Abstract
The utility model discloses a strong reflowing device for a semi-dry desulfurizing tower of a circulating fluidized bed. The strong reflowing device for the semi-dry desulfurizing tower of the circulating fluidized bed comprises the desulfurizing tower (1), and is characterized in that a flow guiding ring (2) surrounded by a plurality of flow guiding plates (3) is arranged at the inner top of the desulfurizing tower (1). The flow guiding ring (2) surrounded by the flow guiding plates (3) is arranged at the inner top of the desulfurizing tower (1), so that flue gas forms a strong counterflow after ascending to the flow guiding ring (2), thus further enhancing return of granules in the tower and improving the bed density of the granules in the tower to increase Ca/S ratio in the fluidized bed; therefore, the utilization ratio of a desulfurizing agent and the desulfurizing efficiency are improved and the production cost is reduced; and the strong reflowing device for the semi-dry desulfurizing tower of the circulating fluidized bed further has the characteristic of simple implementing structure.
Description
Technical field
The utility model relates to a kind of circulating fluid bed semi-drying method desulfurizing tower, the strong inverse flow device that particularly a kind of circulating fluid bed semi-drying method desulfurizing tower is used.
Background technology
Circulating fluidized bed desulfur is a kind of desulfur technology that is used for the boiler tail flue gas desulfurization.Boiler smoke gets into from the desulfurizing tower bottom;, Venturi tube gets into the bed body after integrating air-flow; Near Venturi tube outlet, in bed, spray into desulfurizing agent and an amount of atomized water, in the uphill process in desulfurizing tower with flue gas in thinization thing react the formation desulfurization.The flue gas of existing desulfurizing tower internal upper part after desulfurization directly leaves, and make that the utilization rate of desulfurizing agent is lower, and the single desulfuration efficiency is low, thereby improved production cost.
The utility model content
The purpose of the utility model is, a kind of circulating fluid bed semi-drying method desulfurizing tower strong inverse flow device is provided.The utility model can improve the utilization rate and the desulfuration efficiency of desulfurizing agent, thereby reduces production cost.
The technical scheme of the utility model: a kind of circulating fluid bed semi-drying method desulfurizing tower strong inverse flow device, comprise desulfurizing tower, it is characterized in that: described desulfurizing tower inner top is provided with the baffle liner that is surrounded by some deflectors.
In the aforesaid circulating fluid bed semi-drying method desulfurizing tower strong inverse flow device, described deflector becomes 10～14 ° of settings with the outer wall of desulfurizing tower.
Compared with prior art; The utility model is provided with the baffle liner that is formed a circle by some deflectors through the top in desulfurizing tower, makes to rise to here by flue gas the back forms strong inverse flow, has strengthened further that tower is endocorpuscular to be returned; Improved the endocorpuscular bed density of tower; Make the Ca/S ratio in the bed increase, thereby improve the utilization rate and the desulfuration efficiency of desulfurizing agent, reduced production cost.The utility model also has the enforcement characteristic of simple structure.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Being labeled as in the accompanying drawing: 1-desulfurizing tower, 2-baffle liner, 3-deflector.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described, but not as the foundation to the utility model restriction.
Embodiment.A kind of circulating fluid bed semi-drying method desulfurizing tower strong inverse flow device constitutes as shown in Figure 1ly, comprises desulfurizing tower 1, and characteristics are: described desulfurizing tower 1 inner top is provided with the baffle liner 2 that is surrounded by some deflectors 3.
Described deflector 3 becomes 10～14 ° of settings with the outer wall of desulfurizing tower 1.
The utility model is provided with the baffle liner that is formed a circle by some deflectors through the top in desulfurizing tower; Make flue gas rise to the strong inverse flow of back formation here; Strengthened further that tower is endocorpuscular to be returned, improved the endocorpuscular bed density of tower, made that the Ca/S ratio in the bed increases; Thereby improve the utilization rate and the desulfuration efficiency of desulfurizing agent, reduced production cost.The utility model also has the enforcement characteristic of simple structure.
Claims (2)
1. a circulating fluid bed semi-drying method desulfurizing tower strong inverse flow device comprises desulfurizing tower (1), it is characterized in that: described desulfurizing tower (1) inner top is provided with the baffle liner (2) that is surrounded by some deflectors (3).
2. circulating fluid bed semi-drying method desulfurizing tower strong inverse flow device according to claim 1 is characterized in that: described deflector (3) becomes 10～14 ° of settings with the outer wall of desulfurizing tower (1).
