Description

Technical Field

[0001] The utility model belongs to the technical field of germanium tetrachloride production technology, and particularly relates to a device for pretreating complex regenerated germanium raw materials containing multiple metals. Background Art

[0002] Germanium-containing powders are packaged in high-pressure, light-strip bags. During pretreatment, they need to be poured into a container filled with sodium hydroxide solution for a reaction. The specific chemical reaction equation is: Ge + 2NaOH + H2O = Na2GeO3 + 2H2↑. Currently, this is often done manually, making it difficult to add uniformly or easily causing the material to clump together. This can lead to excessive amounts of germanium-containing material being poured in too quickly, resulting in an unsafe reaction and material ejection. Furthermore, germanium-containing materials may contain many active metals, such as aluminum and silicon, which also react readily with the sodium hydroxide solution. The specific chemical reaction equation is: 2Al + 2NaOH + 2H2O = 2NaAlO2 + 3H2↑. This reaction is quite intense, producing hydrogen. Since hydrogen is colorless, odorless, highly flammable, and explosive at high temperatures, improper handling can create a dangerous and complex environment for the decomposition of the germanium-containing material, causing large amounts of material to be ejected along with the hot sodium hydroxide solution, resulting in significant material loss and injury to operators.

[0003] After the previous reaction, the germanium-containing material must undergo an oxidation reaction with a large amount of strong oxidant to convert the solid into a liquid state and more completely evaporate the germanium tetrachloride. This is a lengthy chemical reaction process. Adding the strong oxidant too quickly can lead to an overly intense reaction, causing the high-temperature material to spray out, resulting in material loss and injuries. Conversely, adding the strong oxidant too slowly can cause the material to not react and fail to oxidize, resulting in incomplete decomposition and material loss. Utility Model Content

[0004] In order to solve the problems existing in the above background technology, the present invention proposes a pretreatment device for germanium-containing materials.

[0005] A pretreatment device for germanium-containing materials is characterized by comprising a reactor, a treatment reactor, a material pipeline, a speed control valve, a flow meter and a camera. A material inlet and an exhaust gas outlet are provided on one side of the top of the reactor body, the exhaust gas outlet is connected to a vertically upward exhaust pipe, and a strong oxidant inlet is provided on the other side of the top of the reactor body; the treatment reactor is arranged at a position at least 3m away from the reactor, the discharge port at the bottom of the treatment reactor is connected to the material pipeline and a material speed control valve is provided, the material pipeline is connected to the material inlet of the reactor, a camera is provided next to the material inlet of the reactor, and the camera is connected to a computer or mobile phone via a Wi-Fi signal; the strong oxidant inlet is connected to the strong oxidant pipeline, and a strong oxidant speed control valve and a flow meter are provided on the pipeline.

[0006] The beneficial effects of the present invention are as follows: a treatment kettle is installed at a distance of at least 3 meters from the reactor, and the material in the treatment kettle is fully stirred and reacted to change from a powder solid state to a liquid state, and flows into the reactor through a material pipeline to prevent the material from being sucked away by the tail gas, so that the feeding size is more uniform. A camera is installed at the reactor mouth to observe the size of the reaction in the kettle, thereby adjusting the amount of material input and the amount of strong oxidant to control the reaction speed in the kettle. People do not feed and observe the reaction at the reactor mouth, reducing the risk of personal injury. At the same time, the strong oxidant rate control valve and flow meter can control the strong oxidant introduction speed to control the material input size, and adjust the material to the most suitable and safest input speed. Various operations do not require observing the reaction in the kettle at the kettle mouth, but can be performed by remotely observing the reaction situation through the camera connected to your mobile phone, remotely controlling the material and strong oxidant input speed, reducing material loss and improving safety.

[0009] Example 1: A pretreatment device for germanium-containing materials, comprising a reactor 1, a treatment reactor 5, a material pipeline 6, a rate control valve, a flow meter 9 and a camera 8. A material inlet 2 and an exhaust gas outlet 4 are provided on one side of the top of the reactor body of the reactor 1. The exhaust gas outlet 4 is connected to a vertically upward exhaust pipe, and a strong oxidant inlet 3 is provided on the other side of the top of the reactor body; the treatment reactor 5 is arranged at a position at least 3m away from the reactor 1, and the bottom discharge port of the treatment reactor 5 is connected to the material pipeline 6 and a material rate control valve 7 is provided. The material pipeline 6 is connected to the material inlet 2 of the reactor 1, and a camera 8 is provided next to the material inlet 2 of the reactor 1, and the camera 8 is connected to a computer or mobile phone via a wifi signal; the strong oxidant inlet 3 is connected to the strong oxidant pipeline, and a strong oxidant rate control valve 10 and a flow meter 9 are provided on the pipeline.

[0010] Germanium-containing powder and a certain amount of clean water are added to a processing kettle 5. Stirring is initiated to fully blend the material and water, transforming the solid powder into a fluid liquid. The liquid material is then fed into the reactor 1 through a material pipe 6. The material rate control valve 7 regulates the amount of material solution added, thereby controlling the reaction. A flow meter 9 and a strong oxidant rate control valve 10 on the oxidant inlet pipe control the amount of strong oxidant added, thereby controlling the reaction within the reactor 1. A camera 8 on the port of the reactor 1 allows operators to remotely view the reaction within the reactor using their mobile phone. All operators remain away from the material reactor, ensuring the safety of both personnel and materials.
