However, the metal materials resistant to strong acid or strong base are heavy and difficult to handle, which is a problem for the practitioner. Alternatively, the practitioner may choose a lighter weight metal material, such as aluminum, which, however, is not resistant to strong acids or bases. After cleaning and maintenance for many times, the aluminum electrode plates are corroded and become thin, and gaps are formed between the aluminum electrode plates and the supporting frames for fixing the electrode plates, so that shaking and noise are generated when the electrostatic electrode plates are combined and operated.

More alternatively, referring to fig. 3, another first conduction plate 14 and another second conduction plate 16 are added and combined with the fourth surface 124 of the frame body 12 in the manner described above.

The high voltage set 20 is disposed in the internal space S1, and has a plurality of electrode lines 22 and at least one first fixing bar 24.

Referring to fig. 4, fig. 4 is a top view of an electrode plate 32 shown in fig. 3. The electrode plate 32 of the low voltage set 30 has a core plate 321 and a metal layer 322 covering the core plate 321. The core plate 321 is a non-metal material, and the non-metal material includes plastic and has a high temperature resistance. The class of plastics in turn comprises polyethylene terephthalate (PET), High Density Polyethylene (HDPE), polyvinyl chloride (PVC), Low Density Polyethylene (LDPE), Polystyrene (PS), polypropylene (PP), polycarbonate resin (PC), polylactic acid (PLA) or combinations thereof. The material of the metal layer 322 includes copper, chromium, stainless steel or a combination thereof, and has a property of resisting corrosion of strong acid or strong alkali. The metal layer 322 is attached to the surface of the core plate 321 by electroplating, chemical plating, attaching, chemical vapor deposition or physical vapor deposition. The electroplating is to immerse the core plate 321 in a solution containing metal ions, and deposit the metal layer 322 on the surface of the core plate 321 after the metal ions are reduced and precipitated by using the principle of electrochemistry. The electroless plating is to dip the core substrate 321 in a plating solution containing metal ions, and deposit the metal ions on the surface of the core substrate 321 by utilizing the self-redox reaction between the metal ions and the surface of the core substrate 321 to form the metal layer 321. The attaching means to attach the prepreg having the metal layer 322 to the surface of the core board 321, so that the metal layer 322 having conductivity is attached to the surface of the core board 321. Chemical vapor deposition refers to the chemical reaction of a gaseous reactant containing the material of the metal layer 322 with the surface of the core 321 to form the metal layer 322. The pvd is to evaporate a target material having a metal layer 322 by a physical discharge technique under a vacuum condition, and deposit the evaporated target material on the surface of the core plate 321 under the action of an electric field to form the metal layer 322. However, the method of attaching the metal layer 322 to the core 321 is not limited to the foregoing.

Referring to fig. 4, each of the electrode plates 32 has a first thickness D1, and each of the core plates 321 has a second thickness D2. The first thickness D1 of the electrode plate 32 is between 0.7 and 1.2 cm, and the second thickness D2 of the core plate 321 is between 0.6 and 1.1 cm. Preferably, the first thickness D1 of the electrode plate 32 is between 0.8 and 1.0 cm, and the second thickness D2 of the core plate 321 is between 0.8 and 0.9 cm. The first thickness D1 and the second thickness D2 of the electrode plates 32 are designed such that if the second thickness D2 is less than 0.6 cm, the excessively thin second thickness D2 would cause a practitioner to insert too many electrode plates 32 to keep a proper distance between any two adjacent electrode plates 32, which would otherwise cause inconvenience in assembly; if the second thickness D2 is greater than 1.1 cm, air is easily blocked from passing through the gaps between the electrode plates 32, resulting in inefficient air purification and, in addition, unnecessary weight increase. The range of the first thickness D1 of the electrode plate 32 is designed such that the specific gravity of the entire electrode plate 32 is lighter than that of the conventional completely metallic electrode plate, and the entire weight is reduced.

As shown in fig. 5 to 9, the aforementioned electrostatic electrode plate assembly 100 is applied to an electrostatic decontamination apparatus 400, but the electrostatic decontamination apparatus of the present invention can be installed with other types of electrostatic electrode plate assemblies, not limited to the aforementioned electrostatic electrode plate assembly 100. In fig. 5 to 9, the electrostatic decontamination apparatus 400 further includes a housing 410, a first filter 420, a second filter 430, and a power control assembly 440, and is illustrated by the electrostatic electrode plate assembly 100.

The housing 410 has an accommodating space S2 therein, and includes an opening 410a, an air inlet 410b and an air outlet 410c, wherein the air inlet 410b and the air outlet 410c are disposed opposite to each other and respectively communicate the outside of the housing 410 with the accommodating space S2. The housing 410 is made of a non-metallic material, including plastic. The class of plastics in turn comprises polyethylene terephthalate (PET), High Density Polyethylene (HDPE), polyvinyl chloride (PVC), Low Density Polyethylene (LDPE), Polystyrene (PS), polypropylene (PP), polycarbonate resin (PC), polylactic acid (PLA) or combinations thereof. The inner wall 412 of the housing 410 has a metal film (not shown).

The electrostatic electrode plate assembly 100 is disposed in the accommodating space S2. The first opening 121a of the first surface 121 of the frame 12 corresponds to the air inlet 410b, the second opening 122a of the second surface 122 corresponds to the air outlet 410c, and the third surface 123 corresponds to the opening 410 a.

The first filter 420 and the second filter 430 are disposed in the accommodating space S2. The first filter 420 is disposed between the air inlet 410b and the high voltage group 20 of the electrostatic electrode plate assembly 100, and the second filter 430 is disposed between the air outlet 410c and the low voltage group 30 of the electrostatic electrode plate assembly 100.

As shown in fig. 5 to 7, the power control assembly 440 has a cover 441, a high voltage conductive element 442, and a low voltage conductive element 443. The cover 441 is pivotally disposed on the housing 410, and can be operated to close the opening 410a of the housing 410 or open the opening 410a to expose the opening. The high voltage conductive device 442 and the low voltage conductive device 443 are insulated from each other, and the high voltage conductive device 442 and the low voltage conductive device 443 are disposed on the side surface of the cover 441 corresponding to the opening 410a and insulated from the cover 441. More specifically, the power control assembly 440 has a plurality of insulators 444, and the number of the insulators 444 is two in the present embodiment. The high voltage conductive member 442 and the cover 441 are insulated from each other by one of the two insulators 444; the low-voltage conductive member 443 and the cover 441 are insulated from each other by the other of the two insulators 444. The insulation system is used to avoid the phenomena of corona or noise generated when the conductive component and the cover body are fused due to resistance short circuit or gas failure generated by voltage. The power control assembly 440 includes an electronic control module 445. The electronic control module 445 is electrically connected to an external power source (not shown) and has a high voltage generator 445a and a low voltage generator 445b, as shown in fig. 8, the high voltage generator 445a and the low voltage generator 445b are insulated from each other, the high voltage generator 445a is electrically connected to the high voltage conductive member 442, and the low voltage generator 445b is electrically connected to the low voltage conductive member 443. In this embodiment, the electronic control module 445 is disposed inside the cover 441.

Referring to fig. 8 and 9 again, when the housing 410 is manipulated to close the opening 410a, the high voltage conductive member 442 abuts against the first conducting plate 14, so that the high voltage generator 445a is electrically connected to the first conducting plate 14; the low voltage conductive member 443 will abut against the second conduction plate 16, so that the low voltage generator 445b and the second conduction plate 16 are electrically connected. As will be described in detail below, after the air enters the accommodating space S2 from the air inlet 410b of the housing 410, the air is primarily filtered by the first filter screen 420, fine particles in the air pass through the gaps between the electrode wires 22 of the high voltage group 20, and the fine particles become charged particles under the voltage of the high voltage group 20, the charged particles move from the high voltage group 20 to the low voltage group 30, the charged particles are adsorbed on the surfaces of the electrode plates 32 of the low voltage group 30, and the air without charged particles passes through the gaps between the electrode plates 32, and then passes through the second filter screen 430 and leaves the accommodating space S2 from the air outlet 410c, thereby completing the air purification.

In summary, the electrode plate 32 of the electrostatic electrode plate assembly 100 of the present embodiment is designed to have a core plate 321 and a metal layer 322 covering the core plate 321. The core plate 321 is made of a non-metal material, such as various common plastics, which helps to reduce the weight of the electrode plate 32, and thus greatly reduce the weight of the electrostatic electrode plate assembly 100 or the electrostatic discharge apparatus 400 including the electrostatic electrode plate assembly 100. The metal layer 322 is made of a metal material resistant to strong acid or strong base, such as copper, chromium, stainless steel or a combination thereof, so that when a practitioner cleans and maintains the plurality of electrode plates 32, there is no need to worry about the electrode plates 32 becoming thinner due to the strong acid or strong base cleaning solution corroding the plurality of electrode plates 32. Compared with the conventional aluminum electrode plate, the electrode plate 32 of the present embodiment has a longer service life. In addition, the housing 410 of the electrostatic discharge apparatus 400 is made of a non-metallic material, such as various common plastics. Compared with the existing shell made of metal materials, the shell made of non-metal materials is lighter, the labor cost of cleaning, maintaining or carrying processes of a practitioner is reduced, and the joints of the components of the existing metal shell are connected in a manual spot welding mode, so that a large amount of labor and time are consumed; the housing 410 of the present embodiment does not have the above disadvantages, and only needs to be manufactured by opening the mold, i.e. integrally formed, which is helpful for the practitioner to improve the production efficiency.

The above description is only a preferred embodiment of the present invention, and all equivalent changes and modifications to the application of the present invention and the claims should be considered to be included in the scope of the present invention.
