Description

Technical Field

[0001] The present invention relates to the technical field of renewable energy utilization, and particularly relates to a storage system and method. Background Art

[0002] The utilization of reclaimed water and heat pump technology play important roles in the fields of energy and water resource management. With the global promotion of the goals of "carbon peak" and "carbon neutrality", the combined application of reclaimed water and heat pump systems has become a major trend. In modern urban water resource management and heating systems, the storage systems of reclaimed water treatment plants and water source heat pump stations play a crucial role. These systems can not only improve the reuse rate of water resources, but also utilize the heat energy in reclaimed water to achieve the effect of energy conservation and emission reduction.

[0003] However, the existing reclaimed water treatment plants and water source heat pump stations face many problems during operation. First of all, when the reclaimed water treatment plant supplies water to the municipal reclaimed water pipeline, it is necessary to build storage structures such as clear water tanks; similarly, the water intake of the municipal water source heat pump station also requires a separate storage structure. These storage structures are often idle during the non-heating season, resulting in waste of resources. Secondly, the construction investment of traditional storage systems is high and the floor area is large, which not only increases the economic cost of the project, but also occupies a large amount of land resources. In addition, when reclaimed water is used as the water source, the heat pump only extracts the heat in the water, and the reclaimed water still needs to be reused, which poses higher requirements for the design of the storage system.

[0031] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0032] Now, various embodiments of the present invention will be described in detail. Examples of these embodiments are shown in the drawings and described as follows. For the purpose of explanation and precise definition in the appended claims, the terms "upper", "lower", "inner" and "outer" are used to describe these features with reference to the positions of the features of the exemplary embodiments shown in the drawings.

[0033] Embodiments of the present invention provide a storage system and method, which can solve the problems of deficiencies in aspects such as comprehensive utilization of space, land saving, and project investment in the related art.

[0034] According to one aspect of the present invention, a storage system is provided, as Figure 1 shown, including: a first clean water tank for storing high - temperature water from a water distribution channel; a water source heat pump station for extracting heat from the high - temperature water to obtain low - temperature water; a second clean water tank connected to the water source heat pump station for storing the low - temperature water; and a regeneration pump station connected to the first clean water tank and the second clean water tank respectively for realizing the reuse of the high - temperature water and the low - temperature water.

[0035] In the related art, it is often necessary to construct independent clean water tanks for the reclaimed water treatment plant and the water source heat pump station respectively, which not only increases the investment cost but also occupies a large amount of land resources. In addition, during the non-heating season, the regulating structures are often idle, resulting in waste of resources. When the traditional system processes water resources at different temperatures, it lacks effective integration and management, leading to low system operation efficiency. In the embodiments of the present invention, by providing an integrated regulating system, the regulating functions of the reclaimed water and the water source heat pump system are combined together. By using the first clean water tank and the second clean water tank, the investment and land occupation can be significantly reduced. By storing high-temperature water and low-temperature water in the first clean water tank and the second clean water tank respectively, efficient heat extraction and repeated utilization of water resources are realized, and the overall resource utilization rate of the system is significantly improved. During the non-heating season, the system can flexibly switch to the working mode of the reclaimed water pump station working alone, make full use of the existing regulating facilities, avoid waste of resources, and improve the operation efficiency of the system.

[0036] According to the embodiments of the present invention, the regulating system further includes: a stop log gate, located in the water distribution channel, between the first electric gate communicating with the first clean water tank and the second electric gate communicating with the second clean water tank, and the height of the stop log gate is adjusted according to the water temperature in the water distribution channel.

[0037] In the related art, the water flow control of the regulating system usually depends on a gate with a fixed height, which cannot be flexibly adjusted according to the real-time changing water temperature, resulting in low regulating efficiency of high-temperature water and low-temperature water. When processing water resources at different temperatures, the utilization of water resources cannot be effectively optimized, leading to low system operation efficiency and low heat energy utilization rate. In addition, when the water temperature changes greatly, it is difficult for the gate with a fixed height to ensure the stability and operation efficiency of the regulating system. In the embodiments of the present invention, by setting a stop log gate in the water distribution channel, the height of the stop log gate can be flexibly adjusted according to the water temperature in the water distribution channel, solving the problem of low regulating efficiency caused by the fixed height of the gate in the traditional system. Specifically, when the water temperature in the water distribution channel is high, the height of the stop log gate increases, allowing more high-temperature water to preferentially enter the first clean water tank and extract heat through the water source heat pump station; when the water temperature is low, the height of the stop log gate decreases, and more water enters the second clean water tank, reducing heat loss. This design improves the heat extraction efficiency of the water source heat pump and the water resource utilization rate, and at the same time enhances the adaptability and operation stability of the system under different water temperature conditions.

[0038] According to the embodiments of the present invention, when the water temperature T is lower than or equal to the lowest temperature threshold T min , the stop log gate is fully opened, the water source heat pump station is closed, and the third electric gate between the reclaimed water pump station and the first clean water tank and the fourth electric gate between the reclaimed water pump station and the second clean water tank are both opened.

[0039] In the embodiment of the present invention, by setting that when the water temperature is lower than or equal to the lowest temperature threshold, the stoplog gate is fully opened, so that the water flow directly enters the clear water tank without passing through the heat pump system, thus avoiding the energy waste caused by the operation of the heat pump system under unsuitable conditions. At the same time, the water source heat pump station is closed, and the electric gates between the regeneration water pump station and the first clear water tank and the second clear water tank are opened, so that the regeneration water can circulate and be utilized efficiently between the clear water tanks. Through this automatic control strategy, the system can dynamically adjust the operation state according to the real-time water temperature conditions and optimize the energy utilization.

[0040] According to the embodiment of the present invention, when the water temperature T is higher than the lowest temperature threshold T min , the relationship between the height H of the stoplog gate and the water temperature T satisfies:

[0041]

[0042] wherein, T op is a preset temperature, H max is the height of the water distribution channel, e is a mathematical constant; the third electric gate between the regeneration water pump station and the first clear water tank is closed, and the fourth electric gate between the regeneration water pump station and the second clear water tank is opened.

[0043] In the embodiment of the present invention, by providing a formula for dynamically adjusting the height of the stoplog gate according to the water temperature, it is realized that the higher the water temperature, the higher the height of the stoplog gate, so that more high-temperature water preferentially enters the first clear water tank, thereby extracting heat more efficiently. The present invention thus improves the operation efficiency and resource utilization rate of the system under different temperature conditions.

[0044] According to the embodiment of the present invention, the relationship between the power P of the water source heat pump station, the water supply rate Q, the temperature T and the water level H1 of the first clear water tank satisfies:

[0045]

[0046] wherein, P min is the minimum operating power of the water source heat pump station, P max is the maximum operating power of the water source heat pump station, T op is a preset temperature, H max is the height of the water distribution channel, H1 is the water level of the first clear water tank, Q is the water supply rate of the water source heat pump station, η is the loss ratio, C is the specific heat capacity of water, T out is the water temperature of the low-temperature water.

[0047] In the embodiment of the present invention, by providing a formula for dynamically adjusting the power and water supply rate of the water source heat pump station according to the water temperature and the water level of the first clear water tank, it is ensured that the system can be flexibly adjusted under different working conditions. Through the linkage control with the real-time water temperature and water level, the system can manage heat energy and water resources more efficiently.

[0048] According to an embodiment of the present invention, a connected fifth electric gate is provided between the first clear water tank and the second clear water tank. Wherein, when the water level H1 in the first clear water tank rises and is higher than the set high threshold H high when, the fifth electric gate opens; when the water level H1 in the first clear water tank drops and is lower than the set low threshold H low when, the fifth electric gate closes.

[0049] In an embodiment of the present invention, when the water level in the first clear water tank rises above the set high threshold, the fifth electric gate opens, and the excess water flows into the second clear water tank, avoiding overflow and waste of water resources; when the water level drops below the set low threshold, the fifth electric gate closes, ensuring the effective regulation of water resources in the first clear water tank. This design not only improves the operating stability of the system under water level fluctuations, but also optimizes the water resource allocation and utilization between the clear water tanks, enhancing the overall operating efficiency and reliability of the system.

[0050] According to an embodiment of the present invention, an overflow weir is provided at the end of the water distribution channel for discharging water exceeding the accommodation capacity of the regulation system; when the water level H2 in the second clear water tank rises and is higher than the set high threshold H high when, the overflow weir opens, and the drainage rate Q out of the overflow weir and the water level H2 in the second clear water tank satisfy:

[0051]

[0052] wherein, Q max is the maximum drainage rate of the overflow weir, H max is the height of the water distribution channel; when the water level H2 in the second clear water tank drops and is lower than the set low threshold H low when, the overflow weir closes.

[0053] In an embodiment of the present invention, by providing an overflow weir at the end of the water distribution channel, it is possible to prevent the water level in the clear water tank from continuing to rise, ensure the safe operation of the system, and significantly improve the operating efficiency and stability of the system.

[0054] According to another embodiment of the present invention, a regulation method is provided, as Figure 5 shown, including: regulating the high-temperature water from the water distribution channel; extracting the heat from the high-temperature water to obtain low-temperature water; regulating the low-temperature water; and realizing the reuse of the high-temperature water and the low-temperature water.

[0055] In the related art, existing energy storage methods usually handle high-temperature water and low-temperature water separately, lacking a unified energy storage and management mechanism, resulting in low heat extraction efficiency and serious resource waste. In addition, during the energy storage process of high-temperature water and low-temperature water, existing methods lack effective heat management and reuse measures, further reducing the operating efficiency and resource utilization rate of the system. In the embodiments of the present invention, by providing an integrated energy storage method, efficient management of high-temperature water and low-temperature water is achieved. Specifically, the present invention stores high-temperature water from the water distribution channel and extracts heat from the high-temperature water using a water source heat pump station to obtain low-temperature water. Then, by storing the low-temperature water in the second clear water tank, the efficient progress of the heat extraction process is ensured. In addition, the present invention can realize the reuse of high-temperature water and low-temperature water, using the high-temperature water for heating or other applications that require heat energy, while the low-temperature water is used to supplement the reclaimed water system or other low-temperature water demand scenarios. By this method, not only the heat extraction and water resource utilization efficiency are improved, but also flexible energy storage and reuse can be achieved under different temperature conditions, optimizing the overall operating efficiency and resource management effect.

[0056] According to an embodiment of the present invention, before storing the high-temperature water from the water distribution channel, the method further includes: adjusting the height of the stop log gate according to the water temperature of the water distribution channel, where the stop log gate is located in the water distribution channel, between the first electric gate connecting the first clear water tank and the second electric gate connecting the second clear water tank.

[0057] In the embodiments of the present invention, by adjusting the height of the stop log gate according to the water temperature of the water distribution channel before storing the high-temperature water, the system can adjust the water flow path and flow rate according to the real-time water temperature, optimizing the energy storage and utilization efficiency of high-temperature water and low-temperature water.

[0058] According to an embodiment of the present invention, adjusting the height of the stop log gate according to the water temperature of the water distribution channel includes: when the water temperature T of the water distribution channel is lower than or equal to the lowest temperature threshold T min 0, fully opening the stop log gate, closing the water source heat pump station, and simultaneously opening the third electric gate between the reclaimed water pump station and the first clear water tank and the fourth electric gate between the reclaimed water pump station and the second clear water tank; when the water temperature T of the water distribution channel is higher than the lowest temperature threshold T min 0, closing the third electric gate, opening the fourth electric gate, and adjusting the height of the stop log gate according to the following relationship:

[0059]

[0060] where, T op 0 is a preset temperature, H max is the height of the water distribution channel, and e is a mathematical constant.

[0061] In the related art, in the face of different water temperature conditions, there is often a lack of an effective automatic adjustment mechanism, resulting in low system operation efficiency. When the water temperature is low, the heat pump system still operates, wasting energy; while when the water temperature is high, heat extraction and water resource management cannot be optimized. In addition, the gates with fixed heights in the existing systems cannot be adjusted according to the real-time water temperature, further limiting the flexibility and adaptability of the systems. In the embodiments of the present invention, by adjusting the height of the stoplog gate according to the water temperature of the water distribution channel, the system can optimize the water flow path and heat management according to the real-time water temperature, improve the heat energy extraction and water resource utilization efficiency, and enhance the adaptability and stability of the system under different temperature conditions.

[0062] Take the combined construction of the reclaimed water pump house and the water source heat pump station in a certain reclaimed water treatment plant as an example below.

[0063] The water distribution channel and the clear water tank are arranged in the middle of the system, and the water source heat pump station and the reclaimed water pump house are arranged on both sides.

When clear water tank 1 is full, the inlet water can overflow into clear water tank 2; an overflow weir is arranged at the end of the water distribution channel, and the outlet pipe behind the weir can discharge water into the river by gravity. A flow meter 2, denoted as q2, is set on the drain pipe.

[0064] The clear water tank is divided into No. 1 and No. 2. Liquid level gauges 1 and 2 are respectively arranged in the tanks, and the outlet water is respectively connected to the No. 1 and No. 2 suction wells through electric gates 3 and 4; an electric gate 6 is additionally arranged on the No. 1 clear water tank and is connected to the No. 3 suction well; an electric gate 5 is arranged between the No. 1 and No. 2 suction wells for connection.

[0065] The reclaimed water pump house is equipped with a total of three pump systems for factory reclaimed water, municipal reclaimed water and other reclaimed water, and valves and flow meters 5, 6 and 7 are respectively arranged, denoted as t5, t6 and t7; the water intake is connected from the No. 1 and No. 2 suction wells.

[0066] The water source heat pump station is equipped with a heat pump unit, a heat pump water supply pump group and a return water pipeline. Supporting valves, flow meters 3 and 4 and thermometers 1 and 2 are respectively arranged on the heat pump water supply pump group and the return water pipeline, denoted as q3, q4, t1 and t2; the heat pump water supply pump group takes water from the No. 3 suction well and returns the water to the No. 2 clear water tank.

[0067] Condition 1

[0068] As Figure 2 shown, during the heating (cooling) season, the water source heat pump station and the reclaimed water pump house work simultaneously.

The heat extracted by the water source heat pump station is Q = cm·(t1 - t2). The water source heat pump station only extracts the heat of the reclaimed water and does not consume water. All the reclaimed water can still be used by the original users or supplemented to the river channel.

[0070] Operating condition 2

[0071] As Figure 3 shown, during the non-heating (cooling) season, only the reclaimed water pump house operates.

[0072] The electric gates 1, 2, 3, and 4 are opened, and the electric gate 6 is closed; the flap gate is fully opened; at this time, the flow rates of each pipeline are as follows: q1 = q2 + q5 + q6 + q7, q3 = q4 = 0; all the reclaimed water can be jointly regulated by the 1# and 2# clean water tanks. The reclaimed water is used by users or supplemented to the river channel, and the water source heat pump station is shut down or under maintenance.

[0073] Operating condition 3

[0074] As Figure 4 shown, during the maintenance of the 1# clean water tank and the 1# suction tank, only the reclaimed water pump house operates.

[0075] The electric gates 2 and 4 are opened, and the electric gates 1 and 5 are closed; the flap gate is fully opened; at this time, the flow rates of each pipeline are as follows: q1 = q2 + q5 + q6 + q7, q3 = q4 = 0. All the reclaimed water is regulated by the 2# clean water tank. The reclaimed water is used by users or supplemented to the river channel; through the switching of the gates, various operating conditions such as the separate maintenance of the 2# clean water tank and the 2# suction tank can also be realized, which will not be elaborated here.

[0076] In summary, the present invention has the following advantages:

[0077] (1) By adjusting the height of the flap gate and flexibly controlling the water flow path according to the water temperature, the efficient management and utilization of high-temperature water and low-temperature water are realized, and the overall operation efficiency and resource utilization rate of the system are improved.

[0078] (2) When the water temperature is relatively low, the water source heat pump station is automatically shut down and the electric valve between the reclaimed water pump station and the clean water tank is opened, avoiding energy waste and ensuring the effective regulation and reuse of water resources under low-temperature conditions.
