Description
Technical field
The present invention relates to a kind of deduster, especially a kind of energy-efficient centrifugal electrostatic dust collector.
Background technique
Industrial gasses are when being discharged, in order to avoid environmental pollution, it is necessary to reach discharge standard.Therefore it needs before discharging
It is dusted decontamination processing；The deduster of common industrial gasses has cyclone dust collectors, electrostatic precipitator and sack cleaner.
Cyclone dust collectors are one kind of dust-extraction unit.Dust removal mechanism is that dust-contained airflow is made to rotate, by means of centrifugation
Grit is separated from air-flow and is trapped in wall by power, then so that grit is fallen into ash bucket by gravity.
Although traditional cyclone dust collectors have the following advantages that 1) structure is simple, low cost, small in size, operation maintenance side
Just, it can be manufactured with a variety of materials.2) pressure loss is medium, and power consumption is small, high dust collection efficiency, up to 85% or so, efficiently
Up to 90% or so.3) it is suitable for dust load variation greatly, high temperature, high pressure and corrosive dusty gas can be recycled directly
Dry dust.4) there is no moving component, operational management is easy.But traditional cyclone dust collectors trap the efficiency of < 5 μm of particles not
Height can only generally be used as pre- dedusting.
The working principle of electrostatic precipitator is dusty gas by being electrically isolated when high-voltage electrostatic field, grit and anion knot
On crossed belt after negative electricity, tends to anode surface electric discharge and deposit.It is useful to purification gas or recycling in the industry such as metallurgy, chemistry
Grit.Make gas ionization using electrostatic field to make dust particles be adsorbed onto the collecting method on electrode.The air in strong electrical field
Molecule is ionized as cation and electronics, and electronics, which marches on towards, encounters grit in anode process, make grit is negatively charged to be adsorbed onto positive quilt
It collects.Ionize flue gas using high voltage electric field, the dust charged in air-flow separates under electric field action with air-flow.
Conventional electrostatic dust removal device has the advantage that 1) initial stage efficiency of dust collection can reach 99%, and it is below thin to trap 1um
Micro dust.2) processing exhaust gas volumn is big, can be used for the occasion of high temperature, high pressure and high humidity, can continuously run, and is able to achieve automation.
3) has the characteristics that low-resistance, the electric precipitator pressure loss only 100~200Pa.But still have the disadvantages that 1) power consumption and gas
Body dust content is directly proportional, and when dust content is high, energy consumption is just high.2) the technical level requirement for manufacturing, installing and managing
It is higher.3) efficiency of dust collection is influenced by dust specific resistance, generally to specific resistance less than 104~105 Ω cm or be greater than 1010~
The dust of 1011 Ω cm, if not taking certain measure, efficiency of dust collection will be affected.4) 30g/cm3 is greater than to initial concentration
Dusty gas pretreatment unit need to be set.5) do not have off-line maintenance function, once equipment breaks down, or transport in spite of illness
Row, or can only shutdown maintenance.Simultaneously because conventional electrostatic deduster does not have the effect of centrifugal force, needed in electrostatic precipitator
Rapping apparatus is installed, otherwise dust accumulation will seriously affect dust removing effects.
Sack cleaner is a kind of dry type dust filtration device.It is suitable for trapping tiny, dry, non-fiber dust.Filter bag
Using the filter cloth or nonwoven felt of weaving at being filtered using the filtration of fabric to dusty gas, when containing
After dust and gas body enters sack cleaner, particle is big, heavy dust falls into ash bucket, contain since the effect of gravity settles down
There is the gas of relatively fine dust when passing through filtrate, dust is purified gas by detention.
Traditional sack cleaner is due to being filtered gas by filter cloth, in the mistake that industrial gasses are dusted
It will receive biggish resistance in journey, to reduce air pressure, outer bound pair industrial gasses needed to be pressurized.Sack cleaner pair simultaneously
The removal effect of the dust of Pm2.5 in industrial gasses or so is poor；And filter cloth is needed to be replaced frequently, troublesome maintenance.
There are also a kind of centrifugal electric static dust removers in the prior art, such as Chinese utility model patent " centrifugal electrostatic precipitation
Device " Publication No. CN2587518Y, which discloses a kind of centrifugal electric static dust remover, cyclone type dedusting is filled
It sets and is combined into one with electrostatic precipitator, shape is cylindrical body, and cathode assembly is arranged in center, and shell is anode, is contained
Dust and gas body is entered by cylindrical body lower tangential, and dust-laden particle is captured under the action of centrifugal force and electrostatic force, purification gas by
The discharge of cylindrical body upper tangential.
Above-mentioned centrifugal electric static dust remover is due to two-in-one by cyclone dust collector and electrostatic precipitator；By electrostatic precipitator
Anode be set as shell, cathode assembly is set on transmission shaft.Although the small of Pm5-10 can will be less than in industrial gasses
Dust removal, does not need to add pretreatment unit.But realize the minute dusts function for removing and being less than Pm2.5-10 in industrial gasses
Only electrostatic precipitator, the cyclone type dedusting of energy are equivalent to a pretreatment unit of electrostatic precipitator.It is above-mentioned centrifugal
The dust-cleaning principle of electrostatic precipitator is identical with electrostatic precipitator, only changes the arrangement of the electrode of electrostatic precipitator.
Therefore above-mentioned centrifugal electric static dust remover only just corresponds to combine cyclone dust collector and electrostatic precipitator
It uses；Electrostatic precipitator is directly mounted on to the top of cyclone dust removal device.Cyclone dust removal device is only to industrial gas
Body plays an Effect of Pretreatment；Dedusting is completed in electrostatic precipitator after the completion of industrial gasses pretreatment.Cyclone type dedusting
Device and electrostatic precipitator are the absolutely not any synergistic effect of function for realizing itself, and above-mentioned centrifugal electrostatic removes
Dirt device is that cyclone dust collectors are combined with the accumulation of electrostatic precipitator.The electrostatic on above-mentioned centrifugal electric static dust remover top removes simultaneously
Dirt device does not have the effect of centrifugal force, needs to install rapping apparatus in electrostatic precipitator, and otherwise dust accumulation will be seriously affected and be removed
Dirt effect.

Centrifugal pan 5.The setting at least above centrifugal pan 5 of two-stage enables to centrifugal pan 5 to provide enough centrifugal force.
The above-mentioned strong centrifugal electrostatic dust collector of high speed mainly includes the following two dedusting stage in the process of work:
1) centrifugal dust-removing
Industrial gasses are entered in outer cylinder 1 by air inlet 11, due to being equipped with inner cylinder 2 in outer cylinder 1；Therefore inner cylinder 2 and outer
Cavity between cylinder 1 forms dedusting cabin；Since industrial gasses are entered in outer cylinder 1 by the tangential direction of outer cylinder 1, industrial gasses are being removed
Vortex is formed in dirt storehouse, therefore under gravitational and centrifugal forces, the dust of most of Pm5-10 in industrial gasses or so
And biggish dust throws to the inner wall of outer cylinder 1, and settles downwards along spiral way.Transmission shaft 3 passes through cover board 12 simultaneously
One end is connect with extraneous driving device, and driving device drives transmission shaft 3 to rotate, and the rotation of transmission shaft 3 drives axial blade 6 to rotate,
Industrial gasses are drawn into inner cylinder 2 by axial blade 6 by the bottom of inner cylinder 2, so that forming upward air-flow in inner cylinder 2；Industry
During gas flows up in inner cylinder 2, since transmission shaft 3 drives centrifugal pan 5 to rotate, industrial gasses by it is multistage from
After cartridge 5, the dust of Pm5-10 or so in industrial gasses thrown to the inner wall of inner cylinder 2 step by step, and by the through-hole 21 on inner wall 2 into
Enter into dedusting cabin；It is settled under gravity in dedusting cabin.To pass through centrifugal dust-removing for 90%- in industrial gasses
95% or more the dust removal greater than Pm2.5-10.
2) electrostatic precipitation
Industrial gasses continue flowing from bottom to top after centrifugal dust-removing, quiet due to being provided on 2 top of inner cylinder
Electric field；The electrostatic field is located at 5 top of centrifugal pan.Therefore industrial gasses are got rid of 90%-95% or more by centrifugal pan 5 and are greater than
After the dust of Pm5-10, by further dedusting when passing through electrostatic field above centrifugal pan 5.By electrostatic field to industrial gasses into
Row electrostatic precipitation can trap 1um fine solid particle below since electrostatic precipitation initial stage efficiency of dust collection can reach 99% or more；And
It is big to handle industrial gasses amount, has the characteristics that low-resistance, the electrostatic precipitator pressure loss only 100~200Pa；Therefore industrial gasses exist
The dust for being less than Pm2.5-10 in industrial gasses can be got rid of after electrostatic precipitation.Industrial gasses after final dedusting are by going out
Air port 13 is discharged.
The great advantage of the strong centrifugal electrostatic dust collector of high speed is industrial gasses first under the action of powerful centrifugal force,
The barrel that the dust of 90%-95% or more in industrial gasses is thrown to inner cylinder 2 step by step using multistage centrifugal disk 5, into dedusting cabin,
Cavity i.e. between inner cylinder 2 and outer cylinder 1.However traditional cyclone dust collectors utilize the flow velocity centrifugal dust-removing of itself, centrifugal force compared with
It is small thus can not by industrial gasses 90% or more dust remove.
Through the gas after centrifugal dust-removing under the action of axial blade 6, continue in inner cylinder 2 from bottom to top to upstream
It is dynamic, and pass through electrostatic field, fine dust remaining in industrial gasses is efficiently removed.In entire dust removal process, due to not having
The pressure at expulsion of dust-removal cloth-bag and dedusting sum, the industrial gasses flowed from bottom to top are in entire dust removal process almost without resistance
By centrifugal electrostatic dust collector, so work efficiency is high, whole service process is very energy saving for centrifugal electrostatic dust collector, while dedusting
Effect also produces the variation of matter, and the industrial gasses dustiness after being centrifuged the energy-efficient deduster dedusting of electrostatic can be down to
10mg/m3Left and right.
The inner cavity of outer cylinder 1 is divided into two spaces by inner cylinder 2 and outer cylinder 1 by the above-mentioned strong centrifugal electrostatic dust collector of high speed, is made
In industrial gasses the vortex of dust and ascending air from spatially being separated；Ascending air is avoided to take away the micro- of vortex sedimentation
Small dust.Multistage centrifugal disk 5 is set in the top of axial blade 6 simultaneously, increases centrifugal force, therefore can be realized industrial gasses
The barrel that the dust of middle 90%-95% or more throws to inner cylinder 2 enters dedusting cabin, to effectively improve efficiency of dust collection.
Therefore above-mentioned centrifugal electrostatic dust collector has the advantage that
A, dust removing effects significantly get a promotion, so that the powder that industrial enterprise's industrial gasses are discharged in process of production
Dirt quantity is greatly reduced, and effectively improves the environment that air quality is depended on for existence with us.Has analysis of statistical data, industrial gas
Body generally can achieve 40-60% or so to the contribution rate of Pm2.5；Therefore the discharge amount for reducing dust in industrial gasses, from
And the pollution to environment can be effectively reduced.
B, low energy consumption, and energy conservation can reach 60%-70% or more, it is possible to make enterprise that the operation of deduster be effectively reduced
Cost.Such as, the iron and steel enterprise of 10,000,000 tons of an annual output, the installed capacity of deduster is generally at ten thousand kilowatts of 6-8 or so, according to section
Electricity 60% calculates, and can economize on electricity per hour ten thousand kilowatts of .3.6-4.8, and the annual working time calculated by 8000 hours, can save every year
Hundred million degree of electricity of electric 2.8-3.8, every degree electricity are calculated according to 0.5 yuan, every year can be with 200,000,000 yuan of using electricity wisely cost or so.
C, the strong centrifugation energy-efficient deduster of electrostatic of high speed is not due to having cloth bag and rapping component and a device, in use process
Non-maintaining operation substantially may be implemented, operating cost is also available to be effectively reduced.
D, the strong centrifugation energy-efficient deduster of electrostatic of high speed is due to being three-dimensional arrange so its occupied area is than traditional dedusting
Device is 3-5 times small.
