Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, specifically a remote visual brine concentration monitoring device and a steam injection boiler water treatment system. Background Technology

[0002] The core module of the feedwater treatment device for oilfield steam injection boilers is a sodium ion exchanger, which is used for softening (hardness removal) of raw water, that is, removing calcium and magnesium ions in the water that can form hardness and preventing scale formation on boiler tubes.

[0003] Sodium ion exchangers typically consist of two sets: one in operation and the other in "regeneration" standby, operating alternately. "Regeneration" involves passing a dilute brine (8-12%) through the resin bed to react with the resin particles that have lost their exchange capacity, restoring their water treatment ability. This process mainly involves three steps: coarse salt dissolution, introducing dilute brine, and replacement cleaning. Therefore, it is necessary to monitor three types of brine concentrations: the concentrated brine concentration in the brine tank, the concentration of the diluted brine, and the residual brine concentration after replacement cleaning.

[0004] Current online brine concentration detection devices can only measure clean brine, not industrial crude brine. Industrial crude brine contains many impurities, mainly silt and other metal ions, leading to inaccurate measurement signals. These signals cannot accurately reflect the brine concentration at each step of the regeneration process, affecting the regeneration efficiency of the sodium ion exchanger and reducing water production; at the same time, salt consumption is high.

[0005] However, when using a hydrometer that can detect industrial crude salt water, the industrial crude salt impurities can contaminate the water storage pipe, affecting the reading of the hydrometer's information.

[0006] Publication No. CN108195716A discloses an online saline concentration detection device and method, including a vertically arranged water storage tank with an inlet at the lower end and an outlet at the upper end. Both the inlet and outlet are connected to the saline concentration detection device. The device continuously monitors the pressure of the saline at the inlet and outlet, calculates the saline density based on the pressure difference, and then determines the saline concentration by analyzing the relationship between the density and concentration, thus achieving real-time detection.

[0007] This existing technology is not suitable for detecting the concentration of crude brine with a high amount of impurities.

[0008] Publication No. CN110530759A discloses an automatic liquid concentration measurement system based on a Baumé hydrometer, including a liquid level differential meter, a controller, a float, a housing, and a temperature sensor. The float is fixed at the upper opening of the housing, and a hydrometer is installed on the float. The liquid level differential meter includes two ultrasonic ranging probes, which are mounted on a support rod above the float. The detection direction of the ultrasonic ranging probes is perpendicular to the float, and one of the detection directions is along the axis of the hydrometer. Both the liquid level differential meter and the temperature sensor are connected to the controller.

[0009] The existing technology has many external parts and requires high assembly precision, making it unsuitable for use in water treatment systems for steam injection boilers operating in harsh environments.

[0010] Publication No. CN104568655A discloses an automatic liquid concentration measurement method, comprising: a microcontroller, a camera, a buoyancy meter, a temperature sensor, a solenoid valve, a sampling pump, measurement software, and an LCD screen. The microcontroller is connected to the camera, temperature sensor, LCD screen, and solenoid valve. The camera, connected to the microcontroller, is used to acquire image signals from the buoyancy meter; the temperature sensor, connected to the microcontroller's input terminal, is used to detect the liquid temperature in real time; the solenoid valve, connected to the microcontroller, is used to switch between the liquid to be measured and the cleaning water; the sampling pump, connected to the microcontroller, is used to pump the liquid into a sample cell. The microcontroller and camera acquire images from the buoyancy meter, calculate the position of the buoyancy meter in the image to obtain the solution concentration information, simultaneously acquire the solution temperature, perform temperature correction on the concentration, and display the results on the LCD screen.

[0011] The existing technology suffers from the problem of coarse salt impurities contaminating the inner wall of the sample cell, making it impossible for the camera to clearly read the position of the buoyancy meter.

[0012] In summary, the technical solutions, technical problems to be solved, and beneficial effects of the above-disclosed technologies are all different from those of this utility model. For more technical features, technical problems to be solved, and beneficial effects of this utility model, the above-disclosed technical documents do not provide any technical inspiration.

The camera 2 can be adjusted remotely.

[0063] The inner wall of the water storage pipe 1.1.2 is cleaned by the measuring tube cleaning assembly 1.3, so that the camera 2 can observe the scale 1.2.3 of the salt water hydrometer 1.2.

[0064] Example 2:

[0065] Based on Example 1, this example provides a steam injection boiler water treatment system, including a sodium ion exchanger, a brine tank 3, a raw water tank 14, a drain tank 24, and a remote visual brine concentration monitoring device as described in Example 1.

[0071] Specifically, two or more sodium ion exchangers may be provided.

[0072] Sodium ion exchanger is installed in the primary tank 19 and the secondary tank 20.

[0073] Among them, the brine circulation valve 5, the first control valve 16, the second control valve 17, the flow valve 18, the third control valve 21, the fourth control valve 22, and the fifth control valve 23 are solenoid valves, and the brine dilution valve 13 is an electric flow regulating valve.

[0074] Example 3:

[0075] Based on Example 2, this example provides a method for using a steam injection boiler brine regeneration water treatment system, including the following steps:

[0076] S1, softened water supply status: Open the first control valve 16, the second control valve 17, the process valve 18, and start the raw water pump 15. The raw water passes through the water supply pipeline, the primary tank 19, the liquid delivery pipeline, the secondary tank 20, and the outlet pipeline. The raw water undergoes two stages of softening to remove calcium and magnesium ions from the raw water, providing the steam injection boiler 25 with high-quality and sufficient softened water to prevent scale formation on the boiler tubes.

[0077] S2. The two sodium ion exchangers are group A and group B, respectively. Group B supplies softened water, while group A enters the regenerated brine working state.

[0078] Monitor the concentration of concentrated saline solution (≥12%):

[0079] Group A sodium ion exchangers are in the salt inlet state. First, concentrated brine is prepared. The programmer starts brine pump 4, and at the same time, brine circulation valve 5 opens. Brine enters the middle of brine tank 3 from the brine tank 3 along the circulation pipeline. Simultaneously, concentrated brine switching valve 6 opens, and brine enters the measuring component 1 along the concentrated brine pipeline and the brine inlet hose 12. The brine hydrometer 1.2 begins to rise. Camera 2 observes the brine percentage concentration scale 1.2.3 and transmits the video image back to the central control room. The operator monitors the video image. If the brine concentration is less than 8%, the industrial coarse salt in the brine tank 3 continues to circulate and dissolve. When the brine concentration is greater than 12%, brine pump 4, brine circulation valve 5, and concentrated brine switching valve 6 are stopped. At this time, the concentrated brine has been prepared.

[0080] Monitor the concentration of dilute saline solution (≥8%, ≤12%):

[0081] After the concentrated brine is prepared, the sodium ion exchanger in Group A begins to regenerate and feed dilute brine. The programmer starts the brine pump 4, and the third control valve 21, the fourth control valve 22, and the fifth control valve 23 are opened. The brine enters the secondary tank 20, then enters the primary tank 19 of the sodium ion exchanger through the top pipeline, and flows into the drainage tank 24 through the drainage pipeline.

[0082] Simultaneously, the brine dilution valve 13 opens, allowing softened water from the sodium ion exchanger in group B to enter the brine pipeline for dilution. At the same time, the dilute brine switching valve 7 opens, and brine flows along the dilute brine pipeline and the brine inlet hose 12 into the measuring component 1. The brine hydrometer 1.2 starts operating, and the camera 2 observes the brine percentage concentration scale 1.2.3, transmitting the video image back to the central control room. The operator monitors the video image. If the brine concentration is not ≥8% or ≤12%, the opening of the brine dilution valve 13 is adjusted until the dilute brine concentration reaches the range of ≥8% or ≤12%. When the set brine inlet time is approached, the dilute brine switching valve 7 is closed, and the residual brine switching valve 8 is opened to measure the brine concentration in the drainage pipeline. When the residual brine concentration approaches 8%, the brine inlet ends, and the brine pump 4 is remotely shut down, closing all valves in the brine inlet process.

[0083] The sodium ion exchanger in Group A has entered the "sedimentation" stage of regeneration.

[0084] Monitor residual saline concentration (≤2%):

[0085] After the set time for the regeneration of the sodium ion exchanger in Group A to enter the "sedimentation" stage, the regeneration of the sodium ion exchanger in Group A begins the softened water replacement and cleaning stage. The programmer fully opens the brine dilution valve 13, and the third control valve 21, the fourth control valve 22, and the fifth control valve 23, allowing the softened water from the sodium ion exchanger in Group B to enter the secondary tank 20 of the sodium ion exchanger in Group A, and then enters the primary tank 19 of the sodium ion exchanger through the top pipeline, flowing into the drain tank 24 along the drain pipeline. At the same time, the residual brine switching valve 8 opens, and the softened water containing residual brine enters the measuring component 1 through the brine inlet hose 12. The brine specific gravity meter 1.2 begins to decrease, and the camera 2 observes the brine percentage concentration scale 1.2.3, transmitting the video image back to the central control room. The operator monitors the video image until the residual brine concentration is ≤2%, at which point the cleaning is completed, and all valves in the cleaning process are remotely closed.

[0086] During the regeneration process, manually adjust the flow regulating valve 10 on the brine pipeline to regulate the amount of brine entering the measuring component 1, ensuring a uniform flow rate that matches the overflow pipe 1.1.3.
