Abstract
Description
Technical Field
[0001] This utility model belongs to the field of static sterile water systems, specifically, it relates to a static sterile water system. Background Technology
[0002] In the production processes of dairy products, food processing, and pharmaceuticals, aseptic water systems are a crucial component for ensuring product quality and safety. Aseptic water is widely used in cleaning production equipment, preparing solutions, and product filling, effectively preventing microbial contamination. However, traditional aseptic water systems have several shortcomings in their design and use, resulting in high system stability and maintenance costs, failing to fully meet the high standards required by modern production.
[0003] Currently, the most common sterile water systems on the market mainly adopt dynamic circulation sterile water system solutions:
[0004] Dynamic circulation systems maintain a sterile environment by continuously circulating water. This design requires water to circulate at a certain flow rate within the pipes to prevent bacterial growth, and water quality is maintained through methods such as ultraviolet sterilization, ozone treatment, or online steam sterilization. However, these systems have high operating costs and require continuous power to maintain water circulation. Furthermore, the high-speed water flow can easily cause pipe wear, increasing the difficulty and risk of system maintenance. Dynamic circulation systems require continuous operation of pumps and disinfection equipment to maintain stable water flow and quality, resulting in high energy consumption. Additionally, pressurized systems rely on complex pressure control equipment, which also increases energy consumption. Utility Model Content
[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a static sterile water system, which solves the problems mentioned in the background art.
[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:
[0007] A static sterile water system includes: a first pipe; a second pipe connected to the middle left side of the first pipe; a third pipe located to the right side of the second pipe; a fourth pipe located to the right side of the first pipe; a process water inlet valve located in front of the inlet of the first pipe; a mass flow meter located in front of the process water inlet valve; four inlet control valves located in front of the mass flow meter; a primary water filter installed in front of the inlet control valves; a precision water filter installed in front of the primary water filter; three outlet control valves installed in front of the precision water filter; an outlet negative pressure valve located at the end of the first pipe; a clean air inlet valve located at the front of the air inlet of the second pipe; a clean air filter pressure reducing valve located in front of the clean air inlet valve; a clean air control valve located to the right front of the clean air filter pressure reducing valve; a steam inlet valve located in front of the air inlet of the third pipe; a clean steam filter located in front of the steam inlet valve; a steam pressure reducing valve located in front of the clean steam filter; and multiple steam trap control valves installed at the lower end of the connection point between the third pipe and the first pipe. It should be noted that all electrical devices involved in this application can be powered by batteries or external power sources.
[0008] Optionally, the first pipe is curved, the second and third pipes are in reverse L-shapes, and the fourth pipe is L-shaped.
[0009] Optionally, the connection points between the second and third pipes and the first pipe are located between the primary water filter and the precision water filter, with the precision water filter located in front of the primary water filter.
[0010] Optionally, the rear end connection of the fourth pipe is located at the last end of the inlet control valve, and the rear end connection of the fourth pipe is located at the front end of the outlet control valve.
[0011] Optionally, the connection end of the steam trap control valve to the first pipe is located in front of the connection end between the third pipe and the first pipe.

[0013] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:
[0014] 1. This static sterile water system utilizes a combination of a process inlet valve, a mass flow meter, an inlet control valve, a primary water filter, a precision water filter, an outlet control valve, an outlet negative pressure valve, a clean air inlet valve, a clean air filter pressure reducing valve, a clean air control valve, a steam inlet valve, a clean steam filter, a steam pressure reducing valve, and a steam trap control valve. In production mode, process water enters through the process inlet valve, and the inlet control valve ensures stable water flow. The system can be equipped with a mass flow meter to precisely control the water volume as needed. The process water passes through the primary water filter to remove suspended solids, impurities, and algae spores with a diameter greater than μm. After filtration, impurities trapped in the coarse filter element can be discharged through a periodic drain valve to ensure the long-term effective operation of the filter element. The coarsely filtered process water then enters the final precision water filter. The μm filter element further removes bacteria and particles, ensuring that the filtered water meets sterile water standards. In sterilization mode, clean air is first used for drainage, and steam enters the system through the clean air inlet valve. The flow rate and temperature are controlled by the inlet valve to ensure a stable steam supply. The steam passes through the clean air filter pressure reducing valve, and the pressure is adjusted to bar to ensure that it will not damage the system during sterilization while ensuring sterilization effect. The pressure-regulated steam enters the precision water filter through the clean air control valve for high-temperature sterilization of the filter element and the system. The sterilization temperature is maintained at ℃ for minutes. The system has temperature and time monitoring functions to ensure that the sterilization process is strictly followed. The multi-stage filtration design ensures stable water quality, meeting the high standards required for dairy products and food processing. The static structure avoids the high energy consumption problem of dynamic circulation systems, reducing operating costs. The high-temperature steam sterilization method ensures a sterile environment inside the system, avoiding secondary contamination. The pressure reducing valve controls the steam pressure to prevent equipment damage and improve system stability. The system adopts a removable filter element and an automatic sewage discharge design to reduce the frequency of manual maintenance. The automated control system supports remote monitoring and emergency operation, reducing the risk of human intervention. It eliminates the need for dynamic circulation, reducing energy consumption and carbon emissions. The system employs efficient steam sterilization, minimizing the use of chemical reagents. This invention's static sterile water system overcomes the problems of high energy consumption, significant pollution risk, and difficult maintenance inherent in existing technologies by combining multi-stage filtration with high-temperature steam sterilization. The system's static design eliminates the need for dynamic circulation, effectively reducing operating costs, and achieves a highly efficient and stable supply of sterile water through automated control.
