Abstract
The utility model discloses an efficient wet desulphurization demister which is composed of a water outlet pipe, a fixing flange, an oblique cone, an acceleration cylinder, a vortex plate, a vortex plate flange and a top cover and is characterized in that the whole device is fixed in a barrel body of a desulfurizing tower through the fixing flange; the upper part of the fixing flange is connected with the oblique cone; the upper part of the oblique cone is connected with the acceleration cylinder; the upper part of the accelerating cylinder is connected with the vortex plate flange; the upper part of the vortex plate flange is connected with the vortex vane; and the upper part of the vortex plate is connected with the top cover. The efficient wet desulphurization demister has the advantages of low resistance, high smoke demisting efficiency up to 90-99%, no blockage and the like, can be widely applied to removal of water and mist in smoke in the wet desulphurization process and has favorable practicability and innovation.
Description
Technical field
A kind of high-efficiency wet-desulfurizing demister of the utility model relates to environmental technology field, is applied to the wet desulfurization flue gas demist.
Background technology
Contain a large amount of water smoke in flue gas after processing through wet desulphurization device, directly discharging causes a large amount of losses of moisture, needs to use demister that water smoke in flue gas is removed.Traditional deflection plate demister adopts ripple packing as the demist moisture-catcher, this demister has many shortcomings, that resistance is larger on the one hand, ripple packing demist poor effect on the other hand, the waste gas water phenomenon usually appears, moreover the life-span of filler is limited, easily produces and stops up, and need to frequently clean and change.
Summary of the invention
The purpose of this utility model is to overcome defects, and prior art is improved, and demist efficient can reach 90% ~ 99%, can reach discharge standard.Its technology is achieved in that and comprises outlet pipe, mounting flange, oblique cone, speed-raising cylinder, spiral board, spiral board flange, top cover, it is characterized in that: whole device is fixed in desulfurizing barrel by mounting flange, mounting flange top connects oblique cone, oblique cone top connects the speed-raising cylinder, speed-raising cylinder top connects the spiral board flange, spiral board flange top connects spinning disk, spiral board top connection top cover.
When flue gas entered demister, setting at this moment, the flue gas wind speed was V
1=2.5 ~ 5m/s; Then flue gas enters the speed-raising cylinder through after oblique cone, due to constriction in flow area, sets flue gas wind speed V this moment
2=16 ± 4m/s; Flue gas enters cyclone plate subsequently, sets speed V this moment
3=11.4m ± 2m/s; Then flue gas leaves cyclone plate through after eddy flow, sets velocity of flue gas V this moment
4=7 ± 2m/s; This moment, flue gas was through the line motion of spinning after whirlwind, clashed into the desulfurizing tower barrel, and the water smoke in flue gas prolongs barrel to dirty after clashing into barrel, was pooled on mounting flange, got back to the desulfurizing tower bottom through outlet pipe; Final flue gas is with V
5=V
1The speed of=2.5 ~ 5m/s is moved in cylinder and is discharged through outlet flue after a period of time.
Know according to experiment, when eddy flow plate number is 15, when spinning disk outlet tangent line and the top board edge tangent line angle α that contact with it=24 °, can reach the fog effect that removes of the best.
Obvious advantage and the effect implemented after this technology are: at first overcome defects, compared with prior art can make demist efficient reach 90% ~ 99%, and not produce obstruction, saved the cost that spray cleans.
Description of drawings
Fig. 1 is the main TV structure of the utility model embodiment, and Fig. 2 is A-A line of vision figure,
Number in the figure, 1. cyclone plate, 2. advance mouth, 3. desulfurizing tower, 4. mounting flange, 5. oblique cone, 6. speed-raising cylinder, 7. cyclone plate flange, 8. top board, 9. outlet flue, 10. outlet pipe.
The specific embodiment
Below in conjunction with accompanying drawing, use embodiment, the utility model is further described:
See accompanying drawing 1,2, whole device is connected in desulfurizing barrel by mounting flange 4, mounting flange 4 upper ends connection oblique cones 5, oblique cone 5 upper ends connect speed-raising cylinder 6, speed-raising cylinder 6 upper ends connect cyclone plate flange 7, cyclone plate flange 7 upper ends connection cyclone plates 1, cyclone plate 1 upper end connection top cover.
See accompanying drawing 1,2, when flue gas entered demister, this moment, the flue gas wind speed was V1=2.5 ~ 5m/s; Then flue gas is through entering speed-raising cylinder 6 after oblique cone, due to constriction in flow area, this moment flue gas wind speed V2=16 ± 4m/s; Flue gas enters cyclone plate 1 subsequently, at this moment speed V3=11.4m ± 2m/S; Then flue gas leaves cyclone plate through after eddy flow, at this moment velocity of flue gas V4=7 ± 2m/s; This moment, flue gas was through the line motion of spinning after whirlwind, clashed into the desulfurizing tower barrel, and the water smoke in flue gas prolongs barrel to dirty after clashing into barrel, was pooled on mounting flange 4, got back to the desulfurizing tower bottom through outlet pipe 10; Final flue gas move in cylinder with the speed of V5=V1=2.5 ~ 5m/s and discharges through outlet flue 9 after a period of time.
