Description

Technical Field

[0001] This utility model relates to the field of methoxyamine hydrochloride production technology, specifically to a wastewater treatment device for the preparation of methoxyamine hydrochloride. Background Technology

[0002] Traditional methods for synthesizing methoxyamine hydrochloride include the ketoxime method, the ethyl acetate method, and the sodium bisulfite method. Currently, the conventional industrial production process for methoxyamine hydrochloride generally uses sulfur dioxide, sodium nitrite, and hydroxylamine as the main raw materials. The process involves a Schick reaction to produce hydroxylamine disulfonate, followed by methylation with dimethyl sulfate under specific temperature and pH conditions, and then hydrolysis to obtain the product methoxyamine. However, this process has a significant drawback: on average, producing one ton of methoxyamine hydrochloride generates over ten tons of sodium sulfate wastewater. Therefore, the sodium sulfate wastewater after the reaction needs to be treated to render it harmless. In existing technologies, when dealing with sodium sulfate wastewater, a suitable amount of chemical precipitant (such as calcium, aluminum, and iron metal salts) is added to react with the sodium sulfate in the wastewater, forming water-insoluble calcium sulfate, bauxite, or iron salt precipitates. These precipitates then settle to the bottom, and the sodium sulfate is removed through separation and treatment. However, existing precipitants are typically added by surface spraying, resulting in poor uniformity. Furthermore, the precipitant moves from the surface to the bottom, leading to insufficient contact between the wastewater and the precipitant at the bottom. This is especially problematic when the sedimentation tank is large and the wastewater volume is high, further impacting treatment efficiency and effectiveness. Therefore, this project was developed to address these issues. Utility Model Content

A horizontal adjustment mechanism is mounted on the rotating support 4, and a moving seat 6 is mounted on the moving end of the horizontal adjustment mechanism. A storage hopper 7 is mounted on the moving seat 6, and the storage hopper 7 is filled with a precipitant and an aqueous solution. A reagent stirring assembly is mounted inside the storage hopper 7, and a pressurized spray assembly is connected to the lower part of the storage hopper 7. A fixed frame 8 is mounted on one side of the moving seat 6, and a rotating impact assembly is installed on the fixed frame 8. Some wastewater treatment systems improve upon circular sedimentation tanks 1 by installing a rotatable support 4 at the top of the tank. The support 4 is equipped with a horizontal adjustment mechanism. The precipitant and aqueous solution are filled into the storage hopper 7 on the movable base 6. A stirring assembly is used to agitate the precipitant, causing it to dissolve rapidly. The rotating impact assembly on the fixed frame 8 is activated, stirring the wastewater in the sedimentation tank while a pressurized injection assembly adds the precipitant solution. This allows the chemical precipitant to react quickly with the sodium sulfate in the wastewater.
