Description
Technical field
The present invention relates to industry environmental protection technical field, more particularly to one kind ladder can be formed for vertical wet cottrell
Spend the cathode line of field intensity.
Background technology
Vertical wet cottrell is a kind of efficient cleaner, is arranged in after desulphurization plant, can not only be right
Fine particle in coal-fired flue-gas is finely removed, and can trap the heavy metals such as aerosol, Hg, while treatment is various
Pollutant, is the visual plant for realizing coal-fired flue-gas minimum discharge；The principle of gathering dust of wet electrical dust precipitator is put by high-voltage corona
Electricity causes that dust is charged, it is charged after dust reach collecting plate in the presence of electric field force, wet electrical dust precipitator is using punching
Brush liquid rinses electrode, and continuous liquid film is formed on pole plate, dust is removed with the flowing for washing away liquid.
After dust granules enter electric precipitation, big dust particle is easily charged, and carrying capacity is big, and the electric field force being subject to is big, easy
To trapping, and particle dust, carrying capacity is few, is difficult to obtain trapping；Dry electric precipitation is by setting multistage electric field and changing cloudy
The method of polar curve type, strengthens rear portion electric field strength, so as to effectively collect relatively fine particle dust；Wet-esp generally sets single-stage
Electric field, single field intensity, so, fine grained arresting efficiency, it is impossible to play to optimal.
In view of this, it would be highly desirable to optimize negative electrode cable architecture, to solve the above problems.
The content of the invention
Core purpose of the invention is, there is provided a kind of cathode line that gradient strength is capable of achieving in same electric field.
To achieve the above object, the concrete technical scheme of the cathode line of a kind of vertical wet cottrell of the invention
For：
1st, a kind of cathode line of vertical wet cottrell, including on a cathode rod and cathode rod outer wall arrange it is many
Individual discharge body, it is characterised in that：Cathode line is arranged in parallel in flue gas flow direction and with the negative electrode bar part of smoke contacts is in advance the moon
The fore-end of pole bar, on the contrary it is the rear end part of cathode rod, and multiple discharge bodies are along the length of cathode rod radial direction is non-isometric and cloth
The electric discharge body length put in cathode rod fore-end is less than the electric discharge body length for being arranged in cathode rod end section.
2nd, the cathode line of a kind of vertical wet cottrell according to above-mentioned 1, it is characterised in that：Cathode rod front end
Partial length accounts for 4th/to five/2nd of negative electrode pole length.
3rd, the cathode line of a kind of vertical wet cottrell according to above-mentioned 1, it is characterised in that：Discharge body can be adopted
With the discharge body in fish-bone cathode line, the discharge body in RS cathode lines, the electric discharge that can also use in multiple tooth cathode line can be also used
Body.
4th, the cathode line of a kind of vertical wet cottrell according to above-mentioned 1, it is characterised in that：Cathode rod and put
Electric body is made of metallic conductor.
5th, the cathode line of a kind of vertical wet cottrell according to above-mentioned 1, it is characterised in that：Discharge body is most
The difference of the minimum length of long length and discharge body is more than or equal to 3mm and less than or equal to 30mm.
6th, the cathode line of a kind of vertical wet cottrell according to above-mentioned 1, it is characterised in that：Same cathode rod
Multiple discharge bodies are distributed with for radial section and the angle of multiple discharge body formation is 90 degree or 72 degree or 60 degree.
Beneficial effect
The technical program, using the negative electrode line style of innovation, coordinates in single electric field with deduster dust collection plate or dust-collecting pipe
High voltage electric field is formed, due to the length Length discrepancy of discharge body, therefore, the high voltage electric field field intensity cooperatively formed with the anode that gathers dust is not
Together, and because the length of discharge body according to increasing successively from the order of A-P, so the high voltage electric field field intensity for being formed
It is enhanced successively according to the order from A-P, material is thus formed gradient strength, front end low field intensity, trapping bulky grain is highly concentrated
Degree pollutant, rear end high field intensity traps fine grained low concentration pollutant, simulates the mode of operation of many electric-field dust collectors, improves
Wet electrical dust precipitator gross efficiency, reduces the efficiency requirements for upstream dry electric precipitation device, improves pollutant control effect
Really.
Brief description of the drawings
Accompanying drawing 1 is schematic diagram of the invention
Accompanying drawing 2 is A-A faces schematic diagram in Fig. 1
Wherein 1, gather dust anode 2, cathode line 3, cathode rod 4, discharge body 5, it is upper hanging 6, lower hanging.
Specific embodiment
A kind of cathode line of vertical wet cottrell of the present invention is shown in Fig. 1-Fig. 2.With reference to Fig. 1, Fig. 2, the present invention one
Plant the cathode line of vertical wet cottrell（2）Including a cathode rod（3）With the multiple electric discharges arranged on cathode rod outer wall
Body（4）, cathode line（2）With flue gas flow direction parallel arrangement and cathode line（2）With the anode that gathers dust（1）It is parallel；Gather dust anode（1）Shape
Shape is preferably six rhombuses or circle, and any shape well known in the art can be also used certainly；Multiple discharge bodies（4）And cathode rod
（3）Connected using any known method in this area, it is preferred using welding manner connection；Multiple discharge bodies（4）Along cathode rod
（3）The length of radial direction is non-isometric and is arranged in cathode rod（3）The discharge body of fore-end（4）Length is less than and is arranged in cathode rod
（3）The discharge body of end section（4）Length, cathode rod（3）Fore-end in advance and smoke contacts, otherwise be cathode rod（3）
Rear end part, certainly, also dependent on the flue gas successively order that contacts successively by cathode rod（3）It is divided into fore-end, middle-end
Part and rear end part or more parts；Same cathode rod（3）Radial section is distributed with multiple discharge bodies（4）And multiple electric discharges
Body（4）The angle of formation is preferably 60 degree, and 90 degree of angles or 72 degree of angles can be also used certainly；Discharge body（4）Using ability
Discharge body structure known to domain, for example, the discharge body in fish-bone cathode line, in the discharge body, multiple tooth cathode line in RS cathode lines
Discharge body；Cathode line（2）Using method well known in the art and upper hanging（5）With lower hanging（6）It is connected to a fixed, upper hanging
