A kind of cathode line for wet cottrell
Technical field
The present invention relates to environmental technology field, is a kind of cathode line for wet cottrell specifically.
Background technology
Cathode line is one of core parts of wet cottrell, and the version of cathode line directly has influence on dedusting, the demist efficiency of wet cottrell.At present the cathode line of wet cottrell mostly is astroid, jaggies, common prickle wire etc., and current density is low, has corona dead band, dedusting, except fog effect undesirable.
Summary of the invention
The object of the invention is the problem existing for prior art, provide a kind of new and effective, simple in structure, be easy to manufacture and install the cathode line for wet cottrell, the Rigidity and strength of this cathode line is high, be difficult for rocking, use the wet cottrell of this cathode line to have that discharge inception voltage is low, electric-field intensity is high, the more uniform feature of Electric Field Distribution, solve well the problem that original wet cottrell exists corona dead band, further improved dedusting, the demist efficiency of wet cottrell.
The object of the invention is to solve by the following technical programs:
A kind of cathode line for wet cottrell, comprise cathode rod, it is characterized in that: described cathode rod is provided with prickle ring, the discharge tip of this prickle ring is ring-type or the polygonized structure of pointed shape, is respectively equipped with brace so that cathode line is fixed on cathode frame by brace at the two ends of cathode rod.
Between described prickle ring, be provided with certain spacing.
Described cathode rod is rigid pipe or rigid rod.
Described cathode rod, prickle ring and brace adopt corrosion resistant metal material to make.
The present invention has the following advantages compared to existing technology:
The ring-like cathode line of prickle of the present invention simple in structure, be easy to manufacture and install, the cathode rod in cathode line, prickle ring, brace are all made up of corrosion resistant metal material, conduct electricity very well, long service life; The discharge tip of prickle ring is ring-type or the polygonized structure of pointed shape, make all directions of prickle ring all there is discharging function, the synthetic entirety of cathode rod and prickle loops, have certain spacing, and point of discharge quantity can arrange by demand between each prickle ring.
Cathode line Rigidity and strength of the present invention is high, be difficult for rocking, use the wet cottrell of this cathode line to have that discharge inception voltage is low, electric-field intensity is high, the more uniform feature of Electric Field Distribution, solve well the problem that original wet cottrell exists corona dead band, further improved dedusting, the demist efficiency of wet cottrell.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present invention.
Wherein: 1-cathode rod; 2-prickle ring; 3-spacing; 4-brace.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment, the present invention is further illustrated.
As shown in Figure 1: a kind of cathode line for wet cottrell, comprise cathode rod 1, this cathode rod 1 is for rigid pipe or rigid rod are to guarantee the Rigidity and strength of cathode line, on cathode rod 1, be provided with prickle ring 2, the discharge tip of this prickle ring 2 is ring-type or the polygonized structure of pointed shape, make all directions of prickle ring 2 all have discharging function, cathode rod 1 is combined into entirety with prickle ring 2, between each prickle ring 2, has certain spacing 3; Be respectively equipped with brace 4 at the two ends of cathode rod 1 so that cathode line is fixed on cathode frame by brace 4, and cathode rod 1, prickle ring 2 and brace 4 all adopt corrosion resistant metal material to make.
The ring-like cathode line of prickle of the present invention simple in structure, be easy to manufacture and install, cathode rod 1, prickle ring 2 and brace 4 in cathode line are all made up of corrosion resistant metal material, conduct electricity very well, long service life; The discharge tip of prickle ring 2 is ring-type or the polygonized structure of pointed shape, make all directions of prickle ring 2 all there is discharging function, cathode rod 1 is combined into entirety with prickle ring 2, have certain spacing 3, and point of discharge quantity can arrange by demand between each prickle ring 2; Cathode line Rigidity and strength of the present invention is high, be difficult for rocking, use the wet cottrell of this cathode line to have that discharge inception voltage is low, electric-field intensity is high, the more uniform feature of Electric Field Distribution, solve well the problem that original wet cottrell exists corona dead band, further improved dedusting, the demist efficiency of wet cottrell.
Above embodiment only, for explanation technological thought of the present invention, can not limit protection scope of the present invention with this, every technological thought proposing according to the present invention, and any change of doing on technical scheme basis, within all falling into protection domain of the present invention; The technology that the present invention does not relate to all can be realized by prior art.
