Abstract
The utility model provides a sticky dust removal device which comprises an upper box body and a lower box body superposed together, wherein the two box bodies are communicated through a U-shaped pipeline at one end; a smoke inlet and a smoke outlet are arranged at the other ends of the two box bodies directly facing to a U-shaped orifice respectively; a radial suspension baffle is connected below the top plates of the two box bodies; and a coarse coating is arranged on the surface of the baffle directly facing to the smoke normal stress. In the utility model, since the normal stress of the smoke generates shear stress on the premise of impact collision and generates a great quantity of backflow at the same time, the smoke regularly goes round and moves forward on the premise of stability and low speed, and the friction coefficient between the smoke and the suspension baffle and the viscosity of the smoke are increased; under the effect of the stress impact collision, the suspension baffle generates resonance to form a fibrillation wave; and under the combined action with the viscosity generated by the smoke friction, an effect of effectively sticking tiny dust can be realized.
Description
Technical field
The utility model relates to a kind of deduster, relates in particular to a kind of sticking grey deduster that flue gas is handled that is used for.
Background technology
Existing flue gas ash removal auxiliary facility generally adopts wet-treating and dry process." high-pressure spraying " technology is adopted in wet-treating; Before spray chamber, be provided with the flue gas flow road of a turbulent flow, make flue gas have the regular hour to reach the dedusting purpose with reverse contact of fog of high-pressure nozzle ejection, but wet-treating sprayed the influence of angle with amount; As spray angle and produce off-set phenomenon; The effect of dedusting is bad, and flue dust can escape in the atmosphere, pollutes.Dry process be forwardly adapted bulky grain flue dust collecting device (whirlwind dust settler); The micronic dust after the special collection and treatment of small-sized bagroom has been adopted at the rear portion; But the dry method dust cost is high, operation sequence is complicated, if misoperation is stuck with paste bag easily; Directly the whole flue gas flow of influence finally becomes a kind of ornaments.
Also there is patent documentation to report the deduster that some are new; A kind of smoke duster is disclosed like CN201959679; It is a tubulose; Make flue gas keep a period of time after flue gas gets into, impurity utilizes air scour to be used for removing the solid entering next stage deduster of filtering material surface attachment attached on the filtering material surface again.But this deduster dust removing effects does not still reach desirable requirement, also must carry out multistage dedusting, drops into higherly, and the scope of application is wideless.
The utility model content
The utility model is exactly in order to overcome the above problems, and a kind of structure, simple to operate is provided, and cost is low, safety energy-conserving environment protection, comparatively perfect flue gas ash removal facility.
In order to achieve the above object; The utility model provides a kind of sticking grey deduster; Comprise upper and lower two casings that stack, two casings are communicated with through the U type pipeline of establishing at one end, and the other end of described two casings is respectively equipped with gas approach and exhanst gas outlet over against the position of the U type mouth of pipe; Described two roof box below all is connected with radially unsettled baffle plate, and described baffle plate is provided with crude coating in its one side facing to flue gas direct stress.
The quantity of each casing Internal baffle can confirm according to the size of smoke evacuation volume and dust content with row's number, and reaching desirable dedusting purpose, and the size of the size of casing and baffle plate can be confirmed according to actual conditions.Establish the 4-10 baffles over against gas approach or exhanst gas outlet in each casing generally speaking; Every row establishes 3-6 piece baffle plate; Every baffles is simultaneously established crude coating over against the direction that flue gas gets into; Increase the friction of flue gas and baffle plate, slow down the preceding line speed of flue gas, thereby reach the purpose that increases flue gas viscosity, dedusting.
Generally be that gas approach is located at the upper box end, exhanst gas outlet is located at the end of lower box.
Prevent that flue gas pressures is excessive; And the unsettled roof box below baffle plate that is connected is blowed to other end motion; So will be provided with the catching sheet that is connected with box bottom over against the first baffles lower end of flue gas, flue gas is had to from the side of baffle plate and space, pass like this, has not only reduced the flow velocity of cigarette power; Reach the effect of dedusting, also avoided the wobble effects of baffle plate.
Long when running time one, when the dust of viscous is too much on the baffle plate, be provided with shoot door in casing side plate center, be convenient to clear up the dust on the baffle plate.And from the side plate of casing, with the ash-digging gate of base plate intersection dust is swept out, avoid accumulation, influence the dust removing effects of deduster.
The utility model produces shear stress through the direct stress of flue gas under the prerequisite of impact; Produce a large amount of backflows simultaneously, make flue gas stablize under the prerequisite of low speed well-regulatedly, increase flue gas and the coefficient of friction of unsettled baffle plate and the degree of adhesion of flue gas around to moving ahead; Under stress impact collision effect; Unsettled baffle plate produces resonance and forms f wave, with the fricative degree of adhesion acting in conjunction of flue gas, can play the effect of effective adhesion adhesion micronic dust.And long-time running; Can not look like bag-type dust influences flue gas flow because of sticking with paste bag, and the cycle of deashing is long, and the deashing program is simple; Only need regularly with member shoot door unlatching up and down; With brush the sticking flue dust cleaning of plate face institute is got final product, draw out flue dust from ash-digging gate then after, shoot door, ash-digging gate are closed.
The utility model is compared with prior art has following beneficial effect:
1, dust removing effects is remarkable, makes the up to standard and minimizing discharging of flue gas;
2, relatively environmental protection has prevented that effectively the micronic dust that is mingled with in the flue gas is discharged in the atmosphere;
3, the utility model is simple in structure, cost is low, and long-time running does not have the possibility of manpower and mechanical failure, has reduced maintenance cost.
