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 turns into because smoke discharge amount is considerable
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
Flue dust minimum discharge transformation is carried out in pole, ensures 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 core component of the cathode line as wet electrical dust precipitator, its purifying property is not only influenceed, 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 bad.
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, easily causes the excessive influence economy of power consumption, while annular tip and circle
The fixation of shape pipe needs pad, the inadequate science of manufacturing process, lacks necessary support between tip and tip, reliability is to be checked
Test.
The content of the invention
To solve the above problems, the invention discloses a kind of wet electrical dust precipitator novel cathode line, discharge effect is good, system
Make technique is simple, intensity is good, reliability is high, service life length.
To reach above-mentioned purpose, technical scheme is as follows：
A kind of wet electrical dust precipitator novel cathode line, it is characterised in that：Including cathode rod, annular tip, fixing hole, institute
It is hollow circular-tube pattern to state cathode rod, and some zigzag annular tips are welded on the outer wall of cathode rod under upper successively,
There is fixing hole at cathode rod both ends respectively.
As a modification of the present invention, described annular tip is directly welded on cathode rod, and manufacture craft is simple, is subtracted
Few cost.
As a modification of the present invention, certain angle between described annular tip and cathode rod be present, angle be to
It is lower 5-8 °, be advantageous to flushing water and preferably slide, preferably form moisture film on anode canister surface, avoid remaining, influence to discharge.
As a modification of the present invention, described annular tip is spherical, and discharge tip is ensureing its discharge performance
On the basis of, substantially reduce energy consumption.
As a modification of the present invention, the spacing between two neighboring annular tip is 50-80mm.
As a modification of the present invention, to guarantee directed entirely to each face of anode canister, electricity existing for solution
Current density is low and corona blocking problem, each annular tip of the present invention are evenly arranged with six tips.
Be arc as a modification of the present invention, between each tip of annular tip, arc tips apart from cathode rod away from
From for 3-5mm, ensure overall rigidity and intensity requirement.
The beneficial effects of the invention are as follows：
A kind of wet electrical dust precipitator cathode line of the present invention, electric-field intensity is high, Electric Field Distribution is uniform；Annular tip
Discharge end designs globulate, can reduce energy consumption, accomplishes that discharge performance is good, discharge inception voltage is low while saving manufacturing cost, very
The good dedusting, the demisting efficiency that solve the problems, such as corona blocking, improve wet electrical dust precipitator；Annular tip is protected with cathode rod
Downward certain angle is held, is advantageous to the formation of moisture film, avoids flushing water remaining influence from discharging.Simultaneously prior art present in just
Property inadequate, fragile problem, segmental arc be present between each tip, there is one between segmental arc and cathode rod in annular tip of the present invention
Determine thickness, disclosure satisfy that to its rigidity and intensity requirement.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention；
Fig. 2 is cathode line part annular cutting-edge structure figure.
Reference numerals list：
