Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a desulfurization wastewater treatment device. Background Technology

[0002] In industries such as power, chemical, and metallurgy, the use of coal or sulfur-containing raw materials generates a large amount of sulfur-containing flue gas. To control sulfur dioxide emissions, enterprises generally adopt wet desulfurization processes. Although this process can effectively remove sulfur from flue gas, it also generates desulfurization wastewater with complex composition. This wastewater not only contains high concentrations of suspended solids and heavy metal ions (such as mercury, lead, and cadmium), but also contains large particulate solid impurities (such as calcium carbonate fragments and unreacted desulfurizing agent particles) formed by the wear and tear of desulfurizing agents and the shedding of raw material impurities. If directly discharged or without effective treatment, it will cause serious pollution to water bodies and soil ecosystems. Therefore, it must be purified to meet standards through professional treatment equipment before being discharged. In actual operation, large particulate impurities (usually with a particle size of 0.5 mm or more) in desulfurization wastewater enter the treatment tank directly with the wastewater. On the one hand, they will settle at the bottom of the tank, causing blockage of the outlet, requiring frequent shutdowns for cleaning, increasing equipment maintenance costs and replacement frequency. On the other hand, they will mix with flocs, causing the sludge moisture content to increase, making subsequent sludge dewatering treatment more difficult and inconvenient. Furthermore, the flocculant in the tank is directly injected into the treatment tank, and the mixing with the wastewater is insufficient, which can easily affect the flocculation effect. Therefore, this application provides a desulfurization wastewater treatment device to meet the requirements. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a desulfurization wastewater treatment device that can prevent large particulate impurities in the wastewater from affecting the wastewater treatment and avoid the technical problem of poor wastewater treatment effect caused by uneven mixing of flocculant and wastewater.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A desulfurization wastewater treatment device includes a treatment tank; Flocculant tube, which is fixedly connected to one side of the treatment tank; The water outlet pipe is fixedly connected to one side of the treatment tank; Waste outlet, which is located at the bottom of the treatment tank; A filter assembly is disposed at the top of the processing tank. The filter assembly includes a U-shaped plate, an annular plate is fixedly connected to the bottom of the U-shaped plate, and a filter disc is fixedly connected to the inner surface of the annular plate. A stirring assembly is disposed between a U-shaped plate and a filter circular plate. The stirring assembly includes a transmission rod, which is rotatably disposed on the inner wall of the filter circular plate. A stirring rod is fixedly connected to the bottom end of the transmission rod. A discharge assembly is disposed on one side of the processing tank.

[0005] The filter components can filter out large particles of impurities in the wastewater, preventing them from affecting the pipelines and flocculation in subsequent treatment processes. The mixing components allow the flocculant to mix thoroughly with the wastewater, thus facilitating flocculation.

[0006] Optionally, an annular locking block is fixedly connected to the bottom of the annular plate, and an annular locking frame is fixedly connected to the inner wall of the processing tank, with the annular locking block and the annular locking frame engaging and fitting together.

[0007] The annular locking block can engage with the annular locking frame, allowing the annular plate to be connected to the processing tank.

[0008] Optionally, L-shaped plates are symmetrically fixedly connected to both sides of the U-shaped plate, a first screw hole is opened on one side of the L-shaped plate, a rectangular block is fixedly connected to one side of the processing tank, a second screw hole is opened on one side of the rectangular block, and threaded clamps are threadedly connected to the inner walls of the first screw hole and the second screw hole.

[0009] The threaded clamp can be fixed with the first and second threaded holes, thereby fixing the L-shaped plate to the treatment tank, and allowing components such as the filter disc to be fixed to the treatment tank.

[0010] Optionally, a drive motor is installed on the top of the U-shaped plate, and the output end of the drive motor is fixedly connected to the top end of the transmission rod.

[0011] The drive motor can drive the transmission rod to rotate, and can provide driving force for the rotation of the transmission rod.

[0012] Optionally, a connecting block is fixedly connected to the outer surface of the transmission rod at the top of the filter disc, and a brush plate is fixedly connected to the outer surface of the connecting block.

[0013] The brush plate can clean large particles from the top of the filter disc, preventing them from staying in a fixed position on the filter disc and causing blockage.

[0014] Optionally, the discharge assembly includes a discharge port located on one side of the processing tank. A U-shaped mounting plate is fixedly connected to one side of the processing tank. A U-shaped groove is provided on the top of the U-shaped mounting plate. A U-shaped locking block is engaged with the inner wall of the U-shaped groove. A baffle is fixedly connected to the inner surface of the U-shaped locking block.

[0015] The U-shaped clamp can be engaged with the U-shaped channel, thereby allowing the installation of a baffle and sealing of the discharge port.

[0016] Optionally, a U-shaped block is fixedly connected to the top of the outer surface of the baffle, and sliding rods are slidably connected to both sides of the U-shaped block. An operating block is fixedly connected to one end of the sliding rod, and a positive magnet is fixedly connected to the other end of the sliding rod. Negative magnets are fixedly connected to both sides of the U-shaped mounting plate.

[0017] The magnetic fixation between the positive and negative magnets makes the installation of the baffle and the U-shaped mounting plate more secure.

[0018] Compared with the prior art, this utility model has at least the following beneficial effects: By setting up a filtration component, large particulate impurities inside the wastewater can be filtered out, preventing them from clogging pipes and other components in subsequent treatment processes, thereby reducing the cost of subsequent cleaning and maintenance. At the same time, the agitation component can mix the flocculant and wastewater evenly, resulting in better flocculation.

[0019] By setting up a discharge assembly, large particles of impurities filtered through the filter disc can be removed. This requires the use of external cleaning tools to sweep these large particles away from the filter disc and allow them to exit through the discharge port.
