Description

Technical Field

[0001] This utility model relates to an oil-water separation device, and more particularly to an AKD automatic oil-water separation device based on a smart mirror. Background Technology

[0002] There are two main processes for AKD synthesis: one is the solvent-based process, with the main raw materials being triethylamine, fatty acid acyl chloride, and toluene, where toluene is the solvent. In the synthesis reaction, due to the presence of the solvent toluene, the materials have good fluidity and low viscosity, and a stirred mixing reaction mode is generally adopted.

[0003] Another method is the solvent-free process, with triethylamine and fatty acid acyl chloride as the main raw materials. In the solvent-free synthesis of AKD (a papermaking additive), the material viscosity is high in the later stages of the reaction, and it contains fine triethylamine hydrochloride solid particles. At a temperature of T=65℃, the material viscosity can reach 130,000 mPa·s. After the reaction, the triethylamine hydrochloride solid particles in the AKD product need to be dissolved in a solution to achieve stratification of AKD in the triethylamine hydrochloride aqueous solution, resulting in a high-purity AKD product. However, during the stratification process, some AKD will flow out of the solution into the amine salt tank, floating on top. The triethylamine hydrochloride needs to be extracted from the lower layer of the solution in the amine salt tank, minimizing AKD entrainment.

[0004] The production process involves multiple pickling and washing operations. After pickling and washing, manual stratification is required. During stratification, personnel must observe the fluid state through a sight glass to completely separate the aqueous phase, retaining the oil phase for subsequent processing to obtain the product. The operators use their experience and observations through the sight glass to control the valves for material separation. However, because the colors of different liquid phases are similar, operators are prone to misjudgment, leading to unnecessary waste. Furthermore, the operation relies entirely on the operator's skill level, making it difficult to ensure process consistency. The entire process relies on manual judgment and operation, hindering the development of information technology for the entire production process. The water separation process is time-consuming and requires manual handling, resulting in low efficiency and poor accuracy. Utility Model Content
