Xiangyang Wet electrostatic precipitator manufactor What is the operation content of wet electrostatic precipitator. The dust vapor of the wet electrostatic precipitator enters the middle and lower shells through the air inlet, and the dust vapor enters the upper shell according to the precipitator. In the whole process, dust and gas are separated due to various practical functions of the dust bag. The dust removal bag expands greatly under the instantaneous reverse direction effect of the cyclone, so that the dust accumulated on the surface of the dust removal bag decreases, and the filter bag of the dust remover is modified. According to the whole cleaning process and time addition of the dedusting bag, try to stack a large amount of smoke and dust on the filter bag of the electrostatic induction precipitator. According to the size of the dedusting bag, the amount of steam gradually decreases, and the friction resistance of the dedusting bag increases. The smoke and dust are absorbed by the dust removal bag, and the vapor enters the upper shell through the filter screen pipe and is discharged from the vent. customized Wet electrostatic precipitator In order to control the friction resistance within the limit range, a dedusting pulse controller is required to output steam. Open the pressure regulating valve in sequence, open the pulse solenoid valve of the wet electrostatic precipitator, and the pulse solenoid valve will instantly compress the air in the airbag. Dust falls into the silo and is discharged from the shell through the discharge valve.

The wet electrostatic precipitator has been recognized by users due to many advantages in the process of application. It can remove dust and purify waste gas. It is an environmental protection equipment that can be used in a wide range of situations. What steps can we take when using this environmental protection equipment? today Wet electrostatic precipitator manufactor Let's take a detailed look. 1. First, close the power switch of the wet electrostatic precipitator. When the power indicator is on, the local remote switch will be switched to the local position; 2. Press the fan start button, and then observe whether the fan of the wet electrostatic precipitator rotates correctly. After the fan rotates normally, normal dedusting operation can be started; 3、 customized Wet electrostatic precipitator After a period of time, if you need to clear and discharge the ash, you can press the ash cleaning button on the wet electrostatic precipitator; 4. Turn over the pulse valve to clear the ash, and the screw machine and ash discharge valve will also work together. The above is the whole content of the application process of the wet electrostatic precipitator. What we need to remind us here is that the equipment can be started only after the position is adjusted before it is used. During the dust removal process of the equipment, the humidification function can be started to keep the ground wet, so that the wet electrostatic precipitator can have a better application effect.

Main factors affecting the dust removal efficiency of wet electrostatic precipitator. The effect of electrostatic voltage, water volume and dust concentration on wet electrostatic precipitation efficiency is positive, that is, the dust removal efficiency increases with the increase of voltage, water volume and dust concentration. Among them, voltage has the most significant effect on dust removal efficiency, followed by water volume, and dust concentration has the least effect. The combination of static electricity and water mist can significantly improve the dust removal efficiency. The role of water in wet electrostatic precipitation. The water in wet electrostatic precipitator mainly exists as atomized water droplets. According to domestic research, water mist has a series of effects on the improvement of dust removal efficiency of wet electrostatic precipitator, customized Wet electrostatic precipitator Main mechanism: the water mist can keep the discharge electrode clean and keep the corona vigorous; The mist particles strike the dust collecting electrode to form a thin and uniform water film, Xiangyang Wet electrostatic precipitator It can prevent the "secondary flying" of low specific resistance dust from tempering high specific resistance dust and prevent the occurrence of "reverse corona"; For the dust with strong viscosity, the electrode can be prevented from sticking; It is also suitable for collecting those flammable and explosive dust. The water mist is sprayed directly to the discharge electrode and corona area, and the discharge electrode also acts as an atomizer. The same power supply can realize corona discharge, water atomization, water mist and dust particle charging, realizing the organic combination of static electricity and water mist. The water mist is directly sprayed to the discharge electrode, which has a high charge. The collision interception, adsorption and coagulation of water mist with high charge mass ratio in the electric field can greatly improve the dust removal efficiency. The water mist strikes the dust collecting electrode to form water flow down, so that the dust collecting electrode is always kept clean, eliminating the vibrating device, and avoiding a series of problems caused by vibrating dust removal in dry dust removal. In the method of spraying water mist to the discharge electrode and corona area to further atomize the water mist, the static electricity does not directly contact the spray device, so there is almost no insulation problem. This method is completely different from the dedusting technology of "corona discharge atomizes water". The latter is almost impossible to insulate due to the direct contact between water and electricity, and it is actually difficult to achieve industrial application. The barbed electrode can produce a strong electrostatic field, and has a good corona discharge capacity. The electrostatic and water mist work together, and has a high dust removal efficiency
