Detailed description of the invention
Better the present invention program is understood in order to make those skilled in the art person, below in conjunction with the accompanying drawing in the embodiment of the present invention, clear, complete description is carried out to the technical scheme in the embodiment of the present invention, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, should belong to the scope of protection of the invention.
With reference to shown in Fig. 1, a kind of smoke eliminator, comprises gas cleaning unit, absorbent feeding unit, slurries oxidation unit and gypsum dehydration unit.Gas cleaning unit comprises exhanst gas outlet flue 1 and is located at demist section 21, spraying layer 22, the absorber portion 23 in tower body from top to bottom, at least one wet electrical dust precipitator 3 is provided with between exhanst gas outlet flue 1 and demist section 21, this wet electrical dust precipitator 3 can be arranged in tower body, also can independently be arranged on tower body outside, wet electrical dust precipitator 3 is also connected with heating blower 31.Absorbent feeding unit comprise be connected with absorber portion 23 by pipeline slurry tank 41, be connected in first pump housing 42 on pipeline and be located at for stirring the first agitator 43 of slurries in slurry tank 41, in the present embodiment, absorbent is lime stone suspension.Slurries oxidation unit comprises the second agitator 51 be located in absorber portion 23 and the oxidation fan 52 passed into by air in absorber portion 23.Gypsum dehydration unit comprise with second pump housing 61 be connected bottom absorber portion 23, circulator 62, thin pulp case 63, the 3rd agitator 64 be located in thin pulp case 63, for carrying the belt filter 65 of finished product gypsum and the 3rd pump housing 66 for liquid in thin pulp case 63 being pumped into absorber portion 23.
With reference to shown in Fig. 2-5, the below of spraying layer 22 is provided with synergistic device layer 24, it comprises at least one group of flow-disturbing parts, flow-disturbing parts comprise be connected to tower body inwall brace summer 244, be connected to multiple first body 241 of brace summer 244 upper surface and be connected to multiple second bodys 242 of brace summer 244 lower surface, certainly for the tower body that tower diameter is less, flow-disturbing parts can save brace summer 244, are directly connected on the inwall of tower by the end winding support of the first body 241 and the second body 242.Diameter is first body 241 of D and the second body 242 are fixedly connected on brace summer 244 upper and lower surface respectively by fastener.Parallel laying between adjacent first body 241, and distance is S, parallel laying between same adjacent second body 242, and distance is S, the vertical range up and down of the first body 241 and the second body 242 is H, ensures H≤3D, S:D=1-1.5,50≤D≤150mm, 50≤S≤200mm.Between first body 241 and the second body 242, parallel interval is arranged, i.e. the lower position in the second body 242 gap between two adjacent first bodys 241.In order to reach desirable desulfurized effect, can two groups of flow-disturbing parts be set up and down abreast, the first flow-disturbing parts namely in top and arranging in the same way between the second flow-disturbing parts of below.Also the first flow-disturbing parts being positioned at top can be arranged in certain anglec of rotation abreast with the second flow-disturbing parts being positioned at below.In order to alleviate the weight of flow-disturbing parts, the first body 241 and the second body 242 are tubular structure.First body 241 and the second body 242 all adopt FRP, 2205,2507 or 1.4529 materials, and brace summer 244 adopts carbon steel, and outer setting is anticorrosion.Worn and torn by the slurries that spraying layer 22 sprays to prevent body, also in order to shunt slurries, can arrange deflector 243 respectively directly over the first body 241, this deflector 243 can be reverse V-shaped structure, also can be inverted U structure, in the present embodiment, it be for being inverted angle steel.
When pending flue gas from the below of flow-disturbing parts through the gap the second body 242, because space diminishes, the flow velocity of flue gas increases, flow-disturbing effect is formed from the flue gas passed through between adjacent segment, and the flow velocity of flue gas reduces, flue gas afterwards between adjacent segment converges again by the gap between the first body 241, the flow velocity of flue gas becomes large again, its with spray above the first body 241 and slurries formed and clash into, because slurries are through the shunting action of deflector 243, more effective turbulence is formed again between slurries and flue gas, thus add the time of contact of flue gas and slurries, the mixed effect of flue gas and slurries is better.According to external diameter and the pending flue gas flow difference of tower body, the quantity of the first body 241 and the second body 242 can adjust, and the number of superposition group up and down of flow-disturbing parts also can correspondingly adjust.
Workflow of the present invention is, is added by agstone in slurry tank 41, and the first agitator 43 constantly stirs it, ensures that the slurries in slurry tank 41 are in suspended state.Lime stone suspension is delivered in the absorber portion 23 in tower body by first pump housing 42, before being delivered in tower body, is also furnished with lime stone slurry return duct.Liquid in second 51 pairs, agitator absorber portion 23 constantly stirs.Liquid in absorber portion 23 is pumped into spraying layer 22 by the 4th pump housing 221.Flue gas enters in tower body from the passage being located at tower body sidewall, it moves upward and to be uniformly distributed after synergistic device layer 24, the reverse haptoreaction of liquid sprayed with spraying layer 22, under the reaction temperature and pH value condition of the best, in flue gas, most sulfur dioxide, flue dust are neutralized, and washing also falls in absorber portion 23 along with desulfurization slurry.Flue gas after washing continues to move upward and enters demist section 21, removes drop.This demist section 21 is also accompanied with fresh water (FW) flusher.Flue gas enters wet electrical dust precipitator 3 after demist section 21, and this wet electrical dust precipitator 3 entrance arranges guiding device, and flue gas is evenly entered in it.The subsidiary hot wind supply system of wet electrical dust precipitator 3, i.e. heating blower 31, and spray irrigation system, established technology water flows in wet electrical dust precipitator 3 from B punishment, and the waste water of simultaneously discharging through wet electrical dust precipitator 3 recycles.Flue gas is disposed in air by exhanst gas outlet flue 1 after wet electrical dust precipitator 3.
In absorber portion 23, also constantly stir the second agitator 51 by oxidation fan 52 input air oxidation reaction occurs, generate gypsum, absorber portion 23 has enough volumes, ensures the time of staying needed for gypsum crystallization.Liquid in absorber portion 23 is pumped into spraying layer 22 again by the 4th pump housing 221, constantly carries out circular response.
Gypsum slurries in absorber portion 23 is delivered to cyclone 62 by second pump housing 61, and cyclone 62 underflow enters belt filter 65, and its top flows to into thin pulp case 63, and the slurries in thin pulp case 63 are delivered in absorber portion 23 by the 3rd pump housing 66 again and carry out circular response.Gypsum slurries obtains finished product gypsum through belt filter 65.
Above-mentioned detailed description of the invention is used for explaining and the present invention is described, instead of limits the invention, and in the protection domain of spirit of the present invention and claim, any amendment make the present invention and change, all fall into protection scope of the present invention.
