Description

Technical Field

[0001] The present application relates to the technical field of high-temperature disinfection of water bodies, and in particular to a high-temperature disinfection system for water bodies. Background Art

[0002] High temperature disinfection is a common method in the disinfection and sterilization of water used in aquaculture tanks. Its principle is to use high temperature to kill microorganisms and pathogens in water. However, in practical applications, the sterilization effect of high temperature water is often affected by many factors, such as temperature, time, and water flow rate.

[0003] Traditional heating methods (such as electric heating rods and gas boilers) have problems with large temperature fluctuations and high thermal inertia. Studies have shown that when the water temperature drops to a critical value (such as below 65°C) due to heat loss, the sterilization efficiency decays exponentially (experimental data show that the sterilization rate at 65°C for 10 minutes is only 70%, while at 75°C it can reach 99.9% for the same time). It is difficult for existing systems to stably maintain the target temperature in flowing water, especially when the water flow rate is greater than 1.5m / s, the heat dissipation of the pipes is aggravated, resulting in the disinfection time being forced to be shortened, and the sterilization rate cannot meet industry standards. Summary of the invention

[0004] In order to increase the duration of high-temperature disinfection of water bodies and improve the sterilization rate of high-temperature water bodies, the present application provides a high-temperature disinfection system for water bodies.

[0005] The present application provides a water high temperature disinfection system, which adopts the following technical solution:

[0006] A high-temperature water disinfection system comprises a heater, an insulated water tank and a cooler, wherein a water inlet is arranged on a side of the insulated water tank close to the top, a water outlet is arranged on a side of the insulated water tank close to the bottom and away from the water inlet, the output end of the heater is connected with the water inlet of the insulated water tank through a pipe, the cooler is connected with the water outlet of the insulated water tank through a pipe, a plurality of partition plates are arranged in the insulated water tank, the plurality of partition plates are staggered respectively, and the plurality of partition plates enclose a curved diversion channel for water flow.

[0007] By adopting the above technical scheme, when high-temperature disinfection of the water body is required, the raw water is first input into the heater, the heated water body is input into the insulated water tank from the water inlet end, and then the water body flows along the curved diversion channel, and then is input into the cooler from the water outlet end for cooling, and the return water after cooling is finally output from the cooler to complete the high-temperature disinfection of the water body. Through the diversion effect of the curved diversion channel, the time the water body stays in the insulated water tank is extended, thereby increasing the high-temperature disinfection time of the water body, which is beneficial to improving the sterilization rate of the high-temperature water body.

[0008] Optionally, a heat exchanger is provided between the heat preservation water tank and the cooler. The heat exchanger includes a first input end, a first output end, a second input end, and a second output end. The first input end is communicated with the first output end, which is defined as a first channel; the second input end and the second output end are communicated, which is defined as a second channel. The first channel and the second channel are not communicated. The first input end of the heat exchanger is communicated with the raw water, the first output end of the heat exchanger is communicated with the input end of the heater, the water outlet end of the heat preservation water tank is communicated with the second input end of the heat exchanger, and the second output end of the heat exchanger is communicated with the input end of the cooler.

[0009] By adopting the above technical solution, when the water body is output from the water outlet pipe of the heat preservation water tank, the high-temperature water body is input into the second input end of the heat exchanger. When the raw water continuously inputs into the first input end of the heat exchanger, at this time, the high-temperature water body exchanges heat to the raw water, thereby preheating the raw water and reducing the heating power of the heater. At the same time, the temperature of the high-temperature water body decreases after heat exchange, thereby pre-cooling the return water and reducing the cooling power of the cooler. Furthermore, it is beneficial to reduce the power consumption of the equipment and improve the heating efficiency of the raw water and the cooling efficiency of the return water.

[0010] Optionally, the bent diversion channel includes a bottom channel. A first collection box is arranged on the bottom channel. Part of the partition plates are fixedly connected to the top surface of the first collection box. First water holes are respectively opened on both sides of the first collection box. Second water holes are penetrated through the side walls of part of the partition plates. A first sealing door for opening and closing the first water hole is slidably arranged on the inner wall of the first collection box. A second sealing door for opening and closing the second water hole is slidably arranged on the side wall of part of the partition plates. The first collection box is provided with an opening and closing mechanism for simultaneously driving the first sealing door and the second sealing door to move. A cleaning port is opened on the bottom surface of the heat preservation water tank. A folding bag is arranged at the cleaning port. A first filter screen is arranged at the first water hole far from the water inlet end of the heat preservation water tank.

[0011] By adopting the above technical solution, sediment impurities are easily deposited at the bottom of the box. By opening the first sealing door and closing the second sealing door through the opening and closing mechanism, under the action of the first filter screen, the sediment impurities are collected in the first collection box from the first water hole along with the water flow. When it is necessary to clean the sediment impurities in the first collection box, by closing the first sealing door and opening the second sealing door through the opening and closing mechanism, at this time, the water body keeps flowing through the second water hole, and the first collection box is in a sealed space. Then, the folding filter bag is opened from the bottom of the heat preservation water tank. The water body and sediment impurities in the first collection box are first collected in the folding filter bag, and finally, the sediment impurities in the folding filter bag are cleaned. This process is beneficial to avoid the water body in the first collection box splashing outside when the folding bag is opened, and at the same time, it is beneficial to improve the convenience of cleaning the sediment impurities deposited in the first collection box.

[0012] Optionally, the opening and closing mechanism includes an adjusting rod. A fixed seat is provided on the inner top wall of the first collection box. The adjusting rod is slidably connected to the fixed seat. On both sides of one end of the adjusting rod, first connecting frames are respectively provided. The first connecting frames are connected to the top surface of the first sealing door. On the top surface of the first connecting frame, a second connecting frame is provided. The second connecting frame is connected to the bottom surface of the second sealing door. The fixed seat is provided with a control component for driving the adjusting rod to lift and lower.

[0013] By adopting the above technical solution, when the adjusting rod is driven to descend by the control component, the adjusting rod simultaneously drives the first connecting frame and the second connecting frame to descend. The first connecting frame drives the first sealing door to descend, thereby closing the first water hole. The second connecting frame drives the second sealing door to descend, thereby opening the second water hole, ensuring that the water body continuously flows in the heat preservation water tank during the cleaning of sediment impurities, and improving the convenience of impurity cleaning.

[0014] Optionally, the control component includes a pressing rod. The pressing rod is horizontally slidably arranged in the fixed seat. One end of the pressing rod is provided with a first wedge surface. The top end of the adjusting rod is provided with a second wedge surface. The first wedge surface and the second wedge surface cooperate with each other. A vertical groove for the adjusting rod to lift and lower is opened in the fixed seat. A spring is sleeved on the side wall of the adjusting rod. One end of the spring is fixedly connected to the side wall of the adjusting rod, and the other end of the spring is fixedly connected to the groove wall of the vertical groove. The heat preservation water tank is provided with a fixing member for locking the pressing rod.

[0015] By adopting the above technical solution, when the pressing rod is pressed, under the cooperation of the first wedge surface and the second wedge surface, the pressing rod drives the adjusting rod to descend. The adjusting rod compresses the spring, and the adjusting rod simultaneously drives the first connecting frame and the second connecting frame to descend. When the pressing rod is released, the spring releases elastic force and drives the adjusting rod to rise. Similarly, under the cooperation of the first wedge surface and the second wedge surface, the adjusting rod drives the pressing rod to reset and extend outwards, which is beneficial to controlling the stability of the opening and closing of the first sealing door and the second sealing door.

[0016] Optionally, the fixing member is a screw sleeve. A screw cylinder is provided on the side wall of the heat preservation water tank. One end of the pressing rod extends outside the screw cylinder. The screw sleeve is rotatably sleeved on one end of the pressing rod. The screw sleeve is threadedly connected to the screw cylinder.

[0017] By adopting the above technical solution, when the pressing rod is pressed and the position of the pressing rod needs to be fixed, the screw sleeve is rotated. At this time, the screw sleeve is threadedly connected to the screw cylinder, and the pressing rod is fixed at the current position. When the locking of the pressing rod needs to be released, the screw sleeve is loosened by screwing, so that the screw sleeve and the screw cylinder are separated from each other. At this time, the pressing rod is unlocked, which is beneficial to improving the stability of controlling the opening and closing of the first sealing door and the second sealing door in the current state.

[0018] Optionally, the folding pocket includes a folding portion and a flat portion. One end of the folding portion is fixedly connected to the flat portion, and the other end of the folding portion is fixedly connected to the inner wall of the cleaning port. A drain cover is communicated with the side wall of the folding portion. The flat portion is inserted into the cleaning port, and the heat preservation water tank is provided with a locking member for locking the flat portion.

[0019] By adopting the above technical solution, when the locking of the locking member is released, the flat portion is pulled, and the flat portion drives the folding cloth to unfold. At this time, the water body in the first collection box is collected in the unfolded folding pocket. Then, the drain cover is opened to discharge the water body and sediment impurities in the folding pocket, achieving the purpose of cleaning the sediment impurities and improving the stability of sediment impurity cleaning.

[0020] Optionally, a second collection box is provided on the side wall of the heat preservation water tank. A collection port is opened inside the second collection box. The second collection box is communicated with the heat preservation water tank through the collection port. A second filter screen is arranged in the second collection box, and a drain pipe is arranged at the bottom surface of the second collection box. The other end of the drain pipe is fixedly communicated with the heat preservation water tank.

[0021] By adopting the above technical solution, there are floating impurities in the water body. The floating impurities are collected on the second filter screen in the second collection box through the collection port, and then the water body flows back into the heat preservation water tank through the drain pipe, which is beneficial to improving the stability of floating impurity cleaning.

[0022] Optionally, the top surface of the second collection box is open, and a top cover is provided at the open end of the second collection box.

[0023] By adopting the above technical solution, when it is necessary to clean the impurities on the second filter screen, the top cover is opened, and then the second filter screen is taken out for cleaning, which is beneficial to improving the convenience of floating impurity cleaning.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. When high-temperature disinfection of the water body is required, the raw water is first input into the heater. The heated water body is input into the heat preservation water tank from the water inlet end, and then the water body flows along the bent diversion channel, and then is input into the cooler from the water outlet end for cooling. The return water after cooling finally outputs from the cooler, completing the high-temperature disinfection of the water body. Under the diversion of the bent diversion channel, the time of the water body in the heat preservation water tank is extended, thereby increasing the high-temperature disinfection time of the water body, which is beneficial to improving the sterilization rate of the high-temperature water body;

[0026] 2. The precipitated impurities tend to sink to the bottom of the tank. By operating the opening and closing mechanism to open the first sealing door and close the second sealing door, under the action of the first filter screen, the precipitated impurities are collected in the first collection tank through the first water holes along with the flowing water. When it is necessary to clean the precipitated impurities in the first collection tank, the first sealing door is closed and the second sealing door is opened through the opening and closing mechanism. At this time, the water body keeps flowing through the second water holes, while the first collection tank is in a sealed space. Then, the folding filter bag is opened from the bottom of the heat preservation water tank, and the water body and precipitated impurities in the first collection tank are first collected in the folding filter bag, and finally the precipitated impurities in the folding filter bag are cleaned. This process helps to prevent the water body in the first collection tank from splashing out when the folding bag is opened, and also helps to improve the convenience of cleaning the precipitated impurities in the first collection tank;

[0027] 3. There are floating impurities in the water body. The floating impurities are collected on the second filter screen in the second collection tank through the collection port, and then the water body flows back into the heat preservation water tank through the drain pipe, which helps to improve the stability of cleaning the floating impurities.

DETAILED DESCRIPTION

[0036] The following is combined with Figures 1-7 This application is described in further detail.

[0037] See also Figure 1 A high-temperature water disinfection system includes a heater 1, an insulated water tank 2 and a cooler 3. The insulated water tank 2 includes a water inlet and a water outlet. The water inlet is arranged on a side of the insulated water tank 2 close to the top, and the water outlet is arranged on a side of the insulated water tank 2 close to the bottom and away from the water inlet. In this embodiment, the heater 1 is a heat pump condenser, the cooler 3 is a heat pump evaporator, and a heat pump main unit 4 is connected between the heat pump condenser and the heat pump evaporator. The output end of the heater 1 is fixedly connected to the water inlet of the insulated water tank 2 through a pipeline, and the cooler 3 is fixedly connected to the water outlet of the insulated water tank 2 through a pipeline. A partition plate 5 is fixedly connected inside the insulated water tank 2, and a plurality of partition plates 5 are provided. The plurality of partition plates 5 are staggered and arranged respectively, and the plurality of partition plates 5 enclose a curved diversion channel 6 for the flow of water.

[0038] The heater 1 and the cooler 3 are fixedly connected to the heat pump host 4 through pipelines respectively. The heat pump host 4 is used to supply refrigerant to the heater 1 and the cooler 3 for heating and cooling the water body.

[0039] In addition, see Figure 1 , a heat exchanger 7 is also fixedly connected between the insulated water tank 2 and the cooler 3, and the heat exchanger 7 includes a first input end, a first output end, a second input end and a second output end. The first input end is connected to the first output end, which is defined as a first channel; the second input end is connected to the second output end, which is defined as a second channel, and the first channel and the second channel are not connected. Among them, the first input end of the heat exchanger 7 is connected to the raw water, and the first output end of the heat exchanger 7 is fixedly connected to the input end of the heater 1 through a pipeline. The water outlet end of the insulated water tank 2 is fixedly connected to the second input end of the heat exchanger 7 through a pipeline, and the second output end of the heat exchanger 7 is fixedly connected to the input end of the cooler 3 through a pipeline.

[0040] When high-temperature disinfection of raw water is required, first start the heater 1, cooler 3 and heat pump main unit 4, and then input the raw water into the first input end of the heat exchanger 7, and the initial temperature value of the raw water is 27°C. As the equipment continues to operate, the water body is finally heated to 75°C under the heating of the heater 1, and then input into the heat preservation water tank 2. At this time, the water body flows along the bent diversion channel 6, extending the flow trajectory of the water body, and under the action of high temperature, the pathogens in the water body are sterilized. Then the water body is output from the water outlet end of the heat preservation water tank 2. At this time, the water temperature is 72°C. As the heat dissipates during pipeline flow, when the water body is input into the second input end of the heat exchanger 7, the temperature is 70°C. Under the water-water heat exchange of the heat exchanger 7, the recovered temperature output from the second output end of the heat exchanger 7 is 37°C. Then, the cooler 3 is used to cool the return water to the use temperature of 27°C to complete the high-temperature disinfection of the water body.

[0041] It should be noted that during long-term operation, the heat exchanger 7 preheats the raw water to 60°C through water-water heat exchange, and the heater 1 heats the 60°C water body to 75°C. In this process, the return water temperature output from the water outlet end of the heat preservation water tank 2 is used for water-water heat exchange, so as to preheat the raw water, which not only reduces the power consumption of the heater 1, but also improves the heating efficiency of the water body. Similarly, the cooler 3 is the same. By pre-cooling the temperature of the return water through water-water heat exchange, the power consumption of the cooler 3 is reduced, and the cooling efficiency of the water body is improved.

[0042] See Figure 2 and Figure 3 As shown in and, the bent diversion channel 6 includes a bottom channel 8, and the bottom channel 8 is located between some partition plates 5 and the inner bottom wall of the heat preservation water tank 2. The bottom channel 8 is fixedly connected with a first collection box 9, and some partition plates 5 are fixedly connected with the top surface of the first collection box 9. First water holes 10 are respectively opened on both sides of the first collection box 9, and a first filter screen 11 is fixedly connected to the first water hole 10 far from the water inlet end of the heat preservation water tank 2. Second water holes 13 penetrate through the surface of some partition plates 5. A first sealing door 12 is slidably installed on the inner wall of the first collection box 9, and the first sealing door 12 is used to open and close the first water hole 10. A second sealing door 14 is slidably installed on the side wall of some partition plates 5, and the second sealing door 14 is used to open and close the second water hole 13. The first collection box 9 is also provided with an opening and closing mechanism, and the opening and closing mechanism is used to drive the first sealing door 12 and the second sealing door 14 to open and close simultaneously. A cleaning port 15 is opened on the bottom surface of the heat preservation water tank 2, and the cleaning port 15 is communicated with the inside of the first collection box 9. A folding bag 16 is installed in the cleaning port 15.

[0043] The raw water in this embodiment is mainly used for aquaculture. In aquaculture, the raw water contains sediment impurities. After the water body is input into the heat preservation water tank 2, the sediment impurities settle in the bottom channel 8 along with the flow of the water body. Under the action of the first filter screen 11, the sediment impurities are input from the first water hole 10 and collected in the first collection box 9.

[0044] When it is necessary to clean the sediment impurities in the first collection box 9, the first sealing door 12 is closed and the second sealing door 14 is opened through the opening and closing mechanism. At this time, the water body keeps flowing through the second water hole 13, while the first collection box 9 is in a sealed space. Then, the folding filter bag is opened from the bottom of the heat preservation water tank 2. The water body and sediment impurities in the first collection box 9 first converge in the folding filter bag, and finally the sediment impurities in the folding filter bag are cleaned.

[0045] Specifically, referring to Figures 3-5 , the opening and closing mechanism includes an adjusting rod 17. A fixed seat 18 is fixedly connected to the inner top wall of the first collection box 9. The cross-section of the adjusting rod 17 is U-shaped, and the adjusting rod 17 is slidably connected to the fixed seat 18. First connecting frames 19 are respectively fixedly connected to both sides of one end of the adjusting rod 17, and the first connecting frames 19 are fixedly connected to the top surface of the first sealing door 12. A second connecting frame 20 is also fixedly connected to the top surface of the first connecting frame 19. The second connecting frame 20 extends outside the first collection box 9, and the second connecting frame 20 is fixedly connected to the bottom surface of the second sealing door 14.

[0046] In addition, a control component is also installed on the fixed seat 18. The control component includes a pressing rod 21. The pressing rod 21 is horizontally slidably installed in the fixed seat 18. A first wedge surface 22 is provided at one end of the pressing rod 21, and the top end of the adjusting rod 17 is set as a second wedge surface 23. The first wedge surface 22 and the second wedge surface 23 cooperate with each other. A vertical groove 24 is opened in the fixed seat 18, and the adjusting rod 17 slides up and down in the vertical groove 24. A spring 25 is sleeved on the side wall of the adjusting rod 17. One end of the spring 25 is fixedly connected to the side wall of the adjusting rod 17, and the other end of the spring 25 of the adjusting rod 17 is fixedly connected to the groove wall of the vertical groove 24.

[0047] At the same time, a fixing member is also installed on the heat preservation water tank 2. The fixing member is a screw sleeve 26. A screw cylinder 27 is fixedly connected to the side wall of the heat preservation water tank 2. One end of the pressing rod 21 extends outside the fixed seat 18 and the screw cylinder 27 in sequence. The screw sleeve 26 is rotatably installed at one end of the pressing rod 21, and the screw sleeve 26 is threadedly connected to the screw cylinder 27.

[0048] Before the sediment impurities in the first collection box 9 need to be cleaned, the first water holes 10 on both sides of the first collection box 9 need to be closed, and the second water holes 13 need to be opened at the same time to ensure that the water body flows normally in the thermal insulation water tank 2 and is sterilized at high temperature. At this time, the pressing rod 21 is pressed first. Under the cooperation of the first wedge surface 22 and the second wedge surface 23, the pressing rod 21 drives the adjusting rod 17 to descend, and the adjusting rod 17 drives the first sealing door 12 to descend through the first connecting frame 19, and seals and closes the first water hole 10. The adjusting rod 17 drives the second sealing door 14 to descend through the second connecting frame 20, and opens the second water hole 13 for circulation. When the adjusting rod 17 descends, it also squeezes the spring 25, and then the screw sleeve 26 is threadedly rotated, and the screw sleeve 26 is threadedly connected with the screw barrel 27, and the pressing rod 21 is fixed in the current pressing state. Finally, the interior of the first collection box 9 is isolated from the interior of the thermal insulation water tank 2, so as to facilitate the subsequent cleaning of the sediment impurities inside the first collection box 9.

[0049] See also Figure 3 and Figure 6 The folding pocket 16 includes a folding portion 28 and a plane portion 29. The folding portion 28 is made of waterproof fabric. One end of the folding portion 28 is fixedly connected to the wall of the cleaning port 15, and the other end of the folding portion 28 is fixedly connected to the plane portion 29.

The thermal insulation water tank 2 is also equipped with a lock 31, which is a common lock core structure.

[0050] When it is necessary to clean the precipitated impurities in the first collecting box 9, the lock 31 is opened, and the plane portion 29 is pulled downward, and the plane portion 29 drives the folding portion 28 to unfold, and the precipitated impurities in the first collecting box 9 are gathered in the unfolded folding portion 28. Finally, after the drain cover 30 is opened, the precipitated impurities are discharged to the outside, thereby achieving the purpose of cleaning the precipitated impurities.

[0051] See also Figure 2 and Figure 7 In order to facilitate the cleaning of floating impurities in the water body, a second collecting box 32 is fixedly connected to the side wall of the insulated water tank 2, and the number of the second collecting boxes 32 is at least two. A collecting port 33 is provided on the inner side of the second collecting box 32, and the second collecting box 32 is connected to the insulated water tank 2 through the collecting port 33. It is worth noting that the collecting port 33 is slightly lower than the liquid level in the insulated water tank 2. A second filter screen 34 is also embedded in the second collecting box 32, and a drain pipe 35 is fixedly connected to the bottom surface of the second collecting box 32, and the other end of the drain pipe 35 is fixedly connected to the insulated water tank 2. In addition, the drain pipe 35 is also fixedly connected to a one-way valve and a small water pump.

[0052] The floating objects in the water body are collected into the second collection box 32 through the collection port 33, and the impurities are filtered by the second filter screen 34. Then, start the small water pump, and the water body flows back into the heat preservation water tank 2 through the one-way valve. Repeat this process to achieve the purpose of cleaning floating impurities.

[0053] It should be noted that when participating Figure 7 , the top surface of the second collection box 32 is open, and a top cover 36 is provided at the open end of the second collection box 32.

[0054] By opening the top cover 36, the floating impurities on the second filter screen 34 can be cleaned, improving the convenience of cleaning the impurities on the second filter screen 34.

[0055] The working principle of a water body high-temperature disinfection system:

[0056] When high-temperature disinfection of raw water is required, first start the heater 1, cooler 3, and heat pump host 4, and then input the raw water into the first input end of the heat exchanger 7, and the initial temperature value of the raw water is 27°C. With the continuous operation of each device, the water body is finally heated to 75°C under the heating of the heater 1, and then input into the heat preservation water tank 2. At this time, the water body flows along the bent diversion channel 6, extending the flow trajectory of the water body, and under the action of high temperature, the pathogens in the water body are sterilized. Then the water body is output from the water outlet end of the heat preservation water tank 2. At this time, the water temperature is 72°C. With the heat dissipation of the water flowing through the pipeline, when the water body is input into the second input end of the heat exchanger 7, the temperature is 70°C. Under the water-water heat exchange of the heat exchanger 7, the recovered temperature output from the second output end of the heat exchanger 7 is 37°C. Then, the cooler 3 cools the return water to the use temperature of 27°C to complete the high-temperature disinfection of the water body.

[0057] It should be noted that during the long-term operation process, the heat exchanger 7 preheats the raw water to 60°C through water-water heat exchange, and the heater 1 heats the 60°C water body to 75°C. In this process, the return water temperature output from the water outlet end of the heat preservation water tank 2 is used for water-water heat exchange, so as to preheat the raw water, which not only reduces the power consumption of the heater 1, but also improves the heating efficiency of the water body. Similarly, the cooler 3 is also the same. By pre-cooling the return water through water-water heat exchange, the power consumption of the cooler 3 is reduced, and the cooling efficiency of the water body is improved.

[0058] In summary, under the guiding action of the bent diversion channel 6, the duration of the water body in the heat preservation water tank 2 is extended, thereby increasing the high-temperature disinfection duration of the water body, and further facilitating the improvement of the sterilization rate of the high-temperature water body.

[0059] The above are all the preferred embodiments of this application. The protection scope of this application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
