Abstract

The utility model relates to an improved electric dust collector used for industrial dust collection. A coronal line device and a plate assembly for dust collection are respectively hung on a supporting device and a hanging seat which are in electric field. The mode is adopted that the middle and the lower parts of the coronal line are pulled tightly by gravity rods instead of the original big and small frames. Both ends of the adjacent middle and lower gravity rods are fixed through regulating screw rods to integrate each row of coronal lines in the whole electric field. The right side of the middle gravity rod is provided with a vibration-beating device for making sideway vibration and beating. The executing of the utility model can reduce 18.4 percent of the device weight. Besides, the interelectrode distance adjustment problem existing in the mode of utilizing a frame to fix the coronal lines is solved.

Description

Corona dust collector

The utility model relates to a kind of improved electric cleaner that is used to collect industrial dust.

Existing electric cleaner is mainly traditional thread binding by corona

, dust collection plate dress

, compositions such as big frame, erecting by overhang, rapping apparatus, airflow distribution device, shell parts such as (and ash buckets) and electric supply installation.Corona wire and power cathode are connected, dust collection plate and anodal connection (ground connection), so formed the principle of the electric Games Li Yong Static electric attraction fine dust of cathodic electricity hachure and anode dust collection plate composition, after the high-temperature flue gas that has dust entered electric Games by airflow-distribution board, powder dust particle was charged, and under the effect of electric Games power, be deposited on respectively on dust collection plate and the corona wire, when dust deposit arrived certain thickness, then rapping was removed.The upper and lower of corona wire is supported respectively and is fixed on the big frame that makes with shaped steel, and by big frame, corona is traditional thread binding Hang in the incubator of electric cleaner case top,, add the dust collection plate dress because each electric Games will install a pair of big frame

Put on top On the lower flange of two horizontal I-beams of case top, correspondingly increased the length of relevant other part, so weight of equipment is heavier.Another problem that exists is after equipment is gone into operation, as when big small frame temperature distortion occurring, regulates the die opening difficulty, has influenced efficiency of dust collection and equipment normally moves.

In view of the problem that above-mentioned prior art exists, task of the present utility model is that a kind of improved electric cleaner will be provided, and to alleviate weight of equipment, is convenient to regulate die opening again.

Task of the present utility model is finished as follows:

1, with former hang at the corona of electric cleaner case top traditional thread binding

And dust collection plate dress

Change respectively on the steel pipe that hangs over electric Games inner supporting device and the flap seat of the horizontal I-beam of case top bottom on, cancelled incubator, and the length that has shortened dust collection plate, hung bar etc.

2, in order to keep corona wire to be in vertical tensioning state, in the middle part of corona wire, the bottom is fixed on the gravity rod with bolt, nut, has cancelled large and small framework, has alleviated weight of equipment.In order to improve the Strong degree and the rigidity of corona wire, become the en pipe of fillet to be welded into a rectangular tube by two corona wire, and on pipe, weld prickle or blade.

3, between the two ends of adjacent middle part gravity rod, bottom gravity rod, adjusting screw(rod) is installed, every row's corona wire of whole electric Games is linked to be an integral body, except that the stability that has guaranteed electric Games, and can pass through adjusting screw(rod), regulate the size of die opening.

The utility model can alleviate weight of equipment 18.4%, and solve the existing adjusting die opening of the frame fixation corona wire mode problem of utilizing after implementing.

Below in conjunction with accompanying drawing the utility model is described in further detail:

Fig. 1 is the utility model structure master pseudosection.

Fig. 2 is a corona wire system architecture enlarged drawing.

Fig. 3 is the cutaway view of Fig. 2 along the A-A line.

Fig. 4 is a blade type corona wire sectional drawing.

Fig. 5 is a barb type corona wire sectional drawing.

With reference to Fig. 1, Fig. 2, the dust collection plate dress

(12) hang on the flap seat (4) below housing (6) the two horizontal I-beams in top (2), hanging bar (13) is to be welded by a band steel and a steel pipe, and fixing by otic placode and bolt and dust collection plate (3).Corona is traditional thread binding

(14) device is on the steel pipe (1) on the electric Games inner supporting device, and supporting arrangement is made up of base (15), electroceramics pillar (16) and steel pipe (1).For considering insulation, need to keep a determining deviation between the two ends of steel pipe (1) and the housing wallboard (11).Base (15) is welded on the housing wallboard (11), and electroceramics pillar (16) insulation is installed between the two.The middle part of corona wire and bottom are fixed on middle part and the bottom gravity rod (8), (10) with bolt, nut, on the right side of middle part gravity rod (8) rapping apparatus (7) are installed, and carry out the side direction rapping, to guarantee good rapping effect.Rapping apparatus (7) is by bearing (17), beater (18), rapping crossbeam (19), electroceramics pillar (20) and base (21) are formed, for considering insulation, need to keep a determining deviation between rapping crossbeam (19) and the housing wallboard (11), base (21) is welded on the housing wallboard (11), and insulation column is installed between the two.

With reference to Fig. 3, traditional thread binding for solving corona

The temperature distortion problem, gravity rod can be by two band steels, and also available steel pipe or channel-section steel make.Corona wire (5) is clipped between two band steels, and respectively bore two screws at the gravity rod two ends, between adjacent middle part gravity rod (8), bottom gravity rod (10) two ends, by the staggered adjusting screw(rod) (9) of installing of medial and lateral screw, make every row's corona wire of whole electric Games be linked to be an integral body guaranteeing the stability of electric Games, and regulate the size of die opening by adjusting screw(rod).

With reference to Fig. 4, blade type corona wire (5) becomes the en pipe (22) and the blade type discharge electrode (23) of fillet to form by two, and this type corona wire is applicable to the flue gas of low concentration dust.

With reference to Fig. 5, barb type corona wire (5) becomes the en pipe (22) and the prickle arrester stage (24) of fillet to form by two, and this type corona wire is applicable to the flue gas of high concentrate dust.
