The utility model relates to a kind of absorption tower, and particularly a kind of absorption tower with modular shoe, belongs to field of Environment Protection.
Background technology
Absorption tower is used for means of flue gas desulfurization of power plant, denitration, is the requisite equipment of power plant.Absorb slurries during work to spray from top to bottom, flue gas flows from the bottom up in absorption tower, and the nozzle of spraying layer outmost turns easily washes away Ta Bi, causes tower wall to wear and tear: when adopting unidirectional nozzle, and nozzle mainly washes away the tower wall of its close beneath; When adopting Bidirectional nozzle, nozzle mainly washes away above spraying layer, the tower wall of close beneath.Absorb slurries and wash away Ta Bi for a long time, continuously, easily cause tower wall to wear and tear, be unfavorable for device security stable operation.
After flue gas enters absorption tower, flow from the bottom up, but due to smoke inlet flow velocity comparatively large, the Field Characteristics formed in tower: the flue gas flow rate at tower center is lower, the flue gas flow rate of limit wall is excessive.This easily causes: the Pressure Loss Ratio at wall place, limit is larger on the one hand; On the other hand because sparger arrangement structure makes slurries near tower wall not have the concentration of slurry at tower center high, thus be unfavorable for removing of bad air in flue gas.
Utility model content
The purpose of this utility model is to provide a kind of absorption tower with modular shoe, and it effectively can prevent absorption tower inner body wall wearing and tearing, can carry out water conservancy diversion to flue gas simultaneously, makes flue gas to the flowing of spray compact district, reduces the crushing at wall place, limit.
The technical solution of the utility model: a kind of absorption tower with modular shoe, comprise absorption tower body, demist layer, spraying layer and slurry pool, slurry pool is located at intrinsic bottom, absorption tower, demist layer is located at intrinsic top, absorption tower, the below of demist layer is provided with the spraying layer of more than 2 layers, the below of described every layer of spraying layer is equipped with wearing ring, wearing ring is combined by anti-abrasion body, the inwall of absorption tower body is provided with hook, and anti-abrasion body is fixed on the inwall of absorption tower body by hook.
Aforesaid have in the absorption tower of modular shoe, and the distance between described every layer of spraying layer and the anti-abrasion body below it is 0.7m ~ 1m.
Aforesaid have in the absorption tower of modular shoe, and the distance between described every layer of spraying layer and the anti-abrasion body below it is 0.8m.
Aforesaid have in the absorption tower of modular shoe, and the section configuration of described anti-abrasion body is triangle or trapezoidal.
Aforesaid have in the absorption tower of modular shoe, and anti-abrasion body is hollow-core construction.
Aforesaid have in the absorption tower of modular shoe, is filled with resin in the gap between the inwall of anti-abrasion body and absorption tower body.
Compared with prior art, the utility model adopts modularized design, and form a wearing ring by multiple anti-abrasion body, the absorption slurries that not only can effectively prevent outmost turns nozzle from spraying wash away Ta Bi; Simultaneously the flue gas of guide properly absorption tower surrounding can enter tower central area, reduce pressure drop.
Adopt modularized design to be convenient to processing and manufacturing, on-the-spot convenient installation, and maximum advantage to change separately the more serious anti-abrasion body of certain wearing and tearing, without the need to integral replacing, reduces maintenance and replacement cost.Owing to adopting the connected mode of coupling type, give maintenance, more to change jobs the facility also brought.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described.
Embodiment 1 of the present utility model: as depicted in figs. 1 and 2, a kind of absorption tower with modular shoe, comprise absorption tower body 1, demist layer 2, spraying layer 3 and slurry pool 4, slurry pool 4 is located at the bottom in absorption tower body 1, demist layer 2 is located at the top in absorption tower body 1, the below of demist layer 2 is provided with the spraying layer 3 of more than 2 layers, the below of described every layer of spraying layer 3 is equipped with wearing ring 5, wearing ring 5 is combined by anti-abrasion body 6, the inwall of absorption tower body 1 is provided with hook 7, and anti-abrasion body 6 is fixed on the inwall of absorption tower body 1 by hook 7.Distance between every layer of spraying layer 3 and the anti-abrasion body below it 6 is 0.7m.The section configuration of described anti-abrasion body 6 is triangle.Anti-abrasion body 6 is hollow-core construction.Resin 8 is filled with in gap between the inwall of anti-abrasion body 6 and absorption tower body 1.
Embodiment 2 of the present utility model: a kind of absorption tower with modular shoe, comprise absorption tower body 1, demist layer 2, spraying layer 3 and slurry pool 4, slurry pool 4 is located at the bottom in absorption tower body 1, demist layer 2 is located at the top in absorption tower body 1, the below of demist layer 2 is provided with the spraying layer 3 of more than 2 layers, the below of described every layer of spraying layer 3 is equipped with wearing ring 5, wearing ring 5 is combined by anti-abrasion body 6, the inwall of absorption tower body 1 is provided with hook 7, and anti-abrasion body 6 is fixed on the inwall of absorption tower body 1 by hook 7.Distance between every layer of spraying layer 3 and the anti-abrasion body below it 6 is 0.8m.The section configuration of described anti-abrasion body 6 is trapezoidal.Anti-abrasion body 6 is hollow-core construction.Resin 8 is filled with in gap between the inwall of anti-abrasion body 6 and absorption tower body 1.
