Description

Technical Field

[0001] This utility model relates to the field of sintering wastewater purification technology, specifically a multifunctional reactor for treating sintering wastewater using sulfide nano-zero valent iron. Background Technology

[0002] Sintering wastewater mainly comes from four sources: drainage from wet dust removal systems, equipment flushing water, desulfurization wastewater, and cooling system drainage. It contains pollutants such as suspended solids, heavy metals, and salts. When purifying sintering wastewater, it is necessary to treat the pollutants in the wastewater using sulfide nano-zero valent iron.

[0003] Existing equipment cannot effectively recover sulfide nano-zero valent iron. After the reaction, the sulfide nano-zero valent iron combines with heavy metal pollutants and mixes with other solid substances and pollutants, making effective separation impossible. This may cause secondary pollution after discharge. Therefore, a multifunctional reactor for treating sintering wastewater with sulfide nano-zero valent iron is proposed. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a multifunctional reactor for treating sintering wastewater using sulfidated nano-zero valent iron, in order to solve the technical problems mentioned in the background above.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multifunctional reactor for treating sintering wastewater using sulfide nano-zero valent iron, comprising a tank, an inlet pipe connected to the top of the tank, a feed trough connected to the side of the top of the tank away from the inlet pipe, an electromagnet fixedly connected to the top of the inner wall of the tank, the electromagnet being ring-shaped, a filter press connected to the bottom of the tank, and the connection between the tank and the filter press being conical.

[0006] As a preferred technical solution, a motor is fixedly connected to the top of the tank, the motor is located between the water inlet pipe and the feed trough, and a rotating shaft is fixedly connected to the output end of the motor, the rotating shaft extending into the inside of the tank.

[0007] As a preferred technical solution, two sets of crossbeams are fixedly connected to the outer wall of the rotating shaft, and two sets of stirring cages are rotatably connected between the two sets of crossbeams, with the two sets of stirring cages located at both ends of the crossbeams.

[0008] As a preferred technical solution, two sets of gearboxes are fixedly connected to the top of the upper set of crossbeams. The output end of each set of gearboxes is fixedly connected to the top of a set of stirring cages. A set of rollers is fixedly connected to the input end of each set of gearboxes. A pressure ring is fixedly connected to the inner wall of the tank, and the bottom end of the pressure ring abuts against the outer wall of the rollers.

[0009] As a preferred technical solution, a fixing ring is fixedly connected to the outer wall of the tank, and at least four sets of support legs are fixedly connected to the side wall of the fixing ring. A set of support blocks is slidably sleeved on the inner wall of each set of support legs. A stud is rotatably connected to the inner wall of the support block. The stud is threadedly connected to the inner wall of the support leg, and the top of the stud extends to the outside of the support leg.

[0010] In summary, the present invention has the following main advantages: 1. This utility model involves adding nano-zero ferric sulfide to sintering wastewater for reaction, using an intelligent program to control the amount of nano-zero ferric sulfide added, and when the reaction time is sufficient, using an electromagnet to adsorb the nano-zero ferric sulfide, and then filtering the treated wastewater through a filter press to discharge it, thereby separating the nano-zero ferric sulfide from the wastewater and other impurities, and avoiding secondary pollution of the wastewater. 2. This utility model utilizes a motor to drive a rotating shaft during the reaction process, causing two sets of stirring cages to rotate around the shaft and rotate on their own axis. This fully mixes the wastewater and sulfide nano-zero ferric iron, improving reaction efficiency and significantly increasing the wastewater treatment speed. Furthermore, the stirring method of rotating on its own axis and revolving around the shaft avoids the formation of a mixing dead zone between the wastewater and sulfide nano-zero ferric iron inside the tank during the reaction process.

[0013] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0014] The embodiments of this utility model will be described below based on its overall structure.

[0015] A multifunctional reactor for treating sintering wastewater using sulfidated nano-zero valent iron, such as... Figures 1 to 4 As shown, the device includes a tank body 1, with a water inlet pipe 2 connected to the top of the tank body 1. A feed trough 3 is connected to the side of the top of the tank body 1 away from the water inlet pipe 2. An electromagnet 4, which is ring-shaped, is fixedly connected to the top of the inner wall of the tank body 1. A filter press 5 is connected to the bottom of the tank body 1. The connection between the tank body 1 and the filter press 5 is conical. A fixing ring 6 is fixedly connected to the outer wall of the tank body 1. At least four sets of support legs 7 are fixedly connected to the side wall of the fixing ring 6. A set of support blocks 8 are slidably fitted on the inner wall of each set of support legs 7. A stud 9 is rotatably connected to the inner wall of the support block 8. The stud 9 is threaded to the inner wall of the support leg 7, and the top of the stud 9 extends to the outside of the support leg 7.

[0016] Sintering wastewater is added to tank 1 through inlet pipe 2. Addition stops once a specified amount of sintering wastewater has been added. Then, sulfide nano-zero-valent iron powder is added to tank 1 through feed trough 3. The amount of sulfide nano-zero-valent iron added can be precisely controlled using an existing electronic control system. After the sintering wastewater and sulfide nano-zero-valent iron have fully reacted, the sulfide nano-zero-valent iron is adsorbed using electromagnet 4. The sintering wastewater then passes through filter press 5 to filter out solid impurities. The treated water is then discharged, and the filtered impurities are removed. Impurities are discharged through the slag discharge port of filter press 5. Then, the electromagnet 4 is de-energized to release the adsorption of sulfide nano-zero valent iron, allowing the sulfide nano-zero valent iron to fall into the filter press 5. It is then discharged again through the slag discharge port of filter press 5, so that the sulfide nano-zero valent iron can be fully recycled and reused. After the entire reactor is placed on the ground, multiple sets of studs 9 are rotated by using a wrench, causing multiple sets of support blocks 8 to slide down a certain distance. This ensures that the reactor can still be placed stably even if there are minor unevennesses on the ground.

[0017] Please refer to this carefully. Figures 1 to 3 A motor 10 is fixedly connected to the top of the tank body 1. The motor 10 is located between the water inlet pipe 2 and the feed trough 3. The output end of the motor 10 is fixedly connected to a rotating shaft 11, which extends into the tank body 1. Two sets of crossbeams 12 are fixedly connected to the outer wall of the rotating shaft 11. Two sets of stirring cages 16 are rotatably connected between the two sets of crossbeams 12. The two sets of stirring cages 16 are located at both ends of the crossbeams 12. Two sets of gearboxes 13 are fixedly connected to the top of the upper set of crossbeams 12. The output end of each set of gearboxes 13 is fixedly connected to the top of a set of stirring cages 16. A set of rollers 14 is fixedly connected to the input end of each set of gearboxes 13. A pressure ring 15 is fixedly connected to the inner wall of the tank body 1. The bottom end of the pressure ring 15 abuts against the outer wall of the rollers 14.

[0018] The motor 10 drives the rotating shaft 11 to rotate, and the rotating shaft 11 drives the two sets of stirring cages 16 to revolve through the two sets of crossbeams 12. During this process, the crossbeams 12 drive the gearbox 13 and rollers 14 to rotate. The friction between the rollers 14 and the pressure ring 15 causes the rollers 14 to roll at the bottom of the pressure ring 15. During the rolling of the rollers 14, the gearbox 13 drives the stirring cages 16 to rotate, so that the stirring cages 16 and the crossbeams 12 can fully stir the sintering wastewater and sulfide nano-zero valent iron inside the tank 1, thereby promoting the reaction efficiency and making the reaction sufficiently thorough. After the reaction is completed, when the electromagnet 4 is started, during the process of the electromagnet 4 adsorbing the sulfide nano-zero valent iron, the motor 10 slowly drives the rotating shaft 11 to rotate, so that the sulfide nano-zero valent iron is fully suspended in the sintering wastewater, preventing the phenomenon that some of the sulfide nano-zero valent iron sinks to the bottom of the tank 1 and cannot be adsorbed by the electromagnet 4.

[0019] In use, sulfide nano-zero valent iron is added to sintering wastewater for reaction. The amount of sulfide nano-zero valent iron added is controlled by an intelligent program. After sufficient reaction time, the sulfide nano-zero valent iron is adsorbed by an electromagnet. Then, the treated wastewater is filtered and discharged through a filter press 5, thereby separating the sulfide nano-zero valent iron from the wastewater and other impurities, avoiding secondary pollution of the wastewater. The parts of this device not involved are the same as or can be implemented using existing technologies.
