Working principle
The wet electric dust collector directly sprays water mist onto the diverting electrodes and corona areas. The water is exposed in a powerful corona field formed by the rosehip electrode and disintegrates and is then sprayed. Here, the electric power of the electric field and the electric water mist. Interception, adsorption and condensation jointly play the role of capturing dust particles. After all, the dust particles are moved by the force of the electric field to reach the dust collection pole and be captured, unlike the dry electric dust collector, which raises the ash on the plate to the ash bucket by vibration, the wet electric dust collector will spray water on the dust collection plate, forming a continuous water film. The leaking water washes the trapped dust into the ash ladle to drain it into the water.
The dust removal process of the electrostatic dust collector can be divided into four stages: gas ionization, the dust receives ions and charges electricity, the electric dust moves to the electrode, the dust from the electrode is removed. Simply, objects of wet electrostatic dust removal include dust and dew drops. Since the physical characteristics of fog and dust droplets are different, the principle of their operation will be different accordingly. In principle, first of all, since the presence of water droplets affects the electrical discharge of the electrode, in order to form emitting ions, the free electrons in the metal electrode must obtain enough energy to overcome the ionization energy and cross the surface barrier to become the emitting electron.
The best location of the wet electric dust collector, which is terminal equipment for fine processing of complex pollutants in coal-fired power plants, is between wet desulfuration and the chimney.
The water resistance is relatively small. After the water droplets are combined with the dust, the resistivity of the high resistivity dust is reduced, so the working state of wet electrostatic dust removal will be more stable: again, since the wet electrostatic dust collector is washed with water flow, there is no vibration device, so that the secondary dust will not be generated, The wet electric dust collector will be anti-acid mist toxic heavy metals, and PM10 fine dust, especially PM2.5, have a good removal effect. Therefore, the wet electric dust collector can be used to control the SO3 acid mist of the power plant, and also has the prospect of joint removal of toxic heavy metals.
