Detailed Implementation

[0018] This application is based on the findings and understanding of the following facts and issues: The dairy membrane concentration system in related technologies discharges large amounts of dialysis water directly and carelessly onto the ground, causing a serious waste of water resources.

[0019] Specifically, in the dairy processing system of the relevant technology, the condenser uses soft water prepared from tap water as a cold source to exchange heat with the hot fluid, and cools and condenses the hot fluid. The water consumption is large and the water cost is high. Moreover, the preparation of soft water requires energy consumption and generates equipment maintenance costs.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] The following description, with reference to the accompanying drawings, describes a dairy product dialysis water recovery system 1 according to an embodiment of the present invention.

[0023] like Figure 1 As shown, the dairy product dialysis water recovery system 1 according to an embodiment of the present invention includes a membrane concentration device 10, a recovery tank 20, a condenser 30, a recovery tank water level detection device 40, and a recovery tank pumping device 50.

[0024] The membrane concentration unit 10 has a dialysis water outlet 11. The recovery tank 20 has a recovery tank inlet 21 and a recovery tank outlet 22, with the inlet 21 connected to the dialysis water outlet 11. The condenser 30 is connected to the recovery tank outlet 22. A recovery tank level detection device 40 is installed on the recovery tank 20. A recovery tank pumping device 50 is connected between the recovery tank outlet 22 and the condenser 30, and is electrically connected to the recovery tank level detection device 40.

[0025] Specifically, the membrane concentration equipment 10 can be an RO membrane concentration equipment.

[0026] After the milk source enters the membrane concentration equipment 10, it is filtered and the concentrate enters the next process. Dialysis water is discharged through the dialysis water outlet 11 and enters the recovery tank 20 for storage through the recovery tank inlet 21. The recovery tank water level detection device 40 detects the water level in the recovery tank 20. When the water level detection device 40 detects that the water level in the recovery tank 20 is high, the recovery tank pumping device 50 delivers water through the recovery tank outlet 22 to the condenser 30. The dialysis water is used as a cold source to exchange heat with the hot fluid, cooling and condensing the hot fluid to achieve the recovery and reuse of the dialysis water. When the water level detection device 40 detects that the water level in the recovery tank 20 is low, the recovery tank pumping device 50 stops operating.

[0027] According to the dairy dialysis water recovery system 1 of this utility model embodiment, by setting up a recovery tank 20, the dialysis water outlet 11 of the membrane concentration equipment 10 is connected to the recovery tank inlet 21 of the recovery tank 20, and the recovery tank outlet 22 of the recovery tank 20 is connected to the condenser 30. Dialysis water can be used as a cold source to exchange heat with the hot fluid, and the hot fluid can be cooled and condensed. Compared with the technical solution of directly discharging dialysis water in related technologies, this system can not only realize the recovery and utilization of dialysis water, improve water resource utilization, and reduce wastewater treatment pressure, but also use dialysis water to replace the original cold source water of the condenser 30, thereby reducing water costs and contributing to sustainable development. In addition, it can reduce the energy consumption for producing soft water and save on the maintenance costs of soft water equipment.

[0028] Furthermore, since the dairy product membrane concentration process is intermittent, the production of dialysis water is also intermittent. By setting up a recovery tank 20, the dialysis water can be stored in the recovery tank 20. By setting up a recovery tank water level detection device 40 and a recovery tank pumping device 50, the recovery tank pumping device 50 can start and stop according to the water level detected by the recovery tank water level detection device 40. When the water level is high, the recovery tank pumping device 50 operates, delivering water to the condenser 30 to prevent the water level in the recovery tank 20 from overflowing due to excessively high water levels. When the water level is low, the recovery tank pumping device 50 stops operating to prevent the recovery tank pumping device 50 from running dry due to insufficient water supply, thus avoiding reduced service life and damage caused by dry running, effectively protecting the recovery tank pumping device 50. Therefore, through the cooperation of the recovery tank water level detection device 40 and the recovery tank pumping device 50, the water level in the recovery tank 20 can be controlled within a reasonable range, facilitating the continuous, efficient, and stable operation of the dairy product dialysis water recovery system 1.

[0029] Therefore, the dairy dialysis water recycling system 1 according to the present invention has the advantages of high water resource utilization, reduced water cost, and continuous and stable operation.

[0030] The following description, with reference to the accompanying drawings, describes a specific embodiment of a dairy product dialysis water recovery system 1 according to the present invention.

[0031] In some specific embodiments of this utility model, such as Figure 1 As shown, the dairy product dialysis water recovery system 1 according to an embodiment of the present invention includes a membrane concentration device 10, a recovery tank 20, a condenser 30, a recovery tank water level detection device 40, and a recovery tank pumping device 50.

[0032] Specifically, such as Figure 1 As shown, the recovery tank water level detection device 40 includes a high water level detection device 41 and a low water level detection device 42. The recovery tank pumping device 50 operates when the high water level detection device 41 is triggered. The recovery tank pumping device 50 stops when the low water level detection device 42 is triggered. Specifically, the high water level detection device 41 is located above the low water level detection device 42 (the vertical direction is shown by the arrow in the figure). When the water level in the recovery tank 20 reaches the predetermined low water level, the low water level detection device 42 is triggered; when the water level in the recovery tank 20 reaches the predetermined high water level, the high water level detection device 41 is triggered. This allows different detection devices to be triggered when the water level in the recovery tank 20 is too high or too low, facilitating the detection of the water level in the recovery tank 20 and the control of the start and stop of the recovery tank pumping device 50, thus facilitating the control of the water level in the recovery tank 20.

[0033] More specifically, such as Figure 1 As shown, the recovery tank 20 is also equipped with a recovery tank discharge port 23, and a recovery tank discharge valve 24 is connected to the recovery tank discharge port 23. Specifically, the recovery tank discharge port 23 can be connected to the drainage system or directly discharged to the ground. This allows the recovery tank discharge valve 24 to be opened when needed to drain the water in the recovery tank 20, for example, when the condenser 30 has not been used for a long time, resulting in an excessively high water level in the recovery tank 20.

[0034] Figure 1 A dairy product dialysis water recovery system 1, according to some examples of the present invention, is shown. For example... Figure 1 As shown, the dairy dialysis water recovery system 1 also includes a buffer tank 60, the volume of which is smaller than that of the recovery tank 20. The buffer tank 60 is equipped with a buffer tank inlet 61 and a buffer tank outlet 62. The buffer tank inlet 61 is connected to the dialysis water outlet 11, and the buffer tank outlet 62 is connected to the recovery tank inlet 21. Since the concentration process of the membrane concentration device 10 is intermittent, the dialysis water is produced intermittently. The buffer tank 60 can buffer and store the water between the membrane concentration device 10 and the recovery tank 20, making the subsequent water supply more stable and orderly, preventing the pumping device from running dry, and ensuring the stable, efficient, and continuous operation of the dairy dialysis water recovery system 1.

[0035] Specifically, such as Figure 1As shown, the buffer tank 60 is also equipped with a buffer tank discharge port 65, which is connected to a buffer tank discharge valve 66. A buffer tank pumping device 67 is connected between the buffer tank outlet 62 and the recovery tank inlet 21. Specifically, the buffer tank discharge port 65 can be connected to a drainage system or directly discharged to the ground. This allows the buffer tank pumping device 67 to be turned on and the buffer tank discharge valve 66 to be closed when dialysis water needs to be recovered, so that the dialysis water can smoothly enter the recovery tank 20. When maintenance is required or water recovery is not needed, the buffer tank pumping device 67 can be turned off and the buffer tank discharge valve 66 can be opened to discharge the water in the buffer tank 60.

[0036] Advantageously, such as Figure 1 As shown, the buffer tank 60 is also equipped with a water quality detection device 70, which is electrically connected to the buffer tank discharge valve 66 and the buffer tank pumping device 67. This allows the water quality detection device 70 to monitor the water quality within the buffer tank 60. When the water quality is substandard, the buffer tank pumping device 67 shuts off and the buffer tank discharge valve 66 opens. This prevents substandard water from entering the recovery tank 20 and discharges the substandard water through the buffer tank discharge port 65. This further facilitates ensuring the water quality of the recovery tank 20 and the subsequently recycled dialysis water, improving the reliability of subsequent water use.

[0037] Optionally, such as Figure 1 As shown, the water quality testing device 70 includes a pH testing device 71 and a conductivity testing device 72. This allows the pH and conductivity of the water in the buffer tank 60 to be detected by the pH testing device 71 and the conductivity testing device 72, respectively. When the pH and conductivity of the water in the buffer tank 60 exceed a predetermined range, the water quality is deemed unqualified, and the recycling process is stopped promptly by shutting down the buffer tank pumping device 67 and opening the buffer tank discharge valve 66.

[0038] Specifically, the water quality testing device 70 is also connected to an alarm device to issue an alarm when the water quality testing device 70 detects that the water quality is substandard.

[0039] More specifically, such as Figure 1 As shown, the buffer tank 60 is equipped with a high water level detection device 63 and a low water level detection device 64, and the buffer tank pumping device 67 is electrically connected to the high water level detection device 63 and the low water level detection device 64 respectively.

[0040] More advantageously, such as Figure 1As shown, the condenser 30 has a hot fluid flow channel and a dialysis water flow channel. The dialysis water flow channel is adapted to exchange heat with the hot fluid flow channel. A water storage tank 31 is provided inside the condenser 30. The inlet of the water storage tank 31 is connected to the outlet 22 of the recovery tank, and the outlet of the water storage tank 31 is connected to the dialysis water flow channel. This facilitates heat exchange between the dialysis water and the hot fluid, facilitates cooling and condensation of the hot fluid, and allows for the storage of dialysis water in the water storage tank 31, enabling continuous heat exchange.

[0041] Figure 1 A dairy product dialysis water recovery system 1, according to some examples of the present invention, is shown. For example... Figure 1 As shown, the membrane concentration equipment 10 includes an inlet pipe 12, a dialysis water outlet pipe 15, and multiple membrane filtration devices 16. The inlet pipe 12 is connected to the milk source, and an inlet regulating valve 13 and a booster pump 14 are connected to the inlet pipe 12. A dialysis water outlet 11 is formed on the dialysis water outlet pipe 15. The inlet of each membrane filtration device 16 is connected to the inlet pipe 12, and the outlet is connected to the dialysis water outlet pipe 15. Each membrane filtration device 16 has a filter inlet valve 17 connected to its inlet and a filter outlet valve 18 connected to its outlet. Specifically, a cleaning agent can also be introduced into the inlet pipe 12 to facilitate cleaning of the membrane concentration equipment 10 when concentration filtration is not required. The membrane filtration devices 16 can be RO membrane filtration devices. Multiple membrane filtration devices 16 can be mounted on a filter membrane support 19. The inlet regulating valve 13 can adjust the inlet flow rate and control the timing of inlet injection through the inlet pipe 12. The booster pump 14 can ensure the pressure of the milk entering the membrane filter device 16, facilitating the filtration of the milk through the membrane filter device 16 and achieving a highly efficient concentration filtration process. Each filter inlet valve 17 and filter outlet valve 18 can independently control the on / off state and flow rate of its respective membrane filter device 16. Multiple membrane filter devices 16 can be shut down individually for maintenance while others maintain the filtration process, ensuring continuous production.

[0042] Specifically, such as Figure 1 As shown, the discharge port 23 of the recovery tank is located at the bottom of the recovery tank 20 for drainage, and the top of the recovery tank 20 is equipped with a recovery tank pressure balancing valve 25 to balance the internal and external air pressure during water inflow and outflow. The discharge port 65 of the buffer tank is located at the bottom of the buffer tank 60 for drainage, and the top of the buffer tank 60 is equipped with a buffer tank pressure balancing valve 68 to balance the internal and external air pressure during water inflow and outflow.

[0043] The recycling tank outlet 22 is connected to a recycling tank outlet on / off valve 26, which can be closed during maintenance to facilitate maintenance.
