Description

Technical Field

[0001] The invention relates to the technical field of gas pipelines, and in particular to a horizontal drainer and an automatic pollution cleaning control method thereof. Background Art

[0002] The horizontal drain of gas pipelines or equipment facilities is mainly used to remove condensed water, mechanical water and sewage in the pipelines or equipment. In daily operation, dust and impurities in the gas will be discharged together with the water, but some dust and impurities will be deposited in the cylinder of the horizontal drain. If the drain is not cleaned for a long time, it will cause blockage, making it impossible to drain the water in the gas pipeline, thereby increasing the pressure of the pipeline, increasing the pressure loss of the pipeline, and even causing major safety accidents such as collapse in severe cases. Therefore, the horizontal drain needs to be checked and cleaned regularly.

[0003] The inspection method of drainers in the prior art mainly relies on manually operating the valve and setting a fixed time for cleaning. However, the traditional manual cleaning method has safety hazards and low efficiency. Specifically, this method is not only labor-intensive, but also makes the cleaning staff stay in the area prone to gas leakage for a long time, and operating errors may cause poisoning. In addition, if the staff fails to clean and inspect the drainer on time due to poor management, it may also cause water accumulation in the gas pipeline or equipment facilities, thereby causing a series of safety accidents.

[0004] In order to solve the above problems, an embodiment of the present invention provides a horizontal drainer capable of automatically cleaning sludge. Summary of the invention

[0011] Detecting the turbidity of the liquid in the tank by using the turbidity meter to obtain a turbidity detection value;

[0012] If the turbidity detection value does not exceed the high turbidity threshold, the non-cleaning control logic of normal drainage is executed, specifically including: controlling the water in the gas U-shaped water seal to flow into the tank through the downcomer and then into the first water seal structure; wherein, if it is detected that the first water seal structure does not form a water seal, controlling the water replenishment structure to replenish water to the gas U-shaped water seal;

It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0022] Figure 1 The figure is a schematic diagram of a horizontal drainer provided by an embodiment of the present invention, and the horizontal drainer can be arranged in a gas pipeline. Figure 1 As shown, the drainer includes: a gas U-shaped water seal 10, a downcomer 20, a tank body 30, a first water seal structure 40, a second water seal structure 50, a water replenishment structure 60 and a sewage cleaning structure 70.

[0023] The gas U-shaped water seal 10 refers to a pipe in a horizontal drainer for discharging waste water and impurities in the gas pipeline out of the gas pipeline. For example, the gas U-shaped water seal 10 can be a U-shaped pipe, and both ends of the U-shaped pipe form a connecting vessel to prevent gas (such as coal gas) in the gas pipeline from leaking, and dust, coal slag and other sludge that cannot be discharged from the pipeline are accumulated at the low bend in the middle of the U-shaped pipe.

[0024] The downcomer 20 refers to a pipeline used to discharge sewage and accumulated sludge that penetrate into the low-position bending part of the gas U-shaped water seal 10 out of the gas U-shaped water seal 10 .

[0025] Specifically, the first end of the downcomer 20 is connected to the low bending part of the gas U-shaped water seal 10 , and the second end of the downcomer 20 is connected to the tank body 30 ; the first water seal structure 40 is connected to the tank body 30 .

[0026] The first end of the downcomer 20 refers to a port of the downcomer 20, which is connected to the low bending part of the gas U-shaped water seal 10, and can guide the sewage and sludge in the gas U-shaped water seal 10 into the downcomer 20. The second end of the downcomer 20 refers to another port of the downcomer 20, which is connected to the tank body 30, and can guide the sewage and sludge in the downcomer 20 into the tank body 30.

[0027] The tank body 30 refers to a tank-shaped container for storing sewage and sludge for subsequent treatment or discharge. The tank body 30 is usually made of corrosion-resistant materials, which can withstand the pressure and chemical corrosion of the liquid to ensure long-term safe use.

[0028] The first water seal structure 40 refers to a device that utilizes the water seal principle to prevent gas (such as coal gas) in the tank body 30 from leaking.

[0029] Specifically, the second water seal structure 50 is connected to the middle portion of the downcomer 20 ; and the water replenishment structure 60 is connected to the gas U-shaped water seal 10 .

[0030] The second water seal structure 50 is a device that uses the water seal principle to prevent gas (such as coal gas) in the downcomer 20 from leaking. The water replenishment structure 60 refers to a device for replenishing water into the coal gas U-shaped water seal 10. Specifically, since the coal gas pipeline contains harmful gas, the water in the pipeline will cause gas leakage after being discharged, which will cause a series of safety problems. Therefore, it is necessary to inject water into the pipeline in time to ensure safety.

[0031] The water replenishment structure 60 includes a primary water replenishment valve 61 and a secondary water replenishment valve 62. When the primary water replenishment valve 61 and the secondary water replenishment valve 62 are opened at the same time, the water replenishment structure 60 replenishes water into the gas U-shaped water seal 10.

[0032] Specifically, the cleaning structure 70 includes a turbidity meter 71, a cleaning component 72 and a cleaning pipeline. The turbidity meter 71 is used to detect the turbidity of the liquid in the tank body 30; the cleaning component 72 is located in the tank body 30 and is used to clean the bottom of the tank body 30; the cleaning pipeline is connected to the tank body 30 and is used to discharge the sewage after cleaning the tank body 30.

[0033] The turbidity meter 71 is an instrument for measuring the turbidity of a liquid, and is usually used to evaluate the cleanliness of the liquid by detecting the number and size of suspended particles in the liquid. In the embodiment of the present invention, the turbidity meter 71 is used to monitor the turbidity of the liquid in the tank 30 in real time to determine whether cleaning is required.

[0034] Exemplarily, the cleaning structure 70 performs the operation of cleaning and discharging sewage and sludge in the pipeline. The cleaning component 72 sprays water or a cleaning agent to the bottom of the tank body 30 to remove dirt and sediment at the bottom of the tank body 30. Specifically, the cleaning component 72 may include a nozzle or a nozzle installed on the side wall of the tank body 30. The cleaning pipeline connects the cleaning structure 70 and the tank body 30 to discharge the sewage generated during the cleaning process.

[0035] The horizontal drainer provided by the embodiment of the present invention has a gas U-shaped water seal 10 responsible for discharging sewage in the exhaust pipe, a downcomer 20 discharges sludge, sewage, etc. in the gas U-shaped water seal 10 into the tank body 30, and a dirt cleaning structure 70 cleans the dirt accumulated in the tank body 30. The first water seal structure 40 and the second water seal structure 50 can discharge sewage, and at the same time use the water seal to prevent gas leakage in the pipeline, and the water replenishment structure 60 is responsible for replenishing liquid into the pipeline to prevent water shortage in the pipeline. By connecting and cooperating with each other, the gas U-shaped water seal 10 can automatically clean the sludge accumulated in the gas U-shaped water seal 10 while discharging sewage inside the gas pipeline, and effectively prevent gas leakage, thereby improving the working efficiency and safety of the drainer.

[0036] Continue to see Figure 1 Optionally, a downcomer 20 is provided with a downcomer liquid level gauge 21, a water seal primary valve 22 and a water seal secondary valve 23; wherein the downcomer liquid level gauge 21 is located between the water seal primary valve 22 and the first end of the downcomer 20, and the water seal secondary valve 23 is located between the water seal primary valve 22 and the second end of the downcomer 20.

[0037] Among them, the downcomer level gauge 21 refers to an instrument for measuring the liquid level height of the liquid in the downcomer 20, which provides real-time liquid level information by monitoring the height of the liquid in the pipeline. The working principle of the downcomer level gauge 21 can be implemented in a variety of ways, including float type, pressure sensor, ultrasonic measurement, etc. Exemplarily, the downcomer level gauge 21 can be a magnetic flap level gauge. A float is installed inside the magnetic flap level gauge, and the float moves up and down with the change of the liquid level. The float has a built-in magnet and moves with the movement of the float. When the float rises or falls, the internal magnet affects the external flap, which is printed with different logos. When the liquid level is high, the flap is displayed as one logo; when the liquid level is low, it is displayed as another logo, thereby providing an intuitive liquid level indication.

[0038] The primary water seal valve 22 refers to a valve that uses the water seal principle to prevent the gas, liquid or solid medium in the pipeline from backflowing or leaking. The secondary water seal valve 23 refers to another valve that uses the water seal principle to prevent the gas, liquid or solid medium in the pipeline from backflowing or leaking.

[0039] In the embodiment of the present invention, the downcomer level meter 21 can monitor the liquid level of the liquid in the downcomer 20 in real time, and the water seal primary valve 22 and the water seal secondary valve 23 can prevent the leakage of the medium in the pipeline. In addition, by reasonably controlling the opening and closing sequence and opening and closing degree of the water seal primary valve 22 and the water seal secondary valve 23, the medium (such as sewage and / or sludge) flowing into the downcomer 20 can be controlled.

[0040] Optionally, the connection position between the second water seal structure 50 and the downcomer 20 is between the primary water seal valve 22 and the secondary water seal valve 23 .

[0041] Specifically, the primary water seal valve 22 is in an open state, and a small amount of liquid leaks from the low bending part of the gas U-shaped water seal 10 into the primary water seal valve 22. If the secondary water seal valve 23 is in a closed state at this time, the leaked liquid can only be discharged through the second water seal structure 50.

[0042] The technical solution of the embodiment of the present invention can realize efficient and safe liquid level monitoring and medium control by providing a combination of a downcomer liquid level meter 21, a water seal primary valve 22 and a water seal secondary valve 23. This solution not only improves the efficiency and safety of liquid management, but also provides reliable technical support for the horizontal drainer to discharge sewage and sludge inside.

[0043] Continue to participate Figure 1 Optionally, the second water seal structure 50 includes: an overflow pipe 51, an overflow liquid level gauge 52, a sewage sealing valve 53, a sewage sealing liquid level gauge 54, a sewage sealing pipe 55 and a first CO alarm 56; wherein, the first end of the overflow pipe 51 is connected to the middle part of the downcomer 20, the second end of the overflow pipe 51 is connected to the first end of the sewage sealing pipe 55 through the sewage sealing valve 53, and the first CO alarm 56 is arranged at the second end of the sewage sealing pipe 55; the overflow liquid level gauge 52 is located at the second end of the overflow pipe 51, and the sewage sealing liquid level gauge 54 is located at the top position of the sewage sealing pipe 55.

[0044] Continue to participate Figure 1 Optionally, the first water seal structure 40 includes a first water seal pipe 41, a low-level overflow liquid level gauge 42, a low-level overflow valve 43 and a second CO alarm 44; wherein, the first end of the first water seal pipe 41 is connected to the tank body 30, the low-level overflow valve 43 is located at the top of the first water seal pipe 41, and the low-level overflow valve 43 is located on the side of the low-level overflow valve 43 close to the first end of the first water seal pipe 41; the second CO alarm 44 is set at the second end of the first water seal pipe 41.

[0045] Exemplarily, the process of water in the gas U-shaped water seal 10 flowing into the second water seal structure 50 via the downcomer 20 is as follows: the water seal secondary valve 23 is closed, sewage flows into the downcomer 20 from the water seal primary valve 22 and begins to overflow to the overflow pipe 51 after accumulating to a certain height. The design purpose of this pipe is to prevent excessive accumulation of sewage in the downcomer 20 when the water seal primary valve 22 is closed, to ensure that the sewage can be discharged safely, and to avoid overflow or system failure.

[0046] The overflow level gauge 52 refers to an instrument for monitoring the liquid level in the overflow pipe 51. The working principle of the overflow level gauge 52 can be implemented in a variety of ways, including float type, pressure sensor, ultrasonic measurement, etc. Exemplarily, the overflow level gauge 52 can be a magnetic flap level gauge.

[0047] The sewage sealing valve 53 is a valve used to prevent sewage from flowing back when sewage is discharged. When the sewage sealing valve 53 is opened, the sewage in the overflow pipe 51 can flow into the sewage sealing pipe 55, thereby achieving sewage discharge in the pipe.

[0048] The sewage seal level gauge 54 refers to an instrument used to monitor the liquid level of sewage in the sewage seal pipe 55, and is usually used in conjunction with the sewage seal valve 53. The working principle of the sewage seal level gauge 54 can be implemented in a variety of ways, including float type, pressure sensor, ultrasonic measurement, etc. Exemplarily, the sewage seal level gauge 54 can be a magnetic flap level gauge.

[0049] Exemplarily, the sewage sealing pipe 55 is a U-shaped pipe. A U-shaped pipe refers to a pipe with a U-shaped structure, which uses the principle of a communicating vessel to maintain the balance of liquid on both sides of the pipe. When the sewage in the downcomer 20 flows into the sewage sealing pipe 55 through the sewage sealing valve 53, the liquid will rise in the U-shaped pipe to form a water seal. Under normal flow conditions, the liquid level in the pipe is maintained at a certain height to ensure that gas does not enter the pipe to prevent gas (such as CO) from leaking out.

[0050] The first CO alarm 56 refers to a device for detecting and monitoring the carbon monoxide concentration in the environment. When the carbon monoxide concentration exceeds the safety threshold, the first CO alarm 56 sends an alarm signal. Specifically, when the carbon monoxide concentration at the second end of the sewage seal pipe 55 exceeds the standard, the first CO alarm 56 sends an alarm signal.

[0051] The first water seal pipe 41 refers to a device in the first water seal structure 40 for preventing gas (such as CO) from overflowing. Specifically, the first water seal pipe 41 is filled with liquid (usually water or other liquids) to form a physical barrier for the gas. When the gas pressure in the pipe rises, the gas will be blocked by the liquid, thereby preventing the gas from leaking outward.

[0052] Among them, the low-level overflow liquid level gauge 42 refers to an instrument used to monitor when the liquid reaches a set low level in a storage tank or pipeline. The low-level overflow liquid level gauge 42 monitors the liquid level in real time through a float, a pressure sensor or ultrasonic technology. When the liquid level in the first water seal pipeline 41 drops to a preset low-level threshold, the low-level overflow liquid level gauge 42 will sound an alarm or trigger corresponding control measures. Exemplarily, the low-level overflow liquid level gauge 42 can be a magnetic flap liquid level gauge.

[0053] Among them, the low-level overflow valve 43 refers to a safety valve. When the low-level overflow liquid level gauge 42 detects that the liquid level is lower than a preset threshold, the low-level overflow valve 43 opens to allow the liquid to be discharged, thereby maintaining the liquid level in the first water seal pipe 41 within a safe range.

[0054] The second CO alarm 44 refers to another device for detecting and monitoring the carbon monoxide concentration in the environment. When the carbon monoxide concentration exceeds the safety threshold, the second CO alarm 44 sends an alarm signal. Specifically, when the carbon monoxide concentration at the second end of the first water seal pipe 41 exceeds the standard, the second CO alarm 44 sends an alarm signal.

[0055] In the embodiment of the present invention, the second water seal structure 50 can discharge the sewage deposited in the downcomer 20 through the sewage seal valve 53, and can monitor and prevent gas leakage in the pipeline. When the sewage seal valve 53 is closed, the wastewater cannot be discharged through the second water seal structure 50, and the wastewater gradually accumulates until the overflow level gauge 52 shows that the liquid level is higher than the set threshold. Under normal working conditions, the second water seal structure 50 forms an effective gas barrier through the water seal principle to ensure that the gas in the horizontal drain pipe does not leak out.

[0056] When the primary water seal valve 22 is opened, sewage and sludge flow into the tank 30 through the downcomer 20 and then into the first water seal structure 40. When the low-level overflow level gauge 42 in the first water seal structure 40 detects that the sewage in the first water seal structure 40 is higher than the set value, the low-level overflow valve 43 opens and discharges the wastewater. The first water seal structure 40 can not only prevent the liquid in the second water seal structure 50 from overflowing, but also ensure the safety and stability of the entire system.

[0057] The technical solution of the embodiment of the present invention not only effectively prevents gas leakage in the pipeline through the cooperation of the first water seal structure 40 and the second water seal structure 50, but also realizes efficient and safe discharge of sewage. The design of this solution takes into account safety, efficiency and maintenance convenience, and provides reliable technical support for the horizontal drainer to discharge sewage and sludge inside it.

[0058] Continue to see Figure 1Optionally, the cleaning component 72 includes a cleaning nozzle 73 and a water pump 74. The cleaning component 72 is located at the lower part of the side wall of the tank body 30. The water pump 74 is connected to the cleaning nozzle 73. A drain valve 75 is provided in the cleaning pipeline.

[0059] Among them, the cleaning nozzle 73 refers to the nozzle responsible for spraying the cleaning liquid to the bottom of the tank body 30. Exemplarily, the cleaning nozzle 73 is a fan-shaped high-pressure nozzle, which has high pressure and wide coverage, and can clean the sludge accumulated at the bottom of the tank body 30. The water pump 74 refers to a device for storing cleaning liquid (such as water or detergent), which can provide sufficient pressure and flow to transport the cleaning liquid (such as water or detergent) to the cleaning nozzle 73 to achieve effective cleaning. The drain valve 75 refers to a valve used to discharge sewage or dirt generated during the cleaning process. When the drain valve 75 is opened, the sewage and residue in the tank body 30 are discharged.

[0060] Figure 2 Flow chart of an automatic cleaning control method for a horizontal drain disclosed in an embodiment of the present invention. The method can be applied to any horizontal drain disclosed in the above embodiments, such as Figure 1-2 As shown, the automatic pollution cleaning control method includes:

[0061] S110, detecting the turbidity of the liquid in the tank body 30 by using the turbidity meter 71 to obtain a turbidity detection value.

[0062] The turbidity detection value refers to the value measured by the turbidity meter 71, which indicates the concentration and degree of suspended particles in the liquid. A higher turbidity detection value indicates that there are more suspended substances in the liquid, which may affect the safety and effectiveness of subsequent processing or use.

[0063] Specifically, by real-time monitoring of the turbidity of the liquid, the sludge content in the sewage of the gas U-shaped water seal can be discovered in time, providing a data reference standard for the subsequent cleaning process.

[0064] S120 , if the turbidity detection value does not exceed the turbidity high threshold, the non-cleaning control logic of normal drainage is executed, specifically including: controlling the water in the gas U-shaped water seal 10 to flow into the tank body 30 through the downcomer 20 and then into the first water seal structure 40 .

[0065] The turbidity high threshold refers to a standard value pre-set to determine whether the turbidity of the liquid is within an acceptable range. When the turbidity detection value of the liquid exceeds this threshold, the automatic cleaning device will take corresponding measures (such as opening the cleaning component 72). The non-cleaning control logic refers to the drainage operation performed when the turbidity detection value does not exceed the high threshold, which does not involve cleaning the pollutants in the water.

[0066] Specifically, if the turbidity detection value does not exceed the high turbidity threshold, it means that the concentration of sludge in the liquid is low and there is no need to perform the sewage cleaning process. At this time, the water seal secondary valve 23 is opened, and the sewage is introduced into the tank body 30 through the downcomer 20. Among them, the first water seal structure 40 can prevent the liquid in the tank body 30 from being too full and causing it to bear too much pressure, thereby improving the safety of the horizontal drainer.

[0067] Optionally, when controlling the water in the gas U-shaped water seal 10 to flow into the tank body 30 via the downcomer 20 and then into the first water seal structure 40, the component states of the horizontal drainer include: the downcomer liquid level gauge 21 of the downcomer 20 is at a low threshold, the water seal primary valve 22 of the downcomer 20 is open, the water seal secondary valve 23 is closed, the low-level overflow valve 43 of the first water seal structure 40 is open, and the low-level overflow liquid level gauge 42 of the first water seal structure 40 is at a high threshold.

[0068] S130 , otherwise, execute the normal drainage cleaning control logic, specifically including: controlling the water in the gas U-shaped water seal 10 to flow into the second water seal structure 50 via the downcomer 20 ; and controlling the cleaning component 72 to flush the tank body 30 .

[0069] If the turbidity detection value exceeds the high turbidity threshold, it means that the concentration of sludge in the liquid is high and a cleaning process is required. At this time, the sewage sealing valve 53 is opened to discharge the sewage from the second water seal structure 50, and the cleaning component 72 is opened to rinse the tank body 30 to ensure that the cleanliness of the tank body 30 meets the relevant specifications.

[0070] Optionally, the step of controlling the water in the gas U-shaped water seal 10 to flow into the second water seal structure 50 via the downcomer 20 includes:

[0071] The water seal primary valve 22 of the downcomer 20 is controlled to be opened and the water seal secondary valve 23 is controlled to be closed.

[0072] The water replenishment valve of the water replenishment structure 60 is controlled to open. If the downcomer liquid level gauge 21 of the downcomer 20 and the overflow liquid level gauge 52 of the second water seal structure 50 reach a high threshold, the sewage sealing valve 53 of the second water seal structure 50 is controlled to open.

[0073] If the sewage seal level gauge 54 of the second water seal structure 50 reaches a high threshold, the water replenishment valve of the water replenishment structure 60 is controlled to be closed.

[0074] The water supply valve includes a primary water supply valve 61 and a secondary water supply valve 62 .

[0075] Optionally, the step of controlling the cleaning component 72 to flush the tank body 30 includes: if the sewage seal level gauge 54 of the second water seal structure 50 reaches a high threshold, the water replenishment valve of the water replenishment structure 60 is in a closed state, and the first CO alarm 56 of the second water seal structure 50 has not alarmed, then the sewage valve 75 of the sewage cleaning pipe is controlled to open, and the water pump 74 of the cleaning component 72 is controlled to open so that the cleaning nozzle 73 cleans the sludge at the bottom of the tank body 30.

[0076] Among them, if the low-level overflow liquid level gauge 42 is at a low threshold and it is detected that the first water seal structure 40 has not formed a water seal, the water replenishment structure 60 is controlled to replenish water to the gas U-shaped water seal 10. When it is detected that the low-level overflow liquid level gauge 42 is at a high threshold, the water replenishment is stopped.

[0077] If it is detected that the second water seal structure 50 fails to form a water seal, the water replenishment structure 60 is controlled to replenish water to the gas U-shaped water seal 10 .

[0078] Specifically, since there is gas (mainly CO, which is toxic) in the gas pipeline, people may be poisoned. The horizontal drainer is connected to the gas pipeline. If the liquid in the horizontal drainer does not fill the entire pipeline to form a water seal, it may cause gas leakage, thereby threatening the life safety of people near the horizontal drainer. Therefore, it is necessary to detect in real time whether the first water seal structure 40 and the second water seal structure 50 have formed a tight water seal. Once it is found that the first water seal structure 40 or the second water seal structure 50 has not formed a water seal, it is necessary to replenish water into the gas U-shaped water seal 10 through the water replenishment structure 60 in time.

[0079] The automatic cleaning control method for the horizontal drainer provided in the embodiment of the present invention determines whether the corresponding cleaning steps need to be performed according to the turbidity of the liquid in the tank body 30 monitored, so as to ensure that the sludge inside the horizontal drainer can be discharged in time. At the same time, the water replenishing structure 60 replenishes water to the gas U-shaped water seal 10 to ensure the airtightness of the pipeline, prevent gas overflow, and ensure the safety of nearby personnel. This method not only improves the intelligence and automation of the horizontal drainer, but also effectively improves its safety during use.

[0080] Figure 3 This is a flow chart of another automatic cleaning control method for a horizontal drainer disclosed in an embodiment of the present invention. Based on the above-mentioned embodiment of the invention, the method includes:

[0081] S110, detecting the turbidity of the liquid in the tank body 30 by using the turbidity meter 71 to obtain a turbidity detection value.

[0082] S120 , if the turbidity detection value does not exceed the turbidity high threshold, the non-cleaning control logic of normal drainage is executed, specifically including: controlling the water in the gas U-shaped water seal 10 to flow into the tank body 30 through the downcomer 20 and then into the first water seal structure 40 .

[0083] S130 , otherwise, execute the normal drainage cleaning control logic, specifically including: controlling the water in the gas U-shaped water seal 10 to flow into the second water seal structure 50 via the downcomer 20 ; and controlling the cleaning component 72 to flush the tank body 30 .

[0084] S140, if the turbidity detection value is lower than the turbidity low threshold, the water pump 74 of the cleaning component 72 is controlled to be closed, the sewage discharge valve 75 of the sewage cleaning pipeline is controlled to be closed, the low-level overflow valve 43 of the first water seal structure 40 is controlled to be closed, and the water replenishment valve of the water replenishment structure 60 is controlled to be opened.

[0085] Specifically, when the turbidity value is low, it means that there is less sludge in the horizontal drain pipe, and no cleaning process is required. Turning off the water pump 74 can avoid unnecessary energy consumption. Opening the water supply valve can ensure that the water supply structure 60 can supply water to the pipe to ensure the airtightness of the pipe.

[0086] S150 , if the downcomer liquid level gauge 21 of the downcomer 20 reaches a high threshold, the water seal secondary valve 23 of the downcomer 20 is controlled to open.

[0087] Specifically, when the downcomer liquid level gauge 21 reaches a high threshold, it indicates that a large amount of water is stored in the downcomer 20 . At this time, the water seal secondary valve 23 is opened to allow water to flow into the tank body 30 .

[0088] S160: If the low-level overflow liquid level gauge 42 of the first water seal structure 40 reaches a high threshold, the low-level overflow valve 43 of the first water seal structure 40 is controlled to open.

[0089] Specifically, when the low-level overflow liquid level gauge 42 reaches a high threshold, it means that a large amount of water is stored in the first water seal structure 40 , and the low-level overflow valve 43 needs to be opened to discharge the water from the first water seal structure 40 .

[0090] The automatic cleaning control method for a horizontal drainer provided in an embodiment of the present invention controls the opening and closing of the valve by monitoring the turbidity detection value, the state of the downcomer liquid level meter 21 and the state of the low-level overflow liquid level meter 42, so that the horizontal drainer can automatically realize the process of drainage and water replenishment, thereby improving the automation level of the horizontal drainer and ensuring the safety of the horizontal drainer.

[0091] Optionally, the automatic pollution cleaning control method of the horizontal drainer also includes: water replenishment alarm control logic and CO alarm control logic.

[0092] The water replenishment alarm control logic includes: if the time for the water replenishment structure 60 to replenish water to the gas U-shaped water seal 10 exceeds the water replenishment time threshold, an alarm is issued.

[0093] The CO alarm control logic includes: if the monitoring value of the second CO alarm device 44 of the first water seal structure 40 reaches a high threshold, an alarm is issued; or if the monitoring value of the first CO alarm device 56 of the second water seal structure 50 reaches a high threshold, an alarm is issued.

[0094] The water replenishment alarm control logic is intended to ensure that the horizontal drain pipe structure is not damaged. If the water replenishment structure 10 replenishes water for too long, it may be due to leakage, blockage or other failures in the horizontal drain pipe, which needs to be repaired in time.

[0095] The CO alarm control logic is designed to ensure that carbon monoxide in the horizontal drain does not overflow. Once the carbon monoxide concentration at the pipe outlet exceeds the standard, an alarm signal is issued.

[0096] The automatic cleaning control method of various horizontal drainers provided in the embodiments of the present invention can be adapted to the horizontal drainers provided in any embodiment of the present invention, can realize the corresponding functional modules of the horizontal drainers and have corresponding beneficial effects.

[0097] It should be understood that the various forms of processes shown above can be used to reorder, add or delete steps. For example, the steps described in the present invention can be executed in parallel, sequentially or in different orders, as long as the desired results of the technical solution of the present invention can be achieved, and this document does not limit this.

[0098] The above specific implementations do not constitute a limitation on the protection scope of the present invention. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modification, equivalent substitution and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
