While meeting the new standard, the wet electrostatic precipitator can also control the haze fine particles, sulfur trioxide aerosol droplets, organic pollutants, heavy metal pollutants, etc., which has great social benefits. The air pollutant control mode of SCR+ESP/FF+WFGD+WESP is also a relatively effective way to control pollutants in Shangshan Coal fired Power Plant. Electrostatic wet precipitator manufactor Common dust control technologies, among which the dry electrostatic precipitator, the electrostatic fabric composite precipitator and the bag type precipitator are used as the front section dust control technology, cannot guarantee the ultra clean emission of flue gas dust after the desulfurization device, while the wet electrostatic precipitator arranged at the downstream of the wet desulfurization device will be used as a reliable terminal dust control technology. The working principle of wet electrostatic precipitator is similar to that of dry electrostatic precipitator. It is high-voltage corona discharge that charges dust or water mist, and charged particles reach the dust collecting plate under the action of electric field force, customized Electrostatic wet precipitator However, in terms of the way of dust, the dry electrostatic precipitator uses mechanical vibration, while the wet electrostatic precipitator uses flushing fluid to flush electricity, washing the dust captured on the dust collection plate into the ash hopper and then discharging the wet electrostatic precipitator. The advantages of the wet electrostatic precipitator are: because the mass and heat transfer processes occur simultaneously in the process of gas and liquid contact, this type of precipitator has the function of dust removal, It also has the function of flue gas cooling and absorption of harmful gases. Suitable for high temperature.

Electrostatic wet precipitator manufactor Different types of dust remover equipment have their own precautions. When we usually use the dust remover equipment, we should tell my customer friends some application matters. What matters should we consider when using wet electrostatic precipitator? Matters needing attention on the application of wet electrostatic precipitator. 1. The wet electrostatic precipitator shall be put into the insulator chamber electric heating and hot air purging system at least 8 hours in advance to ensure that the temperature of the insulator chamber is more than 60 ℃. 2. The wet desulfurization system of the wet electrostatic precipitator is put into operation early to prevent dry and high-temperature smoke from entering the wet electrostatic precipitator, which will lead to scaling of internal parts and damage of internal anti-corrosion coating. three customized Electrostatic wet precipitator The wet dust collector can be opened when the following three conditions are met together: 3.1 The wet electrostatic precipitator is operated with 25% of the oil gun remaining and 35% of the powder feeding is normal and stable or the oil gun is completely withdrawn. 3.2 The temperature of flue gas entering the wet electrostatic precipitator is lower than 70 ℃. 3.3 Desulfurization equipment has been opened. 4. The process of opening the wet electrostatic precipitator: first open the low-pressure water supply system and then the high-pressure power supply system.

Main working principles of wet electrostatic precipitator: customized Electrostatic wet precipitator Spray the water mist to the discharge electrode and corona area, the water mist will split and further atomize after being charged in the powerful corona field formed by the barbed electrode, and the collision interception, adsorption and coagulation of electric field force and charged water mist will jointly trap the dust particles, and finally the dust particles will reach the dust collector under the drive of electric field force and be trapped. The water forms a continuous water film on the dust collecting electrode, and the captured dust is washed into the ash hopper and discharged with water. Operating principle of wet electrostatic precipitator. The dedusting process of electrostatic precipitator can be divided into four stages: gas ionization; The dust is charged with ions; Charged dust moves towards the electrode; Remove the dust on the electrode. Only the objects removed by wet electrostatic precipitation are dust and droplets, but their working principles are different due to the differences in physical characteristics between droplets and dust. In principle, Southwest Guizhou Electrostatic wet precipitator First of all, the existence of water droplets has an impact on the electrode discharge. To form emitting ions, free electrons in the metal electrode must obtain enough energy to overcome the ionization energy and cross the surface barrier to become emitting electrons. It is an effective measure to reduce the surface barrier by bringing water on the electrode surface. After the metal surface is covered with water, the original "metal air" interface is divided into "metal water" interface and "water air" interface. The potential barrier of the latter two interfaces is much lower than that of the former interface. In this way, after the metal surface is filled with water, the original high barrier will be divided into two low barriers, which will greatly weaken the blocking effect of the surface barrier on free electrons and make electrons easy to launch. In addition, Electrostatic wet precipitator manufactor Under the action of electric field, various impurity ions in water can easily cross the surface barrier and become emission ions. All of these have changed the electrode discharge effect, enabling corona discharge under low voltage. Secondly, due to the existence of water droplets, the resistance of water is relatively small. When water droplets combine with dust, the specific resistance of dust with high specific electricity decreases, so the working state of wet electrostatic precipitator will be more stable; In addition, since the wet electrostatic precipitator is washed by water flow and has no rapping device, it will not produce secondary dust.
