3. using anticorrosion material, electrode is not directly contacted with exhaust gas, fundamentally solves equipment etching problem.
4. only needing electricity consumption, operation is extremely simple, without sending full-time staff to guard, is not take up labour cost substantially.
5. equipment starting, stopping are very rapid, with with opening, do not influenced by temperature.
6. vapour lock is small, technical maturity.
The working principle of plasma purification Industry Waste:
In discharge process, electronics obtains energy from electric field, converts energy to by colliding the interior energy of contaminant molecule
Or kinetic energy, these molecules for obtaining energy, which are excited or occur to ionize, forms active group, while oxygen and moisture in air
It also can produce a large amount of hydrogen in statu nascendi, ozone and hydroxyl oxygen isoreactivity group, these active groups under the action of high energy electron
Physics, the chemical reaction of a series of complex are mutually just caused after collision.It can be seen that from the active group of plasma composition
High chemically active particle, such as electronics, ion, free radical and excited state molecule are rich in inside plasma.In exhaust gas
Polluter and these active groups with higher-energy react, and are eventually converted into CO2And H2The substances such as O, to reach
Purify the purpose of exhaust gas.
In addition, high energy electron also can become anion by the stronger materials capture of the electron affinities such as halogen and oxygen.This
Class anion has good chemical activity, plays an important role in chemical reaction.
