Detailed description of the invention
In order to make those skilled in the art understand the technical solution of the utility model better, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Please refer to Fig. 1, the structural representation of a kind of embodiment of the electrostatic precipitator 1 of the wet desulfurization system that Fig. 1 provides for the utility model.
As shown in Figure 1, the electrostatic precipitator 1 that the utility model provides has corona discharge device 12 and at least two plates row 11, and corona discharge device 12 can discharge formation electric field.Plate row 11 is formed by the plate body 111 of some plate faces along flow of flue gas direction (as shown by arrows in FIG.), each plate face is oppositely arranged, and on vertical flow of flue gas direction, there is preset distance, therefore the path for flow of flue gas is formed, also be, the plate face of each plate body 111 all falls in ground, and like this, the drop be captured can not gather on plate body 111.
And, the common exhaust gases passes formed for flue gas circulation between the plate body 111 of each adjacent plate row 11, above-mentioned corona discharge device 12 is arranged in described exhaust gases passes, and electric discharge forms electric field in this exhaust gases passes, the electric field line trend of the electric field between each plate body 111 is after (as shown in phantom in Figure 1) can make the droplets of the flue gas entered, moving in plate face to plate body 111, and is trapped on plate body 111.
The utility model adopts plate row 11 to coordinate with corona discharge device 12, and can obtain preferably except fog effect, reason is:
The first, electrostatic precipitator traps fog by electric field, as long as the intensity of conservative control electric field just can obtain trap effect preferably, electric-field intensity is major influence factors, comparatively mechanical type demister, and its disturbing factor is less;
Second, this electrostatic precipitator that the utility model provides adopts corona discharge device 12, it has cutting-edge structure and the electric discharge that can taper off to a point, the electric field aggregation that point discharge is formed is good, when can be applied between two less plate bodys 111 of spacing, and can obtain larger electric-field intensity, as long as rationally arrange position and the version of corona discharge device 12, just can control the state that each electric field unit is all in highfield, meanwhile, demister appearance and size also can be less.
Visible, electrostatic precipitator 1 of the present utility model traps charged drop by electric field, and has stronger electric-field intensity and more trapping area, thus can adapt to the flue gas of high wind speed, relative to mechanical type demister, has preferably except fog effect.
Same plate row's adjacent two plate bodys 111 of 11 and electric field are therebetween defined as an electric field unit.So, spacing between the adjacent plate body 111 of each plate row 11 can be 100mm to 300mm, and this spacing belongs to the pole thin space of this area, and namely the size of electric field unit is less, corona discharge device 12 still can coordinate with it generation respective electric field, very favourable to the miniaturization of electrostatic precipitator.
Further, the plate body 111 of each plate row 11 is being arranged in juxtaposition perpendicular on the flow direction of flue gas, and namely the electric field region of each electric field unit is measure-alike, and the highfield that corona discharge device 12 electric discharge is formed can farthest be limited between plate body 111.
And, described corona discharge device 12 is several, and four described plate bodys 111 around corona discharge device 12 form a space, and each corona discharge device 12 is arranged on the center in this space, strengthen the electric field unit number of electrostatic precipitator 1 on the one hand, obtain stronger electric field; On the other hand, the electric field line that each electric field unit is formed moves towards symmetrical, and the fog particle of trapping is evenly distributed on each plate body, utilizes the trapping area of electrostatic precipitator substantially, improves its arresting efficiency.
Certainly, each plate body 111 also can be staggeredly arranged along vertical flow of flue gas direction, then the electric field region formed with the plate body 111 of same size in the present embodiment will reduce to some extent, be unfavorable for electric-field intensity.
Further, corona discharge device 12 can for being connected with the prickle wire of negative high voltage electricity, and each plate body 111 of plate row 11 is communicated with the earth.Prickle wire has multiple sharp portion be evenly arranged, each sharp portion all tapers off to a point electric discharge, the electrostatic precipitator 1 that very applicable the utility model relates to.
Be connected with the particle release electronics in the prickle wire ionized air of negative high voltage electricity, form negative electric field and point to the electric field line of plate body 111, electronegative drop is moved to plate body 111 against electric field line trend.
Certainly, also can not adopt prickle wire, and replace with the cuspidated discharge component of other tools; Can not also be connected with high-tension electricity, just, the electric-field intensity of acquisition weakens to some extent, has lower demisting efficiency compared with present embodiment; Can also lead to positive electricity to prickle wire, and make corona discharge device 12 have positive polarity, just comparatively negative electric field is slightly poor for electric field stability.
Please refer to Fig. 2 and Fig. 3, the front view being provided with a kind of detailed description of the invention of flue gas demist heater of the electrostatic precipitator 1 in Fig. 1 that Fig. 2 provides for the utility model, broken section goes out electrostatic precipitator 1; Fig. 3 is the top view of the flue gas demist heater in Fig. 2, and broken section goes out electrostatic precipitator 1.
As shown in Figures 2 and 3, the utility model provides a kind of flue gas demist heater of wet desulfurization system, this flue gas demist heater comprises above-mentioned electrostatic precipitator 1 and flue gas heater 2, the plate row 11 of electrostatic precipitator 1 is arranged on the porch of flue gas heater 2, the flue gas flowed out from electrostatic precipitator 1 can continue to flow to flue gas heater 2 through the gap of each plate body 111 of plate row 11, directly heats.
Because electrostatic precipitator 1 has preferably except fog effect, therefore, the amount of droplets contained through the flue gas of electrostatic precipitator 1 is less, less to the corrosivity of upstream device, therefore, the plate row 11 of electrostatic precipitator 1 can be arranged on the porch of flue gas heater 2, on the one hand, plate is arranged 11 gaps and is played the effect of dredging flue gas, and make the flue gas through electrostatic precipitator 1 demist directly enter flue gas heater 2 to heat, without the need to arranging current equalizer in addition, while promoting the heat exchange efficiency of flue gas, reduce Plant arrangement space, reduce device manufacturing cost; On the other hand, electrostatic precipitator 1 and flue gas heater 2 are integrated in one apparatus, not only manufacture, easy to use, can also safeguard that flue gas heater 2 is not corroded preferably.
