Over the past decade, there has been tremendous development in chemical engineering equipment; this is a testament to the prosperity and strength of China. This post serves as a starting point for discussion; we hope more people will join in the conversation. With your participation, Haichuan becomes even more wonderful. Everyone is welcome to actively engage in discussions on the forum. Have a pleasant weekend! ********************************************* The Langjiu Large-Height-Difference Wine Transfer Pipeline Project is located within the jurisdiction of Langjiu’s Erlang Base. It is a key project that enables Langjiu to overcome geographical constraints posed by mountains and hills, thereby facilitating the efficient transportation of raw wine. The pipeline starts at the 50,000-ton wine storage facility in Huangjinba and ends at the 160,000-ton wine storage facility in Tianbaofeng. Construction began in May 2016 and took 9 months; it was completed and put into use in January 2017. Being a two-way, dual-channel wine transport pipeline, it enables automatic two-way transfer of wine between any tank in the 50,000-ton storage facility in Huangjinba and any tank in the various tank areas of the 160,000-ton storage facility in Tianbaofeng. It is the world’s first wine transport pipeline with the largest elevation difference. This pipeline incorporates a number of industry-leading technologies, which help to overcome the challenges associated with construction in areas featuring steep cliffs and high operational risks. The lowest point of the pipeline is at an altitude of 575 meters, while the highest point is at 845 meters; thus, the static height difference is 270 meters and the dynamic height difference is 350 meters. The total length of a single pipeline segment is 2023 meters. Two 110 KW high-efficiency shielded pumps designed for use in the food industry are employed, enabling a one-way wine transport capacity of 40–60 tons per hour. The total investment for this project amounts to 9.73 million yuan. This pipeline is equipped with a PLC-based automatic control system, along with anti-theft monitoring and vibration alarm systems, as well as fire and combustible gas alarm systems. Fiber optic interference technology was used for the first time in wine transportation systems; by leveraging changes in the properties of light and through specialized algorithms and analysis in the alarm controller, it is possible to accurately distinguish between unauthorized intrusions and normal disturbances, thereby enabling alarm activation and location determination. This ensures the protection of the pipelines throughout the process and guarantees safe operation.
The successful operation of the high-drop wine transfer pipeline has completely transformed the original transfer method, achieving \"one increase and three reductions\". “The transfer efficiency increases significantly with one liter of such system. Taking the transfer of 40,000 tons of raw liquor per year as an example, the original vehicles could only transfer 180 tons per day, requiring 223 days to complete the task; with the use of liquor transfer pipelines, 400 tons can be transferred per day, and the task can be completed in 100 days – meaning the transfer efficiency is more than doubled. The “three reductions” refer mainly to a decrease in labor costs, reduced energy consumption during transportation, and lower transportation expenses. For transporting 40,000 tons of raw liquor using the traditional method, 1,784 man-hours were required, while only 700 man-hours are needed with the new pipeline system; this alone results in annual savings of 209,200 yuan in labor costs. In terms of energy consumption, 2.2 kWh was required per ton transported previously, but now only 1.1 kWh is needed, representing a 50% reduction in energy use and annual savings of 31,200 yuan. The transportation cost under the new method is exactly zero, which alone yields annual savings of 2,090,000 yuan. Even after accounting for the cost of capital tied up in building new pipelines, an annual savings of 2.272 million yuan can be achieved, and the investment cost can be recovered within 4 years.

The warehouse area was completed over the course of a year, with a construction area of 10,600 square meters. It contains 68 stainless steel wine tanks, ranging in capacity from 50 to 1,000 tons, and is used primarily for processes such as blending and filtering wine for packaging production. The commissioning of the 19,000-ton wine storage facility at Tianbao Peak has raised the total storage capacity in the Erlang production area to over 260,000 tons, providing strong storage support for Langjiu.
