Description

Technical Field

[0001] This invention belongs to the field of water treatment technology, specifically relating to a multi-functional automatic control circulating water treatment machine, which is suitable for industrial circulating cooling water systems, central air conditioning circulating water systems and other scenarios, and can realize the full-process automation of circulating water treatment. Background Technology

[0002] During long-term operation, circulating water systems are prone to scale buildup in heat exchangers and corrosion, leading to reduced heat exchange efficiency, impacting production efficiency and equipment lifespan. Furthermore, the consistently high water temperature (25℃-35℃) in circulating water systems easily fosters the growth of bacteria, algae, and other microorganisms. These microorganisms mix with silt and dust in the system to form biofilm, which adheres to the heat exchangers, causing scale buildup and accelerating corrosion. Maintaining system stability requires the use of water treatment agents or equipment. Existing circulating water treatment equipment has several shortcomings: First, its functions are relatively limited, with most devices only capable of single functions such as scale inhibition, sterilization, or corrosion inhibition, requiring multiple devices to be used in combination, resulting in complex system installation and a large footprint. Second, the control methods are outdated, with operations such as flow regulation and electrode cleaning relying heavily on manual intervention, making it difficult to dynamically adjust according to real-time operating conditions, resulting in low treatment accuracy. Third, water resources are wasted significantly, as the scale-containing wastewater generated during electrode cleaning in equipment that uses electrode adsorption to soften water is mostly discharged directly without being reused. Fourth, there is a lack of full-process linkage control, with each treatment stage operating independently, failing to respond promptly to abnormal parameters, thus affecting treatment effectiveness. Fifth, some equipment relies on chemical agents, which can easily cause secondary pollution of water bodies, and the dosage of these agents is difficult to control precisely, posing a risk of waste or failure.

[0003] To address the aforementioned issues, there is an urgent need for a circulating water treatment machine that integrates multiple processing functions, has a high degree of automation, high water resource utilization, and requires no chemical reagents, in order to meet the requirements of efficient, environmentally friendly, and stable operation of circulating water systems.

Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0019] The multifunctional automatic control circulating water treatment machine of the present invention consists of an automatic control system and an integrated water treatment body. The two work together to complete the entire process of circulating water treatment. The specific technical solution is as follows: The automatic control system adopts a modular design, undertaking the core functions of "signal acquisition - logic operation - action driving", including a signal acquisition module, a main control module, and an actuator module: Signal acquisition module: As an operating condition monitoring unit, it includes a first pressure gauge corresponding to the bag filter 8, a second pressure gauge corresponding to the filter 6, a third pressure gauge corresponding to the cleaning tank 7, a voltage sensor corresponding to the control system power supply of the reactor 5, a first flow meter 3 corresponding to the first treatment branch, a second flow meter 11 corresponding to the second treatment branch, and a pressure detection element for the main outlet pipeline 2; each sensor and flow meter collects pressure, voltage, and flow parameters in real time, and sends the data to the main control module through the signal transmission unit to ensure that the operating condition data is updated in real time.

[0020] Main control module: As the core computing unit, it has a built-in preset threshold storage unit, timing control unit and logic judgment unit; the preset threshold storage unit stores the normal operating range of each parameter, such as voltage threshold, pressure threshold and flow threshold; the logic judgment unit compares the collected real-time parameters with the preset thresholds and generates control commands; the timing control unit controls the action sequence of the actuator module to avoid system failures caused by disordered actions.

[0021] Actuator module: As the action execution unit, it includes inlet valve 4, first valve 12, filter 6 outlet valve, reactor 5 drain valve, bag filter 8 outlet valve, bag filter 8 drain valve, cleaning pump, reuse pump, solenoid coil 10, metal electrode assembly, electrocatalytic electrode assembly, check valve 13, and corresponding drive unit; the drive unit receives instructions from the main control module and drives each component to perform precise actions, such as valve opening adjustment, pump start and stop, electrode electrolysis control, etc.

[0022] The integrated water treatment unit adopts a structural layout of "two parallel / series selectable + closed-loop cleaning + anti-backflow", avoiding the installation complexity of multiple equipment combinations. Each structure corresponds one-to-one with the control logic of the automatic control system. The basic diversion structure includes a main inlet valve, main pipe 1, main outlet pipe 2, check valve 13, and main outlet valve. The main inlet valve enables the initial diversion of circulating water, allowing the water flow to be distributed in parallel to the first and second treatment branches based on water hardness, or connected in series so that the water flows through the first treatment branch before entering the second treatment branch. Main pipe 1 is used to merge the two treated water streams, ensuring uniform mixing. Main outlet pipe 2 is the transport channel for the merged water flow, and check valve 13 is connected in series in main outlet pipe 2 to prevent backflow caused by pressure fluctuations. The main outlet valve controls the output of the treated circulating water. The overall structure is compact, reducing the number of pipe connection nodes.

[0023] The first treatment branch and closed-loop cleaning system: The first treatment branch is sequentially equipped with a first flow meter 3, an inlet valve 4, a reactor 5, a filter 6, and an outlet valve of the filter 6 along the water flow direction; the anode and cathode plates are arranged in parallel inside the reactor 5, and the anode and cathode plates are respectively connected to the positive and negative terminals of the control system power supply. The polarity of the plates can be switched, and water softening and calcium and magnesium ion adsorption are achieved through oxidation-reduction reaction; the filter 6 is used to intercept impurities and reaction products in the water to ensure that the water flow is clean before merging; the closed-loop cleaning system is matched with the reactor 5, including a cleaning tank 7, a cleaning pump, a reuse pump, a bag filter 8, a high-pressure nozzle, a water supply pipe 9, and related valves. The high-pressure nozzle is fixed to the inner wall of the reactor 5 and can perform all-round flushing of the anode and cathode plates. The bag filter 8 realizes solid-liquid separation of scale-containing wastewater. The reuse pump transports the separated clean water back to the cleaning tank 7. One end of the water supply pipe 9 is connected to the main water inlet valve and the other end is connected to the cleaning tank 7 to realize automatic water supply to the cleaning tank 7, forming a closed-loop cleaning water circuit.

[0024] The second treatment branch is arranged sequentially along the water flow direction, including an electromagnetic coil 10, a second flow meter 11, a first valve 12, a metal electrode assembly, and an electrocatalytic electrode assembly. The electromagnetic coil 10 is equipped with a shield to prevent electromagnetic interference to the outside world. The electromagnetic coil 10 can perform high-frequency oscillation treatment on the water. The metal electrode assembly is fixed by an electrode bracket and can be made of aluminum, zinc, or copper according to requirements. It releases corresponding metal ions through electrolysis to achieve flocculation, corrosion inhibition, or algae suppression. The electrode surface of the electrocatalytic electrode assembly is coated with a catalyst. An electric field is applied through an external electric field control unit to catalyze the chloride ions in the water to generate strong oxidizing substances, thereby enhancing the sterilization effect. The entire branch pipeline is made of corrosion-resistant materials to extend the service life of the equipment.

[0025] Auxiliary structures: The top of the cleaning tank 7 is equipped with an automatic suction and exhaust valve to balance the pressure inside the tank; the filter bags inside the bag filter 8 are removable and replaceable for easy maintenance; all pipe connections are sealed to prevent water leakage; the bottom of the equipment is equipped with a mounting bracket for easy fixed installation; both reactor 5 and cleaning tank 7 are equipped with exhaust and water blocking valves to ensure safe operation of the equipment.

[0026] Normal water treatment process: The circulating water enters the equipment through the main inlet valve. The signal acquisition module starts to collect various parameters. The main control module starts the two-way flow control. Based on the signals from the first flow meter 3 and the second flow meter 11, the opening of the inlet valve 4 and the first valve 12 are adjusted to distribute the two water flow ratios. First treatment branch: Water flows into reactor 5 after being measured by the first flow meter 3. The anode and cathode plates operate under the power of the control system. The main control module monitors the electrode status through the voltage sensor and adjusts the opening of the inlet valve 4 according to the signal of the second pressure gauge. The treated water flows through filter 6 and flows into the main pipeline 1 through the outlet valve of filter 6. Second processing branch: Water flows through electromagnetic coil 10, and the main control module controls electromagnetic coil 10 to start; the activated water flows through second flow meter 11 for measurement, and the flow rate is regulated by first valve 12 before flowing through metal electrode assembly, and the main control module controls metal electrode assembly to electrolyze; then the water flows through electrocatalytic electrode assembly, and the main control module applies an electric field through electric field control unit; the treated water flows into main pipe 1. The two water streams converge at the main pipeline 1. The main control module controls the check valve 13 to open based on the pressure signal from the main outlet pipeline 2. The converged water then flows through the main outlet valve to the circulating water system.

[0027] Electrode cleaning process: When the anode and cathode plates in reactor 5 reach adsorption saturation, the power supply voltage of the control system drops below the preset threshold, and the voltage sensor transmits the signal to the main control module to trigger a cleaning command. The main control module controls according to a time sequence: first, it closes the inlet valve 4 and the outlet valve of the filter 6 to cut off the normal water flow of the first treatment branch; then it opens the drain valve of the reactor 5 and the outlet valve of the bag filter 8 to connect the cleaning pipeline; finally, it starts the cleaning pump and the reuse pump. The cleaning pump draws water from the cleaning tank 7 and rinses the anode and cathode plates with a high-pressure nozzle. The scale-containing wastewater flows into the bag filter 8 through the drain valve of the reactor 5. The main control module closes the drain valve of the bag filter 8 if the pressure exceeds the threshold according to the signal of the first pressure gauge. The separated clean water is transported back to the cleaning tank 7 by the reuse pump. Based on the signal from the third pressure gauge, if the pressure in the cleaning tank 7 exceeds the threshold, the main control module stops the reuse pump and automatically releases pressure via the suction and exhaust valves. When the voltage returns to the preset threshold, the main control module stops the cleaning pump and reuse pump in sequence, closes the relevant valves, and opens the inlet valve 4 and the outlet valve of the filter 6 to restore normal water treatment.

[0028] The automatic control system in this invention also includes a data processing unit and a hierarchical early warning unit. The data processing unit is electrically connected to the signal acquisition module and the main control module. The hierarchical early warning unit has a built-in three-level early warning threshold library and completes gradient early warning and linkage control by combining the core operating parameters of the equipment. It also integrates structural characteristic parameters such as plate polarity switching, series-parallel mode selection, and automatic water replenishment. The three-level early warning threshold library includes Level 1 (slight deviation), Level 2 (significant deviation), and Level 3 (severe deviation) early warnings. Specifically: The data processing unit filters and removes outliers from the raw data of the signal acquisition module, performs fusion analysis on multiple parameters, and stores the processed effective data. It supports historical data tracing and operating condition trend analysis. The processed signal is transmitted to the main control module through a dedicated transmission unit to ensure the accuracy and timeliness of data transmission. The graded early warning unit sets multiple levels of early warning based on the degree to which parameters deviate from the preset threshold. Different early warning levels correspond to different audible and visual alarm signals. The main control module matches the corresponding control response logic for different early warning levels to achieve graded protection of the equipment. In terms of equipment structure, the series and parallel connection mode of the treatment branches is selected according to the hardness of the circulating water. The anode and cathode plates in reactor 5 can realize intelligent polarity switching to help the scale on the plate surface to fall off. The cleaning tank 7 is equipped with 9 water supply pipes to realize automatic water replenishment according to the liquid level. The electromagnetic coil 10 activates the water flow by high-frequency oscillation. The metal electrode assembly can be made of aluminum, zinc, or copper, either alone or in combination. The electrode surface of the electrocatalytic electrode assembly is coated with a special catalyst, and the catalytic reaction is enhanced by an external electric field.

[0029] Specifically, If, during equipment operation, the parameters acquired by the signal acquisition module show a significant deviation or even fail as a serious warning signal, the main control module will immediately activate the corresponding emergency processing logic.

[0030] If the flow parameters of a certain processing branch are abnormal, the main control module will adjust the valve opening of the corresponding branch and simultaneously adjust the operating parameters of the relevant functional components to achieve rapid flow recovery. If the pressure of filter 6 or bag filter 8 exceeds the limit, the main control module will activate the fault isolation mechanism to partially shut down the faulty branch, while ensuring that the other branch maintains low-load operation to meet the basic water supply needs of the circulating water system. If the core parameters fail or exceed the standard, the main control module will initiate an emergency shutdown operation for the whole machine or a part of it, close the main water inlet valve or related functional components to prevent equipment damage and water treatment failure, and at the same time trigger multi-level audible and visual alarms and remote push notifications to remind staff to troubleshoot the fault in time.

[0031] Staff can quickly locate the cause of the fault based on the historical data stored in the control system. After the fault is handled, the main control module can automatically restart the equipment and restore normal operation. The entire abnormal operation response process does not require manual parameter adjustment, ensuring the efficiency of equipment fault handling.

[0032] The above description is merely a specific embodiment of this application, enabling those skilled in the art to understand or implement this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features claimed herein.
