Abstract
Description
Technical Field
[0001] This utility model relates to the field of renewable energy technology, and in particular to a system for the coordinated utilization of air and wastewater sources in shrimp farms. Background Technology
[0002] Currently, using electric heating rods to heat the water and maintain the water temperature in shrimp farming areas is a common temperature control method. However, this method has many problems:
[0003] (1) When electric heating rods are immersed in water for a long time, the high concentration of chloride ions in seawater will corrode the metal shell of the heating rods. The corroded substances will fall off and pollute the water, affecting the water quality. Heating rods with coatings (such as electroplating) on the surface will release heavy metals when the coatings dissolve, which will harm the health of the shrimp. The growth environment of sea shrimp has high requirements for water quality, so the water in the sea shrimp farming area needs to be changed frequently.
[0004] (2) Electric heating rods will also form scale when immersed in water for a long time, which will affect the energy conversion efficiency of the electric heating rods.
[0005] (3) The suitable water temperature for shrimp is usually 22-30℃. If the natural water temperature in the breeding area is low (such as in winter or high latitude areas), it needs to be heated continuously for 24 hours, which results in high long-term operating costs.
[0006] (4) There is a risk of electric leakage. The heating rod is in direct contact with the water (usually seawater, which has high conductivity). If the insulation layer is aged, damaged, or the wiring is not properly sealed, electric leakage is very likely to occur. This can lead to stress and death of shrimp (electric current stimulation) or even endanger the safety of operators.
[0007] Therefore, there is an urgent need to find a water heating system for shrimp farming that can replace heating rods, avoid metal ion precipitation and structural problems, improve water quality stability, reduce water change frequency, improve system safety, reduce operating costs, and ensure healthy shrimp farming.

[0032] The present invention will now be described in further detail with reference to the accompanying drawings:
[0033] like Figure 1 As shown, the present invention provides a shrimp farm air source and sewage source co-utilization system, including: a shrimp farming area 5, a water heating subsystem provided in the shrimp farming area 5, the water heating subsystem including a water heating pipe, the hot water in the water heating pipe heats the water in the shrimp farming area 5 to maintain the water temperature in the shrimp farming area 5 constant, and both ends of the water heating pipe are connected to tee fittings, which can be Y-type or T-type tee fittings;
[0034] The shrimp farming area 5 is equipped with an outlet and an inlet for replacing the water in the shrimp farming area 5. The outlet of the shrimp farming area 5 is connected to the inlet of the sewage tank 2. A sewage submersible pump 10 is installed on the pipeline between the outlet of the shrimp farming area 5 and the inlet of the sewage tank 2. The outlet of the sewage tank 2 is connected to the inlet of the sewage source heat pump unit 4A, and the outlet of the sewage source heat pump unit 4A is connected to the external drain outlet 18. When it is necessary to replace the water in the shrimp farming area 5, the shrimp farming area 5 must first be drained. At this time, the sewage submersible pump 10 is turned on to connect the sewage tank 2 with the water in the shrimp farming area 5, and the water in the shrimp farming area 5 is discharged into the sewage tank 2. After the water is drained, the sewage submersible pump 10 is turned off. Then, the shrimp farming area 5 is refilled. At this time, the submersible pump of the water storage tank 6 is turned on to connect the water storage tank 6 with the water in the shrimp farming area 5, and the water in the water storage tank 6 is added into the shrimp farming area 5 to replace the water.
[0035] Both ends of the water heating pipeline are connected to the inlet and outlet pipelines on side 4B of the sewage source heat pump unit via tee fittings, and both connecting pipelines are equipped with valves, such as... Figure 1 , 3 As shown, valves 15 and 16 are the fourth valve and the fifth valve, respectively. A sewage source water pump 7 is installed on the pipeline between the sewage tank 2 and the inlet of the sewage source heat pump unit 4A. The outlet of the sewage source heat pump unit 4A is connected to the external drain outlet 18. The inlet of the water heating pipeline is connected to a tee fitting, and a terminal circulating water pump 11 is installed on this pipeline. When the water in the shrimp farming area 5 has just been replaced, the sewage source heat pump unit 4 is started, such as... Figure 3 As shown, turn on the sewage source water pump 7, connect the sewage tank 2, the anti-blocking machine 3 and the sewage source heat pump unit 4. The sewage source heat pump unit 4 collects the waste heat in the sewage and discharges the sewage after the waste heat is collected through the outlet on side A. After the collection is completed, turn off the sewage source water pump 7. Then, open the fourth valve 15 and the fifth valve 16 between the outlet and inlet on side B of the sewage source heat pump unit 4 and the three-way fittings at both ends of the water heating pipeline, and turn on the end-side circulating water pump 11 to form a closed loop pipeline between the sewage source heat pump unit 4 and the water heating pipeline. At this time, the sewage source heat pump unit 4 releases the collected waste heat to heat the water in the closed loop pipeline and maintain the water temperature of the shrimp farming area 5 unchanged.
[0036] The water heating pipes are also connected at both ends to the inlet and outlet water outlets of the air source heat pump unit 1 via tee fittings, and both connecting pipes are equipped with valves, such as... Figure 1 , 2 As shown, these are the second valve 13 and the third valve 14, respectively. When the water in the shrimp farming area 5 is not changed, the air source heat pump unit 1 is started, and the second valve 13 and the third valve 14 between the inlet and outlet of the air source heat pump unit 1 and the two ends of the water heating pipeline are opened, as shown. Figure 2As shown, at this time, the air source heat pump unit 1 is connected to the water heating pipeline of the shrimp farming area 5 to form a closed loop pipeline. The air source heat pump unit 1 releases the stored air energy to heat the water in the closed loop pipeline and maintain the water temperature of the shrimp farming area 5 unchanged.
[0037] The remaining interfaces of the inlet and outlet tee fittings of the air source heat pump unit 1 are connected to the inlet of the water storage tank 6 and the tap water inlet 17, respectively. A valve is installed on the connecting pipe between the outlet tee fitting of the air source heat pump unit 1 and the inlet of the water storage tank 6. Figure 1 , 4 As shown, the first valve 12 is installed on the pipeline between the tap water inlet 17 and the tee fitting at the inlet of the air source heat pump unit 1. After water is added to the shrimp farming area 5 from the water storage tank 6, the water storage tank 6 needs to be replenished. When replenishing the water storage tank 6, if... Figure 4 As shown, turn on the submersible water pump 8, open the valve between the inlet of the water storage tank 6 and the outlet of the air source heat pump unit 1, and keep both valves between the three-way components at both ends of the inlet and outlet of the air source heat pump unit 1 and the three-way components at both ends of the water heating pipe closed, so that the tap water flows into the air source heat pump unit 1 from the tap water inlet 17, the air source heat pump unit 1 releases energy to heat the tap water, and the heated tap water enters the water storage tank 6.
[0038] In this utility model, the sewage source heat pump unit 4 includes an evaporator and a condenser. The evaporator absorbs heat from the water source and converts the refrigerant into a gaseous state. The gaseous refrigerant enters the condenser, where it releases heat to the heat dissipation medium. The heat dissipation medium absorbs the heat and its temperature rises.
[0039] In this utility model, an anti-blocking device 3 is provided on the pipeline between the sewage tank 2 and the inlet of the sewage source heat pump unit 4A to prevent foreign objects in the sewage tank 2 from blocking the channel.
[0040] In this utility model, a sewage source water pump 7 is installed on the pipeline between the sewage tank 2 and the water inlet on the A side of the sewage source heat pump unit 4A. The sewage source water pump 7 pumps the sewage in the sewage tank 2 into the sewage source heat pump unit 4 for waste heat recovery.
[0041] In this utility model, a sewage submersible pump 10 is installed on the pipeline between the outlet of the shrimp farming area 5 and the inlet of the sewage tank 2. The sewage submersible pump 10 pumps the water in the sewage tank 2 into the sewage tank 2 for temporary storage.
[0042] In this invention, the inlet end of the water heating pipeline is connected to a tee fitting, and the pipeline is equipped with a terminal circulating water pump 11. When the second valve 13 and the third valve 14 are open, the terminal circulating water pump 11 realizes the circulation of water between the air source heat pump unit 1 and the water heating pipeline, heating the water in the shrimp farming area 5 and maintaining a constant temperature. When the fourth valve 15 and the fifth valve 16 are open, the terminal circulating water pump 11 realizes the circulation of water between the sewage source heat pump unit 4 and the water heating pipeline, heating the water in the shrimp farming area 5 and maintaining a constant temperature.
[0043] In this utility model, a submersible water pump 8 is installed on the pipeline between the tap water inlet 17 and the tee fitting at the water inlet of the air source heat pump unit 1. The submersible water pump 8 pumps the tap water connected to the tap water inlet 17 to the air source heat pump unit 1 to heat the tap water.
[0044] In this utility model, a submersible pump for the water storage tank 6 is installed on the pipeline between the outlet of the water storage tank 6 and the inlet of the shrimp farming area 5. When the water in the shrimp farming area 5 is changed, the submersible pump for the water storage tank 6 pumps the heated water from the water storage tank 6 to the shrimp farming area 5.
[0045] In this invention, the water heating pipes in the shrimp farming area 5 are made of PE material, which is non-corrosive, does not form scale, and does not pollute the water, thereby improving water quality stability and reducing the frequency of water changes.
[0046] Example:
[0047] like Figure 1 As shown, in this system, air-source heat pump unit 1 and wastewater-source heat pump unit 4 work together to maintain the water temperature in the shrimp farming area 5. The principle of air-source heat pump unit 1 is: by consuming a small amount of electrical energy, it absorbs heat from the air and transfers it to the space or water requiring heating or warming. The principle of wastewater-source heat pump unit 4 is: the evaporator absorbs heat from the water source, converting the refrigerant into a gaseous state. The gaseous refrigerant enters the condenser, where it releases heat to the heat dissipation medium, causing the medium to absorb heat and its temperature to rise. The specific application methods and processes of this system include:
[0048] When the water in shrimp farming area 5 is not changed, start air source heat pump unit 1 and open the valves between the inlet and outlet of air source heat pump unit 1 and both ends of the water heating pipeline. Figure 2 As shown, at this time, the air source heat pump unit 1 is connected to the water heating pipeline of the shrimp farming area 5 to form a closed loop pipeline. The air source heat pump unit 1 releases the stored air energy to heat the water in the closed loop pipeline and maintain the water temperature of the shrimp farming area 5 unchanged.
[0049] When the water in shrimp farming area 5 needs to be replaced, the shrimp farming area 5 must first be drained. At this time, the sewage submersible pump 10 is turned on to connect the sewage tank 2 with the water in shrimp farming area 5, and the water in shrimp farming area 5 is discharged into the sewage tank 2. After the water is drained, the sewage submersible pump 10 is turned off. Then, the shrimp farming area 5 is replenished with water. At this time, the water storage tank 6 submersible pump is turned on to connect the water storage tank 6 with the water in shrimp farming area 5, and the water in the water storage tank 6 is added into shrimp farming area 5 to replace the water.
[0050] When the water in shrimp farming area 5 has just been replaced, and the wastewater source heat pump unit 4 is started, such as... Figure 3 As shown, turn on the sewage source water pump 7, connect the sewage tank 2, the anti-blocking machine 3 and the sewage source heat pump unit 4. The sewage source heat pump unit 4 collects the waste heat in the sewage and discharges the sewage after the waste heat is collected through the outlet on side A. After the collection is completed, turn off the sewage source water pump 7. Then open the two valves between the outlet and inlet on side B of the sewage source heat pump unit 4 and the three-way fittings at both ends of the water heating pipeline, and turn on the end-side circulating water pump 11 to form a closed loop pipeline between the sewage source heat pump unit 4 and the water heating pipeline. At this time, the sewage source heat pump unit 4 releases the collected waste heat to heat the water in the closed loop pipeline and maintain the water temperature of the shrimp farming area 5 unchanged.
[0051] After the water in the reservoir 6 is added to the shrimp farming area 5, the reservoir 6 needs to be replenished.
[0052] When replenishing water to reservoir 6, such as Figure 4 As shown, turn on the submersible water pump 8, open the valve between the inlet of the water storage tank 6 and the outlet of the air source heat pump unit 1, and keep both valves between the three-way components at both ends of the inlet and outlet of the air source heat pump unit 1 and the three-way components at both ends of the water heating pipe closed, so that the tap water flows into the air source heat pump unit 1 from the tap water inlet 17, the air source heat pump unit 1 releases energy to heat the tap water, and the heated tap water enters the water storage tank 6.
[0053] Advantages of this utility model:
[0054] This invention utilizes a combined air source and wastewater source system. When the water in the shrimp farming area is not changed, the air source heat pump unit is activated, connecting it to the water heating pipeline in the shrimp farming area to fully absorb air energy and maintain a constant water temperature. When the water in the shrimp farming area is changed, a storage tank is connected to the water in the shrimp farming area to replace the water. Shortly after the water has been replaced, the wastewater source heat pump system is activated, connecting it to the water heating system in the shrimp farming area to fully absorb wastewater heat and maintain a constant water temperature.
