Description

Technical Field

[0001] This utility model relates to the field of steam condensation recovery technology, specifically to a device for collecting and reusing steam condensate. Background Technology

[0002] In the existing steam condensate collection system, a simple collection measure is adopted, which requires adding a fire water tank pipeline for the condensate, and then adding a fire water supply pipeline for evaporative cooling from the fire water tank outlet pipeline. At the same time, a distillation water generator is required to obtain distilled water of good quality. This adds extra cost to the process. However, without adding a distillation water generator, it is not possible to obtain distilled water suitable for evaporative cooling, which will increase the risk of corrosion and scaling of the evaporative cooling tubes. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, this invention provides a device for collecting and reusing steam condensate, which solves the problem of not being able to obtain suitable distilled water for evaporation and cold water replenishment without adding a distilled water production device.

[0005] (II) Technical Solution

[0006] To solve the above problems, this utility model achieves the following technical solution: a device for collecting and reusing steam condensate, comprising: a flushing tank assembly, a conveying assembly internally connected to the flushing tank assembly, a fire water buffer tank disposed inside the flushing tank assembly, a buffer pipe fixedly connected to the inner wall above the fire water buffer tank, a collecting pipe fixedly connected to the outer wall of the buffer pipe outside the fire water buffer tank via a flange, and a level gauge threadedly connected to the inner wall of the fire water buffer tank above the buffer pipe on one side. The fire water buffer tank can temporarily store condensate, avoiding waste caused by direct discharge of condensate, and stabilizing the environment inside the tank; the buffer pipe can effectively slow down the speed at which condensate enters the fire water buffer tank, preventing splashing and noise caused by impact, and also avoiding large fluctuations in tank pressure due to impact; the collecting pipe can collect steam condensate from different sources, improving the collection efficiency of condensate; the level gauge can monitor the amount of condensate stored in the tank in real time, allowing staff to understand the situation inside the tank in a timely manner and avoiding problems such as overflow or insufficient condensate affecting subsequent use.

[0007] Preferably, the inner wall of the fire water buffer tank is fixedly connected to an inspection window, and the outer wall of the fire water buffer tank located on the side of the inspection window is fixedly connected to a PLC controller. A support column is fixedly connected to the bottom of the fire water buffer tank. The inspection window allows staff to easily observe the storage status of condensate inside the fire water buffer tank, the presence of impurities, and the operating status of internal components. When problems occur inside the tank, timely inspection and maintenance can be carried out through the inspection window, reducing the hassle of disassembling the tank and improving maintenance convenience. The PLC controller can monitor and control the operating parameters of each component in real time. Based on the electrical signals detected by the monitoring head, the electrical signals are transmitted to the level gauge through wires. The PLC controller adjusts the operating status of relevant components based on the level information fed back by the level gauge and adjusts the pressure based on the pressure information fed back by the temperature sensor, ensuring that the device is always in a stable and efficient operating state, reducing manual intervention and improving the automation level of the device. The support column provides stable support for the fire water buffer tank, preventing the tank from directly contacting the ground and causing corrosion or damage. At the same time, it keeps the tank at a suitable height, facilitating the operation and maintenance of relevant components at the bottom of the tank by staff, ensuring the long-term stable operation of the tank.

[0008] Preferably, the conveying assembly includes a pressure regulating valve, with connecting pipes fixedly connected to both the inlet and outlet of the pressure regulating valve. A temperature sensor is threadedly connected to the inner wall of the connecting pipe, and the monitoring head of the temperature sensor is located inside the connecting pipe. The pressure regulating valve can flexibly adjust the pressure during the condensate conveying process according to actual needs, avoiding damage or leakage to the conveying pipeline due to excessive pressure, or slow or obstructed condensate conveying speed due to excessive pressure, thus ensuring the stability and safety of the condensate conveying process. The connecting pipe provides an extension and connection for the condensate conveying channel, facilitating flexible adjustment of the conveying assembly layout according to the actual installation scenario and conveying path requirements, improving the flexibility and adaptability of the device assembly. The temperature sensor can monitor the temperature change of the condensate in the connecting pipe in real time and promptly feed the data back to the PLC controller, providing a reliable basis for pressure regulation, ensuring the timeliness of pressure regulation, and preventing the normal operation of the device from being affected by undetected pressure abnormalities, further improving the stability of the device operation. The pressure regulating valve is model PVZZYYP self-operated pressure regulating valve-B-20-P, and the temperature sensor is model WZPK-235.

[0009] Preferably, the monitoring end of the level gauge is located inside the lower part of the fire water buffer tank. A pump is connected to the end of the connecting pipe furthest from the temperature sensor, and a delivery pipe is connected to the outlet of the pump. The buffer pipe has a tortuous shape to buffer the condensate. The level gauge monitoring end, located inside the lower part of the fire water buffer tank, can comprehensively monitor the condensate level inside the tank, accurately capturing both high and low levels. This avoids excessive condensate residue in the tank due to undetected low levels, preventing waste or hindering subsequent cleaning, and also avoids condensate overflow due to undetected high levels, causing environmental pollution and resource waste. The pump provides power for the condensate delivery, allowing it to be transported through the connecting pipe to the delivery pipe, and then to... Designated reuse locations improve the efficiency of condensate delivery and meet the demand for condensate supply speed in the reuse process. The delivery pipe can transport condensate to designated reuse locations, realizing directional delivery of condensate and providing a reliable channel for condensate reuse. This ensures that the recovered condensate can be effectively used in subsequent production or other required processes, improving resource utilization. The tortuous structure of the buffer pipe effectively slows down the flow speed of condensate, avoiding the impact, splashing, and noise caused by condensate entering the fire water buffer tank at a high speed. It also prevents the pressure inside the tank from fluctuating drastically due to impact, ensuring the stability of the internal environment of the fire water buffer tank. The pump 23 is model BLC70 / 073.

This reduces the costs associated with distillation water preparation and evaporation cold water replenishment in industrial production, and improves resource utilization efficiency and production economy.

[0013] (ii) The device for collecting and reusing steam condensate can be used as distilled water for evaporative cooling water replenishment.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution for a collection and reuse device for steam condensate, comprising: a flushing tank assembly 1, a conveying assembly 2 internally connected to the flushing tank assembly 1, a fire water buffer tank 11 inside the flushing tank assembly 1, a buffer pipe 13 fixedly connected to the inner wall above the fire water buffer tank 11, a collection pipe 14 fixedly connected to the outer wall of the buffer pipe 13 outside the fire water buffer tank 11 via a flange, a level gauge 12 threadedly connected to the inner wall of the fire water buffer tank 11 above the buffer pipe 13, an inspection window 4 fixedly connected to the inner wall of the fire water buffer tank 11, a PLC controller 3 fixedly connected to the outer wall of the fire water buffer tank 11 beside the inspection window 4, and a support column fixedly connected to the bottom of the fire water buffer tank 11.

[0021] The conveying assembly 2 includes a pressure regulating valve 21, and both the inlet and outlet of the pressure regulating valve 21 are fixedly connected to a connecting pipe 22. A temperature sensor 25 is threadedly connected to the inner wall of the connecting pipe 22, and the monitoring head of the temperature sensor 25 is located inside the connecting pipe 22.

[0022] The monitoring end of the level gauge 12 is located inside the lower part of the fire water buffer tank 11. The end of the connecting pipe 22 away from the temperature sensor 25 is connected to the pump 23. The outlet of the pump 23 is connected to the delivery pipe 24. The buffer pipe 13 has a tortuous shape to buffer the condensate.

[0023] In use, steam condensate from various stages of industrial production is collected through a pre-set collection pipe 14. Since the collection pipe 14 is fixedly connected to the buffer pipe 13 via a flange, and the buffer pipe 13 has a tortuous structure, the condensate first flows into the buffer pipe 13. Due to the tortuous nature of the buffer pipe 13, the speed of the condensate is effectively slowed down during the flow process, preventing the high-speed flowing condensate from directly impacting the subsequent storage structure. At the same time, it reduces the splashing and noise caused by the impact. After being buffered, the condensate flows smoothly into the fire water buffer tank 11 through the connection structure between the buffer pipe 13 and the fire water buffer tank 11. The fire water buffer tank 11, as the core storage component, temporarily stores the condensate, providing a stable liquid source for the subsequent transportation process. Moreover, the fire water buffer tank 11 is located inside the flushing assembly 1, which provides it with a stable installation and protection environment, ensuring the safety of the storage process.

[0024] Secondly, there is the real-time monitoring of the condensate storage status. During the operation of the fire water buffer tank 11, the level gauge 12 installed on one side of the upper buffer pipe 13 inside it works continuously. The monitoring end of the level gauge 12 is located inside the lower part of the fire water buffer tank 11, which can fully cover the liquid level range of the condensate in the tank. It can monitor the higher liquid level to prevent overflow, and it can also monitor the lower liquid level to avoid excessive liquid residue in the tank or interruption of the liquid supply during transportation. At the same time, the PLC controller 3 on the outer wall of the fire water buffer tank 11 receives the liquid level data transmitted by the level gauge 12 in real time, forming a dynamic monitoring of the condensate storage in the tank, providing a basis for the start-up, shutdown and adjustment of the subsequent transportation process. In addition, the inspection window 4 on the inner wall of the fire water buffer tank 11 allows the staff to observe the condensate status in the tank and whether the components are normal during the intervals between device operation, which helps to ensure the stability of the storage process.

[0025] Finally, there is the stable delivery of condensate. When the PLC controller 3 determines, based on the data from the level gauge 12, that the condensate in the fire water buffer tank 11 has reached the deliverable amount, it will activate the delivery assembly 2 to deliver the condensate. In the delivery assembly 2, the connecting pipe 22, which is connected to the fire water buffer tank 11, serves as the delivery channel. A pump 23 is connected to the end of the connecting pipe 22 furthest from the temperature sensor 25. After the pump 23 starts, it generates power to draw the condensate from the fire water buffer tank 11 into the connecting pipe 22. As the condensate flows through the connecting pipe 22, the temperature sensor 25, whose monitoring head is located inside the pipe, monitors the temperature of the condensate in real time. The temperature sensor 25 detects that the temperature is too high or too low, and transmits the data of the temperature change to the PLC controller 3. If the temperature sensor 25 detects that the temperature is too high or too low, the PLC controller 3 will immediately send a control signal to the pressure regulating valve 21. The pressure regulating valve 21 is installed between the connecting pipes 22 and can change the flow resistance of the condensate through its own adjustment function, thereby stabilizing the pressure in the connecting pipe 22 within a suitable range and avoiding abnormal pressure that could lead to pipeline leakage or poor transport. After pressure regulation, the condensate is finally transported to the reuse stage required for industrial production through the delivery pipe 24 that is connected to the outlet of the pump 23, thus completing the closed loop of steam condensate recovery and reuse.

[0026] Throughout the process, the support column below the fire water buffer tank 11 always provides stable support for the tank body, ensuring that each link operates in a stable installation environment; the PLC controller 3, as the core control component, integrates monitoring data such as liquid level and pressure to realize the regulation of the conveying component 2, so that each link of the device works together to ultimately achieve the purpose of steam condensate recovery and reuse, and to obtain distilled water suitable for evaporative cooling water replenishment without adding a distilled water production device, thus avoiding the risk of corrosion and scaling of the evaporative cooling tubes.
