Radial wet electrostatic precipitator The technical features of are as follows:

1) The part in contact with flue gas is made of 2205 duplex stainless steel, which is characterized by high strength, high temperature resistance and corrosion resistance (especially stress corrosion of chloride ion and sulfide), and its service life can reach 30 years.

2) The through-hole ratio of the new positive plate reaches more than 98%, and its almost transparent structure greatly reduces the radial flow Wet dedusting The running resistance of the device. In addition, compared with the ordinary positive plate, the new positive plate has the largest dust collection area under the same volume, which is 20 times of the ordinary positive plate.

3) The anode system is designed with rotating electrode. The bottom of the rotating electrode is provided with an independent cleaning chamber. The high-pressure nozzle is used for washing the outer plate in the rotating electrode, and the sewage after cleaning is sent to the desulfurization tower for water supply through the drainage pump and sewage pipeline. In the project operation, the pressure difference monitoring is used to realize the online spraying and anhydrous circulation system, and the water consumption and power consumption are small.

(2) Runoff type Wet electrostatic precipitator The problems of the controller are as follows:

1) Since all parts contacting with smoke are 2205 duplex stainless steel, the initial cost is relatively high.

2) The anode system is composed of multiple components, and the installation process is complex.

The test results show that the dust removal rate (including gypsum) is ≥ 86%; SO3 removal rate: ≥ 70%; Droplet content: less than 20mg/m3.
