Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0019] Specific implementation examples are given below.
[0020] like Figures 1 to 5 As shown, an embodiment of this utility model provides a high-efficiency separation and purification equipment for bio-based ethylene glycol, including a mounting frame 11; a conveying mechanism 12 is mounted on the top of the mounting frame 11; a fixing frame 13 is fixedly connected inside the mounting frame 11; a filter box 14 is installed inside the fixing frame 13; a feed inlet 15 is opened on the top of the filter box 14; an inner box 16 is fixedly connected inside the filter box 14; the inner box 16 is located below the feed inlet 15; a filtration mechanism 17 is provided between the filter box 14 and the inner box 16; a discharge pipe 18 is fixedly connected to the side wall of the filter box 14; and a wastewater pipe 19 is fixedly connected to the bottom of the filter box 14. During operation, bio-based ethylene glycol separation is required. During purification, bio-based ethylene glycol can be conveyed to the inner tank 16 via the conveying mechanism 12. When the conveyed bio-based ethylene glycol reaches the inner tank 16, it flows between the filter box 14 and the inner tank 16 and is then filtered by the filter mechanism 17. This process removes impurities from the bio-based ethylene glycol, making the separation and purification of bio-based ethylene glycol more precise. The wastewater pipe 19 can discharge the waste material precipitated from the bio-based ethylene glycol in the inner tank 16. Through the above structure, suspended solids, colloids, macromolecular organic matter, and other impurities in the crude bio-based ethylene glycol product can be effectively removed, providing a purer raw material for subsequent purification steps.
[0021] like Figure 1As shown, a pump body 21 is installed on the top of the conveying mechanism 12; a conveyor 22 is connected to the bottom of the pump body 21; an inlet pipe 23 is connected to the side wall of the conveyor 22; a conveying pipe 24 is connected to the bottom of the conveyor 22, and the conveying pipe 24 is located inside the feed inlet 15; during operation, the inlet pipe 23 can be connected to the conveyor 22, and the pump body 21 drives the conveyor 22 to deliver bio-based ethylene glycol through the conveying pipe 24 into the filter box 14, thereby achieving precise control of the flow rate of the pump body 21, making the filtration more accurate and stable; through the above structure, it has high-precision control of the conveying speed and corrosion-resistant properties, making the operation more accurate and stable when conveying bio-based ethylene glycol.
[0022] like Figure 3 As shown, a filter cotton 31 is provided above the filter mechanism 17; a filter fiber 32 is provided below the filter mechanism 17. During operation, the filter mechanism 17, the filter cotton 31 and the filter fiber 32 can perform more detailed filtration, making subsequent purification more accurate. The above structure can be used for the filtration of ethylene glycol, which can better remove impurities and make subsequent purification and separation more accurate.
[0023] like Figure 4 As shown, a support frame 41 is placed on the top of the inner box 16; a buffer tank 42 is fixed to the bottom of the support frame 41; the buffer tank 42 is located inside the inner box 16; during operation, the support frame 41 can be embedded in the inner box 16, and then buffered by the buffer tank 42, making the transported bio-based ethylene glycol more stable and preventing unstable flow rate, which would cause turbidity in the inner box 16; through the above structure, unstable flow rate can be accepted, playing the role of storage and release, providing a relatively stable feed flow rate, and ensuring the stability of subsequent filtration.
[0024] like Figure 5 As shown, an interval filter plate 51 is fixedly connected inside the inner box 16; the interval filter plate 51 is located above the waste port; during operation, the interval filter plate 51 can be used for blocking treatment, which can cause the ethylene glycol to precipitate, so that the waste sinks to the bottom, making the ethylene glycol purer; through the above structure, it can be used to isolate the precipitate from the ethylene glycol, which can prevent filtration and make the filter mechanism 17 more pure.
[0025] like Figure 1 and Figure 3 As shown, the top of the filter box 14 is connected to an exhaust pipe 61; a filter 62 is installed on the top of the exhaust pipe 61; during operation, exhaust gas can be discharged to the outside through the exhaust pipe 61, and then filtered through the filter 62 to ensure that the discharged exhaust gas meets environmental emission standards; the above structure is used to treat the exhaust gas discharged during the separation and purification of bio-based ethylene glycol to remove harmful substances and meet environmental emission standards.
[0026] like Figure 1 As shown, a dustproof plate 71 is placed on top of the filter box 14; the dustproof plate 71 is located on top of the feed inlet 15; during operation, dustproof treatment can be carried out through the dustproof plate 71 to prevent dust from entering the interior and causing contamination of ethylene glycol; through the above structure, in order to effectively prevent dust from entering the equipment interior and to have good sealing performance, the dustproof effect is better improved.
[0027] Working Principle: During operation, when bio-based ethylene glycol separation and purification are required, the bio-based ethylene glycol is conveyed to the inner tank 16 via the conveying mechanism 12. When the conveyed bio-based ethylene glycol submerges the inner tank 16, it flows between the filter box 14 and the inner tank 16, where it is filtered by the filter mechanism 17. This filters out impurities within the bio-based ethylene glycol, making the separation and purification process more precise. The wastewater pipe 19 discharges the waste material precipitated from the bio-based ethylene glycol in the inner tank 16. The inlet pipe 23 can be connected to the conveyor 22, and the pump 21 drives the conveyor 22 to deliver the bio-based ethylene glycol through the conveying pipe 24 to the filter box 14. This allows for precise flow rate control by the pump 21, ensuring efficient filtration. More precise and stable; more detailed filtration can be achieved through the filter mechanism 17, filter cotton 31, and filter fiber 32, making subsequent purification more accurate; the support frame 41 can be embedded in the inner box 16, and then buffered through the buffer pool 42, making the transported bio-based ethylene glycol more stable and preventing unstable flow rate that could cause turbidity in the inner box 16; the partition filter plate 51 can be used for blocking treatment, which can cause the ethylene glycol to settle, allowing the waste to settle to the bottom, making the ethylene glycol purer; the exhaust gas can be discharged to the outside through the exhaust pipe 61, and then filtered through the filter 62, so that the discharged exhaust gas meets environmental emission standards; the dustproof plate 71 can be used for dustproof treatment, which can prevent dust from entering and causing ethylene glycol contamination.
[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
