Abstract
The invention discloses a fishbone needle type cathode line for a wet type electric precipitator. The fishbone needle type cathode line comprises a cathode rod. The cathode rod is sleeved with a plurality of stainless steel rings. Each stainless steel ring is fixedly connected with N fishbone needles. The included angle between every two adjacent fishbone needles is 360 degrees/N, wherein N is a positive integer. The N fishbone needles on the adjacent stainless steel rings are arranged in a staggered manner. The discharge sharp end of each fishbone needle is in a ball shape. The novel fishbone needle type cathode line for the wet type electric precipitator is simple in structure, convenient to install, high in dust removing efficiency and capable of being adjusted in good time according to actual situations. The cathode line has the beneficial effects that the discharge inception voltage is low, the voltage current characteristic is good, and the adaptability to the smoke change is high, and the dust and mist removing efficiency is guaranteed.
Description
Technical field
The present invention relates to environmental technology field, particularly a kind of fish-bone needle-like cathode line for wet electrical dust precipitator.
Background technology
Cathode line is as the core component of wet electrical dust precipitator, and its structural shape directly affects the flue gas deep purifying effect of wet electrical dust precipitator.The cathode line pattern of current wet electrical dust precipitator mainly contains astroid, jaggies, common prickle wire etc., and because coal-fired plant flue gas dust content is higher, be easy to corona blocking occurs, fish-bone needle-like cathode line often selected by electric cleaner.
In wet electrical dust precipitator, the pattern of positive plate is mostly honeycomb fashion, cathode line needs to set up electric field with the positive plate in multiple (>=4) face, and existing fish-bone needlework are at negative electrode body both sides welding two row fish-bone pin, only directly set up electric field for two anode surfaces, there is the problems such as the low and corona blocking of current density, higher requirement is proposed to the discharge performance of fish-bone stylus line.Meanwhile, the performance requirement of different working conditions to wet electrical dust precipitator is different, and as the core component of wet electrical dust precipitator, the requirement of target line is also different, as the density, orientation etc. of fish-bone pin.Current cathode line has designed and produced rear sizing and has been difficult to change, and can only change, cause great waste, so need a kind of cathode line that can adjust according to on-the-spot actual condition in good time after field working conditions condition changes.
Summary of the invention
The technical problem to be solved in the present invention is for current wet electrical dust precipitator cathode line discharge performance shortcoming, easy generation corona blocking, design dumb simultaneously, the deficiency that in good time can not adjust according to on-the-spot actual condition, and provide a kind of better flash-over characteristic that has to be convenient to assembling, convenient, flexible cathode line simultaneously.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of fish-bone needle-like cathode line for wet electrical dust precipitator, comprise cathode rod, described cathode rod is arranged with several stainless steel rings, a stainless steel ring is fixedly connected with N root fish-bone pin, angle angle between adjacent fish-bone pin is 360 °/N, and wherein N is positive integer; N root fish-bone pin layout straggly on adjacent stainless steel ring; The discharge tip of every root fish-bone pin is spherical.
Preferably described fish-bone acupuncture vertical welding is on ring-type body.
On the most advanced and sophisticated basis ensureing its discharge performance of globular discharge, reduce energy consumption.
The internal diameter of several stainless steel rings described equals the external diameter of cathode rod, and the external diameter of several stainless steel rings is all equal.Stainless steel ring is sheathed on cathode rod, and can slide up and down, and rotates, and fish-bone pin density degree can adjust.Simultaneously, one-tenth 120 ° between the fish-bone pin that same stainless steel ring is adjacent, respectively to three directions, the fish-bone pin in adjacent sections can become 180 ° or more low-angle is symmetrical, can completely for each, anode, thoroughly solve the problems such as the low and corona blocking of the current density existed.
Fish-bone pin on adjacent two stainless steel rings can to six and the electric discharge of above direction, the fish-bone needle-discharging direction of upper lower section is not repeated, accomplish that discharge performance is good, discharge inception voltage is low, electric-field intensity is high, the uniform feature of Electric Field Distribution while saving manufacturing cost, well solve the problem of corona blocking, improve the dedusting of wet electrical dust precipitator, demisting efficiency.
The two ends of described cathode rod offer locating hole, are convenient to cathode rod is fixed on cathode frame.
Preferably, described fish-bone pin length is 20mm.
After the present invention adopts said structure, there is following technique effect:
Electric-field intensity of the present invention is high, Electric Field Distribution is even; Fish-bone needle-discharging end is designed to spherical, can reduce energy consumption, accomplishes that discharge performance is good, discharge inception voltage is low, well solve the problem of corona blocking, improve the dedusting of wet electrical dust precipitator, demisting efficiency while saving manufacturing cost.The problem of easily luminous efficiency decline after the long-play simultaneously existed in prior art, realizes secondary by the angle of fish-bone pin on adjustment fish-bone pin density and adjacent stainless steel ring and improves, increase operation rate.
Structure of the present invention is simple, be convenient to install, efficiency of dust collection is high, the wet electrical dust precipitator Novel fish spicule type cathode line that in good time can adjust according to actual conditions, this cathode line has that discharge inception voltage is low, C-V characteristic good, change adaptable feature to flue gas, ensure that dedusting, demisting efficiency.
