Embodiment Construction

[0026] In order to make the technical means, creative features, objectives and effects of the invention easy to understand, the present invention will be further described below in conjunction with the accompanying drawings.

[0027] A kind of desulfurization wastewater treatment system of the present invention, as figure 1 As shown, the desulfurization wastewater treatment system includes a decontamination and softening device, an atomization drying device, and a central intelligent controller device. connect. The central intelligent controller device is composed of a PLC controller, which is connected and controlled with the decontamination softening device and the atomization drying device respectively, so that the whole system can run continuously and automatically from the waste water entering the system to the packing treatment of solid salt. , thereby reducing the input of manpower control costs.

[0028] The decontamination and softening device includes an electronic...

Abstract

The invention relates to the field of environmentally friendly water treatment, and discloses a desulfurization wastewater treatment system. The system includes a decontamination and softening deviceand an atomizing and drying device; the front end of the decontamination and softening device is connected to an external desulfurization absorption tower, and the tail end of the decontamination andsoftening device is connected to the atomizing and drying device; the decontamination and softening device includes an electronic flocculation mechanism, a filter mechanism, a water quality softeningmechanism and a sludge treatment mechanism; and the atomizing and drying device includes a reservoir mechanism, an atomizer mechanism and a drying mechanism. Treatment can be performed by directly connecting the decontamination and softening device and the atomizing and drying device, and additives and sludge amounts can be reduced and energy saving and consumption reduction can be realized by arranging the electronic flocculation mechanism, so that the problems in the prior art of secondary pollution caused by adding a flocculating agent in a triple box dosing and sedimentation process and production efficacy loss brought during transferring can be solved.

Description

technical field [0001] The invention relates to the field of environmental protection water treatment, in particular to a desulfurization wastewater treatment system. Background technique [0002] In the environmental protection water treatment industry, the impurities of commonly used limestone wet desulfurization wastewater mainly come from flue gas and desulfurizers, wherein the impurities of flue gas come from the combustion of coal, and the impurities of desulfurizers come from the dissolution of limestone (currently Limestone is mostly used); since coal may contain various elements including heavy metal elements, such as F, Cl, Cd, Pb, Ni, As, Se, Cr, etc. A chemical reaction produces many different compounds. Part of the compound is discharged from the furnace with the slag, and the other part enters the absorption tower of the desulfurization device with the flue gas and is dissolved in the absorption slurry. To improve the quality of gypsum, a certain amount of ...
