The present invention relates to an electric dust collecting filter having a function of preventing contamination of a high voltage insulating element and an electric dust collecting device having a fire fighting function, and specifically, to prevent contamination of a high voltage insulating element in order to maintain insulation performance between a dust collecting electrode and a discharge electrode. The present invention relates to an electric dust collecting device having a fire fighting function by forming a vibration electric dust collecting filter and a plurality of dust collecting filters connected to each other.

An electric dust collecting device refers to a device that collects dust charged with negative or positive charges by making the dust collecting electrode an anode and a discharge electrode to become a cathode. In general, for dust collection, a high voltage is applied between the dust collecting electrode and the discharge electrode to generate an unequal electric field by corona discharge, so that charged dust or gas is collected by the electrostatic force in the dust collecting electrode. The electrostatic precipitator can be applied to large workplaces with a large amount of dust or gas due to high discharge electrodes, as well as workplaces in which dust or fine foreign matter acts.

When the electrostatic precipitating filter is operated, dust or foreign matter may be continuously accumulated and the foreign matter may be removed through a cleaning process. However, if foreign substances are introduced during the dust collection process, the amount of foreign substances accumulated in an insulating element such as a high voltage insulator exposed to the discharge electrode of the dust collecting filter may increase. In addition, foreign substances in liquid form flow to the high voltage insulator through various paths, thereby reducing the dust collection performance or causing an abnormal discharge phenomenon, which may cause an operation error of the dust collection filter or cause a fire due to abnormal discharge. Therefore, in order to solve this problem, it is necessary to prevent the inflow and accumulation of foreign substances into an insulating element such as a high-voltage insulator that separates the dust collecting electrode and the discharge electrode. The prior art does not disclose such an insulator structure. In addition, in order to design a large-capacity dust collector, it is necessary to connect a plurality of dust collectors to each other.
