China's environmental protection inspectors will become the norm in the future, and the nationwide green storm is intensifying. The wood processing industry is a low-end of traditional building materials occupations, and the environmental protection of equipment is upgraded. In the meantime, the boiler is one of the important sources of smoke and dust emissions. The impact on the atmospheric environment is huge, and it has become the main point of factory renovation and supervision. Let's take a look at the technical transformation plan of the boiler dust removal equipment.
Boiler Dust Removal Equipment Technical Transformation Scheme I. Equipment composition and principle:
The wet electrostatic precipitator is generally composed of the cabinet, the gray water treatment circulation system, and the electric control system. The deposition electrode is a plate-type ribbed structure on both sides. A discharge electrode structure is arranged between the deposition electrode rows, and a horizontal structure is arranged inside the discharge electrode structure. Perhaps the electrode wire is placed vertically, and the electrode wire is a needle wire.
During operation, a high voltage is applied between the discharge electrode and the deposition electrode in the housing of the wet electrostatic precipitator, forming an uneven high-voltage electric field, and ionizing the gas therebetween to generate electrons, anions, and cations. SO2 及其他污染物凝并增湿。 When the flue gas to be processed enters an electric field full of water mist, the dust, SO2 and other pollutants in the flue gas are condensed and humidified. SO2 和污染物荷电，然后在电场力的作用下向极性相反的电极移动并沉积在电极上释放出电荷。 Because of the collision and dispersion of ions, water mist, dust, SO2 and pollutants are charged, and then move to the opposite polarity electrode under the action of electric field force and deposit on the electrode to release the charge. Regular spraying makes the captured dust flush out into the ash hopper.
The spray water for wet electrostatic precipitators is generally selected from tap water or partially recycled neutral water. The grey water collected from the ash bucket enters the recycling and reuse system. After being clarified, filtered and neutralized by adding alkali, the clean water is recycled and reused. The reused system periodically discharges a part of the wastewater and then makes up the raw water. It is then pumped into the wet electrostatic precipitator by the circulating pump for intermittent spraying.
