Example Embodiment
[0017] Example 1 is as figure 1 As shown, the atomizing device 9 is composed of several two-fluid nozzles 3, two-fluid nozzle water supply pipelines 4, and two-fluid nozzle air supply pipelines 5, and is installed in the electrostatic precipitator 1 between the air inlet air distribution plate 2 and the primary electric field 6. During the time, the liquid containing electrolyte and surfactant from the two-fluid nozzle water supply line 4 and the air from the two-fluid nozzle air supply line 5 form a water mist liquid and spray into the primary electric field 6 under the action of the two-fluid nozzle 3. In the primary electric field 6, the corona is charged, and the charged droplets collide with the particles entrained in the flue gas. On the one hand, the water mist quenches the flue gas and improves the working condition of the electrostatic precipitator. The charged liquid of the surfactant collides with the particles in the flue gas to form wet particles, which effectivel...
Example Embodiment
[0018] Example 2 is as figure 2 As shown, the atomizing device 9 is composed of a two-fluid nozzle 3, a two-fluid nozzle water supply pipeline 4, and a two-fluid nozzle gas supply pipeline 5, and is installed between the final electric field 7 and the penultimate electric field in the electrostatic precipitator 1, The liquid containing electrolyte and surfactant from the two-fluid nozzle water supply line 4 and the air from the two-fluid nozzle air supply line 5 form a water mist liquid under the action of the two-fluid nozzle 3 and spray into the primary electric field 6, in the primary electric field 6 In corona charging, the charged droplets collide and contact the particles entrained in the flue gas. On the one hand, the water mist quenches the flue gas and improves the working condition of the electrostatic precipitator. On the other hand, it contains electrolytes and surface activation. The charged liquid of the agent collides with the particles in the flue gas to form ...
Example Embodiment
[0019] The difference between Embodiment 3 and Embodiment 2 is that the atomizing device 9 is installed between the penultimate electric field and the penultimate third electric field. Others are the same and will not be repeated here.
