Problems solved by technology

[0003] Such a method has been widely used. This method has the following problems: First, the conductive dust collecting plate needs to take into account the requirements of the wind resistance design and the electric field design at the same time, and its shape needs to take into account the requirements of the two fields, and it is often difficult in practice. Both; second, in order to avoid the air between the dust collection plates being broken down to produce high-voltage arcing, the distance between the dust collection plates is greatly restricted, and it is difficult to apply to the limited volume scheme

Embodiment 1

[0035] Such as figure 1 It is a schematic diagram of a side view of an embodiment of the present invention; figure 2 yes figure 1 Schematic illustration of the working principle of the illustrated embodiment, with details of the dust collection plate; image 3 yes figure 1 The bottom view of the dust collecting plate of the embodiment.

[0036] The dust collecting device 100 has dust collecting plates distributed in an array at intervals; for the convenience of description, the parts from the top to the first dust collecting plate 110 and the second dust collecting plate 120 will be described. The adjacent first dust collecting plate 110 and the second dust collecting plate 120 have a unidirectional electric field between each other, and a first dust removing air duct 130 crossing the electric field;

[0037] There is a fan device 200 on the front air flow path of the dust collecting device 100, which makes the air to be dedusted form a unidirectional controllable air flo...

Embodiment 2

[0042] Such as Figure 4 It is the bottom view of the dust collection plate of embodiment two; the overall structure of embodiment two is similar to embodiment one, the difference is that it is the dust collection plate at first, for the convenience of comparison, the first dust collection plate 110 of embodiment two is also taken out Compare. With image 3 Compared with the first dust-collecting plate 110 of the first embodiment shown, the first dust-collecting plate of the second embodiment has a larger empty section X, while the relative area of ​​the first conductive plate 112 is smaller, and the present embodiment The first dust collecting plate 110 is a printed circuit board made of CEM1. The processing of the first dust-collecting plate 110 of this structure is very easy, whether it is the processing of the shape or the etching of the first conductive electrode plate 112 in the form of the copper-clad surface, it can be realized with a very mature process at a relativ...

Embodiment 3

[0045] Such as Figure 5 , is a schematic side view of the third embodiment; the dust collecting device 100, the blower device 200 and the high-voltage emitting head 301 in this embodiment are all the same as in the first embodiment; The negative pressure makes the air to be dedusted together with the charged particles 400 firstly sucked into the dust collecting device 100 , and then output as clean air 500 through the fan device 200 . This solution is suitable for occasions with a lot of dust, and can better protect the life of the fan device 200 .

Abstract

The invention discloses a structure of an electrostatic dedusting device. The structure is characterized by comprising a dust collection device, a fan device and a corona device, wherein the dust collection device is provided with dust collection plates which are distributed at intervals in an array mode; a single-way electric field and a dedusting air duct which traverses the electric field arranged between the adjacent dust collection plates; each dust collection plate comprises an insulation substrate and a conducting plate which is in close fit with the surface of the insulation substrate; by the fan device, air to be dedusted forms single-way controllable air flow, and the air flow penetrates through the dedusting air duct; the corona device is provided with a high-pressure emission head for electrifying dust particles in the air flow controlled by the fan device. According to the dedusting device with the structure, the dust collection plates comprise insulation substrates and conducting plates which are in close fit with the surfaces of the insulation substrates, so that the pneumatic design and electric field design of the dust collection device can be separated to avoid mutual influence; and resistance among the conducting plates is improved, and arcing is avoided, so that the optimized dedusting performance and the applicability on different occasions are realized finally.

Description

technical field [0001] The invention relates to a structure of an electrostatic precipitator. Background technique [0002] At present, the general commercially available electrostatic precipitator, its working principle is to set a one-way flow air duct to collect the air to be purified, the air duct is preceded by a metal discharge electrode, and the dust in the air is made Particles are charged; a dust collector with an electric field is installed behind the air duct to collect the suspended particles in the air in the air duct. Usually, the form of the dust collection device is conductive dust collecting plates spaced apart from each other, such as metal plates arranged in parallel; there is an electric field between the metal plates, so that the charged dust particles flowing between the plates are deflected by the Coulomb force in the electric field , and finally trapped on the plate of the dust collection device, so that the dust particles in the air that finally flo...
