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: 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.

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.

[0007] Optionally, a heat exchanger is arranged between the insulated water tank and the cooler, and the heat exchanger includes a first input end, a first output end, a second input end and a second output end.

DETAILED DESCRIPTION

[0026] The following is combined with Figure 1-7 This application is described in further detail.

[0027] 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.

[0028] 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.

[0029] 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.

[0030] When it is necessary to disinfect the raw water at high temperature, first start the heater 1, the cooler 3 and the 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 of the raw water is 27°C. With the continuous operation of each device, the water body is finally raised to 75°C under the heating effect of the heater 1, and then input into the insulated water tank 2. At this time, the water body flows along the curved diversion channel 6, extending the flow trajectory of the water body, and sterilizing the pathogens in the water body under the action of high temperature. Then the water body is output from the water outlet of the insulated water tank 2, and the water body temperature is 72°C. As the heat of the pipeline flow is dissipated, the water body is input into the second input end of the heat exchanger 7, and the temperature is 70°C. Under the water-to-water heat exchange effect of the heat exchanger 7, the recovery temperature output from the second output end of the heat exchanger 7 is 37°C. Then the return water is cooled to the use temperature of 27°C through the cooler 3 to complete the high-temperature disinfection of the water body.

[0031] It is worth noting that during long-term operation, the heat exchanger 7 preheats the raw water to 60°C through water-to-water heat exchange, and the heater 1 heats the 60°C water to 75°C. In this process, the return water temperature output from the outlet of the insulated water tank 2 is used for water-to-water heat exchange, so that the raw water is preheated, which not only reduces the power consumption of the heater 1, but also improves the heating efficiency of the water. Similarly, the cooler 3 also reduces the temperature of the return water through water-to-water heat exchange, reduces the power consumption of the cooler 3, and improves the cooling efficiency of the water.

[0032] See also Figure 2 and Figure 3 , the curved flow guide channel 6 includes a bottom channel 8, which is located between the part of the partition plate 5 and the inner bottom wall of the insulated water tank 2. The bottom channel 8 is fixedly connected to the first collecting box 9, and the part of the partition plate 5 is fixedly connected to the top surface of the first collecting box 9.

The first collecting box 9 is also equipped with an opening and closing mechanism, which is used to drive the first sealing door 12 and the second sealing door 14 to open and close at the same time. The bottom surface of the insulated water tank 2 is provided with a cleaning port 15, and the cleaning port 15 is connected to the inside of the first collecting box 9. A folding pocket 16 is installed in the cleaning port 15.

[0033] The raw water in this embodiment is mainly used for aquaculture, in which the raw water contains precipitated impurities. After the water is input into the thermal insulation water tank 2, the precipitated impurities are settled in the bottom channel 8 along with the flow of the water, and under the action of the first filter screen 11, the precipitated impurities are input from the first water hole 10 and collected in the first collection box 9.

[0034] When it is necessary to clean the precipitated impurities in the first collecting 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, and the first collecting box 9 is in a sealed space. Then the folding filter bag is opened from the bottom of the insulated water tank 2, and the water body and the precipitated impurities in the first collecting box 9 are first gathered in the folded filter bag, and finally the precipitated impurities in the folded filter bag are cleaned.

[0035] For details, see Figure 3-Figure 5 The opening and closing mechanism includes an adjusting rod 17, and a fixing seat 18 is fixedly connected to the inner top wall of the first collection box 9.

[0036] In addition, the fixed seat 18 is also equipped with a control component, which includes a pressing rod 21, which is horizontally slidably installed in the fixed seat 18, and one end of the pressing rod 21 is provided with a first wedge surface 22, and the top end of the adjusting rod 17 is provided with a second wedge surface 23, and the first wedge surface 22 and the second wedge surface 23 cooperate with each other.

[0037] At the same time, the thermal insulation water tank 2 is also equipped with a fixing member, which is a screw sleeve 26. The side wall of the thermal insulation water tank 2 is fixedly connected with a screw barrel 27, and one end of the pressing rod 21 extends out of the fixing seat 18 and the screw barrel 27 in sequence. The screw sleeve 26 is rotatably installed on one end of the pressing rod 21, and the screw sleeve 26 is threadedly connected to the screw barrel 27.

[0038] 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.

[0040] 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.

[0041] 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.

[0042] Floating objects in the water are collected in the second collection box 32 through the collection port 33, and the impurities are filtered through the second filter screen 34. Then the small water pump is started, and the water flows back into the insulation water tank 2 through the one-way valve. This is repeated to achieve the purpose of cleaning floating impurities.

[0045] Working principle of a water high temperature disinfection system: When it is necessary to disinfect the raw water at high temperature, first start the heater 1, the cooler 3 and the 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 of the raw water is 27°C. With the continuous operation of each device, the water body is finally raised to 75°C under the heating effect of the heater 1, and then input into the insulated water tank 2. At this time, the water body flows along the curved diversion channel 6, extending the flow trajectory of the water body, and sterilizing the pathogens in the water body under the action of high temperature. Then the water body is output from the water outlet of the insulated water tank 2, and the water body temperature is 72°C. As the heat of the pipeline flow is dissipated, the water body is input into the second input end of the heat exchanger 7, and the temperature is 70°C. Under the water-to-water heat exchange effect of the heat exchanger 7, the recovery temperature output from the second output end of the heat exchanger 7 is 37°C. Then the return water is cooled to the use temperature of 27°C through the cooler 3 to complete the high-temperature disinfection of the water body.

[0046] It is worth noting that during long-term operation, the heat exchanger 7 preheats the raw water to 60°C through water-to-water heat exchange, and the heater 1 heats the 60°C water to 75°C. In this process, the return water temperature output from the outlet of the insulated water tank 2 is used for water-to-water heat exchange, so that the raw water is preheated, which not only reduces the power consumption of the heater 1, but also improves the heating efficiency of the water. Similarly, the cooler 3 also reduces the temperature of the return water through water-to-water heat exchange, reduces the power consumption of the cooler 3, and improves the cooling efficiency of the water.

[0047] In summary, the diversion effect of the curved diversion channel 6 prolongs the time the water stays in the insulated water tank 2, thereby increasing the high-temperature disinfection time of the water, which is beneficial to improving the sterilization rate of the high-temperature water.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
