Definitions
- the present invention relates to a discharge device that performs streamer discharge by applying a periodically varying voltage, and an air purifier equipped with the discharge device.
- an air purifier equipped with a discharge device has been used as means for decomposing and removing odorous components and harmful components by plasma generated by discharge.
- streamer discharge type air purifiers that generate low-temperature plasma by streamer discharge can achieve high air purification efficiency with relatively low power, so that they can decompose harmful substances and deodorize them. This technique is suitable for performing the above.
- This streamer discharge type air purifier includes, as a discharge device, a plurality of discharge electrodes, a counter electrode facing the discharge electrodes, and power supply means for applying a voltage to both electrodes. .
- a voltage is applied to both electrodes from the power supply means, streamer discharge is performed between both electrodes, and low temperature plasma is generated.
- the active species high-speed electrons, ions, radicals, other excited molecules, etc. generated by the generation of this low-temperature plasma are brought into contact with harmful components and odorous components in the air to be treated, so that these components Decomposition is removed (see Patent Document 1).
- streamer discharge type discharge device has high decomposition efficiency with respect to odor components and harmful components, but the streamer discharge state (streamer discharge occurrence frequency and occurrence state) has various influencing factors. It has the characteristic that it is easily affected by sensitivity. For this reason, if the discharge characteristics of each electrode vary due to, for example, dimensional errors during assembly of the discharge electrodes, assembly errors, or the adhesion of dust between the electrodes, the stream discharge becomes stable. There was a problem that it was not done.
- FIG. Figure 10 shows the discharge characteristics of each of the electrodes (a, b, c).
- the horizontal axis represents the applied voltage (V) applied to these electrodes, and the vertical axis represents the discharge current flowing during discharge. (I).
- these electrodes (a B, c) have variations in discharge characteristics for the reasons described above. Under such conditions, when a predetermined applied voltage (for example, VI in FIG. 10) is applied to each electrode, a voltage necessary for discharge is applied to some electrodes (for example, the electrode c in FIG. 10). There was a possibility that the streamer discharge could not be performed. If streamer discharge is not performed on some electrodes in this way, the amount of active species such as fast electrons and radicals is reduced, and the efficiency of air purification equipment equipped with this discharge device is reduced. There was a problem of doing so.

- a micro arc called a leader (53) is generated from the discharge electrode (41) toward the counter electrode (42).
- air is ionized into electrons (51) and charged particles (52) by a strong potential gradient.
- the charged particles (52) reach the counter electrode (42) side, one discharge is completed.
- Fig. 6 is a graph showing the generation characteristics of streamer discharge in a discharge device to which a periodically varying voltage (Vp) is applied.
- the horizontal axis represents time (t), and the vertical axis Is the applied voltage (V).
- the discharge electrode has a characteristic of performing streamer discharge when a voltage of, for example, (Vmin) or higher is applied.
- next streamer discharge is not performed at time t2, and the next streamer discharge is performed at time t3 when the voltage (Vp) reaches or exceeds (Vmin) for the first time after the discharge period (Ts) has elapsed. Therefore, the time from t2 to t3 (the period indicated by the broken line arrow in FIG. 6) becomes the discharge delay time, leading to a discharge loss in both electrodes (41, 42). As described above, in order to perform the streamer discharge stably and to exhibit the high air purification efficiency, it is desired to suppress the discharge loss due to the discharge delay time as much as possible.
- the present invention has been made in view of the points to be worked on, and an object of the present invention is to reduce a discharge loss between both electrodes in a discharge device to which a periodically varying voltage is applied. It is to enable stable streamer discharge. Means for solving the problem
- the discharge loss of the discharge device can be reduced by increasing the frequency of the voltage applied to the discharge electrode and the counter electrode.
- the first invention comprises a plurality of discharge electrodes (41) and a counter electrode (42) facing the discharge electrodes (41), and has a period from the power supply means (45). It is assumed that the discharge device performs a streamer discharge between both electrodes (41, 42) by applying a voltage that fluctuates to both electrodes (41, 42). In this discharge device, the frequency (IV) of the voltage applied to both electrodes (41, 42) and the frequency (fs) of the streamer discharge generated in a pulse form between both electrodes (41, 42) are obtained. ,
- the “streamer discharge frequency (fs)” is the frequency of the streamer discharge generated in the form of pulses due to the residual charged particles (52) shown in FIG. 6, and the reciprocal of the discharge cycle (Ts) described above.
- the frequency (IV) of the periodically fluctuating voltage becomes equal to or higher than the streamer discharge frequency (fs), and the power supply means (45) to both electrodes (41, 42). Applied.
- the period (Tv) (voltage period) of the periodically changing voltage is equal to or less than the discharge period (Ts).

- a voltage of frequency (IV) is applied from the power supply means (45) to both electrodes (41, 42).
- the streamer discharge is generated in pulses due to the remaining charged particles (52). For this reason, if the distance until the charged particle (52) reaches the counter electrode (42), that is, the gap length (G), becomes shorter, the charged particle (52) remains. The time is also shortened and the discharge frequency (fs) is increased. On the other hand, if the gap length (G) becomes longer, the remaining time of the charged particles (52) also becomes longer, and the discharge frequency (gas becomes smaller. Thus, the discharge frequency (fs) of the streamer discharge is the gap length. The discharge frequency (fs) can be roughly estimated from this gap length (G).

Applied to For this reason, the width of the fluctuation of the voltage applied to both electrodes (41, 42) is within 10% of the average voltage (Va).
- the streamer discharge has a feature that a spark is easily generated as compared with a discharge such as electrostatic dust collection. For this reason, when the amplitude (Vp-p) is larger than the average voltage (Va) of the applied voltage, the voltage applied to both electrodes (41, 42) increases, and this voltage reaches the spark region. Otherwise, sparks may occur between the electrodes (41, 42). is there.
- the range of fluctuation of the voltage applied to both electrodes (41, 42) is narrowed to 10% or less with respect to the average voltage (Va).
- the applied voltage can be prevented from reaching the spark region, and the occurrence of this spark can be suppressed.
- the fifth invention includes a discharge device that performs streamer discharge between the discharge electrode (41) and the counter electrode (42), and the air to be treated is circulated between the electrodes (41, 42).

For this reason, the voltage frequency (IV) can be reliably set to the discharge frequency (fs) or more, and the discharge delay time during the streamer discharge can be shortened. Therefore, the discharge loss in this discharge device can be reliably suppressed.
- a voltage having a voltage frequency (IV) of not less than the discharge frequency (fs) and not less than 20 [kHz] is applied.
- the voltage frequency (IV) can be made higher than the discharge frequency of general stream discharge (less than about 20 [kHz]), and the discharge delay time during streamer discharge can be shortened.
- the voltage frequency (IV) is set to 20 [kHz] or higher, the frequency of the sound accompanying the output of this voltage is increased from the human audible range. Accordingly, noise generated near the power supply means (45) can be suppressed.

For this reason, the range of the voltage applied to both electrodes (41, 42) is narrowed, and the voltage applied to both electrodes (41, 42) can be prevented from reaching the spark region. Therefore, the occurrence of sparks can be suppressed, and the stability of the streamer discharge in this discharge device can be improved.
