Detailed description of the invention
As shown in Figure 1,2,3, 4, a kind of high-efficiency layered formula electric cleaner, comprise air inlet smoke box 1, the smoke box 2 of giving vent to anger, discharge electrode system, dust collector pole system, ash bucket 10 and housing, described air inlet smoke box 1 inside is provided with two-layer airflow-distribution board 11, airflow-distribution board 11 is porous plate, and the hole on plate is circular hole or square hole.Air inlet smoke box 1 is the changeover portion between flue and electric field, and flue gas will complete small pipeline cross section by air inlet smoke box 1 to the heavy in section diffusion of electric field through air inlet smoke box 1, airflow-distribution board is set and is conducive to keep flue gas flow rate, the inhomogeneity balance transition of Flow Field Distribution.Flue gas enters into discharge electrode system and dust collector pole system after by air inlet smoke box 1, by to discharge electrode system and dust collector pole system high-pressure, in the time that dusty gas passes through two interpolar inhomogeneous fields, under highfield effect around discharge electrode, first gas be ionized, and making powder dust particle charged, the powder dust particle after charged is adsorbed by the steel plate 7 of corona wire 4 and dust collector pole system respectively under the effect of electric field force, thereby reaches dedusting object.Wherein discharge electrode system comprises the discharge electrode fixed mount 3 that some rows are arranged in parallel and is fixed on the parallel corona wire 4 on fixed mount, the spacing that same discharge electrode fixedly adds the corona wire 4 on frame is 160～200mm, on discharge electrode fixed mount 3, hull outside is provided with several electromagnetic rapping devices 5, twitch up and down by electromagnetic rapping device 5, thereby drive discharge electrode fixed mount 3 to move up and down, thereby make the dust that on fixed mount, corona wire 4 adsorbs fall to ash bucket 10.Described dust collector pole system comprises the dust collector pole fixed mount 6 that some rows are arranged in parallel and is fixed on the steel plate 7 on fixed mount, described dust collector pole system also includes the mechanical shaking device 8 corresponding with some row's fixed mounts, on one end near air inlet smoke box 1, described dust collector pole fixed mount 6 bases, be provided with bevelled the holding of tool and hit anvil 9, described mechanical shaking device 8 includes transmission device, beater and rapping shaft, described beater is installed on and holds on the corresponding rapping shaft hitting directly over anvil, adjacent beater adopts the setting of 150 DEG C～195 DEG C dislocation angles, by being set, rational shaking cycle can improve efficiency of dust collection, in many cases, be interrupted rapping and can reduce reentrainment of dust 1/2-2/3 than continuous rapping, tail gas after treatment is discharged via the smoke box of giving vent to anger, but overflow dust owing to may comprising part in the tail gas of discharging, therefore need trough plate 21 be set at the entrance point of the smoke box of giving vent to anger, the device that described trough plate 21 is similar shutter, its principle is to utilize the inertia force of remaining dust in flue gas to trap the grit of effusion electric field again, it also has the function of improving air-flow distribution and controlling secondary fly-up simultaneously, and be provided with rapping apparatus in the bottom sheet that approaches of trough plate 21, can carry out vibration dust-cleaning to trough plate 21.
