This invention removes different impurities from wastewater in stages, reducing impurities in the final product, and the batch removal of impurities facilitates further processing.

[0003] In the aforementioned technologies, the concentrated water produced by the pretreatment membrane system after the leachate passes through the water treatment process still contains a high content of pollutants, necessitating treatment of the leachate to reduce secondary pollution to the water treatment process. Utility Model Content

[0004] To address the issue that the concentrated water produced by the pretreatment membrane system in the current water treatment process still contains a high content of pollutants, and that it is necessary to treat the permeate to reduce secondary pollution to the water treatment process, this application provides an efficient drying device for evaporation mother liquor.

The air inlet pipe is externally connected to a steam generator, and the liquid inlet pipe is connected to a permeate discharge port.

[0006] By adopting the above technical solution, the inlet pipe introduces the permeate into the permeate spraying unit, which sprays the permeate evenly onto the outer surface of the drum. The air inlet pipe introduces high-temperature steam into the inner wall of the drum. During continuous operation, a thin layer of permeate is continuously spread on the surface of the drum. When the permeate comes into contact with the drum surface filled with steam from the inside, it exchanges heat and vaporizes. The moisture is converted into steam and discharged through the exhaust port, while the remaining pollutants are converted into solid mud and salt, which adhere to the drum surface. The solid mud and salt are scraped off by the mud scraping unit and fall to the discharge port below, where they are then bagged and sealed to achieve the drying effect.

[0017] Optionally, the sludge scraping unit includes a lead screw disposed inside the drying chamber, a movable seat connected to the lead screw via a threaded structure, a scraper connected to the movable seat, and a second drive motor for driving the lead screw. The two ends of the lead screw are respectively connected to the two ends of the inner wall of the drying chamber via bearing seats.

In this model, the inlet pipe 31 introduces the permeate into the permeate spraying unit, which sprays the permeate evenly onto the outer surface of the drum 2. The air inlet pipe 4 introduces high-temperature steam into the inner wall of the drum 2. During continuous operation, a thin layer of permeate is continuously spread on the surface of the drum 2. When the permeate comes into contact with the surface of the drum 2, which is filled with steam from the inside, it exchanges heat and vaporizes. The moisture is converted into steam and discharged through the exhaust port, while the remaining pollutants are converted into solid mud and salt, which adhere to the surface of the drum 2. The solid mud and salt are scraped off by the mud scraping unit and fall into the discharge port 11 below, where they are then bagged and sealed to achieve the drying effect.

During continuous operation, a thin layer of permeate is continuously spread on the surface of the drum 2, and the air inlet pipe 4 introduces high-temperature steam into the inner cavity of the drum 2. When the permeate comes into contact with the surface of the drum 2, which is filled with steam from the inside, it exchanges heat and vaporizes. The water is converted into steam and discharged through the exhaust port, while the remaining pollutants are converted into solid mud and salt, which adhere to the surface of the drum 2. The output shaft of the second servo motor facilitates the rotation of the lead screw 71. When the lead screw 71 rotates, it drives the moving seat 72 to move horizontally around the lead screw 71 as the central axis, thereby facilitating the horizontal movement of the scraper 6 on the outer periphery of the drum 2 to scrape off the solidified mud and salt on the outer periphery of the drum 2.
