Firepower is depended on, thermal power plant can generate a large amount of flue gas while providing and facilitating for us, and flue gas is before being drained into atmosphere
Control techniques should be taken to handle, flue gas emission is made to reach standard requirements, our countries constantly propose to improve the processing of flue gas thus
Technology.A large amount of water mist can be generated while plant emissions flue gas, and water resource is extremely important for thermal power plant, a large amount of mists
There are also very big rooms for improvement for the processing of gas and recovering effect.At present fog processing technique mainly have centrifugation bundled tube demister,
Traditional chevron mist eliminator and vertical pipe type electrostatic precipitator, the dust-laden that the trapping of fog is distributed primarily directed to equipment open-mouth
The control and collection of droplet air-flow.By the trapping to dust-laden droplet, the discharge amount of reduction fog as far as possible is good to guarantee
Production, living environment.
Flue gas before being discharged into atmosphere can pass through 2~3 procedures purified treatment measure, including desulfurization process,
Oxysulfide, nitre oxide in flue gas is carried out purified treatment and collects diameter to be greater than by out of stock processing, vortex-flow and defrosting processing
Droplet equal to 50 microns, but for diameter be 10 microns, temperature 100 degrees centigrades droplet trap effect
Fruit is unobvious, and such droplet can condense to form a large amount of macroscopic water mists, i.e. people while being discharged into atmosphere to the cold
" white cigarette " seen.To handle and collecting " white cigarette ", this paper presents a kind of electrostatic demisting captation based on net like,
That is electrostatic precipitator.
The working principle of electrostatic precipitator: by electrostatic control means and high direct voltage generating device, alternating current is become
DC high-voltage is sent into demister, forms high voltage electric field between corona wire (cathode) and droplet trapping pole plate (anode),
Under high voltage electric field effect, corona layer is generated around corona wire, avalanche type ionization occurs for the air in corona layer, to generate big
The anion of amount and a small amount of cation, this process is corona discharge；Enter the spray dust particle in electric demister with flue gas
It collides with these positive and negative ions and charged, the spray dust particle after these are charged under the action of electric field force, is oriented to anode
Movement discharges the charge of its band after reaching anode, and spray dust particle just collected by anode, forms moisture film, certainly by gravity
Lower part catch basin or cooling tower are flowed upwardly to, to separate with flue gas.And flue gas and electric field side when the processing of conventional electrostatic demister
To vertical, flue gas cannot be effectively collected, it is contemplated that effective recycling to flue gas, and visual pollution " white cigarette " is eliminated, it must
A kind of efficient electrostatic demister must be used.
