Detailed description of the invention
Core of the present utility model is to provide a kind of high-effective conductive filter pocket electrostatic precipitator, and this deduster effectively can filter dust contained in flue gas, avoids dust to the pollution of air to a greater degree.
The high-effective conductive filter pocket electrostatic precipitator that theres is provided of the utility model for this reason, as shown in Figure 1, is the structure chart of cathode line 1, positive plate 2 and conduction filter pocket 3, illustrates the course of work of high-effective conductive filter pocket electrostatic precipitator.Comprise cathode line 1 and positive plate 2, also comprise and meet the air-flow side conduction filter pocket 3 relative with the side of positive plate 2; Conduction filter pocket 3 other sides except meeting air-flow side all arrange mesh aperture different, for the screen pack 31 of Chalk-dust filtering.In the utility model, three sides of main in the vertical direction arrange screen pack 31, and the side of top and bottom does not arrange corresponding structure, and certainly, top and bottom arrange screen pack and be also fine.Screen pack 31 is all set on three sides, can Chalk-dust filtering more up hill and dale.It should be noted that mentioned here meet air-flow side refer to conduction filter pocket 3 first with the side of air flow contacts, represent it is the side relative with arrow in FIG.Meet edge, air-flow side and anyhow reinforcement 32 is set respectively in direction, in order to strengthen the structural strength of conduction filter pocket 3.The mode that reinforcement 32 can adopt the mode of welding or bolt to fix is connected with conduction filter pocket 3.
Cathode line 1 is in column, vertically arrange in space, cathode line 1 and high voltage source are connected to form high pressure charging area, when flue gas is entered high pressure charging area by deduster (direction of arrow as shown in Figure 1), under the effect of electric field force, dusty gas is electrically isolated, on grit and anion Binding protein after negative electricity, and trend positive plate 2 surface-discharge and depositing.Cathode line 1 and positive plate 2 interval are arranged, and positive plate 2 is arranged along vertical direction equally, and the cross section of many cathode line 1 forms the distribution of orthoscopic, and above-mentioned cross section line is parallel with the plate face of positive plate 2.Inner at deduster, cathode line 1 and positive plate 2 are spaced.Charged dust is attracted by positive plate 2 surface being deposited on positive plate 2, reaches the object of dedusting with this.The closer to positive plate 2, the dust concentration in flue gas is higher, and the relative concentration of dust near cathode line 1 is lower, and most dust all can be attracted by positive plate 2.But mutually repel owing to obtaining electric dust band like electricity and there is part dust to obtain electricity not enough, cause part dust can not be trapped by positive plate 2, and do not continued mobile by the escape dust that positive plate 2 is collected by the effect of electric field force and wind-force, because majority escape dust concentrates near the plate face of positive plate 2, so arrange conduction filter pocket 3 at the side opposite position of positive plate 2, escape dust is entered by the air-flow side of meeting of conduction filter pocket 3, and is undertaken further collecting catching by screen pack 31 pairs of dust.In high-effective conductive filter pocket electrostatic precipitator provided by the utility model, the size of the mesh that the screen pack 31 of Chalk-dust filtering is offered is set to different sizes, in order to filter the dust of different size respectively.
