Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of pharmaceutical equipment, in particular to a steam distribution device and a pharmaceutical system. BACKGROUND
[0002] High-temperature steam generated by a steam generator has strong sterilization ability and can completely kill bacteria, viruses and other microorganisms. In the pharmaceutical process, steam is widely used for sterilization and disinfection of equipment and containers to ensure a sterile production environment and prevent drug contamination. This step is crucial to ensure drug quality and safety.
[0003] However, current pharmaceutical systems are usually directly connected to steam users through pipelines from steam generators, which makes it difficult to meet the demand for steam flow when the number of use points increases or the demand for steam flow is large. Steam is prone to cause insufficient flow and insufficient pressure at the use points during peak use. In addition, the steam generated by the steam generator may contain impurities or incompletely vaporized water, which may not meet the strict requirements for steam purity when directly connected to the use points. The direct connection method reduces the flexibility of the steam distribution system. If the use points change or new use points are added, the steam pipeline may need to be redesigned and installed, increasing the complexity and cost of the system. CONTENT OF THE UTILITY MODEL

[0033] The following refers to Figure 1 The steam distribution device and pharmaceutical system according to some embodiments of the present application are described.
[0034] Referring to Figure 1 The embodiments of the first aspect of the present application provide a steam distribution device, which comprises a steam distribution cylinder 2 and a steam distribution assembly, the steam distribution assembly comprising a steam distribution pipeline 10, the steam distribution cylinder 2 being used to connect with a steam generator to store the steam generated by the steam generator, one end of the steam distribution pipeline 10 being used to connect with the steam distribution cylinder 2, and the other end of the steam distribution pipeline 10 being used to connect with a use point.
[0035] According to the above technical features, the steam distribution device stores the steam generated by the steam generator through the steam distribution cylinder 2, which can ensure the steam flow and steam pressure at the peak gas consumption on the one hand, and connect the use point and the steam distribution cylinder 2 through the steam distribution assembly to realize the steam supply of the steam distribution device to the use point, and the steam generated by the steam generator can be effectively stored in the steam distribution cylinder 2 to reduce the impurities or water vapor in the steam entering the use point, thereby ensuring the purity of the steam supply of the steam distribution device.
[0036] Preferably, as Figure 1As shown, the aforementioned steam distribution assembly may further include a pressure measuring unit 12 and a proportional regulating valve 13. The pressure measuring unit 12 is installed in the steam distribution pipeline 10 to monitor the air pressure of the steam distribution pipeline 10, and the proportional regulating valve 13 is installed in the steam distribution pipeline 10 to regulate the flow rate of the steam distribution pipeline 10. The pressure measuring unit 12 can be communicatively connected to the proportional regulating valve 13, so that the opening ratio of the proportional regulating valve 13 can be adjusted in real time by monitoring the air pressure of the steam distribution pipeline 10 through the pressure measuring unit 12, thereby further ensuring the stability and controllability of the air supply and air pressure of the steam distribution pipeline 10.
[0037] Optionally, the pressure measuring unit 12 can be a pressure transmission, flow meter, etc.
[0038] Preferably, such as Figure 1 As shown, the pressure measuring unit 12 is located at the end of the steam distribution pipeline 10 that is close to the point of use, so as to obtain the air pressure at the point of use of the steam distribution pipeline 10 more accurately, thereby ensuring the accuracy of the air supply volume of the steam distribution pipeline 10 to the point of use.
[0039] Preferably, such as Figure 1 As shown, the proportional control valve 13 is located at the end of the steam distribution pipeline 10 near the end connected to the steam distribution cylinder 2, so as to improve the response speed of the proportional control valve 13 to the airflow regulation of the steam distribution pipeline 10.
[0040] Preferably, such as Figure 1 As shown, the aforementioned steam distribution assembly may further include a first control unit 11. The first control unit 11 may be located at the end of the steam distribution pipeline 10 connected to the steam distributor cylinder 2, so as to control the airflow of the steam distribution pipeline 10, thereby improving the controllability of the steam distribution pipeline 10 and facilitating its maintenance. This ensures that if a fault occurs at any point of use or in the corresponding steam distribution assembly, the first control unit 11 of the corresponding steam distribution assembly can be quickly identified and shut down, ensuring that other points of use are not affected.
[0041] Optionally, the first control unit 11 mentioned above may be a ball valve.
[0042] Preferably, such as Figure 1 As shown, the above-mentioned steam distribution assembly may also include a sampling valve 14. The sampling valve 14 can be set between the pressure measuring unit 12 and the proportional regulating valve 13 in the steam distribution pipeline 10. On the one hand, the sampling valve 14 can be used to sample the gas in the steam distribution pipeline 10; on the other hand, setting the sampling valve 14 between the pressure measuring unit 12 and the proportional regulating valve 13 can effectively reduce the impact of the sampling operation on the gas supply flow at the point of use.
[0043] Preferably, the number of steam distribution assemblies can be multiple, on the one hand, to enable the steam distribution device to realize simultaneous independent steam supply to multiple use points, ensuring that each use point has sufficient steam; on the other hand, through the independent communication of multiple use points with the steam distribution cylinder 2 through the steam distribution assembly, not only can the steam use balance of multiple use points be ensured, but also the pressure and flow of the steam use point can be stabilized.
[0044] As shown in Figure 1 , the number of steam distribution assemblies is three, but this is not limited, and the number of steam distribution assemblies can be adaptively adjusted according to the number of use points.
[0045] Preferably, the number of steam distribution assemblies can be equal to the number of use points.
[0046] Preferably, the number of steam distribution assemblies can be greater than the number of use points, so that the steam distribution assemblies of the steam distribution device form redundancy, so that when a new use point is added, the newly added use point can be supplied with steam through the redundant steam distribution assemblies, effectively reducing the modification cost.
[0047] Preferably, the steam distribution assembly can be detachably connected with the steam distribution cylinder 2, so that when the number of use points is reduced, the steam distribution device can be adaptively modified by detaching the corresponding steam distribution assembly.
[0048] Preferably, as shown in Figure 1 , the steam distribution device can further include a steam supply pipeline 30 and a second control portion 31, the second control portion 31 can be provided on the steam supply pipeline 30, and the steam generator is connected with the steam distribution cylinder 2 through the steam supply pipeline 30 to control the on-off between the steam generator and the steam distribution cylinder 2, thereby ensuring the safety of the steam distribution cylinder 2.
[0049] Further, as shown in Figure 1 , the steam distribution device can further include a safety valve 22, which can be provided on the steam distribution cylinder 2, so that when the pressure of the steam distribution cylinder exceeds a threshold value, the safety valve 22 can be used to relieve the pressure of the steam distribution cylinder 2, thereby ensuring the safety of the steam distribution device.
[0050] Preferably, as shown in Figure 1 , the steam distribution device can further include a pressure gauge 21, which can be provided on the steam distribution cylinder 2 to facilitate real-time display of the pressure in the steam distribution cylinder 2.
[0051] Preferably, as shown in Figure 1As shown in the figure, the steam distribution device can further comprise an air supplement pipeline and a breather 23, which can be arranged at the steam distribution cylinder 2 via the air supplement pipeline to supplement air to the steam distribution cylinder 2 through the breather 23 when the steam distribution cylinder 2 is in a negative pressure state. On the one hand, timely air supplement through the breather 23 can effectively prevent the steam in the steam distribution cylinder 2 from condensing, causing the steam distribution cylinder 2 to deform due to the formation of negative pressure in the steam distribution cylinder 2. On the other hand, the filtering effect of the breather 23 can effectively prevent the steam in the steam distribution cylinder 2 from being polluted during the negative pressure air supplement of the breather 23.
[0052] Preferably, as shown in the figure, Figure 1 As shown in the figure, the steam distribution device can further comprise a one-way valve 24, which can be arranged at the air supplement pipeline and arranged between the breather 23 and the steam distribution cylinder 2 to prevent air leakage of the steam distribution cylinder 2 to the outside through the breather 23 and ensure the air tightness of the steam distribution cylinder 2.
[0053] Preferably, as shown in the figure, Figure 1 As shown in the figure, the steam distribution device can further comprise a fourth control part 25, and the air supplement pipeline is connected with the steam distribution cylinder 2 via the fourth control part 25 to control the opening and closing of the air supplement pipeline, thereby facilitating the maintenance and replacement of the breather 23 and the one-way valve 24.
[0054] Optionally, the fourth control part 25 can also be a ball valve.
[0055] Preferably, as shown in the figure, Figure 1 As shown in the figure, the steam distribution device can further comprise a liquid discharge pipeline 40 and a third control part arranged at the liquid discharge pipeline 40, and the liquid discharge pipeline 40 is connected with the bottom of the steam distribution cylinder 2 to facilitate the discharge of the steam liquefied liquid in the steam distribution cylinder 2.
[0056] Preferably, as shown in the figure, Figure 1 As shown in the figure, the third control part can comprise a drain valve 42 to ensure that the steam liquefied liquid in the steam distribution cylinder 2 can be discharged in time when the amount of the steam liquefied liquid reaches a certain amount, thereby effectively ensuring the dryness and saturation of the steam in the steam distribution cylinder 2.

[0058] The embodiments of the second aspect of the present application also provide a pharmaceutical system comprising the steam generator, the use point and the steam distribution device of any of the embodiments, thereby having all the beneficial technical effects of the steam distribution device, which will not be described here.
[0059] It should be noted that the above use point can be understood as a connection point of the device using steam which is connected with the steam distribution device.
