Problems solved by technology

However, this dust removal method has a disadvantage, that is, as the dust removal progresses, the electrostatic field plate will accumulate dust, and the dust will gradually increase, and the dust removal effect will gradually decrease, accompanied by secondary pollution of dust.
When electrostatic dust removal encounters oil fume, the sticky particles contained in it will firmly adhere to the electrode plate of the electrostatic field, which is very difficult to clean

Embodiment Construction

[0022] Such as figure 1 As shown, the water pump 4 in the circulating water system pushes the water in the water pipe 7 to flow in the water pipe 7 . Water flows on the water guide plate 5 from the upper end of the water guide plate 5, forms a water film 8 on the water guide plate 5, and the water of the water film 8 gathers downwards in the water tank at the lower end of the water guide plate. During the continuous circulation of the water flow, there is a circulating water film 8 on the water guide plate 7 .

[0023] A negative electrode needle 2 perpendicular to the water film 8 is provided at a distance from the water film 8 . The entire circulating water system is connected to the earth and has the same potential as the earth. The positive pole of the high-voltage power supply is connected with the positive electrode 3 in the water tank. The negative pole of the high-voltage power supply 1 is connected to the negative pole electric needle 2 .

[0024] Under the action...

Abstract

The invention provides an electrostatic precipitation circulating type water film dust removing device and method. The device and the method are characterized in that the top end of a negative electrode electric needle can perform corona discharge under the negative voltage effect to locally ionize air to generate an ionic field; an ionic field area generated by the corona discharge of the top end under the negative voltage effect contains a large number of negative ions which can perform directional movement in an electric field, thus generating ionic wind. According to the device and the method, the dust can be charged through the negative ions, and moreover, the negative ions can be accelerated to impact an electropositive water film under the combined action of coulomb force and the ionic wind; the running water forms a water film which can take away the dust; meanwhile, the negative ions can break protein structures of the surfaces of bacteria and virus, thus achieving the effect of eliminating bacteria and virus; a little ozone is generated inevitably during the corona discharge of the top end, and the solubility of ozone in water is several times that of oxygen, so that the ozone dissolved in the water film can continuously eliminate bacteria and virus in the water film.

Description

technical field [0001] The invention relates to a water film dedusting device and a related method thereof, belonging to the technical field of water film dedusting, in particular to a corona dedusting water film dedusting device and a method thereof. Background technique [0002] The basic principle of electrostatic dust removal is to use the electrostatic field to charge the dust particles and adsorb them on the electrostatic field plate. This dust removal method has the characteristics of high dust removal rate, wide range of dust removal particles, and small air resistance. However, this dust removal method has a disadvantage, that is, as the dust removal progresses, the electrostatic field plate will accumulate dust, and the dust will gradually increase, and the dust removal effect will gradually decrease, accompanied by secondary pollution of dust. When the electrostatic precipitator encounters oil fume, the sticky particles contained in it will firmly adhere to the e...
