Description

Technical Field

[0001] This utility model belongs to the field of water treatment and is a novel reaction device for the recovery of zero-valent iron materials after reaction. Background Technology

[0002] In laboratory treatment of industrial wastewater and heavy metal wastewater, zero-valent iron (ZVFe) plays a crucial role due to its easy availability, high reducing power, and lack of toxic or harmful substances, making it a vital iron resource. However, ZVFe is prone to agglomeration due to its magnetic properties and high surface energy. ZVFe reacts with H₂O and O₂ in solution to form an iron oxide layer on its surface, which affects the dispersion stability and utilization rate of the particles. Furthermore, the difficulty in recovering ZVFe from the reaction system limits its application and leads to a waste of iron resources.

[0003] When zero-valent iron is used to degrade pollutants, conventional magnetic stirrers tend to attract zero-valent iron onto the magnetic poles, making it difficult for the iron to react evenly with the solution. Mechanical stirrers, on the other hand, have the disadvantages of uneven stirring of zero-valent iron and easy aggregation and precipitation. Utility Model Content

[0004] To address the shortcomings of the existing technology, this invention provides a novel reaction device suitable for treating wastewater with zero-valent iron, accelerating uniform reaction, and enabling the recycling of materials after the reaction.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows.

[0006] A novel funnel-shaped reaction apparatus for the recovery of zero-valent iron materials after reaction is disclosed. The apparatus includes a reactor body, a stirring device, and a generating device. The stirring device, adjustable in height via a knob, comprises a rotary motor and a stirring rod positioned below the motor. A control panel is located on the side of the rotary motor. A fixed plate is connected to the lower end of the stirring rod, and the edge of the fixed plate has evenly spaced fan blades. The fan blades are placed inside the reactor containing the reaction solution, and a mesh funnel for attaching the material is placed at the top of the reactor. The funnel contains a permanent magnet and is covered with a removable nano-ceramic coating protective shell.

[0007] In the aforementioned funnel-shaped novel reaction device for the recovery of zero-valent iron materials after reaction, the rotary motor is connected to a power source via a wire.

[0008] In the aforementioned funnel-shaped novel reaction device for the recovery of zero-valent iron materials after reaction, the fan blades are three in number, made of carbon fiber material, and have serrated edges.

[0009] In the aforementioned funnel-shaped novel reaction device for the recovery of zero-valent iron materials after reaction, the reactor body is made of cylindrical glass.

[0010] In the aforementioned funnel-shaped novel reaction device for the recovery of zero-valent iron materials after reaction, the funnel is a hollow inverted frustum-shaped mesh structure with openings at the top and bottom, and is made of permanent magnets; the shaded part on its surface is the material adsorption area, and the blank part is hollowed out.

[0011] In the aforementioned funnel-shaped novel reaction device for the recovery of zero-valent iron materials after reaction, the inside and outside of the funnel are covered with a detachable nano-ceramic coating of the same shape and structure.

[0012] In the aforementioned funnel-shaped novel reaction device for the recovery of zero-valent iron materials after reaction, the surface of the nano-ceramic coating is uniformly covered with zero-valent iron materials.

[0013] In the aforementioned funnel-shaped novel reaction device for the recovery of zero-valent iron materials after reaction, the stirring device is connected to the main body of the reaction device via a base and a fixing device.

[0014] In the aforementioned funnel-shaped novel reaction device for the recovery of zero-valent iron materials after reaction, the base and fixing device are connected by threads or bolts, which facilitates disassembly, installation, and maintenance.

[0015] In the aforementioned funnel-shaped novel reaction device for the recovery of zero-valent iron materials after reaction, the reactor body is open at the top and does not have separate inlet and outlet ports.

[0016] Compared with existing technologies, the beneficial effects of this invention are as follows: 1) The inner layer of the funnel in this invention is a permanent magnet layer, which generates a strong magnetic field and effectively adsorbs zero-valent iron; the outer layer is a removable nano-ceramic coating protective film, which not only protects the magnet from corrosion, but also has good hydrophilicity and self-cleaning properties, reducing the residue of zero-valent iron on the surface of the funnel and facilitating the recovery of zero-valent iron. 2) This invention utilizes the serrated structure of the fan blade edge, which generates stronger turbulence during stirring, promoting full contact and reaction between pollutants and zero-valent iron. 3) Before the reaction, the zero-valent iron material is evenly spread on the inner and outer surfaces of the funnel covered with the protective film, effectively increasing the contact area between pollutants and zero-valent iron, thereby making the reaction more complete and improving the utilization rate of zero-valent iron; solid-liquid separation can also be achieved through the handle, quickly terminating the reaction and completing the recovery of zero-valent iron. 4) The reactor body of this invention is made of glass, making the entire device relatively lightweight.

[0020] To better understand the present invention, the following description, in conjunction with the accompanying drawings, further illustrates the content of the present invention.

[0021] like Figure 1-3 As shown, a novel funnel-shaped reaction device for recovering zero-valent iron materials after reaction includes a support frame 1. The upper end of the support frame is connected to a rotary motor 4 via a knob 2 for easy vertical adjustment. The rotary motor is connected to a power source via a wire 3 and has a control area 5 on its side for adjusting the rotation speed. The lower end of the rotary motor 4 is connected to a stirring rod 6, and the lower end of the stirring rod 6 is connected to a fixed disk 10. The fixed disk 10 has three equally spaced fan blades 9 on its edge, and the edges of the fan blades 9 are serrated 11. The funnel 7 is a hollow mesh structure made of permanent magnets. The shaded areas on its surface are material adsorption areas, and the blank areas are hollowed out, which facilitates the full and uniform contact and reaction between zero-valent iron and the pollutant solution. Both the inner and outer surfaces of the funnel 7 are covered with a removable nano-ceramic coating 13 of the same shape to protect the internal magnets from solution corrosion. Before the reaction, zero-valent iron material is evenly spread on the coating 13 on the surface of the funnel 7. Then, the funnel 7 is placed inside the reactor 8. Finally, the knob 2 is adjusted to position the fan blades 9 appropriately inside the funnel 7, avoiding collisions with the bottom of the reactor 8 and the funnel 7. During the reaction, solid-liquid separation can also be achieved through handle 12, which can quickly terminate the reaction and complete the recovery of zero-valent iron.
