Example Embodiment

[0028] Hereinafter, the present invention will be described in further detail with the embodiment of the drawings as an example. The following examples are only descriptive and not restrictive, and the protection scope of the present invention cannot be limited by this.

[0029] An electrostatic agglomeration cyclone defogging device, such as figure 1 , figure 2 with image 3 As shown, the device includes an electrostatic agglomeration cyclone defogging unit 2 closely arranged in the tower 1. Each electrostatic agglomeration cyclone defogging unit includes a cylinder 5, a baffle plate 12, and a metal discharge wire 10. The cylinder body 11, the upper cylinder body 8, the high pressure ring 9, the nozzle 7, the guide vane 6, the guide vane and the guide plate can all be insulated, and the bottom of the cylinder body is provided with a guide plate coaxially. The plate can rectify the airflow entering the cylinder. The lower cylinder is coaxially arranged in the cylinder above the ...

Abstract

The invention relates to an electrostatic agglomeration cyclone demisting device. The device comprises electrostatic agglomeration cyclone demisting units which are tightly arranged in a tower, wherein each electrostatic agglomeration cyclone demisting unit comprises a cylinder, a guide plate, a metal discharge wire, a lower cylinder, an upper cylinder, a high compression ring, a nozzle and guide blades. According to the device, the ultimate grain size of the demister can be reduced, an effect of reducing the droplet concentration at the outlet of the demister is achieved, to-be-treated flue gas enters the device from bottom to top, and dust droplets in the flue gas are negatively charged while passing through the lower cylinder and agglomerate and grow up with positively charged spray mist while passing through the upper cylinder, so that the droplets in the flue gas are separated from the flue gas while passing through the guide blades according to the pneumatic cyclone principle.

Description

technical field [0001] The invention belongs to the technical field of environmental protection equipment, and relates to a flue gas demisting device at the outlet of an absorption tower in wet flue gas desulfurization technology, in particular to an electrostatic agglomeration swirling flow defogging device and its application. Background technique [0002] As the country pays more and more attention to environmental protection issues, the country has issued the most stringent flue gas environmental protection standards in history in 2015, one of which requires the dust concentration of the net flue gas outlet to reach 5mg / Nm 3 Next, in the existing wet desulfurization technology, the flue gas outlet carries a large amount of water, and the particles dissolved and suspended in the water are also entrained, which makes it difficult to meet the standards of this environmental protection standard. To solve this problem, the first thing to bear the brunt is to reduce the concen...
