Embodiment Construction

[0018] see Figure 1-3 , this kind of flue gas wet desulfurization square absorption tower, the lower part of the tower body is the circulating slurry pool 2, the upper part of the tower body is the washing reaction tower 1, the cross-sections of the upper part and the lower part of the tower body are rectangular, and they are vertically connected as one. The lower part communicates with the smoke inlet pipe 3, and the middle part of the upper section is equipped with four layers of spray pipes 4. The spray pipe includes a main pipe 9 and branch pipes 10 branched from both sides of the main pipe. There are inspection holes 13 and exhaust holes 14 on the main pipe 9. 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 above-mentioned tower body is made o...

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 in the flue gas, a reaction tower for flue gas reaction must be built, and the flue gas must be sent to the reaction tower through the flue for desulfurization reaction. Usually the reaction tower is round in steel, requiring special prefabrication and complex on-site assembly. The device is in the shape of a two-section variable-diameter vertical tower, the lower section is a gypsum slurry pool, the upper section is a desulfurization reaction section, and the lower part of the desulfurization reaction section is connected with the smoke inlet pipe. The design of the tower is complex, the processing, welding and installation of the cylindrical tower body are difficult, the flow field distribution and flow velocity of the flue gas in the reaction tower are unreasonable, and the slu...
