Specific embodiment
The utility model is described in further details below with reference to Figure of description and specific embodiment.
As shown in Fig. 1 ~ Fig. 4: a kind of electrostatic precipitator, including along the corona zone that inlet air flow path is set gradually 1, solidifying
And area 2 and integrated area 3.Corona zone 1, coalescence area 2 and integrated area 3 are set in cabinet 4, and the top of cabinet 4 is equipped with earth plate 5,
The ventilation hole 51 of multiple arrangements is offered on earth plate 5, so that dusty gas can enter in cabinet 4 from ventilation hole 51.
Corona zone 1 uses tungsten wire or needle point, it is preferred to use needle point 11, needle point 11 preferably use rectangular distribution.This implementation
The needle point of example has following two arrangement: one is the direction that the tip of needle point is directed toward to coalescence area, i.e. tip is arranged downward,
Another kind is that the tip of needle point is arranged upward.Needle point can be fixed on suitably by the present embodiment according to the design structure of cloth in cabinet
Position.Such as: when the tip of needle point is arranged downward, needle point can be fixed on earth plate, and be vertically arranged with air intake plate；
When the tip of needle point is arranged upward, needle point 11 can be fixed on to the top of spaced positive plate 12 in corona zone.This reality
