Abstract
Description
Technical Field
[0001] This utility model relates to the field of condensate recovery technology, and in particular to a condensate recovery conductivity detection system. Background Technology
[0002] During condensate recovery, the long pipelines passing through storage tanks, pipes, containers, valves, and other components inevitably subject the pipelines to acid and oxygen corrosion, resulting in condensate with excessive conductivity. Condensate with excessive conductivity flowing back into the boiler accelerates corrosion within the boiler furnace, affecting not only the heat transfer efficiency of the furnace tubes but also posing a risk of tube rupture. To prevent boiler damage and contamination, the conductivity of the recovered condensate must be tested to ensure that the condensate entering the boiler meets its operational safety standards.
[0003] In traditional technology, the conductivity of condensate can be measured by installing a conductivity meter on the condensate recovery pipeline. The results of the conductivity meter are used to determine whether the condensate meets the standards. However, the accuracy of the conductivity meter measurement cannot be confirmed, which requires improvement and optimization. Utility Model Content

[0031] Figure 1 This schematic diagram illustrates the structure of a condensate recovery conductivity detection system according to one embodiment of the present invention, as shown below. Figure 1 As shown, the present invention provides a condensate recovery conductivity detection system, comprising:
[0032] The system includes a recovery pipeline 10, a detection pipeline 20, a first discharge pipeline 30, a calibration pipeline 40, and a control module 50.
[0033] Both ends of the detection pipeline 20 are connected to the recovery pipeline 10, one end of the first discharge pipeline 30 is connected to the recovery pipeline 10 and is located between the end of the recovery pipeline 10 and the detection pipeline 20, the calibration pipeline 40 is connected to the detection pipeline 20, and the control module 50 is connected to the recovery pipeline 10, the detection pipeline 20 and the first discharge pipeline 30 respectively.
[0034] The recovery pipeline 10 is used for the recovery of qualified condensate, the first discharge pipeline 30 is used for the discharge of unqualified condensate, the detection pipeline 20 is used for detecting the conductivity value of condensate, the calibration pipeline 40 is used for calibration of the detection pipeline 20 before detection, and the control module 50 is used to receive the condensate conductivity information detected by the detection pipeline 20 and control the opening and closing of the recovery pipeline 10 and the first discharge pipeline 30 according to the condensate conductivity information.
[0035] Specifically, before testing, standard sample water is introduced into the testing pipeline 20 through the calibration pipeline 40. The test value is detected through the testing pipeline 20 and sent to the control module 50. The control module 50 displays the conductivity value of the standard sample water for the user to view. The user compares the conductivity value of the standard sample water with the actual conductivity value to determine whether the test pipeline 20 is accurate. If it is inaccurate, the testing pipeline 20 is calibrated. If it is accurate, condensate water is introduced from the beginning of the recovery pipeline 10. After the condensate water enters the testing pipeline 20 to complete the test, the control module 50 controls the downstream position of the recovery pipeline 10 and the opening and closing of the first discharge pipeline 30 according to the test results. When the test is qualified, the first discharge pipeline 30 is disconnected and the recovery pipeline 10 is connected to transport the qualified condensate water to the next process. If the test is unqualified, the port of the recovery pipeline 10 is controlled and the first discharge pipeline 30 is connected to discharge the unqualified condensate water.
[0036] This setup, through the calibration pipe 40, ensures the accuracy of the detection pipe 20, avoids damage to the boiler from substandard condensate, and ensures the safe operation of the boiler. At the same time, when the detection pipe 20 is restarted after a long period of inactivity, standard sample water can be introduced through the calibration pipe 40 to flush the detection pipe 20 and the equipment on it, ensuring a clean detection environment for the detection pipe 20 and further improving the accuracy of the detection.
[0037] Furthermore, by connecting the existing condensate recovery system to the parallel detection pipeline, there is no need to make major changes to its layout. The overall system structure is compact, easy to install, and fully functional, which can ensure that the condensate recovery system achieves maximum energy-saving benefits, thereby reducing energy costs and carbon emissions.
[0038] Furthermore, a first electric ball valve 101 is provided on the recovery pipeline 10, the first electric ball valve 101 is located between the first discharge pipeline 30 and the end of the recovery pipeline 10, a second electric ball valve 301 is provided on the first discharge pipeline 30, and a conductivity sensor 201 is provided on the detection pipeline 20.
[0039] The conductivity sensor 201 is used to detect the conductivity value of the condensate. The first electric ball valve 101, the second electric ball valve 301 and the conductivity sensor 201 are respectively connected to the control module 50. When the conductivity sensor 201 detects a value, it sends it to the control module 50. The control module 50 receives the value and controls the opening and closing of the first electric ball valve 101 and the second electric ball valve 301 according to the value, so as to realize the recovery of qualified condensate and the discharge of unqualified condensate.
[0040] Specifically, a standard value is preset in the control module 50. When the control module 50 receives the detection value sent by the conductivity sensor 201, it compares it with the preset standard value. If the detection value is less than the standard value, the condensate is deemed qualified. At this time, the first electric ball valve 101 is opened and the second electric ball valve 301 is closed to realize the recovery of qualified condensate. If the detection value is greater than the standard value, the condensate is deemed unqualified. At this time, the first electric ball valve 101 is closed and the second electric ball valve 301 is opened to realize the discharge of unqualified condensate and realize automated control.
[0041] Furthermore, the control module 50 is equipped with a human-machine interface, which can display the real-time and past detection values of the conductivity sensor 201, as well as the real-time and past control flow of the overall system. Users can also manually control and adjust preset standard values on it.
[0042] Furthermore, a check valve 102 is provided on the recovery pipeline 10. The check valve 102 is located between the two ends of the detection pipeline 20. The check valve 102 is used to prevent the condensate in the detection pipeline 20 from flowing back to the left when it flows to the recovery pipeline 10.
[0043] Furthermore, a second discharge pipe 60 is connected to the detection pipe 20. Along the direction of condensate flow, the calibration pipe 40 is connected upstream between the conductivity sensor 201 of the detection pipe 20 and the recovery pipe 10, and the second discharge pipe 60 is connected downstream between the conductivity sensor 201 of the detection pipe 20 and the recovery pipe 10. The second discharge pipe 60 is used to discharge the standard water provided by the calibration pipe 40.
[0044] Furthermore, a first ball valve 601 is installed on the second discharge pipeline 60. When used to discharge standard sample water, the first ball valve 601 is controlled to open and close to achieve discharge. When used to detect condensate, the first ball valve 601 is controlled to close to ensure normal flow of condensate.
[0045] Furthermore, a second ball valve 202 is installed on the detection line 20 between the calibration line 40 and the recovery line 10, and a third ball valve 203 is installed on the detection line 20 between the second discharge line 60 and the recovery line 10. When standard sample water is introduced into the calibration line 40, the second ball valve 202 and the third ball valve 203 are controlled to be disconnected to ensure that the standard sample water does not flow into the recovery line 10. When condensate is introduced into the recovery line 10, the second ball valve 202 and the third ball valve 203 are controlled to be opened to ensure that the condensate can enter the detection line 20 and flow out of the detection line 20.
[0046] Furthermore, a fourth ball valve 401 is installed on the calibration pipeline 40. The fourth ball valve 401 can control the opening and closing of the calibration pipeline 40 to realize the supply and isolation of standard sample water.
[0047] Furthermore, the diameters of the recovery pipe 10 and the first discharge pipe 30 are 80 mm, while the diameters of the calibration pipe 40, the detection pipe 20, and the second discharge pipe 60 are 32 mm. The larger pipe diameters can appropriately increase the condensate flow rate and volume, thereby increasing the overall system's recovery and discharge efficiency. Conversely, the smaller pipe diameters can appropriately reduce the condensate flow rate and volume, ensuring that the conductivity sensor 201 has more detection time and that the detection pipe 20 is thoroughly flushed.
[0048] In summary, the condensate recovery conductivity detection system provided by this utility model does not require any changes to the layout of existing condensate recovery systems. It only requires connecting the detection pipeline 20 in parallel to the recovery pipeline 10 and equipping it with corresponding pipes, detection instruments, and valve accessories. This ensures that all qualified condensate is recovered and that unqualified condensate cannot flow back to the boiler. The overall system has a compact structure, is easy to install, and has complete functions. It can ensure that the condensate recovery system achieves maximum energy-saving benefits, reduce energy costs, reduce carbon emissions, and ensure the safe operation of the boiler.
