In addition, the conventional electric dust collecting filter has a structure in which the ionization part and the dust collecting part are separated from each other, and has the following problems: the ionization part is provided with safety nets at the front and rear sides thereof, respectively, as safety devices for preventing the operator's hands from touching the discharge electrodes constituting the ionization part to cause obstruction, so that the ionization part is complicated in structure, and when the ionization part needs to be cleaned or repaired, the safety nets at the front and rear sides of the power part need to be completely separated, thereby deteriorating the workability.

Further, the conventional electric dust collecting filter has the following structure: the electric dust collector is provided with a pair of anode and cathode terminals for applying voltage to the ionization part and another pair of anode and cathode terminals for applying voltage to the dust collection part, so that the structure of connecting a power supply for applying voltage to the electric dust collector filter is complicated, the cost, the logistics cost and the management cost are increased, and the operation of connecting the power supply is complicated.

Further, according to the situation of the place where the electric dust collecting filter is installed, it is necessary to assemble and construct the electric dust collecting filter in a left-type mode and a right-type mode in consideration of the positions where air is sucked and discharged, but the conventional electric dust collecting filter has a structure that cannot be exchanged due to the difference in the arrangement direction of the components applied to the left-type mode and the right-type mode, and there is a problem that the assembling and the construction work corresponding to the environment of the place where the electric dust collecting filter is installed are inconvenient.

side surfaces

110a and 110b of the case 110. A left Type mark 116 (see fig. 6 a) indicating that the electrostatic precipitator filter is of a left Type (L-Type) is formed on the upper surface 110c of the housing 110, and a right Type mark 117 (see fig. 6 b) indicating that the electrostatic precipitator filter is of a right Type (R-Type) is formed on the bottom surface 110d of the housing 110.

Here, the left type is a type provided in a place where air flows from the left side to the right side, and indicates a type in which the ionization part I is disposed on the left side and the dust collection part 150 is disposed on the right side. The right type is a type provided in a place where air flows from the right side toward the left side, and represents a type in which the ionization part I is disposed on the right side and the dust collection part 150 is disposed on the left side.

The upper surface 110c and the bottom surface 110d of the housing 110 are formed with fasteners 115 and 115-1 for fitting to a cover 600 described later.

The counter electrode plate 130 is configured as a lattice-type plate and is disposed in front of the discharge electrode 120, and an air flow space S2 is provided between the lattices. The discharge electrode 120 is configured in such a manner that the tip thereof projects sharply toward the space S2 formed inside the lattice of the counter electrode plate 130. The opposite electrode plate 130 is electrically connected to the cathode terminal 112. Referring to fig. 7, a plurality of through holes 131 are formed at a predetermined pitch in the counter plate 130, and a plurality of fasteners 118 are formed at positions of the case 110 corresponding to the through holes 131.

A safety net 144 is coupled to the opening portion S1 of the support plate 140.

The conventional ionization part and dust collecting part are constructed in a separate structure such that safety nets are respectively provided at the front and rear of the ionization part, thereby having a problem of complicated structure, however, the ionization part I and dust collecting part 150 in the present application are integrated, so that it is sufficient to provide the safety net 144 only at the front of the ionization part I, and since a separate safety net is not additionally provided at the rear of the ionization part I, the construction of the apparatus can be simplified, and the number of safety nets to be separated when cleaning and maintenance work of the ionization part I is performed is reduced, thereby improving the convenience of work.

Fig. 4 to 6 illustrate a configuration in which the safety net 144 is omitted in order to identify the internal structure of the filter module 100.
