Detailed description of the invention
In order to understand the utility model in depth, below in conjunction with drawings and the specific embodiments, the utility model is elaborated.
Referring to accompanying drawing 1, the desulfurization concentration that the utility model provides is less than the pneumatic water curtain tower of 10 milligrams and comprises:
Tower body 1, spraying mechanism, demist parts 3, flue gas buffer unit 6 and tower wall diversion component 5.
Tower body 1 is cylindrical, and tower body 1 side, bottom arranges air inlet 12; The center line of air inlet 12 is obliquely installed, and can reduce like this impact and the wearing and tearing of the high speed sulfur-containing smoke gas entering from air inlet to tower body 1 bottom inwall; Tower body 1 side, top arranges exhaust outlet 2; Tower body 1 bottom is liquid return tank 7; Air inlet 12 is higher than the interior liquid level of liquid return tank 7; Flue gas buffer unit 6 comprises: fixed head and deflector; Fixed head is thin-walled hollow cylinder, and cylinder outer wall and tower body 1 inwall are fitted and be connected; Polylith deflector is connected in the inwall of cylinder, and deflector is horizontal by 50 ° of angles; The flue gas that polylith deflector is sent into air inlet 12 is uniformly distributed backward upper guiding; Flue gas buffer unit 6 arranges the position between the inner air inlet 12 of tower body 1 and tower wall diversion component 5; Flue gas buffer unit 6 is near air inlet 12; Because flue gas stream is in the moment that enters tower body 1 inside, its air velocity is very fast, and throughput is also very large, directly impact tower body 1 inwall, not only easily cause the heavy wear of tower body 1 inwall, and flue gas can not effectively fully be contacted with inorganic agent, reduced desulfuration efficiency.
Demist parts 3 are arranged on the position of 2 belows, the inner gas outlet of tower body 1; Spraying mechanism comprises: reservoir 10, woven hose, rotary nozzle 4; One end of woven hose is arranged on reservoir 10 inside, and the other end stretches into and be fixed on tower body 1 inside; Rotary nozzle 4 is connected on the woven hose of tower body 1 inside; Woven hose is arranged on the below of demist parts 3; Rotary nozzle 4 is communicated with woven hose and can rotates freely.Multiple rotary nozzles 4 are set, inorganic agent can fully be contacted with flue gas, greatly improved desulfuration efficiency.
Tower wall diversion component 5 is planar sheet; One end of tower wall diversion component 5 is connected in tower body 1 inwall; The 5 downward-sloping settings of tower wall diversion component; Tower wall diversion component 5 is arranged on the below of rotary nozzle 4.
Wherein, also comprise: return liquid treatment trough 8, infusion pump 9; Tower body 1 side, bottom arranges leakage fluid dram; Leakage fluid dram stretches into back in liquid treatment trough 8; Returning liquid treatment trough 8 is communicated with reservoir 10; Infusion pump 9 is transported to the liquid that returns that returns the processing in liquid treatment trough 8 in reservoir 10.The inorganic agent ejecting and sulfur-containing smoke gas haptoreaction, become waste liquid in rotary nozzle 4, waste liquid flows in the liquid return tank 7 of tower body 1 inside, then enter into back in liquid treatment trough 8 by the leakage fluid dram outside liquid return tank 7, after liquid inorganic agent is returned in the back interior interpolation of liquid treatment trough 8, waste liquid is become to inorganic agent, by infusion pump 9, the inorganic agent returning in liquid treatment trough 8 is sent in reservoir 10 again, so just can make inorganic agent in this water curtain tower, form a circulation, ensure that inorganic agent can Reusability, avoid producing waste liquor contamination environment.
Wherein, spraying mechanism also comprises: circulating pump 11, the first transfusion arm 13, the second transfusion arm 14 and valve.
The branch that the first transfusion arm 13 and the second transfusion arm 14 are woven hose; Two valves are separately positioned on the first transfusion arm 13 and the second transfusion arm 14; The first transfusion arm 13 and the second transfusion arm 14 stretch into and are fixed on tower body 1 inside; Multiple rotary nozzles 4 are connected in respectively on the first transfusion arm 13 and the second transfusion arm 14; The first transfusion arm 13 is arranged on the top of the second transfusion arm 14.
The input of circulating pump 11 is communicated with reservoir 10; The output of circulating pump 11 is communicated with woven hose; Treatment fluid in reservoir 10 is sent into the first transfusion arm 13 and the second transfusion arm 14 by circulating pump 11, sprays treatment fluid by the rotary nozzle 4 being connected on the first transfusion arm 13 and the second transfusion arm 14 to tower body 1 inside.
Wherein, multiple tower wall diversion components 5 are separately positioned on the position of the below 1m of the first transfusion arm 13 and the second transfusion arm 14; Multiple tower wall diversion component 5 downtilt angles are that planar sheet and level are 50 °; The width of planar sheet is 40cm ~ 60cm; Multiple tower wall diversion components 5 are circumferentially uniformly distributed along tower body 1 inwall.Because near inorganic agent droplet tower body 1 inwall interweaves partially sparse, the inorganic agent that clashes into tower body 1 inwall slides and does not substantially absorb SO2 along tower body 1 inwall, for the inorganic agent fully not reacting, so just cause tower body 1 inwall near zone SO2 concentration higher, slide along tower body 1 inwall fully the inorganic agent of reaction flow to the edge of tower wall diversion component 5 time formation processing agent liquid film, the inorganic agent liquid film of down sliding contacts with upwards mobile high concentration SO 2 flue gas, flue gas breaks up liquid film atomization haptoreaction abundant with it, greatly reduce near the SO2 concentration of the flue gas of tower body 1 inwall, the effect of multiple tower wall diversion components 5 of the two-layer annular spread of process, the average SO2 concentration of flue gas is significantly declined.
The desulfurization concentration that the utility model provides is less than the pneumatic water curtain tower of 10 milligrams and after deflector, is distributed in equably under rotary nozzle 4 by the ascending air that flue gas buffer unit 6 is set can makes to enter in tower body 1, be convenient to sulfur-containing smoke gas and contact more equably with inorganic agent, improve desulfuration efficiency; Flue gas buffer unit 6 can reduce impact and the wearing and tearing of the high speed sulfur-containing smoke gas entering from air inlet to tower body 1 inwall simultaneously; By being set, tower wall diversion component 5 make the inorganic agent liquid film fully not reacting sliding along tower body 1 inwall be tilted to down the edge that is drained to tower wall diversion component 5, the inorganic agent liquid film at edge contacts with upwards mobile high concentration SO 2 flue gas, flue gas breaks up liquid film atomization haptoreaction abundant with it, greatly reduce near the SO2 concentration of the flue gas of tower wall, and then the average SO2 concentration of the flue gas of the exhaust outlet discharge that significantly declines; By multiple rotary nozzles 4 are set, inorganic agent can fully be contacted with sulfur-containing smoke gas, and then improve desulfuration efficiency.
