can adjust intensity and potency of creating arc in a way that maximum of creating energy for oxygen ionization is less than used energy for nitrogen ionization.The Outlet of ozonizer reactor enters into the coil-like duct made of anti corrosion stainless steel, rotation of output fluid which has negative oxygen ions as well as oxygen molecules other than ozone gas causes most of negative ions hit oxygen and produce more ozone. Also by reducing the number of free ions, the amount of undesirable corrosion or oxidation of the final product is minimized, which, if not to combine with the moist mucous membranes of the body reduces malodor of ozone and irritation. Since the invention produces ozone by at least a high amount of required electricity we can utilize it as the economical ozonizer.

The air fluid and pure oxygen gas can be used as input raw material. The dryer can be any type of mechanical and or chemical dryer. The dryer can be a cycle type of refrigeration pack by using Freon gas and it cools the entering air and condenses the moisture of the air by a heat exchanger. Before entering the reactor, the entering air is purified by physical filters and dust as well as possible additional particles are separated. After passing through the filter, the purified air enters into the rotating nozzle of the reactor and then enters into the reactor in the way of rotating due to the positioning of the blade in front of the nozzle. The Nozzle can be made of metal or non-metal material. The reactor should be made of insulating material and an unbreakable glass type can be chosen. Silicon adhesives can be used in order to stick two pieces of the reactor. There are some bumps and dents in the form of the inside screw thread in the reactor internal part.

After travelling the two-thirds of the reactor length, the direction of the screw thread in the reactor is reversed to an angle of 90 degrees and proceeded in the opposite of its initial rotation direction to the end. At least a pair of electrode made of tunxten and or any resistant and strong material is embedded for creating the electric arc.

The number of electrode pairs can be two or more. Its power source can produce alternating current with high voltage; therefore, it is possible to create the electric arc between the electrodes. Putting the electric field at the bottom of the reactor can be helped to the deviation of ozone molecules as well as oxygen negative ions. The reactor has an encapsulated form. The diversion outlet at the bottom of the reactor facilitates the outflowing process of the negative ions which generated in the magnetic field.
