Problems solved by technology

[0005] The purpose of the present invention is to provide a flow guide fin that enhances the internal circulation of the flue gas purification reaction tower, which can solve the problem that the existing flue gas purification reaction tower cannot form a stable and efficient internal circulation due to the lack of appropriate measures to guide the flow of ash on the wall. As a result, the realization of the desulfurization process is seriously affected, and due to the high-concentration wall backflow without proper flow stabilization measures, premature diffusion into the mainstream area affects the mixing effect of the desulfurization process

specific Embodiment approach 1

[0009] Specific Embodiment 1: This embodiment is described in conjunction with Fig. 1 and Fig. 2. In this embodiment, the tower top ribs 2 fixed on the top end surface 4 in the tower top 1 and the fins evenly distributed on the inner side wall 8 of the tower top 1 The side wall fins 3 are composed; the tower top fins 2 are a group of bent fins 6 with openings facing the opposite side of the airflow outlet 5 and gradually expanding along the direction of the airflow outlet 5. The tower top 1 The cross section is a combination of rectangle and semicircle, the distance h1 between the lower end surface of the tower top fin 2 and the top end surface 4 inside the tower top 1 is 20-200 mm, and the outer surface of the side wall fin 3 The distance h2 between the end surface and the inner wall 8 of the tower top 1 is 20-200 mm, and the tower top fins 2 and side wall fins 3 are made of metal materials or cast concrete. Such setting can enhance the flow guiding effect of the fins.

specific Embodiment approach 2

[0010] Specific embodiment 2: This embodiment is described in conjunction with Fig. 3 and Fig. 4 , the difference between this embodiment and specific embodiment 1 is: the tower top fins 2 of this embodiment are a group of openings facing the opposite side of the airflow outlet 5 , and the curved fins 7 gradually expand along the direction of the airflow outlet 5 . Such setting can enhance the flow guiding effect of the fins.

specific Embodiment approach 3

[0011] Specific embodiment 3: This embodiment is described in conjunction with Fig. 5 and Fig. 6. The difference between this embodiment and specific embodiments 1 and 2 is that the tower top fins 2 of this embodiment are a group along the top of the tower top 1 The straight ribs 9 uniformly distributed laterally on the surface 4. Such setting can enhance the flow guiding effect of the fins.

Abstract

The present invention relates to a kind of flow-guiding fin capable of enhacing interior circulation of flue gas cleaning reaction tower, belonging to a flue gas pollution cleaning equipment. Said invention includes tower top fins which are fixed on the top end surface of tower top interior and side-wall fins which are uniformly distributed on the side wall of tower top interior. Said invention also provides the concrete structure of every kind of fins.

Description

technical field [0001] The invention relates to a flue gas pollution purification device in the field of environmental protection and chemical industry, in particular to a diversion fin for enhancing the internal circulation of a reaction tower. Background technique [0002] Reaction tower equipment using circulating fluidization technology is widely used in chemical industry, energy, environmental protection and other fields. Specific to the semi-dry flue gas circulating fluidized bed desulfurization technology, the high rate circulation effect is the key to obtain high desulfurization efficiency and high absorbent utilization efficiency. In the past, most technologies relied on adding external separation equipment to strengthen the desulfurization ash circulation in the tower. In order to improve system economy, simplify equipment and facilitate maintenance, it is hoped that the circulation effect in the reaction tower can be enhanced. [0003] In a circulating fluidized...
