The use of wet electrostatic precipitators is becoming more and more common. How much do you know about the equipment? Today, I'm going to popularize knowledge for you and talk about the advantages and disadvantages of wet electrostatic precipitator. Let's learn together. Advantages of electrostatic precipitator High purification efficiency, capable of spreading fine particles of more than 0.01 microns. In the design, different operating parameters can be used to meet the required purification efficiency. ⑵ The resistance loss is small, generally below 20 mm water column. Compared with cyclone dust collector, the total power consumption is small even considering the power consumption of power supply unit and rapping mechanism. ⑶ Shaoguan Wet dust collector The allowable operating temperature is high. For example, the allowable operating temperature of SHWB type circuit dust collector is 250 ℃. Other types can reach 350~400 ℃ or higher. ⑷ Large gas processing range. ⑸ major Wet dust collector Automatic operation control can be fully realized. Disadvantages of electrostatic precipitator The equipment is relatively complex, requiring a high level of equipment allocation, installation and maintenance management. ⑵ There are certain requirements for the specific resistance of dust, so there is a certain selectivity for dust, which can not make all dust obtain high purification efficiency. ⑶ It is greatly affected by the operating conditions such as air temperature and temperature. If the same kind of dust is operated at different temperatures and humidities, the results will be different. Some dust can work well at a certain temperature and humidities, but the ESP can hardly be used at another temperature and humidities due to the change of dust resistance. ⑷ Wet dust collector company The primary investment is large, and the horizontal electrostatic precipitator covers a large area. ⑸ At present, the practical effect in some enterprises can not meet the design requirements.

Among all kinds of mechanical and electrical equipment in all walks of life in China, the motors matched with fans account for about 60% of the installed capacity of national motors, and the power consumption accounts for about one-third of the total power generation in China. In particular, Wet dust collector company Most fans have the phenomenon of pulling a cart from a horse during use. In addition, due to changes in production and technology, it is necessary to frequently adjust the gas flow, pressure, temperature, etc; Many units still adopt the backward way of adjusting the opening degree of the wind shield or valve to adjust the gas flow, pressure, temperature, etc. In fact, this is to meet the requirements of process and working conditions for gas flow regulation by artificially increasing resistance at the cost of wasting electric energy and money. This backward regulation mode not only wastes valuable energy, but also has poor regulation accuracy, which is difficult to meet the requirements of modern industrial production and services, and has serious negative effects. With the continuous improvement and development of frequency conversion technology in recent ten years. The performance of variable frequency speed regulation is becoming increasingly perfect, major Wet dust collector It has been widely used in AC speed regulation in different fields. It has brought considerable economic benefits to enterprises and promoted the automation process of industrial production.

Forecast from domestic market capacity. Shaoguan Wet dust collector company Fans vary greatly according to different pressure and flow requirements. Therefore, the fan demand should be differentiated according to its type and size, and predicted according to the demand of different industries. According to incomplete statistics, the annual average growth rate of national fan output was 13.8% from 1980 to 1996. major Wet dust collector It is estimated that the total output of wind turbines in China will be 2.6 million to 2.9 million in 2005 and 3.1 million to 3.25 million in 2010. According to the statistics of fan industry over the years, it is predicted that the output of centrifugal compressors will be 1.6 million to 1.8 million in 2005 and 2 million to 2.1 million in 2010; The output of axial compressor is 260000 in 2005, and is expected to reach 360000 in 2010; The market share of turbine compressor and blower will reach about 70% in 2005

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. Wet dust collector company 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, major Wet dust collector 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. High temperature, flammable, explosive and harmful gases; Normal operation and high purification efficiency; Dust and gas that can be used for gathering fog and dust; Exhaust volume balance; Simple structure. Low investment, convenient operation and maintenance.
