Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain this utility model, is not used to limit this utility model.
Refer to Fig. 1, embodiment of the present utility model provides a kind of fume desulfurizing tower, including be vertically arranged and in be provided with the tower body 1 of desulfurization cavity 11, it is sequentially arranged the poly-liquid pool 2 in described desulfurization cavity 11, desulfurization mechanism 3, demister 4 from the bottom to top, described desulfurization mechanism 3 includes the gather qi together plate 31 that at least two sets gradually from the bottom to top, it is provided with multiple gather qi together hole 311 on each described gather qi together plate 31, above each described gather qi together hole 311, is provided with a shower nozzle 32;Wherein, the gather qi together hole 311 on adjacent two described gather qi together plates 31 is crisscross arranged.
For convenience of description, the present embodiment is as a example by three strata gas plates 31.nullWhen specifically arranging,The air inlet 12 of fume desulfurizing tower can be arranged on tower body 1 sidewall、Gas outlet 13 arranges tower body 1 top,When carrying out desulfurization,Flue gas is entered in desulfurization cavity 11 by air inlet 12,Owing to gather qi together plate 31 uses loose structure,When flue gas is entered, under the effect of lower floor's gather qi together plate 31, its flow velocity is reduced,Flue gas is sprayed desulfurization by shower nozzle 32 while the gather qi together hole 311 through lower floor's gather qi together plate 31,Owing to the gather qi together hole 311 on adjacent two described gather qi together plates 31 is crisscross arranged,The non-coaxial setting in gather qi together hole 311 on the most adjacent two gather qi together plates 31,So that flue gas needs to change through the flow direction during gather qi together plate 31 of intermediate layer,I.e. be converted to horizontal movement successively by moving upward、Move upward,It makes the flow velocity of flue gas again be reduced,Thus again improve the efficiency of spray desulfurization;Owing to the gather qi together hole 311 on upper strata gather qi together plate 31 is crisscross arranged with the gather qi together hole 311 on intermediate layer gather qi together plate 31, i.e. gather qi together hole 311 on upper strata gather qi together plate 31 is coaxially disposed with the gather qi together hole 311 on lower floor gather qi together plate 31, flue gas is made to flow to again change after intermediate layer gather qi together plate 311, flow velocity reduces again, thus by thorough for flue gas desulfurization, again improve desulfuration efficiency.
Wherein, when gather qi together hole 311 is arranged, can be as shown in Figure 2, multiple gather qi together holes 311 are arranged on described gather qi together plate 31 formation gas gathering ring in the form of a ring, in order to ensure the harmony of gather qi together, can be uniformly arranged as multiple by gas gathering ring outside interior, concrete, it is provided with two gas gathering rings on the present embodiment gather qi together plate 31, wherein in order to ensure harmony, is provided with in the middle part of gather qi together plate 31;Also can be as it is shown on figure 3, gather qi together hole 311 be evenly arranged in matrix on described gather qi together plate 31.Above two mode all can reduce the effect of flue gas flow rate, but when specifically arranging, the distance between adjacent two gather qi together holes 311 on each gather qi together plate 31 is unsuitable excessive or too small, it is excessive that to be easily caused gather qi together hole 311 on gather qi together plate 31 less, thus reduce flue gas flow, too small, do not have the effect reducing flue gas flow direction between adjacent two gather qi together plates 31, and then cause flue gas flow rate without substantially reducing.Therefore when specifically arranging, the distance between adjacent two gather qi together holes 311 is generally 10~20 times of upper port aperture, gather qi together hole 311.
In order to reduce the flow velocity after flue gas enters desulfurization cavity 11 further, the present embodiment is additionally provided with a filter mesh layer 5 between described desulfurization mechanism 3 and described poly-liquid pool 2, on the one hand it can avoid the impurity of larger particles to enter desulfurization mechanism 3 causing gather qi together hole 311 to block, on the other hand reduce flue gas flow rate.Corresponding, when air inlet 12 is arranged, need to be arranged between described filter mesh layer 5 and described poly-liquid pool 2.
In order to strengthen gather qi together effect, described gather qi together hole 311 is the bellmouth that an internal diameter is gradually reduced from the bottom to top, so that flue gas stream is constantly gathered when by gather qi together hole 311 in the middle part of gather qi together hole 311, it is conducive to the spray desulfurization of shower nozzle 32;And, owing to flue gas unavoidably existing the impurity such as more dust, under long-term accumulated, the blocking to gather qi together hole 311 is easily caused after impurity spray, gather qi together hole 311 is set to the upper port bellmouth less than lower port by the present embodiment, it is conducive to impurity to flow out from gather qi together hole 311, decrease impurities accumulation in the probability in gather qi together hole 311, reduce the probability of gather qi together hole 311 blocking.In order to ensure gather qi together effect, described in the present embodiment, the tapering of bellmouth is traditionally arranged to be 1:1~5, is preferably arranged to 1:2.
Owing to there is more impurity in poly-liquid pool 2, process for the ease of follow-up deslagging, poly-liquid pool 2 described in the present embodiment is the most diminishing bullet of internal diameter and its lower end is connected with a solid-liquid separator 6, it is set to bullet beneficially impurity move to bottom poly-liquid pool 2, and then by solid-liquid separator 6, impurity is separated with acidic liquid.
Compared with prior art, flue gas is disperseed by this utility model by the multiple gather qi together holes on gather qi together plate, and on the one hand it reduce the flow velocity of flue gas, the most individually carries out spraying desulfurization to the flue gas after dispersion, improves desulfuration efficiency;Gather qi together hole on adjacent two gather qi together plates is crisscross arranged so that flue gas flow direction after lower floor's gather qi together plate changes, and again reduces flue gas flow rate, improves desulfuration efficiency simultaneously.
The above detailed description of the invention of the present utility model, is not intended that the restriction to this utility model protection domain.Any various other made according to technology of the present utility model design change and deformation accordingly, should be included in this utility model scope of the claims.
