A smart spill-proof in-situ repair reagent injection control system

Abstract

This invention provides an intelligent spill-proof in-situ remediation reagent injection control system, belonging to the field of soil remediation technology. It includes a main frame, a reagent injection assembly mounted on the main frame, an intelligent control module, an early warning and emergency response module, and a parameter monitoring module. A variable-speed high-pressure pump evenly distributes the injection solution from the storage tank into each horizontal injection branch. The injection solution is then sprayed into the soil to be remediated via corresponding swirl heads 224 in a swirling manner. Each expansion anti-surge shield, slidably connected to the outside of the protective outer cylinder, prevents small amounts of reagent from surging up from nearby soil. The combined use of the swirl heads and expansion anti-surge shields not only ensures uniform distribution of the injection solution in the soil, avoiding localized excessively high or low concentrations and improving remediation efficiency and effectiveness, but also increases the contact area between the reagent and the soil, reducing reagent drift and potentially minimizing reagent surging.

Description

Technical Field

[0001] This invention belongs to the field of soil remediation technology, specifically an intelligent spill-proof in-situ remediation reagent injection control system. Background Technology

[0002] Soil environment is one of the basic elements of ecosystem, and it is the foundation for human beings and organisms to survive and develop. Soil environment status not only directly affects national economic development and land resource and environmental security, but also relates to agricultural product safety and human health.

[0003] In-situ chemical oxidation remediation is a commonly used soil remediation technology. It involves injecting reagents into the ground to oxidize organic pollutants in the soil into substances such as benzene-free compounds and chlorinated organic compounds. The reagents are usually mixed reagents composed of two or more different reagents.

[0004] The current in-situ chemical oxidation remediation process involves pre-mixing two or more reagents and then injecting the mixture underground. In this process, the oxidizing power of the mixed reagents is significantly reduced before they come into contact with pollutants, thus failing to generate effective hydroxyl radicals and resulting in poor remediation outcomes. Furthermore, during construction, due to the high organic matter and carbonate content in the soil, reagent upwelling often occurs, causing much of the reagent to be lost and unable to reach the designated remediation area, which also affects the remediation effect.

[0005] Therefore, there is an urgent need for an in-situ remediation reagent injection device that can inject reagents at a certain depth in the soil and has an anti-overflow function. Summary of the Invention

[0006] To address the aforementioned problems, this invention provides an intelligent anti-overflow in-situ repair reagent injection control system.

[0007] The technical solution of the present invention is: an intelligent spill-proof in-situ repair reagent injection control system, comprising a main frame, a reagent injection assembly, an intelligent control module, an early warning and emergency response module, and a parameter monitoring module mounted on the main frame;

[0008] The reagent injection assembly includes a lifting mounting plate connected to the bottom of the main mounting frame via a hydraulic scissor lift, an anti-overflow injection tube located at the lower end of the lifting mounting plate, and an injection liquid storage tank connected to the anti-overflow injection tube via a connecting hose and equipped with a variable speed high pressure pump at the connection point.

[0009] The anti-overflow injection tube includes an injection main tube connected to the connecting hose, multiple horizontal injection branches that are connected to and parallel to each other through the injection main tube, an inner injection tube that is evenly distributed along the length of each horizontal injection branch and connected to the horizontal injection branch tube, and a protective outer cylinder located outside each inner injection tube with an open bottom. The bottom end of the inner injection tube is provided with a swirl head, and the protective outer cylinder is provided with an expansion anti-surge shield that can slide up and down along its outer wall.

[0010] The intelligent control module includes a central processing unit, a parameter adjustment unit connected to the central processing unit and providing injection parameters, and a human-computer interaction interface connected to the central processing unit and displaying the system status in real time.

[0011] The early warning and emergency response module includes an audible and visual alarm unit connected to the central processing unit and providing audible and visual alarms based on the detection results of the parameter monitoring module, and a remote alarm unit connected to the central processing unit and sending alarm information to management personnel via a 4G / 5G network.

[0012] The parameter monitoring module includes a monitoring well, an underground pressure sensor installed in the monitoring well, a GPS / GNSS receiver, an inclinometer array, and a soil moisture sensor.

[0013] Furthermore, the main mounting frame includes a fixed slide rail and a mounting crossbar slidably connected to the upper end of the fixed slide rail via a sliding vertical rod. The fixed slide rail is composed of multiple slide rail segments connected end to end, and the upper end of each slide rail segment is provided with a sliding groove that slidably connects to the sliding vertical rod. One end of each slide rail segment is provided with a plug interface, and the other end is provided with a plug-in post that matches the plug interface. Adjacent slide rail segments are connected by fastening bolts. The lifting mounting plate is connected to the mounting crossbar via the hydraulic scissor lift.

[0014] Note: The fixed slide rail is composed of slide rail segments connected end to end. The number of slide rail segments can be increased or decreased according to the changes in the area to be repaired, thereby adjusting the position of the reagent injection component. When the position of the mounting frame is moved, it is achieved by sliding the vertical rod back and forth in the sliding groove at the upper end of the slide rail segment. The position of the mounting frame and reagent injection component can be quickly adjusted through simple sliding operation, saving the time of reinstallation or adjustment. Adjacent slide rail segments are limited by plug-in pins and plug interfaces, and are fixedly connected by fastening bolts.

[0015] Furthermore, the variable speed high-pressure pump has a flow rate range of 5-20 GPM and a pressure range of 50-1000 psi.

[0016] Note: The variable speed high-pressure pump supports arbitrary adjustment within a flow rate range of 5-20 GPM and a pressure range of 50-1000 psi. By precisely controlling the injection pressure and flow rate, the mixing rate of the agent with pollutants in the soil can be accelerated, thereby improving remediation efficiency.

[0017] Furthermore, the reagent injection assembly also includes a pulse generator electrically connected to the central processing unit, the pulse generator being disposed within the connecting tubing.

[0018] Note: When injecting the injection solution from the storage tank into the injection main tube via the connecting hose, a programmable pulse generator emits a pulse to control the injection process, providing precise spray rate and time intervals. This ensures that the injection solution is accurately delivered to the soil according to the predetermined pattern and dosage, reducing the risk of spillage.

[0019] Furthermore, the pulse frequency of the pulse generator is 0.1-10Hz, and the duration of the transmitted pulse is 10-1000ms.

[0020] Explanation: By limiting the pulse frequency and duration of the pulse generator, the injection solution can penetrate soil particles more effectively, increase the distribution range of the injection solution in the soil, and reduce the loss of the injection solution on the soil surface.

[0021] Furthermore, the parameter monitoring module also includes a detection mounting frame, which includes a positioning main frame located at the center of the monitoring well, multiple sliding discs sequentially fitted onto the outer wall of the positioning main frame from top to bottom, and an electric telescopic rod located between two adjacent sliding discs. Each sliding disc is equipped with an underground pressure sensor, a GPS / GNSS receiver, an inclinometer array, and a soil moisture sensor on its sidewall.

[0022] Description: When in use, this detection mounting frame initially defines the position of each detection component within the monitoring well by positioning the main frame. Simultaneously, each sliding disc is positioned at different heights on the outer wall of the main frame, facilitating monitoring of soil at different depths. The monitoring depth can be adjusted via an electric telescopic rod between adjacent sliding discs. This allows for monitoring of underground pressure, surface deformation, surface uplift trend, and soil moisture content at different depths, improving the comprehensiveness and accuracy of the monitoring results.

[0023] Furthermore, the sliding disc has an open sidewall structure, and multiple mounting blocks distributed circumferentially are slidably connected inside the sliding disc. A miniature hydraulic cylinder is provided at the center of the sliding disc, which is connected to each mounting block in a corresponding manner. The underground pressure sensor, GPS / GNSS receiver, inclinometer array, and soil moisture sensor are respectively located on the sidewall of each mounting block.

[0024] Note: To meet the usage requirements of monitoring wells with different apertures, several mounting blocks are slidably connected within each sliding disc along the circumference. Each mounting block is driven by a miniature hydraulic cylinder to slide outward from the sliding disc until the underground pressure sensor, GPS / GNSS receiver, inclinometer array, and soil moisture sensor mounted on the mounting block come into contact with the soil on the inner wall of the monitoring well and begin monitoring. This helps to obtain more accurate data on underground pressure, surface deformation, surface uplift trend, and soil moisture content.

[0025] Furthermore, each of the sliding disks is equipped with a laser sensor at its bottom, and the laser sensor is covered with a transparent protective cover.

[0026] Explanation: A laser sensor is installed at the bottom of each sliding disk to detect the distance between two adjacent sliding disks, facilitating the adjustment of the depth of each sliding disk. The laser sensor is protected by a transparent protective cover to prevent dust, moisture, chemicals, or other potential pollutants in the monitoring well from directly contacting the laser sensor, thus affecting its normal operation and measurement accuracy. This ensures the lifespan of the laser sensor, guarantees its stable operation in harsh monitoring environments, and provides reliable monitoring data.

[0027] Furthermore, the lifting mounting plate is provided with reinforcing connecting rods on both the left and right sides, and the reinforcing connecting rods are slidably connected to the side wall of the sliding vertical rod.

[0028] Note: When the hydraulic scissor lift moves the lifting mounting plate up and down, the reinforcing connecting rods on its left and right sides provide a point of force, which improves the stability and reliability of the lifting mounting plate's movement.

[0029] Compared with the prior art, the beneficial effects of the present invention are:

[0030] (1) When the system of the present invention injects the injection solution into the soil to be repaired, the injection solution in the injection solution storage tank is evenly dispersed into each horizontal injection branch pipe by a variable speed high-pressure pump. At this time, the injection solution will be sprayed into the soil to be repaired in a swirling manner through the corresponding swirl head 224. The expansion anti-surge cover slidably connected to the outside of the protective outer cylinder can block a small amount of reagent from surging up from the nearby soil. Through the combined use of the swirl head and the expansion anti-surge cover, not only can the uniform distribution of the injection solution in the soil be ensured, avoiding the problem of local excessively high or low concentration, and improving the repair efficiency and effect, but it can also increase the contact area between the solution and the soil, reduce the drift of the solution, and may reduce the phenomenon of reagent surging up; when equipment In case of operational failure, an alarm message is sent to management personnel via a remote alarm unit using a 4G / 5G network. The status of electrical components can be controlled in real time through a human-machine interface. The remediated soil is monitored in real time using underground pressure sensors, GPS / GNSS receivers, tiltmeter arrays, and soil moisture sensors to measure underground pressure, millimeter-level surface deformation, surface uplift trend, and soil moisture content changes. The real-time monitoring data can be used to analyze the dynamic changes in the soil remediation process, providing comprehensive data support for project management and supervision. In summary, the intelligent spill-proof in-situ remediation reagent injection control of this invention provides a comprehensive, intelligent, and efficient solution to prevent remediation reagent spillage on the surface.

[0031] (2) This invention uses a positioning main frame to initially define the position of each detection component in the monitoring well. At the same time, each sliding disc is set at a different height on the outer wall of the positioning main frame, which facilitates the monitoring of soil at different depths. The monitoring depth can also be adjusted by an electric telescopic rod between two adjacent sliding discs. The invention monitors the underground pressure, surface deformation, surface uplift trend and soil moisture content of soil at different depths, which improves the comprehensiveness and accuracy of the monitoring results. In order to meet the usage requirements of monitoring wells with different apertures, several mounting blocks are slidably connected in each sliding disc along the circumference. Each mounting block is driven by a micro hydraulic cylinder to slide out of the sliding disc until the underground pressure sensor, GPS / GNSS receiver, inclinometer array and soil moisture content sensor installed on the mounting block come into contact with the soil on the inner wall of the monitoring well and monitor it. This helps to obtain more accurate data on underground pressure, surface deformation, surface uplift trend and soil moisture content. Attached Figure Description

Detailed Implementation

[0040] To further understand the content of the present invention, the present invention will be described in detail below through embodiments.

[0041] Example 1

[0042] like Figure 1 As shown, an intelligent spill-proof in-situ repair reagent injection control system includes a main mounting frame 1, a reagent injection assembly 2, an intelligent control module 3, an early warning and emergency response module 4, and a parameter monitoring module 5 mounted on the main mounting frame 1.

[0043] like Figure 6 , Figure 7As shown, the main mounting frame 1 includes a fixed slide rail 10 and a mounting crossbeam 11 slidably connected to the upper end of the fixed slide rail 10 via a sliding vertical rod 110. The fixed slide rail 10 is composed of three slide rail segments 12 connected end to end, and the upper end of each slide rail segment 12 is provided with a sliding groove 120 that slidably connects to the sliding vertical rod 110. One end of each slide rail segment 12 is provided with a plug interface 121, and the other end is provided with a plug-in post 122 that matches the plug interface 121. Adjacent slide rail segments 12 are connected by fastening bolts 123. The lifting mounting plate 21 is connected to the mounting crossbeam 11 via a hydraulic scissor lift 20. The fixed slide rail 10 is composed of each slide rail segment 12 connected end to end, and can... The number of slide rail sections 12 is increased or decreased according to the changes in the area to be repaired, thereby adjusting the position of the reagent injection assembly 2. When the position of the mounting frame 11 is moved, it is achieved by sliding the vertical rod 110 back and forth in the sliding groove 120 at the upper end of the slide rail section 12. The position of the mounting frame 11 and the reagent injection assembly 2 can be quickly adjusted through simple sliding operation, saving the time of reinstallation or adjustment. Adjacent slide rail sections 12 are limited by the insertion post 122 and the insertion interface 121, and are fixedly connected by fastening bolts 123. The hydraulic scissor lift 20 adopts existing technology.

[0044] The reagent injection assembly 2 includes a lifting mounting plate 21 connected to the bottom of the mounting main frame 1 via a hydraulic scissor lift 20, an anti-overflow injection tube 22 located at the lower end of the lifting mounting plate 21, an injection solution storage tank 23 connected to the anti-overflow injection tube 22 via a connecting hose 230 and equipped with a variable speed high pressure pump 231 at the connection point, and a pulse generator 24 located inside the connecting hose 230. Both the variable speed high pressure pump 231 and the pulse generator 24 adopt existing technologies.

[0045] The variable speed high-pressure pump 231 has a flow rate range of 5 GPM and a pressure range of 50 psi. By precisely controlling the injection pressure and flow rate, it can accelerate the mixing rate of the agent with pollutants in the soil, thereby improving the remediation efficiency.

[0046] The pulse generator 24 has a pulse frequency of 0.1Hz and a pulse duration of 10ms. When the injection solution in the injection solution storage tank 23 is injected into the injection main tube 220 through the connecting hose 230, the pulse generator 24 emits a programmable pulse to control the injection process of the injection solution, providing a precise injection rate and time interval, ensuring that the injection solution can be accurately delivered to the soil according to the predetermined pattern and dosage, reducing the risk of spillage. By limiting the pulse frequency and pulse duration of the pulse generator 24, the injection solution can penetrate soil particles more effectively, increase the distribution range of the injection solution in the soil, and reduce the loss of the injection solution on the soil surface.

[0047] like Figure 2 , Figure 3As shown, the anti-overflow injection tube 22 includes an injection main tube 220 connected to the connecting hose 230, five horizontal injection branches 221 that are connected to the injection main tube 220 and distributed parallel to each other, an inner injection tube 222 that is evenly distributed along the length of each horizontal injection branch 221 and connected to the horizontal injection branch 221, and a protective outer cylinder 223 located outside each inner injection tube 222 with an open bottom. The bottom end of the inner injection tube 222 is provided with a swirl head 224, and the protective outer cylinder 223 is provided with an expansion anti-surge shield 225 that can slide up and down along its outer wall. The swirl head 224 and the expansion anti-surge shield 225 are existing technologies.

[0048] The intelligent control module 3 includes a central processing unit 30, a parameter adjustment unit 31 connected to the central processing unit 30 and providing injection parameters, and a human-machine interface 32 connected to the central processing unit 30 and displaying the system status in real time. The central processing unit 30, the parameter adjustment unit 31 and the human-machine interface 32 all adopt existing technologies.

[0049] The early warning and emergency response module 4 includes an audible and visual alarm unit 40 connected to the central processing unit 30 and providing audible and visual alarms based on the detection results of the parameter monitoring module 5, and a remote alarm unit 41 connected to the central processing unit 30 and sending alarm information to management personnel via a 4G / 5G network. Both the audible and visual alarm unit 40 and the remote alarm unit 41 adopt existing technologies.

[0050] The parameter monitoring module 5 includes a monitoring well 50, an underground pressure sensor 51, a GPS / GNSS receiver 52, an inclinometer array 53, and a soil moisture sensor 54 installed in the monitoring well 50. The underground pressure sensor 51, the GPS / GNSS receiver 52, the inclinometer array 53, and the soil moisture sensor 54 all adopt existing technologies.

[0051] Example 2

[0052] The difference between this embodiment and Embodiment 1 is that:

[0053] The variable speed high-pressure pump 231 has a flow range of 15 GPM and a pressure range of 500 psi;

[0054] The pulse generator 24 has a pulse frequency of 5Hz and a pulse duration of 500ms.

[0055] Example 3

[0056] The difference between this embodiment and Embodiment 1 is that:

[0057] The variable speed high-pressure pump 231 has a flow range of 20 GPM and a pressure range of 1000 psi.

[0058] The pulse generator 24 has a pulse frequency of 10Hz and a pulse duration of 1000ms.

[0059] Example 4

[0060] This embodiment discloses a method for using an intelligent spill-proof in-situ repair reagent injection control system according to Embodiment 2, specifically including the following steps:

[0061] S1. As needed, connect several slide rail segments 12 end to end, and limit the connection between two adjacent slide rail segments 12 by inserting the plug 122 and the plug interface 121. At the same time, fix them by fastening bolts 123 to form the first fixed slide rail 10. Then, take the same number of slide rail segments 12 and connect them end to end in the above connection method to form the second fixed slide rail 10. Place the first fixed slide rail 10 and the second fixed slide rail 10 in parallel at the soil to be repaired. Take the installation crossbar 11 and slide the sliding vertical bar 110 at its bottom end to the sliding groove 120 at the upper end of the first fixed slide rail 10 and the second fixed slide rail 10.

[0062] S2. Start the hydraulic scissor lift 20. The hydraulic scissor lift 20 drives the lifting mounting plate 21 to move downward. When the bottom end of the protective outer cylinder 223 is inserted into the soil to be repaired, due to the obstruction of the soil, the expansion anti-surge cover 225 slides against the protective outer cylinder 223. The expansion anti-surge cover 225 is always located at the top of the soil to be repaired. Start the variable speed high pressure pump 231. The variable speed high pressure pump 231 sends the injection liquid in the injection liquid storage tank 23 into the injection main pipe 220 through the connecting hose 230 and evenly distributes it into each horizontal injection branch pipe 221. Then, the injection liquid in each horizontal injection branch pipe 221 flows into the soil to be repaired through the injection inner pipe 222 and the protective outer cylinder 223 at its bottom end. During the operation of the variable speed high pressure pump 231, the injection parameters are adjusted through the parameter adjustment unit 31.

[0063] S3. When the injection fluid in each horizontal injection branch tube 221 passes through the injection inner tube 222 at its bottom end, the injection fluid will be sprayed into the soil to be repaired in a swirling manner through the corresponding swirl head 224.

[0064] S4. When equipment malfunctions, alarm information is sent to management personnel via remote alarm unit 41 using 4G / 5G network, and the equipment status of hydraulic scissor lift 20 and variable speed high pressure pump 231 is controlled in real time through human-machine interface 32.

[0065] S5. After the remediation reagent is injected, the underground pressure of the remediated soil is monitored by the underground pressure sensor 51, the surface deformation of the remediated soil is monitored at the millimeter level by the GPS / GNSS receiver 52, the surface uplift trend is monitored by the tiltmeter array 53, and the change of soil moisture content after remediation is monitored by the soil moisture sensor 54.

[0066] Example 5

[0067] The difference between this embodiment and Embodiment 2 is that:

[0068] like Figure 4 , Figure 5 As shown, the parameter monitoring module 5 also includes a detection mounting frame 55. The detection mounting frame 55 includes a positioning main frame 550 located at the center inside the monitoring well 50, three sliding discs 551 sequentially fitted onto the outer wall of the positioning main frame 550 from top to bottom, and an electric telescopic rod 552 located between two adjacent sliding discs 551. Each sliding disc 551 has a ground pressure sensor 51, a GPS / GNSS receiver 52, an inclinometer array 53, and a soil moisture sensor 54 installed on its side wall. When in use, the detection mounting frame 55 uses the positioning main frame 550 to initially determine the position of each detection component within the monitoring well 50. Furthermore, each sliding disc 551 is set at a different height on the outer wall of the positioning main frame 550, which facilitates monitoring of soil at different depths. The monitoring depth can also be adjusted by the electric telescopic rod 552 between two adjacent sliding discs 551, and the underground pressure, surface deformation, surface uplift trend and soil moisture content of soil at different depths can be monitored, which improves the comprehensiveness and accuracy of the monitoring results. Among them, the electric telescopic rod 552, underground pressure sensor 51, GPS / GNSS receiver 52, inclinometer array 53 and soil moisture content sensor 54 all adopt existing technologies.

[0069] The sliding disc 551 has an open sidewall, and four mounting blocks 553 are slidably connected inside the sliding disc 551 and distributed circumferentially. A miniature hydraulic cylinder 554, corresponding to each mounting block 553, is located at the center of the sliding disc 551. A ground pressure sensor 51, a GPS / GNSS receiver 52, a tiltmeter array 53, and a soil moisture sensor 54 are respectively mounted on the sidewall of each mounting block 553. To meet the usage requirements of monitoring wells 50 with different diameters, four mounting blocks 554 are slidably connected inside each sliding disc 551 and distributed circumferentially. Several mounting blocks 553 are circumferentially slidably connected, and each mounting block 553 is driven by a micro hydraulic cylinder 554 to slide outward of the sliding disk 551 until the underground pressure sensor 51, GPS / GNSS receiver 52, inclinometer array 53 and soil moisture sensor 54 mounted on the mounting block 553 come into contact with the soil on the inner wall of the monitoring well 50 and monitor it. This helps to obtain more accurate data on underground pressure, surface deformation, surface uplift trend and soil moisture content. The micro hydraulic cylinder 554 adopts existing technology.

[0070] Each sliding disk 551 is equipped with a laser sensor 555 at its bottom. The laser sensor 555 is surrounded by a transparent protective cover 556. The purpose of setting the laser sensor 555 at the bottom of each sliding disk 551 is to detect the distance between two adjacent sliding disks 551, so as to facilitate the adjustment of the depth of each sliding disk 551. The transparent protective cover 556 protects the laser sensor 555 from dust, moisture, chemicals or other potential pollutants in the monitoring well 50 directly contacting the laser sensor 555, thereby affecting its normal operation and measurement accuracy. This can ensure the service life of the laser sensor 555, ensure that the laser sensor 555 can operate stably in harsh monitoring environments, and provide reliable monitoring data. The laser sensor 555 adopts existing technology.

[0071] The lifting mounting plate 21 is provided with reinforcing connecting rods 210 on both the left and right sides. The reinforcing connecting rods 210 are slidably connected to the side wall of the sliding vertical rod 110. When the hydraulic scissor lift 20 drives the lifting mounting plate 21 to move up and down, the reinforcing connecting rods 210 on both the left and right sides provide the force points, which improves the stability and reliability of the movement of the lifting mounting plate 21.

[0072] Example 6

[0073] The difference between this embodiment and embodiment 4 is that:

[0074] In step S5, when installing the detection mounting frame 55, the positions of the underground pressure sensor 51, GPS / GNSS receiver 52, inclinometer array 53, and soil moisture sensor 54 within the monitoring well 50 are initially defined by the positioning main frame 550. Different monitoring depths are adjusted by the electric telescopic rod 552 between two adjacent sliding discs 551. The micro hydraulic cylinder 554 drives each mounting block 553 to slide outward from the sliding disc 551 until the underground pressure sensor 51, GPS / GNSS receiver 52, inclinometer array 53, and soil moisture sensor 54 installed on the mounting block 553 come into contact with and monitor the soil on the inner wall of the monitoring well 50.
