The corresponding anode tube bank for being arranged identical quantity, the axle centered on pole bar of discharging；Electric discharge pole bar and anode tube bank connect high pressure respectively
The negative pole and positive pole of power supply.
Further improvement as above-mentioned technical proposal：
The electric discharge pole bar can be radial distribution or rectangular array arrangement.
The anode tube bank is circular, square or honeycombed stainless steel tube.
The negative electrode fixed frame uses stainless steel frame.
The electric discharge pole bar is stainless steel optical wand.
In electric discharge pole bar and the both ends that negative electrode fixed frame is fixed, seal is set.
The seal uses ceramic material.
The beneficial effects of the utility model are as follows：The utility model is arranged on the dust-removal and desulfurizing in hazardous waste burn system
The lower section of exhanst gas outlet in device, cathod system use stainless steel discharge pole bar, and discharge performance is good, discharge inception voltage is low, breakdown potential
Press strong height, corona current, high mechanical strength, be not easy dust stratification.Electrode systems of catchmenting use bundled tube electrode, can be circular, sides
Shape or honeycombed, space electric field are evenly distributed, no edge flashing, suitable for large-scale demister.Electric discharge pole bar can be radially
Distribution or rectangular array arrangement, arrangement is reasonable, can not only save space, and demisting is more when the flue gas is passed through high voltage electric field
Fully, compact-sized, defogging effect is good.The utility model is in light weight, small volume, take steel it is few, reduce construction investment, economy
It is practical, while have the advantages that corrosion resistance is strong, catchment area is big concurrently.
