摘要： PROBLEM TO BE SOLVED: To clean the air containing dust in tunnel by preventing the dust form being rescattered. SOLUTION: When dust-containing air is introduced into a silent discharge type electric dust collector, particles 15 are charged in two poles of positive and negative at a silent discharge space between parallel plane plate electrodes and captured on the electrodes. When the polarity of an attracted electrode is positive, negatively charged particles are captured on the electrode. The negative charge of the particles is kept since a dielectric body 13 is allowed to exist between a metal electrode 12 and the charged particles. When the polarity of applied voltage is reversed and the polarity of an attracted electrode becomes negative, positively charged particle are captured on the electrode. The captured positively charged particles and the negatively charged particle on the electrodes are neutralized, and more electrostatic aggregation is not caused. That is, the aggregation between the particles on the electrode is suppressed. As a result, the particles are uniformly deposited on the surface of the electrode and rescattering is remarkably suppressed since the fluid resistance force of the deposited particles is low.

摘要： PROBLEM TO BE SOLVED: To remove dust particles and harmful gas at the same time with high efficiency. SOLUTION: A charge part 1 is constituted of a dielectric 4 comprising a photocatalytic substance or an electrode having a photocatalytic film to perform silent discharge and the energy of the light or active seed generated by silent discharge is accumulated on the surface of the photocatalytic electrode to be converted to the electrode surface energy of the dielectric 4 and this converted energy is allowed to contribute to the removal of harmful gas such as NOx or the like.

摘要： PROBLEM TO BE SOLVED: To restrain the effect of floating particles, harmful gas, and leak ions in air on dust by giving electric charges to particles floating in the air in a charged part and generating plasma columns in which particles of both minus ions and plus ions are present at the same time in the charged part. SOLUTION: By applying a AC high voltage power source 13 to particles floating in the air in a silent electrical discharge type charged part 10, a lot of plasma columns 30 in which minus ions and plus ions are present at the same time are made in a state in which they are repeatedly generated and dissipated in parallel. In this state, into a space of the charged part in which the plasma columns 30 are present, air containing smoke dust particles 40 is made to flow. The smoke dust particles 40 slip out of the space of the charged part 10 in a state of positively or negatively charged particles 50 while they pass through the plasma columns 30. In this way, not only the floating particles 40 but also harmful gas containing gas components can be removed.

摘要： PROBLEM TO BE SOLVED: To efficiently collect dust from air containing the dust by preventing it from scattering again. SOLUTION: A rectangular wave high voltage is applied between dust collecting electrodes. In the section of a positive voltage, negatively charged floating particles are collected on the dust collecting electrode of positive polarity to which the high voltage is applied as indicated in (a). The collected particles are immediately positively charged and form beaded plate agglomerates. In the following section of changing from positive to negative, the polarity of the voltage applied to the dust collecting electrodes is suddenly changed from positive to negative, the beaded plate agglomerates (positively charged) receive force in the direction of the dust collecting electrode of negative polarity by static electricity and change to spherical agglomerates as indicated in (b). In the following section of a negative voltage, as indicated in (c), though the collected particles are negatively charged on the dust collecting electrode of the negative polarity, they change to the spherical agglomerates, wind force and electrostatic force acting as peeling force are reduced and they do not scatter again.

摘要： PROBLEM TO BE SOLVED: To provide a silent discharge type air cleaning device constituted so as to achieve high dust collecting efficiency. SOLUTION: When the silent discharge type air cleaning device is constituted, an undulate shape part (not shown) for forming an edge part (corner or top part) or a recessed shape part (in the Figure, many circular through-holes) is provided on the surface of the back electrode 4. As a result, a higher dust collecting efficiency is achieved since many silent discharge columns having large energy are generated starting point from the edge part.

摘要： PROBLEM TO BE SOLVED: To suppress the concn. of discharged NO2 to a definite value or less and to enable power saving operation. SOLUTION: An air cleaner 13 includes a silent discharge type charge part 13a, a dust collecting part 13b, an ozone killer part 13c, an NO2 concn. measuring device 13d and a power supply frequency control part 13e to which an NO2 concn. detection signal is inputted. A discharge current value optimum to an NO2 removing ratio is 0.4 mA and, if the discharge current value is 0.4 mA or more, the NO2 removing ratio per injected energy lowers and the concn. of residual O3 increases. Therefore, by measuring the concn. of NO2 on the downstream side of this air cleaner and adjusting power supply frequency, a discharge current is controlled and injection power can be optimized.

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： PROBLEM TO BE SOLVED: To supply pure water without using a pump by making the level of the pure water flowing in a gas non-return device lower than the level of a water electrolyzer in contact with an anode. SOLUTION: A gas non-return device 24 is fixed to a pipe 27 for supplying pure water to a water electrolyzer 25. Oxygen and the pure water stored in a pure water tank 23 are supplied to the anode of the electrolyzer 25 by the pipe 27. Further, a level difference H is formed between the level of pure water flowing through the gas non-return device 24 and that of the pure water in contact with the anode. The oxygen generated from the anode is introduced into the tank 23 by buoyancy. In this case, when the level difference H is >=150mm, any oxygen is not accumulated in the non-return device 24, the passage of pure water is not blocked by the gas-phase oxygen, and the pure water is sent to the electrolyzer 25 without using a pump.
