Embodiment Construction

[0011] As shown in the accompanying drawings, a dry-process desulfurization absorption tower with a top circular elbow outlet of the present invention is connected with a variable diameter section 2 for adjusting the flow velocity at the top of the absorption tower main body section 1 (circular straight pipe section). An outlet flue 3 is installed above the diameter section 2, and the outlet flue 3 is in the shape of a 180-degree slow-rotating shrimp elbow, and is connected with the radius segment 4. An adjustment segment 5 is arranged below the radius segment 4, and the adjustment segment 5 is connected to the radius segment 4. The inlet connection of dust collector 7. The outlet flue 3 does not use a square flue but a circular flue. The circular flue has the advantages of good self-supporting force, large spacing between the required external reinforcement ribs, and small size, which can effectively reduce the steel material of the absorption tower outlet flue body. At the s...

Abstract

The invention discloses a dry method desulphurization absorption tower with a top round bent pipe outlet. In order to solve the problems that the square outlet of the prior dry method desulphurization absorption tower has overlarge local resistance, inordinate flue gas flow field, easy generation of solid particle accumulation on a local part and the like. The upper part of a main body section (1) of the absorption tower is connected with a reducing section (2); the upside of the reducing section (2) is provided with an outlet flue (3) which adopts a round bent pipe flue and is connected with a round square section (4); and the underside of the round square section (4) is provided with an adjusting section (5) which is connected with the inlet of a dust collector (7). The design of the absorption tower not only greatly reduces the local resistance of the outlet, optimizes the flue gas flow field and reduces the local solid particle accumulation, but also can remarkably reduce the construction cost; besides, the absorption tower has the advantages of simple manufacture, convenient maintenance, long service life and the like.

Description

technical field [0001] The invention relates to an absorption tower, in particular to a dry desulfurization absorption tower with a top circular elbow outlet, which is suitable for the dry desulfurization process of flue gas in power plants. Background technique [0002] At present, in the dry flue gas desulfurization technology, the outlet flue of the absorption tower has always been made into an integrated device with the absorption tower. Such a dry desulfurization absorption tower is disclosed on the market. Its structural characteristics are: above the desulfurization absorption tower A straight pipe section is provided, and there is an opening on the side of the top of the straight pipe section, and it is connected to the dust collector through a square connecting section, so that the flue gas is connected horizontally from the top side outlet of the straight pipe section of the desulfurization absorption tower, through the side square connecting section horn, and then...
