Embodiment Construction

[0018] See Figure 1-3 , This kind of flue gas wet desulfurization square absorption tower, the lower section of the tower body is the circulating slurry tank 2, the upper section of the tower body is the washing reaction tower 1, the upper and lower sections of the tower are rectangular in cross section, and they are vertically connected as a whole. The lower part is connected with the smoke inlet pipe 3, and the middle part of the upper part is equipped with four layers of spray pipes 4, the spray pipe includes a main pipe 9 and branch pipes 10 separated from both sides of the main pipe. The main pipe 9 has an inspection hole 13 and an exhaust hole 14. The main pipe 9 and the branch pipe 10 are connected by a flange 12, and the two ends of the branch pipe are erected on the support 11 on the wall of the absorption tower.

[0019] The tangential direction at the top of the tower body is connected to the flue gas outlet 5. The material of the tower body is steel or concrete structu...

Abstract

The invention relates to a smoke wet sulfur trioxide square adsorption tower. Wherein, the lower section of tower is a cycle slurry tank and the upper section is a washing reaction section; the sections of upper and lower sections are both rectangle and vertically connected; the lower part of upper section is connected to the smoke inlet tube; the middle part of upper section is mounted with spray tubes; the tangent part of top of tower is connected to the smoke outlet; a mixer and a vent tube are inserted into the lower cycle slurry tank. The invention can avoid the slurry deposition of slurry to improve the efficiency of desulfuration and apply the installment of said adsorption tower.

Description

(1) Technical field [0001] The invention relates to a flue gas wet desulfurization device. (2) Background technology [0002] In the existing wet desulfurization process, in order to remove sulfur from the flue gas, a reaction tower for the flue gas reaction must be built, and the flue gas must be sent to the reaction tower through the flue for desulfurization reaction. The usual reaction tower is round steel, requiring special pre-processing and complex on-site assembly. The device is a two-section variable-diameter vertical tower, the lower section is a gypsum slurry tank, the upper section is a desulfurization reaction section, and the lower part of the desulfurization reaction section is connected with the flue gas inlet pipe. The tower shape design is complex, the cylindrical tower body is difficult to process, weld and install, the flow field distribution and flow rate of the flue gas in the reaction tower are unreasonable, and the slurry in the bottom slurry pool of the re...
