Description

Technical Field

[0001] This utility model relates to the technical field of water quality analysis equipment, specifically to a multi-channel adaptive filtration system for water quality analysis pretreatment. Background Technology

[0002] In the field of water quality monitoring and analysis, the pretreatment system is a crucial component ensuring the accurate operation of water quality analyzers. Existing water quality analysis pretreatment systems typically employ a fixed-flow filtration design, which has the following significant drawbacks: 1. Low filtration efficiency: Regardless of changes in influent water quality, a fixed number of filtration stages and pore size are used, leading to over-filtration when water quality is good, increasing system pressure loss and energy consumption; 2. Short consumable lifespan: Fine filtration units are constantly in operation, continuously subjected to water flow impacts even when water quality is good, resulting in frequent filter replacements and high maintenance costs; 3. Poor adaptability: The filtration strategy cannot be dynamically adjusted according to influent water quality, making it difficult to guarantee pretreatment effectiveness when water quality deteriorates, affecting the measurement accuracy of the downstream analyzer; 4. High energy consumption: Under fixed operating conditions, the pump and filtration units operate continuously at full load, causing unnecessary energy waste. Utility Model Content

[0003] The purpose of this invention is to provide a multi-channel adaptive filtration system for water quality analysis pretreatment. By monitoring the influent water quality in real time and intelligently switching the filtration path, it achieves efficient filtration, energy saving and consumption reduction, and extends the life of consumables, ensuring that the back-end analyzer obtains stable and qualified water samples.

[0004] The technical solution adopted in this utility model is: a multi-channel adaptive filtration system for water quality analysis pretreatment, including a sampling tube and a controller; the input end of the sampling tube is provided with a water quality monitoring module connected to the controller, and the output end of the sampling tube is provided with a multi-stage filtration module and a bypass component; the multi-stage filtration module includes at least two filters arranged in series, and the pore size of the filters decreases sequentially from the input end to the output end of the multi-stage filtration module; the bypass component includes a bypass pipe arranged in parallel with each filter, and the input end of the bypass pipe is connected to the input end of the filter through an electromagnetic switching valve, and each electromagnetic switching valve is connected to the controller.

[0005] In this technical solution, the filtration system is used to filter the water sample input to the water quality analyzer. This system can adaptively filter according to the water quality. When the water sample is input from the sampling tube, it first passes through the water quality monitoring module to detect the water quality. The controller module controls the electromagnetic switching valve according to the actual water quality, thereby intelligently adjusting the filtration path. When the water quality is poor, the bypass pipe is closed to allow the water sample to undergo multi-stage fine filtration. When the water quality is good, the corresponding bypass pipe is connected to reduce consumable consumption. This achieves efficient filtration, energy saving and consumption reduction, and extended consumable life, ensuring that the downstream water quality analyzer obtains stable and qualified water samples.

[0006] Preferably, the multi-stage filtration module includes at least two of the following: a coarse filtration module, a fine filtration module, an ultrafiltration module, and a nanofiltration module.

[0007] Preferably, the input end of the sampling tube is detachably connected to a sampling connector.

[0008] Preferably, the bypass pipe is provided with quick-release connectors at both ends.

[0009] Preferably, the bypass pipe is equipped with a one-way valve.

[0010] The beneficial effects of this utility model are: this utility model collects in-water turbidity, COD and other indicators in real time through a water quality monitoring module; the controller automatically switches the filtration path according to preset multi-level thresholds; unnecessary fine filtration is reduced through bypass components, and the filter element is prevented from clogging prematurely due to excessive interception of suspended solids; the intelligent switching of water quality detection status improves the service life of the filter element and reduces the energy consumption of equipment operation; it has high practical value.

[0014] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0015] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0016] like Figure 1As shown in the figure, a specific embodiment of this utility model provides a multi-channel adaptive filtration system for water quality analysis pretreatment. The filtration system is used to filter water samples input to a water quality analyzer. The system can adaptively filter according to water quality. Specifically, it includes a sampling tube 100 and a controller 200. The input end of the sampling tube 100 is provided with a water quality monitoring module 300 that is signal-connected to the controller 200. The output end of the sampling tube 100 is provided with a multi-stage filtration module and a bypass component. The multi-stage filtration module includes at least two filters 400 arranged in series. The pore size of the filters 400 decreases sequentially from the input end to the output end of the multi-stage filtration module. The bypass component includes a bypass pipe 500 arranged in parallel with each filter 400. The input end of the bypass pipe 500 is connected to the input end of the filter 400 through an electromagnetic switching valve 600. Each electromagnetic switching valve 600 is signal-connected to the controller 200.

[0017] like Figure 1 As shown, through the above settings, in this embodiment, the adaptive filtration system provides that when the water sample is input from the sampling tube 100, it first passes through the water quality monitoring module 300 to detect the water quality. The controller 200 module controls the electromagnetic switching valve 600 according to the actual water quality, thereby intelligently adjusting the filtration path. The water quality monitoring module 300 integrates a turbidity sensor (model: HACH2100Q, measurement range 0-1000NTU, accuracy ±2%) and a COD fast sensor (model: HACH DR3900, measurement range 0-1000mg / L, response time <30s), which is installed at the input end of the sampling tube 100 and communicates with the controller 200 in real time through an RS485 interface.

[0018] like Figure 1 As shown, in practical implementation, the system collects influent turbidity, COD, and other indicators in real time through the water quality monitoring module 300. The controller 200 automatically switches the filtration path according to preset multi-level thresholds (e.g., fine filtration is activated when turbidity > 10 NTU, and ultrafiltration is activated when turbidity > 50 NTU). For example, when the water quality is good (turbidity < 5 NTU), the controller 200 closes the bypass valve of the fine filtration module and only activates the coarse filtration module; when the water quality deteriorates, the coarse filtration + fine filtration + ultrafiltration modules are connected in series to ensure that the effluent turbidity ≤ 1 NTU, meeting the influent requirements of the high-precision analyzer. In practical applications, the multi-stage filtration module includes at least two of the following: coarse filtration module, fine filtration module, ultrafiltration module, and nanofiltration module.

[0019] Made of corrosion-resistant UPVC material, with a pipe diameter of DN25, the inlet end connects to the water inlet pipe, and the outlet end branches out to a multi-stage filtration module and bypass assembly. The inner wall of the sampling tube 100 is smooth, and the flow velocity is controlled at 0.5-1m / s to avoid water sample sedimentation. For easy connection of the sampling assembly, the inlet end of the sampling tube 100 is detachably connected to a sampling connector 700.

[0020] like Figure 1 As shown, this embodiment has quick-release connectors at both ends of the bypass pipe 500 for easy disassembly and replacement. At the same time, the bypass pipe 500 is equipped with a one-way valve 800 to ensure unidirectional flow of water samples. The bypass pipe 500 is made of UPVC material, and an electromagnetic switching valve 600 (model: SMC VX3120, voltage DC24V, response time <100ms) is installed at the pipe input end. The valve port is aligned with the inlet and outlet of each stage of the filter module to ensure that there are no dead angles in the water flow.

[0021] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
