The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and embodiment.
Among Fig. 1, deduster body 1 structure comprises an expansion chamber 2, length 3m, three electric fields, length 5.9m; Expansion chamber 2 one sides are import loudspeaker 4, are provided with three uniform boards 7 in it, have the processing of pre-dedusting and big dust particle, and it is big to have solved shaft furnace furnace roof furnace bottom dust concentration,＞15g/m
3Electric field length is longer, efficiently solves the shaft furnace high concentration soot emissions problem that moment in when material produces of collapsing.Bottom at expansion chamber 2 and each electric cleaner 3 is provided with ash bucket 5, and conveying device is delivered to the raw material plant batching again with the ash content of receiving.Electric cleaner 3 one sides of final stage are provided with outlet loudspeaker 6, set out a mouthful frid in it.
Sidepiece arm sinker mechanical vibrator mode is adopted in the anode rapping of electric cleaner 3 of the present utility model, vibrating rod adopts steel pipe, connect with positive plate by the welding link plate, make the normal direction vibration acceleration transmission on the pole plate even, accekeration is significantly improved, the heavy 9.1kg of hammer, heavier than conventional beater, and then improved ash-removal effect.
Cathode rapping adopts top electromagnetic rapping mode.The rapping power transmitting of electromagnetic rapping hammer is from top to bottom, can obtain satisfied ash-removal effect with less rapping power, has effectively reduced the influence of the efficiency of dust collection decline that reentrainment of dust causes.
Anode 10 adopts the 480C template, and negative electrode 11 adopts integral tube thorn line.
1, die opening adopts the same pole span of wide spacing 400mm, captures this special flue gas of palletizing shaft furnace high resistivity dust preferably.
2, anode and cathode suspension mode have all adopted the top suspention, the form that the bottom freely overhangs, laterally static, normal direction is spacing, retractable up and down, and die opening does not change, solved the shaft furnace high-temperature flue gas effectively and changed the influence of (120-200 ℃) thermal deformation die opening, deduster fault-free when variations in temperature is taken place, guarantee the equipment high efficiency operation, solved the influence of shaft furnace flue-gas temperature variation deduster.
Among Fig. 2, negative electrode top electromagnetic rapping comprises that negative electrode back timber 8 and negative electrode bottom girder 9, negative electrode back timber 8 are hung 13 by high pressure suspension rod 12 with the high pressure of dust remover roof and be connected, and high pressure is hung 13 and is connected with the electromagnetic vibrator 14 that is arranged on the factory building top; Negative electrode bottom girder 9 connects by bottom girder connecting plate 15; The integral tube thorn line of lifting negative electrode 11 on negative electrode back timber 8.This structure has formed the whole discharge system of stablizing mutually, freely suspending in midair, has advantage aspect thermal deformation resistant and the assurance die opening.Negative electrode 11 adopts pipe thorn lines, and its steel tube section is thick, the intensity height, and good rigidly, indeformable not breaking under abominable flue gas condition stopped the disconnected fault that goes offline of existing deduster.The corona of its needle tip can produce strong electric wind, and the rapid anode of dust is moved, and has overcome because of assembling the corona blocking phenomenon that dust produces near the needle point.The cathode line discharge inception voltage of rigidity is low, and strength of discharge is big, has high spark discharge voltage, high electric-field intensity, the launch point of dispersion and uniform current distribution characteristic.Negative electrode top electromagnetic rapping mode, the rapping power transmitting of its electromagnetic rapping hammer from top to bottom, can obtain satisfied ash-removal effect energetically with less shaking, effectively reduced the problem that efficiency of dust collection that reentrainment of dust causes descends, simultaneously because hanging, beating of cathode rapping is the structure of separating, make the insulator of the support load that directly do not withstand shocks, can prolong its life-span, its characteristics that have also comprise: accurately control, and the impact strength of vibrator and rapping frequency can be controlled by PLC; Monomer structure can guarantee that vibrator uses for a long time; Need not to lubricate, reduced maintenance workload; Avoid maintenance, electromagnetic vibrator did not need regularly to adjust or maintenance in its work period; Owing to be mounted in the factory building top, do not give housing with shock transfer, avoided the fatigue of material.
Among Fig. 3, the anode rapping comprises pole plate suspention beam 16, and suspend in midair on it anode 10 upper ends, and the lower end is connected with trip rod 17; In trip rod 17 1 sides anode rapping shaft 19 is housed, it is made up of anode rapping shaft 18 and a plurality of anode beater 20.Because anode 10 has adopted 480c type positive plate, the groove on it is easy to absorb dust, and the flanging of both sides has increased the rigidity of pole plate, also can prevent the secondary fly-up of dust, helps the good communication of vibration acceleration, is easy to deashing.The sidepiece mechanical oscillation have been adopted in the anode rapping, make the normal direction vibration acceleration transmission of pole plate even, and accekeration is significantly improved, and then has improved ash-removal effect.Anode beater 20 is " bean sprouts type " structure, has the less radius of gyration under same rapping power, help dwindling the shared space of rapping apparatus, and service life is longer, and has stopped to fall to hammer into shape phenomenon.
Flow distribution evenness is the prerequisite that improves efficiency of dust collection.Traditional method is to adopt stifled way to force air-flow to be evenly distributed, and its shortcoming is that the high wearing and tearing of local velocity are big, and distribution grid is short service life.This deduster has adopted choked flow to add the flow guiding type airflow distribution device at import loudspeaker 4, and the aperture is increased to Φ 85 under the constant situation of three layers of porous plate percent opening, has reduced wearing and tearing, has improved the life-span.
Operation principle of the present utility model is: when dusty gas enters electric cleaner air inlet loudspeaker by admission line, dusty gas is because of being subjected to the effect that gas distribution grid resistance and expansion chamber section enlarge, movement velocity is reduced rapidly, and the heavier particle of some of them just loses speed and settles down.Gas distribution grid makes dust-contained airflow be evenly distributed along whole electric field section simultaneously.After dusty gas enters electric field, feed high-voltage DC power supply, then near electrode, produce corona phenomenon, near the gas ionization making because negative electrode connects transformer (1.2A/72KV).Behind the gas ionization, produced zwitterion, and acted on the exhaust gas and dust particle surface of having stage fright, made powder dust particle charged and move, be deposited on the anode at last to its opposite polarity electrode by static.Two electrode systems all have rapping apparatus, and when beater periodically beat two-pole device, the dust that adheres to was thereon shaken off, and dust falls into the bottom ash bucket, and discharge and deliver to raw material and reclaim through unloading ash conveying device.The flue gas that has been cleaned is entered in the atmosphere through chimney through blower fan by deduster outlet loudspeaker again.
