【考案の詳細な説明】 〔産業上の利用分野〕 本考案は、電気集塵器のコレクタ電極板に関するもの
である。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a collector electrode plate of an electrostatic precipitator.
電気集塵器には、第11図示のように気流中に含まれて
いる粉塵粒子を荷電するアイオナイザ１の下流側にアイ

レフィルタ３を設けたものがある。As shown in FIG. 11, the electric dust collector is provided with a collector 2 for collecting charged particles passing through the ionizer 1 downstream of an ionizer 1 for charging dust particles contained in an air flow. Is provided with a prefilter 3 such as a wire mesh.

コンパクトに製作することができる。In this electrostatic precipitator, the ground electrode plate 4 of the ionizer 1
If the dimension L in the airflow direction can be shortened, the current density increases even if the discharge current per unit length is the same, and the dust particles can be charged to a high charge amount in a short time. The electric dust collector can be manufactured to be thin and compact by an amount corresponding to the reduction of the dimension L.

１の寸法Ｌを短くするには、限界があった。However, when the dimension L is actually shortened, not only the discharge from the ionization line 5 of the ionizer 1 to the ground electrode plate 4 of the ionizer 1 but also the discharge to the ground electrode plate of the collector 2 causes a decrease in the particle charge rate. I do. Further, when dust particles are deposited on each ground electrode plate of the collector 2 by its collecting action, or when the electrode plate of the collector 2
As shown, a conductive paint 7 is applied to one surface of the insulating substrate 6 from the contact portion 7 to the center of the substrate 6, and a semi-insulating paint 9 is applied to the entire surface of the substrate 6 except for a portion where the spacer projection 8 is formed. When the electrode plate 10 has a specific resistance and has a certain value, a potential difference is generated by positive ions (negative ions in the case of negative application) flowing from the ionizer 1 and each ground electrode plate of the collector is formed. When the negative polarity corona occurs at the tip of the electrode plate, the opposite polarity ions flow into the ionizer 1, and when there are minute irregularities 11 on the upstream edge of the electrode plate 10, the reverse polarity corona Occurs, and the opposite polarity ions generated by the opposite polarity corona flow into the ionizer. Since the electric force pulling the ionization line 5 is weakened by these opposite polarity ions, the ionization line 5 returns to its original position by its own tension. Then, the generation of the opposite polarity ions stops, and the ionization wire 5 is pulled again by the electric force. The tension of the ionization line 5 by the electric force and the return by the tension of the ionization line 5 itself are alternately repeated, and
The ionizing wire 5 oscillates in the airflow direction, and as a result, a spark is generated between the ionizing wire 5 and the collector electrode plate, or the ionizing wire 5
However, there is a limit in shortening the dimension L of the ionizer 1 due to a drawback such as disconnection.

た。Also, when dust particles accumulate on the collector electrode plate while the electric precipitator is operating and the dust collection efficiency decreases, each collector electrode plate is taken out of the collector frame, immersed in a cleaning solution for a certain time, and then washed with water. Work to dry and then return to the collector frame,
The amount of dust particles deposited depends on the collector electrode plate as shown in Fig. 13.
32, the amount is large at the upstream edge and decreases as it reaches the downstream edge.If dust particles accumulate on an insulating sheet such as plastic, it can be easily washed from the sheet surface during cleaning. Although it can be dropped, if it accumulates on the coating surface of the paint, it adheres strongly to the coating surface and cannot be easily washed off. In the case where the insulating paint 34 is applied, if the cleaning time is short, dust particles on the upstream edge of the collector electrode plate 32 are not cleaned, and the upstream edge of the collector electrode plate 32 is not cleaned. If it is attempted to wash all the accumulated dust particles, there is a problem that the time required for cleaning is long and the cleaning efficiency is reduced accordingly.

を目的とするものである。The present invention shortens the size of the ionizer and the collector electrode plate in the airflow direction, and concentrates the discharge from the ionization wire on the ground electrode plate of the ionizer opposite to the ionization wire without going to the collector. It is possible to charge a large amount of charge, prevent reverse ionization from the collector to the ionizer, and assemble a thin and compact electric dust collector as a whole without widening the gap between the ionizer and the collector. It is another object of the present invention to provide a collector electrode plate which can easily clean deposited dust particles and can prevent occurrence of a short circuit between the collector electrode plates.

る。Since the present invention is configured as described above, the lines of electric force from each ionization line of the ionizer do not go to the collector, but concentrate on the ground electrode plate of the ionizer facing each ionization line, that is, the discharge current is reduced. Owing to the concentrated flow on the ground electrode plate, the dust particles can be charged with a high amount of charge, the charging efficiency of the dust particles increases, the collection efficiency can be increased, and the reverse ionization from the collector to the ionizer can be performed. In order to obtain the same collection efficiency, the current per unit length can be reduced, and the input power can be reduced even in consideration of the increase in the applied voltage. . In addition, the amount of ozone generation can be reduced by reducing the current. Moreover,
It is possible to shorten the size of the ionizer in the airflow direction, and the collector assembled by shortening the size of the collector electrode plate of the present invention in the airflow direction can be located downstream of the ionizer. The dust collector can be made thin and compact as a whole. Also, by exposing the edge of an insulating sheet made of plastic or the like at the upstream edge of the collector electrode plate where a large amount of dust particles easily accumulate, cleaning of the collector electrode plate on which dust particles are deposited is simplified, and cleaning is performed. And the cleaning efficiency can be increased. In addition, by providing an insulating part at either the upstream edge or the downstream edge of one or both of the high-voltage electrode plate and the ground electrode plate of the collector, the occurrence of a short circuit between the electrode plates of the collector is prevented. It has such advantages as possible.

集塵器のコレクタ。1. A plurality of high-voltage electrode plates and a plurality of ground electrode plates are provided alternately and in parallel with an airflow downstream of an ionizer whose dimension in the airflow direction is shortened. In a two-stage electrostatic precipitator in which the dimension in the airflow direction is shortened, and a collector formed by forming a conductive layer at a portion along the center line of the plate surface on one side of the insulating substrate is brought closer,
Each high-voltage electrode plate has a specific resistance by forming a semiconductive layer on the same plate surface as the conductive layer, and each ground electrode plate has a semiconductive layer on the same plate surface as the conductive layer. The collector of the electrostatic precipitator is characterized in that the collector has a specific resistance value, and a reverse ionization preventing insulating portion is provided at the upstream edge.
