Description

Technical Field

[0001] This utility model relates to a reclaimed water treatment system. Background Technology

[0002] With the continuous development of industrialization, water scarcity and water pollution have become increasingly serious problems. Water, as an important natural resource, is widely used in the production processes of various industries, especially in chemical, power, pharmaceutical, and metallurgical industries. However, as production processes continue, the problems of large-scale wastewater discharge and water waste have gradually emerged. In particular, some water used in water treatment and cleaning processes cannot be effectively recycled, resulting in water waste and increased related costs.

[0003] During the use of ion exchangers, regeneration requires a large amount of water for rinsing. Most of the rinsing water generated during regeneration can actually be recycled and reused, but many companies are currently failing to fully utilize this rinsing water. The existing practice is to directly discharge the rinsing water generated during ion exchanger regeneration into a chemical wastewater pond, then treat it through a production wastewater treatment system before discharging it into the municipal sewer network. This practice not only wastes water resources but also increases water resource costs, water production costs, and wastewater treatment costs, placing a significant economic burden on companies.

[0004] Furthermore, excessive wastewater discharge can also have a negative impact on the ecological environment, especially in water-scarce areas. Wastewater discharge not only increases treatment costs but may also pose a potential threat to local water quality. Therefore, effectively recycling and utilizing rinse water during the regeneration process of ion exchangers is not only helpful in reducing production costs for enterprises but also aligns with current environmental protection concepts of energy conservation, emission reduction, and resource recycling, making it an urgent issue to be addressed. Utility Model Content

[0005] The purpose of this utility model is to provide a reclaimed water treatment system that utilizes an ultrafiltration recovery water tank to reclaim water for use in the pretreatment of raw water. Two gate valves are added to the connection between the ultrafiltration recovery water tank ditch and the chemical wastewater tank ditch. One gate valve is added at the inlet of the chemical wastewater tank, and the other is added at the connection between the ultrafiltration recovery water tank ditch and the chemical wastewater tank ditch. When the reclaimed flushing water is combined with the online instrument of the ion exchanger, the valve is switched to reclaim and reuse the water.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A reclaimed water treatment system, comprising:

[0008] Ion exchangers are used for water treatment and to produce regenerated flushing water.

[0009] Ultrafiltration recovery tank is used to recover and store reusable water;

[0010] Chemical wastewater ponds are used to store and treat discharged wastewater.

[0011] Two slide gate valves are respectively located at:

[0012] The connection point between the ultrafiltration recovery water tank and the chemical wastewater tank ditch;

[0013] At the inlet of the chemical wastewater tank, a device is used to control the switching of water flow direction;

[0014] Online instruments are used to monitor the operating data of the ion exchanger in real time and determine whether to recycle or discharge the regeneration flushing water into the wastewater pond based on the data.

[0015] Preferably, the slide gate valve includes a valve body and a drive mechanism for controlling the opening and closing of the valve body. The valve body includes a slide gate, a slide gate channel for accommodating the slide gate, medium channels disposed on both sides of the slide gate, and a sealing element disposed on the slide gate for forming an effective seal between the slide gate and the valve body.

[0016] Preferably, the seal is located on both sides of the insert plate and is snapped into the insert plate channel; the seal is a rubber seal.

[0017] Preferably, the medium channel is a circular channel, and the medium channel is connected to the connection point between the ultrafiltration recovery water tank and the chemical wastewater tank ditch, and to the pipe at the inlet of the chemical wastewater tank.

[0018] Preferably, the drive mechanism includes a cylinder for controlling the lifting and lowering of the slide plate, and a solenoid valve disposed on one side of the cylinder for controlling the cylinder drive.

[0019] Preferably, an upper sealing connector and a lower sealing connector are provided between the insert plate channel and the cylinder, and the upper sealing connector and the lower sealing connector are fixed together by bolts, and a sealing ring is provided between the upper sealing connector and the lower sealing connector.

[0020] Preferably, the cylinder is a double-acting cylinder capable of driving the slide plate in both directions to perform switching operations.

[0021] Preferably, the solenoid valve is a programmable solenoid valve that can adjust the valve's opening and closing state according to real-time data from online instruments.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] Most of the flushing water generated during the regeneration process of ion exchangers can be recycled and reused, but traditionally it is directly discharged, leading to water waste. This system, by incorporating an ultrafiltration recovery water tank and gate valves, can recover and store the regeneration flushing water, avoiding unnecessary water waste. The two gate valves allow for flexible control of the flushing water flow. Based on real-time monitoring data from online instruments, the system determines whether to recycle the flushing water or discharge it into a wastewater tank. This allows for flexible switching of the water flow direction according to specific water quality conditions and needs, ensuring efficient water use and compliant wastewater treatment.

[0024] The chemical wastewater tank is used to store and treat discharged wastewater. A control system using gate valves ensures that the wastewater undergoes proper treatment before entering the municipal sewer network, preventing the direct discharge of substandard wastewater and effectively controlling its environmental impact. Online instruments in the system monitor the ion exchanger's operating status in real time, providing real-time data support to automatically determine whether regeneration flushing water needs to be recycled or discharged. This automated water quality monitoring and control method reduces manual intervention, improves operational accuracy and efficiency, and further reduces costs. Attached Figure Description

[0031] See Figure 1-3 As shown, a reclaimed water treatment system includes:

[0032] Ion exchanger 1 is used for water treatment and to generate regeneration flushing water;

[0033] Ultrafiltration recovery water tank 2 is used to recover and store reusable water;

[0034] Chemical wastewater pond 3 is used for storing and treating discharged wastewater;

[0035] Two slide gate valves 4 are respectively located at:

[0036] The connection point between the ultrafiltration recovery water tank 2 and the chemical wastewater tank 3 ditch;

[0037] At the inlet of chemical wastewater tank 3, a device is used to control the switching of water flow direction;

[0038] Online instruments are used to monitor the operating data of ion exchanger 1 in real time and determine whether to recycle the regeneration flushing water or discharge it into the wastewater pool based on the data.

[0039] By recycling and storing the regenerated flushing water, the system can significantly reduce water waste. Most of the flushing water produced by ion exchanger 1 can be reused. Storing this water in the ultrafiltration recovery tank 2 effectively improves water resource utilization efficiency and reduces the demand for fresh water, which is especially important in water-scarce areas.

[0040] This system intelligently controls water flow direction and monitors water quality data in real time, ensuring that only water meeting reuse criteria is recycled, thus preventing the recycling of substandard water and reducing wastewater treatment and water procurement costs. Wastewater is only discharged to chemical wastewater pond 3 when needed, further reducing wastewater treatment costs and achieving operational cost savings for the company.

[0041] By recycling and reusing flushing water, the amount of wastewater discharged into the external environment is reduced. This not only helps reduce negative impacts on the ecological environment but also ensures that companies comply with regulatory emission standards, reducing pollutant emissions and contributing to the company's sustainable development goals.

[0042] The slide gate valve 4 includes a valve body 41 and a drive mechanism 42 for controlling the opening and closing of the valve body 41. The valve body 41 includes a slide plate 411, a slide plate channel 412 for accommodating the slide plate 411, a medium channel 413 disposed on both sides of the slide plate 411, and a sealing element disposed on the slide plate 411 for forming an effective seal between the slide plate 411 and the valve body 41.

[0043] The seals on the gate plate 411 ensure an effective seal between the gate plate 411 and the valve body 41, preventing media leakage. Good sealing performance helps improve system tightness, reduce media waste, avoid environmental pollution, ensure long-term stable system operation, and reduce maintenance and repair costs.

[0044] The slide gate valve 4 controls the opening and closing of the slide gate 411 via the drive mechanism 42, which can precisely regulate the flow rate of the medium. This precise control allows for flexible adjustment of the water flow direction as needed, achieving automated and intelligent management and improving system efficiency and response speed.

[0045] The slide gate valve 4 has a simple structure and is easy to operate, facilitating quick start-up and shutdown. Its design makes the disassembly, cleaning, and maintenance of the valve body 41 and slide gate 411 more convenient, reducing the incidence of equipment failure, extending service life, and reducing equipment maintenance time and costs.

[0046] The sealing element is located on both sides of the insert plate 411 and is inserted into the insert plate channel 412. The sealing element is a rubber sealing element. The medium channel 413 is a circular channel and is connected to the connection between the ultrafiltration recovery water tank 2 and the chemical wastewater tank 3 ditch and the pipe at the inlet of the chemical wastewater tank 3. The driving mechanism 42 includes a cylinder 421 for controlling the lifting and lowering of the insert plate 411, and a solenoid valve 422 located on one side of the cylinder 421 for controlling the driving of the cylinder 421.

[0047] Rubber seals are located on both sides of the insert plate 411 and snap into the insert plate channel 412, effectively preventing media leakage. The rubber material has good elasticity and sealing properties, maintaining a high sealing effect even after prolonged use, thereby improving the system's airtightness and stability, and reducing leakage risks and environmental pollution.

[0048] The media channel 413 is designed to be circular and connects to the connection point between the ultrafiltration recovery water tank 2 and the chemical wastewater tank 3, as well as the pipe at the inlet of the chemical wastewater tank 3, ensuring smooth water flow and accurate control. The direction of water flow can be precisely adjusted by switching the slide valve 4 on and off, ensuring the system can flexibly control the water flow according to needs, optimizing resource allocation and utilization.

[0049] The combination of cylinder 421 drive mechanism 42 and solenoid valve 422 enables the slide gate valve 4 to achieve automated control, reducing manual intervention and improving operating efficiency. Solenoid valve 422 controls the drive of cylinder 421, enabling rapid response to water flow control needs and making water flow switching more flexible and rapid. This reduces the workload of operators and improves the overall automation level and response speed of the system.

[0050] An upper sealing connector 414 and a lower sealing connector 423 are provided between the slide plate channel 412 and the cylinder 421. The upper sealing connector 414 and the lower sealing connector 423 are fixed together by bolts, and a sealing rubber ring is provided between the upper sealing connector 414 and the lower sealing connector 423. The cylinder 421 is a double-acting cylinder 421 that can drive the slide plate 411 to perform opening and closing operations in two directions. The solenoid valve 422 is a programmable solenoid valve 422 that can adjust the opening and closing state of the valve according to the real-time data of the online instrument.

[0051] The upper sealing connector 414 and the lower sealing connector 423 are fixed together with bolts and a sealing ring is provided to ensure a more reliable seal between the insert plate channel 412 and the cylinder 421. The sealing ring can effectively prevent media leakage, while the bolt fixing structure improves the stability of the connection, reduces loosening or leakage caused by vibration or external force, and enhances the safety and reliability of the equipment.

[0052] The double-acting cylinder 421 can drive the slide gate 411 in both directions to perform opening and closing operations, providing greater operational flexibility. This bidirectional drive design enables the slide gate valve 4 to respond quickly and achieve precise flow control, completing both opening and closing of the valve rapidly and stably, thus improving the valve's working efficiency and response speed.

[0053] The programmable solenoid valve 422 adjusts its on / off state based on real-time data from online instruments. This means that valve control can be dynamically adjusted according to the actual needs of the system, achieving intelligent management. This solution can automatically adjust the valve's state with the support of real-time monitoring data, eliminating the need for manual intervention, reducing operational errors, and improving the system's automation level and energy efficiency.
