Technical Field

[0001] The utility model relates to the technical field of flue gas desulfurization wastewater treatment equipment, in particular to a flocculation tank structure for desulfurization wastewater treatment. Background Art

[0002] Wet desulfurization is one of the common methods of flue gas desulfurization treatment. Flue gas desulfurization is carried out by spraying flue gas with desulfurization slurry. After the desulfurization slurry is sprayed on the flue gas, desulfurization wastewater will be formed. The desulfurization wastewater cannot be discharged directly, and needs to go through neutralization, sedimentation, flocculation, concentration and other steps; among them, the flocculation treatment step includes placing the settled wastewater in a flocculation tank, and then adding flocculants to aggregate and precipitate the suspended matter in the wastewater to achieve the purpose of removing the suspended matter. However, the conventional flocculation tank only includes a tank body structure, a dosing device is arranged above the tank body structure, and a stirring structure is arranged in the tank body. The above-mentioned flocculation tank structure has low adjustability during the wastewater flocculation operation, and the flocculation may be easily broken and the flocculation effect is poor.

A fixed frame is provided above the flocculation tank body, and a driving structure is arranged on the fixed frame. The driving structure is connected to a stirring structure, and the stirring structure extends into the flocculation tank body. The driving structure is slidably connected to the fixed frame. A water outlet is provided on one side wall of the flocculation tank body and a fixed plate connected to the side wall. There are two groups of water outlets, which are arranged in the middle and the upper part. A second water outlet is provided at the bottom of the flocculation tank body, and an aeration structure is also provided at the bottom of the flocculation tank body.

[0006] The utility model discloses a flocculation tank structure for treating desulfurized wastewater, and the further improvement lies in that a filter screen is arranged at the water outlet of the fixed plate, and the filter screen is hemispherical.

[0007] The utility model further improves the flocculation tank structure for desulfurization wastewater treatment in that the driving structure includes a motor, a sliding plate is slidably connected to the fixed frame, the motor is arranged on the sliding plate, the sliding plate is also rotatably connected to a stirring shaft, the stirring shaft and the motor are connected by a transmission structure, and the upper end of the stirring shaft passes through the sliding plate.

[0008] The utility model provides a further improvement on the flocculation tank structure for desulfurization wastewater treatment in that the stirring shaft is hollow, a fixing hole is arranged at the lower part of the stirring shaft, a dosing structure is also arranged on the sliding plate, and the dosing structure comprises a dosing pipe extending into the upper part of the stirring shaft.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] The utility model realizes the adjustment of desulfurization wastewater flocculation by adjusting the rotation speed of the mobile stirring structure and the stirring structure itself, thereby ensuring the flocculation effect; at the same time, the side wall of the fixed plate is designed to be wavy to improve the turbulence effect and thus improve the flocculation effect; on the other hand, the fixed plate is detachable and can also be disassembled and cleaned regularly to ensure the service life of the flocculation tank.

A second water outlet is provided at the bottom of the flocculation tank body, and an aeration structure 9 is also provided at the bottom of the flocculation tank body. The provision of two groups of water outlets facilitates the graded discharge of wastewater after flocculation sedimentation.

[0015] A filter screen 8 is provided at the water outlet on the fixed plate, and the filter screen is preferably hemispherical, so as to reduce the possibility of flocculants directly blocking the water outlet.
