Fig. 1 is the overall structure sketch map of the utility model.
The specific embodiment
The utility model gas-liquid mixed is dashed atomizing desulfurization and dedusting tower from taking offence, as shown in Figure 1, comprises the air inlet flue 1 and desulfurization and dedusting tower 2 that connect boiler induced-draft fan; The top of desulfurization and dedusting tower 2 is an inducer 21, and air inlet flue 1 is connected in the open top of this inducer 21; The below of this inducer 21 is provided with air and liquid mixer 3 successively, Venturi tube 4 is gentle to spray chamber 5.
The top of air and liquid mixer 3 has comprehensive mixer 31; Comprehensive mixer 31 belows are provided with three component liquid and the refluence member 32 that is provided with at interval, and every component liquid and refluence member 32 are made up of distribution grid with taper diffusion type 321 and the contraction-like refluence plate 322 of back taper that is undertaken in distribution grid 321 belows.
Venturi tube 4 has interflow contraction section 41, trunnion 42 and diffuser 43; The import of interflow contraction section 41 is undertaken in separatory and refluence member 32 belows; Desulfurization and dedusting tower 2 is distribution of gas chamber 7 corresponding to the part of the diffuser 43 of Venturi tube 4; The top of this distribution of gas chamber 7 is provided with collapsible dewatering plate 8, the bottom is provided with water-gas distribution contact plate 9; This distribution of gas contact plate 9 constitutes for the platelet of the spiral distribution at interval of being tilted by polylith, and the diffuser 43 of Venturi tube passes collapsible dewatering plate 8 and water-gas distribution contact plate 9 successively and stretches into gas in spray chamber 5.
Gas is provided with back taper working face 51 towards spray chamber 5, and the below of this back taper working face 51 is provided with the overfall (not shown), leaves gas-water separation section 52 between back taper working face 51 and the distribution of gas contact plate 9.
Desulfurization and dedusting tower 2 is provided with outlet flue 22 corresponding to import and the position between the collapsible dewatering plate 8 (specifically being the position corresponding to the trunnion 42 of Venturi tube 4) of Venturi tube 4.
The inwall of distribution of gas chamber 7 is equipped with water retaining cover 10 in the below of collapsible dewatering plate 8.
The operation principle of the utility model is following:
During use, the alkali lye for preparing is introduced desulphurization plant by water circulating pump, deliver to the alkali lye spray thrower 6 on desulfurization and dedusting tower 2 inducers 21 tops.Flue gas is introduced the mouth that advances of desulfurization and dedusting tower 2 through air inlet flue 1 with certain flow velocity; Flue gas is in the comprehensive mixer 31 of air and liquid mixer 3; Flow velocity is lower, with the abundant condensation by contact humidification reaction of the alkali lye of spray thrower 6 sprays, makes flue-gas temperature reach best reaction temperature.
Alkali lye produces uniform water curtain under the effect of separatory and refluence member 32, after flue gas gets off from comprehensive mixer 31; At first get into the distribution grid 321 of the taper diffusion type in first component stream and the refluence member,, get into the contraction-like refluence plate 322 of back taper again with the preliminary haptoreaction of the liquid on the distribution grid 321; It is big that flow velocity becomes; When flue gas passes through water curtain with bigger flow velocity, its kinetic energy rotation change, the fierce liquid that impacts makes its broken water droplet that nebulizes; Form water smoke, for good reaction condition is created in gas-liquid contact, reaction.Flue gas is crossed the distribution grid 321 through the taper diffusion type in second component stream and the refluence member 32 with bigger speed again afterwards, under the effect of this distribution grid 321, and the redistribution of flue gas and water droplet, kinetic energy is rotation change again, and water droplet is broken thinner vaporific.Liquid in collision, divide and to spatter, in the atomization process, some liquid, to run into the tower wall and form moisture film, increased the gas-liquid contact area, further improved desulfurization degree.Flue gas is through behind the multistage atomizing of air and liquid mixer 3, and state basically reaches capacity.
When the contraction section 41 of the interflow of flue gas entering Venturi tube 4; Because dwindling gradually of sectional area, static pressure also gradates and is kinetic energy in the pipe, and the interior flue gas flow rate of pipe is increased; After adding the multistage atomizing of front; The flue gas state that reaches capacity basically impels gas-liquid to impact mutually, carries out strong atomizing, contact, collision and mass transfer reaction.After flue gas got into the trunnion 42 of Venturi tube, because trunnion 42 basal areas are constant, static pressure dropped to minimum in the pipe, and remains unchanged, and this moment, flue gas flow rate reached peak; After getting into the diffuser 43 of Venturi tube, flue gas flow rate reduces gradually, because the variation in cross section causes the redistribution of air velocity, under the effect of inertia force, exists relative motion between gas-liquid, thereby improves SO
2Removal efficient.Flue gas pours gas towards spray chamber 5 under the guiding of Venturi tube 4, gas and gas carry out violent impact towards the water seal face of spray chamber 5 and contacts, and most flue gas pulls the plug; After entering gas was washed towards spray chamber 5, the inverted cone surface 51 along gas towards spray chamber rose to gas-water separation section 52, enters into distribution of gas contact plate 9; Because water seal face is impacted stirring; Also sticked alkali lye above the distribution of gas contact plate 9, flue dust contacts with alkali lye fully, and grit is captured, sulfur dioxide is neutralized.The gas that process gas purifies towards spray chamber 5 gets rid of Xiang Tabi along the spiral-flow type gap of distribution of gas contact plate 9 and carries out gas-water separation once more; Behind distribution of gas contact plate 9; Get into distribution of gas chamber 7; Flue gas flow rate is slack-off, with flue gas from gas towards spray chamber 5 alkali lye that bring out abundant haptoreaction under suitable condition.Alkali lye on the wall is blocked by water retaining cover 10, and the return-air that falls is towards spray chamber 5, and the flue dust of band water is a Purge gas up to standard afterwards through collapsible dewatering plate 8 dehydrations, through outlet flue 22 in the middle of chimney breast is drained into atmosphere.The efficiency of dust collection of whole system reaches 99.5%, and desulfuration efficiency reaches more than 92%.
Drop under waste water after the desulfurization and dewater unit collection comes together in the blowdown funnel of bottom; Discharge desulfurizing tower again, the ditch with mix through postdigestive lime slurry, the reactant gypsum of generation comes together in sedimentation basin; Through sedimentation basin, depositing reservoir post precipitation, supernatant is introduced clear water reserviors recirculation and is used.
The desulfurization product gypsum is evacuated to mummifying pool by slush pump and carries out the nature mummification.Owing to be doped with various ash contents and Na in the gypsum
2SO
4, had a strong impact on the gypsum quality, so generally as machine brick raw material or road bed course etc.
Circulation fluid should constantly replenish fresh alkali lye (its consumption can be confirmed) in use in debug process, to guarantee desulfuration efficiency.When the recirculated water turbidity improves, for not influencing desulfurized effect, should in time handle (deciding according to practical operation situation), need a part of circulation fluid of discharging regularly, circulation fluid adjustment pH value is disposed to sewage treatment plant again to neutral.
