Abstract
The utility model relates to a discharge electrode for an electric dust remover, which is composed of a cathodic plate (1) and discharge thorns (2). Both sides of the cathodic plate (1) are provided with a plurality of discharge thorns (2) perpendicular to the cathodic plate (1). The density of the discharge thorn (2) is 100-400 /m< 2 >, and the length is 5-15 mm. the utility model is adopted to form the plate-thorn plate type dust collection electric field with a dust collection pole plate. Compared with the conventional plate-line type electrical field, the average field intensity in the electric field can be improved by 1 time. Under the condition of keeping the dust collection efficiency, adopting the utility model can reduce the volume of the electric dust remover by more than 50%.
Description
The utility model relates to the device of electrostatic effect from gas or steam, separation diffusing particle, relates in particular to a kind of discharge electrode of electric cleaner.
Electric cleaner is a kind of deduster of efficient, low-resistance, but because floor space is big, and equipment investment is many, the application of its reality has been subjected to considerable restraint.The sinking speed of particle in the electric cleaner electric field except the characteristic of flue gas and dust, depends primarily on electric-field intensity and ion concentration in the electric field.Traditional electric cleaner generally adopts plate---and the line type electrode configuration, the electrode that promptly gathers dust adopts template, the star electrode of discharge electrode employing linear structure, arista electrode etc.As CN902092111 " a kind of electric cleaner cross corona wire ", a kind of wire discharge electrode of decussate texture is disclosed.Plate commonly used---electric-field intensity distribution is very inhomogeneous in the electric field of line type electrode configuration, average field intensity is lower, be about half of average field intensity between the line plate, make that the sinking speed of particle in electric field is lower, in order to reach higher efficiency of dust collection, have to increase the time that air communication is crossed electric field, promptly increase the volume of electric cleaner, make the floor space of electric cleaner and cost improve.
The purpose of this utility model be to provide a kind of can the homogenizing electric field and increase electric-field intensity, reduce the discharge electrode of the thorn template structure of electric cleaner volume and gross investment.
The purpose of this utility model can realize by following measure:
It comprises minus plate (1) and discharge thorn (2), and minus plate (1) is parallel to air-flow to be placed, and its both sides are provided with several discharge thorns (2) perpendicular to minus plate (1), and the density of this discharge thorn (2) is 100-400/m
2, length is 5-15mm; Discharge thorn (2) can be triangle, taper, it also can be cuspidated other shape, discharge thorn (2) can be fixed on the minus plate (1), and its fixing mode is to be through on the minus plate or to be welded on the minus plate, also can directly shut out triangle as the discharge thorn from minus plate.Minus plate (1) can be made with metal plate, also can make with the metal template.
The utility model is compared with present technology and is had the following advantages:
(1) can the homogenizing electric field, strengthen electric-field intensity.The experiment proved that: 2 times of---average field intensity in the thorn template electric field is traditional plate---line formula electric field with the plate of this utility model and dust collecting pole plate composition, average field intensity improves 1 times in the electric field, thereby particle velocity is improved greatly, keeping under the constant situation of efficiency of dust collection, the electric cleaner volume can reduce more than 50%, and the floor space of electric cleaner and gross investment are reduced greatly.
(2) simple in structure, easily manufactured, be easy to install.
(3) adopt thorn plate structure discharge electrode, avoid the broken string problem in the printed line formula electric cleaner.
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is the schematic diagram of the utility model embodiment 1 front view and side view.
Fig. 2 is the schematic diagram of the utility model embodiment 2 front views and side view.
The utility model has changed the method for traditional printed line electrode configuration, has adopted thorn The template discharge electrode. Since on the metallic plate of this thorn template discharge electrode with some Point discharge point, metallic plate play a part to form uniform electric field intensity, and the tip can To form stable corona discharge and space charge. Discharge thorn length is 5 on the minus plate～15mm, its density and distribute can according to different sections in the electric cleaner and want The strength of discharge of asking determines that the number density of general discharge thorn is 100～400/m2, Evenly distribute.
Embodiment:
The thorn template discharge electrode that the utility model provides and two dust collecting pole plate configurations are formed electric field and are experimentized.
1: shown in accompanying drawing one: minus plate (1) is made by metallic plate, and discharge thorn (2) is distributed in minus plate (1) both sides and vertical with this minus plate (1).Discharge thorn (2) can be through on the minus plate (1), also can be welded on the minus plate (1), perhaps puts on and then welds.Discharge thorn (2) can be selected for use and have most advanced and sophisticated wire.
In the experiment, the length of discharge thorn and density are respectively at 5～15mm and 100～400/m
2Change in the scope.
2: shown in accompanying drawing two: minus plate (1) is made by metal plate, and discharge thorn (2) is evenly distributed on the minus plate both sides.Every side is by 100～400/m
2Be provided with.Discharge thorn (2) is the triangle that shuts out from minus plate (1), and the thorn that will discharge during installation (2) is pulled back with minus plate (1) perpendicular, and the length of discharge thorn (2) is 5～15mm.
More than two serial experiment results show: by plate and the electric field average field intensity formed of thorn plate is 2 times of conventional plate-line formula electric field, and can produce stable corona discharge.The size of corona current can change by length and the number density that changes upward discharge thorn of minus plate (1) (2), and the length and the number density scope of application are: length is 5～15mm; Density is 100～400/m
2Because square being directly proportional of the sinking speed of particle and electric-field intensity in the electric field, average field intensity improves 1 times, and particle average settlement speed should improve 3 times in the electric field.So under the prerequisite that keeps efficiency of dust collection, the electric cleaner volume can reduce 50% at least, floor space and equipment gross investment all will significantly reduce so.
