Description

Technical Field

[0001] This application relates to the technical field of contaminated site remediation, and in particular to an odor control method and system for remediation of coking-type contaminated sites. Background Technology

[0002] Coking-type contaminated sites are characterized by their large area, typical pollution types, and severe pollution levels, making them a key focus and challenge in environmental management. Unlike general civil engineering projects, minimizing the impact of odors emitted from coking-type contaminated sites on surrounding areas, especially residential areas, is particularly important during the remediation process.

[0003] Because the odor from contaminated sites can spread to surrounding areas due to environmental factors such as wind direction, wind speed, air pressure, and weather, it is usually necessary to control the odor in the contaminated area during the remediation process to reduce its impact on the surrounding areas. Currently, common odor control methods typically involve setting up high-altitude sprayers around the contaminated site and spraying deodorizing agents continuously around the site 24 hours a day. This creates a water mist barrier around the site, preventing the odor from spreading and thus controlling the odor.

[0004] In the process of developing this application, the inventors discovered that the technology has at least the following problems: the continuous spraying of deodorizing agents by the spray piles consumes a large amount of water resources, which constitutes a waste of resources. Summary of the Invention

[0005] To help reduce water waste during the remediation of contaminated sites, this application provides a method and system for odor control in the remediation of coking-type contaminated sites.

[0006] Firstly, this application provides an odor control method for the remediation of coking-related contaminated sites, employing the following technical solution: the method is applied to an odor control system, which includes a plurality of boundary odor sensors uniformly arranged along the boundary line of the contaminated site and a plurality of spray devices uniformly arranged along the boundary line of the contaminated site; the method includes:

[0009] Obtain the location of the abnormal boundary odor sensor;

[0010] The first abnormal area is determined within the contaminated site based on the location of the abnormal boundary odor sensor.

[0011] The spray device located in the first abnormal area is activated.

[0012] The above technical solution utilizes boundary odor sensors to detect the boundary area of ​​contaminated sites in real time. Then, the spraying device is activated only when odor levels exceed the standard, spraying the first abnormal area corresponding to the excessive odor to block the spread of the odor. Compared with the odor control method of spraying deodorants all-round and continuously, this method reduces water waste and has better energy-saving and environmental protection properties.

[0013] In one specific implementation scheme, determining the first abnormal area within the contaminated site based on the location of the abnormal boundary odor sensor includes: constructing a circular area within the contaminated site with the location of the abnormal boundary odor sensor as the center and a preset first distance as the radius; and setting the constructed circular area as the first abnormal area.

[0016] In one specific implementation scheme, determining the odor diffusion direction based on the positions of the sequentially triggered outer and inner edge odor sensors includes: drawing a ray passing through the triggered outer edge odor sensor starting from the triggered inner edge odor sensor, and setting the direction pointed to by the ray as the odor diffusion direction; controlling the start of the spray device located in the control direction includes: constructing a circular second abnormal area with the intersection of the ray and the boundary line of the contaminated plot as the center and a preset first distance as the radius; and controlling the start of the spray device located in the second abnormal area.

[0017] In one specific implementation, drawing a ray from the triggered inner edge odor sensor to the triggered outer edge odor sensor includes: if the triggered inner edge odor sensor is unique, then the unique inner edge odor sensor is used as the starting point; if the triggered inner edge odor sensor is not unique, then the center point of the area constructed by multiple triggered inner edge odor sensors is used as the starting point; if the triggered outer edge odor sensor is unique, then a ray passing through the unique outer edge odor sensor is drawn; if the triggered outer edge odor sensor is not unique, then the center point of the area constructed by multiple triggered outer edge odor sensors is used as the path point, and a ray passing through the path point is drawn.

[0018] In a specific implementation scheme, constructing a circular second abnormal region with the intersection of the ray and the boundary line of the contaminated site as the center and a preset first distance as the radius includes: if the triggered outer edge odor sensor is unique, then constructing a circular second abnormal region with the intersection of the ray and the boundary line of the contaminated site as the center and a preset first distance as the radius; if the triggered outer edge odor sensor is not unique, then determining the number of triggered outer edge odor sensors, and resetting the value corresponding to the first distance according to the number of triggered sensors, wherein the reset first distance is greater than the preset first distance; constructing a circular second abnormal region with the intersection of the ray and the boundary line of the contaminated site as the center and the reset first distance as the radius.

[0019] In one specific implementation, after the spray device located in the control direction is started, the method further includes: recording the cumulative start time of the spray device; and if no boundary odor sensor is triggered during the period when the cumulative start time reaches a preset standard time, then turning off the spray device located in the control direction.

[0020] Secondly, this application provides an odor control system for the remediation of coking-related contaminated sites, employing the following technical solution: the system includes a plurality of boundary odor sensors uniformly arranged along the boundary line of the contaminated site and a plurality of spray devices uniformly arranged along the boundary line of the contaminated site; the system further includes: a boundary odor detection module, used to acquire the boundary detection values ​​of the plurality of boundary odor sensors in real time; an abnormal odor definition module, used to compare the boundary detection values ​​with a preset first standard value, and to set boundary odor sensors with boundary detection values ​​greater than the first standard value as abnormal boundary odor sensors; an abnormal odor location module, used to acquire the location of the abnormal boundary odor sensors; an abnormal area determination module, used to determine a first abnormal area within the contaminated site based on the location of the abnormal boundary odor sensors; and a spray device control module, used to control the spray devices located within the first abnormal area to start.

[0021] Thirdly, this application provides a computer device that adopts the following technical solution: it includes a memory and a processor, wherein the memory stores a computer program that can be loaded by the processor and executed as any of the above-mentioned odor control methods for remediation of coking-type contaminated sites.

[0022] Fourthly, this application provides a computer-readable storage medium that employs the following technical solution: storing a computer program capable of being loaded by a processor and executing any of the above-mentioned odor control methods for remediation of coking-type contaminated sites.

By using boundary odor sensors to detect the boundary area of ​​the contaminated site in real time, the spraying device is activated only when the odor exceeds the standard, spraying the first abnormal area corresponding to the excessive odor to block the spread of the odor; compared with the odor control method of spraying deodorant all the way and continuously, it reduces the waste of water resources and has better energy saving and environmental protection.

[0025] 2. Based on the triggering status of the inner and outer odor sensors, the diffusion direction of odorous gases can be predicted. Then, before the odor in the contaminated area spreads to the boundary area, the spray device in the diffusion direction is turned on in advance to pre-intercept the odorous gases, further improving the odor control system's effectiveness in controlling odors in the contaminated area.

[0033] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0034] This application discloses an odor control method for the remediation of coking-related contaminated sites. (Refer to...) Figure 1 This method is applied to an odor control system. The odor control system includes several boundary odor sensors 1 evenly arranged on the boundary line of the contaminated site, several outer edge odor sensors 2 and inner edge odor sensors 3 evenly arranged in the inner area of ​​the contaminated site, and several spray devices 4 evenly arranged on the boundary line of the contaminated site. Among them, the boundary odor sensors 1, outer edge odor sensors 2 and inner edge odor sensors 3 are connected in sequence to form a ring, and the outer edge odor sensors 2 are located between the inner edge odor sensors 3 and the boundary odor sensors 1. Each boundary odor sensor 1, outer edge odor sensor 2 and inner edge odor sensor 3 has a unique number. The odor control system can determine the specific location information of the boundary odor sensors 1, outer edge odor sensors 2 and inner edge odor sensors 3 based on the unique number.

[0035] The boundary odor sensor 1, outer edge odor sensor 2, and inner edge odor sensor 3 can be gas detection sensors, primarily detecting odorous gases such as carbon disulfide, hydrogen sulfide, and ammonia. The spray device 4 can be a high-altitude spray pile. Specifically, a solenoid valve can be installed on each high-altitude spray pile, allowing the odor control system to control the opening and closing of the spray device 4 by controlling the on / off state of the solenoid valve. When activated, the spray device 4 sprays deodorant to suppress odors in the area surrounding the spray device. It is understood that the spray device 4 can also include a fog cannon truck and a drone spraying device. The odor control system can send the location information of the odor area to the fog cannon truck and drone, which can then automatically or manually spray deodorant at designated points in the abnormal area based on the location information provided by the control system. This embodiment uses a high-altitude spray pile as an example for illustration.

[0036] Reference Figure 2 The method includes the following steps:

[0037] S10 acquires the boundary detection values ​​of several boundary odor sensors in real time.

[0038] Specifically, during the remediation of coking-related contaminated sites, the odor control system will detect odor gases in the boundary area of ​​the contaminated site in real time through boundary odor sensors, so as to obtain the odor gas detection values ​​of each location in the boundary area of ​​the contaminated site in real time, that is, the boundary detection values ​​of the boundary odor sensors.

[0039] S20, compare the boundary detection value with the preset first standard value, and set the boundary odor sensor with the boundary detection value greater than the first standard value as the abnormal boundary odor sensor.

[0040] Specifically, when the odor control system acquires the boundary detection value, it compares the boundary detection value with a preset first standard value. If the boundary detection value is not greater than the first standard value, it indicates that no odor has spread in the boundary area. If the boundary detection value is greater than the first standard value, it indicates that odor has spread in the boundary area. Then, the boundary odor sensor with a boundary detection value greater than the first standard value is set as an abnormal boundary odor sensor. In other words, the boundary odor sensor that detects odor exceeding the standard is set as an abnormal boundary odor sensor.

[0041] S30, obtain the location of the odor sensor at the abnormal boundary.

[0042] Specifically, based on the unique number of the boundary odor sensor corresponding to the abnormal boundary odor sensor, the odor control system can quickly determine the specific location information of the abnormal boundary odor sensor on the boundary line of the contaminated site.

[0043] S40, determine the first abnormal area within the contaminated site based on the location of the odor sensor at the abnormal boundary.

[0044] Specifically, after determining the location of the odor sensor at the abnormal boundary, the control system identifies the location of the odor sensor at the abnormal boundary within the contaminated site as the first abnormal area. The first abnormal area is the area where odor diffusion occurs and odor needs to be controlled.

[0045] In one embodiment, refer to Figure 3 The step of determining the first anomalous area within the contaminated site based on the location of the odor sensor at the anomalous boundary can be specifically performed as follows:

[0046] First, using the location B1 of the abnormal boundary odor sensor as the center, and then using a preset first distance R1 as the radius, a circular area is constructed within the contaminated area. This circular area is then set as the first abnormal area Y1. The first distance R1 can be preset according to the area of ​​the contaminated area and the actual needs of the customer.

[0047] S50, control the start of the spray device located in the first abnormal area.

[0048] Specifically, in the initial state, all spray devices are in the off state; after the control system determines the first abnormal area, it first identifies the spray devices located within the first abnormal area, and then controls the spray devices located within the first abnormal area to start spraying deodorizing liquid in order to control the odor gas in the first abnormal area and reduce the impact of the odor gas spreading to the surrounding areas.

[0049] This application utilizes boundary odor sensors to detect the boundary area of ​​contaminated sites in real time. Then, it activates spray devices only when excessive odors are detected, spraying the first abnormal area corresponding to the excessive odor to block its spread. In this application, all spray devices are off by default. Only when an abnormality occurs in the boundary area of ​​the contaminated site, the spray devices in the abnormal area are activated to control the spread of odor gases at specific times and locations. Compared to the odor control method of continuous, all-around spraying of deodorants, this method saves water resources and deodorant usage, and is more energy-efficient and environmentally friendly.

[0050] In one embodiment, in order to predict the spread of odors so that the odor control system can activate the spray device in advance to pre-intercept odor gases, the odor control method for remediation of coking-type contaminated sites may further include the following steps:

[0051] The control system simultaneously acquires the outer edge detection values ​​of several outer edge odor sensors and the inner edge detection values ​​of several inner edge odor sensors in real time. It then compares these outer edge and inner edge detection values ​​with a first standard value, which corresponds to the boundary detection value. Outer edge odor sensors with outer edge detection values ​​greater than the first standard value are then marked as triggered, as are inner edge odor sensors with inner edge detection values ​​greater than the first standard value. If, within a preset time period, both outer edge and inner edge odor sensors are sequentially marked as triggered (the preset time period can be set by the operator according to actual needs, such as 60 seconds, 70 seconds, or 80 seconds, etc.), then... The interval between at least one inner edge odor sensor and at least one outer edge odor sensor transitioning to the triggered state is less than a preset time period. This confirms the presence of outer edge and inner edge odor sensors that are sequentially marked as triggered. Consequently, it is determined that odorous gas is spreading from the inner area to the outer area within the contaminated site. The direction of odor diffusion is determined based on the positions of the sequentially triggered outer edge and inner edge odor sensors. Then, the spray device located in the diffusion direction is activated. This achieves the effect of pre-intercepting odorous gas by activating the spray device in the diffusion direction before the odor spreads to the boundary area within the contaminated site, further improving the odor control system's effectiveness in controlling odors within the contaminated site.

[0052] It should be noted that the outer and inner edge odor sensors are triggered sequentially. The corresponding actual scenario is that the odor inside the contaminated site spreads from the central area to the outer edge, but the odor has not yet reached the boundary line of the contaminated site. In other words, the boundary odor sensor has not been triggered at this time. Opening the spray device at this time is equivalent to setting a lead time, that is, opening the spray device in advance to intercept the odor gas before the odor spreads to the boundary. This reduces the possibility that a small amount of odor gas has already crossed the boundary line of the contaminated site and affected the odor control effect when the boundary odor sensor is triggered and the spray device is opened, thus further improving the odor control effect of the odor control system within the contaminated site.

[0053] In one embodiment, the step of determining the odor diffusion direction based on the positions of the sequentially triggered outer and inner odor sensors can be specifically performed as follows:

[0054] First, starting from the triggered inner odor sensor, draw a ray passing through the triggered outer odor sensor, and set the direction of the ray as the odor diffusion direction. Specifically, considering the different coverage areas of the odor gas, the number of sequentially triggered outer and inner odor sensors may be unique or not. In real-world scenarios, the larger the coverage area of ​​the odor gas, the more likely the number of triggered outer and inner odor sensors will increase. Therefore, the determination of the diffusion starting point is handled in the following two ways:

[0055] Method 1: If the triggered inner edge odor sensor is unique, then the position corresponding to the unique triggered inner edge odor sensor shall be taken as the starting point.

[0056] Method 2: If the triggered inner edge odor sensor is not unique, then the starting point is the position corresponding to the center point of the area constructed by multiple triggered inner edge odor sensors.

[0057] Determining the diffusion direction also involves the following two methods:

[0058] Method 1: If the triggered outer edge odor sensor is unique, draw a ray from the starting point through the position corresponding to the unique outer edge odor sensor, and determine the direction of the ray as the diffusion direction of the odor gas;

[0059] Method 2: If the triggered peripheral odor sensor is not unique, the center point of the area constructed by multiple triggered peripheral odor sensors is used as the path point, and a ray is drawn from the starting point through the path point; the direction of the ray is determined as the diffusion direction of the odor gas.

[0060] Once the direction of the odorous gas diffusion is determined, the intersection point between the ray and the boundary line of the contaminated area is found. Then, a second circular abnormal area is constructed with the intersection point as the center and a preset first distance as the radius. The spray device located in the second abnormal area is then activated to pre-intercept the odorous gas diffusing in that direction. The first distance can be preset by the staff.

[0061] Specifically, refer to Figure 4 Taking the example where both the triggered outer edge odor sensor and the triggered inner edge odor sensor are unique, the process of determining the second abnormal area is as follows:

[0062] Starting from the triggered inner edge odor sensor N1, a ray L1 is drawn from the starting point N1 through the outer edge odor sensor W1. Then, a circular area is drawn with the intersection point J1 between the ray L1 and the boundary of the contaminated plot as the center and the preset first distance R1 as the radius. The drawn circular area is the second abnormal area Y2.

[0063] In one embodiment, considering that the number of peripheral odor sensors triggered sequentially represents the range of odor gas diffusion towards the boundary, the more peripheral odor sensors are triggered, the larger the coverage area of ​​the odor gas diffusion towards the boundary tends to be. If the number of peripheral odor sensors triggered is not considered and the first distance is always set to a fixed value to determine the second abnormal area, the spraying range of the spraying device may be smaller than the odor gas diffusion range, resulting in some odor gas diffusing out of the contaminated area from the edge of the spraying area. Therefore, in order to further improve the odor control system's control effect on odor gases within the contaminated area, the step of constructing a circular second abnormal area with the intersection of the ray and the boundary line of the contaminated area as the center and the preset first distance as the radius can be specifically executed as follows:

[0064] First, determine the number of peripheral odor sensors that are triggered sequentially. If only one peripheral odor sensor is triggered, construct a circular second abnormal area with the intersection of the ray and the boundary line of the contaminated site as the center and a preset first distance as the radius. If multiple peripheral odor sensors are triggered, reset the value of the first distance based on the number of triggered peripheral odor sensors, and then reset the first distance, ensuring the reset first distance is greater than the preset first distance. Then, construct a circular second abnormal area with the intersection of the ray and the boundary line of the contaminated site as the center and the reset first distance as the radius. Based on the above example, if the preset first distance is R1, the reset first distance increases by a factor of n for each additional peripheral odor sensor triggered sequentially, where n > 1, and the specific value can be preset by the staff. For example, when two peripheral odor sensors are triggered sequentially, the corresponding first distance is adjusted to nR1; when three peripheral odor sensors are triggered sequentially, the corresponding first distance is adjusted to n... 2 R1.

[0065] Specifically, refer to Figure 5 Taking the example that neither the triggered outer edge odor sensor nor the triggered inner edge odor sensor is unique, the process of determining the second abnormal area is as follows:

[0066] First, determine the center point Z1 of the two inner edge odor sensors and the center point Z2 of the two outer edge odor sensors. Then, starting from the center point Z1, draw a ray L2 that passes through the center point Z2. Next, using the intersection point J2 between the ray L2 and the boundary of the contaminated area as the center, draw a circular area with a newly set first distance nR1 as the radius. The drawn circular area is the second abnormal area Y2.

[0067] In one embodiment, considering that during the diffusion process of odorous gases, there may be situations where the odorous gases only drift within the contaminated area and do not diffuse to the boundary area of ​​the contaminated area; that is, only the inner and outer odor sensors are triggered sequentially, but the boundary odor sensor is not triggered for a long time; thus causing the spray device to work ineffectively for a long time, affecting the odor control effect; in order to further improve the control effect of the odor control system, after the odor control system controls the spray device located in the diffusion direction to start, the following steps can also be performed:

[0068] After the odor control system starts the spray device, the cumulative start time of the spray device is recorded. If no boundary odor sensor is triggered during the cumulative start time, it is determined that the odor gas has not spread to the boundary area of ​​the contaminated site, and then the spray device located in the diffusion direction is shut down. This reduces the possibility of the spray device working ineffectively for a long time and further improves the control effect of the odor control system.

[0069] Figure 2 This is a flowchart illustrating an odor control method for remediation of coking-related contaminated sites in one embodiment. It should be understood that, although... Figure 2 The steps in the flowchart are shown sequentially as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows; unless explicitly stated otherwise, there is no strict order requirement for the execution of these steps, and they can be executed in other orders; and Figure 2 At least some of the steps in the process may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these sub-steps or stages is not necessarily sequential, but can be executed in turn or alternately with other steps or at least some of the sub-steps or stages of other steps.

[0070] Based on the above method, this application also discloses an odor control system for the remediation of coking-related contaminated sites.
