The insulator 10 is provided so that the discharge electrode 30 and the dust collecting electrode 40 can maintain the insulation resistance. The insulation resistance of the insulator 10 is reduced from condensation and steam generated by the introduced gas and temperature difference, Dust, and moisture by supplying a heat source and air to the insulator 11 by the blower P to protect the insulator 10 from the dust and moisture.

However, when the insulator 10 is installed outside the cooling tower and the electrostatic precipitator, the main hanger beam 20 and the auxiliary hanger beam 21 are struck downward by the weight of the plurality of discharge electrodes 30, there was.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and it is an object of the present invention to provide a water hose insulator provided inside the electrostatic precipitator, which can prevent the main hanger beam from being deformed by the weight of the discharge electrode, The purpose of this paper is to provide

Another object of the present invention is to provide a moisture barrier insulator provided inside the electrostatic precipitator which can stably maintain insulation by preventing water vapor generated through corona discharge from contacting the insulator.

The waterproofing insulator provided inside the electrostatic precipitator according to the present invention is characterized in that in the insulator provided in an electrostatic precipitator in which a plurality of discharge electrodes and a collecting electrode are coupled to the lower side of the main hanger beam, Wherein a plurality of insulators are spaced apart above the dust collecting pole so as to be able to support the main hanger beam so as to prevent the main hanger beam from being bent and deformed, And a water blocking cover is coupled to the lower end of the insulator so as to block the discharge pin coupled to the outer circumferential surface of the discharge electrode and the water vapor generated by the dust collecting pole from contacting the surface of the insulator .

Preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The insulator 10 of the present invention is installed inside an electrostatic precipitator installed in a power plant, a steel mill, a cement plant, a steam production boiler facility, a cooling tower, an incinerator, etc. In the present invention, The insulator 10 is provided inside the electrostatic precipitator and the insulation resistance can be maintained by adding a constitution that can block moisture to the outside of the insulator 10.

The insulator 10 is installed inside the electrostatic dust precipitator as shown in FIG. 4, and a plurality of insulators 10 are interposed between the main hanger beam 20 and the dust collecting electrode 40 at an interval.

The insulator 10 prevents the main hanger beam 20 from being bent and deformed by the weight of the plurality of discharge electrodes 30 by supporting the main hanger beam 20 on the upper side of the dust collecting pole 40, The insulator 10 can support the weight of the discharge electrode 30 applied to the main hanger beam 20 by adjusting the length and the size of the electrostatic precipitator and the length and the number of the discharge electrode 30, have.

In this case, since the insulator 10 is installed inside the electrostatic precipitator, it is possible to prevent deformation by supporting the main hanger beam 20. However, since the corona discharge of the discharge electrode 30 charges the water vapor, Water may contact the surface of the insulator 10 due to the nature of the wet electrostatic precipitator to collect the water droplet particles. As a result, the insulation may be destroyed, resulting in problems such as deterioration of equipment performance, grounding phenomenon, and failure due to high voltage power.

5, the water shutoff cover 60 is coupled to the lower end of the insulator 10, and the water shutoff cover 60 is coupled to the upper end of the insulator 10, It is possible to block the moisture that comes into contact with the liquid.

That is, the water fall blocking lid 50 prevents the water vapor generated by the corona discharge from falling on the surface of the insulator 10 after the water droplets are formed on the surface of the main hanger beam 20, And the moisture blocking cover 60 closes the outer side of the insulator 10 to block moisture that comes into contact with the surface of the insulator 10 in a water vapor state.

At this time, the upper and lower sides of the moisture barrier cover 60 are hermetically sealed so as to block the water flowing into the upper and lower sides, and a gap D is formed between the water barrier cover 50 and the moisture barrier cover 60 Respectively.

The distance D formed between the water fall blocking lid 50 and the water blocking cover 60 is for maintaining insulation and is set to be lower than the distance D between the water shutoff cover 60 and the water shutoff cover 60 due to the water flowing through the water shutoff lid 50 .

The distance D between the water fall blocking lid 50 and the water blocking cover 60 is preferably smaller than the distance d between the discharge pin 31 and the dust collecting pole 40 where the corona discharge is generated It is preferable to form it wide.

6, a heater 70 is coupled to the lower end of the insulator 10, and the heater 70 is connected to the inside of the moisture barrier cover 60, Thereby evaporating the fine water vapor and moisture, thereby making the insulation more stable.

In addition, a coating film is formed on the surface of the insulator 10 for more perfect insulation so that critical surface tension is minimized, so that even if water vapor contacts the surface of the insulator 10, So that grounding can be prevented.

In this case, the coating film can minimize critical surface tension by forming an oil film by spray nano coating using silicone oil.

Therefore, the water blocking insulator provided inside the electrostatic precipitator according to the present invention is connected to the main hanging beam 20 by a plurality of insulators 10 so as to support the main hanger beam 20, And the water shutoff cover 60 and the water shutoff cover 60 installed outside the insulator 10 can prevent the deformation of the water shutoff cover 60 and the water shutoff cover 60. Therefore, Can be extended.
