Desulfurization wastewater pretreatment reaction device

Abstract

The invention discloses a desulfurization wastewater pretreatment reaction device, which comprises a base and a threaded hole, a shell is arranged at the upper end of the base, a supporting plate is arranged at the upper end of the interior of the shell, a motor is arranged on the right side of the upper end of the supporting plate, a rotating rod is arranged in the middle of the lower end of themotor, and a gear is arranged on the outer ring of the middle of the rotating rod; a conveyor belt is arranged outside the gear; driven rods are arranged at the left end and the right end of the rotating rod, stirring blades are arranged on the two sides of the lower ends of the driven rods, a reaction tank is arranged outside the stirring blades, a transverse plate is arranged in the reaction tank, and an internal water outlet is formed in the middle of the lower end of the transverse plate; and a filter screen is arranged at the lower end of the internal water outlet. The desulfurization wastewater pretreatment reaction device is provided with a connecting plate, and the connecting plate performs lifting motion at the lower end of the supporting plate under the action of a hydraulic pushrod, so that a user can conveniently control the position of the connecting plate through the hydraulic push rod, and a brush at the lower end of the connecting plate is controlled.

Description

technical field [0001] The invention relates to the technical field of desulfurization wastewater, in particular to a desulfurization wastewater pretreatment reaction device. Background technique [0002] Desulfurization wastewater is mainly the discharge water from the absorption tower during the wet desulfurization process of boiler flue gas. In order to maintain the balance of substances in the slurry circulation system of the desulfurization device, prevent the soluble part in the flue gas, that is, the chlorine concentration from exceeding the specified value, and ensure the quality of gypsum, it must be drained from the system. A certain amount of waste water is discharged in the plant, and the waste water mainly comes from the gypsum dehydration and cleaning system. [0003] During the use of desulfurization wastewater on the market, there will be a large amount of sludge in the internal pretreatment reaction device. If it is not cleaned for a long time, it will easil...
