[0019] The specific implementation of the embodiment of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the embodiment of the present invention, and is not used to limit the embodiment of the present invention.

[0020] In the embodiments of the present invention, unless otherwise specified, directional words such as "up, down, left, right" generally refer to the directions or positional relationships shown in the accompanying drawings, or the directions or positional relationships in which the inventive product is usually placed when in use.

[0021] The terms “first”, “second”, “third”, etc. are only used for distinguishing descriptions and should not be understood as indicating or implying relative importance.

[0022] The terms "parallel", "vertical", etc. do not mean that the components must be absolutely parallel or vertical, but can be slightly tilted. For example, "parallel" only means that its direction is more parallel than "vertical", and does not mean that the structure must be completely parallel, but can be slightly tilted.

[0023] The terms "horizontal", "vertical", "overhanging" and the like do not mean that the components are required to be absolutely horizontal, vertical or overhanging, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0024] In addition, the terms "roughly" and "basically" are intended to explain that the relevant content does not require absolute precision, but can have certain deviations. For example, "roughly equal" does not only mean absolute equality. Since it is difficult to achieve absolute "equality" in actual production and operation, there are generally certain deviations. Therefore, in addition to absolute equality, "roughly equal" also includes the above-mentioned situation with certain deviations. Taking this as an example, in other cases, unless otherwise specified, the terms "roughly" and "basically" have similar meanings to the above.

[0026] Figure 1 It is a schematic diagram of the structure of the water treatment aeration pipe provided by the present invention; Figure 2 is a cross-sectional schematic diagram of the aeration sub-pipe provided by the present invention; Figure 3It is a flow chart of a first flow control method of a water treatment aeration pipe provided by the present invention; Figure 4 It is a flow chart of a second flow control method for a water treatment aeration pipe provided by the present invention.

[0027] like Figure 1-2 As shown, this embodiment provides a water treatment aeration pipe, the pipe comprising: A gas main pipe 1, wherein the gas inlet end of the gas main pipe 1 is connected to the gas outlet end of the gas pressurizing device 2; A plurality of aeration sub-pipes 3 independently arranged from each other are arranged at intervals in the wastewater tank through a fixing mechanism 4, aeration holes 31 are arranged at intervals on each aeration sub-pipe 3, each aeration sub-pipe 3 is connected to the gas outlet end of the gas main 1 through a transition pipe 5, and each transition pipe 5 is provided with a flow regulating mechanism 6, and the flow regulating mechanism 6 is used to regulate the gas flow and pressure entering the corresponding aeration sub-pipe 3; A plurality of pressure detection devices 7, used to detect the gas pressure value in the aeration sub-pipeline 3, each aeration sub-pipeline 3 is provided with a pressure detection device 7; The controller 8 is connected to the gas pressurizing device 2, all the pressure detecting devices 7 and all the flow regulating mechanisms 6, and is used to control the opening of the corresponding flow regulating mechanism 6 based on the gas pressure value of the corresponding aeration sub-pipeline 3 to adjust the gas flow and pressure of the corresponding aeration sub-pipeline 3, and adjust the operating power of the gas pressurizing device 2.

[0028] Specifically, in this embodiment, the diameter of the gas main 1 is larger than the diameter of the transition pipe 5 and the aeration sub-pipe 3 to ensure that the gas entering the transition pipe 5 and the aeration sub-pipe 3 has a certain pressure. At the same time, the flow rate in the aeration sub-pipe 3 can be adjusted by the flow regulating mechanism 6, thereby adjusting the gas pressure in the pipe. The pressure detection device 7 can be arranged at the air inlet end of the aeration sub-pipe 3 to ensure the accuracy of pressure data collection, and avoid the problem of inaccurate pressure data collection when the aeration sub-pipe 3 is blocked in the middle section due to the rearward setting position. The number of aeration sub-pipes 3 can be set according to the size of the wastewater tank to ensure that the gas can be uniformly injected into the wastewater tank; the material of the aeration sub-pipe 3 is UPVC, PE, ABS, 304, 316, duplex steel, etc., the opening at the bottom of the aeration sub-pipe 3 (the lower end face of the aeration sub-pipe 3) is Φ5~Φ10mm, the spacing is 200~500, and it is staggered at a 45-degree angle, and the opening is a tapered hole, and the large end of the tapered hole faces the outside of the pipe. The controller 8 is connected to the gas pressurizing device 2, all the pressure detection devices 7 and all the flow regulating mechanisms 6, and can automatically control the corresponding flow regulating mechanism 6 to adjust the gas flow of the corresponding aeration sub-pipe 3 and the operating power of the gas pressurizing device 2 based on the gas pressure value of the corresponding aeration sub-pipe 3 to ensure that the gas pressure meets the usage requirements.

[0029] In the above scheme, each aeration sub-pipe is connected to the gas outlet end of the gas main through a transition pipe to realize independent gas supply, and a flow regulating mechanism is provided on each transition pipe to realize the regulation of the gas flow entering the aeration sub-pipe. The overall structure is simple, the energy consumption is low, and the pipeline flow can be accurately adjusted. In the early stage of blockage, the gas pressure in the pipeline is increased for blowing and exhaust, thereby effectively preventing blockage of the aeration sub-pipe.

[0030] Furthermore, a buffer cavity 11 is provided at the gas outlet end of the gas main pipe 1 , and the gas inlet end of each transition pipe 5 is connected to the buffer cavity 11 .

[0031] Specifically, in this embodiment, a buffer cavity 11 is provided at the outlet end of the gas main 1, and the inlet end of each transition duct 5 is connected to the buffer cavity 11. After compression, the compressed gas enters the gas main 1. If the inlet end of the transition duct 5 is directly connected to the gas main 1, the gas pressure entering the transition duct 5 will be different. Therefore, after the buffer cavity 11 is provided for gas buffering, the stability of the input pressure can be ensured in the input transition duct 5. More specifically, the buffer cavity 11 can be set as a hemispherical structure, the outlet end of the gas main 1 is connected to the convex surface of the hemispherical surface, and the inlet end of the transition duct 5 is evenly connected to the plane of the hemispherical surface.

[0032] Furthermore, a plurality of pipe supports are provided in the wastewater tank; The fixing mechanism 4 includes a plurality of pipe clamps connected to corresponding pipe supports via bolts.

[0033] Specifically, in this embodiment, the aeration sub-pipe 3 is installed and fixed on the pipe support by a pipe clamp, so that the aeration sub-pipe 3 is fixed to the wastewater tank. This method is convenient for installation, fixing and disassembly.

[0034] More specifically, the pipe support is welded to the embedded parts at the bottom of the pool. According to the water quality, the pipe support is uniformly anti-corrosive after welding. The bottom plate anti-corrosion layer covers the bottom of the pool and the embedded parts. The pipe clamp and nut can be made of UPVC, 304, 316, 316L, 317, or duplex steel corrosion-resistant materials according to different water qualities. The length is twice the thickness of the support + the circumference of the round pipe + twice the thickness of the nut. The distance between the two holes of the pipe clamp is the pipe diameter. The pipe support can be a channel steel or a round pipe with a steel plate on top. It can be rotated according to economic efficiency. The holes on it match the pipe clamp. It can be uniformly anti-corrosive before the pipe is installed. The anti-corrosion form is glass fiber reinforced plastic, polyurea anti-corrosion, or UPVC, 304, 316. The material of the embedded parts at the bottom of the pool can be carbon steel, 304, 316, or 316L according to different water qualities. The length or width is greater than 50mm on each side of the pipe support.

[0035] Further, the gas pressurizing device 2 is a gas compressor; The flow regulating mechanism 6 is an electric valve or a pneumatic valve.

[0036] Specifically, the gas pressurizing device 2 is a gas compressor, which can compress the gas, so that the gas introduced into the pipeline has a certain pressure, thereby ensuring the injection effect; in addition, the flow regulating mechanism 6 is an electric valve or a pneumatic valve, which can realize remote on-off control, thereby improving the convenience and flexibility of use.

[0037] The embodiment of the present invention also provides a flow control method for a water treatment aeration pipe, such as Figure 3 As shown, the method includes: Step 1: confirm that the gas supply start instruction has been received, and adjust each flow regulating mechanism to a first preset opening; Step 2: Obtain the actual gas pressure value of each aeration sub-pipeline in real time; Step 3: If the difference between the actual gas pressure value of any aeration sub-pipeline and the first preset pressure value is greater than the set difference threshold and lasts for the first preset time, the flow regulating mechanism corresponding to the aeration sub-pipeline is adjusted to the second preset opening; Step 4: from the moment when the flow regulating mechanism corresponding to the aeration sub-pipeline is adjusted to the second preset opening, after the second preset time has passed, the flow regulating mechanism corresponding to the aeration sub-pipeline is adjusted to the first preset opening; The first preset opening is smaller than the second preset opening.

[0038] Specifically, after the process of introducing gas into the wastewater pool, first, an external signal is input through a keyboard, touch screen, etc. to generate a start gas supply instruction, and the start gas supply instruction is sent to the controller. After receiving the start gas supply instruction, the controller controls the gas pressurizing device to compress the gas according to a preset reference power, and adjusts each flow regulating mechanism to a first preset opening. When operating under the reference power, the gas pressure value in each aeration sub-pipeline is theoretically the same, and even if there is a certain deviation, the deviation value is small; at this time, the actual gas pressure value of each aeration sub-pipeline is obtained in real time; if the difference between the actual gas pressure value of any aeration sub-pipeline and the first preset pressure value is greater than the set difference threshold (when the aeration hole is blocked, the pressure in the aeration sub-pipeline will increase slightly), therefore, the difference between the actual gas pressure value of the aeration sub-pipeline and the first preset pressure value is greater than the set difference threshold (when the aeration hole is blocked, the pressure in the aeration sub-pipeline will increase slightly), therefore, the difference between the actual gas pressure value of the aeration sub-pipeline and the first preset pressure value is greater than the set If the difference threshold value continues for the first preset time, it means that the pressure value change is not accidental but exists for a long time, which means that the aeration hole is indeed blocked at this time and is in the initial stage of blockage. Therefore, the flow regulating mechanism corresponding to the aeration sub-pipeline is adjusted to the second preset opening. After adjusting to the second preset opening, the gas flow entering the aeration sub-pipeline increases, and when the gas discharge volume remains unchanged, the corresponding gas pressure will increase, thereby flushing the blocked aeration control and effectively avoiding the aggravation of the blockage. However, since the flow regulating mechanism is adjusted to the first preset opening, it is the optimal amount of gas injected. Continuing to increase the gas injection amount cannot effectively improve the water treatment effect. Therefore, in order to reduce energy waste, from the moment when the flow regulating mechanism corresponding to the aeration sub-pipeline is adjusted to the second preset opening, after the second preset time, the flow regulating mechanism corresponding to the aeration sub-pipeline is adjusted to the first preset opening.

[0039] In the above scheme, each aeration sub-pipe is connected to the gas outlet end of the gas main through a transition pipe to realize independent gas supply, and a flow regulating mechanism is provided on each transition pipe to realize the regulation of the gas flow entering the aeration sub-pipe. The overall structure is simple, the energy consumption is low, and the pipeline flow can be accurately adjusted. In the early stage of blockage, the gas pressure in the pipeline is increased for blowing and exhaust, thereby effectively preventing blockage of the aeration sub-pipe.

[0040] Furthermore, if Figure 4 As shown, the method also includes: After a third preset time has passed since the moment when the flow regulating mechanism corresponding to the aeration sub-pipeline is adjusted to the first preset opening for the second time, the actual pressure value of the gas in the aeration sub-pipeline is obtained again; If the difference between the re-acquired actual gas pressure value of the aeration sub-pipeline and the first preset pressure value is still greater than the set difference threshold, an alarm is generated.

[0041] Specifically, after high-pressure gas injection is performed on the clogged aeration sub-pipe, in order to verify whether there is still a blockage in the aeration sub-pipe, after a second preset time, the flow regulating mechanism corresponding to the aeration sub-pipe is adjusted to a first preset opening, and after a third preset time (to avoid misjudgment of the result due to chance), the actual gas pressure value of the aeration sub-pipe is obtained again. If the difference between the re-obtained actual gas pressure value of the aeration sub-pipe and the first preset pressure value is still greater than the set difference threshold, it means that the aeration sub-pipe is still clogged, and the blockage cannot be effectively reduced by injecting gas. In order to avoid further deterioration, an alarm is generated to notify maintenance personnel to perform manual maintenance.

[0042] Furthermore, the method further comprises: If there are two or more aeration sub-pipes at the same time where the difference between the actual gas pressure value and the first preset pressure value is greater than the set difference threshold and lasts for a certain period of time, then based on the number of aeration sub-pipes where the difference between the actual gas pressure value and the first preset pressure value is greater than the set difference threshold and lasts for a certain period of time, the operating power of the gas pressurizing device is adjusted, and the flow regulating mechanisms corresponding to the two or more aeration sub-pipes are adjusted to the second preset opening.

[0043] Specifically, in the present embodiment, in actual use, there may be two or more aeration sub-pipelines at the same time whose actual gas pressure value and the first preset pressure value have a difference greater than the set difference threshold and lasts for a certain period of time. At this time, if the gas injection amount is increased at the same time, the overall gas pressure will be reduced, which will not only fail to effectively prevent blockage, but is more likely to aggravate the blockage. Therefore, based on the number of aeration sub-pipelines whose actual gas pressure value and the first preset pressure value have a difference greater than the set difference threshold and lasts for a certain period of time, the operating power of the gas pressurizing device is adjusted to increase the operating power so that the gas pressure increases. Then, the flow regulating mechanisms corresponding to the two or more aeration sub-pipelines are adjusted to the second preset opening to ensure that the gas pressure meets the usage requirements, thereby ensuring the anti-blockage effect.

[0044] In another implementation, the above solution may also be replaced by: If the difference between the actual gas pressure value and the first preset pressure value of two or more aeration sub-pipes is greater than the set difference threshold and lasts for a long time, the aeration sub-pipes are controlled in sequence according to the preset numbers of the aeration sub-pipes (the control method is the same as above and will not be repeated here).

[0045] Further, adjusting the operating power of the gas pressurizing device includes: The operating power of the gas pressurizing device is calculated based on the following formula: ; in, is the operating power of the regulated gas pressurizing device; It is the reference operating power of the gas pressurizing device; The number of aeration sub-pipelines for which the difference between the actual gas pressure value and the first preset pressure value is greater than the set difference threshold and lasts for a certain period of time; is the total number of aeration sub-pipes; is the correction factor.

[0046] Specifically, the above calculation formula is used to calculate the operating power of the gas pressurizing device. The calculation result is accurate and can match the gas pressure, which can avoid overpressure, protect the pipeline, and ensure that the gas pressure meets the use requirements.
