Description

Technical Field

[0001] The utility model relates to the technical field of air purification, and more specifically refers to an electrostatic dust collection structure. Background Art

[0002] One of the conventional air purification methods is to use an electrostatic precipitator to purify the air. There are many related patents, which are not described here one by one. The electrostatic dust collecting structure of the conventional electrostatic precipitator generally includes a plurality of zero-potential side plates, a dust collecting plate and a high-voltage discharge electrode. Each of the zero-potential side plates is grounded and not charged. Each of the dust collecting plates is arranged in parallel between each of the zero-potential side plates. Each of the zero-potential side plates and the dust collecting plate is a metal plate body. The length of each zero-potential side plate is greater than that of each dust collecting plate. Each of the high-voltage discharge electrodes is a metal strip, which is arranged in parallel at one end of each of the zero-potential side plates. When the air passes through each of the high-voltage discharge electrodes and enters the ionization zone between each of the zero-potential side plates, the high-voltage discharge of each of the high-voltage discharge electrodes forms a corona effect in the ionization zone, which can dissociate the suspended particles in the air into positive ions and negative electrons. The positive ions have a larger kinetic energy and can travel between each of the dust collecting plates to be adsorbed and collected.

[0003] In the conventional electrostatic dust removal structure, the zero-potential side plate and the dust collecting plate are arranged in parallel, so the air flow path is straight. Through a certain length of the dust collecting plate and the air flow path, most of the suspended particle positive ions can usually be adsorbed by the dust collecting plate. However, even though the conventional electrostatic dust removal structure has a good efficiency in collecting suspended particles, the creator still created this "electrostatic dust collection structure" based on the spirit of continuous improvement, which can improve the plate absorption efficiency.

[0023] First, please refer to the first and second figures. The electrostatic dust collection structure 10 of a preferred embodiment of the present invention can be set in an air purification device or other equipment pipelines that require dust removal, and includes five zero-potential side plates 12, a plurality of dust collecting induction plates 14, four high-voltage discharge electrodes 16 and a plurality of fixing rods 18. Each of the zero-potential side plates 12 is a metal plate body arranged in parallel, each of the dust collecting induction plates 14 is a metal plate body, arranged in parallel between each of the zero-potential side plates 12, and the length is smaller than each of the zero-potential side plates 12. Each of the high-voltage discharge electrodes 16 is a metal strip, arranged in parallel at one end of each of the zero-potential side plates 12, and electrically connected to external power to discharge at high voltage. Each of the fixing rods 18 passes through each of the zero-potential side plates 12 and each of the dust collecting induction plates 14 to fix each of the zero-potential side plates 12 and each of the dust collecting induction plates 14. When air passes through each of the high-voltage discharge electrodes 16 and enters each of the zero-potential side plates 12, When the dust collecting induction plate 14 is in the air, the high voltage discharge of each high voltage discharge electrode forms a corona effect in the ionization zone, which can dissociate the particles in the air into ions (positive ions and negative electrons). Because the positive ions have greater kinetic energy, they can continue to move between the dust collecting induction plates 14 and be adsorbed; the above zero potential side plates 12, dust collecting induction plates 14, high voltage discharge electrodes 16 and fixed rods 18 are generally the same as the conventional electrostatic dust collecting structure, which is not the focus of this invention. The detailed structure, operation mode and detailed dust collecting actuation principle of each component will not be repeated here. The characteristics of this invention are:

[0024] Each of the zero-potential side plates 12 and each of the dust collecting induction plates 14 has two curved sections 22, 24, and a middle section 26, a front section 28, and a rear section 30 connected between and at both ends of the two curved sections 22, 24. The two curved sections 22, 24 form a plurality of curved flow channels 32 between each of the zero-potential side plates 12 and each of the dust collecting induction plates 14, and the cross-sections of the two curved sections 22, 24 can be generally C-shaped, ㄈ-shaped, or V-shaped, etc., but are not limited. Secondly, the curvatures of the two curved sections 22, 24 are oppositely arranged, so that the cross-sections of each of the zero-potential side plates 12 and each of the dust collecting induction plates 14 are generally S-shaped.

[0025] Each of the dust collecting induction plates 14 includes a plurality of zero potential dust collecting plates 34 and negative potential dust collecting plates 36. Each of the zero potential dust collecting plates 34 and negative potential dust collecting plates 36 is arranged in a staggered manner relative to each of the zero potential side plates 12 to be given zero potential and negative potential, and the two dust collecting induction plates adjacent to each of the zero potential side plates 12 are negative potential dust collecting plates 36.

[0026] In addition, a notch 38 is relatively recessed on one side of the middle section 26 of each negative potential dust collecting plate 36, and a grounding wire 40 passes through each zero potential side plate 12 and zero potential dust collecting plate 34 and crosses each notch 38 to be grounded, so that each zero potential side plate 12 and zero potential dust collecting plate 34 is not charged and has zero potential.

[0027] It further includes two side plates 19, which are relatively arranged on the outer sides of the two zero-potential side plates 12. Each fixing rod 18 is connected to the two side plates 19 to fix each zero-potential side plate 12, the dust collecting sensor plate 14 and the side plates 19. Each fixing rod 18 is made of non-conductive material, such as plastic material, but not limited to.

[0028] Thus, through the design of the two curved sections 22, 24 of each zero-potential side plate 12 and each dust-collecting induction plate 14, each zero-potential side plate 12 and each dust-collecting induction plate 14 can form each curved flow channel 32. When the air passes through each high-voltage discharge electrode 16 and enters between each zero-potential side plate 12 and is ionized, the positive ions of the particles in the air will enter each curved flow channel 32. Compared with the straight flow channel between the zero-potential side plate and the dust-collecting induction plate in the conventional electrostatic dust removal structure, the present invention can increase the chance of positive ions directly colliding with each dust-collecting induction plate 14, as shown in the third figure, and can indeed improve the adsorption efficiency of each dust-collecting induction plate 14 (rapid adsorption in a short time, especially adsorption by each negative-potential dust-collecting plate 36).

[0029] It must be mentioned that the bending sections of each zero-potential side plate and each dust collecting induction plate of the present invention are not limited to two, but can also be one bending section or three bending sections (including the above), and the bending direction of each bending section is not limited to the opposite direction mentioned above, but can also be the same direction. It only needs to increase the chance of positive ions directly colliding with each dust collecting induction plate, thereby improving the adsorption efficiency of each dust collecting induction plate, which meets the requirements of the present invention and belongs to the technical scope of the present invention.

[0030] In summary, the electrostatic dust collection structure provided by the present invention can form a plurality of curved flow paths between each zero-potential side plate and each dust collecting induction plate through the curved section structure of each zero-potential side plate and each dust collecting induction plate, thereby improving the efficiency of each dust collecting induction plate in adsorbing positive ions, and the dust removal effect is very good; therefore, the present invention does meet the requirements of a new utility model patent, and an application is filed in accordance with the law.

[0031] Although the present invention has been described above with reference to some embodiments, various modifications may be made thereto and parts thereof may be replaced by equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the various embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
