Abstract

Technical Field
[0001] This utility model belongs to the field of sterile water production technology, specifically relating to a sterilization system for sterile water production. Background Technology
[0002] Sterile water refers to water that is free of bacteria by treating water containing bacterial colonies through physical methods. These methods include steam sterilization, UHT thermal sterilization, ultraviolet sterilization, ozone sterilization, and physical filtration, which kill and filter microorganisms in the water to obtain sterile water.
[0003] Sterile water is required in dairy production. To avoid affecting the taste of dairy products, pure water is usually sterilized by high-temperature steam heating. Existing equipment directly discharges the steam after high-temperature steam sterilization, which cannot make full use of the water vapor and results in a large waste of water resources and steam heat energy.

[0019] Example
[0020] like Figure 1 - Figure 4 As shown, a sterilization system for aseptic water production includes an outer shell 1. A steam box 2 is fixedly installed in the inner cavity at the top of the outer shell 1. A steam inlet pipe 3, whose bottom end communicates with the inner cavity of the steam box 2, is fixedly connected to the upper surface of the outer shell 1. A cooling device is installed inside the outer shell 1 below the steam box 2. A water storage structure is installed in the inner cavity at the bottom of the outer shell 1. A sterilization pipe 4 passes through one side of the top of the outer shell 1. One end of the sterilization pipe 4 inside the outer shell 1 passes through the steam box 2 and the cooling device and extends into the water storage structure. The middle section of the sterilization pipe 4 in both the steam box 2 and the cooling device has an S-shaped structure. A pipe connector 5 is fixedly connected to one end of the sterilization pipe 4 located outside the outer shell 1. The section of the sterilization pipe 4 located inside the steam box 2 and the cooling device is set in an S-shaped structure, which can greatly increase the contact surface between the sterilization pipe 4 and the hot steam and cooling water, so as to achieve the purpose of rapid heating and rapid cooling of the pure water inside the sterilization pipe 4. The pipe connector 5 is installed on the sterilization pipe 4 to facilitate connection with the external pure water pipe, so that the pure water flows along the sterilization pipe 4. When the pure water passes through the inside of the steam box 2, the steam inlet pipe 3 is used to transport high-temperature hot steam into the steam box 2 to sterilize the pure water at high temperature.
[0021] The cooling device includes a cooling water tank 6 fixedly installed on the inner wall of the outer shell 1. A circulating water pump 7 with its drain end connected to the inner cavity of the cooling water tank 6 is installed on one side of the outer wall of the outer shell 1. A water pump pipe 8 is installed on the water pump 7. When the sterilized pure water flows through the cooling water tank 6, the circulating water pump 7 delivers a large amount of cold water to the cooling water tank 6 to quickly cool the sterilized pure water.
[0022] A drain pipe 14 is fixedly connected to the bottom of the cooling water tank 6. The end of the drain pipe 14 away from the cooling water tank 6 passes through the side wall of the outer shell 1 and is connected to the external return water pipe. The inner diameter of the drain pipe 14 is smaller than the inner diameter of the water pumping pipe 8. The drain pipe 14 is set to discharge the cold water after heat exchange from the cooling water tank 6 to realize cold water circulation and improve cooling efficiency.
[0023] A connecting pipe is fixedly connected to one side of the bottom of the steam box 2, penetrating the outer shell 1 and extending to the outside of the outer shell 1. A three-way connector 9 is vertically installed at the end of the connecting pipe outside the outer shell 1. A condensate pipe 10 is fixedly connected to the bottom of the three-way connector 9. The end of the condensate pipe 10 away from the three-way connector 9 is connected to the water pumping pipe 8. When the high-temperature steam in the steam box 2 exchanges heat with the sterilization pipe 4 to form condensate, the condensate can be discharged into the water pumping pipe 8 along the condensate pipe 10 installed at the bottom of the three-way connector 9, and then transported to the cooling water tank 6 along the water pumping pipe 8 to participate in the cooling of the pure water in the sterilization pipe 4, thereby realizing the recycling of steam condensate and minimizing the waste of water resources.
[0024] A steam pipe 11 is fixedly connected to the top of the three-way connector 9. A preheating sleeve 12 is fitted on the section of the sterilization pipe 4 located outside the outer shell 1. The two ends of the preheating sleeve 12 are sealed. The end of the steam pipe 11 away from the three-way connector 9 passes around the top of the outer shell 1 and connects to the inside of the preheating sleeve 12. An exhaust pipe 13 connected to the inside of the preheating sleeve 12 is also fixedly connected to the bottom wall of the preheating sleeve 12. The high-temperature steam that has not condensed into liquid is transported along the steam pipe 11 to the inside of the preheating sleeve 12 to preheat the pure water in the section of the sterilization pipe 4 located outside the outer shell 1, so as to make full use of the heat energy of the high-temperature steam.
[0025] The water storage structure includes a water storage tank 15 located below the cooling water tank 6. The water storage tank 15 is made of transparent material. A nozzle 16 is installed at one end of the sterilization pipe 4 located in the inner cavity of the water storage tank 15. Ultraviolet lamps 17 are installed on the side walls of the outer shell 1 on both sides of the water storage tank 15. When the pure water is cooled in the cooling water tank 6, it can be sprayed into the water storage tank 15 through the nozzle 16. Since the water storage tank 15 is made of transparent material, the ultraviolet lamps 17 on both sides can fully irradiate the pure water stored in the water storage tank 15 to disinfect the pure water with ultraviolet light, so as to avoid the problem of bacteria re-generating after the pure water is stored for a long time.
[0026] A water outlet pipe 18 is fixedly installed at the bottom of the water storage tank 15, with one end communicating with the inner cavity of the water storage tank 15. The other end of the water outlet pipe 18 passes through the side wall of the outer shell 1 and extends to the outside of the outer shell 1. A solenoid valve 19 is installed at the connection between the water outlet pipe 18 and the water storage tank 15. When it is necessary to use the sterile water stored in the water storage tank 15, the solenoid valve 19 can be opened to discharge the sterile water along the water outlet pipe 18.
[0027] It should be noted that, in use, this sterilization system for sterile water production first delivers high-temperature steam through the steam inlet pipe 3 into the steam chamber 2. Then, the sterilization pipe 4 is connected to an external pure water pipe, allowing pure water to flow along the sterilization pipe 4. When the pure water flows through the steam chamber 2, it is instantly heated by the high-temperature steam to achieve high-temperature sterilization. After the high-temperature steam in the steam chamber 2 exchanges heat with the sterilization pipe 4 to form condensate, the condensate is discharged into the pump pipe 8 through the condensate pipe 10 installed at the bottom of the tee joint 9, and then transported to the cooling water tank 6 through the pump pipe 8 to participate in the cooling of the pure water in the sterilization pipe 4, thus realizing the recycling of steam condensate. The high-temperature steam that has not condensed into liquid is transported to the preheating sleeve 12 through the steam pipe 11 to preheat the pure water in the section of the sterilization pipe 4 located outside the outer shell 1, thus making full use of the high-temperature steam and minimizing the waste of water resources and steam heat energy.
[0028] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
