Technical Field

[0001] The present invention relates to the technical field of equipment cleaning, and in particular to an equipment cleaning system and a cleaning method thereof. Background Art

[0002] During equipment production and operation and maintenance, ensuring the cleanliness of product cooling lines is crucial for extending product life. This is because, over time, the cooling medium and lines are affected by internal factors such as aging and electrochemical corrosion, as well as external factors such as air dust and biological contamination, which gradually accumulate and severely damage the product's temperature control and sealing capabilities. Contamination in the production process is primarily caused by changes in temperature and water quality during pressure testing. If not cleaned promptly, contamination will also accumulate during transportation. However, traditional equipment cleaning methods require a lot of manpower, have low cleaning efficiency, and produce poor cleaning results. Summary of the Invention

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0021] It should be noted that, in the description of the present invention, the terms "comprises," "includes," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. The terms "first," "second," etc., in the present invention are used to distinguish similar objects, and are not used to describe a particular order or precedence.

[0022] In order to enable those skilled in the art to better understand the solutions of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0023] In conjunction with the specific application environment architecture or specific hardware architecture on which the execution of the equipment cleaning system depends, the specific application environment architecture or specific hardware architecture is described here.

[0024] An embodiment of the present invention provides an equipment cleaning system. Figure 1 A schematic diagram of the structure of the equipment cleaning system provided in an embodiment of the present invention is shown in FIG. Figure 1 As shown, the system includes:

[0025] The upper computer is used to monitor the water quality according to the sensor data in the clean water tank of the pulse cleaning device when cleaning is not in progress; when the water quality exceeds the set qualified range, it sends a first instruction to the control circuit; when the water quality is within the set qualified range, it sends a second instruction, a third instruction and a fourth instruction to the control circuit in sequence according to the pre-generated process digital file;

[0026] The control circuit is configured to, after receiving a first instruction, control the pulse cleaning device to perform a filtering and disinfecting operation; after receiving a second instruction, control the pulse cleaning device to perform a self-test operation; after receiving a third instruction, control the pulse cleaning device to perform an air tightness test on the equipment to be cleaned; after receiving a fourth instruction, control the pulse cleaning device to perform a pulse cleaning operation on the equipment to be cleaned;

[0027] The pulse cleaning device is used to perform filtering and disinfection operations and self-inspection operations on itself under the control of the control circuit. After the self-inspection is completed, the equipment to be cleaned is sequentially subjected to air tightness detection and pulse cleaning operations.

[0028] It should be noted that the pulse cleaning device described above utilizes the characteristics of pulsed water vapor or airflow to clean equipment. The equipment to be cleaned can be any device with at least one cleaning pipe, such as a liquid-cooled server (i.e., a cold plate server). Before cleaning, the host computer can monitor the clean liquid in the clean water tank in real time. If the liquid fails to meet the standards, it undergoes a multi-cycle bacteriostatic, filtration, and ultraviolet disinfection treatment to ensure cleanliness. The host computer can also monitor for liquid level alarms. The clean water tank can be equipped with temperature sensors, pH sensors, total dissolved solids (TDS) sensors, and adenosine triphosphate (ATP) sensors.

[0029] During temperature equilibrium, if sensor data within the clean water tank indicates unqualified water quality—for example, TDS > 9 mg / L, total colony count > 100 CFU / mL, or pH > 7—the host computer sends a first instruction to the control circuit, initiating the addition of an antibacterial agent, filtration, and UV disinfection processes. Simultaneously, the host computer software interface displays the status; air tightness testing and pulse cleaning operations are not possible at this time. If the water quality remains unqualified, the above instructions are repeated until it passes. If the number of repetitions exceeds a preset value, an alarm is issued and the system shuts down. When the water quality passes (and there are no liquid level alarms), the host computer sequentially issues three process flow instructions: a self-test (which may include an air tightness test and pulse cleaning of the device itself), an air tightness test of the equipment to be cleaned, and pulse cleaning, according to the process sequence specified in the digital process file. The system then determines whether these three process flow instructions are qualified.

[0030] In the equipment cleaning system provided by the embodiment of the present invention, the water quality in the clean water tank of the pulse cleaning device is monitored by the upper computer before cleaning; when the water quality exceeds the set qualified range, the pulse cleaning device is controlled by the control circuit to perform filtering and disinfection operations, which can eliminate the interference of the device's own water quality and ensure that the water quality is in good condition before cleaning, laying a solid foundation for the effectiveness of subsequent cleaning; and when the water quality is within the set qualified range, the corresponding instructions are sent to the control circuit in an orderly manner according to the pre-generated process digital file, and the control circuit controls the pulse cleaning device to complete the self-test operation, the air tightness test of the equipment to be cleaned, and the pulse cleaning operation of the equipment to be cleaned in sequence according to the received corresponding instructions. This not only eliminates the risk of leakage of the device itself and the pipeline of the equipment to be cleaned, but also enhances the safety and reliability of the cleaning operation, comprehensively improves the cleaning quality and cleaning efficiency of the equipment, and realizes precise management and efficient guarantee of the entire process from water quality control to cleaning. The above system can ensure the standardization and accuracy of equipment cleaning, the rigorous process and the influence of unplugging the pipe midway, and effectively prevent liquid leakage caused by the accumulation of pollution in the equipment during production testing and daily use.

[0031] Furthermore, in a specific implementation, in the above-mentioned equipment cleaning system provided in an embodiment of the present invention, the equipment to be cleaned may include at least one pipe for heat exchange in and out; the pulse cleaning device may include a detection pipeline component; when the pulse cleaning device performs a self-inspection operation, the water inlet and water outlet of the detection pipeline component are in a docking state; the self-inspection operation includes the pulse cleaning device performing an air tightness detection and a pulse cleaning operation on itself; when the pulse cleaning device performs an air tightness detection and a pulse cleaning operation on the equipment to be cleaned, the water inlet of the detection pipeline component is connected to the water outlet of the pipeline; the water outlet of the detection pipeline component is connected to the water inlet of the pipeline.

[0032] During implementation, before cleaning the equipment to be cleaned, the water inlet and water outlet of the detection pipeline component in the pulse cleaning device can be connected first to perform its own air tightness detection and pulse cleaning operation. After the pulse cleaning device is cleaned, the water inlet and water outlet of the detection pipeline component are disconnected and connected to the water outlet and water inlet of the equipment to be cleaned respectively. It should be noted that the detection pipeline component can include multiple pairs of detection pipelines, each pair of detection pipelines has a water inlet and a water outlet, the water inlet of each pair of detection pipelines corresponds one-to-one with the water outlet of the pipeline of the equipment to be cleaned, and the water outlet of each pair of detection pipelines corresponds one-to-one with the water inlet of the pipeline of the equipment to be cleaned.

[0033] Furthermore, in specific implementation, in the above-mentioned equipment cleaning system provided in the embodiment of the present invention, the host computer can also be used to transmit the identity of the equipment to be cleaned, the coding of the pulse cleaning device and the coding of the detection pipeline components to the production management system when the water quality is within the set qualified range, so that the production management system generates a process digital file and feeds it back to the host computer; the process digital file includes process parameters and process records related to self-test operations, air tightness detection and pulse cleaning operations.

[0034] In implementation, assuming the water quality is acceptable (and there are no liquid level alarms), before cleaning begins, the host computer can interact with the production management system. This production management system can be a Manufacturing Execution System (MES). The host computer allows the production management system to scan the serial number (SN) of the equipment to be cleaned and the barcodes of the pulse cleaning device and the test pipeline components used to bind them, generating a digital process profile. The host computer retrieves the corresponding process parameters from the production management system. The process parameters in the digital process profile can include process parameters for device self-tests, air tightness testing, and pulse cleaning operations on the equipment to be cleaned. These parameters are matched to the equipment's ID, meaning different parameters apply to different equipment. These parameters are retrieved from the production management system by scanning the barcode. Based on the sequential execution of the process flow instructions, the host computer records the corresponding process parameters and displays them on the software interface. The inflation pressure, cleaning pressure, and pulse frequency values ​​are converted into control parameters and transmitted to the control circuit. That is, the second instruction carries the control parameters obtained by converting the numerical values ​​of inflation pressure, cleaning pressure, and pulse frequency corresponding to the self-test operation; the third instruction carries the control parameters obtained by converting the inflation pressure corresponding to the air tightness test of the equipment to be cleaned; the fourth instruction carries the control parameters obtained by converting the numerical values ​​of inflation pressure, cleaning pressure, and pulse frequency corresponding to the cleaning operation of the equipment to be cleaned.

[0035] Figure 2 This is a schematic diagram of the architecture of the equipment cleaning system provided in the embodiment of the present invention. Figure 2 As shown in the figure, the equipment cleaning system includes a host computer, control circuitry, pulse cleaning devices, and a production management system. The host computer can be divided into a computer unit, host computer software, and a data acquisition module. The control circuit primarily includes a controller, safety switches, relays, frequency converters, and digital-to-analog converters. The controller can be a programmable logic controller (PLC). The pulse cleaning device includes water treatment components, aeration components, pulse cleaning components, and detection pipeline components. The computer unit and the data acquisition module can communicate via the Modbus / RS485 (Modicon bus / RS485 communication interface) protocol, processing data from various sensors and pressure gauges in the pulse cleaning device and transmitting it to the host computer software deployed in the computer unit. The computer unit and the production management system can establish TCP / IP (Transmission Control Protocol / Internet Protocol) communication with the PLC. The host computer software communicates with the corresponding service of the production management system via a Web Application Programming Interface (WebAPI) interface. The host computer software is divided into a water treatment module, an aeration test module, and a pulse cleaning module based on the device's functions. The data from the data acquisition module is summarized accordingly. For any steps that fail to meet the requirements, the host computer software displays an alarm. For example, if an alarm indicates that the water quality has failed multiple treatments, the sampling valve is operated or the data is checked. If necessary, the water source, filter element, or antibacterial agent is replaced. If an alarm indicates that the aeration or cleaning process has failed, the corresponding device pipeline or equipment to be cleaned is repaired and inspected. The data acquisition module converts the sensor data format or communication protocol of each component in the pulse cleaning device. This embodiment prefers sensors and pressure gauges that output digital signals. If non-digital signals are output, the data acquisition module can convert analog signals into digital signals. The host computer sends instructions to the PLC to control the switching and adjustment of various components of the pulse cleaning device, such as the air source, water pump, and solenoid valve. Relays are used to control the preset time, convert the angle data of the solenoid proportional valve, and a frequency converter is used to adjust the water pump pressure. This allows the host computer to control the control circuit, further enabling control of the pulse cleaning device.

[0036] Furthermore, in a specific implementation, in the above-mentioned equipment cleaning system provided in an embodiment of the present invention, the pulse cleaning device may include, in addition to the detection pipeline component, a water treatment component, an aeration component, and a pulse cleaning component. The pulse cleaning component may draw water from the clean water tank in the water treatment component to the water-gas mixing tank; the aeration component is divided into two output ports by an electromagnetic three-way valve, one of which is directed to the water-gas mixing tank in the pulse cleaning component; the other output port is directed to the next electromagnetic three-way valve, where control gas or pulse water gas enters the detection pipeline component; the input port of the detection pipeline component is connected to the output ports of the aeration component and the pulse cleaning component respectively through the electromagnetic three-way valve.

[0037] During implementation, the input port of the detection pipeline component can be connected to the inflation component and the pulse cleaning component in sequence through the electromagnetic three-way valve, pressure gauge, safety pressure relief valve, and electromagnetic straight-through valve, and can be divided into multiple pairs of detection pipeline channels through the three-way valve at the rear end.

[0038] In specific implementation, in the above-mentioned equipment cleaning system provided in the embodiment of the present invention, the water treatment components may include a clean water tank, a pure water inlet pipeline, a booster pump, a one-way valve, a safety pressure relief valve, a flow meter, a safety solenoid valve, an electromagnetic straight-through valve, a sampling valve, a constant pressure valve, a pipeline-type filter row, an activated carbon filter device, an ultraviolet disinfection device, a transfer water tank, a waste water tank, etc., and are connected in order according to safety regulations and liquid movement rules. Among them, the sampling valve is used for water quality sampling at each stage to facilitate daily inspections. The clean water tank, the transfer water tank, and the waste water tank all have liquid level detection and automatic exhaust functions; a sensor group for monitoring water quality is deployed in the clean water tank to monitor water quality in real time.

[0039] The inflation generating components may include an air source, a manual sliding valve, an air source processor, an air source management unit, an electromagnetic proportional valve, a dryer, a one-way valve, etc., and are connected in the first place according to the set input and output sequence.

[0040] The pulse cleaning generating component may include a water-gas mixing tank, a pressure sensor, a pressure gauge, a high-pressure pump, an electromagnetic straight-through valve, a boost pump, an oscillator, a pulse generator, an electromagnetic proportional valve, etc.; wherein, the high-pressure pump is connected to the electromagnetic straight-through valve, and draws water from the clean water tank to the water-gas mixing tank; when the electromagnetic straight-through valve is opened to draw air from the inflation generating component, it passes through the boost pump, oscillator, pulse generator and electromagnetic proportional valve in sequence, and finally enters the detection pipeline component through the one-way valve and the electromagnetic three-way valve.

[0041] In implementation, Figure 3 This is a schematic diagram of the structure of the water treatment component, the aeration generating component, and the pulse cleaning generating component in the pulse cleaning device provided by the embodiment of the present invention. Figure 3As shown, the water treatment components may include: expandable multi-channel pipeline 1, solenoid valve 2, pure water inlet pipeline 3, check valve 4, booster pump 5, flow meter (FI) 6, safety pressure relief valve 7, pressure gauge 8, safety solenoid valve 9, manual filling port 10, liquid level sensor 11, clean water tank 12, temperature sensor 13, pH sensor 14, TDS sensor 15, ATP sensor 16, solenoid through valve 17, constant pressure pump 18, sampling valve 19, automatic exhaust valve 20, transfer water tank 21, safety pressure relief valve 22, high-pressure pump 23, ultraviolet disinfection device 24, activated carbon filter 25, pipeline filter 26, and wastewater tank 27. A refers to high-quality water. B refers to wastewater.

[0042] The pulse cleaning generating components may include: a water-gas mixing tank 28, a one-way valve 4, a flow meter 6, a safety pressure relief valve 7, a pressure gauge 8, a high-pressure pump 23, a pressure sensor (PS) 29, an electromagnetic through valve 17, a booster pump 5, an electromagnetic proportional valve 30, a muffler 31, an oscillator 32, and a pulse generator 33.

[0043] The inflation generating component may include: an air source 34, a manual sliding valve 35, an air source processor 36, an air source management unit 37, an electromagnetic proportional valve 30, an electromagnetic three-way valve 38, a one-way valve 4, a muffler 31, a dryer 39, and a pressure gauge 8. The inflation generating component is connected to the detection pipeline component through a common return air channel 40.

[0044] Furthermore, in a specific implementation, in the above-mentioned equipment cleaning system provided in an embodiment of the present invention, the detection pipeline component may include a shared water and gas inlet channel, a return air channel, and a drain air channel. The entire detection pipeline component is connected to the output ports of the inflation generating component and the pulse cleaning generating component, respectively, via an electromagnetic three-way valve. The detection pipeline component may include a shared water and gas inlet channel, a return air channel, and a drain air channel. The three-way valve can be used to divide the shared water and gas inlet channel into multiple channels, for example, three channels. The shared water and gas inlet channel is sequentially connected to an electromagnetic proportional valve, an electromagnetic straight-through valve, two sets of temperature sensors, an ultrasonic sensor, a flow sensor, a pressure sensor, and a one-way valve. The shared water and gas inlet channel is connected to the return air channel and the drain air channel via an electromagnetic three-way valve. The return air channel and drain air channel of each detection pipeline component channel, respectively, are connected to the common return air channel and common drain air channel, respectively, via a one-way valve and a three-way valve. The return air channel is sequentially connected to the electromagnetic straight-through valve, a one-way valve, a pressure reducing valve, a humidity sensor, and a gas concentration sensor. The drain air channel is sequentially connected to the electromagnetic straight-through valve, a one-way valve, a pressure reducing valve, and a sensor group. Through channel design and component configuration, such detection pipeline components can achieve multifunctional integration and precise detection. The shared water and gas inlet channel is connected in series with multiple sensors, such as temperature, ultrasonic, flow, and pressure sensors, which can monitor key parameters such as fluid temperature, flow, and pressure in real time, providing accurate data support for the cleaning and detection process. The return air channel is equipped with humidity and gas concentration sensors, which can effectively detect gas humidity and composition to ensure gas quality. The sensor group in the drainage channel can perform comprehensive detection of the discharged water and gas mixture. At the same time, the setting of the electromagnetic three-way valve and the one-way valve not only realizes flexible switching and fluid flow control between channels, avoiding the interference of gas-water backflow, but also optimizes the pipeline layout and improves detection efficiency through the design of common return air and common drainage channels. The coordination of the electromagnetic proportional valve, electromagnetic straight-through valve, and pressure reducing valve can accurately adjust the fluid pressure and flow, ensuring the stable and efficient operation of the entire detection and cleaning process, enhancing the reliability and safety of the system, and is suitable for equipment detection and cleaning operations under various complex working conditions.

[0045] It's important to note that pulse cleaning systems can be expanded to three or more channels, allowing simultaneous cleaning of multiple groups of equipment. The air source can be introduced from a pipeline or by replacing the air tank. This can be cut off with a manual valve; otherwise, replacement is impossible. Water can be introduced from a pipeline or manually injected. During manual injection, the safety valve activates, shutting off other pressure devices and fluid flow.

[0046] Figure 4 This is a schematic diagram of the structure of the detection pipeline components in the pulse cleaning device provided by the embodiment of the present invention. Figure 4As shown, the detection pipeline components may include: a common return air channel 40, a return air channel 41, a drainage air channel 42, a common water vapor inlet channel 43, a common drainage air channel 44, a quick-connect self-sealing plug 45, an ultrasonic sensor 46, a pressure reducing valve 47, a gas concentration sensor 48, a humidity sensor 49, a one-way valve 4, a flow meter 6, a dryer 39, a temperature sensor 13, a pressure sensor 29, a pH sensor 14, a TDS sensor 15, an ATP sensor 16, a muffler 31, an electromagnetic three-way valve 38, an electromagnetic straight-through valve 17, and an electromagnetic proportional valve 30. C represents the first equipment product to be cleaned, and D represents the nth equipment product to be cleaned (n is greater than 1).

[0047] It should be noted that the host computer can use flow sensors, pressure sensors, and gas concentration sensors to determine whether the pipeline meets cleanliness and safety requirements. The host computer can also determine whether there is a leak in the equipment to be cleaned by the difference between the pressure sensor and the flow sensor.

[0048] Since the pulse cleaning device provided by the embodiment of the present invention has multiple one-way valves, safety pressure relief valves, pressure gauges, booster pumps, and flow meters, the present invention Figure 3 and Figure 4 The same components are uniformly labeled, such as the one-way valve 4, the safety pressure relief valve 7, the pressure gauge 8, the high-pressure pump 23, the electromagnetic through valve 17, the booster pump 5, the electromagnetic proportional valve 30, the electromagnetic three-way valve 37, the muffler 31, the constant pressure pump 18, etc.

[0049] Furthermore, in a specific implementation, in the above-mentioned equipment cleaning system provided by an embodiment of the present invention, the control circuit can be used to control the electromagnetic three-way valve to open the detection gas circuit of the inflation generating component when controlling the pulse cleaning device to perform air tightness testing on itself or the equipment to be cleaned, and to control the pressure regulating valve to inflate the detection pipeline component. When the sensor data of the detection pipeline component reaches a set threshold, the gas output is stopped. After a preset static time, the pulse cleaning device's own air tightness is determined to be within a preset parameter range based on the pressure sensor value and gas concentration change after the temperature sensor is balanced. If not, an alarm is issued. The control circuit can also be used to control the electromagnetic three-way valve to call the water treatment component, the inflation generating component, and the pulse cleaning generating component respectively when controlling the pulse cleaning device to perform pulse cleaning operations on itself or the equipment to be cleaned, so as to open the pulse cleaning pipeline and transmit pulse water gas to the detection pipeline component.

[0050] In practice, the control circuit controls the solenoid three-way valves according to process flow instructions, respectively activating the pulse cleaning device's aeration generator, pulse cleaning generator, and drainage channels for the test pipeline. The solenoid proportional valves are adjusted and pressure relief is performed based on relevant pressure data to ensure device stability and safety. When the host computer executes the device's self-test command, it aligns the test pipeline's water inlet and outlet and confirms this on the system interface. After confirmation, the control circuit controls the pulse cleaning device, activating the aeration generator and drainage channels. During the self-test airtightness test, the control circuit opens the test air circuit to detect humidity and eliminate water before controlling the pressure regulating valve to purify the pipeline of the equipment being cleaned. The host computer checks the values ​​of the test pipeline's pressure sensor, humidity sensor, ultrasonic sensor, and gas concentration sensor to determine if they meet the requirements. If not, the pulse cleaning device is controlled to release pressure based on the pressure data and determines if the pressure relief is complete. If the pressure relief is complete, the control circuit controls the pulse cleaning device to inflate until the ultrasonic sensor and humidity sensor of the pipeline components are judged to be qualified. The electromagnetic proportional valve is then adjusted according to the corresponding inflation pressure, and the pulse cleaning device is left to stand for a preset time (i.e., the first preset time value of the self-test). After the preset standing time, the pressure sensor value and gas concentration change after the temperature sensor is balanced are detected to determine whether the air tightness is qualified. That is, the host computer can read the allowable pressure difference and allowable flow difference and compare them with the corresponding process requirements, such as pressure change ≤1‰, flow change ≤1.5‰. If the requirements are met, the data will be uploaded to the production management system and passed to the station. If not, an alarm signal will be sent to repair the pulse cleaning device.

[0051] After the pulse cleaning device has passed the air tightness test, the pipeline components are not disconnected. After the system interface is confirmed, the upper computer can control the electromagnetic three-way valve to call the pulse cleaning generating components and the drainage gas channel. After the pressure is sufficient, the electromagnetic straight-through valve near the water-gas mixing tank is opened to generate pulses. After the pulse pressure is qualified, the electromagnetic straight-through valve of the water-gas entry channel is opened to perform pulse cleaning operations. After pulse cleaning, relevant pressure data, such as pressure gauge and pressure sensor data, are read to control the electrical proportional valve and pressure relief valve to ensure pressure stability and safety.

[0052] It should be noted that the air tightness test and pulse cleaning operation for the equipment to be cleaned are consistent with the process of the pulse cleaning device's self-test air tightness test and pulse cleaning operation. The difference is that the judgment of whether it passes is based on the corresponding process requirements, such as the pressure required by the equipment to be cleaned, the pressure change and flow change values ​​required by the equipment to be cleaned. The equipment to be cleaned generally requires a pressure change of ≤3‰ and a flow change of ≤3‰. After uploading the process digital file for storage and verification, the equipment to be cleaned can pass the station. In addition, after connecting a pair of test pipelines, it is necessary to scan the code again for verification to prevent incorrect use.

[0053] In actual application, the inflation pressure and cleaning pressure are monitored in real time by the host computer and regulated according to the pressure required by the product. Usually the product pressure does not exceed 3MPa. If the product allows a pressure of 2.0-2.5MPa, the host computer will regulate the safety relief valve according to the pressure gauge to release the pressure when the range is greater than 2.4MPa, and adjust the electromagnetic proportional valve according to the pressure sensor to stabilize the pressure at 2.3 0.007Mpa (3 thousandths).

[0054] Furthermore, in a specific implementation, in the above-mentioned equipment cleaning system provided in an embodiment of the present invention, the control circuit can also be used to start the corresponding high-pressure water pump and electromagnetic straight-through valve after receiving the first instruction, if the flow sensors around the pipeline-type filter row of the water treatment component and the transfer water tank do not detect flow fluctuations, so as to drain the liquid in the transfer water tank back to the clean water tank.

[0055] During implementation, after the flow sensors near the pipeline filter row and transfer water tank of the water treatment component detect no flow fluctuations, the control circuit starts the corresponding high-pressure water pump and electromagnetic straight-through valve to drain the liquid in the transfer water tank back to the clean water tank, and the drainage is completed and then tested.

[0056] Furthermore, in a specific implementation, in the above-mentioned equipment cleaning system provided in an embodiment of the present invention, the host computer is also used to read the temperature value and sensor value from the start to the completion of pulse cleaning, take the sensor data within the preset cleaning duration to perform temperature factor correction, and judge whether the corrected sensor data meets the water quality requirements. If so, a stop command is issued to the control circuit; if not, repeated pulse cleaning operations are performed. If the pulse cleaning operation exceeds the preset number of times, a stop command is issued to the control circuit and an alarm prompt is issued.

[0057] During implementation, the host computer reads the temperature, TDS, ATP, and pH sensor values ​​from the start to the end of the pulse cleaning process. It then uses the sensor data from the last 10% of the preset cleaning duration (the second preset self-test time) to correct for temperature. If the water quality requirements are met, such as TDS < 9 mg / L, total colony count < 100 CFU / mL, and pH < 7, the pulse cleaning is deemed qualified and the process digital file is uploaded for storage. If not, repeated pulse cleaning is performed. If the cleaning frequency exceeds the preset number, the device shuts down and issues an alarm.

[0058] The following is an example of the operation process of the above equipment cleaning system, which may include:

[0059] When the pulse cleaning device performs its own air-tightness test, the piping is connected, and the host computer interface confirms the start of the device's self-test for air-tightness. Before and during inflation, the host computer uses the pressure sensor and pressure gauge to determine whether pressure relief is required. Based on process parameters such as the device's inflation pressure, the host computer transmits these parameters to the control circuit via a digital-to-analog converter. The host computer checks whether the solenoid straight-through valves in other pathways unrelated to air-tightness are closed and whether the solenoid three-way valves are correctly oriented, adjusting them accordingly. When the host computer activates the inflation generator, it opens the corresponding air supply management unit, allowing the gas to flow sequentially through the manual valve, the air source processor, and the air supply management unit. When the host computer activates the inflation generator, it opens the corresponding solenoid three-way valve direction and the solenoid straight-through valve before the branch channel. After the gas passes through the manual valve, the air source processor, and the air supply management unit, it passes through the solenoid proportional valve, the dryer, the pressure gauge, and the solenoid three-way valve to the inspection management unit. When the inflation component is activated, the electromagnetic straight-through valve and the corresponding electromagnetic three-way valve in the corresponding detection pipeline component channel are opened, allowing the gas to pass through the temperature sensor, ultrasonic sensor, flow sensor, and pressure sensor, and the channel pressure is maintained by the electromagnetic proportional valve. After passing through the pressure reducing valve, dryer, humidity sensor, gas concentration sensor, and one-way valve of the return air channel, the gas is returned to the common return air channel through the electromagnetic three-way valve. Then, inflation is continued until the temperature is calibrated. When the humidity sensor value is ≤3RH, inflation is carried out for 30 seconds. After temperature calibration, the ultrasonic sensor value is ≤1RH. Continue inflation and adjust the electromagnetic proportional valve opening until the pressure sensor reaches the preset pressure value. After standing for 5 minutes, the pressure sensor pressure change is ≤1‰, and the flow sensor change is ≤1.5‰, the air tightness test is considered qualified.

[0060] Testing the equipment for air tightness is the same as above, except that the equipment's piping must first be connected to the pulse cleaning device's detection line. In subsequent steps, air is continuously inflated until the temperature is corrected. When the humidity sensor reading is ≤3.5RH, air is inflated for 30 seconds. After temperature correction, the ultrasonic sensor reading is ≤1.5RH. Continue inflating and adjust the solenoid proportional valve opening until the pressure sensor reaches the preset pressure. After 5 minutes of standing, the pressure sensor pressure changes by ≤3‰, and the flow sensor changes by ≤3‰, indicating a passing air tightness test.

[0061] While the pulse cleaning device performs its own pulse cleaning operation, the pipelines remain connected. The host computer interface confirms the start of the device's self-test pulse cleaning. The host computer determines whether pressure relief is required before and during cleaning based on the pressure sensor and pressure gauge. Based on process parameters such as the device's cleaning pressure, the host computer transmits these parameters to the control circuit via a digital-to-analog converter. The host computer checks whether the solenoid through-valve in other pathways unrelated to the pulse cleaning process is closed and whether the solenoid three-way valve is correctly positioned, adjusting these parameters accordingly. When the host computer activates the pulse cleaning generator, it simultaneously opens the solenoid valves and high-pressure pumps connecting the clean water tank and the air source to the water-gas mixing tank. When the pressure in the water-gas mixing tank reaches a certain level, the solenoid through-valve and booster pump after the water-gas mixing tank are opened. The booster pump is depressurized if it exceeds the safe pressure. The water-gas mixture then passes through an oscillator and then a pulse generator. After maintaining pressure throughout the test pipeline components through a solenoid proportional valve, the mixture enters the test pipeline components through a solenoid three-way valve. When pulse cleaning is initiated, the solenoid through-valve and three-way valves in the corresponding detection pipeline components are opened, allowing the high-pressure water-gas mixture to pass through the temperature sensor, ultrasonic sensor, flow sensor, and pressure sensor. The pressure in this channel is maintained by a solenoid proportional valve. After passing through the pressure reducing valve, temperature sensor, pH sensor, TDS sensor, ATP sensor, and one-way valve in the drainage channel, the gas enters the common drainage channel through the solenoid three-way valve. Cleaning continues for 5 minutes, and data from the temperature, pH, TDS, and ATP sensors are captured for the last 10% of the time. The pulse cleaning is considered qualified if the temperature-corrected TDS is less than 9 mg / L, the total bacterial count is less than 100 CFU / mL, and the pH is less than 7.

[0062] The pulse cleaning operation for the equipment to be cleaned is consistent with the above process, except that the pipeline of the equipment to be cleaned needs to be connected to the detection pipeline of the pulse cleaning device first; the process parameters can be adjusted according to actual conditions.

[0063] It should be noted that when the pulse cleaning device does not initiate inflation, pulse cleaning, or other instructions, in non-automatic water injection mode, the water inlet is sealed and the flow meter does not change. The host computer can send instructions to the PLC to close the safety solenoid valve, preventing water and gas from entering. If the clean water tank liquid level is detected to be insufficient (the second liquid level warning value), the host computer will prompt you to add water. If the clean water tank liquid level is detected to be insufficient (the third liquid level warning value), an alarm will be triggered and inflation and pulse cleaning instructions will not be possible. When the device does not initiate inflation, pulse cleaning, or other instructions, in automatic water injection mode, if the clean water tank liquid level is detected to be insufficient (the second liquid level warning value), the solenoid valve, booster pump, and safety solenoid valve will be opened to start pure water delivery. After adding water to a certain level (the first liquid level warning value), the solenoid valve, booster pump, and safety solenoid valve will be closed.

[0064] After the water quality in the clean water tank is monitored for a set period of time (such as 5 minutes), if the temperature-corrected TDS is less than 9 mg / L, the total colony count is less than 100 CFU / mL, and the pH is less than 7, the water quality is judged to be qualified. When pulse cleaning occurs, the electromagnetic straight-through valve and the high-pressure pump can be opened to transport the water to the water-gas mixing tank.

[0065] If any of the above three parameters fail, the electromagnetic direct-flow valve, high-pressure pump, and electromagnetic direct-flow valve are opened, and water from the clean water tank is diverted through a pipeline-type filter, activated carbon filtration, and ultraviolet disinfection, sequentially into the transfer tank. When the liquid level sensor in the transfer tank shows no significant increase (k < 10 ml / s) and the liquid level sensor in the clean water tank shows no significant decrease (k < 10 ml / s), the flow meter on the clean water tank-to-transfer tank diversion route (the flow meter reading is close to 0 or < 5 ml / s) is then checked. The electromagnetic direct-flow valve and high-pressure pump on the diversion route from the clean water tank to the transfer tank are closed, and the electromagnetic direct-flow valve and constant pressure pump from the transfer tank to the clean water tank are opened to divert the purified water into the clean water tank. Simultaneously, during diversion, the pressure gauge near the high-pressure pump determines whether to activate the safety relief valve to release pressure, and the high-pressure pump speed is adjusted via the frequency converter.

[0066] If the liquid level in the transfer water tank does not decrease significantly (k < 10 ml / s) and the liquid level in the clean water tank does not increase significantly (k < 10 ml / s), the two flow count values ​​from the transfer water tank to the clean water tank are close to 0 or < 5 ml / s, stop the electromagnetic through valve and constant pressure pump.

[0067] After monitoring the water quality in the clean water tank for 5 minutes, if the temperature-corrected TDS is less than 9 mg / L, the total colony count is less than 100 CFU / mL, and the pH is less than 7, the water quality is considered qualified. If it fails, the above process is repeated. If the number of counts exceeds a preset 5 times (adjustable, such as ≤5), the device will shut down and alarm, and samples will be taken for inspection and analysis of the relevant parameters.
