Description

Technical Field

[0001] The utility model relates to the field of thermal power plants, in particular to a wastewater cyclone device of a desulfurization device in a thermal power plant. Background Art

[0002] As we all know, in the flue gas desulfurization process of thermal power plants, the gypsum slurry in the desulfurization device will be enriched with impurities such as heavy metal elements, fine dust and chloride ions during the continuous circulation process. These impurities will accelerate the corrosion of the desulfurization device on the one hand, and affect the quality of the gypsum on the other hand. At the same time, it will also affect the desulfurization efficiency of the desulfurization device. Therefore, the desulfurization device needs to discharge a certain amount of wastewater to reduce the content of these impurities in the gypsum slurry. After discharging the wastewater, the desulfurization wastewater flows into the neutralization tank. Lime milk needs to be added to the neutralization tank to adjust the pH value of the wastewater and convert the fluoride ions in the water into insoluble calcium fluoride precipitation, so that most of the heavy metal ions in the wastewater are precipitated in the form of slightly soluble hydroxides. However, in the actual operation process, the lime milk is prone to hardening in the transmission pipeline, resulting in pipeline blockage, and it needs to be cleaned to avoid affecting the normal operation of the equipment.

[0003] After searching, the utility model patent with Chinese publication number CN210647592U discloses a wastewater cyclone system of a desulfurization device in a thermal power plant, which includes a neutralization box and a dosing pipeline, a dosing port is detachably connected to a shell, a positioning mechanism is connected to the outer wall of the shell, an electric telescopic rod is rotatably connected in the shell, a rotating plate is connected to the top of the electric telescopic rod, a rotating rod is connected to the outer wall of the rotating plate, an end of the electric telescopic rod away from the rotating plate passes through the shell and is connected to a fixed block, small telescopic rods are connected to the outer walls of both sides of the fixed block, a straight plate is connected to the end of the small telescopic rod away from the fixed block, a first elastic element is sleeved on the outer wall of the small telescopic rod, the first elastic element is connected between the fixed block and the straight plate, and a brush is connected to the outer wall of the straight plate; the utility model uses a brush to clean the dosing pipeline to avoid the lime milk gathered in the dosing pipeline from clogging the pipeline, thereby ensuring the normal operation of the equipment.

[0004] Although the above technical solution solves the blockage problem in the dosing pipeline, in the above technical solution, if the lime milk solidifies, it will cause blockage of the pipeline, and the solidified lime milk will have a great impact on the pipeline. The above solution only uses a brush to clean the pipeline, and it is impossible to fully clean the solidified lime milk in the pipeline. Therefore, a wastewater cyclone device for a desulfurization device in a thermal power plant is needed. Utility Model Content
