Dust collector that removes dust floating in the air and uses volume expansion of gas (so-called dust chamber), dust collector that uses centrifugal force (so-called cyclone dust collector), dust collector that uses filter (so-called filter dust collector) or Dust collectors that utilize electric Coulomb force (so-called electric dust collectors) are widely used.

ーを支持する構成の例を模式的に示す断面図である。The electrostatic precipitator has a discharge electrode and a dust collecting electrode, the dust collecting electrode is connected to the ground through the main body of the electrostatic precipitator, and the discharge electrode is electrically insulated from the main body of the electrostatic precipitator.
In this way, voltage is applied to the discharge electrode to cause corona discharge,
The dust is charged with negative ions and adsorbed on the dust collecting electrode by Coulomb force. The bus bar that supplies power to the discharge electrode is usually hung from above the ceiling of the electrostatic precipitator (hereinafter referred to as the dust collector ceiling). FIG. 2 is a cross-sectional view schematically showing an example of a conventionally known configuration for supporting a bus bar.

れる。The bus bar 1 is fixed to a support member 4 arranged above the dust collector ceiling 2 via an insulator 3. On the other hand, a through hole 7 having a diameter larger than that of the bus bar 1 is provided at a position where the bus bar 1 penetrates the dust collector ceiling 2, and the bus bar 1 is hung so as not to contact the dust collector ceiling 2. Further, the lower part of the bus bar 1 is connected to a discharge electrode (not shown), and the discharge electrode is suspended inside the electrostatic precipitator. In this way, the discharge electrode is electrically isolated from the electrostatic precipitator body.

の成分を含有している。That is, since there is a gap between the outer surface of the bus bar 1 and the inner surface of the through hole 7, dust and the like floating inside the electric dust collector leaks above the dust collector ceiling 2 through this gap. Therefore, an insulator box 5 that covers the bus bar 1, the insulator 3, the support member 4, and the through hole 7 is provided to prevent dust from being diffused into the atmosphere. For example, when using an electric precipitator to remove dust from exhaust gas in an exhaust gas purification process of a sulfuric acid manufacturing plant that recovers SO 2 contained in by-product gas of a flash smelting furnace or converter used in copper smelting as sulfuric acid. In addition to dust, mist-like water (so-called mist) floats in the exhaust gas, and the mist contains corrosive components.

分的に腐食され、開口部が生じる。Therefore, it is necessary to provide the insulator box 5 to prevent the dust and mist from being diffused into the atmosphere, and to prevent the dust and mist from entering the insulator box 5. The reason is that dust and mist enter the insulator box 5 to cause various problems as described below. (a) Since the dust attached to the insulator 3 is energized, the bus bar 1 is not charged to a predetermined voltage, and the dust collection efficiency is reduced. (b) Since the sparks are repeatedly generated in the portion where the dust is attached, the insulator 3 is damaged. (c) The insulator box 5 is partially corroded due to the attachment of the mist, and an opening is formed.

る。Therefore, as shown in FIG. 2, an oil seal 6 and an insulating seal member 8 are used to prevent dust and mist from entering the insulator box 5. However, with this technique, it is inevitable that the oil of the oil seal 6 evaporates and scatters and adheres to the entire insulator 3 because the exhaust gas from the flash smelting furnace or the converter that is processed in the sulfuric acid manufacturing plant has a high temperature. When oil adheres to the entire insulator 3, sparks are repeatedly generated at a certain place where oil or dust adheres, so that the insulator 3 is damaged and current cannot be supplied.

に行なわなければならない。In order to prevent the insulator 3 from being damaged, an operator generally cleans the insulator 3 to remove the oil attached to the insulator 3. However, when cleaning by workers,
Not enough oil can be removed. Therefore, when the insulator 3 is damaged, it is replaced and operated again. On the other hand, in order to sufficiently remove the oil attached to the insulator 3, cleaning must be performed frequently.

Moreover, when performing maintenance and inspection work, it is necessary to stop the corresponding electrostatic precipitator among the electrostatic precipitators operating in parallel with a plurality of units, which affects the operation of the flash furnace and the converter. In order to solve such a problem, it is necessary to prevent the oil of the oil seal 6 from adhering to the insulator 3.

This is a method of preventing insulator damage by blowing hot air. In the invention described above, as a preferred embodiment,
After blowing hot air that preheated the atmosphere and nitrogen gas to the insulator,
It is preferable to discharge the hot air by shifting the cores of the blowing position and the discharging position so that the hot air uniformly hits the insulator, and it is particularly preferable to discharge the hot air from above the blowing position.

The bus bar 1 is fixed to a support member 4 arranged above the dust collector ceiling 2 via an insulator 3. On the other hand, at a position where the bus bar 1 penetrates the dust collector ceiling 2, a through hole 7 having a diameter larger than that of the bus bar 1 is provided, and the bus bar 1 is attached to the dust collector ceiling 2
It is hung so that it does not come in contact with. Busbar 1
Is connected to a discharge electrode (not shown), and the discharge electrode is suspended in the electrostatic precipitator. In this way, the discharge electrode is electrically isolated from the electrostatic precipitator body.

分で、碍子ボックス５内に粉塵等が侵入して充満する。Since there is a gap between the outer surface of the bus bar 1 and the inner surface of the through hole 7, the bus bar 1, the insulator 3, and the support member 4 are provided.
Further, the insulator box 5 covering the through hole 7 is provided to prevent dust and mist from being diffused into the atmosphere, and the oil seal 6 is provided at the bottom of the insulator box 5. In order to electrically insulate the discharge electrode from the main body of the electrostatic precipitator, it is necessary to provide a gap between the inner surface of the member forming the oil seal 6 and the outer surface of the bus bar 1. Therefore, an insulating seal member is provided in the gap. 8 is filled to prevent dust and mist from entering the insulator box 5, but this is not enough and dust and the like enter the insulator box 5 and are filled.

のである。Then, in order to prevent the oil in the oil seal 6 from evaporating and becoming an oil mist and adhering to the inner surface and the outer surface of the insulator 3, the insulator 11 is filled in the space between the outer surface of the bus bar 1 and the inner surface of the insulator 3. And, hot air is blown to the outer surface of the insulator 3. In other words, the insulator 11 prevents oil from adhering to the inner surface of the insulator 3, evaporates the oil adhering to the outer surface of the insulator 3 by hot air, and discharges dust and the like that have entered the insulator box 5 to the outside of the insulator box 5. Let them do it.

い。The hot air temperature is 35 to 80 ° C., preferably 35 to 60
℃, more preferably about 40 ℃ is good. Higher temperature is better for drying, but insulator is damaged if it is too high. Also, raising the temperature increases power consumption.
On the other hand, when the temperature is low, the effect of preventing oil adhesion decreases. The amount of hot air blown onto the insulator may be determined according to the size of the insulator box 5 and the state of adhesion of oil and dust.

たオイルを蒸発させる効果が向上するからである。By thus preventing the oil and dust of the oil seal 6 from adhering to the inner surface and the outer surface of the insulator 3, it is possible to prevent the insulator 3 from being damaged due to the adhesion of the oil or the like. In the present invention, since the insulator 3 is covered with the insulator box 5, the blower pipe 9 is arranged in the insulator box 5 to blow hot air to the insulator 3. On the other hand, an exhaust pipe 10 is arranged to exhaust hot air from the insulator box 5. However, it is preferable that the position where the exhaust pipe 10 is arranged is above the position where the blower pipe 9 is arranged. The reason is that the hot air rises along the outer surface of the insulator 3 to improve the effect of evaporating the oil attached to the outer surface of the insulator 3.

Thus, while recovering SO 2 as sulfuric acid from the by-product gas of the flash furnace and the converter, the sulfuric acid manufacturing plant was operated for 3 months. Furthermore, in order to remove dust and mist from the exhaust gas discharged from the sulfuric acid manufacturing plant,
The electrostatic precipitator was operated while maintaining the load voltage at 40 kV or higher.

As a result, cleaning was not required in the invention example, whereas it was generated 20 times in the comparative example (required time was 0.5 hour on average). In all of the 20 cleanings performed in the comparative example, the oil of the oil seal 6 and the leaked dust or mist adhered to the insulator 3 in all cases.
