Plasma wet scrubber(CREOTM)
CREOTM
Principles and Features
- Exhaust gas flowing into Thermal Plasma Scrubber using N2Using DC power supply
- The flame formed by the arching between the cathode and the anode in two stages Decompose chemical bonds (Plasma about 2,500 ℃ ~ 5,000 ℃)
- In the second and third reaction chambers (yellow and blue)
Maintain high temperature to increase processing efficiency (Adopt condensing method)-> Maintain about 1,000 ℃ when passing through secondary reaction chamber - When the exhaust gas communicates with the 3rd reaction zone (blue), the external cooling chamber
The hot exhaust gas is cooled by passing through. -> Maintain about 600 ℃ when passing through 3rd reaction chamber - Treatment of residual exhaust gas by supplying city water for water-soluble gas and cooling in the primary wet spray part.
- NOx bonds occur above about 800 ° C. May occur when encountering H2O When NO2 Plasma encounters water, NOx generation is suppressed to about 600 ℃
- Plasma treated exhaust gas is directly in contact with H2O
This is the cause of NOx occurrence.
