Hereinafter, one embodiment of the present invention will be described based on the drawings. The dust collector collects dust 1 as shown in Figure 1.
3 is sucked and collected by a dust collector 1 through a hood 12 and a duct hose 10.
To explain in more detail, when the motor 4 rotates the fan 3, the dust 13 along with the air flows into the hood 12.
is sucked from. And the sucked dust 13
When passing through the charging device 14 , a high voltage is applied to the particles, the particles are charged, and the particles are sucked into the dust collector 1 . Thereafter, the air is filtered by the filter 2, and only clean air is discharged from the discharge port 5 to the outside. Filter 2
The collected dust 13 is applied with an external force (vibration) by the filter vibration lever 6 or falls due to its own weight and is received in the dust box 7. Once a certain amount of dust has been collected, the dust box is taken out and disposed of outside.

As shown in Figures 2 and 3, the input line 1
An output line 19 is drawn out from a high voltage generator 17 that converts a voltage of 8 (usually connected to a power source with a voltage of 100 to 200 V) to a high voltage (usually 10,000 to 20,000 V, DC), and is held by an insulator 20. A high voltage is applied to the discharge wire holder 22 and the discharge wire 23. 2
1 is a holding cover. In addition, a ground electrode 24 is attached with a gap corresponding to the discharge wire 23,
A corona discharge is caused in the charging duct 25 to form an electric field area. A cover 15 that covers the entire charging section and serves as an attachment for the high-pressure generator 17 and a cover for the charging duct 25 is attached to the base 16, and its assembly order is as shown in FIG.

きるようになつている。 In addition, dust suction ports 2 are provided at both ends of the charging duct 25.
6. A discharge port 27 is formed, the diameter of which is approximately the same as the diameter of the suction port 8 of the dust collector 1. The hose connection part of the duct hose 10 is connected to the dust suction port 26, and the discharge port 27 is connected to the dust collector suction port 8 by a joint 9 or the like. Further, the duct hose 10 can also be connected to the suction port 8 of the dust collector 1.
以上の構成を有する集塵装置は次のようにして
使用される。 The dust collector having the above configuration is used in the following manner.
まず１μｍ以下の微細粉塵を吸引する場合は、
第１図に示すように使用する。この時吸引ダスト
１３は、荷電装置１４通過時に荷電され、荷電を

２に捕集されると同時に凝集粗大化し、目詰りを
生じることなく、高効率で捕集される。 First, when suctioning fine dust of 1 μm or less,
Use as shown in Figure 1. At this time, the suction dust 13 is charged when it passes through the charging device 14, and the fine particles are introduced into the dust collector while becoming coarser and growing due to contact between charged dust particles and mutual attraction collision due to Coulomb force, etc., and are further introduced into the dust collector. At the same time as the particles are collected in the 2nd layer, they aggregate and become coarser, and are collected with high efficiency without causing clogging.
一方、比較的粗大なダストを吸引する場合は、
荷電装置を取りはずし（図示せず）、ダクトホー
ス１０の接続部１１を直接、集塵機１の吸引口８
に接続し一般の集塵機として使用する。 On the other hand, when sucking relatively coarse dust,
Remove the charging device (not shown) and connect the connection part 11 of the duct hose 10 directly to the suction port 8 of the dust collector 1.
It can be connected to and used as a general dust collector.
フイルタの払い落し、および回収ダストの廃棄
は両者とも同一に、払い落しレバー６およびダス
トボツクス７の取出しによつて行なうことができ

荷電装置１４ではダスト１３に電荷を与えるの
みで、ダスト１３の捕集は行わない。単にダスト
１３に電荷を与えるだけなので、この荷電装置１
４を相当速い速度でダスト１３を含んだ空気を通
過させればよい。逆に遅い速度にした場合は荷電
装置１４内の接地極２４等にダスト１３が付着
し、好ましくない。そのため、本考案の一実施例
でこの速度は放電線２３に約20000ボルトの電圧
をかけた時約10〜20ｍ／sec程度にしている。 The charging device 14 only charges the dust 13 and does not collect the dust 13. This charging device 1 simply charges the dust 13.
4 may be passed through air containing dust 13 at a considerably high speed. On the other hand, if the speed is slow, the dust 13 will adhere to the ground electrode 24 and the like in the charging device 14, which is not preferable. Therefore, in one embodiment of the present invention, this speed is set to about 10 to 20 m/sec when a voltage of about 20,000 volts is applied to the discharge line 23.
又、このように比較的速い速度でダスト１３を
通過させる荷電装置１４はその流路断面積を極め

文でも述べた如く、荷電装置１４では単にダスト
１３に電荷を与えるだけで、主はあくまで、フイ
ルタ２で除塵するためである。 Further, the charging device 14 that allows the dust 13 to pass through at a relatively high speed can have a very small flow path cross-sectional area, and can be made extremely compact. For example, compared to an electrostatic precipitator that attaches dust 13 to the electrode plate, the volume is 1/10
It is possible to make the following small size. This is because, as mentioned in the preamble, the charging device 14 merely applies a charge to the dust 13, and the main purpose is to remove the dust using the filter 2.
かかる集塵装置によれば、次の作用を奏する。 According to such a dust collector, the following effects are achieved.
荷電装置１４は、荷電ダクト２５の通路全体

堆積することを防止できる。 In the charging device 14, the entire passage of the charging duct 25 has approximately the same ventilation area as the dust suction port 26,
In this charging duct 25, a grounding electrode 24, a discharge wire 2
3 is accommodated, the speed of the air passing through the charging duct 25 can be made very high, and it is possible to prevent the dust 13 from adhering to and accumulating on the ground electrode 24 and the like.

The dust suction port 26 of the charging duct 25 is connected to the dust collector 1.
The diameter of the suction port 8 is the same as that of the suction port 8, and the suction dust 1
Since the charging device 14 is detachably connected between the connection part of the dust hose 10 that suctions dust 3 and the suction port 8, when collecting dust with a large particle size, this charging device 14 can be removed. The dust hose 10 can be connected directly to the suction port 8 of the dust collector 1. In addition, a blurring device depending on the purpose can be installed between the charging device and the dust collector, and the usage can be further tailored to the purpose (for example, a blurring device with coarse mesh can be installed to further improve the clogging performance of the filtration type filter 2, etc.). ). Also, due to the nature of suction dust,
When it is desired to increase the charging time, it is easy to connect multiple charging devices, and the present invention has an extremely wide range of applications.
