XPromptly returning ground with short grained dust pollutes.Low temperature in addition, also strengthened the equipment of carrying the emptying flue gas, the internal corrosion of managing logical and chimney, because can make flue gas condensing go out the acid aqueous solution of band.Its three, economy (equipment investment and operating cost) and the aspect such as manipulate unsatisfactory place is arranged.So above-mentioned deficiency has seriously restricted generally promoting the use of of existing multi function flue gas cleaner.
The purpose of this utility model is: be the shortcoming at above smoke eliminator, the infant industry desulfurating dust removing device for flue gas of a kind of classification dedusting and grading desulfurization is proposed, its desulfurization and efficiency of dust collection are all very high, and reduce the internal corrosion of carrying emptying flue gas equipment and pipeline.
The technical solution of the utility model is, it includes scrubbing tower, and Venturi tube, baffle means, filter, two-stage (operating) water nozzle, alkaline liquid pool, demister and flue gas heating chamber etc. are equipped with in the center in the tower body.Flue dust in the high-temperature flue gas is carried out the level Four dedusting, to SO
2And SO
3Three grades of absorptions through super-dry and heating, improve the heat buoyancy that flue gas spreads to wet flue gas aloft, have reduced the internal corrosion of carrying emptying flue gas equipment and pipeline.
It is as follows that the utility model is described in further detail in conjunction with the accompanying drawings and embodiments:
Fig. 1 is the desulfurating dust removing device for flue gas structural representation;
Fig. 2 is the baffle means structural representation.
Among Fig. 1: 1. baffle means; 2. shell (carbon steel, liner resistant material); 3. filter (acid-resistant stainless steel silk screen); 4. (operating) water nozzle; 5. (operating) water nozzle; 6. alkaline liquid pool; 7. demister (acid-resistant stainless steel silk screen); 8. high-temperature flue gas heating chamber; 9. Venturi tube; 10. gas approach; 11. emptying exhanst gas outlet; 12. smoke outlet tube; 13. alkalies import; 14. alkalies liquid head piece; 15. discard solution discharge port; 16. slag liquid floss hole; 17. ring-like pipe
As shown in Figure 1, a Venturi tube (9) is equipped with at the center of shell (2), in the trunnion upper end of Venturi tube (9) (operating) water nozzle is housed, and in the outlet lower end of Venturi tube (9) baffle means (1) is housed; In the middle and lower part of shell (2) filter (3) is housed, a ring-like pipe (17) is housed, 8~10 (operating) water nozzles are housed on this pipe on this filter top; In shell (2) middle and upper part one annular alkali lye pond (6) is housed, smoke outlet tube (12) is introduced in the alkali lye in this pond; A demister (7) is housed on smoke outlet tube.Between shell (2) top cover and demist (7) a flue gas heating chamber (8) is housed, this heating chamber is communicated with the upper end of Venturi tube (9).Device is for erectting, and shell (2) can be cylindrical shape, also the side's of can be bodily form.
High-temperature flue gas enters Venturi tube (9), washings (industrial fresh water or seawater) are by the trunnion top ejection of (operating) water nozzle (5) from Venturi tube (9), according to the Venturi-tube action principle, at the trunnion position, flue gas flow rate increases rapidly, and spray washing water atomizes at once, and gas, liquid and solid fully mix and fierce collision, solid flue dust and heat in the flue gas are taken away SO by water
2And SO
3Effectively absorbed by water smoke.Flue gas goes downstream, and runs into baffle means (1) and turns back 180 ° with the minimum pressure loss, flows to filter (3) equably, removes the dust in the flue gas in filter again.Flue gas is accepted the water smoke spray of (operating) water nozzle (4), the 4th dedusting by behind the filter (3).SO in the flue gas
2, SO
3Water smoke spray by under (operating) water nozzle (4) spray is absorbed for the second time by water.Down, flue gas imports in the alkaline liquid pool (7) through smoke outlet tube (12), under the alkalies effect, removes SO wherein for the third time
2And SO
3Wet flue gas continuation is upwards gone, and through demister (7), removes water droplet, dry and heating in flue gas heating chamber (8) again, and finally dried hot flue gas is arranged in the air through conveyance conduit and equipment.To sedimentation basin and neutralization pond, the clean neutral water after the processing can recycle use to washes from slag liquid floss hole (16) row.
The utility model has following characteristics:
1, flue gas process level Four dedusting: the first order is Venturi tube; The second level is to be sprayed by (operating) water nozzle (5) Water smoke washing; The third level is the filtration of filter (3); The fourth stage is by (operating) water nozzle (4) The water smoke washing of ejection. Flue gas is through three grades of desulfurization: the first order is the water of (operating) water nozzle (5) ejection Mist absorbs; The second level is the water smoke absorption by (operating) water nozzle (4) ejection; The third level is at alkalies Alkali liquor absorption in the pond (6). So desulfurization dust-removing efficiency is very high, below lingemann blackness 1 degree, Dust removal efficiency can reach 98%, and desulfurization degree can reach 95%.
2, utilize the heat of the high-temperature flue gas that boiler discharges to add the low-temperature flue gas that thermal purification has been crossed, do not need other Outer thermal source has been saved newly added equipment investment and energy expenditure.
3, flue gas desulphuization rate can be realized two-stage control, if when 60-70% is only required in desulfurization, can not carry out the third level and absorb, and is about to alkalies and releases from alkaline liquid pool (6), allows flue gas directly enter demister (7).If require desulfurization, then to carry out the third level and absorb greater than 70% o'clock.
