[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] In some embodiments, please refer to the accompanying drawings. Figure 1 A high-performance glyceryl acetate delivery pipeline includes: a first storage module for storing glyceryl acetate; a staged heating module for staged heating of glyceryl acetate; a cleaning module for cleaning impurities from the glyceryl acetate; and a second storage module for storing the heated and cleaned glyceryl acetate.

[0028] In this embodiment, the graded heating module consists of a first-stage heating device, a second-stage heating device, and a third-stage heating device. The first-stage heating device is connected to the first liquid storage module and the second-stage heating device via pipelines. The third-stage heating device is connected to the second-stage heating device and the cleaning module via pipelines. The first liquid storage module consists of a liquid storage tank, a circulation pump, and a purity detector. The outlet of the liquid storage tank is connected to the circulation pump via a pipeline. The purity detector is installed on the circulation pump. The circulation pump has two sets of outlets. One set of outlets is connected to the inlet of the liquid storage tank via a pipeline, and the other set of outlets is connected to the first-stage heating device via a pipeline.

[0029] The utility model utilizes modular piping connections between a first-stage heating device, a second-stage heating device, a third-stage heating device, and a first liquid storage module and a cleaning module, resulting in a highly flexible and scalable system. Each module can operate independently and is easily replaced or upgraded according to actual needs, thereby improving the system's adaptability and ease of maintenance.

[0030] In this embodiment, the first-stage heating device consists of a steam heat exchange pump, a hot steam tank, and a waste heat absorption assembly. The other set of liquid outlets of the circulating pump is connected to the liquid inlet of the steam heat exchange pump via a pipeline. The air inlet of the steam heat exchange pump is connected to the air outlet of the hot steam tank via a pipeline. The liquid outlet of the steam heat exchange pump is connected to the liquid inlet of the second-stage heating device via a pipeline. The air outlet of the steam heat exchange pump is connected to the waste heat absorption assembly via a pipeline. The waste heat absorption assembly is a vacuum pump plate heat exchanger. The second-stage heating device is a solar heat exchanger. The liquid inlet of the solar heat exchanger is connected to the liquid outlet of the steam heat exchange pump via a pipeline. The liquid outlet of the solar heat exchanger is connected to the third-stage heating device via a pipeline. The first-stage heating device utilizes the steam heat exchange pump to exchange heat with the hot steam tank, effectively increasing the liquid temperature. Simultaneously, the waste heat generated during the steam heat exchange process is recovered through the vacuum pump plate heat exchanger, improving energy utilization efficiency. This connection method ensures heating efficiency and achieves energy recycling.

[0031] The three-stage heating device is an electric heating heat exchange plate. The liquid inlet of the electric heating heat exchange plate and the liquid outlet of the solar heat exchange plate are connected by a pipeline. The liquid outlet of the electric heating heat exchange plate and the cleaning module are connected by a pipeline.

[0032] A closed-loop circuit is formed between the circulating pump and the storage tank, ensuring continuous circulation and renewal of the liquid within the system. Simultaneously, the integrated application of a purity analyzer allows for real-time monitoring of the liquid's purity, ensuring the stability and safety of the system's operation. This connection method enhances the system's automation and intelligence levels.

[0033] The system combines multiple heating methods, including steam heat exchange (first-stage heating device), solar heating (second-stage heating device), and electric heating (third-stage heating device), achieving diversified energy utilization. This complementary heating method not only improves the system's heating capacity and stability but also reduces dependence on a single energy source, enhancing the system's environmental adaptability and economic efficiency.

[0034] In this embodiment, the cleaning module is a cleaning tower. The inlet of the cleaning tower and the outlet of the electric heating heat exchange plate are connected by a pipeline. The outlet of the cleaning tower and the second storage module are connected by a pipeline. The glyceryl acetate that has cooled and solidified at the bottom of the cleaning tower is connected to the storage tank by a pipeline. Since glyceryl acetate may contain grease, it is necessary to use an appropriate degreasing agent (such as NaOH alkaline solution) for circulating cleaning to remove the grease. During the cleaning process, it should be ensured that the degreasing agent is in full contact with the glyceryl acetate and that the cleaning is circulated until the grease is completely removed.

[0035] In this embodiment, ester acetate is stored in a storage tank and then pumped out by a circulation pump. The purity of the ester acetate is tested by a purity tester. The ester acetate that passes the test is transported to a steam heat exchange pump through a set of outlets in the circulation pump. If the ester acetate that fails the test is transported back to the storage tank through a pipeline to continue to precipitate, and this cycle is repeated.

[0036] After passing the test, the acetic acid ester is transported through pipelines to a steam heat exchange pump for the first heating. The heat source of the steam heat exchange pump is supplied by a hot steam pipe. The steam after heat exchange is recovered by a vacuum pump plate heat exchanger. The acetic acid ester after absorbing heat is transported through pipelines to a solar heat exchange plate for the second heating.

[0037] After the second heating, the ester of acetic acid is transported through pipeline to an electric heating heat exchange plate for a third heating. After the third heating, the ester of acetic acid is transported through pipeline to a cleaning tower for cleaning. After cleaning, the ester of acetic acid enters the product storage tank through pipeline. The ester of acetic acid that has been cooled and precipitated in the cleaning tower is returned to the storage tank for storage through the accumulation tank.

[0038] In this embodiment, the second liquid storage module is a product storage tank, which has a constant temperature stirring function. The inlet of the product storage tank and the outlet of the cleaning tower are connected by a pipeline.

[0039] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
