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 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, 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, so as to flush the dust captured on the dust collection plate into the ash hopper and then discharge 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.

The wet electrostatic precipitator is mainly used to purify water vapor, odor, acid mist and other harmful substances in the exhaust gas discharged by the factory. As an air pollution control equipment, it has also been widely used. let's Electrostatic wet precipitator company Understand its system composition together. 1. Composition of wet electrostatic precipitator system. According to its working principle, the control system of wet electrostatic precipitator generally includes high pressure system, water treatment system, low pressure heating and hot air purging system, upper computer system, etc. 2. Design of wet electrostatic precipitator system. (1) customized Electrostatic wet precipitator High voltage system and wet electrostatic precipitator charge the dust through corona discharge of high voltage system. The charged dust reaches the dust collecting plate under the effect of electric field force, and then the dust is removed by regular scouring. (2) Hezhou customized Electrostatic wet precipitator Water treatment system. This system deals with the problem of secondary water pollution. It is mainly the water discharged after equipment spraying and flushing, which contains a lot of acid substances and fine particles. Direct discharge will cause secondary pollution. The recycling of water in the equipment consists of two steps: neutralization and acid removal, and separation of suspended solids, so that the sewage can be turned into industrial water suitable for spraying. (3) Heating system. The heating system includes insulator incubator heating, hot air purging heating, and the hot air purging system is composed of fan, butterfly valve and heater. When it starts actively, it starts in the order of fan, butterfly valve and heater. When actively closing, it shall be closed in reverse order. (4) Upper computer system. The selected upper computer system is an industrial control computer, and the network front-end computer is used to enable the system to have extraordinary data acquisition and processing capabilities, so as to meet the requirements of wet electrostatic precipitator for centralized management, decentralized control, energy conservation and emission reduction.

The operating principle of wet electrostatic precipitator is different from other equipment. The dusty gas enters the expanded ash hopper of the wet electrostatic precipitator for pre collection, and is evenly distributed between each filter bag through the guide plate. The dust is retained on the surface of the filter bag. In order to make the equipment resistance not exceed 1200pa, the high-pressure gas will pulse through the electromagnetic pulse valve, so that the compressed air in the air bag will be ejected from the nozzle hole (called primary air) The surrounding air (called secondary air), which is several times of the primary air, is induced through the venturi to enter the filter bag to make the filter bag expand rapidly in an instant, and shake off the dust with the reverse effect of the air flow to reach the purpose of ash removal. The microcomputer automatic control device is used to adjust the ash cleaning cycle and pulse spraying time randomly according to the dust concentration, so that the dust collector can operate within the resistance range. When changing the bag of the wet electrostatic precipitator, open the top bag changing cover and directly pull out the filter bag, which is simple and convenient to protect. Hezhou customized Electrostatic wet precipitator Wet electrostatic precipitators are mostly used in bag type precipitators. Dust removal bags are installed in the gas box. Wet electrostatic precipitators are mostly external filter type. Dust is collected in the ash hopper of wet electrostatic precipitators through the injection of pulse solenoid valves. The wet electrostatic precipitator is installed in a simple structure. This device is planned as an internal filtering structure, which can change the external pressure of the wet electrostatic precipitator to the internal pressure. In this way, the shell of the wet electrostatic precipitator can be structured without external iron plate sealing, which saves costs and does not hinder the use of the wet electrostatic precipitator. The processing of wet electrostatic precipitator is particularly important. In recent years, some Electrostatic wet precipitator company Small manufacturers use small sewing machines as processing equipment, and use low-quality thread as raw materials during processing, which is fake, and the processing level is far behind. The wet electrostatic precipitator will open lines, cracks, and drop the bottom after a short time of operation. Although the size of the cloth bag is slightly smaller, it can also be used, but after absorbing the dust with large specific gravity, the bag will drop after a period of use.

Hezhou customized Electrostatic wet precipitator Fan performance parameters. The performance parameters of fan mainly include flow, pressure, power, efficiency and speed. In addition, the size of noise and vibration is also the main fan design index. Flow, also known as air volume, is expressed by the volume of gas flowing through the fan in unit time; Pressure, also known as wind pressure, refers to the pressure rise value of gas in the fan, including static pressure, dynamic pressure and total pressure; Power refers to the input power of the fan, namely shaft power. The ratio of effective power of fan to shaft power is called efficiency. Electrostatic wet precipitator company The total pressure efficiency of fan can reach 90%. Fans are widely used for ventilation, dust discharge and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings; Ventilation and induced draft of boiler and industrial furnace; Cooling and ventilation in air conditioning equipment and household appliances; Drying and selection of grain; Wind source of wind tunnel and inflation and propulsion of hovercraft. The working principle of the fan is basically the same as that of the turbine compressor, but because the gas flow rate is low and the pressure changes little, it is generally unnecessary to consider the change of gas specific volume, that is, treat the gas as an incompressible fluid
