It should be understood that the specific examples described herein are only used to explain the application, and are not used to limit the application.

[0026] Before describing the various embodiments of the present application in detail, the technical concept of the present application will be briefly described first: Currently, when cleaning scale deposits in pipelines, the pipeline to be cleaned is usually isolated, that is, the leachate is stopped from being transported, and online cleaning cannot be achieved, which greatly affects the operating efficiency. To this end, the leachate pipeline scale cleaning system provided by the present application is provided with a dual-branch alternating water flow module and two cleaning pipelines.

This can ensure the normal transmission process of the leachate and realize online cleaning of some branches without stopping the transmission of leachate, thereby ensuring operating efficiency. The specific principles of the leachate pipeline scale cleaning system of the present application will be described below in conjunction with more embodiments.

The rotating water flow module includes an inlet main pipe 1, an outlet main pipe 2, a first branch pipe 5, and a second branch pipe 6. The two ends of the first branch pipe 5 are connected to the inlet main pipe 1 and the outlet main pipe 2, and the two ends of the second branch pipe 5 are connected to the inlet main pipe 1 and the outlet main pipe 2; the washing liquid circulation module includes a first cleaning pipeline and a second cleaning pipeline. The two ends of the first cleaning pipeline are connected to the two ends of the first branch pipe 5, and the two ends of the second cleaning pipeline are connected to the two ends of the second branch pipe 6. The washing liquid supply module is used to provide cleaning liquid to the first cleaning pipeline and the second cleaning pipeline.

[0028] In one or more embodiments, the washing liquid circulation module further includes a washing liquid tank 14, to which both the first and second washing pipelines are connected. Washing liquid tank 14 is used to store the washing liquid provided by the washing liquid supply module. Exemplarily, the washing liquid circulation module further includes a circulation pipeline 20, which connects the washing liquid tank 14, the first and second washing pipelines. The circulation pipeline 20 transports washing liquid from the washing liquid tank 14 to the first and second washing pipelines, where it cleans the first and second branch pipes 5, 6, before returning to the washing liquid tank 14, achieving cyclic cleaning.

[0029] Illustratively, the first cleaning pipeline includes a first pipe segment 11 and a second pipe segment 22. The two ends of the first pipe segment 11 are respectively connected to one end of the first branch pipe 5 and the circulation pipeline 20, and the two ends of the second pipe segment 22 are respectively connected to the other end of the first branch pipe 5 and the circulation pipeline 20. The second cleaning pipeline includes a third pipe segment 12 and a fourth pipe segment 23. The two ends of the third pipe segment 12 are respectively connected to one end of the second branch pipe 6 and the circulation pipeline 20, and the two ends of the fourth pipe segment 23 are respectively connected to the other end of the second branch pipe 6 and the circulation pipeline 20.

The other section of the circulation pipe section is located below the washing liquid tank 14 and connected with the washing liquid tank 14 and the second three-way valve 21 at both ends, and the circulation pump is installed on the section of the circulation pipe section, so that the cleaning liquid in the washing liquid tank 14 can be delivered to the second pipe section 11 and the fourth pipe section 23.

The washing liquid in the washing liquid tank 14 flows through the second pipe section 22, the first branch pipe 5, the first pipe section 11 and the washing liquid tank 14 in sequence through the circulation pump, completing the circulation cleaning and realizing the delivery of the leachate at the same time. Similarly, the second branch pipe 6 can also be cleaned, and the first branch pipe 5 can be used to deliver the leachate at the same time.

[0033] Exemplarily, the leachate pipeline fouling cleaning system further comprises a cleaning object filtering and collecting device arranged on the upper part of the washing liquid tank 14. The bottom of the collecting device is a filter screen, which is responsible for filtering the fouling objects and sludge in the washing liquid and collecting the fouling objects falling off during the cleaning process. After the cleaning objects are collected, they are regularly transported to a waste incineration pit for secondary incineration treatment, avoiding the occurrence of secondary pollution.

[0034] In one or more embodiments, the washing solution supply module includes a clean water collection tank 16, a clean water supply pipe 15, an acid solution tank 19, and an acid solution supply pipe 18. The acid solution supply pipe 18 is connected to the clean water collection tank 16 and the washing solution tank 14, and the acid solution supply pipe 18 is connected to the acid solution tank 19 and the washing solution tank 14.

The clean water collection tank 16 collects clean water from the factory raw water supply or the leachate treatment system clean water tank. The clean water is supplied to the washing solution tank 14 through the clean water supply pipe 15. A submersible pump is built into the clean water collection tank 16 or a supply pump is installed on the clean water supply pipe to serve as a clean water supply power source. The flow rate is 1-80 m 3 / h. The acid solution tank 19 contains acid such as citric acid or hydrochloric acid, which is used as a raw acid solution. The acid concentration ratio is 40%-80%.

The volume of the washing solution tank 14 is 2-8 times the volume of the pipeline to be cleaned. The washing solution tank 14 is equipped with a pH meter and a liquid level meter. The pH meter is corrosion-resistant, with a range of 0-16.00 and an accuracy of 0.01-0.1. The power supply voltage is 100-240 V. The liquid level meter is corrosion-resistant and can be a float-type liquid level meter, a capacitive liquid level meter, or an ultrasonic liquid level meter.

The first ultrasonic pipeline descaler 7 is installed on the first branch pipe 5, and the second ultrasonic pipeline descaler 8 is installed on the second branch pipe 6.

[0037] The ultrasonic pipeline descalers 7 and 8 are, for example, arranged at positions where the pipeline bends significantly (see Figure 1 dotted lines) or fixed to the pipeline to be cleaned at 1 / 4-3 / 4 of the length. They use ultrasonic and vibration principles to prevent scaling and make scaling substances fall off. The vibration frequency of the ultrasonic pipeline descalers is 200-20000 Hz, and the working temperature is -20℃ to 100℃. They use high-frequency vibration or high-frequency pulse vibration principles. The coordinated shock waves can penetrate deep into the pipeline and effectively remove scaling substances attached to the pipeline wall.

[0038] Exemplarily, the electromagnetic scale inhibitor is arranged on the pipe bend, horizontal pipe or vertical pipe in the form of electromagnetic coil. Through electromagnetic principle, the coil passes through variable frequency direct current or pulse current, so that the scale forming substance is not easy to adhere to the pipe wall, and the deposition speed of the easy scale forming substance is reduced. The electromagnetic scale inhibitor should include (but not limited to) copper wire, AC / DC converter, control system and safety device. The copper wire should be wrapped with appropriate insulating material to prevent accidental electric shock. The AC / DC converter includes rectifier and filter, which converts alternating current into smooth direct current. The control system includes current regulator, integrated current sensor and microcontroller, which is used to control the intensity and time of the current to ensure safety and efficiency. The safety device includes overload protection, short circuit protection and leakage protection.

[0039] Exemplarily, the control system can be provided to control the start of the circulating pump, the ultrasonic pipe descaler, the electromagnetic scale inhibitor and the valve switching. The start and stop of the delivery pump and the residence time of the cleaning liquid can be controlled according to the pH condition in the pipe cleaning tank, so as to achieve the corresponding cleaning effect. The cleaning methods include water circulation cleaning, cleaning liquid circulation cleaning and cleaning liquid standing and circulation cleaning. Among them, (1) high-flow water circulation cleaning: the concentration of the washing liquid in the washing liquid supply system is controlled, the water is used as the cleaning medium, and the high-flow water is delivered to the pipe through the circulation system to flush the inside of the pipe and remove the surface dirt, sludge and other impurities. (2) Cleaning liquid circulation cleaning: the concentration of the washing liquid in the washing liquid supply system is controlled, the low-concentration acidic washing liquid is used as the cleaning medium, and the cleaning liquid is delivered to the cleaning area through the circulation system to remove the short-term deposited sludge and dirt through chemical and physical dual action. (3) Cleaning liquid standing and circulation cleaning: the concentration of the washing liquid in the washing liquid supply system is controlled, the high-concentration acidic washing liquid is used as the cleaning medium, the washing liquid is filled into the cleaning pipe for a period of time to allow the washing liquid to fully penetrate and decompose the stains, and then the object after soaking is circulated and washed to remove the long-term deposited stubborn dirt.

[0040] In one or more embodiments, as shown in Figure 2 The leachate pipe scale cleaning system further includes a backwashing pipeline, two ends of the backwashing pipeline being communicated with the clean water supply pipe 16 and the water inlet main pipe 1. The backwashing pipeline includes a backwashing pipe 29, a three-way valve 28 and a pneumatic / electromagnetic valve 30, two ends of the backwashing pipe 29 being communicated through the three-way valve 28 and the pneumatic / electromagnetic valve 30 respectively.

A three-way valve 28 is installed at the outlet of the pump to switch the flushing water pipeline. The backwashing pipeline is connected to the inlet end of the influent pipe 1, and a pneumatic / electric valve 30 is installed at the connection interface.

[0041] The leachate pipeline scaling cleaning system and control method provided by the embodiment have the following technical effects:

[0042] 1. The cleaning system controls the water inlet and outlet of the system based on the manifold system, and switches the pipeline by cooperating with the inlet three-way valve and the outlet three-way valve, so that the leachate flows through different pipelines, thereby realizing online cleaning without stopping the operation of the leachate system. The pain point that the system cannot be stopped for cleaning in summer when the leachate water volume is large is solved.

[0043] 2. The cleaning system is based on the main cleaning method of pickling and high-flow flushing. At the pipeline bending part, the ultrasonic descaler or electromagnetic scale inhibitor is cooperated to make the scaling substances fall off at the pipeline bending part through the principles of ultrasonic and vibration and electromagnetic, greatly improving the cleaning efficiency and effect. And during the operation of the leachate system (when not cleaning), the ultrasonic descaler or electromagnetic scale inhibitor is arranged to make the pipeline bending part not easy to scale, reduce the deposition speed of the scaling substances, and make part of the scaling substances fall off, reducing the pipeline cleaning frequency.

[0044] 3. The control system of the cleaning system can control the start and stop of the delivery pump according to the pH value in the pipeline cleaning tank, and the residence time of the cleaning liquid, so as to achieve the corresponding cleaning effect. In operation, by controlling the concentration ratio of the washing liquid in the washing liquid supply system, using clean water or acid as the cleaning medium, high-flow clean water circulation cleaning, cleaning liquid circulation cleaning, and cleaning liquid standing and circulation cleaning are carried out. Gradient cleaning during operation is realized, avoiding waste of chemicals and reducing equipment wear and tear. At the same time, the system is easy to operate, safe and reliable, and will not cause damage to the pipeline and equipment, reducing maintenance cost and improving the operation efficiency of the leachate treatment system.
