Description

A regulating pool Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and in particular to an equalization tank. Background Technology

[0002] In the field of wastewater treatment, due to the uneven influent flow at wastewater treatment plants, a regulating tank is typically installed after the collection tank to balance and regulate the influent flow and quality, thereby reducing the load impact on subsequent treatment units. Currently, traditional regulating tanks are variable-level tanks. To ensure the uniformity and stability of water quality and quantity in subsequent treatment units, a secondary booster pump is generally used to lift the effluent, achieving a constant flow rate. Therefore, before entering the treatment units, the wastewater from the treatment plant generally needs to undergo two lifts: from the collection tank into the regulating tank, and then from the regulating tank effluent into the treatment units. Consequently, the regulating tank booster pump needs to operate continuously, resulting in significant energy consumption.

[0003] Existing invention patent CN114506888A discloses a non-powered sewage equalization tank, which consists of an outer tank outside the equalization tank and a waterproof membrane inside the equalization tank. The outer tank and the equalization tank are connected by a connecting pipe. Based on the principle of the connector, the water level in the equalization tank is kept basically stable, achieving gravity flow of water at a stable pressure. The equalization tank effluent does not require a booster pump, which reduces energy consumption in the sewage treatment process. However, it also requires a large-volume outer tank, thus increasing construction costs. Therefore, there is an urgent need to propose an equalization tank that can balance energy consumption and cost. Summary of the Invention

[0004] The main objective of this invention is to propose a regulating pool that addresses the problem of balancing energy consumption and cost in existing regulating pool technologies.

[0005] To achieve the above objectives, the present invention provides an equalization tank, which includes an equalization tank body, wherein the equalization tank body is a sealed tank body;

[0006] The upper end of the regulating tank body is connected to the energy storage unit via an air pipe, and the energy storage unit includes an airbag.

[0007] The lower end of the regulating tank body is provided with a first connecting pipe and a second connecting pipe. The first connecting pipe is connected to the front well, which is used to connect to the water collection tank through a hydraulic lifting device. The second connecting pipe is used to connect to the treatment tank.

[0008] Optionally, an air replenishment unit is also connected between the regulating tank body and the energy storage unit, and the air replenishment unit includes an air pump and a pressure regulating valve.

[0009] Optionally, a control valve is provided on the first connecting pipe.

[0010] Optionally, a first electric valve is provided on the air pipe.

[0011] Optionally, a flow control unit is provided on the second connecting pipe, the flow control unit including a flow meter and a second electric valve.

[0012] Optionally, the regulating tank body is provided with a stirring structure.

[0013] Optionally, the energy storage unit may also include a pressure gauge.

[0014] Optionally, the airbag is an elastic structure.

[0015] Optionally, the treatment tank is connected to an outlet pipe, and the upper end of the collection tank is connected to an inlet pipe.

[0016] Beneficial effects:

[0017] This invention proposes a regulating tank, comprising a tank body, which is a sealed tank body. The upper end of the regulating tank body is connected to an energy storage unit via an air pipe, the energy storage unit including an air bladder. The lower end of the regulating tank body is respectively provided with a first connecting pipe and a second connecting pipe. The first connecting pipe is connected to a front well, which is used to connect to a collection tank via a hydraulic lifting device. The second connecting pipe is used to connect to a treatment tank. Furthermore, air flows within the regulating tank body under sealed conditions via the air bladder, using gas as a pressure regulating medium to achieve gravity-flow water discharge from the regulating tank. This eliminates the need for pump lifting, saving energy and reducing construction costs. The tank also boasts high utilization, a large adjustable liquid level range, and requires no maintenance points. In addition, the pressure variation within this regulating tank is only 10%–20% of that of traditional regulating tanks, with the pressure fluctuating within a small range, resulting in better structural safety and facilitating widespread application.

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature.

[0027] Referring to Figure 1, the present invention provides a regulating pool, wherein the regulating pool includes a regulating pool body 5, the regulating pool body 5 is a sealed pool body, and generally, a manhole 51 is also provided on the top of the regulating pool body 5, the purpose of which is to facilitate maintenance and inspection of the interior of the regulating pool body 5.

[0028] Meanwhile, the upper end of the regulating tank body 5 is connected to the energy storage unit 6 via an air pipe 53. The energy storage unit 6 includes an air bladder 61, which is an elastic structure and preferably made of rubber. The lower end of the regulating tank body 5 is respectively provided with a first connecting pipe 55 and a second connecting pipe 56. The first connecting pipe 55 is connected to the front well 4, which is used to connect to the collection tank 2 via a hydraulic lifting device. The second connecting pipe 56 is used to connect to the treatment tank 9. Generally, the hydraulic lifting device includes a lifting pump 3 or an air lifting device. This structural arrangement enables the regulating tank to continuously supply water to the subsequent treatment tank via gravity flow. The principle of its gravity-flow water discharge is as follows: When the sewage output flow rate of the collection tank 2 is greater than the outflow flow rate of the regulating tank body 5, the liquid level in the regulating tank body 5 rises, and the air pressure above the liquid surface in the regulating tank body 5 increases, with some air being compressed into the air bladder 61. Conversely, when the output flow rate of the collection tank 2 is less than the outflow flow rate of the regulating tank body 5, the liquid level in the regulating tank body 5 drops, and the air pressure inside the regulating tank body 5 decreases. Some air then enters the regulating tank body 5 from the air bladder 61 to replenish the space after the water discharge from the regulating tank body 5. Thus, by using gas as a pressure regulating medium, the regulating tank achieves continuous gravity flow, eliminating the need for pump lifting and saving energy. Furthermore, the entire volume of the regulating tank body is usable, thereby improving the volume utilization rate of the regulating tank body. The overall structure is simple and convenient, and easy to maintain. In addition, there are no joints between rigid and flexible materials inside the regulating tank, eliminating the need for sealing. The air bladder deforms synchronously in all directions, with no stress concentration points, resulting in a long service life.

[0029] Furthermore, an air replenishment unit 7 is connected between the regulating tank body 5 and the energy storage unit 6. The air replenishment unit 7 includes an air pump 71 and a pressure regulating valve 72. When the sum of the pressures above the liquid surface in the regulating tank body 5 and the pressure inside the air bladder 61 is less than a preset range, air can be replenished to the energy storage unit 6 through the air replenishment unit 7, i.e., through the air pump 71 and the pressure regulating valve 72. This ensures that the pressures above the liquid surface in the regulating tank body 5 and the pressure inside the air bladder 61 are within the preset range. Generally, the pressure reduction within this range is due to some air dissolving in the water.

[0030] Furthermore, a control valve 41 is provided on the first connecting pipe 55 to realize the opening and closing of the connection between the control well 4 and the regulating tank body 5.

[0031] Furthermore, a first electric valve 54 is provided on the air pipe 53 to facilitate the adjustment of the connection between the airbag 61 and the regulating pool body 5. Specifically, when the regulating pool body 5 is at its maximum water depth, the pressure inside the airbag 61 is the pressure value corresponding to 0.1 to 0.15 times the maximum water depth inside the regulating pool body 5.

[0032] Furthermore, the energy storage unit 6 also includes a pressure gauge 62, which is used to monitor the pressure value inside the airbag 61 in real time. If the pressure value measured in the pressure gauge 62 exceeds the preset range, an early warning or reminder program will be activated to attract the attention of relevant personnel and handle the situation in a timely manner.

[0033] Furthermore, a flow control unit 8 is provided on the second connecting pipe 56, the flow control unit 8 including a flow meter 82 and a second electric valve 81. The flow meter 82 is used to detect the outflow of water in the second connecting pipe 56 in real time, and the second electric valve 81 is used to control the opening and closing of the connection between the regulating tank body 5 and the treatment tank 9, and to maintain the outflow of water from the regulating tank body 5 within a preset range. When the flow rate measured by the flow meter 82 does not reach the preset range and cannot be restored, the air replenishment unit 7 is activated to replenish air to the energy storage unit 6, and stops when the value in the pressure gauge 62 reaches the preset range.

[0034] Preferably, the pressure value of the outlet of the second connecting pipe 56 is 1.1-1.15 times the maximum water depth, wherein the maximum water depth refers to the water depth when the regulating tank body 5 is full.

[0035] Furthermore, the regulating tank body 5 is provided with a stirring structure 52, preferably a submersible mixer.

[0036] Furthermore, the treatment tank 9 is connected to an outlet pipe 10, and the upper end of the water collection tank 2 is connected to an inlet pipe 1.
