用でミストなどを捕集している。[Prior Art] Conventionally, inertial collection using a wet electrostatic precipitator or a mist eliminator has been the main method for simultaneously collecting mist and dust in exhaust gas. In the case of a wet electrostatic precipitator, the collection efficiency is high and it can also collect fine mist such as S (h mist), but due to the high equipment cost, it is not used at the exit of the evacuation device, etc. Usually, as shown in Figures 9 and 10, a mesh or filler made of synthetic resin or metal is placed perpendicular to the gas flow, or a large number of bent plate-like meshes or fillers are placed orthogonally to the gas flow. By arranging the plates parallel to the gas flow, mist etc. are collected using inertial collection action.
従来のミストエリミネータには次のような課題があった
。Conventional mist eliminators had the following problems.
１、） ＋Ｍ性力を利用しているため、微細なミスト
及びダス１〜に対しては集しん効率が低い。特に１ミク
ロン以下のサブミクロン領域では著しく効率が低下する
。1.) Since the +M force is utilized, the collection efficiency is low for fine mist and dust 1~. Particularly in the submicron region of 1 micron or less, the efficiency decreases significantly.
２） また捕集効率を−１−げるためには充填物の密度
を上げる等の方法が考えられるが、その場合著しく圧力
損失が増大する等の問題がある。2) In order to increase the collection efficiency by 1-1, it is possible to consider methods such as increasing the density of the packing, but in this case there are problems such as a significant increase in pressure loss.
３） 微細なミスト等を捕集する手段としては電気力が
有効であり、湿式電気集じん器などが有効であるが、一
般にコストが高くなる。3) Electric power is effective as a means to collect fine mist, etc., and wet electrostatic precipitators are effective, but they are generally expensive.
本発明は」−記課題を解決するため次の手段を講する。 The present invention takes the following measures to solve the problems mentioned above.
すなわち、ミストエリミネータとして、１） 流れに交

加する前圧電源とを設りる。That is, as a mist eliminator, 1) a first electrode that is provided across the flow and has a plurality of holes; and a non-conductive mensch-shaped electrode that is provided in parallel with the first electrode near the wake of the first electrode; and a filling layer on the upstream side of the first electrode,
a second electrode provided opposite to the first electrode; a third electrode provided opposite to the first electrode on the downstream side of the filling layer; a third electrode provided opposite to the first electrode; A pre-voltage power supply is provided for applying a high voltage between the second electrodes and between the first and third electrodes.
２） 上記第１項記載のミストエリミネータにおいて、
第］電極、充填物層および第２電極の組を複数組流れに
沿って設しＪる。2) In the mist eliminator described in item 1 above,
A plurality of sets of the first electrode, the filling layer, and the second electrode are provided along the flow.
１） 上記第１項に係る手段により、高圧電源から高圧
が印加された第２電極から第１電極へ向けてコロナ放電

荷を帯びる。1) By the means according to item 1 above, corona discharge is generated from the second electrode to which high voltage is applied from the high voltage power source toward the first electrode. Therefore, the dust and dust in the gas flow become charged.
電荷を帯びたミストやダス１〜は、−・部は第１電極に
電気集じんの原理で捕集されるか、その大部分はその孔

として捕集される。The - part of the charged mist and dust is collected by the first electrode using the principle of electrostatic precipitation, or most of it passes through the pores and enters the next filling layer. Sent. Within this packed layer, the relatively large grain size I. is mainly collected as inertial dust.

で分極され、コロナ放電により受けた電荷と同極の電荷
のみならず、反対の電荷もその表面に表れる。On the other hand, non-conductive filling and conductive mist coexist in the same filling layer, but since the filling is composed of mesoche-like material with a relatively large porosity, the mist is completely absorbed. There is almost no possibility that the filling layer surfaces on the side of the first electrode and the third electrode will be electrically short-circuited. Therefore, by applying high temperature pressure to the third electrode, a complex electric field is formed within the filling layer. In particular, the mist with large particle size collected on the surface of the filling generally has a large dielectric constant, so it is polarized in the electric field and carries not only charges of the same polarity as those received by corona discharge but also charges of the opposite polarity. It appears on its surface.

な力により効果的に捕集される。On the other hand, fine mist [...] and dust are charged by corona discharge, but as they pass through the filling layer, an electric force is generated between them and the surface of the polarized large-sized mist. That is, it is attracted to and collected by the oppositely charged surface due to Coulomb force. In this case, since the distance between large-sized mist and fine mist is close, they are effectively collected by electric force.
このようにして、ガス中のミスＩ・やダストが容易に捕
集されるようになる。In this way, dust and dust in the gas can be easily collected.

さらに向上する。2) Since multiple sets of silk for the first electrode, filling layer, and third electrode are used by the means according to item 2, mist and dust in the gas can be collected by the same action as in item 1. The rate will further improve.

内には複雑な電界が形成される。On the other hand, in the same filling layer 3, non-conductive fillings and conductive mistakes 1~ are mixed, but since the filling is composed of a non-shrink material with a relatively large porosity, the mist are completely connected to form the filling layer 3 of the first electrode 2 and the five third electrodes.
There is little chance of electrically shorting the surfaces. Therefore, by applying a high voltage to the third electrode 5, the filling layer 3
A complex electric field is formed inside.

電荷のみならず、反対の電荷もその表面に表れる。As shown in FIG. 5, the large particle size I-f collected in the filler 15 itself generally has a large dielectric constant, so it is polarized in the electric field and has the same polarity as the charge received by the corona discharge. Not only the charge of , but also the opposite charge appears on its surface.

It is attracted to the opposite charged surface by the Coucon force and is collected. In this case,
Because the distance between large-sized mist and fine mist is close, they are effectively collected by electric force. Further, although not shown, the polarization of the filler 15 itself is shifted, so that fine particles such as I and dust are directly collected on the filler 15 by electric force.

ストやミストが除去されるようになる。The step of removing the charge layer 3 near the third electrode 5 has the same effect as described above. Furthermore, the two-liquid filling layer 3 receives a high-voltage electric field from the non-protruding side surface of the opposing second electrode 1.
It has the same effect as the downstream one. Therefore, it acts as if two stages of substantially equivalent parts were provided, and dust and mist can be removed with a high collection rate.
