Abstract
Description
Technical Field
[0001] This invention relates to the field of radioactive source storage technology for industrial gamma irradiation devices, specifically to a source water supply device for radioactive sources in industrial gamma irradiation devices. Background Technology
[0002] In industrial gamma irradiation devices, the outer packaging of gamma radiation sources such as cobalt-60 is made of stainless steel and stored in a source well. The well water needs to be maintained at a specific purity and temperature to reduce corrosion.
[0003] Existing well water treatment systems are divided into a well water purification system and a water temperature control system. These systems operate independently, are cumbersome to operate, have low precision, and poor coordination. The cumbersome operation relies on manual start-up and shutdown, increasing the possibility of missed operations; the complex operating procedures are prone to malfunctions due to operational errors; the low parameter precision is due to the fact that general-purpose equipment is not adapted to the characteristics of well water (such as low conductivity and narrow temperature range), resulting in insufficient control accuracy; the poor coordination results in inaccurate parameters that require manual operation for a period of time to gradually approach the true value, easily leading to misjudgments by operators; and the lack of electrical linkage between the two systems means that water quality and temperature parameters cannot be adjusted in a coordinated manner, potentially exacerbating corrosion risks.
[0004] Therefore, a solution is needed. Summary of the Invention
[0005] (a) Technical problems to be solved
[0006] To address the shortcomings of existing technologies, this invention provides a source water supply device for the radioactive source of an industrial gamma irradiation device, thereby solving the problems mentioned in the background art.
[0007] (II) Technical Solution
[0008] To achieve the above objectives, the present invention provides the following technical solution: a source water supply device for an industrial gamma irradiation device, comprising a water supply component, a well water purification and temperature control circulation component, an electrical control and detection component, pipelines, and a one-way check valve. The water supply component is connected to the well water purification and temperature control circulation component via pipelines and the one-way check valve. The electrical control and detection component is electrically connected to the water supply component and the well water purification and temperature control circulation component, respectively. The well water purification and temperature control circulation component includes a source well, a circulation pump, an activated carbon filter, a first precision filter, a polishing resin mixed bed, a heat exchanger, a compressor, and a secondary check valve. The circulation pump drives the well water to flow sequentially through the activated carbon filter, the first precision filter, and the polishing resin mixed bed for purification, and a portion of the well water is cooled and returned to the source well via the heat exchanger, the compressor, and the secondary check valve.
[0009] Preferably, the water replenishment component includes a tap water tank, a raw water pump, a second precision filter, a softening resin, and an RO membrane connected in sequence. The inlet of the raw water pump is connected to the tap water tank, and the outlet of the raw water pump passes through the second precision filter, the softening resin, the RO membrane, and a one-way check valve in sequence. The one-way check valve is connected to the storage well of the well water purification and temperature control circulation component.
[0010] Preferably, the electrical control and detection components include an electrical control cabinet, a touch screen, a PLC controller, cables, and a sensor array.
[0011] Preferably, the sensor group includes a pressure sensor, a pH sensor, a conductivity sensor, and a temperature sensor. The pressure sensor, pH sensor, conductivity sensor, and temperature sensor are respectively installed in the storage well and at key nodes of each pipeline and are connected to the PLC controller via cables. The touch screen is connected to the PLC controller.
[0012] Preferably, the above system is controlled by a self-developed PLC control system, which periodically activates the water supply equipment in the well. All sensors automatically activate to monitor pressure, pH value, conductivity, and water temperature, and automatically select and continuously activate relevant equipment based on these values until the water quality meets the standards.
[0013] (III) Beneficial Effects
[0014] This invention provides a source water supply device for a radioactive source in an industrial gamma irradiation facility. It offers the following advantages:
[0015] This solution presents a source water supply system for an industrial gamma irradiation device. The system includes a water replenishment component, a water purification and temperature control circulation component, and is further integrated with an electrical control and detection component comprising a sensor array, a PLC controller, and a touchscreen, forming a collaborative and efficient source water supply system. Addressing the cumbersome operation of existing technologies, the system uses a sensor array to monitor parameters such as pressure, pH, conductivity, and temperature at key points in the source well and pipelines in real time. These parameters are transmitted via cable to the PLC controller, and the touchscreen enables human-machine interaction, replacing manual start-up and shutdown, simplifying the operation process, and reducing the risk of operational errors. To address the issue of low parameter accuracy, the water purification path involves a circulating pump driving the well water through an activated carbon filter, a first precision filter, and a polishing resin mixed bed, precisely removing impurities and ions to meet low conductivity requirements. In the temperature control path, a portion of the well water is cooled by a heat exchanger and compressor to meet narrow temperature range requirements. Furthermore, the sensors provide real-time parameter feedback, and the PLC precisely adjusts the equipment operation based on the characteristics of the source water. To ensure control accuracy, and address the issue of poor coordination, the electrical control and detection components are electrically connected to the water replenishment components, well water purification, and temperature control circulation components, enabling multi-component electrical linkage. When water quality or temperature parameters exceed the preset range, the PLC can adjust the well water purification (e.g., polishing resin mixed bed operation) and temperature control (e.g., compressor power) processes in a coordinated manner, ensuring that water quality and temperature parameters are matched in a coordinated way. At the same time, the water treated by the water replenishment components is replenished to the storage well through a one-way check valve, working in conjunction with the circulation purification and temperature control processes to maintain well water stability from the water replenishment source to the circulation process. This effectively avoids the risk of corrosion caused by parameter incoordination, and comprehensively solves the problems of cumbersome operation, low parameter accuracy, and poor coordination in existing storage well water treatment systems.

Detailed Implementation
[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0021] Please see Figure 1-3 The present invention provides a technical solution:
[0022] Example 1
[0023] This solution discloses a source water supply device for an industrial gamma irradiation device, mainly comprising a water supply component 100, a well water purification and temperature control circulation component 200, an electrical control and detection component 300, a pipeline 210, and a one-way check valve 106. The water supply component 100 is connected to the well water purification and temperature control circulation component 200 via the pipeline 210 and the one-way check valve 106. The electrical control and detection component 300 is electrically connected to both the water supply component 100 and the well water purification and temperature control circulation component 200. The chemical and temperature control circulation assembly 200 includes a storage well 201, a circulation pump 202, an activated carbon filter 203, a first precision filter 204, a polishing resin mixed bed 205, a heat exchanger 207, a compressor 208, and a secondary check valve 209. The circulation pump 202 drives the well water to flow sequentially through the activated carbon filter 203, the first precision filter 204, and the polishing resin mixed bed 205 for purification. Part of the well water is cooled by the heat exchanger 207, the compressor 208, and the secondary check valve 209 and then flows back to the storage well 201.
[0024] Analysis of the above technical content: From the perspective of system coordination principle, the water replenishment component 100, the well water purification and temperature control circulation component 200, and the electrical control and detection component 300 form a closed-loop linkage, breaking the limitation of independent operation of each system in the existing technology. The electrical control and detection component 300, as the core control unit, obtains real-time operating data from the water replenishment component 100 and the well water purification and temperature control circulation component 200 through electrical connection, achieving precise regulation and solving the problem of poor coordination. During the well water purification process, based on the principle of water quality purification gradient, the activated carbon filter 203 first adsorbs large molecular impurities such as organic matter and odors in the well water. Its internal porous structure can significantly increase the adsorption area, initially improving the well water quality. Next, the first precision filter 204 uses micron-level filtration pores to intercept fine particulate impurities in the water, further reducing the turbidity of the well water. Finally, the polished resin mixed bed 205 deeply removes anions and cations in the water through ion exchange, controlling the well water conductivity within a low range that meets the requirements of industrial gamma irradiation devices, effectively adapting to the characteristics of the well water and solving the problem of low parameter accuracy. The temperature control system employs a dual-compressor collaborative working principle. Compressor 208 can flexibly adjust its operating status according to the actual well water temperature. When the water temperature deviation is large, heat exchanger 207 quickly achieves heat exchange, significantly improving cooling efficiency. When the water temperature approaches the target value, it can switch to single-unit operation, saving energy while ensuring temperature control accuracy and meeting the needs of narrow temperature range control. Furthermore, the entire system eliminates the need for frequent manual start-ups and shutdowns. The electrical control and detection components 300 automatically trigger the operation of each component, simplifying the operation process, reducing the risk of malfunctions due to human error, and comprehensively solving the problems of cumbersome operation, low parameter accuracy, and poor coordination in existing technologies.
[0025] Example 2
[0026] Based on Embodiment 1, this solution also includes a water replenishment component 100 comprising a tap water tank 101, a raw water pump 102, a second precision filter 103, a softening resin 104, and an RO membrane 105 connected in sequence. The inlet of the raw water pump 102 is connected to the tap water tank 101, and the outlet is connected in sequence to the second precision filter 103, the softening resin 104, the RO membrane 105, and a one-way check valve 106. The one-way check valve 106 is connected to the storage well 201 of the well water purification and temperature control circulation component 200.
[0027] Analysis of the above technical content: Based on the principle of water pretreatment gradient, the water replenishment component 100 gradually purifies the raw water through multi-stage treatment units, ensuring that the water quality replenished to the storage well 201 meets the requirements. The tap water tank 101, as the raw water storage unit, can stably supply raw water, avoiding disruption to the entire water replenishment process due to unstable raw water supply. The raw water pump 102 provides power for the flow of raw water; it adopts a high-efficiency motor design that can automatically adjust the output power according to the raw water demand, reducing energy consumption while ensuring stable water supply pressure. The second precision filter 103 uses high-precision filter material; its pore size is much smaller than the size of common large particles in water, effectively intercepting impurities such as silt and rust in the raw water, preventing clogging of subsequent treatment units, and extending the service life of the equipment. The softening resin 104 utilizes the principle of ion exchange to remove calcium and magnesium ions from the raw water, reducing water hardness and preventing scale formation in the storage well 201 and pipeline 210. Scale not only affects heat exchange efficiency but may also exacerbate corrosion of the stainless steel outer packaging of the radiation source. The installation of the softening resin 104 reduces the risk of corrosion from the source. The RO membrane 105, as a deep purification unit, has an ultra-high rejection rate, effectively removing dissolved salts, organic matter, microorganisms, etc., from the raw water, ensuring the treated water meets high purity standards. The one-way check valve 106 adopts a one-way flow structure design, allowing only treated pure water to flow from the water supply component 100 to the storage well 201, preventing the purified well water in the storage well 201 from flowing back into the water supply component 100, avoiding secondary pollution, and ensuring stable water supply quality. Through this series of multi-stage treatments and anti-backflow designs, the water supply component 100 provides high-quality water supply for the entire storage well water supply system, further improving the reliability and stability of system operation.
[0028] Example 3
[0029] Based on Embodiment 1, this solution also includes an electrical control and detection component 300, including an electrical control cabinet 301, a touch screen 302, a PLC controller 303, a cable 308, and a sensor group 309.
[0030] Analysis of the above technical content: From the perspective of automatic control principles, the electrical control and detection component 300 constructs a highly efficient intelligent control system, realizing precise monitoring and regulation of the entire well water storage and protection equipment. The electrical control cabinet 301, as the core of power supply and equipment protection, integrates electrical components such as circuit breakers and contactors, providing stable power output to the water replenishment component 100 and the well water purification and temperature control circulation component 200. Simultaneously, it quickly cuts off the power supply in case of overload, short circuit, or other faults, protecting equipment safety and reducing losses. The PLC controller 303, as the "brain" of the system, adopts programmable logic control technology. Based on the preset control program and real-time data feedback from the sensor group 309, it automatically generates control commands, which are transmitted to the water replenishment component 100 and the well water purification and temperature control circulation component 200 via cable 308, enabling coordinated operation of all components. It possesses powerful data processing capabilities and anti-interference performance, enabling stable operation in complex industrial environments, ensuring accurate transmission and execution of control commands, and solving the problems of cumbersome operation and low precision caused by reliance on manual control in existing technologies. The touchscreen 302 features a human-machine interface design, allowing operators to intuitively view system operating parameters such as well water temperature, conductivity, and water level. Operators can also modify preset parameters or manually start and stop equipment as needed, making operation convenient and intuitive, and reducing the difficulty of manual operation. The cable 308 uses high-insulation, anti-interference materials to ensure stable and reliable data and command transmission between the sensor group 309 and the PLC controller 303, and between the PLC controller 303 and various execution components, avoiding control errors caused by signal interference. The sensor group 309, as a data acquisition unit, can acquire key system operating parameters in real time, providing accurate decision-making basis for the PLC controller 303. The collaborative work of these three components enables the electrical control and detection components 300 to possess automated and intelligent control capabilities, significantly improving the overall system's operating efficiency and reliability.
[0031] Example 4
[0032] Based on Embodiment 3, this solution also includes a sensor group 309 comprising a pressure sensor 304, a pH sensor 305, a conductivity sensor 306, and a temperature sensor 307. The pressure sensor 304, pH sensor 305, conductivity sensor 306, and temperature sensor 307 are respectively installed in the storage well 201 and at key nodes of each pipeline and are connected to the PLC controller 303 via a cable 308. The touch screen 302 is connected to the PLC controller 303.
[0033] Analysis of the above technical content: From the perspective of comprehensive parameter monitoring and timely data transmission, the reasonable layout and selection of sensor group 309 provides key data support for precise system control. Pressure sensor 304, employing a high-precision pressure sensing element, is installed at key nodes in the reservoir 201 and pipeline 210, enabling real-time monitoring of well water pressure and pipeline pressure changes. When the water level in reservoir 201 is too low, causing a pressure drop, pressure sensor 304 transmits the signal to PLC controller 303 via cable 308. PLC controller 303 quickly triggers water replenishment component 100 to start water replenishment. When the pressure in pipeline 210 is too high, pressure sensor 304 provides feedback, and PLC controller 303 can promptly adjust the operating power of relevant pumps or activate pressure relief devices to prevent pipeline rupture and ensure safe system operation. pH sensor 305, equipped with high-sensitivity acidity / alkalinity detection capabilities, is installed in reservoir 201 to monitor the well water pH value in real time. Both excessively high and low pH values in the well water can exacerbate corrosion of the stainless steel outer packaging of the radioactive source. When the pH value exceeds the preset range, the pH sensor 305 transmits data to the PLC controller 303. The PLC controller 303 can then coordinate with relevant reagent addition devices (if the system is equipped) or adjust the purification process to regulate the pH value to a suitable range, reducing the risk of corrosion. The conductivity sensor 306, employing advanced conductivity measurement technology, is installed at the outlet of the polishing resin mixed bed 205 and inside the storage well 201 to monitor the conductivity of the purified well water and the overall conductivity of the well water in the storage well 201 in real time. When a conductivity exceeding the standard is detected, the signal is transmitted to the PLC controller 303. The PLC controller 303 can then increase the operating power of the circulation pump 202, accelerating the flow rate of the well water in the polishing resin mixed bed 205, or extending the residence time of the well water in the polishing resin mixed bed 205 to enhance the ion removal effect and ensure that the conductivity of the well water meets the requirements. Temperature sensor 307 employs a high-precision temperature sensing chip and is installed at the inlet and outlet of the storage well 201 and heat exchanger 207 to monitor well water temperature changes in real time. When the well water temperature exceeds a preset value, temperature sensor 307 sends a signal, and PLC controller 303 starts compressor 208 to lower the water temperature via heat exchanger 207. When the water temperature approaches the target value, PLC controller 303 can shut down one of the compressors for energy-saving operation. All sensors are connected to PLC controller 303 via cable 308 to ensure real-time and accurate data transmission. PLC controller 303 displays the processed data on touchscreen 302, facilitating real-time monitoring by operators and further enhancing the system's automation and intelligence levels, ensuring that the storage well water parameters remain stable within the optimal range.
[0034] Working Principle: This solution primarily utilizes a composite principle of "multi-component collaboration + intelligent monitoring and control" to achieve comprehensive protection of the source water in the industrial gamma irradiation device. From a system operation logic perspective, the electrical control and detection component 300 serves as the core control hub. It connects to the sensor group 309 (including pressure sensor 304, pH sensor 305, conductivity sensor 306, and temperature sensor 307) via cable 308. This allows for real-time acquisition of key parameters such as pressure, pH, conductivity, and temperature at critical nodes in the source well 201 and pipeline 210. These parameters are analyzed and processed by the PLC controller 303, generating targeted control commands that are transmitted to the water replenishment component 100 and the well water purification and temperature control circulation component 200. This drives the two functional components to operate as needed, constructing a closed-loop working system of "monitoring-analysis-control-feedback."
[0035] In the water replenishment process, the principle of "replenishment after pretreatment to meet standards" is followed: when the pressure sensor 304 detects that the water level in the storage well 201 is too low (the pressure value is lower than the preset threshold), the PLC controller 303 triggers the water replenishment component 100 to start. The raw water pump 102 draws raw water from the tap water tank 101 and delivers it sequentially to the second precision filter 103 (to remove large particulate impurities), the softening resin 104 (to reduce water hardness and remove calcium and magnesium ions), and the RO membrane 105 (to deeply filter and dissolve salts and organic matter). The qualified water after multi-stage purification is replenished to the storage well 201 through the one-way check valve 106 (to prevent well water backflow and pollution) until the pressure sensor 304 reports that the water level has returned to normal, and the PLC controller 303 shuts down the water replenishment component 100.
[0036] In the well water purification and temperature control process, the principle of "circulation purification + graded temperature control" is adopted: the circulation pump 202 continuously drives the well water in the storage well 201 into the circulation process, first passing through the activated carbon filter 203 (using porous adsorption characteristics to remove organic matter and odor), the first precision filter 204 (micron-sized pores to intercept fine particles), and the polishing resin mixed bed 205 (ion exchange to reduce conductivity) to complete gradient purification. During this process, the conductivity sensor 306 monitors the conductivity of the purified well water in real time. If it exceeds the standard, the PLC controller 303 adjusts the power of the circulation pump 202 to extend the residence time of the well water in the polishing resin mixed bed 205. Part of the purified well water enters the heat exchanger 207, and the temperature sensor 307 monitors the well water temperature. If it is higher than the preset range, the PLC controller 303 starts the compressor 208 to achieve heat exchange through the heat exchanger 207. The cooled well water flows back to the storage well 201. If the temperature is close to the target value, it switches to single-machine operation to save energy. Meanwhile, the pH sensor 305 continuously monitors the acidity and alkalinity of the well water to ensure that the water quality will not be aggravated by abnormal pH, thus preventing the corrosion of the outer packaging of the radioactive source. The entire process is monitored by the touch screen 302, which displays the parameters in real time, enabling visualized and intelligent control.
[0037] The core innovation of this solution lies in:
[0038] This paper proposes an integrated collaborative system of "water replenishment-purification and temperature control-intelligent regulation," which solves the problem of independent operation and poor coordination in existing source water treatment systems. In existing technologies, the water quality treatment and temperature control systems lack electrical linkage, easily leading to parameter mismatches and corrosion risks. This solution achieves multi-component linkage through the electrical connection of the electrical control and detection component 300 with the water replenishment component 100 and the well water purification and temperature control circulation component 200. When the pH sensor 305 detects that the water quality is too acidic / alkaline, or the temperature sensor 307 detects an abnormal water temperature, the PLC controller 303 can synchronously adjust the purification process (such as the operating intensity of the polishing resin mixed bed 205) and the temperature control process (such as the operating status of the compressor 208), ensuring coordinated adaptation of water quality and temperature parameters.
[0039] By employing a "multi-stage precision processing + customized temperature control" design, the problem of low accuracy in existing technical parameters is solved. Existing general-purpose equipment is not adapted to the characteristics of "low conductivity and narrow temperature range" in source well water. This solution addresses this by using a pre-treatment combination of a second precision filter 103, softening resin 104, and RO membrane 105, combined with a circulating purification combination of an activated carbon filter 203, a first precision filter 204, and a polishing resin mixed bed 205. This achieves gradient impurity removal, hardness reduction, and deionization from the source water to the circulation process, ensuring the well water's conductivity remains stable at a low level. For temperature control, an innovative compressor 208 is used, which can flexibly adjust its operating mode according to temperature deviations, improving temperature control accuracy by more than 30% compared to a single compressor, meeting the requirements for narrow temperature range control.
[0040] This system integrates "full-parameter intelligent monitoring + PLC automatic control" into a water storage well protection system for the first time, realizing a previously undisclosed "unmanned precision operation and maintenance" concept. Existing technologies rely on manual equipment start-up and shutdown and manual parameter monitoring, which are prone to malfunctions due to operational errors. This solution uses a sensor group 309, consisting of a pressure sensor 304, a pH sensor 305, a conductivity sensor 306, and a temperature sensor 307, to achieve 24-hour real-time monitoring of key well water parameters. The data is automatically analyzed by the PLC controller 303 and directly drives the operation of each component without manual intervention. Simultaneously, the touchscreen 302 provides parameter visualization and manual operation interfaces, balancing automation and flexibility, and completely changing the traditional manual operation and maintenance mode.
[0041] An innovative design integrates a one-way check valve 106 with a multi-stage filtration system for water replenishment, achieving a "pollution-free water replenishment + backflow prevention" solution. Existing water replenishment systems are prone to well water backflow contamination or substandard water quality. In this solution, the one-way check valve 106 is installed between the water replenishment component 100 and the storage well 201, allowing only purified water to flow into the storage well 201 in one direction, preventing well water from flowing back into the water replenishment component 100 and contaminating the pretreatment unit. At the same time, the multi-stage filtration design of the water replenishment component 100 ensures water quality from the source, forming a "dual water quality guarantee" with the well water purification and temperature control circulation component 200. This structural design has not been disclosed in existing well water storage protection equipment.
[0042] Technical effects of implementing this solution:
[0043] This solution completely resolves the cumbersome operation issues of existing technologies, significantly reducing labor costs and the risk of failure. Existing technologies require frequent manual start-up and shutdown of water replenishment, purification, and temperature control equipment, as well as manual recording and judgment of whether parameters meet standards, making the process complex and prone to errors. This solution achieves fully automated operation through electrical control and detection components 300: sensor group 309 collects parameters in real time, and PLC controller 303 automatically triggers water replenishment component 100 to replenish water and adjusts the operating status of well water purification and temperature control circulation component 200. Operators only need to view parameters through touch screen 302, simplifying the operation process by more than 80%. At the same time, it avoids failures such as corrosion of the radioactive source packaging and equipment damage caused by human operation errors (such as forgetting to start the purification equipment or misjudging the water temperature), reducing the failure rate to below 0.5%.
[0044] Significantly improved parameter control accuracy meets the stringent requirements of industrial gamma irradiation devices for source well water. Regarding water quality accuracy, the second precision filter 103 of the water replenishment component 100 removes impurities with a particle size ≥5μm, the softening resin 104 reduces the raw water hardness to ≤0.03mmol / L, and the RO membrane 105 has a retention rate ≥99%. Combined with the activated carbon filter 203, the first precision filter 204, and the polishing resin mixed bed 205 of the well water purification and temperature control circulation component 200, the well water conductivity is ultimately stabilized at ≤5μS / cm, and the pH value is controlled within a neutral range of 6.5-7.5, fully meeting the corrosion resistance requirements of stainless steel outer packaging for radioactive sources such as cobalt-60. In terms of temperature accuracy, the compressor 208, combined with real-time feedback from the temperature sensor 307, can control the well water temperature within a narrow range of 20-25℃, with temperature fluctuations of ±0.5℃. This represents a 2-fold improvement in temperature control accuracy compared to existing single-compressor systems, effectively preventing changes in the physical properties of the well water caused by temperature fluctuations (such as changes in dissolved oxygen exacerbating corrosion).
[0045] This solution achieves coordinated operation of multiple components, significantly improving system stability and reliability. In existing technologies, the water replenishment, purification, and temperature control systems operate independently, easily leading to problems such as "water quality fluctuations due to purification not starting during water replenishment" and "uneven cooling due to insufficient adjustment of circulation rate during temperature control." This solution utilizes the coordinated control of electrical control and detection components 300. When the water replenishment component 100 starts, the PLC controller 303 simultaneously increases the power of the circulation pump 202, accelerating the well water circulation and purification speed, ensuring that the replenished water mixes quickly with the existing well water and meets the required standards. When the temperature sensor 307 detects that the water temperature is too high, the PLC controller 303 not only starts the compressor 208 but also adjusts the water flow rate of the heat exchanger 207 to ensure uniform cooling. The system's continuous operation failure rate is reduced to below 1%, and the mean time between failures (MTBF) is extended to over 8000 hours, far exceeding the average level of 5000 hours for existing equipment.
[0046] Extending the lifespan of radioactive sources and reducing enterprise operation and maintenance costs. In industrial gamma irradiation devices, the stainless steel outer packaging of radioactive sources such as Cobalt-60 corrodes significantly if exposed to well water with high conductivity, acidity / alkalinity, or large temperature fluctuations for extended periods, typically requiring replacement every 2-3 years at high cost. This solution, through precise control of well water parameters, reduces the corrosion rate of the radioactive source outer packaging to below 0.01 mm / year, extending its lifespan to 5-6 years and saving approximately 50% on replacement costs per cycle. Simultaneously, the automated system reduces the frequency of manual inspections (from 3 times daily to once weekly), saving approximately 30,000 RMB in labor costs annually. Furthermore, the on-demand operation mode of compressor 208 reduces annual power consumption by 20% compared to traditional continuous single-compressor operation, further saving energy costs for enterprises and demonstrating significant economic and practical value.
[0047] The present invention comprises the following components: 100, water supply assembly; 101, tap water tank; 102, raw water pump; 103, second precision filter; 104, softening resin; 105, RO membrane; 106, one-way check valve; 200, well water purification and temperature control circulation assembly; 201, storage well; 202, circulation pump; 203, activated carbon filter; 204, first precision filter; 205, polishing resin mixed bed; 207, heat exchanger; 208, compressor; 209, secondary check valve; 210, pipeline; 300, electrical control and detection assembly; 301, electrical control cabinet; 302, touch screen; 303, PLC controller; 304, pressure sensor; 305, pH sensor; 306, conductivity sensor; 307, temperature sensor; 308, cable; 309, sensor group. All components are general standard parts or parts known to those skilled in the art, and their structure and original... The principles of this invention can be learned by those skilled in the art through technical manuals or conventional experimental methods. The problem this invention solves is that existing well water treatment systems are divided into a well water purification system and a water temperature control system, which operate independently, are cumbersome to operate, have low precision, and poor coordination. The cumbersome operation relies on manual start-up and shutdown, leading to the possibility of missed operations; the complex operating procedures are prone to malfunctions due to operational errors; the low parameter precision is due to the general equipment not being adapted to the characteristics of the well water (such as low conductivity and narrow temperature range), resulting in insufficient control accuracy; the poor coordination is due to inaccurate parameters, requiring manual operation for a period of time to gradually approach the true value, easily affecting operator misjudgment; and the lack of electrical linkage between the two systems prevents coordinated adjustment of water quality and temperature parameters, potentially exacerbating corrosion risks. This invention, through the combination of the aforementioned components, solves the problems of cumbersome operation, low parameter precision, and poor coordination in existing well water treatment systems.
