Electric cleaner
Invention field
The present invention relates to a kind of electric cleaner, more specifically, relate to the electric cleaner in each independent space that a kind of air mixture that will contain dust separately is transported to shell, wherein dust is to collect described shell by the dust passive electrode of honeycomb, thereby the air of free from dust is discharged into the atmosphere from shell.
Background technology
The various dusts that deduster (dust collector) generally produces industrial place; for example daily dust, zinc oxide, wood, stone, raw cotton, cereal, fur and lead powder; separate with air, and the clean air of free from dust is discharged into atmosphere, make the atmosphere can be by contamination by dust.These dedusters are categorized into electron type and filter type according to their dust collection method.Electric cleaner utilizes electric polarity that dust is separated from air, and the filter type deduster utilizes filter webs that dust is separated from air.
In described deduster, explain the electric cleaner of prior art to Fig. 5 below with reference to Fig. 1.
Hollow shell 1 is provided for and forms the inner space.Inlet 2 is formed at an end of shell 1, and the air mixture that is used for containing dust sucks shell 1 inner space.A plurality of dust passive electrode plates 3 are housed in the enclosure, perpendicular to air-flow direction, when energising, be polarized to positive pole (+), between dust collecting board 3, be placed with a plurality of sparking electrodes 4, along extending perpendicular to air-flow direction, when energising the time is polarized to negative pole (-), and export 5 other ends that are formed at shell 1, be used for discharging the cleaned air that has removed dust in the inner space of shell 1.
Explained later has the dust collection process of the electric cleaner of said structure.
That in industrial place, produce and be diffused into dust in air sucks shell 1 by the inlet that is formed on shell 1 one ends inner space.When being contained in a plurality of dust passive electrode plate 3 in shell 1 inner space, utilize the electro ultrafiltration between dust passive electrode plate 3 and the sparking electrode to collect dust at the inhaled air mixture.Therefore, the cleaned air that free from dust only arranged is by being formed on and the outlet 5 of 2 opposite ends that enter the mouth is discharged in the atmosphere.
Further explain as follows in order in detail.When being forced to flow to outlet 5 by the fan of 2 air mixtures that suck shells 1 inner space that enter the mouth by continuous running, air mixture is through being contained in the dust passive electrode plate of shell 1 inner space.Because dust passive electrode plate has (+) voltage, and the sparking electrode 4 between dust passive electrode plate has (-) voltage, filled with negative electricity through the dust granule in the air mixture of dust passive electrode plate 3 by (-) voltage of sparking electrode 4, thus the dust passive electrode plate 3 that these dust granules with (-) polarity is adsorbed onto have (+) polarity.
On the other hand, be understandable that, for the air mixture that contains dust is sucked in the shells 1 through inlet 2, and the cleaned air that removes dust in the shell 1 is discharged by outlet 5, must or export on any one end in 5 at inlet 2 fan (not shown in the diagram) is housed.
Therefore, owing to are cleaned airs of free from dust through the air of passive electrode plate 3, so shell (1) air of discharging can atmosphere pollution, has reduced environmental pollution as much as possible.
After dust was after a while collected, because the dust quantity that is accumulated on the dust passive electrode plate reaches capacity, dust collection efficiency is extremely acute to descend, and the noise that produces becomes big.In this case, need water to clean dust passive electrode plate, remove the dust of accumulation, therefore need in the inner space of shell 1, provide independent cleaning device.But this cleaning device does not show in the accompanying drawings.
Dust passive electrode plate 3 connected electrically apply (+) voltage and sparking electrode 4 and connect electrically that to apply (-) voltage also be understandable.But these electrical connection arrangements do not show in the accompanying drawings.
Because these electric cleaners of the prior art have plate dust passive electrode, they can handle a large amount of air mixtures simultaneously, therefore are widely used in the large-scale industry field.But they have the shortcoming by this plate dust passive electrode generation as described below.
At first, owing to the electric field that forms around the every sparking electrode 4 is circular, so electric field can not reach some zone of dust passive electrode plate.Therefore, because these zones of the passive electrode plate 3 that electric field does not reach there are not contribution to collecting dust, so the dust capacity gauge weakens.
Secondly, if 2 sizes that enter the mouth are too big, because the flow velocity of porch air mixture is too low, need be with the sectional dimension of inlet 2 relatively less than the sectional dimension of shell 1.Therefore, because obviously different with the flow velocity of peripheral region corresponding to the local velocity of central area in inlet 2 zones, so the dust capacity gauge is inhomogeneous, but along with the zone in the shell 1 obvious difference.Consider to obtaining sufficient dust and collect area and make the size of deduster be tending towards becoming big, and the dust that contains in the air mixture is different and have different proportion along with the material of forming dust, so the dust capacity gauge difference of zones of different becomes bigger.
The 3rd, be whole owing to collect shell 1 inner space of the dust in the air mixture, even therefore a part of shell 1 or some component failure and need repairing or replace also must stop operation of entire equipment.
In order to overcome the shortcoming of plate dust passive electrode, the someone has tested honeycomb dust passive electrode and has replaced dust passive electrode plate and place sparking electrode between honeycomb dust passive electrode.This increases dust passive electrode area and has improved the dust capacity gauge, because the electric field that is formed by sparking electrode can reach the All Ranges of dust passive electrode.But because interior space dimension must increase realistically, the deduster that therefore has honeycomb dust passive electrode can not be applied to the large-scale industry place, and can only be used for little workshop or family uses by limited.
In other words, big if shell becomes, consider from making angle, be difficult to fill all inner spaces with honeycomb dust passive electrode.Therefore, the manufacturing cost that increases makes it can not obtain commercial the application.And because the honeycomb of dust passive electrode becomes too low to the mobile larger interference power that produces of air at the flow velocity than the air mixture in the big inner space, thereby the dust capacity gauge can not improve on an equal basis along with given shell sizes size.
Summary of the invention
The purpose of this invention is to provide a kind of electric cleaner with honeycomb dust passive electrode, it can overcome the problem of the electric cleaner that has dust passive electrode plate in the prior art.In electric cleaner of the present invention, the inner space of shell is divided into a plurality of subspaces.And honeycomb dust passive electrode is all even catches effectively because the dust in the air mixture is by in each subspace all, therefore can make big capacity deduster and strengthen the dust capacity gauge.
Reaching purpose of the present invention is by a kind of electric cleaner is provided, wherein air mixture sucks and is directed in the enclosure space by inlet, dust contained in the air mixture is adsorbed on the dust passive electrode according to the electric polarity of dust passive electrode and sparking electrode, and remove the free from dust cleaned air that dust obtains in the enclosure in the portion space and be discharged into atmosphere, it is characterized in that: partition wall is installed the inner space of described shell is divided into a plurality of subspaces by outlet; The bottom of separating the subspace is connected to inlet by a plurality of entry conductors, and entry conductor is directed to each subspace respectively with the shunting of inhaled air mixture and along different paths; In each subspace of shell, be (-) polarity during with power supply for a plurality of honeycomb dust passive electrodes of (+) polarity and place a plurality of sparking electrode arranged verticals between the dust passive electrode in when power supply; The top of separating the subspace is connected to outlet by guiding each to separate a plurality of delivery channels that remove the cleaned air of dust in the subspace respectively; Each entry conductor forms right-angle bending from an end that connects inlet to the other end that connects shell, but described bending is level and smooth circular arc, so that the air mixture smooth flow; And a plurality of guide vane streamwises are installed in the inside of entry conductor sweep, and air mixture is evenly distributed on the whole flow section.
Therefore, because in electric cleaner according to the present invention, the inner space of shell 11 is separated into independent subspace, each independent subspace can install the honeycomb with superior dust capacity gauge dust passive electrode 15 and with the sparking electrode 16 of the mutual electro ultrafiltration of dust passive electrode.And, because air mixture can suck in the shell 11 in a large number, and, catch dust in air effectively by air being evenly distributed in the shell 11.Deduster of the present invention can be applied to the large-scale industry place.
And, since according to the efficient of deduster of the present invention under the constant volume far above plate deduster, therefore cleaner air is entered in the atmosphere, prevent the pollution of the environment.
In deduster of the present invention, when a part of shell 11 or the damage of some internals, do not need to stop whole system operation and carry out modular repair or replacement.Therefore, can estimate to have the effect that improves throughput rate.
As mentioned above, owing in the single subspace of shell 11, are honeycombs by dust passive electrode 15 with the mutual electro ultrafiltrations collection of sparking electrode 16 dusts, therefore not only the collection area of dust passive electrode broadens, and the electric field that forms around the sparking electrode 16 can arrive all collecting zones.Therefore, owing to improve greatly, compare with massive plate type deduster and can collect more tiny dust for given processing capacity dust capacity gauge.

The specific embodiment
Accompanying drawing 6 is the perspective views according to electric cleaner of the present invention, and accompanying drawing 7 is the vertical cross sections according to electric cleaner of the present invention, and accompanying drawing 8 is the profiles along Fig. 7 center line III-III, and Fig. 9 is the perspective view that expression electric cleaner according to the present invention is mainly constructed.As shown in the figure, deduster of the present invention comprises: shell 11, and described shell 11 forms the inner space and is separated into a plurality of subspaces in vertical direction by partition wall 12; Inlet 13, described inlet 13 is positioned at the outside of shell front side, is used to suck the air mixture that contains dust; A plurality of entry conductors 14, one end are connected to the inlet bottom side, and the other end connects shell 11 front sides, air mixture are shunted and is directed to each following air inlet (lowerplenum) of the subspace of shell 11; A plurality of honeycomb dust passive electrodes 15, described dust passive electrode (15) vertically be contained in shell 11 each separate in subspace and when powering up, become positive pole (+); Sparking electrode 16, each sparking electrode 16 vertically place between the dust passive electrode and become negative pole (-) when powering up; A plurality of delivery channels 17, the one end connects the upside of shell 11, is used for guiding respectively the air that sucks each subspace that it is discharged; And exporting 18, described outlet 18 connects the other end of delivery channel 17, will compile from the air mixture that delivery channel 17 is discharged and it is discharged to the atmosphere.
Entry conductor 14 will be shunted by inlet 13 inhaled air mixtures, and it is directed to the following air inlet of each subspace of shell 11.Entry conductor is turned to the angle formation circular arc of the other end that connects shell 11 from an end that connects inlet 13, and air mixture is flowed reposefully.In addition, in the sweep inside of each entry conductor 14, streamwise is fixed with a plurality of guide vanes 19, thereby air mixture is uniformly distributed on the whole flow region cross section.
And, in the following air inlet of each the independent subspace in shell 11, below dust passive electrode 15 and sparking electrode 16, being fixed with distribution plate 20, distribution plate 20 has a plurality of hole 20a, thereby air mixture is not had partial error's strange land uniform distribution.
To explain the process of utilizing electric cleaner collection dust now with said structure.
The air mixture that contains the dust that produces in industrial site sucks by the inlet 13 that shell 11 1 sides form.The inhaled air mixture is directed in the shell 11 by a plurality of entry conductors 14 that an end is connected to the preceding bottom of shell.Because shell 11 is separated wall 12 and is separated into a plurality of subspaces, so air mixture is directed to corresponding subspace respectively by each entry conductor 14.
When being directed to each sub spaces of shell 11 by the 13 inhaled air mixtures that enter the mouth by each entry conductor 14, air mixture can pass through the sweep of entry conductor reposefully, because entry conductor is made slick and sly circular arc bending.And, because a plurality of guide blades 19 are fixed in the sweep of entry conductor, air mixture flow can concentration of local through the entry conductor sweep time, thus in each porch, subspace of shell 11 with the air mixture uniform distribution on whole flow region.
In the present invention, entry conductor 14 is used for the inhaled air mixture from 13 each subspace that is directed to shell 11 that enter the mouth, and its structure is to form right-angled bend from an end that connects inlet to the other end that connects shell.This end that makes entry conductor connect inlet is higher than the other end that connects shell 11.Like this, when passing through inlet 13 inhaled air mixtures along gravity direction process vertical-path, it flows and quickens, and makes air mixture flow into each subspace of shell 11 fast and reposefully.
In case air mixture enters the subspace of shell 11, it just continues to move upward to the position of the distribution plate 20 with a plurality of hole 20a, and described distribution plate 20 is fixed on below the dust passive electrode 15 and sparking electrode 16 of each subspace of shell 11.When the air mixture that moves upward is run into porose distribution plate 20, before through dust passive electrode 15 and sparking electrode 16, make its flow distribution even.
In case air mixture is through the distribution plate 20 of each subspace of shell 11, it continues to move upward and through the dust passive electrode 15 of honeycomb.Dust contained in the air mixture is caught by the mutual electro ultrafiltration that places the sparking electrode 16 between the dust passive electrode 15 at this.Therefore, the air that flows through dust passive electrode 15 becomes the cleaned air of free from dust.
After this, the cleaned air of free from dust is connected to a plurality of delivery channels 17 on shell 11 tops by an end, is directed and flows out the separation subspace of shell 11.Then, cleaned air collects in the outlet 18 that is positioned at shell 11 tops and is connected to the other end of each delivery channel 17, and is discharged in the atmosphere.
By being understandable that referring to prior art, dust in the air mixture by honeycomb dust passive electrode 15 and place mutual electro ultrafiltration between the sparking electrode 16 of dust passive electrode 15, be adsorbed on the dust passive electrode 15 and be collected.Therefore, omit its detailed explanation here.
In order to make the air mixture that contains dust 13 suck and the cleaned air of free from dust is discharged in the atmosphere by exporting 18, fan (not shown in the diagram) must be housed at inlet 13 or the side that exports in 18 by entering the mouth.Be understandable that if fan is contained in inlet 13 1 sides, then it is the compression air blast; And when fan was contained in outlet 18 1 sides, it was a vavuum pump.
Therefore, owing to being cleaned airs of free from dust, therefore will reduce such as the air-polluting environmental pollution by exporting 18 air that are discharged in the atmosphere.
If the dust collection process in the deduster continues for some time, when the dust quantity on being accumulated in dust passive electrode 15 reached capacity, the dust capacity gauge began to descend, and noise becomes big.At this moment,, need to clean dust passive electrode 15, remove the dust of accumulation as prior art.
In according to electric cleaner of the present invention, supply with honeycomb dust passive electrode 15 (+) voltage by electrical connection arrangement, and supply with each sparking electrode 16 (-) voltage that places between the dust passive electrode 15 by independent electrical connection arrangement.But, do not show electrical connection arrangement in the accompanying drawings.
