摘要： PURPOSE:To improve performance by arranging a pair of electrodes via a space to constitute dust collecting electrodes, coating the one electrode with an inorg. compd. and applying a high voltage to this electrode. CONSTITUTION:The dust collecting electrodes 3 are constituted in the same manner as for a conventional two-stage type electrostatic dust collector. Namely corona 15 generated by the discharge electrode 32 of a DC high-voltage power source 31 to electrify the dust in the first stage. The dust is collected on the dust collecting electrode 34 by the Coulomb force generated by the electric field consisting of a high-voltage electrode plate 33 of the same polarity as the polarity of the discharge electrode 32 and the grounded dust collecting electrode 34 in the second stage. This highvoltage electrode plate 33 is coated with the inorg. compd. such as hydrous alumino silicate ore. In such a case, the electrode plate is formed by coating the surface of a planar electrically conductive material, for example, metal, such as aluminum, with the powder of the hydrous alumino silicate ore and press forming the material.

摘要： PURPOSE:To obtain an electrostatic precipitator having high dust collecting efficiency by providing shield plates which have electrically insulating property and dielectric property and disturb the flow of air at an inlet of a dust collecting part, inside the dust collecting part, etc. CONSTITUTION:In an electrostatic precipitator in which a dust collecting electrode is constituted of at least a set of electrodes, that is, a charging electrode 21, dust collecting high voltage electrodes 22, a 1st earth electrode 31 and a 2nd earth electrode 32 which are insulated from each other and potential difference is applied between the electrodes to collect dust 200 in air charged in the electric field of a corona, shield plates 52, 53 which have insulating property and dielectric property are installed in an inlet of the dust collecting part and/or the dust collecting electrode part to disturb the flow of air in the dust collecting electrode part. As a result, since air introduced into the dust collecting part generates turbulence in the flow and moves toward the electrode surface, dust collection is easily affected by the coulomb force to increase the dust collecting efficiency.

摘要： PURPOSE:To obtain an air purifier which has high dust collecting rate and is miniaturized by providing a charging part on the upstream side of gas flow, providing a pleat electrode so as to make it intersect perpendicularly to the gas flow on the downstream side, inserting collecting electrode from the upstream and downstream sides and applying high voltage so that the collecting electrodes may be opposite in porarity to the charging polarity given to particles by the charging part on the upstream side of the gas flow. CONSTITUTION:A charging part 6 is provided on the upstream side of gas flow, and a pleat electrode 11 is provided so as to be crossed perpendicularly with the gas flow on the downstream side. Collecting electrodes 9a, 9b are inserted from at least one of the upstream and downstream sides. High voltage is applied between the collecting electrodes 9a, 9b and the pleat electrode 11 so that the collecting electrodes 9a, 9b may be opposite in polarity to the charging polarity given to particles by the charging part on the upstream side of the gas flow. In this way, in the collecting electrode 9a on the upstream side, by electrostatic force and the slowing down of gas flow rate near the electrode 9a, high dust collecting efficiency is obtained, and in the electrode 9b, by electrostatic force and the refraction action of the gas flow, high dust collecting efficiency is obtained.

摘要： PURPOSE:To attain stable dust collecting efficiency for a long time by preventing a lowering of life of discharge electrodes due to abnormal discharge of an electric precipitator, simultaneously reducing the damage on electrodes caused by spattering action of electrified dust particles and preventing the corrosion and erosion of electrodes at the time of operation or electrode washing. CONSTITUTION:Discharge electrodes 8 and counter electrodes 9 are installed in an electrifying art 10 for electrifying dust particles in the air by corona discharge. Among the electrodes, at least the surface of the electrode having baser potential than the other electrode and on the electron discharging side is composed of at least one material selected from tungsten (W), titanium carbide (TiC), zirconium carbide (ZrC) and tantalum boride (LaB) to improve electron electric field discharging performance and corrosion resistivity of the electrodes 8.

摘要： PURPOSE:To stably capture dust particles without entailing a cost increase. CONSTITUTION:A filter 1 of the electrostatic precipitation type air cleaner is formed by having a conductor sheet 14, exposing this conductor sheet 14 and providing terminals 16 on the end face. A good conductive part 14a enhanced in electrical conductivity is provided in the contact part of the terminals 16 formed of a part of the conductor sheet 14 with contact terminals 27. The electrical conductivity between the contact terminals 27 and the terminals 16 is enhanced by this good conductive part 14a and the need for enhancing the electrical conductivity over the entire part of the conductor sheet 14 is eliminated.

摘要： PURPOSE:To hold the respective open-cell foamed bodies at uniform electric charge and to form an electric charge flow between the open-cell foamed bodies by constituting a collection means of a plurality of open-cell foamed bodies stuck with activated carbon having electrical conductivity and electrically connecting this collection means with an electric charge storage part and holding the each open-cell foamed body at uniform electric potential. CONSTITUTION:A fluid cleaner is constituted so that air is passed through an ionizer 22 to charge particles and the air contg. these charged particles must be passed through an open-cell foamed structure made of the charged activated carbon sheets 24, 25. These charged particles mutually act on an electric field formed by the charged sheets and are collected on the sheets 24, 25. Effect of the activated carbon sheets 24, 25 utilized as an absorptive material is deteriorated by contamination of dust particles. However, since at least two sheets of activated carbon sheet are utilized, both the effective region brought into contact between activated carbon and the gas to be attracted, and the elapsed time are regulated at least to two times. Therefore contamination coefficient can be compensated. Thereby the particles are collected by impact, shut-off and electric force. Furthermore, ozone and bromine can be removed by attraction.
