[0002] In the equipment production and operation and maintenance processes, ensuring the cleanliness of the product cooling pipeline is of great help in improving the service life of the product. This is because over time, its cooling medium and pipeline will be gradually affected by internal factors such as aging and electrochemical corrosion, as well as external factors such as air dust and biological contamination, which will gradually accumulate and cause serious damage to the temperature control and sealing capabilities of the product. In the production process, it is mainly due to possible contamination caused by changes in temperature, water quality, etc. during the pressure test. If not cleaned in time, the contamination will also gradually accumulate during transportation. However, traditional equipment cleaning methods require a large amount of manpower, with low cleaning efficiency and poor cleaning effects. Summary of the Invention

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

[0011] It should be noted that in the description of the present invention, the terms "include", "comprise" or any other variant thereof are intended to cover a non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device. The terms "first", "second", etc. in the present invention are used to distinguish similar objects, rather than to describe a specific order or sequence.

[0012] In order to enable those skilled in the art of the present technology to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0013] Combined 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 will be described herein.

[0014] An embodiment of the present invention provides an equipment cleaning system. Figure 1 Schematic structural diagram of the equipment cleaning system provided by an embodiment of the present invention, as Figure 1 shown, the system includes: The host computer is used to monitor the water quality according to the sensor data in the clean water tank of the pulse cleaning device when the 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 sequentially sends a second instruction, a third instruction, and a fourth instruction to the control circuit according to the pre-generated process digital file; The control circuit is used to control the pulse cleaning device to perform filtration and disinfection operations after receiving the first instruction; to control the pulse cleaning device to perform self-check operations after receiving the second instruction; to control the pulse cleaning device to perform airtightness detection on the device to be cleaned after receiving the third instruction; to control the pulse cleaning device to perform pulse cleaning operations on the device to be cleaned after receiving the fourth instruction; The pulse cleaning device is used to perform filtration and disinfection operations and self-check operations on itself under the control of the control circuit, and sequentially perform airtightness detection and pulse cleaning operations on the device to be cleaned after the self-check is completed.

[0015] It should be noted that the above pulse cleaning device is a device that uses the characteristics of pulsed water vapor or air flow to clean the equipment. The above device to be cleaned can be any equipment with at least one cleaning pipeline, such as a liquid-cooled server (i.e., a cold plate server). Before cleaning, the host computer can monitor the cleaning liquid in the clean water tank in real time. If the monitoring is unqualified, it will perform antibacterial, filtration, and ultraviolet disinfection processes that can be cycled multiple times to ensure its cleanliness. In addition, the host computer can also monitor whether there is a liquid level alarm. Temperature sensors, pH (Potential of Hydrogen) sensors, TDS (Total Dissolved Solids) sensors, ATP (Adenosine Triphosphate Sensor) sensors, etc. can be set in the clean water tank.

[0016] When the temperature is balanced, if the sensor data in the clean water tank, such as TDS > 9mg / L, total colony count > 100CFU / mL, pH > 7, it is judged that the water quality is unqualified. The host computer can send a first instruction to the control circuit, thereby starting the processes of adding antibacterial agent, filtration, and ultraviolet disinfection. At the same time, the status is displayed on the host computer software interface, and at this time, airtightness detection and pulse cleaning operations cannot be performed. If the water quality is still unqualified, repeat the above instructions until it is qualified. If the number of repetitions exceeds the preset value, an alarm and shutdown will be performed. When the water quality is qualified (and there is no liquid level alarm), the host computer can sequentially issue three process instructions of device self-check (which can include airtightness detection and pulse cleaning operations of the device itself), airtightness detection of the device to be cleaned, and pulse cleaning according to the process sequence of the process digital file, and judge whether the three process instructions are qualified.

[0017] In the above-mentioned equipment cleaning system provided by the embodiments of the present invention, before cleaning, the quality of the water in the clean water tank of the pulse cleaning device is monitored by the host computer; when the water quality exceeds the set qualified range, the control circuit is used to control the pulse cleaning device to perform filtration and disinfection operations, so as to eliminate the interference of the water quality of the device itself and ensure that the water quality before cleaning is in an excellent state, laying a solid foundation for the subsequent cleaning effectiveness; when the water quality is within the set qualified range, 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-check operation, the airtightness detection 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 risks of pipeline leakage of the device itself and pipeline leakage of the equipment to be cleaned, but also enhances the safety and reliability of the cleaning operation, comprehensively improves the cleaning quality and efficiency of the equipment, and realizes the precise management and efficient guarantee from water quality control to the entire cleaning process. The above system can ensure the standardization and accuracy of equipment cleaning, with a rigorous process and no impact of unplugging pipes midway, effectively preventing liquid leakage caused by the accumulation of pollution during the production test and daily use of the equipment.

[0018] Further, in specific implementation, in the above-mentioned equipment cleaning system provided by the embodiments of the present invention, the equipment to be cleaned may include at least one pipeline for exchanging heat in and out; the pulse cleaning device may include a detection pipeline component; when the pulse cleaning device performs a self-check operation, the water inlet and outlet of the detection pipeline component are in a butted state; the self-check operation includes the airtightness detection and pulse cleaning operation of the pulse cleaning device itself; when the pulse cleaning device performs the airtightness detection and 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.

[0019] In implementation, before cleaning the equipment to be cleaned, the water inlet and outlet of the detection pipeline component in the pulse cleaning device can be butted first to perform the airtightness detection and pulse cleaning operation of itself. After the pulse cleaning device finishes cleaning, the water inlet and outlet of the detection pipeline component are disconnected and respectively connected to the water outlet and water inlet of the equipment to be cleaned. It should be noted that the detection pipeline component may 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 to the water outlet of the pipeline of the equipment to be cleaned one by one, and the water outlet of each pair of detection pipelines corresponds to the water inlet of the pipeline of the equipment to be cleaned one by one.

[0020] Further, in specific implementation, in the above device cleaning system provided by the embodiments of the present invention, the host computer can also be used to transmit the identity identifier of the device to be cleaned, the code of the pulse cleaning device, and the code of the detected pipeline component 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-check operation, airtightness detection, and pulse cleaning operation.

[0021] In implementation, on the premise that the water quality is qualified (and there is no liquid level alarm), before cleaning, the host computer can interact with the production management system. Here, the production management system can be a Manufacturing Execution System (MES). The host computer can allow the production management system to scan the identity identifier (Serial Number, SN) of the device to be cleaned, and scan the barcodes of the pulse cleaning device and the detected pipeline components used for binding to generate a process digital file. The host computer obtains the corresponding process parameters from the production management system. The process parameters in the process digital file can include the process parameters of device self-check and the process parameters of airtightness detection and pulse cleaning operation for the device to be cleaned. Here, the relevant parameters are matched with the identity identifier of the device to be cleaned, that is, different devices have different parameters, and they are called from the production management system by scanning the code. According to the process flow instructions executed in sequence, the host computer can record the corresponding process parameters in the right seats and display them on the software interface, convert the inflation pressure, cleaning pressure, and pulse frequency values into control parameters and send them to the control circuit. That is, the second instruction carries the control parameters obtained by converting the inflation pressure, cleaning pressure, and pulse frequency values corresponding to the self-check operation; the third instruction carries the control parameter obtained by converting the inflation pressure corresponding to the airtightness detection of the device to be cleaned; the fourth instruction carries the control parameters obtained by converting the inflation pressure, cleaning pressure, and pulse frequency values corresponding to the cleaning operation of the device to be cleaned.

[0022] Figure 2 It is a schematic architecture diagram corresponding to the device cleaning system provided by the embodiments of the present invention. As Figure 2As shown in the figure, the equipment cleaning system includes a host computer, a control circuit, a pulse cleaning device, and a production management system. The host computer can be divided into a computer device, host computer software, and a data acquisition module. The control circuit mainly includes a controller, a safety switch, a relay, a frequency converter, a digital-to-analog converter, etc. The controller can be a Programmable Logic Controller (PLC). The pulse cleaning device includes a water treatment component, an air inflation generating component, a pulse cleaning generating component, and a detection pipeline component. The computer device and the data acquisition module can communicate through the Modbus / RS485 (Modicon bus / RS485 communication interface) protocol, process various sensor and pressure gauge data of the pulse cleaning device, and transmit it to the host computer software deployed on the computer device. The computer device and the production management system can establish Transmission Control Protocol / Internet Protocol (TCP / IP) protocol communication with the PLC, and the host computer software and the corresponding service of the production management system can establish a Network Application Programming Interface (WebAPI) interface communication. The host computer software is divided into a water treatment module, an air inflation inspection module, and a pulse cleaning module according to the device function, and respectively summarizes the data of the data acquisition module. For the links that fail the judgment, the host computer software performs an alarm display. For example, an alarm for unqualified water quality after multiple treatments, operate the sampling valve or check according to the data, and replace the water source, filter element or add bacteriostatic agent if necessary. Alarms for unqualified air inflation and cleaning, repair and check the corresponding device pipelines or products of the equipment to be cleaned. The data acquisition module converts the sensor data format or communication protocol of each component in the pulse cleaning device. In this embodiment, sensors, pressure gauges, etc. that output digital signals are preferably selected. If a non-digital signal output appears, the data acquisition module can convert the analog signal into a digital signal. The host computer sends instructions to the PLC to control the on / off and adjustment of components such as the air source, water pump, and solenoid valve of each component of the pulse cleaning device. The control of the preset time is achieved through the relay, and the conversion of the electromagnetic proportional valve angle data is adjusted by the frequency converter to adjust the pressure of the water pump. Thus, the control of the control circuit is realized through the host computer, and further the control of the pulse cleaning device is realized.

[0023] Further, in specific implementation, in the above-mentioned equipment cleaning system provided by the embodiments of the present invention, the pulse cleaning device may include, in addition to the detection pipeline component, a water treatment component, an air inflation generating component, and a pulse cleaning generating component. The pulse cleaning generating component can draw water from the clean water tank in the water treatment component to the water-air mixing tank; the air inflation generating component divides two output ports through an electromagnetic three-way valve. One output port leads to the water-air mixing tank in the pulse cleaning generating component; the other output port leads to the next electromagnetic three-way valve, where air or pulsed water-air is controlled to enter the detection pipeline component; the input port of the detection pipeline component is connected to the output ports of the air inflation generating component and the pulse cleaning generating component respectively through an electromagnetic three-way valve.

[0024] In implementation, the input port of the detection pipeline component can be connected to the air inflation generating component and the pulse cleaning generating component in sequence through an electromagnetic three-way valve, a pressure gauge, a safety relief valve, and an electromagnetic straight-through valve, and can be divided into multiple pairs of detection pipeline channels through a three-way valve at the rear end.

[0025] In specific implementation, in the above-mentioned equipment cleaning system provided by the embodiments of the present invention, the water treatment component may include a clean water tank, a pure water inlet pipeline, a booster pump, a check valve, a safety 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 drain, an activated carbon filtration device, an ultraviolet disinfection device, a transfer water tank, a waste water tank, etc., and are connected in an orderly manner according to safety specifications and liquid flow rules. Among them, the sampling valve is used for water quality sampling at each stage to facilitate daily inspection. 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 inside the clean water tank for real-time water quality monitoring.

[0026] The air inflation generating component may include an air source, a hand-operated slide valve, an air source processor, an air source management unit, an electromagnetic proportional valve, a dryer, a check valve, etc., and are connected in sequence according to the set input and output order.

[0027] The pulse cleaning generating component may include a water-air mixing tank, a pressure sensor, a pressure gauge, a high-pressure pump, an electromagnetic straight-through valve, a booster pump, an oscillator, a pulse generator, an electromagnetic proportional valve, etc.; among them, the high-pressure pump is connected to the electromagnetic straight-through valve and draws water from the clean water tank to the water-air mixing tank; when the electromagnetic straight-through valve is opened to draw air from the air inflation generating component, it passes through the booster pump, the oscillator, the pulse generator, and the electromagnetic proportional valve in sequence, and finally enters the detection pipeline component through a check valve and an electromagnetic three-way valve.

[0028] In implementation, Figure 3 It is a schematic structural diagram of the water treatment component, the air inflation generating component, and the pulse cleaning generating component in the pulse cleaning device provided by the embodiments of the present invention. As Figure 3As shown, the water treatment components may include: expandable multi-way pipeline 1, solenoid valve 2, pure water inlet pipeline 3, check valve 4, booster pump 5, flowmeter (FI) 6, safety relief valve 7, pressure gauge 8, safety solenoid valve 9, manual filling port 10, liquid level sensor 11, purified water storage tank 12, temperature sensor 13, PH sensor 14, TDS sensor 15, ATP sensor 16, electromagnetic direct valve 17, constant pressure pump 18, sampling valve 19, automatic exhaust valve 20, transfer water storage tank 21, safety relief valve 22, high-pressure pump 23, ultraviolet disinfection device 24, activated carbon filtration device 25, pipeline type filter row 26, wastewater storage tank 27. A refers to high-quality water. B refers to wastewater.

[0029] The pulse cleaning generating components may include: water-air mixing tank 28, check valve 4, flowmeter 6, safety relief valve 7, pressure gauge 8, high-pressure pump 23, pressure sensor (PS) 29, electromagnetic direct valve 17, booster pump 5, electromagnetic proportional valve 30, muffler 31, oscillator 32, pulse generator 33.

[0030] The gas charging generating components may include: gas source 34, hand slide valve 35, gas source processor 36, gas source management unit 37, electromagnetic proportional valve 30, electromagnetic three-way valve 38, check valve 4, muffler 31, dryer 39, pressure gauge 8. The gas charging generating components are connected to the detection pipeline components through the common gas return channel 40.

[0031] Further, in specific implementation, in the above-mentioned equipment cleaning system provided by the embodiments of the present invention, the detection pipeline component may include a common water and gas inlet channel, a gas return channel, and a drain gas channel. The whole detection pipeline component is connected to the output ports of the inflation generating component and the pulse cleaning generating component respectively through an electromagnetic three-way valve. The detection pipeline component may include a common water and gas inlet channel, a gas return channel, and a drain gas channel, which can be divided into multiple channels through the three-way valve, for example, divided into three channels. The common water and gas inlet channel is sequentially connected to an electromagnetic proportional valve, an electromagnetic direct-through valve, two groups of temperature sensors, ultrasonic sensors, flow sensors, pressure sensors, and a one-way valve. The common water and gas inlet channel is connected to the gas return channel and the drain gas channel through an electromagnetic three-way valve. The gas return channel and the drain gas channel of each detection pipeline component channel enter the common gas return channel and the common drain gas channel respectively through a one-way valve and a three-way valve. The gas return channel is sequentially connected to an electromagnetic direct-through valve, a one-way valve, a pressure reducing valve, a humidity sensor, and a gas concentration sensor. The drain gas channel is sequentially connected to an electromagnetic direct-through valve, a one-way valve, a pressure reducing valve, and a sensor group. Such a detection pipeline component can achieve multi-functional integration and precise detection through channel design and component configuration. The common water and gas inlet channel is connected in series with various sensors, such as temperature, ultrasonic, flow, and pressure sensors, which can monitor key parameters of the fluid such as temperature, flow, and pressure in real time, providing accurate data support for the cleaning and detection process; the gas return channel is equipped with humidity and gas concentration sensors, which can effectively detect gas humidity and composition to ensure gas quality; the sensor group of the drain gas channel can comprehensively detect 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 the flexible switching between channels and the control of fluid flow direction, avoiding the interference of gas and water backflow, but also optimizes the pipeline layout and improves the detection efficiency through the design of the common gas return and common drain gas channels; the cooperation of the electromagnetic proportional valve, the electromagnetic direct-through valve, and the pressure reducing valve can accurately adjust the fluid pressure and flow rate, ensuring the stable and efficient operation of the whole detection and cleaning process, enhancing the reliability and safety of the system, and being applicable to equipment detection and cleaning operations under various complex working conditions.

[0032] It should be noted that the pulse cleaning device can expand three or more channels to clean multiple groups of equipment simultaneously. The gas source can be introduced from the pipeline or the gas storage tank can be replaced. When replacing, it can be cut off through the hand slide valve. It cannot be replaced when not cut off. The water source can be introduced from the pipeline or manually injected. When manually injecting, the safety valve responds to cut off other pressure devices and fluid flow.

[0033] Figure 4 It is a schematic structural diagram of the detection pipeline component in the pulse cleaning device provided by the embodiments of the present invention. As 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 and gas inlet channel 43, a common drainage and 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 check 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 product of the equipment to be cleaned, and D represents the nth product of the equipment to be cleaned (n > 1).

[0034] It should be noted that the upper computer can judge whether the pipeline meets the cleanliness and safety requirements through the flow sensor, pressure sensor, and gas concentration sensor. The upper computer can judge whether there is a leak in the product of the equipment to be cleaned through the difference between the pressure sensor and the flow sensor.

[0035] Since there are multiple check valves, safety relief valves, pressure gauges, booster pumps, and flow meters in the pulse cleaning device provided by the embodiment of the present invention, the Figure 3 and Figure 4 uniformly label the same components, such as check valve 4, safety relief valve 7, pressure gauge 8, high-pressure pump 23, electromagnetic straight-through valve 17, booster pump 5, electromagnetic proportional valve 30, electromagnetic three-way valve 37, muffler 31, constant pressure pump 18, etc.

[0036] Furthermore, in specific implementation, in the above-mentioned equipment cleaning system provided by the embodiment of the present invention, the control circuit can be used to open the detection gas path of the gas charging component by controlling the electromagnetic three-way valve when controlling the pulse cleaning device to perform airtightness detection on itself or the equipment to be cleaned, and to inflate the detection pipeline components by controlling the pressure regulating valve. When the sensor data of the detection pipeline components reaches the set threshold, stop the gas output. After standing for a preset time, judge whether the airtightness of the pulse cleaning device itself is within the preset parameter range according to the pressure sensor value and gas concentration change after the temperature sensor is balanced. If not, give an alarm prompt. The control circuit can also be used to separately call the water treatment component, gas charging component, and pulse cleaning generating component by controlling the electromagnetic three-way valve when controlling the pulse cleaning device to perform pulse cleaning operation on itself or the equipment to be cleaned, so as to open the pulse cleaning pipeline and transmit the pulse water and gas to the detection pipeline components.

[0037] In implementation, the control circuit can control the electromagnetic three-way valve according to the process flow instructions to separately call the inflation generating component, the pulse cleaning generating component, and the drainage and gas channels of the detection pipeline component of the pulse cleaning device, and adjust the angle of the electromagnetic proportional valve and perform pressure relief processing according to relevant pressure data to ensure the stability and safety of the device. When the upper computer executes the device self-check instruction, it docks the water inlet and outlet of the detection pipeline and confirms it on the system interface. After confirmation, the control circuit controls the pulse cleaning device and calls the inflation generating component and the drainage and gas channels. During the self-check airtightness detection, the control circuit opens the detection gas path. After detecting the humidity and performing water elimination treatment, it controls the pressure regulating valve to inflate the pipeline of the product to be cleaned. The upper computer can detect the values of the pressure sensor, humidity sensor, ultrasonic sensor, and gas concentration sensor of the detection pipeline and determine whether they are qualified. If unqualified, it controls the pulse cleaning device to release pressure according to the pressure data and determines whether the pressure relief is completed. If the pressure relief is completed, the control circuit controls the pulse cleaning device to inflate until the ultrasonic sensor and humidity sensor of the detection pipeline component judge it to be qualified, and then adjusts the electromagnetic proportional valve according to the corresponding inflation pressure and sets the pulse cleaning device for a preset time (i.e., the first preset time value of the self-check). After the preset time, it detects the pressure sensor value and gas concentration change after the temperature sensor is balanced to determine whether the airtightness is qualified, that is, the upper computer can read the allowable pressure difference and allowable flow difference and compare them with the corresponding process requirements. For example, the pressure change ≤ 1‰ and the flow change ≤ 1.5‰. If satisfied, it uploads the data to the production management system and passes the station. If not satisfied, it sends an alarm signal to repair the pulse cleaning device.

[0038] After the airtightness of the pulse cleaning device is detected to be qualified and the detection pipeline component is not disconnected, after confirmation on the system interface, the upper computer can control the electromagnetic three-way valve to call the pulse cleaning generating component and the drainage and gas channels. After the pressure is sufficient, it opens the electromagnetic direct-through valve near the water-gas mixing tank to generate pulses. After the pulse pressure is qualified, it opens the electromagnetic direct-through valve of the water and gas inlet channel to perform pulse cleaning operations. After pulse cleaning, it reads relevant pressure data, such as the pressure gauge and pressure sensor data, and controls the electric proportional valve and the pressure relief valve to ensure the stability and safety of the pressure.

[0039] It should be noted that the airtightness detection and pulse cleaning operations performed on the product to be cleaned are consistent with the process of the airtightness detection and pulse cleaning operations of the pulse cleaning device for self-check. The difference is that the judgment of whether to pass is based on the corresponding process requirements. For example, the required pressure, the required pressure change and flow change values of the product to be cleaned. Generally, the product to be cleaned requires a pressure change ≤ 3‰ and a flow change ≤ 3‰. After uploading the process digital file for storage and verifying and judging to pass, the product to be cleaned can pass the station. In addition, after connecting a pair of detection pipelines, it is necessary to perform a barcode verification again to prevent misusage.

[0040] In practical applications, the inflation pressure and the cleaning pressure are monitored in real time by the host computer and adjusted according to the pressure required by the product. Generally, the product pressure does not exceed 3 MPa. For example, if the allowable pressure of the product is 2.0 - 2.5 MPa, when the range of the safety relief valve regulated by the host computer according to the pressure gauge is > 2.4 MPa, pressure relief is carried out, and the electromagnetic proportional valve is adjusted according to the pressure sensor to stabilize the pressure at 2.3 0.007 Mpa (three thousandths).

[0041] Furthermore, in specific implementation, in the above-mentioned equipment cleaning system provided by the embodiments of the present invention, the control circuit can also be used to start the corresponding high-pressure water pump and electromagnetic direct-through valve when the flow sensors around the pipe-type filter row of the water treatment component and the transfer water tank do not detect flow fluctuations after receiving the first instruction, so as to drain the liquid in the transfer water tank back to the clean water tank.

[0042] During implementation, after the flow sensors near the pipe-type filter row of the water treatment component and the transfer water tank do not detect flow fluctuations, the control circuit starts the corresponding high-pressure water pump and electromagnetic direct-through valve, drains the liquid in the transfer water tank back to the clean water tank, and conducts detection after the drainage is completed.

[0043] Furthermore, in specific implementation, in the above-mentioned equipment cleaning system provided by the embodiments of the present invention, the host computer is also used to read the temperature value and sensor values from the start to the completion of the pulse cleaning, take the sensor data within the preset cleaning duration for temperature factor correction, and determine whether the corrected sensor data meets the water quality requirements. If so, a stop instruction is sent 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 instruction is sent to the control circuit and an alarm is given.

[0044] During implementation, the host computer reads the temperature, TDS, ATP, and PH sensor values from the start to the completion of the pulse cleaning, takes the sensor data in the latter part (such as the last 10% of the time) within the preset cleaning duration (self-checking the second preset time value) for temperature factor correction. If the water quality requirements are met, such as TDS < 9 mg / L, total colony count < 100 CFU / mL, and PH < 7, it is determined that the pulse cleaning is qualified, and the process digital file is uploaded for storage. If not, repeated pulse cleaning is performed. If the cleaning exceeds the preset number of times, the device stops and gives an alarm.

[0045] The following uses a specific example to illustrate the operation process of the above-mentioned equipment cleaning system, which may specifically include:

[0046] When the pulse cleaning device conducts its own airtightness detection, the pipelines are connected, and the upper computer interface confirms the start of the device's self-check for airtightness; before and during inflation, the upper computer determines whether pressure relief operation is required based on the pressure sensor and pressure gauge, and issues parameters to the control circuit through the digital-to-analog converter according to process parameters such as the inflation pressure of the device. The upper computer checks whether the electromagnetic direct-acting valves on other pipelines unrelated to airtightness are closed, whether the direction of the electromagnetic three-way valve is correct, and makes corrections. When the upper computer starts the inflation generating component, it opens the corresponding gas source management unit, allowing the gas to pass through the hand-operated slide valve, gas source processor, and gas source management unit in sequence. When starting the inflation generating component, it opens the direction of the corresponding electromagnetic three-way valve and the electromagnetic direct-acting valve before the sub-channel, so that after the gas passes through the hand-operated slide valve, gas source processor, and gas source management unit, it passes through the electromagnetic proportional valve, dryer, pressure gauge, and electromagnetic three-way valve to the detection management component in sequence. When starting the inflation generating component, it opens the electromagnetic direct-acting valve obtained from the corresponding detection pipeline component channel and the direction of the corresponding electromagnetic three-way valve, allowing the gas to pass through temperature sensors, ultrasonic sensors, flow sensors, pressure sensors, etc., and ensuring the channel pressure through the electromagnetic proportional valve; after passing through the pressure reducing valve, dryer, humidity sensor, gas concentration sensor, check valve in the return air channel, it conducts common return air through the electromagnetic three-way valve; then continue to inflate until after temperature correction. When the humidity sensor value ≤ 3RH, inflate for 30s. After temperature correction, when the ultrasonic sensor value ≤ 1RH, continue to inflate and adjust the opening of the electromagnetic proportional valve until the pressure sensor reaches the preset pressure value. After standing for 5 minutes, when the pressure change of the pressure sensor ≤ 1‰ and the change of the flow sensor ≤ 1.5‰, it is determined that the airtightness detection is qualified.

[0047] When conducting airtightness detection on the equipment to be cleaned, the process is the same as above, except that the pipeline of the equipment to be cleaned needs to be connected to the detection pipeline of the pulse cleaning device first; in the subsequent steps, continue to inflate until after temperature correction. When the humidity sensor value ≤ 3.5RH, inflate for 30s. After temperature correction, when the ultrasonic sensor value ≤ 1.5RH, continue to inflate and adjust the opening of the electromagnetic proportional valve until the pressure sensor reaches the preset pressure value. After standing for 5 minutes, when the pressure change of the pressure sensor ≤ 3‰ and the change of the flow sensor ≤ 3‰, it is determined that the airtightness detection is qualified.

[0048] When the pulse cleaning device performs its own pulse cleaning operation, the pipeline remains connected. The host computer interface confirms the start of the device self-check pulse cleaning. Before and during cleaning, the host computer determines whether pressure relief is required based on the pressure sensor and pressure gauge, and issues parameters to the control circuit through the digital-to-analog converter according to process parameters such as the cleaning pressure of the device. The host computer checks whether the electromagnetic direct-acting valves on other pulse-unrelated pipelines are closed and whether the electromagnetic three-way valves are in the correct position, and makes corrections. When the host computer starts the pulse cleaning generating component, it simultaneously opens the solenoid valves, high-pressure pumps, etc. from the clean water tank and the air source to the water-air mixing tank. When the pressure in the water-air mixing tank reaches a certain value, the electromagnetic direct-acting valve and the booster pump behind the water-air mixing tank are opened; when the booster pump exceeds the safety pressure, pressure relief is performed, and the water-air mixed fluid passes through the oscillator and the pulse generator in sequence. After ensuring the pressure of the entire detection pipeline component through the electromagnetic proportional valve, it enters the detection pipeline component through the electromagnetic three-way valve. When starting the pulse cleaning generating component, the electromagnetic direct-acting valve of the corresponding detection pipeline component channel and the direction of the corresponding electromagnetic three-way valve are opened, so that the high-pressure water-air mixed fluid gas passes through the temperature sensor, ultrasonic sensor, flow sensor, pressure sensor, etc., and the pressure of this channel is ensured through the electromagnetic proportional valve. After passing through the pressure reducing valve, temperature sensor, PH sensor, TDS sensor, ATP sensor, check valve of the drain air channel, it enters the common drain air channel through the electromagnetic three-way valve and is continuously cleaned for 5 minutes. The data of the temperature sensor, PH sensor, TDS sensor, and ATP sensor within the last 10% of the time is intercepted. If the TDS after temperature correction < 9mg / L, the total colony count < 100CFU / mL, and PH < 7, it is determined that the pulse cleaning is qualified.

[0049] For the pulse cleaning operation of the equipment to be cleaned, the process is the same as above, 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 the actual situation.

[0050] It should be added that when the pulse cleaning device does not receive instructions such as inflation and pulse cleaning, in the non-automatic water injection mode, the water inlet is sealed, the flowmeter has no changing value, and the host computer can send instructions to the PLC to close the safety solenoid valve to prevent water and gas from entering. If it is detected that the liquid level in the clean water tank is insufficient (the second liquid level warning value), the host computer prompts to add water. If it is detected that the liquid level in the clean water tank is insufficient (the third liquid level warning value), an alarm is given and inflation and pulse cleaning instructions cannot be executed. When the device does not receive instructions such as inflation and pulse cleaning, in the automatic water injection mode, if it is detected that the liquid level in the clean water tank is insufficient (the second liquid level warning value), the solenoid valve, booster pump, and safety solenoid valve are opened to start the pure water delivery. After adding water to a certain extent (the first liquid level warning value), the solenoid valve, booster pump, and safety solenoid valve are closed.

[0051] After the water quality monitoring in the water purification tank is set for a period of time (such as 5 minutes), if the TDS after temperature correction < 9 mg / L, the total number of colonies < 100 CFU / mL, and the PH < 7, it is determined that the water quality is qualified. When pulse cleaning occurs, the electromagnetic direct valve and high-pressure pump can be opened to transport water to the water-gas mixing tank.

[0052] If one of the above three parameters is unqualified, open the electromagnetic direct valve, high-pressure pump, and electromagnetic direct valve, and drain the water in the water purification tank through the pipeline-type filter row, activated carbon filter, and ultraviolet disinfection to the transfer water tank in sequence. When there is no obvious increase in the liquid level sensor in the transfer water tank (k < 10 ml / s) and no obvious decrease in the liquid level sensor in the water purification tank (k < 10 ml / s), and then the flowmeter on the drainage route from the water purification tank to the transfer water tank (the flowmeter value is close to 0 or < 5 ml / s), close the electromagnetic direct valve and high-pressure pump on the route from the water purification tank to the transfer water tank, open the electromagnetic direct valve and constant pressure pump from the transfer water tank to the water purification tank, and introduce the purified water into the water purification tank. At the same time, when draining, according to whether the pressure of the pressure gauge near the high-pressure pump exceeds the safety value, determine whether to start the safety relief valve to relieve pressure and adjust the speed of the high-pressure pump through the frequency converter.

[0053] If there is no obvious decrease in the liquid level of the transfer water tank (k < 10 ml / s) and no obvious increase in the liquid level of the water purification tank (k < 10 ml / s), and the values of the two flowmeters from the transfer water tank to the water purification tank are close to 0 or < 5 ml / s, stop the electromagnetic direct valve and constant pressure pump.

[0054] Then, after 5 minutes of water quality monitoring in the water purification tank, if the TDS after temperature correction < 9 mg / L, the total number of colonies < 100 CFU / mL, and the PH < 7, it is determined that the water quality is qualified. If it is unqualified, continue to repeat the above process. After the counting times exceed the preset 5 times (adjustable, such as ≤ 5), the device stops and alarms, takes samples for inspection, and analyzes the corresponding parameters.

[0055] The embodiment of the present invention also provides a cleaning method for an equipment cleaning system. Figure 5 It is a flowchart of the cleaning method for the equipment cleaning system provided by the embodiment of the present invention. As Figure 5 shown, the method includes: S501.
