Abstract

An air filter assembly includes an ion source positioned adjacent to the front face of an air filter to inject ions into the arriving air flow. The ions penetrate upstream sufficiently far to have ionized the air and charge particles before their arrival at the filer trapping medium. The ion source is preferably sufficiently thin as to allow the filter with the ion source mounted thereon to be inserted into a filter slot in a duct of an air handling unit.

Description of the invention () The present invention relates to air filters, in particular, to the efficiency of an air filter by applying The dust particles carried in the air are ionized and strengthened before entering a supplementary filter pad. Ionization has long been used to enhance the removal of particulate matter from the air. In U.S. Patent No. 945917 previously issued to Cotterel 丨 (1910), the air containing particles is ionized and thus forms charged dust particles, which are collected on a grounded surface energized β. Typical condensed air The filter is disclosed in U.S. Patent No. 2,593,869, issued to Fruth (1952), which first ionizes the air with particles, and then passes the air between parallel plates charged with opposite charges. On those plates. This type of condensing air filter is extremely efficient when the plates are initially clean. However, its effectiveness will decrease as the plates are covered with collected dust. Therefore, regular cleaning is required to maintain its effectiveness. Cleaning this type of condensing air filter is very cumbersome and expensive. It is also known to make disposable filter layers from carbon particles and fibers such as glass or wool to filter airborne particles. The filtering efficiency of these filtering layers can be enhanced by ionizing the air and dust particles before entering the filtering layer. U.S. Patent No. 3,706,182 to Sargent (1972) and U.S. Patent No. 4,244,710 to 20Burger (l981) both disclose this design. Β Both of the foregoing, the ions are introduced through an air stream The ion emitter in the zone is introduced into the air stream, and the emitter is spaced apart from the filter layer for removing ionized particles.

Explanation of the invention (Consumer cooperation with the shell worker of the Central Bureau of Standards of the Ministry of Economic Affairs.11 印 * '| This is also the release of ions into the air conveyor in an intake stream, which has obtained US Patent No. 5,518,531. Regardless Whether to use ionization, it is well known that the filtering efficiency of non-conductive materials such as glass can be enhanced by polarizing the filter layer with a potential field with a high electric field gradient. The conventional patent based on the principle of polarization Two examples are U.S. Patent Nos. 4,549,833 and 4,828,586, which are disclosed below. The first patent discloses a pair of drum-linking mesh layers on the outside that can be used to enclose a pair of glass weaves. A middle grid with an "r-shape *" made of a thick metal wire mesh with a diameter of about 0.5 mm is charged in between. The middle grid is charged to a level of about 7000 volts and the outer screen is grounded. Screen-to-screen The distance is about 2 to 5 mm in order to generate an electric field gradient. This electric field gradient will polarize non-conductive glass fabrics, making them very capable of collecting dust particles, and thus more effective than non-polarized filters. This combination produces not much 15. One of the advantages of this type of filter is that as long as the dust-laden fiber potential is renewed, the accumulated gray dust can be easily removed * In any case, polarized air scrubber The efficiency is not as good as the condensing ionized air filter. Combining the characteristics of the secondary system can get considerable benefits. US Patent No. 5,403,383 issued to Jaisinghani discloses ~ a kind of "ionization field electric efficiency filter", of which It is the dielectric material that allows the air to pass through the metal wire first, and then reach the downstream side. It has a grounded electrode. In order to enhance the polarization, Jaisinghani added a charged "control grid" upstream of the ionization wire of the air flow. Grid ", which provides energy production of 10 (please read the back., 511 this item, and then fill out this page" ir binding 20 -4- This paper size applies to Chinese national standard cars (CNS > A4 size (210x297 mm) ) Economy Printed by the Central Standards Bureau Shellfish Consumer Cooperative 4 3 4 0 5 0 A7 B7 V. Description of the invention () Various electric field gradients of the desired degree of ionization. Because the ionization metal wire is separated from the filter and permanently connected to the support body Therefore, the replacement of the filter will not hinder these ionized metal wires. "There is also a case in which the priority was disclosed in the application of NOZAKI, application number 5 85/02792 and published on July 4, 1985. The certification documents point out that the ion generating needle needs to be installed on a fixed grounded plate surface, which is used to support a stack of absolutely discardable filter layers. The dust house of Kedian was worn by electrostatic attraction. Passed the concrete layer and was dragged to the board surface. It is also possible that the relevant literature was published in the February 1975 Jiutian Journal 10 in Volume 17 of the IBM Journal of Science and Technology. The inventor has obtained U.S. Patent No. 5,573,577, which uses an improved grid in a polarizing filter made of conductive fiber filaments with many protruding thin ends. Ionization occurs when the polarization supplementary filter layer is over-polarized to improve filtration efficiency. The grid is sandwiched by two fiber mats and 15 external ground electrode screens. In the process of ionizing air, it is important to minimize the generation of ozone. In addition to being unpleasant, the odor can cause harm if it exceeds a certain level. Any system dominated by ionization should minimize ozone generation. 20 Ozone production is related to energy consumption, which is the supply of current at a voltage. Designing and manufacturing high-voltage power supplies to carry large amounts of current is both complex and expensive. This is of great benefit when the high voltage supply is operating at a low energy level. By avoiding the generation of corona discharge and ozone, it is advantageous to use a low-energy high-voltage supply. -5- -------- f pack-(Please read the f-side note ri before filling this page) ΪΤ- This paper size is applicable to China National Standards (CNS) Λ4 specifications {2 丨 0 × 297 Gong) Shellfish Consumer Cooperative, Central Bureau of Standards, Ministry of Economic Affairs. 454 Γ 434050 A7 B7 V.

As for the most general and specific form of the present invention, it will be explained and defined in the scope of each patent application. The basic feature of the present invention is that ions are introduced into an air stream to be filtered by providing an ion generating source positioned adjacent to a complementary filter layer through which an air stream will pass. The ion generating source is preferably installed in the filter layer. In all cases, the ion generation source is provided to emit ions toward the intake airflow into the airflow toward the 15th, so that a supplementary filter layer and the airflow in front of the ionization source can form a The purpose of the ionized air region * is to generate an ion cloud that will diffuse into the air stream in the air intake region. It is best to have no ionic interference barriers so that the air stream will reach the supplementary filter layer during the air flow. All the micro-20 particles carried will make it holy. By arranging the ion generation source adjacent to the supplementary filter layer and directing the ion direction of the ion generation source toward the intake airflow region, the airflow flows through this region to reach, thereby creating a filter module with enhanced efficiency. The efficiency of this module can be further improved by using a polarizable material as the supplementary filter layer and -6 · paper size applicable to China National Standard (CNS) Λ4 specification (210X297 mm) (please read and read f.

Description of the invention () Polarize it with a potential field. In a preferred variation, the present invention provides a thin ionizer that can be attached to the front end of a filter to ionize the air entering the filter, and is thin enough to allow the filter to be inserted into the air. In the long hole of the filtering device. The ionizer preferably includes one or more sharply charged electrodes for generating ions, each of which is exposed to a local gradient electric field in its ion emission range, which has sufficient strength to generate ions in the air, but Does not produce undesired amounts of ozone. The electrode, such as a needle or a conductive fiber with a tip, can be placed on a thin, insulating support, which can be attached to a filter, 10 or directly adhered to a non-conductive filter The surface of the layer. An ionization generating element is connected to a high-voltage power supply. The power supply may be part of a power supply of an electronic filter. A special phenomenon supports the operation of the present invention. After the ion is generated, whether it is a positive or negative ion, it will immediately jump out of its source under the action of its mutual repulsion. Immediately next to the generation source, an "ionic wind" can be actually detected. By using an appropriately shaped and arranged electrode, and a potential with sufficient strength, the electric field gradient of the ion emission region on the electrode can be made with sufficient strength. To generate a sufficient amount of ion. These ions form a dense ion cloud which has a strong tendency to diffuse. This diffusion tendency is strong enough to cause the ions to enter the intake air stream through a suitably positioned electrode, even if the incoming air stream must be overcome The flow rate of the ion cloud moves upstream, and it also diffuses laterally. This helps to charge most, if not all, air with particles before reaching the filter layer.

Description of the invention (), Most of the Administering ionizing air filter in the filter layer before arrival, to increase in velocity when the air, ion cloud can be seen in the air stream and the extended slow penetration. In any case, tests have shown that when an ion cloud is taught by a high-speed gas stream, more ions are produced. The increase in ion production is due to the removal of the “back pressure” when 5 ions are emitted from the ion generation source and condensed into an ion cloud. Therefore, the advancement of Liyun from the ion source hinders the increase in air velocity. For large filtration areas, most or long ion generation sources can be used to ensure that most of the air before it reaches the filter layer is ionized. A variety of ion generating source morphologies can be used in accordance with the present invention. An insulated 10 support, preferably with a dome shape, may be provided with a needle as an ion generating element or an ion generating source. The needle can be placed in a recess on the surface of the support, so that the filter with the support can be inserted into the long hole of an air handling system without interference * or the needle can also be installed elastically and upright. Let's get the same result. Similarly, a linear electrode with a tip can emit 15 electrons at the tip and can also replace a needle. * In another embodiment, the ion generating source can be a piece of string with most protruding fiber tips, wherein the string has conductivity Sex. The normal cotton rope is dipped in a graphite solution. The hairy end of the string acts as an ion emitter and generates the least amount of ozone. 20 In a polarizing filter, the insulating support provides insulation between the ion-generating element and its adjacent filter, the filter having a conductive screen or a conductive surface on its outer surface as an inducement.

Description of the invention (j If the fiber supplementary filter layer attached to the conductive layer is non-conductive and if a counter electrode is connected with The distance between the conductive ropes is large enough to prevent arcing, and the insulating tape can be omitted. If the supplementary filter layer is thin, the insulating tape can prevent electricity from being generated. The adjacent screen, which is a counter electrode It should have a considerable potential difference with the ion 5 emitting electrode to form the necessary electric field gradient on the ion emitter to emit ions. The screen is preferably grounded. The size of the insulating support is selected so that Provide a gap between the ion generating element and the opposite electrode to ensure that the potential gradient in the periphery of the ion generating element is large enough to generate ions but not large enough to generate a corona 10 or an arc * for this purpose Must be careful not to provide too much on the insulating support Electron collection surface. An excessively large non-conductive surface will accumulate charges to dilute or reduce the density of the electric field gradient around the ion generating element, thereby preventing the generation of ions. 15 Another embodiment has a counter electrode disposed on the impurity. The sub-emitter is located downstream on a filter pad, and the opposite electrode can be a frame assembly equipped with the filter layer, or a metal delivery pipe that transports air to the filter assembly.

This configuration improves the efficiency of the filter because the charged dust particles are more easily captured by the filter pad 40. Figures twelve and twelve A show another configuration of Figure Η—and Figure Α. In this case, the insulating tape 37 and the conductive rope 38 are placed at the front end of the fiber mat 40. Behind the fiber mat 40 is a screen 36A as a counter electrode. The insulating tape 37 reduces the risk of arcing between the high-charge conductive rope 38 and the ground screen 36A. In this configuration, an electrostatic field is generated between the conductive rope 38 and the screen 36A, which, in addition to forming ions, also polarizes the fiber pad 40 at least locally. In this case, the efficiency of the filter will increase due to the additional polarized filter pads. When the dust particles are charged by the ions 39 emitted through the ionizer 38, the polarized filter layer 40 particularly easily adsorbs the dust particles. Another similar arrangement is shown in Figures 13 and 13A. Here, the insulating edge band 37 is placed on the back of the filter pad 40 and in front of the screen / counter electrode 36A to prevent an electric arc from passing through the filter pad 40. This configuration provides a better polarized fiber mat 40 because the mat is in more direct contact with ionization to generate a conductive rope. In Figs. 14 and 14A, the supplementary filter layer 40 shown in Fig. 12 is replaced by a supplementary filter layer 40A having a conductivity of 20. The filter layer 40 may be composed of a conductive plastic filament or a non-conductive filament covered with a conductive layer such as carbon. Advantageously, a carbon coating can also absorb odors. The use of a conductive supplementary filter layer 40A is believed to reduce the charge accumulation between the supplementary filter layers 40A, and the accumulation of charge between the supplementary filter layers will reduce the emission. -16- (Please read the note on the back before filling in this Page)

Figures 15 and 15A reveal that an externally attached rope-type ion emitter 38 is mounted on a "sandwich" consisting of two screens 36, 36A containing a polarizing complementary filter layer 40. In this case, the charged dust particles 39 are expected to pass through the holes of the upper and lower screens 36 due to their inclusion in the air flow. Once they pass through the screen 36, the charged dust particles will be supplemented by the filter layer 40. The filter layer 40 can be polarized at will by providing different voltages for the upper screens 36, 36A. By providing an ionizer, which is thin and attached to the surface of a filter element 10, this A combination unit can be simply inserted into the long hole 31 of an air delivery pipe 30, as shown in FIG. When a filter 10 carries an attached high-pressure supplier 11, a combined unit is created which has a low price, is easy to install and maintain, and has extremely high efficiency in cleaning air or other fluids. 15 Alternatively, an ion emitter can be mounted on a filter 10 as shown in FIG. 16. An ionization generating element support 1 can be mounted on a thin arm 33 made of insulating material. An ion generating source 2 is positioned adjacent to the intake side of the filter 10, as shown in FIG. 16A. As long as a filter is convenient to install an ion generating source 2, it is enough for an ion generating source 2 to be installed adjacent to the filter by an independent 20. The test compares a filter without an ionizer and an identical filter. The ionizer is complete. The results are shown in the graph in Figure 17. The upper curve in Figure 17 represents the test results for a polarizer without external ionization. The results represent -17- in a closed space at different unit times (Please read the notes on the back before filling out this page) Ding-¾.

Description of the invention () Remove the smoke particles and measure with a particle size of 0.3 microns. The lower curve provides the test results for the same filter with four ionization generators on the outside of its intake surface. The rate of dust particle content reduction was significantly higher in those with external ionization. This result represents a major improvement in air cleaning efficiency. 5 The foregoing constitutes a description of certain embodiments, by which the invention is shown and applied.
