By high-voltage corona discharge, so that droplet and dust charged near corona zone, under the collective effect of electric field force and electric wind, mist
Drop, dust, which can efficiently separate arrival with flue gas and gather dust, pole surface and then to be captured, then makes to be rinsed with water by automatic spraying device
Mode the dust for pole surface of gathering dust is washed down, by gravity discharge wet electrical dust precipitator outside.In the flue gas of anode tube
After most of flue dust collects removing by anode tube, to realize that ultra-clean is discharged.
Anode tube as dust collector pole is generally made by glass reinforced plastic, PP plastics or metal material, and shape is round tube or bee
Nest tubulose.Cathode line is then made by metal, and shape is generally the tubulose, band-like or rodlike for having several needles thorn.Each sun
Piece cathode line of center arrangement of pole pipe forms the one the smallest unit that gathers dust.One wet electrical dust precipitator by multiple anode tubes simultaneously
Column composition.The anode module of an entirety is formed between anode tube by bonding or welding, and each independent cathode line is then led to
It crosses cathode frame connection and forms a whole set of cathod system.
Cathode line is as discharge electrode, it is desirable that arragement construction is reliable and stable, it is necessary to assure heteropolar away from i.e. cathode line and anode tube
The distance between it is constant, just can guarantee wet electrical dust precipitator working voltage and electric current stablize.Existing cathode line is flexible flexible cord,
Multiselect lead-antimony alloy, flexible flexible cord are easy to shake in flue gas to cause voltage and current extremely unstable, and yin is even caused when serious
Anode overlap to form short circuit, it is therefore necessary to every cathode line be strained and fixed by upper and lower ends, be just avoided that cathode line is shaken
It is dynamic.
The cathode line of existing wet electrical dust precipitator is usually fixed by upper cathodic frame and lower cathodic frame, to protect
The stabilization of cathode line is demonstrate,proved, the metal parts such as the cathode frame entirely connecting with cathode line, cathode sunpender are referred to as cathod system, yin
Electrode systems are the equipment with high-voltage electricity, generally vacant state.Top cathode frame is connect with cathode sunpender, and cathode sunpender will be whole
