working principles:
The white smoke and yellow smoke produced by oxidation electroplating plants and chemical enterprises are mainly caused by the waste gas emission that has not been treated or the treatment is not up to standard when using strong acids such as nitric acid. The main components are: NO2, SO2, NO, etc. The working principle for FSNOAH’s HHV series acid mist purification device: the instantaneous high-intensity electric field corona generated by high-frequency narrow pulse power supply can excite the discharge electrode (cathode) to release high-energy electrons instantly, and the high-energy electrons can bombard acid mist gas molecules under normal pressure in a limited space , forming high-speed positive and negative ions. High-energy electrons and high-speed positive and negative ions hit some atoms and molecular clusters to the receiving electrode (anode), so that the acid mist gas gets energy and is excited, and the ionization is converted into other substances and removed. At the same time, during the impact process, high-energy electrons will break the molecular bonds of sulfate and nitrate to achieve the effect of desulfurization and denitrification, thereby removing the white smoke and yellow smoke generated.

Working process:
Product feature:
a. High dust and fog removal efficiency. The efficiency can reach more than 95%. b. Small smoke resistance. The airflow is evenly distributed and the cathode line remains stable for optimum results. c. Light weight, high strength, stable shape and dimension, and long service life of equipment. d. Compact structure. The honeycomb structure makes the inner and outer surfaces of each pole tube become the collector surface. There is no dead zone between the pole tubes. Therefore, it has a small volume and occupies a small area for dealing with flue gas of the same scale.
Main feature:
1. Patented product is specially used for acid mist purification processes such as nitric acid, sulfuric acid, hydrofluoric acid, phosphoric acid, and hydrochloric acid. 2. The purification rate can reach 95%. 3. Save 50~80% materials for alkali neutralization. 4. This process has no consumables and no secondary pollutants. 5. Less investment, low operating cost and simple maintenance.
6.Pulse frequency 80kHz, pulse width 0-10μs. 7.Voltage ripple <1%, μs level arc spark response speed. 8.Breakthrough of corona sealing, no back corona phenomenon. 9.50% power saving than power frequency power supply, 20% power saving than ordinary high frequency power supply. 10.Continuous working with water spray: clean the electrostatic field without stopping the power supply. 11.Exhaust gas purification by plasma reduction method.
