Abstract

The utility model relates to an electrostatic precipitator which is characterized in that an anode annulus is arranged inside the shell and a dust removing device is arranged at the bottom of the anode annulus. The utility model has the advantages of that the dust removal is in time, the back corona phenomena is not easy to happen; and the precipitator delivers the dust to around the dust hopper and the dust is cleaned by a dust brusher; the collected dust directly drops in the dust hopper, consequently, the dedust efficiency of the electrostatic precipitator is high.

Description

A kind of electric cleaner
Technical field:
The utility model relates to a kind of deduster, particularly a kind of electric cleaner.
Background technology:
For a long time, the smoke and dust treatment of Industrial Stoves is the control atmosphere pollution always, improve the emphasis of environmental quality, the electric cleaner technology because of its mechanism advanced person, efficient stable, the saving energy, reliable operation, maintenance is simple and operating cost is low is used widely.In recent years, follow China joined WTO, the background success of application for organizing the Olympic Games, the enhancing of whole national power and the environmental quality demand that improves day by day, environmental emission standard is strict day by day, and that extensively carries out now is overall control and is not more than 100mg/Nm 3Discharge standard, require higher area and enterprise to propose 80mg/Nm 3, 50mg/Nm 3Even stricter index, the discharge standard that external advanced iron and steel enterprise carries out is 30mg/Nm 3And back corona phenomenon easily takes place in traditional deduster collection high resistivity dust, and traditional deduster adopts vibration dust-cleaning mode, the easy secondary fly-up of dust.According to domestic statistics, the electric cleaner that calendar year 2001 put into operation in the past, actual efficiency of dust collection are 98.5%, and thermoelectricity industry concentration of emission is many at 250mg/Nm 3More than, the metallurgy industry concentration of emission is many at 100-150mg/Nm 3More than.The efficient of dispatching from the factory of these equipment far can not satisfy new environmental emission standard.
Summary of the invention:
The electric cleaner that provides a kind of efficiency of dust collection high is provided the purpose of this utility model.
To achieve these goals, the technical solution of the utility model is as follows: a kind of electric cleaner, comprise the housing that is provided with import and outlet, the housing below is provided with ash bucket, be provided with negative electrode row in the housing, housing also is provided with cathode rapping and negative electrode is hung, it is characterized in that the anode endless belt is arranged in the housing, the inboard, two ends of anode endless belt is provided with rotating shaft, wherein a rotating shaft is connected with the electric-motor drive that is located at housing, all there is corresponding with it negative electrode row anode endless belt both sides, and there is deashing device with matching anode endless belt both sides.
Advantage of the present utility model is that this deduster deashing is timely, and back corona phenomenon be difficult for to take place, and this deduster delivers near the ash bucket ash by ash brush deashing, and the dust of collection directly falls into ash bucket, so the efficiency of dust collection height of this electric cleaner.
Description of drawings:
Fig. 1 is a structural representation of the present utility model
The specific embodiment:
Below in conjunction with drawings and Examples the utility model is elaborated.
A kind of electric cleaner, comprise the housing 1 that is provided with import and outlet, housing 1 below is provided with ash bucket 2, be provided with negative electrode row 3 in the housing 1, housing 1 also is provided with cathode rapping 4 and negative electrode hangs 5, and it is characterized in that has anode endless belt 6 in the housing 1, the inboard, two ends of anode endless belt 6 is provided with rotating shaft 7, wherein a rotating shaft is connected with the electric-motor drive that is located at housing, and all there is corresponding with it negative electrode row 3 anode endless belt 6 both sides, and there is deashing device 8 with matching anode endless belt 6 both sides.Electric cleaner among the figure has two groups of anode endless belt 6 and associated negative electrode row 3, and negative electrode row 3 is in the 6 inside and outside even distributions of anode endless belt.The lower end of anode endless belt 6 is stretched in the ash bucket 2.Deashing device 8 is for being positioned at the ash brush of anode endless belt 6 bottoms.In order to obtain better ash-removal effect, the lower end of anode endless belt 6 is stretched in the ash bucket 2, and the ash brush is located in the ash bucket 2, and dust is difficult for flying up like this, avoids the dust secondary fly-up.
The negative electrode of this deduster is connected with the high voltage source negative pole, and plus earth under effect of electric field, forms electric current between the two-stage, air generation ionization.Feed dusty gas when between electrode, the negative ions of two interpolars motion will make grit charged attached on the grit.Under effect of electric field; the grit of positively charged is to negative electrode row 3 motions; electronegative grit anode endless belt 6 motions; because the scope of corona zone is very little; therefore identical with negative electrode anion is by bigger corona outskirt anode endless belt 6 motions of scope; and the major part that enters in the dusty gas of interpolar is also passed through at the corona outskirt; so most grit is electronegative; also deposit thereon towards anode endless belt 6 electrode movements; have only the grit ash positively charged of minority and be deposited on the lead, dusty gas is discharged in the atmosphere after purifying.The dust of deposition on the negative electrode row 3 by cathode rapping 4, shakes dust stratification and falls in the ash bucket 2.Above dust-cleaning principle is identical with the traditional electrical deduster, but because anode endless belt 6 rotates the dust of deposition is in time seen off, therefore be difficult for taking place back corona phenomenon, and the dust of deposition is through 8 cleanings of ash brush, dust stratification directly falls into ash bucket 2, is difficult for taking place the dust secondary fly-up.
Because the utility model difference with the prior art only is anode endless belt 6 and is positioned at the deashing device 7 of anode endless belt 6 both sides, so other part same as the prior art such as negative electrode row 3, cathode rapping 4 and negative electrode are hung 5 etc. and are not repeated them here.
