Description

Technical Field

[0001] This invention belongs to the field of water-rock reaction monitoring technology, specifically relating to a water-rock reaction monitoring device and monitoring method. Background Technology

[0002] Currently, water-rock reaction refers to a series of physicochemical reactions that occur between groundwater and surrounding rock minerals. Under different temperature conditions, water-rock reaction can change the pore structure, mineral composition, and fluid properties of rocks.

[0003] The commonly used monitoring methods for water-rock reactions are fluid chemical monitoring and physical property monitoring. However, these two methods provide limited experimental data and can only provide indirect information, failing to determine specific chemical changes. Spectroscopic visualization monitoring can quantitatively analyze the concentration of target samples without contact, but this method is complex to operate and expensive. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a monitoring device and method for water-rock reaction.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a monitoring device for water-rock reaction, comprising a base two, a reaction vessel mounted on the top of the base two, multiple heating tubes installed inside the reaction vessel, each of the multiple heating tubes being externally connected to a heating power supply, multiple monitoring through holes opened on the side of the reaction vessel, a capillary tube placed inside the multiple monitoring through holes, water-rock material placed inside the capillary tube, an optical fiber Raman probe placed inside the capillary tube, a sealing ring provided between the end of the capillary tube and the wire portion of the optical fiber Raman probe, a temperature sensor installed inside the multiple monitoring through holes, and a data acquisition mechanism detachably connected to the end of the optical fiber Raman probe away from the capillary tube.

[0006] Preferably, the data acquisition mechanism includes an optical switching switch and a back-collecting Raman module. The end of the fiber Raman probe away from the capillary is detachably connected to the optical switching switch. The optical switching switch and the back-collecting Raman module are electrically connected via a wire. The back-collecting Raman module is electrically connected to a laser via a wire. The back-collecting Raman module is electrically connected to a spectrometer via a wire. A CCD is disposed on the outside of the spectrometer.

[0007] Preferably, a base one is mounted on the side of the base two, a side U-shaped frame is mounted on the top of the base one, a lifting mechanism is mounted on the top of the side U-shaped frame, a moving mechanism is mounted on the side of the lifting mechanism, a clamping mechanism is mounted on the side of the moving mechanism, and the capillary tube is placed in the clamping mechanism.

[0008] Preferably, the lifting mechanism includes a guide rail and a servo motor. The guide rail is installed above the side U-shaped frame, and the servo motor is installed above the guide rail. The output end of the servo motor is detachably connected to a trapezoidal lead screw, and a slider is fitted on the trapezoidal lead screw. The slider is slidably connected to the guide rail, and the moving mechanism is installed on the side of the slider.

[0009] Preferably, the moving mechanism includes an electric push rod and a second connecting plate. The electric push rod is installed on the side of the slider, the second connecting plate is installed at the piston rod end of the electric push rod, and connecting blocks are installed at both ends of the second connecting plate. The clamping mechanism is installed between the two connecting blocks, and a third connecting plate is installed between the second connecting plate and the clamping mechanism.

[0010] Preferably, the clamping mechanism includes a connecting plate and two support plates. The side of the connecting plate is fixedly connected to the second connecting plate. The two support plates are respectively installed between the connecting plate and the connecting block. A bidirectional lead screw passes through the two support plates. Two sliding blocks are fitted on the bidirectional lead screw. Arc-shaped clamping blocks are installed on the side of the two sliding blocks away from the support plates. The capillary tube is located between the two arc-shaped clamping blocks. A servo motor is detachably connected to the end of the bidirectional lead screw. A sliding groove is opened on the side of the connecting plate at the position corresponding to the sliding block. The sliding groove is slidably connected to the sliding block.

[0011] Preferably, each of the monitoring through holes has a frustum hole on its side, the frustum hole being connected to the monitoring through hole, and a plug being placed inside the frustum hole.

[0012] Preferably, a support column 1 and a support column 2 are installed between the side U-shaped frames. A horizontal plate 1 is installed on the side of the support column 1 near the reactor. Multiple support columns 3 are installed between the horizontal plate 1 and the base 2. The reactor is located between the base 2 and the horizontal plate 1.

[0013] Preferably, the lifting mechanism is externally connected to a controller, and both the moving mechanism and the clamping mechanism are communicatively connected to the controller.

[0014] A method for monitoring water-rock reaction, using the aforementioned water-rock reaction monitoring device, includes the following steps: Step 1: Place the water-rock material to be tested inside the capillary tube, then insert the fiber Raman probe into the capillary tube containing the water-rock material, and place a sealing ring between the end of the capillary tube and the wire part of the fiber Raman probe. Step 2: Place the packaged capillary tube into the monitoring through hole opened on the side of the reactor, and electrically connect the end of the fiber Raman probe away from the capillary tube to the data acquisition mechanism. Step 3: Turn on the external heating power supply to the multiple heating tubes inside the reactor to start heating the capillary tube; Step 4: The water-rock reaction begins inside the capillary, and the data is transmitted to the data acquisition mechanism via an optical fiber Raman probe; Step 5: After monitoring is completed, disconnect the data acquisition mechanism from the fiber Raman probe, remove the capillary tube from the monitoring through hole, and analyze the acquired data.

[0015] Compared with the prior art, the advantages and positive effects of the present invention are as follows: (1) Existing fluid chemical monitoring and physical property monitoring can only provide indirect information. However, this invention directly places an optical fiber Raman probe inside the capillary and utilizes the high sensitivity of Raman spectroscopy to molecular structure and chemical bonds to directly capture the evolution characteristics of material composition, phase state and molecular structure during the water-rock reaction process, providing rich and intuitive direct experimental data. (2) Existing spectral visualization monitoring methods are complicated to operate, while the present invention has a lifting mechanism installed above the side U-shaped frame, a moving mechanism installed on the side of the lifting mechanism, and a clamping mechanism installed on the side of the moving mechanism. The capillary is placed in the clamping mechanism. The lifting mechanism, the moving mechanism and the clamping mechanism can automate the entire monitoring process, reducing the complexity of manual operation and experimental errors. (3) Place the water-rock material and fiber Raman probe in the capillary tube, then put the capillary tube into the monitoring through hole, and heat the capillary tube. Due to the small volume inside the capillary tube, the temperature is easier to control, reducing the occurrence of dangerous situations. As a result, the heating tube heats the capillary tube more evenly. (4) The end of the fiber Raman probe away from the capillary can be detachably connected to an optical switching switch. Only one spectral acquisition system is needed, that is, the optical switching switch can be used to switch and monitor between multiple capillary channels.

[0016] (5) The present invention realizes the position adjustment of the capillary tube through the lifting mechanism, the moving mechanism and the clamping mechanism, avoiding the problem of capillary tube breakage caused by manual operation and improving the safety of the experiment; (6) The monitoring through hole of the reactor is provided with a frustum hole with a smaller inner diameter and a larger outer diameter. The outer diameter of the arc-shaped clamping block in the clamping mechanism is larger than the large diameter of the frustum hole. After the capillary is pushed into the monitoring through hole, the arc-shaped clamping block can fit and seal the opening of the frustum hole, which plays a role in heat insulation and sealing during the reaction. When there is no capillary or the capillary is removed after monitoring, the rapid loss of heat caused by air convection can be completely prevented by placing a plug in the frustum hole, thus ensuring the stability and uniformity of the internal temperature field of the reactor.

[0030] In this invention, the heating tube is located between adjacent monitoring through holes, and the heating tube is not connected to the monitoring through holes.

[0031] In this invention, the guide rail 10 is vertically mounted above the side U-shaped frame 2.

[0032] In this invention, a plug needs to be placed in the frustum hole 16 corresponding to the monitoring through hole where the capillary tube 8 is not placed. The plug can prevent temperature loss due to air convection.

[0033] In this invention, the small diameter of the frustum hole 16 is close to the monitoring through hole.

[0034] In this invention, rubber pads are installed on the sides of the two arc-shaped clamping blocks 17 near the capillary tube 8.

[0035] In this invention, connecting plates four are installed on the sides of both arc-shaped clamping blocks 17. Multiple through holes one are opened on the top of the connecting plates four. Bolts are placed in the through holes one of the connecting plates four on the same side. The bolts can further fix the capillary tube 8.

[0036] In this invention, the outer diameter of the arc-shaped clamping block 17 is larger than the large diameter of the frustum hole 16.

[0037] In this invention, the lifting mechanism is externally connected to a controller, and the moving mechanism and the clamping mechanism are both communicatively connected to the controller.

[0038] In this invention, the temperature sensor, servo motor 11, electric push rod 9, and servo motor 20 are all connected to the controller.

[0039] A method for monitoring water-rock reaction includes the following steps: Step 1: Place the water-rock material to be tested inside the capillary tube 8, and then insert the fiber Raman probe 26 into the capillary tube 8 containing the water-rock material. Place a sealing ring between the end of the capillary tube 8 and the wire portion of the fiber Raman probe 26. Step 2: Place the packaged capillary tube 8 into the monitoring through hole on the side of the reactor 7, and electrically connect the end of the fiber Raman probe 26 away from the capillary tube 8 to the data acquisition mechanism. Step 3: Turn on the external heating power supply to the multiple heating tubes inside the reactor 7 to start heating the capillary tube 8; Step 4: The water-rock reaction begins inside capillary 8, and the data is transmitted to the data acquisition mechanism through fiber optic Raman probe 26; Step 5: After monitoring is completed, disconnect the data acquisition mechanism from the fiber Raman probe 26, remove the capillary tube 8 from the monitoring through hole, and analyze the acquired data.

[0040] In this invention, step one includes: placing the water-rock material to be tested inside the capillary tube 8, then inserting the detection end of the fiber Raman probe 26 into the capillary tube 8 containing the water-rock material, so that the detection end of the fiber Raman probe 26 is located inside the water-rock material, and finally fitting a sealing ring between the end of the capillary tube 8 and the wire portion of the fiber Raman probe 26 and pressing it tightly to ensure that a closed reaction space is formed inside the capillary tube 8.

[0041] In this invention, step two includes: placing the packaged capillary tube 8 horizontally between two arc-shaped clamping blocks 17 of the clamping mechanism; turning on the second servo motor 20, which drives the bidirectional lead screw 19 to rotate, causing the two sliding blocks 18 to move towards the capillary tube 8 until the arc-shaped clamping blocks 17 jointly clamp the capillary tube 8; turning off the second servo motor 20; turning on the first servo motor 11, which drives the trapezoidal lead screw 13 to rotate, causing the slider 12 to move along the guide rail 10, aligning the axis of the capillary tube 8 with the axis of the monitoring through hole; turning off the first servo motor 11; and turning on the electric push rod 9, which pushes the capillary tube 8 towards the reaction vessel 7, i.e., the capillary tube 8... The arc-shaped clamping block 17 enters the monitoring through hole, and the side of the arc-shaped clamping block 17 near the reactor 7 abuts against and seals the opening of the frustum hole 16 outside the monitoring through hole. The servo motor 11 is turned off, and the servo motor 20 is turned on, so that the arc-shaped clamping block 17 is disengaged from the capillary tube 8. The servo motor 20 is turned off, and the electric push rod 9 is turned on, so that the arc-shaped clamping block 17 returns to the initial position. The end of the fiber Raman probe 26 in the capillary tube 8 is electrically connected to the optical switching switch 14 of the data acquisition mechanism. At this time, a complete data and optical path is formed between the fiber Raman probe 26, the optical switching switch 14, the back-collecting Raman module 27, the laser 28, the spectrometer 29, and the CCD 30.

[0042] In this invention, step three includes: monitoring the temperature inside the monitoring through hole of the reactor 7 by means of a temperature sensor installed inside the monitoring through hole, thereby turning on the heating power supply to heat the capillary tube 8 of the monitoring through hole to the monitoring temperature, and determining whether the monitoring temperature has been reached by means of the temperature sensor.

[0043] In this invention, step four includes: starting the laser 28 to emit an excitation laser, transmitting the laser to the back-collecting Raman module 27 via wire two, switching the optical switch 14 to the currently tested capillary 8 channel, and irradiating the water-rock material inside the capillary 8 via the optical switch 14 and the fiber Raman probe 26. The excited Raman scattered light returns along the original path, is collected by the fiber Raman probe 26, and is transmitted back to the back-collecting Raman module 27 via the optical switch 14. The back-collecting Raman module 27 transmits the collected Raman light signal to the spectrometer 29 via wire three for processing. The processed spectral signal is imaged and recorded by the CCD 30 set on the outside of the spectrometer 29, recording the Raman spectral characteristic data of the material composition, molecular structure, and phase evolution over time during the water-rock reaction.

[0044] In this invention, step five includes: after monitoring is completed, the optical switching switch 14 is disconnected from the fiber Raman probe 26, the experimenter removes the capillary tube 8, and promptly places a plug in the corresponding empty monitoring through hole 16 so that the residual heat in the reactor 7 can be quickly dissipated due to air convection. The time-series Raman spectral data collected by the CCD 30 and spectrometer 29 during the entire reaction process are exported. Combined with the temperature history curve of the temperature sensor in the reactor 7, the peak intensity, peak position and half width at half maximum of the spectrum are qualitatively and quantitatively analyzed to obtain the reaction evolution law of the water-rock material.

[0045] In this invention, the above process can be automatically controlled by a controller.

[0046] In this invention, the above process can be adjusted according to the on-site conditions.

[0047] As a technical solution of this invention, the provided hardware configuration is merely for facilitating the implementation of specific braking control based on the hardware facilities. How to specifically implement braking control and the braking control method are not the technical problems to be solved or the objects of protection of this invention. Furthermore, the communication methods between the devices all employ existing communication methods and are not the inventive point of this invention.
