摘要： PROBLEM TO BE SOLVED: To safely perform exchanging work, cleaning work and maintenance and inspecting work for a dust collecting unit. SOLUTION: A disclosed electric dust collecting unit comprises a corona discharge part 8 which generates corona discharge to make floating fine particles in air such as smoke particles of tabacco and toner to be charged with electricity, an electrically collecting part 9 arranged on the lee side of the corona discharge part 8 and for electrically collecting the suspended fine particles charged by means of the corona discharge part 8 and a box-type frame 10 both front and back faces of which are opened and the corona discharge part 8 are provided with a plurality of needle electrodes 8a whose sharp needle points are respectively arranged toward the lee side (to turn the back on the front face opening part of the box type frame 10).

摘要： PROBLEM TO BE SOLVED: To lower a space-charge electric field on a surrounding wall face, etc., and to prevent the contamination of a tunnel wall face by providing a charge neutralizer forming a plasma discharge column, in which negative ions and positive ions are present at the same time, in succession to the dust collecting part of an electrostatic precipitator. SOLUTION: The suspended particles introduced from the inflow side A of an electrostatic precipitator 50 are charged in a charging part 1, about 80% of the particles are collected by the collecting part 2, and the remaining 20% of the particles are discharged from the outflow side B of the dust collecting part 2. In this case, the remaining 20% of the particles are inputted to a charge neutralizer 100 consisting of a silent-discharge charging part and forming the positive and negative charges between the parallel electrode plates. The charges are neutralized by the plasma-discharge column by the silent discharge, and a space-charge electric field formed by itself is reduced to zero. Consequently, the driving force toward a wall is weakened, and the deposition of dust on the tunnel wall face, duct and further the main tunnel wall is reduced.

摘要： PURPOSE: To provide a treating method of a washing waste water of a dry electrostatic precipitator dispensing with a waste water treating device purifying and treating the washing waste water washing an inside of the dry electrostatic precipitator. CONSTITUTION: The washing waste water washing the inside of the dry electrostatic precipitator 10 is stored in a storage tank 26. The stored washing waste water is sprayed in an inlet side flue 12 of the operating dry electrostatic precipitator 10, and a water content of the sprayed washing waste water is atomized with a gas heat of a combustion waste gas 16 introduced in the dry electrostatic precipitator 10 through the inlet side flue 12 and also a solid content in the washing waste water is captured by the dry electrostatic precipitator 10.

摘要： PURPOSE:To provide a stage device provided with an attraction device having sufficiently large attracting force. CONSTITUTION:A stage device is provided with a lower plate 15, an upper plate 17 placed on the lower plate 15 so that it can be freely moved horizontally with respect to the lower plate 15, and a dust collecting means arranged on the upper plate 17 to collect dust generated when the upper plate is moved. Further, the dust collecting means is provided with an attraction member 19 for attracting dust, and an electrically charging means for charging either the attraction member 19 or dust with a positive charge, while charging the other of them with a negative charge for the purpose of attraction.

摘要： PURPOSE: To make it possible to achieve or correct a two-stage electrostatic filter which is cooperative with a U-shaped anode facing a baffle and is made from a minimum number of easy-to-assemble parts by providing the modular expansion of the filter with another cathodes by an extremely simple method for special requirements for discrete applications. CONSTITUTION: An ionization chamber and a precipitation chamber are composed of at least one inverted U-shaped cathode 10. The opposite ends of the cathode 10 are mechanically and electrically integrated with a transverse supporting section 20 and within which is provided with at least one baffle 10b extending parallel to outer arms 10a of the U-shaped cathode in the overall length of the part, but with a height lower than that of the arm 10a. The cathode 10 cooperates with U-shaped anodes 30 counterposed the baffle 10b and rendered mechanically integral by insulated supports 40. There are also provided another cathodes 110b for the modular expansion of the filter in the direction of its width. All of the constituted elements for making up the filter may be produced by extrusion molding on account of their special forms.
