The baffle plate-type flue gas desulphurization demister has the advantages as follows: the structure is simple; the resistance is small; the demisting efficiency is high; the cost is low, the demisting effect is improved under the condition that the increase of pressure drop is lower, and the normal operation of the desulphurization system is guaranteed.
Description
Technical field
The utility model belongs to the flue gas desulfurization field, is specifically related to a kind ofly use in ammonia desulfurizing process, improves demist efficiency, guarantees the baffle type mist eliminator of the flue gas desulfurization with burr structure of the normal operation of desulphurization system.
Background technology
Ammonia flue gas desulfurization technique is the widely used technology of the attached steam power plant of ammonia enterprise.Find by research, because the inner demister of desulfurizing tower is bad except fog effect, the steam in flue gas carries flue dust and is stained with and sticks on equipment pipe on the one hand, not separated ammonium sulfate solution crystallization on the other hand, cause the place's crystallization of equipment outlet elbow serious, even stop up, impact is produced; Cause simultaneously to a certain degree corrosion with liquid,, there is potential safety hazard in the tube wall attenuation.
At present, the desulfurization demister adopting ammonia method that domestic ammonia enterprise has moved is mostly common demister, and serious except the poor band liquid of fog effect, the equipment cycle of operation is few, can't guarantee that desulphurization system normally moves.
The utility model content
The purpose of this utility model is to overcome defect of the prior art, and provides a kind of simple in structure, under the less condition of pressure drop increase, improves demist efficiency, guarantees the baffle type mist eliminator of the flue gas desulfurization with burr structure of the normal operation of desulphurization system.
The purpose of this utility model is achieved in that the cleaning device, the cleaning device that comprise the demister housing, be located at the demister enclosure interior are provided with nozzle, wherein, the position corresponding with nozzle is provided with fixed head, fixed head is provided with some deflection plates with burr structure, described deflection plate is the isosceles trapezoidal structure of bottom opening, the angle on isosceles trapezoidal structure top is 135 °~150 °, and described deflection plate plate is wide is 200~300mm, and the height of described burr structure is 3~5mm.Spacing between described some deflection plates is 20~25mm.7000~8000/m of density of described burr structure
2At least be provided with two fixed heads in described day with fog housing.
The baffle type mist eliminator of the flue gas desulfurization with burr structure of making according to such scheme, by angle and the band burr structure that deflection plate is set, can realize the water conservancy diversion that stops to drop, flue dust, greatly increased to drop and flue dust stop the seizure chance, be with liquid measure thereby reduce in flue gas; Have simple in structurely, resistance is little, and demist efficiency is high, and is with low cost, under the less condition of pressure drop increase, improves demist efficiency, guarantees the advantage of the normal operation of desulphurization system.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model deflection plate.
The specific embodiment
As shown in Figure 1, 2, the utility model comprises demister housing 1, is located at the cleaning device 4 of demister housing 1 inside, cleaning device 4 is provided with nozzle 5, the position corresponding with nozzle 5 is provided with fixed head 2, fixed head 2 is provided with some deflection plates with burr structure 63, described deflection plate 3 is the isosceles trapezoidal structure of bottom opening, the angle on isosceles trapezoidal structure top is 135 °~150 °, and described deflection plate 3 plates are wide is 200~300mm, and the height of described burr structure 6 is 3~5mm.Spacing between described some deflection plates 3 is 20~25mm.7000~8000/m of density of described burr structure 6
2At least be provided with two fixed heads 2 in described day with fog housing 1.
Demist principle of the present utility model is: when the gas that contains mist was flowed through the utility model with certain speed, due to the inertial impaction effect of gas, mist collided and is attached on burr structure 6 and folding shape plate 3 surfaces with folding shape plate 3 and burr structure 6.The diffusion of mist and gravitational settling make mist form larger drop and with air-flow, move forward to folding shape plate 3 turning angles, owing to turning to centrifugal force and with the surface tension of rubbing action, suction-operated and the liquid of rolling over shape plate 3, making drop increasing, until the drop that gathers is while arriving greatly making a concerted effort of climbing power that the gravity that himself produces surpasses gas and surface tension of liquid, drop just separatedly gets off from folding shape plate 3 is surperficial.Gas, by after rolling over shape plate 3 demisters, is substantially free of mist.Described deflection plate 3 angles for the isosceles trapezoidal structure of bottom opening, its top are that the spacing between 135 °~150 °, deflection plate 3 and adjacent baffle 3 is that the height of 20~25mm and burr structure 6 is 3~5mm, 7000~8000/m of its density
2, be that the applicant solves through test of many times and science the conclusion that draws.At least be provided with two fixed heads 2 in day with fog housing 1, be equipped with some deflection plates with burr structure 63 on described each fixed head 2.
