Abstract
The utility model relates to the hole type electric field of an electric dust remover. The utility model is characterized in that hole plate dust removing electrodes respectively communicated with the positive and the negative electrodes of a high-voltage direct-current power supply and an awn-pinking corona electrode are additionally arranged in the inlet loudspeaker of the traditional electric dust remover so as to make the dust particle of gas be charged and partially deposited on the hole plate dust removing electrodes, partial dust particle enters a first electric field after the partial dust particle is precharged, and the partial dust particle is quickly deposited on a pole plate under the action of electric field force. Therefore, the hole type electric field of the electric dust remover has obvious dust a pre-removing and a dust precharging functions and raises the dust removing efficiency of the traditional dust remover, having small size, light weight and low cost.
Description
The utility model belongs to the improvement of cottrell.
In industrial production such as building materials, metallurgy, electric power, chemical industry, generally adopted the flue dust of traditional cottrell at present, carried out dust removal process, purified air, the purpose of protection environment to reach to producing in the production process.Though such cottrell has high dust-collecting efficiency, and the flue dust of suitable high temperature (less than 500 ℃), its volume is big, and steel consumption is many, the price height, horizontal cottrell floor space is bigger.
The purpose of this utility model provides a kind of hole shape electric field arrangement of novel cottrell, to realize the improvement to the traditional electrical dust-precipitator, makes its volume-diminished, and price reduces by 30%.Can reduce simultaneously the floor space of dust-precipitator, improve its dust-collecting efficiency.
Hole shape electric field arrangement of the present utility model is mainly realized by following structural principle.
(being in the horn mouth) installed the corona electrode 5 that communicates with the high-voltage DC power supply negative pole and communicated with the high-voltage DC power supply positive pole in the transition gas passage 2 between the inlet pipeline 1 of traditional dust-precipitator and the dust chamber 3, and make in the transition passage orifice plate of the airflow uniform distribution electrode 4 that gathers dust, thereby form the orifice plate electric field.Its action principle as shown in Figure 1, corona electrode 5 and orifice electrode 4 link to each other with the negative positive pole of the high-voltage DC power supply of 40-50KV respectively, make two interpolars form high voltage electric field.When corona electrode produces corona discharge, make gas ionization become positive and negative ion, they are under the electric field force effect, to two polar motions, make electric field space be full of ion, make the dust granules 14 that enters in the two interpolar dusty gases, charged under electric field action, and to orifice electrode 4 depositions.Therefore the hole shape electric field has and significantly gathers dust in advance and the effect of dust pre-charge, also has simultaneously to make the air-flow (air-flow in the transition passage just) that enters dust chamber along the evenly distribution effect of electric field section.Dusty gas is by the hole shape electric field like this, the part dust granules is deposited on the orifice plate, and another part dust granules is because the effect of air-flow power, have little time to be deposited on the orifice plate and enter first electric field of dust-precipitator, but because these dust granules are charged in advance, under this electric field force effect, deposit on the pole plate very soon, therefore improve the dust-collecting efficiency of conventional dust-precipitator greatly, dwindled the volume of dust-precipitator, reduced cost.
Be described in detail the utility model below in conjunction with accompanying drawing.
Fig. 1 is a schematic diagram of the present utility model.
Fig. 2 is an example structure schematic diagram of the present utility model.
As shown in Figure 2, in the transition gas passage 2 of traditional electrical dust-precipitator, (being in the horn mouth) installed two layers of corona electrode 5, and it places respectively between three layers of orifice electrode 4, forms the hole shape electric field by corona electrode 5 and orifice electrode 4.Corona electrode 5 and framework 6 Joints, the upper end of framework 6 is suspended to the lower end of insulating porcelain bushing 7, and the lower end of framework 6 is with teflon rod 10 and affixed with housing, swings to prevent the effect of wind-engaging power.The outer garden of insulating porcelain bushing 7 and connecting plate 12 Joints, by lead 8, lead 8 is by connecting with high-voltage DC power supply with the fixing porcelain wall bushing 9 of body of wall in the hole.After dusty gas is introduced from inlet pipeline 1, entering transition gas passage 2(is horn mouth) make dust granules very fast charged under the effect of high voltage electric field through the hole shape electric field, and under the electric field force effect, deposit to orifice plate, the dust nationality that is deposited on orifice plate and the corona electrode helps outside rapping apparatus, on the inclined-plane with its portion of falling of shaking, and flow in the ash bucket of dust chamber.Also can the ash bucket dust exhaust be set in the bell-mouthed lower end of import.
And the orifice electrode of said apparatus can make the garden orifice plate, X profiled orifice plate, various ways such as shutter.The porosity of its perforate is that 40-45% is good.
In the said apparatus, but described high-voltage DC power supply separate configurations, also can with the first electric field power supply coupling of cottrell.
In the said apparatus, the described electrode 4 that gathers dust also can utilize the electrode that gathers dust of the original airflow uniform distribution device in the transition gas passage.
In the said apparatus, described corona electrode 5 can adopt needle-like, zigzag or various forms of barbed nail corona electrodes such as netted.
The hole shape electric field arrangement of above-mentioned cottrell also can be installed in going out in the air horn of cottrell.
The utlity model has simple in structure, easily manufactured, for ease of maintenaince reach the advantages such as installation, be not only applicable to the exploitation of new product, and be applicable to the transformation to old dust-precipitator.
