The ash-laden gas of kind is identical, flow velocity 1m3/ s, difference of the electric precipitator compared with the electric precipitator in embodiment one is only
It is to be not provided with choked flow collecting plate and porous collecting plate, contains via PM2.5 in the electric precipitator treated ash-laden gas
It measures as 5.7mg/m3。
Embodiment two
Electrostatic precipitation processes are done to ash-laden gas using electric precipitator, wherein, pending ash-laden gas and embodiment one
The ash-laden gas of kind is identical, flow velocity 1m3/ s, the electric precipitator be electric precipitator provided by the invention, the electric precipitator
In be provided with choked flow collecting plate and porous collecting plate, through-hole is offered on anode wherein, in through-holes setting protrusion, at this
Attached dirt net is also set up in electric precipitator；Content via PM2.5 in the electric precipitator treated ash-laden gas is 1.8mg/m3。
By above-mentioned experimental example and comparative example it is found that by opening up through-hole on anode plate and setting choked flow collecting plate and more
Hole collecting plate can effectively improve dust collection capacity, reduce the content of PM2.5 in tail gas, further set in the deduster attached
Dirt net sets protrusion also to be able to improve dust collection capacity into a more step, further reduces the content of PM2.5 in tail gas in through-holes.
