Definitions

  • the present invention relates to ion generators, and more particularly to bipolar ionization generators.
  • negative ion generators in which a high voltage is applied to at least one emitter, said emitter emitting electrons into the air are known, for example. These electrons ionize the particles present in the air triggering reactions which allow purifying the air.
  • ozone and other reactive oxygen species which react with bacteria and virus present in the air, and also with volatile organic substances, improving air quality, are also produced.
  • ozone also has negative effects on the human body, particularly in children, the elderly and people with heart problems and respiratory problems, with regulations in place restricting the concentration of ozone present in the air.
  • the electric potential applied to the emitter must be reduced in order to reduce the generated ozone, but this entails a reduction in ion generation.
  • Negative and positive ion generators which attempt to solve the problems caused by negative ion generators are also known.
  • the emitter of the ion generator By applying a high voltage to the positive and negative terminals of a power supply source of the ion generator, the emitter of the ion generator is capable of emitting positive and negative ions.
  • the electrons emitted into the air through the application of negative voltage generate negative ions.
  • the charge applied to the air through the generation of positive voltage generates positive ions.
  • the generated positive and negative ions are unstable, causing a series of ionic recombinations, separations and conversions reacting with water molecules in the air, among others, and ion clusters are formed. These ion clusters ultimately result in reactive species with high oxidative capacity both for chemical and biological elements present in the air. The air is therefore purified without generating contaminating elements.
  • Ion generation is proportional to the voltage value in the ion emitters.
  • the high voltage difference applied in ion generators produce the so-called corona effect in emitters comprising metallic tips for releasing electrons into the air.
  • This corona effect occurs due to the potential gradient in the electric field of the surfaces of said tips, changing the characteristics of the air surrounding same, converting them into conductive ions and generating plasma, and furthermore releasing large amounts of ozone, being able to create atmospheres with concentrations exceeding 0.05 ppm (parts per million).
  • Air molecules are ionized and can conduct electric current. If the geometry of the tip and the potential gradient are intense enough so as to ionize and cause dielectric breakdown of the air, it can reach another different lower-potential conductor, and a discharge resulting in an electric arc will be produced.
  • Document CN20526504 U describes a positive and negative ion generator for ionizing the air, comprising at least one emitter, the emitter comprising a conductive element and a plurality of conductive filaments electrically connected and fixed to the conductive element, each emitter comprising a support made with electrically insulating material holding the conductive element.
  • the object of the invention is to provide an ion generator, more particularly a bipolar ionization generator, as defined in the claims.
  • the ion generator of the invention describes a positive and negative ion generator for ionizing the air, comprising at least one emitter, the emitter comprising a conductive element and a plurality of conductive filaments electrically connected and fixed to the conductive element, each emitter comprising a support made with electrically insulating material holding the conductive element, said holding leaving the filaments free of movements.
  • Each emitter of the ion generator comprises a grounded mounting bracket made with conductive material, the mounting bracket holding the support, said support comprising at least one spacer element that is prolonged between the mounting bracket and the filaments forming a barrier to prevent electric arcs between said mounting bracket and said filaments.
  • the generation of positive and negative ions with emitters comprising filaments requires the application of high voltages, ionizing the air and converting it into an electrical conductor.
  • the geometry of the filaments and a high potential gradient in said filaments can cause dielectric breakdown of the air, reaching a different lower-potential conductor, such as the mounting bracket, a discharge resulting in an electric arc being produced. This situation occurs because given that since the filaments have freedom of movements, they move closer to lower-potential conductive parts, due to airflow or due to the differences in applied voltage.
  • the emitter of the ion generator of the invention comprises the insulating support, which prevents possible unwanted electric discharges, with a spacer element forming a barrier between the filaments in motion and the mounting bracket.
  • the object of the invention is to generate the largest amount of primary ions and to have the largest possible air volume coming into contact with said primary ions, and to thereby purify the air, but without generating, or generating the smallest possible amount of, compounds that are particularly harmful to health, such as ozone, for example, without posing any safety issues, for example electric arcs, for users either.
  • air is mainly formed by nitrogen N (about 78%) and oxygen O (about 21%), with a water percentage of about 0.97%.
  • N2+, O2+, N+, and O+ are generated, which are quickly converted to protonated hydrates H+, (H2O)n, for n ⁇ 10, due to their capacity to attract water.
  • free electrons bind rapidly to oxygen molecules to form radical superoxide 302-.
  • ion clusters These species are referred to as ion clusters. These ion clusters ultimately result in reactive species with a high oxidative capacity both for chemical and biological elements present in the air. The air is thereby purified without generating contaminating elements.
  • ammonia NH3 for example, it breaks down into N and H, converting a potentially hazardous contaminant into a natural compound present in the air.
  • Figure 1 shows a perspective view of an embodiment of a linear emitter 10.
  • Figure 2 shows a front view of the linear emitter 10 of the Figure 1 .
  • Figure 3a shows a front schematic view of an embodiment of a T-shaped linear-type ion generator 200 of the invention, with a positive emitter 10 and a negative emitter 10, comprising a single mounting bracket 15 and a DC power supply source 100 supported on said mounting bracket 15.
  • Figure 3b shows a front schematic longitudinal section view of the ion generator 200 of Figure 3a , showing the positive terminal 110 and the negative terminal 120 of the power supply source 100 electrically connected, respectively, to a conductive element 12 of the positive emitter 10 and of the negative emitter 11.
  • the ion generator 200 of the invention comprises a high-voltage DC power supply source 100, for example, not less than 1.5 KV (kilovolts), and up to 15 KV, of both a positive voltage V+ and a negative voltage V-, and preferably between 5 KV and 7 KV.
  • the DC power supply source 100 sends voltage pulses.
  • the power supply source 100 comprises a positive terminal 110 where the positive voltage V+ is applied, and a negative terminal 120 where the negative voltage V- is applied. Said positive and negative terminals 110, 120 are electrically connected to a positive emitter 10 and to a negative emitter 11, respectively.
  • Each of the positive and negative emitters 10, 11 comprises a conductive element 12 electrically connected to the positive terminal 110 and to the negative terminal 120 of the power supply source 100 by means of a conductive wire, the conductive element 12 in this embodiment being a longitudinal elongated plate made with a conductive material, preferably a metallic conductive material.
  • the positive and negative emitters 10, 11 also comprise a plurality of conductive filaments 13, electrically connected and fixed to each conductive element 12.
  • the power supply source 100 is a high-voltage AC power supply source (not shown in the drawings), an alternating voltage being applied to a single emitter between the positive terminal 110 and the negative terminal 120, this alternating voltage being a sine wave, for example, alternatingly supplying positive voltage V+ and negative voltage V- to said emitter.
  • the voltage can be changed in each terminal simultaneously depending on wave amplitude.
  • the filaments 13 are thin fibers with a thickness equal to or less than 0.2 millimeters (mm) in diameter, and the number thereof is always equal to or more than five hundred, in this embodiment of the ion generator 200 the number being a few thousand per conductive element 12.
  • the filaments 13 are attached to the conductive element 12 on one of the sides thereof, being fixed by different methods, screwing, clamping, etc., maintaining electrical connection with the conductive element 12.
  • the filaments 13 are always arranged projecting transversely with respect to the length of the conductive element 12, and they therefore have freedom of movements when exposed to an airflow or subjected to high electrical voltages.
  • filaments 13 are formed by a non-conductive or less conductive substrate, such as, for example, cotton, polyester, nylon, or stainless steel for high-performance ionization fibers, such as aramids, high-density polyethylene, polymers such as PBI, PBO or PTFE, carbon nanotubes or other materials having similar characteristics.
  • Said substrate is coated or integrated with conductive elements such as nickel, copper, gold, silver or titanium. Since they have such a small diameter, the very high number of filaments 13 amounting to thousands can be positioned very close together in the small space of the conductive element 12.
  • the voltage of each terminal 110, 120 of the power supply source 100 is applied to the filaments 13.
  • a voltage difference ⁇ V such as the voltage difference between the positive voltage V+ of the positive terminal 110 and the negative voltage V- of the negative terminal
  • the generated voltage difference ⁇ V is 10 KV.
  • An electric field gradient is generated in said filaments 13, and it must be taken into account that said electric field gradient increases in a manner inversely proportional to the diameter of the filaments 13, which allows said filaments 13 to act as independent ion generators by releasing electrons into the air, the positive emitter 10 and the negative emitter 11 simultaneously emitting positive and negative ions, respectively.
  • a high concentration of ionizing tips is therefore obtained with the filaments 13 in a small space, generating a very high ion density.
  • the corona effect can occur if the voltage of application is very high, which effect can lead to the generation of a large amount of harmful ozone or nitrogen oxides.
  • the probability of this corona effect occurring increases in a manner that is inversely proportional to the diameter of the filaments 13.
  • the probability of ozone and nitrogen oxides occurring also varies depending on the material subjected to the mentioned electric field gradient. The material described above with which the filaments 13 are formed, minimizes the occurrence of said compounds in the ion generator 200 of the invention.
  • Each positive and negative emitter 10, 11 comprises a support 14 made with electrically insulating material holding the conductive element 12, and preventing the user from receiving possible unwanted electric discharges.
  • the support 14 has a general U shape, comprising a housing 20 where the linear conductive element 12 is housed.
  • Said housing 20 comprises an inner space 18 and a groove 17.
  • the inner space 18 is arranged in the lower portion of the U, and the groove 17, which is narrower than the inner space 18, communicates with the inner space 18 through an end, and is open at the other end thereof with the upper portion of the U.
  • the conductive element 12 with the mounted filaments 13 is introduced from a side opening of the support 14 towards the housing 20, the conductive element 12 abutting with the lower portion of the inner space 18 of the housing 20, the conductive element 12 being held laterally in the groove 17.
  • the filaments 13 are therefore free of movements substantially above the central groove 17.
  • the inner space 18 allows making it easier to place the conductive element 12, as well as to mass produce the emitter 10, 11 by allowing the installation and laying out of cables therein, for example.
  • Each positive and negative emitter 10, 11 also comprises a grounded mounting bracket 15 made with conductive material, the mounting bracket 15 holding the support 14. Since the support 14 is made of an insulating material, for example, a plastic, static charges which may cause problems in the operation of the ion generator 200, or even become a nuisance, and furthermore hazardous for the user, can be generated, so grounding the mounting bracket 15 solves this problem.
  • the mounting bracket 15 has a U shape and surrounds the support 14 in its lower side portion and in its lower portion, the support 14 fitting in the mounting bracket 15, being retained therein. The central and upper side portions of the support 14 are therefore free.
  • the emitter 10, 11 Since it is subjected to a high electrical voltage, the emitter 10, 11 causes the filaments 13 to separate from one another taking up more space, an issue that may be compounded if the emitter is within an airflow.
  • the use of high voltages for generating positive and negative ions with emitters comprising filaments ionizes the air and converts it into an electrical conductor.
  • the geometry of the filaments and a high potential gradient in said filaments can cause dielectric breakdown of the air, reaching another different conductor, such as the lower-potential mounting bracket 15, a discharge resulting in an electric arc being produced.
  • the support 14 has sides around the conductive element 12 with the mounted filaments 13 raised, comprising in the upper and side portions thereof a spacer element 16 on each side of the filaments 13.
  • the spacer element 16 is an integral part thereof, being made by extrusion at the same time as the support 14. In other embodiments, the spacer element 16 is a separate part with respect to the support 14 but attached thereto.
  • the two spacer elements 16 have a U shape or open vessel shape and are arranged on the sides of the support 14, in the upper portion, partially surrounding the filaments 13, with a semicircular-shaped interior, on the side close to the filaments 13, an arrangement which allows free movement of said filaments 13.
  • the spacer elements 16 therefore space the filaments 13 in the air from the mounting bracket 15, preventing electric arcs from being formed when the power supply source 100 applies the voltage difference ⁇ V, and the potential gradient generated in the filaments 13 is intense enough to cause dielectric breakdown of the air.
  • FIGS 3a and 3b show an embodiment of a T-shaped linear-type ion generator 200 with a linear positive emitter 10 and a linear negative emitter 10.
  • This ion generator 200 comprises a single mounting bracket 15 acquiring a T shape, and a DC power supply source 100 supported on said mounting bracket 15.
  • a support 14 holding a conductive element 12 with the mounted and fixed filaments 13 is arranged inside the single mounting bracket 15, on each side of the T, forming the positive emitter 10 and the negative emitter 11.
  • the positive terminal 110 and the negative terminal 120 of the power supply source 100 are electrically connected, respectively, to the conductive element 12 of the positive emitter 10 and of the negative emitter 11, by means of a conductive wire.
  • the power supply source 100 is arranged inside the same mounting bracket 15 between the positive emitter 10 and the negative emitter 11.

  • the number of supports 14 with their conductive element 12 and filaments 13 is different for the positive emitter 10 and the negative emitter 11. A different number of ions are thereby generated from both emitters according to the interest in each installation made.
  • Ion generators 200 with linear-type positive and negative emitters 10, 11 can also be made with a mounting bracket 15 having a modular structure (not shown in the drawings).
  • This modular mounting bracket 15 has elements on the sides which allow attaching different emitters 10, 11 between mounting brackets 15, such that a plurality of emitters 10, 11 can be arranged parallel to one another.
  • the number of attached positive emitters 10 and the number of attached negative emitters 11 can be different, a different number of ions being generated from both emitters according to the interest in each installation made.
  • the electrical conductivity of compounds present in the air which are subjected to a high voltage level can change.
  • Ambient humidity can favor air conductivity in a manner inversely proportional to voltage, i.e., the higher the humidity, the less voltage is required to produce this effect.
  • This effect increases ozone generation and causes a voltage drop which reduces ion generation.
  • the distance d separating the ends of both emitters 10, 11 assures that this problem does not arise.
  • This distance d is proportional to the voltage difference ⁇ V between the positive terminal 110 and the negative terminal 120 of the power supply source 100.
  • the distance d is the smallest distance between elements in voltage, i.e., the distance between filaments 13 in the embodiment that is shown.

  • the airflow sensor 150 assures the operation of the air conditioning system 400 provided that there is the airflow 20 in the conduit 30 due to the operation of the air conditioning system 400. Energy consumption is thereby optimized by operating the ion generator 200 only when needed. In no case does the ion generator 200 exceed the ozone level established by law. By using the airflow sensor 150 and disconnecting the ion generator 200, possible ozone concentrations are even further minimized since there is no air circulation.
  • the configuration of the support 14 of the positive and negative ion emitters 10, 11, with the spacer element 16, will help to prevent electric arcs from being produced between the filaments 13 and the metallic mounting bracket 15 when, either in a predetermined manner, or depending on the air quality detected in the area to be ionized, the voltages V+ and V- applied in the terminals 110, 120 of the power supply source 100 are high.
