Description

Technical Field

[0001] This utility model relates to the field of process control, and more particularly to an online detection mechanism for the pH value of the influent to a paper tube base paper IC anaerobic reactor. Background Technology

[0002] With the continuous development of the paper industry, the IC anaerobic reactor, as a third-generation anaerobic reactor, is widely used in the paper wastewater treatment industry, especially in the paper tube base paper production industry. The main process flow of the wastewater treatment system is: collection tank → primary sedimentation tank → equalization tank → IC anaerobic reactor → aerobic tank → secondary sedimentation tank → external sewage discharge network. According to process requirements, the pH value of the influent to the IC anaerobic reactor needs to be monitored online, which is a key indicator for the operation of the anaerobic system. Typically, an online pH meter probe is inserted into the inlet pipe of an IC anaerobic reactor. However, due to the poor water quality and high suspended solids in the paper tube raw paper, the pH meter probe is frequently fouled. When the detection is inaccurate, the probe detection valve must be closed and the pH probe pulled out for cleaning. This results in frequent wastewater outflow at the wastewater treatment site, poor site hygiene, inconvenient operation, and increased workload for employees. Therefore, an online pH detection mechanism for the inlet water of a paper tube raw paper IC anaerobic reactor is proposed to solve the above problems. Utility Model Content

[0003] To overcome the above shortcomings, this utility model provides an online pH detection mechanism for the influent of a paper tube base paper IC anaerobic reactor. It aims to improve the problems in the existing technology where the paper tube base paper has poor water quality, high suspended solids, and the pH meter probe is often turbid, requiring the valve to be closed to clean the probe, resulting in wastewater overflow at the wastewater treatment site, poor hygiene, inconvenient operation, and increased workload.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: an online pH detection mechanism for the influent of a paper tube base paper IC anaerobic reactor, comprising a flowing water tank, a partition fixedly connected to the inner wall of the flowing water tank, a valve one located at the bottom of the flowing water tank on the left side of the partition, a drain pipe located at the bottom of the flowing water tank on the right side of the partition, a cover located at the top of the flowing water tank, a hole one opened on the surface of the cover, a hole two opened on the surface of the cover on the right side of the hole one, and a pipe one fixedly connected to the hole two; As a further description of the above technical solution: The end of pipe one away from hole two is fixedly connected to valve four, the end of valve four away from pipe one is fixedly connected to pipe two, the end of pipe two away from valve four is fixedly connected to valve three, and the end of valve three away from pipe two is fixedly connected to IC anaerobic water inlet pipe. As a further description of the above technical solution: The bottom of the flowing water tank is fixedly connected to a base; As a further description of the above technical solution: The partition is lower than the flowing water tank; As a further description of the above technical solution: The first pipe and the second pipe are connected; As a further description of the above technical solution: The second pipe is connected to the IC anaerobic water inlet pipe; As a further description of the above technical solution: Both hole one and hole two are located on the left side of the partition.

[0005] This utility model has the following beneficial effects: 1. In this utility model, by closing valve four and opening valve one, the probe and the flowing water tank can be easily rinsed, which effectively prevents the high suspended solids in the paper tube wastewater from contaminating and adhering to the probe, ensuring the long-term accuracy and stability of the pH meter probe measurement, and enhancing the reliability of the detection data.

[0006] 2. In this utility model, the sewage discharge path is cleverly designed in terms of structure. Whether it is the overflow generated by the baffle during online detection, or the residual wastewater and rinsing water discharged by opening valve one during cleaning and maintenance, all liquids containing suspended impurities are directly discharged into the aerobic tank through the closed sewage pipe or the outlet of valve one. This solves the drawbacks of wastewater overflow and site pollution in traditional cleaning methods, so that the work site can always be kept clean and meet the requirements of clean production. The simplified operation process reduces the workload of employees and improves maintenance efficiency. Attached Figure Description

[0009] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0010] Reference Figures 1-2 This utility model provides an embodiment of an online pH detection mechanism for the influent of a paper tube IC anaerobic reactor, comprising a flowing water tank 2. A partition 5 is fixedly connected to the inner wall of the flowing water tank 2, dividing the interior of the flowing water tank 2 into a detection zone and an overflow zone, thus forming an overflow structure that ensures a constant water level in the detection zone. A valve 3 is located at the bottom of the flowing water tank 2 on the left side of the partition 5. The valve 3 serves as a sewage control valve for the detection zone, which can be opened during cleaning to discharge wastewater and waste, thereby achieving non-landing cleaning and maintenance operations. A sewage pipe 4 is located at the bottom of the flowing water tank 2 on the right side of the partition 5. The sewage pipe 4 is used to continuously discharge wastewater overflowing from the detection zone, thereby ensuring the dynamic balance and uninterrupted operation of the system in online detection mode. A cover 6 is located at the top of the flowing water tank 2, covering the top of the flowing water tank 2. Its function is to provide an installation platform for the probe and pipe and prevent wastewater from splashing out, thereby ensuring operational safety and reliability. To ensure the cleanliness of the testing area, the surface of the cover 6 has a hole 7, which is specifically used to install the online pH meter probe, allowing it to be stably placed in the water sample in the testing area for accurate measurement. To the right of hole 7, the surface of the cover 6 has a hole 8, which serves as the inlet for the wastewater sampling pipe, connecting to pipe 9 to accurately guide the water sample from the main pipe into the testing area. A base 1 is fixedly connected to the bottom of the flow tank 2, fixing and supporting the entire flow tank 2. Its function is to raise the device to a suitable height, facilitating daily inspections and maintenance by operators. The partition 5 is lower than the flow tank 2, and the height difference is designed as an overflow weir, allowing automatic overflow when the water level in the testing area reaches a specific height, ensuring a constant pH probe detection water level. Holes 7 and 8 are both located to the left of the partition 5. This layout ensures that the inlet water and the pH probe are both within the same testing area, guaranteeing that the probe measures an unmixed, up-to-date, representative water sample.

[0011] Reference Figures 1-2One end of pipe 19, away from orifice 28, is fixedly connected to valve 410. Valve 410 serves as a key control valve on the inlet pipe, which can be closed to cut off the wastewater source when cleaning is required. The other end of valve 410, away from pipe 19, is fixedly connected to pipe 211. Pipe 211 connects valve 312 and valve 410, forming the main part of the sampling pipeline. The other end of pipe 21, away from valve 410, is fixedly connected to valve 312. Valve 312, as a normally open sampling valve installed on IC anaerobic inlet pipe 13, is used to draw water samples from the main process flow, thereby providing a continuous and stable water source for the online monitoring system. Valve 312 is located at... One end of pipe 2 11 is fixedly connected to IC anaerobic inlet pipe 13. IC anaerobic inlet pipe 13 is the main process pipeline served by this device. The device directly takes samples from this pipeline, thereby ensuring that the measured pH value can truly reflect the process water quality. Pipe 1 9 is connected to pipe 2 11. The two are connected in a controllable manner through valve 4 10, forming a complete inlet pipeline from the sampling point to the flow tank 2. Pipe 2 11 is connected to IC anaerobic inlet pipe 13. The two are connected through valve 3 12, which serves to establish an independent bypass sampling channel, thereby achieving effective separation of online detection and the main process flow without interference.

[0012] Working Principle: During normal operation, a portion of the wastewater in the IC anaerobic inlet pipe 13 flows continuously into the left side area of ​​the flow tank 2 through the normally open sampling valve 12 and the open control valve 10, via pipes 11 and 9. This area is separated by a partition 5, forming a detection zone. The online pH meter probe is inserted into this detection zone to a specific depth through hole 7 on the cover 6 to measure the pH value of the flowing wastewater sample in real time. As wastewater is continuously injected, the water level in the detection zone gradually rises. When the level exceeds the height of the partition 5, the wastewater automatically overflows to the overflow zone on the right side of the partition 5, and is then discharged directly into the aerobic tank through the drain pipe 4 at the bottom of the overflow zone. This design ensures that the pH meter probe is always immersed in a representative fresh water sample, while maintaining a constant water level in the detection zone. To ensure the continuity and accuracy of the detection, and to prevent high suspended solids in the paper tube wastewater from contaminating the probe, operators regularly clean the device. First, valve 410 is closed to cut off the entry of wastewater samples. Then, valve 3 at the bottom of the detection area is opened to directly discharge the residual wastewater and deposited dirt into the aerobic tank, avoiding a messy environment. Next, operators can thoroughly rinse the inner wall of the detection area and the pH meter probe through an external clean water pipe. The wastewater after cleaning is also discharged through valve 3. After cleaning, valve 3 is closed and valve 410 is reopened, and the device immediately returns to continuous online detection mode. This entire process cleverly separates pH detection from cleaning and maintenance, ensuring the long-term reliability of measurement data, achieving clean and convenient operation, and improving work efficiency and the quality of the on-site environment.
