because Wet electrostatic precipitator It operates under wet flue gas conditions, and the corrosion of its shell and internal metal components has become a difficult problem in its application (if you do not understand the harsh working conditions, you can refer to the selection and maintenance of wet chimney materials). At present, the wet motor shell is lined with glass flakes to prevent corrosion.

"The positive plate is usually made of 316L, which does not have good anti-corrosion performance. It mainly depends on evenly coating a layer of water film on the plate to prevent the plate from being corroded by smoke. Once the water film is damaged, the positive plate will quickly corrode. This requires high-level design, manufacturing, installation and good on-site management."

Tubular Wet electrostatic precipitator Apparatus and plate wet type Electrostatic precipitator The main difference lies in the choice of anode materials.

The precipitator of plate wet electrostatic precipitator is generally made of 316L stainless steel, with poor corrosion resistance. It must be cleaned continuously with neutral or slightly alkaline spray water to form a uniform and continuous protective film.

The general form of dust remover plate, but the structural stiffness plates on both sides are usually set in the arc or C shape, so it is easy to form a water film washing plate, but the arc or water film is difficult to form, so there is hidden corrosion.

Continuous washing has the advantage of timely ash removal, but the water consumption is too large, and washing water must be added with a large amount of lye for neutralization and post circulation.

In addition, the formation of continuous water film is related to the selection of nozzles. In general, the atomization effect of nozzles is very good, the number of nozzles is large, the amount of operation and maintenance is large, and the requirements for water quality are high. The recycled rinse water must be equipped with a high-precision coarse particle filter.

Therefore, for the plate wet electrostatic precipitator, once the nozzle is blocked or the plate water film is discontinuous, the precipitator is prone to corrosion and scaling, which greatly affects the service life of the plate electrostatic precipitator.

The dust collector of tubular wet electrostatic precipitator is made of anti-corrosion conductive glass fiber reinforced plastic (FRP). The material is composed of polymer material as binder, glass fiber and its products as reinforcement, and high-strength carbon fiber as conductive material. Inner Mongolia wet electrostatic precipitator is resistant to various organic solvents and acid-base corrosion, which matches the conductivity and flame retardancy of the materials. It has the characteristics of light weight, good corrosion resistance, good conductivity and long service life.

This kind of transistor usually adopts regular hexagon and adjacent common wall diode, which has high strength after forming mode. Compared with the metal plate, the glass fiber reinforced plastic pipe has strong corrosion resistance, and the wet electrostatic precipitator is quoted, so it only needs time to wash (1 - 3/d), and the water consumption is very small. There is no need to set up a circulating water treatment system, and there is no need for alkali neutralization. The washing nozzle is very small, and the number of operations and maintenance is very low.
