Abstract
The utility model discloses a desulfurizing tower, including the tower body to and the thick liquid pond, flue entry, the rectification layer that from bottom to top set gradually in the tower body, spray layer, defroster and flue and export, the rectification layer constitute by a plurality of root circles shapes or square pipeline that the level set up parallel arrangement, flue gas entry set up between rectification layer and thick liquid pond. The flue gas velocity of desulfurizing tower rectification layer section department has been improved on the rectification layer, and the turbulence of gas -liquid two -phase interface is strengthened, air film thickness attenuate, and the mass transfer rate coefficient improves, the fast increase of cigarette simultaneously can slow down liquid drop falling speed, therefore can make thick liquid dwell time extension in desulfurizing tower, increases the soak time, reaches the purpose that improves desulfurization efficiency.
Description
Technical field
The utility model relates to a kind of desulphurization plant, particularly relates to a kind of fume desulfurating absorption tower.
Background technology
At present, fume desulfurating absorption tower operationally, due to flue gas flow field skewness, causes desulfuration efficiency in absorption tower variant, and when desulfuration efficiency requires very high (ultra-clean discharge), general spray void tower is difficult to reach desulfuration efficiency requirement.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of desulfurizing tower with flue gas fairing, and this device can improve the distribution of gas state of desulfurizing tower inside greatly, optimizes desulfurizing tower flow field, improves the desulfuration efficiency of desulfurizing tower.
The utility model is achieved by the following technical solution: a kind of desulfurizing tower, comprise tower body, and the slurry pool from bottom to top set gradually in tower body, smoke inlet, rectification layer, spraying layer, demister and exhanst gas outlet, described tower body middle and lower part is provided with a smoke inlet, described rectification layer is that described smoke inlet is arranged between rectification layer and slurry pool by being horizontally disposed with some circles arranged in parallel or square pipe is formed.
Further, described rectification layer circle or square pipe are nonuniform mutation operator.
Further, described rectification layer is 1 layer or multilayer.
The utility model compared to existing technology, there is following beneficial effect: the utility model arranges the distribution of gas state that rectification layer substantially improves desulfurizing tower inside, owing to being configured with rectification Rotating fields, the flue gas can optimized on the whole cross section of desulfurizing tower is uniformly distributed, and greatly optimizes desulfurizing tower flow field.Due to the segmentation effect of rectification layer piping, make flue gas evenly enter desulfurizing tower desulfurization zone, former flue gas is fully broken, form multiply shunting flue gas and liquid comes into contact, this embodies obvious effect to the utilization rate making full use of desulfurizing tower, adds the desulfurization degree of desulphurization plant.On the other hand, after arranging rectification layer, desulfurizing tower rectification layer section part flue gas flow rate improves, gas-liquid two-phase interfacial turbulence is strengthened, air-film thickness is thinning improves mass transfer rate coefficient, and rectification layer top defines one deck turbosphere, further increases mass transfer rate coefficient; Cigarette speed increases and can slow down drop decrease speed simultaneously, thus can make slurries increased resident time in desulfurizing tower, increases soak time, reaches the object improving desulfuration efficiency.
Accompanying drawing explanation
Fig. 1 the utility model structural representation.
Fig. 2 the utility model rectification Rotating fields schematic diagram.
Wherein: 1-spraying layer, 2-rectification layer, 3-smoke inlet, 4-slurry pool, 5-demister, 6-flue outlet.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described.
As shown in Figure 1, 2.A kind of desulfurizing tower, comprise tower body, and the slurry pool 4 from bottom to top set gradually in tower body, rectification layer 2, spraying layer 1, demister 5, flue outlet 6, described tower body middle and lower part is provided with a smoke inlet 3, described rectification layer 2 is that described smoke inlet 3 is arranged between rectification layer 2 and slurry pool 4 by being horizontally disposed with some circles arranged in parallel or square pipe is formed.
Further, described rectification layer 2 circle or square pipe are nonuniform mutation operator.
Further, described rectification layer 2 is 1 layer or many groups.
The course of work that the utility model is complete is as follows:
Flue gas enters desulfurizing tower by smoke inlet 3, from bottom to top by rectification layer 2.Due to the segmentation effect of rectification 2 layers of piping, make flue gas evenly enter desulfurizing tower desulfurization zone, former flue gas is fully broken, form multiply shunting flue gas and fully react with the slurry liquid contacts sprayed from top to bottom from spraying layer 1, reach desulfurized effect.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
