Description
Technical field
The invention belongs to electric cleaner technical field, and in particular to a kind of wet electrical dust precipitator novel cathode line.
Background technology
As the public gives more sustained attention to haze weather, coal electricity industry is considerable due to smoke discharge amount, turns into
The emphasis of public attention.The current environmental protection policy for Emission in Coal-fired Power Plant is constantly becoming tight with standard, coal-burning power plant's product
Carry out flue dust minimum discharge transformation in pole, it is ensured that outlet dust concentration<10mg/m3。
Wet electrical dust precipitator starts to be promoted and answered as terminal purifying equipment in coal-burning power plant's minimum discharge transformation
With, and cathode line not only influences its purifying property as the core component of wet electrical dust precipitator, also contributes to wet electrical dust precipitator
Service life, use cost etc..Wet electrical dust precipitator mainly has fish-bone needle-like, sawtooth pattern etc. using more cathode form,
Wherein fish-bone needle-like discharge effect is good but manufacturing process is complex, is easily damaged during installation and operation, reliability
Difference, sawtooth pattern is hardly damaged but overall discharge effect is not good.
The U of patent CN 204429495 give a kind of solution for taking into account discharge performance and reliability, using a kind of ring
The polar curve pattern of shape, but polar curve point discharge is too strong, the excessive influence economy of power consumption is easily caused, while annular tip and circle
The fixation of shape pipe needs pad, and manufacturing process inadequate science lacks necessary support, reliability is to be checked between tip and tip
Test.
The content of the invention
