Atomization sprayer carries out work pre-processing.The spray head for enabling the spray thrower 2 being located above catcher 3 is high-pressure nozzle, is set
It is set to high-pressure spraying device 2, certain interval of time opens the spray thrower 2 for being located at 3 top of catcher, and high-pressure nozzle sprays clear water punching
It hits on 3 surface of catcher, can will be attached to dust on 3 surface of catcher and remove clean, raising dust suction dust removing effects.
The outer surface of the capture ball 4 of the exhaust gas dust capture device is provided with several whirlwind fins, in specific implementation,
The setting of whirlwind fin is used for eddy flow exhaust gas dust, is passed through exhaust gas dust, when exhaust gas dust is by capturing ball 4, in whirlwind wing
Under the action of piece, eddy flow is carried out to exhaust gas dust, the vapor and dust in eddy flow flue gas come into full contact under inertia with moisture film,
And then it is adsorbed by moisture film.The exhaust gas dust capture device carries out cyclone adsorbing to exhaust gas dust, and exhaust gas dust is filled
Divide comprehensive absorption, effectively improves the efficiency of absorption.
The capture ball 4 of the exhaust gas dust capture device is folded in upper and lower porous pressing plate 6,7；Wherein, upper and lower porous pressure
Kong Kewei circular hole or regular polygon hole on plate 6,7, with no restriction, upper porous pressing plate 6 porous pressing plate 7 under is parent to concrete shape
Water material.In specific implementation, not only capture ball 4 had been defined by the setting to upper and lower porous pressing plate 6,7, but also can shape
At several dust suctions, dust removing units, initial moisture film is formed on porous pressing plate 7 under in upper porous pressing plate 6, further to flue gas powder
Dirt is adsorbed, and dust suction efficiency of dust collection is improved；In actual operation, the aperture of the upper porous pressing plate 7 under of porous pressing plate 6, which is less than, catches
Catch the size of ball 4.
The catcher 3 of the exhaust gas dust capture device further includes the fixation that both ends are connect with upper and lower porous pressing plate 6,7 respectively
Plate 8 further positions capture ball 4 by fixed plate 8, and fixed plate 8 is water wetted material, can also form initial moisture film,
And then exhaust gas dust is adsorbed, further increase exhaust gas dust adsorption efficiency.The edge ring of fixed plate 8 is equipped with a stainless steel
Ring 10 is fixed by stainless steel ring 10 and cylinder 1.
It is provided with several hole bodies 9 in the fixed plate 8 of the exhaust gas dust capture device, captures ball 4 for accommodating；Its mesoporous
Body 9 may be configured as round or polygon, and concrete shape with no restriction, can accommodate and capture ball 4.In specific implementation, it captures
Ball 4 rests in hole body 9, improves its service life, reduces maintenance and use cost.
The catcher 3 of the exhaust gas dust capture device is fixed in cylinder 1 by supportive grid 11, and dismounting and change is convenient；
In specific implementation, the mode that catcher 3 is fixed in cylinder 1 is not limited in such a way that supportive grid 11 is fixed, optional yet
With other modes being detachably fixed；It specifically can according to the actual situation or the installation fancy setting of skilled worker.
As shown in Figure 1, Fig. 1 shows schematically a kind of cigarette of exhaust gas dust capture device for being provided with two spray throwers 2
Gas dust processing structure block diagram.In actual operation, it is first turned on the spray thrower 2 positioned at 3 lower section of catcher, opens atomization spray
Leaching, and or spray thrower 2 above catcher 3 can be opened simultaneously.At this point, due to capture ball 4, upper porous pressing plate, under it is porous
The hydrophily in 8 smoke contacts face of pressing plate 6,7 and fixed plate, can capture ball 4, upper porous pressing plate, under porous pressing plate 6,7 and fixed
Initial moisture film is formed on the surface of plate 8.
Then, it is passed through exhaust gas dust below the side wall of cylinder 1, after flue gas enters cylinder 1, first passes around down porous pressing plate
7 are adsorbed in advance, are then passed through and are captured ball 4 and fixed plate 8；At this point, flue gas starts eddy flow, eddy flow under the action of capturing ball 4
Vapor and dust in flue gas come into full contact under inertia with moisture film, and then are adsorbed by moisture film.Water droplets and dust continue
Be attached to capture ball 4, upper porous pressing plate, under porous pressing plate 6,7 and fixed plate 8 surface, and then form thicker moisture film until
Water droplet is formed to fall off.
And then, water droplet can condense the water vapour in import flue gas, form bigger water droplet drippage.And due to the parent of flue dust
Aqueous, the water droplet of drippage can further adsorb flue dust during decline.Water droplet is finally dropped in the bottom of cylinder 1, specific
In implementation, the bottom of cylinder 1 may be configured as inverted trapezoidal or other shapes convenient for aggregation water droplet；Last several drops of dripping are gathered into
Dust and wastewater, convenient for the subsequent sedimentation separation for carrying out sewage.
The exhaust gas dust capture device carry out exhaust gas dust adsorption treatment work when, can certain interval of time, open
Spray thrower 2 above catcher 3, high-pressure nozzle spray clear water impact on 3 surface of catcher, can will be attached to catcher
Dust is removed clean on 3 surfaces, improves dust suction dust removing effects.
The invention further relates to a kind of exhaust gas dust method for catching, the technical solution used includes the following steps:
A. start atomizing spray, until forming initial moisture film on catcher 3；
B. it is passed through flue gas, and utilizes capture 4 eddy flow flue gas of ball；
C. exhaust gas dust is adsorbed using the initial moisture film formed, form water droplet and dripped；
D. the water droplet for assembling drippage, obtains dust and wastewater.
Specific steps show themselves in that unlatching atomizing spray so that capture ball 4, upper porous pressing plate, under porous pressing plate 6,7 and solid
Initial moisture film is formed on the surface of fixed board 8.Then, be passed through exhaust gas dust, exhaust gas dust first pass around down porous pressing plate 7 carry out it is pre-
Absorption is then passed through and captures ball 4 and fixed plate 8；At this point, flue gas starts eddy flow under the action of capturing ball 4, in eddy flow flue gas
Vapor and dust come into full contact under inertia with moisture film, and then are adsorbed by moisture film.
Water droplets and dust continue to be attached to capture ball 4, upper porous pressing plate, under porous pressing plate 6,7 and fixed plate 8 table
Face, and then form thicker moisture film and fall off until forming water droplet.And then, water droplet can condense the water vapour in import flue gas, shape
The water droplet of Cheng Geng great drips.And due to the hydrophily of flue dust, the water droplet of drippage can further adsorb flue dust during decline, most
Several drops of dripping are gathered into dust and wastewater afterwards.
Specifically, setting time need to be spaced to be rinsed catcher 3；When carrying out the adsorption treatment of exhaust gas dust,
Every setting time, the spray thrower 2 for being located at 3 top of catcher is opened, high-pressure nozzle sprays clear water impact on 3 surface of catcher,
It can will be attached to dust on 3 surface of catcher and remove clean, raising dust suction dust removing effects.
The foregoing description of the disclosed embodiments is that professional and technical personnel in the field can be realized or using the present invention.
Various modifications to these embodiments will make for those skilled in the art it will be apparent that as defined herein one
As principle can realize in other embodiments without departing from the spirit or scope of the invention.Therefore, the present invention will not
Meeting be limited and the embodiments shown herein, and is to fit to consistent with principles disclosed herein and novel features
Widest scope.
