摘要： PROBLEM TO BE SOLVED: To provide an electrostatic precipitator which has a simpler structure of a high voltage generator to apply high voltage to each electrode of an electrostatic charge part and a dust collecting part of the electrostatic precipitator and which is capable of effectively controlling the re-scattering while maintaining high dust collecting capability.
SOLUTION: The high voltage generating means to generate high voltage of positive/negative dissymmetry having one-sided proportion of the negative or positive side is used as an application means of high voltage to the electrode of the dust collecting part of the electrostatic precipitator. As the positive/negative dissymmetry high voltage, it is preferable to use unsymmetrical square wave high voltage of which the output voltage value and output time of straight polarity and negative polarity are different and high voltage of straight polarity or negative polarity of which the output voltage is reduced to 0 V periodically and instantly and is restored again.

摘要： PROBLEM TO BE SOLVED: To provide an electric dust collector which can comprehensively realize the washing structure of an electrode plate causing no remnant of dust by washing, decrease in the pressure drop in the passage of dust-containing air, reduction of the cost, or the like. SOLUTION: This electric dust collector 1 differs from a conventional one in that only a water washing unit 4 disposed above each dust collecting unit 3 is used as the water washing unit which supplies washing water to wash out the dust depositing in the dust collecting unit 3. The water washing unit 4 is equipped with: a pipe 41 for five nozzles to which a plurality of water nozzles 5 to inject high-pressure washing water 8 downward are attached; and a header pipe 43 which supplies the washing water 8 in common to the pipe 41 for five nozzles.

摘要： PROBLEM TO BE SOLVED: To provide a compact electric dust collector capable of preventing scattered particles contained in treated air being discharged therefrom from depositing and sticking onto a wall face or the like of a downstream facility without decreasing its dust collection efficiency.
SOLUTION: The electric dust collector having a two stage structure is comprised of a charging section for charging particles floating in air by ionizing the air being supplied by means of corona discharge and a dust collection section for collecting the particles floating in the air charged in the above charging section using an electrode that forms a high electric field and adsorbs the particles. The above charging section is comprised of a cathode discharge part for performing cathodic discharge and an anode discharge part for performing anodic discharge each separately disposed therein. Each of the cathodically charged air and the anodically charged air charged in the cathode discharge part and the anode discharge part of the charging section respectively is separately sent to the dust collection section to be mixed with each other in the rear part thereof, whereby the charge of the cathodically charged particles and the charge of the anodically charged particles are bonded and neutralized.

摘要： PROBLEM TO BE SOLVED: To provide an electrostatic precipitator which saves electric power and can obtain high dust collection performance. SOLUTION: When a high negative dc voltage is applied from a power source 6 to the electric discharge electrodes 2 of a charged part 1, a corona discharge of negative polarity is generated between grounded electrodes 5 facing in parallel. Since the lengths of projections 3 and 4 to be the origins of the corona discharge are different from each other, the corona discharge regions are hierarchical. In the vicinity of the boundary between two discharge regions 7 generated from the longer projection 3 of the adjacent lengths, a discharge region 8 is generated from the shorter projection 4. With regard to the air flow direction, a part small in electric current density is decreased. By making the corona discharge regions hierarchical, the corona discharge regions as a whole can be generated efficiently. COPYRIGHT: (C)2004,JPO&NCIPI
