Description

Background Art

[0002] The manufacture of ships requires the processing, refining and welding of various metals, which may produce various exhaust gases. The use of ships requires diesel engines to provide power, which also produces various exhaust gases. With the increasingly stringent regulations on exhaust emissions, the shipping industry has an increasing demand for reducing emission pollution and improving economic benefits. In order to take into account economic efficiency and meet emission requirements, exhaust gas treatment at all stages is an issue that needs urgent attention.

[0003] In order to meet the requirements for exhaust gas emissions, the currently commonly used treatment method is: to collect the exhaust gas generated by each process in a centralized manner through an exhaust fan, then discharge the generated exhaust gas into the water, and treat various exhaust gases through seawater.

BRIEF DESCRIPTION OF THE DRAWINGS

[0077] Figure 1 It is a schematic flow chart of a waste gas treatment method based on environmental requirements provided by one embodiment of the present invention;

[0078] Figure 2 It is a structural schematic diagram of an exhaust gas treatment system based on environmental requirements provided by one embodiment of the present invention. DETAILED DESCRIPTION

[0079] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0080] In order to solve the above problems, a waste gas treatment method based on environmental requirements provided in the embodiments of the present application will be introduced and explained in detail through the following specific embodiments.

[0081] Reference Figure 1 , showing a schematic flow chart of a waste gas treatment method based on environmental requirements provided by an embodiment of the present invention.

[0082] In one embodiment, the method is applicable to a central control system of a ship, which can be specifically installed in a control terminal of the ship. The control terminal can be installed in a central control room of the ship, and a user can control and manage various functions of the ship through the control terminal.

[0083] Wherein, as an example, the waste gas treatment method based on environmental requirements may include:

[0084] S11. After obtaining the environmental demand information, call the monitoring camera to capture the environmental image of the surrounding environment of the ship exhaust port in real time.

[0085] In one embodiment, the environmental demand information may be the environmental requirements of the environment in which the ship is located. For example, when a ship is docked at an inland port, the emission substances, emission concentrations, and emission amounts of exhaust gas at the inland port may be obtained to obtain environmental demand information. For another example, when a ship is sailing on the high seas, the emission substances, emission concentrations, and emission amounts of exhaust gas at the high seas may be obtained to obtain environmental demand information.

[0086] Since different places or regions have different requirements for exhaust gas, the environmental requirements of the area where the ship is currently located can be obtained, and then the exhaust gas emitted by the ship can be determined according to the requirements of the area. If the exhaust gas emitted by the ship does not meet the environmental requirements, the exhaust gas can be recycled to avoid exhaust gas pollution.

[0087] Ships are generally powered by diesel engines, which are also used as fuel. Diesel may not burn completely during the combustion process, resulting in a large amount of exhaust gas.

[0088] Traditional ships (such as sand and gravel transport ships, ferry ships, and container transport ships) generally have an exhaust gas discharge pipe on the top of the deck, and exhaust gas is discharged through the exhaust gas discharge pipe.

[0089] In order to accurately detect whether the exhaust gas meets environmental requirements, an image of the exhaust gas emission pipe can be taken, and then the image can be identified to determine whether there is exhaust gas. Specifically, the monitoring camera on the ship deck is called to take real-time images of the surrounding environment of the ship exhaust port of the exhaust gas emission pipe to obtain an environmental image.

[0090] If a sensor is installed in the exhaust pipe for exhaust gas detection, since the exhaust gas contains a large amount of incompletely burned gas, the high temperature of the exhaust gas after long-term use will cause the sensor to malfunction and affect the detection accuracy. The environmental image can be taken from a longer distance, and then the content of the image can be used to determine whether the exhaust gas is exhaust gas, which can avoid the impact of high temperature exhaust gas.

[0091] S12. When it is determined based on the environmental image that there is exhaust gas at the exhaust port of the ship, a plurality of exhaust gas sample data are extracted around the exhaust port of the ship, and a real-time concentration value of the exhaust gas is determined based on the plurality of exhaust gas sample data.

[0092] In one embodiment, an image recognition model may be called to perform image recognition on an environmental image, and the model may be used to determine whether there is exhaust gas at the exhaust port of a ship. For example, the model may be used to identify whether there is black gas in the environmental image. If there is black gas, it is determined that there is exhaust gas.

[0093] After confirming the presence of waste gas, the concentration value of the waste gas can be determined to obtain the real-time concentration value. The concentration of waste gas may be high or low, and area a has higher requirements for waste gas emissions, while area b has lower requirements for waste gas emissions. The calculated real-time concentration value may be high, but because area b has lower requirements for waste gas emissions, it may meet environmental requirements and no waste gas recovery treatment is required. Similarly, the calculated real-time concentration value may be low, but because area a has higher requirements for waste gas emissions, waste gas recovery treatment may be required to meet environmental requirements. Therefore, it is possible to determine whether the currently emitted waste gas meets the environmental requirements for emissions based on the size of the real-time concentration value.

[0094] In order to accurately determine the real-time concentration value, a gas analysis instrument can be called around the ship's exhaust port to extract a number of exhaust gas sample data, and then the real-time concentration value of the exhaust gas is calculated based on the concentration value of each exhaust gas sample data.

[0095] In an optional embodiment, the exhaust gas may be generated just after combustion in the engine. At this time, the exhaust gas contains a large amount of heat, and the presence of the exhaust gas can be detected by the amount of heat.

[0096] Optionally, the environmental image may be a heat source image captured by a heat source camera. In a specific implementation, a heat source monitoring camera may be arranged on the deck of the ship, and then the heat source monitoring camera may be called to capture an image of the surrounding environment of the ship's exhaust port to obtain an environmental image. The content displayed in the environmental image includes the captured object and the color of the object, and the color of the object changes with the change of the object. For example, the higher the temperature, the brighter the color, and conversely, the lower the temperature, the darker the color.

[0097] Wherein, as an example, determining the presence of exhaust gas at the exhaust port of the ship based on the environmental image may include the following sub-steps:

[0098] S21. Determine the area of ​​the heat source in the heat source image according to a preset chromaticity interval value to obtain a heat source area value.

[0099] S22. If the heat source area value is greater than a preset area value, it is determined that exhaust gas exists at the exhaust port of the ship.

[0100] S23. If the heat source area value is smaller than a preset area value, the heat source area and the discharge port area are extracted from the environmental image, and the interval distance value between the discharge port area and the heat source area is calculated. When the interval distance value is smaller than the preset distance value, it is determined that exhaust gas exists at the exhaust port of the ship.

[0101] In one embodiment, if there is exhaust gas, the heat of the exhaust gas will diffuse in the surroundings, causing the temperature of the surroundings to also increase. Therefore, the area size of the heat source in the image can be determined according to the color of the corresponding temperature, and whether there is exhaust gas can be determined based on the area size.

[0102] For example, the range of chromaticity values ​​for temperatures greater than 40 degrees Celsius can be determined to obtain a preset chromaticity range value, and then the area in the heat source image that belongs to this chromaticity value range can be determined, and this area can be determined as the heat source area. The image area corresponding to this area is then calculated to obtain the heat source area value.

[0103] Next, it can be determined whether the heat source area value is greater than the preset area value. If the heat source area value is greater than the preset area value, it means that there is a large amount of high-calorie gas around the exhaust port of the ship in the image. This gas may be caused by exhaust gas. Therefore, it can be determined that there is exhaust gas at the exhaust port of the ship.

[0104] In another optional embodiment, the exhaust gas may be discharged at a high speed. During the discharge process, due to its high discharge rate, the heat mainly diffuses in one direction, and the high heat area around the ship's exhaust port is not large. In order to accurately detect the exhaust gas discharged at a high speed, if the heat source area value is less than the preset area value, the heat source area and the discharge port area of ​​the environmental image are identified, wherein the heat source area is the area in the environmental image that belongs to the preset chromaticity interval value, and the discharge port area is the location area of ​​the exhaust gas discharge port in the environmental image. The heat source area and the discharge port area are extracted from the environmental image respectively, and then the image interval distance between the discharge port area and the heat source area is calculated to obtain the interval distance value. Specifically, the pixel points at the image edge of the two areas can be extracted, and the interval distance between the two areas in the environmental image can be calculated by the coordinates of the two pixel points.

[0105] Then it can be determined whether the interval distance value is less than the preset distance value. If the interval distance value is less than the preset distance value, it means that the heat in the heat source area may be diffused from the discharge port area, which may be caused by the exhaust gas discharged from the discharge port. At this time, it can be determined that there is exhaust gas at the exhaust port of the ship.

[0106] In another optional embodiment, after extracting the heat source area, the regional shape of the heat source area can be identified. If it is a continuous line shape, it means that the heat source may also be caused by exhaust gas emissions, and it can also be determined that there is exhaust gas at the exhaust port of the ship.

[0107] In another optional embodiment, if there are multiple heat source areas and the shapes of the areas are discontinuous, the material detection instrument on the deck can also be called to detect the substances in the air on the deck. If the detected air contains pollutants, it can also be determined that there is exhaust gas at the exhaust port of the ship.

[0108] The color of the heat source image can be used to quickly and accurately determine whether exhaust gas exists, effectively improving the accuracy of detection.

[0109] In an optional embodiment, the exhaust gas is a large amount of smoke, and the smoke is generally gray. The smoke will reduce the clarity of the ship's exhaust port. Therefore, the environment around the ship's exhaust port can be determined by the clarity to determine whether there is exhaust gas around the ship's exhaust port. Specifically, the environment image includes: a plurality of high-definition images taken by a high-definition camera.

[0110] In a specific implementation, a high-definition surveillance camera can be set on the deck of the ship, and then the high-definition surveillance camera is called to continuously shoot images of the surrounding environment of the ship's exhaust port to obtain a number of high-definition images. Specifically, the images can be taken at a preset time interval, for example, once every one second, and a number of high-definition images can be obtained after continuous shooting for 10 seconds.

[0111] Wherein, as an example, determining the presence of exhaust gas at the exhaust port of the ship based on the environmental image may include the following sub-steps:

[0112] S31, calling a preset image optimization module to optimize the clarity of each high-definition image to obtain a plurality of optimized images.

[0113] S32: Identify the marked image area of ​​each optimized image, and calculate the image clarity of each marked image area.

[0114] S33, selecting two from the plurality of image sharpnesses and calculating the difference to obtain a plurality of sharpness difference values.

[0115] S34. Count the clarity difference values ​​that are greater than a preset difference value from the multiple clarity difference values. If the number of clarity difference values ​​that are greater than the preset difference value is greater than a preset clarity number value, it is determined that exhaust gas exists at the exhaust port of the ship.

[0116] or;

[0117] S35. If the numerical values ​​of the plurality of clarity differences are in an increasing sequence, it is determined that exhaust gas exists at the exhaust port of the ship.

[0118] In one embodiment, the clarity of each high-definition image can be optimized to obtain a plurality of optimized images. Among them, a preset image optimization module can be called to optimize the clarity. The preset image optimization module can be a CNN model, which can be obtained by the user collecting multiple images in advance for model training. Optionally, the image optimization process can also be performed in a conventional manner.

[0119] Next, the image clarity of each optimized image can be calculated respectively. Specifically, the marked image area of ​​each optimized image can be identified first, and the image clarity of each marked image area can be calculated. The marked image area can be the sky or object area in the surrounding environment of the ship exhaust port, and then the clarity of the area in the optimized image is calculated to obtain the image clarity corresponding to each optimized image.

[0120] In specific operations, a conventional image recognition model can also be called to identify the surrounding objects of the ship exhaust port in the image or the sky area facing the ship exhaust port opening, and then calculate the clarity of the area in the optimized image to obtain the image clarity corresponding to each optimized image.

[0121] Then, two of the plurality of image sharpnesses may be selected and the difference may be calculated to obtain a plurality of sharpness difference values. Specifically, the difference between each image sharpness and the image sharpness of the first optimized image may be calculated to obtain a plurality of sharpness difference values.

[0122] For example, if there are 10 image sharpnesses, the difference between the image sharpness of the first optimized image and the image sharpness of the second optimized image can be calculated to obtain the first sharpness difference; then the difference between the image sharpness of the first optimized image and the image sharpness of the third optimized image can be calculated to obtain the second sharpness difference, and so on, until the difference between the image sharpness of the first optimized image and the image sharpness of the tenth optimized image is calculated to obtain the ninth sharpness difference. After calculation, a total of 9 sharpness difference values ​​are obtained.

[0123] The difference in image clarity between two adjacent optimized images may be calculated to obtain a plurality of clarity difference values.

[0124] Then, the number of clarity differences greater than the preset difference is counted. If the number of clarity differences greater than the preset difference is greater than the preset clarity number, it means that the clarity around the ship exhaust port is low, and it can be determined that the environmental state of the environment around the ship exhaust port is that exhaust gas exists.

[0125] By calculating the difference in image clarity between the two images, it is determined whether there is exhaust gas or smoke based on the difference in clarity. If there are multiple large clarity differences, it means that a lot of exhaust gas or smoke is generated. It is determined that the environmental condition of the environment around the ship's exhaust port is that exhaust gas exists, and it needs to be recovered in a timely manner afterwards.

[0126] Similarly, after calculating multiple clarity differences, the multiple clarity differences can be arranged in order. If the numerical values ​​of the multiple clarity differences after arrangement are in an increasing sequence, it means that the clarity differences are getting larger and larger, and correspondingly, the clarity of the image is getting lower and lower. The lower the clarity, the more likely it is that it is caused by exhaust gas, so it can be determined that there is exhaust gas at the exhaust port of the ship.

[0127] The present invention calculates the image clarity through multiple high-definition images, and can quickly and accurately determine whether exhaust gas exists by combining the difference in clarity and the order of arrangement, thereby effectively improving the detection accuracy.

[0128] In one embodiment, since the exhaust gas may drift away immediately, or the wind speed in the environment of the ship is relatively high, the exhaust gas may also be blown away, resulting in changes in the concentration of the exhaust gas. Therefore, it is necessary to collect multiple exhaust gas air samples and determine the exhaust gas concentration value based on the multiple air samples. As an example, the extraction of multiple exhaust gas sample data and the determination of the real-time exhaust gas concentration value based on the multiple exhaust gas sample data may include the following sub-steps:

[0129] S121. After determining the exhaust port area value of the ship exhaust port and the exhaust flow value of the exhaust gas, calculate the ratio of the exhaust flow value to the exhaust port area value to obtain the exhaust flow rate value.

[0130] S122, using the emission flow rate value and the preset time interval to calculate the emission distance value, sequentially acquiring exhaust gas sample data with the emission distance value as the interval, obtaining a plurality of exhaust gas sample data, and calculating the gas concentration value corresponding to each exhaust gas sample data.

[0131] S123, calculating an average value of a plurality of gas concentration values ​​to obtain a real-time concentration value.

[0132] In an actual operation mode, the exhaust port area value of the ship exhaust port and the emission flow value of the exhaust gas can be determined, and then the ratio of the emission flow value to the exhaust port area value can be calculated to obtain the emission flow rate value.

[0133] Specifically, the exhaust port area value of the ship's exhaust port can be obtained by querying the ship's record information. Then, the exhaust port sensor of the ship detects the emission flow value of the real-time exhaust gas from the ship's exhaust port. The ratio of the emission flow value and the exhaust port area value is calculated to obtain the emission flow rate value, which can be the exhaust gas emission speed value.

[0134] Next, the emission distance value can be calculated using the emission flow rate value and the preset time interval, wherein the preset time interval can be an interval set by the user, such as 1 second, 0.5 second, etc. The emission distance value can be obtained by calculating the product of the emission flow rate value and the preset time interval. The exhaust gas sample data can be acquired in sequence with the emission distance value as the interval for collecting data to obtain a plurality of exhaust gas sample data.

[0135] For example, if the emission distance value is 1 meter, a sample data can be collected every one meter, and several exhaust gas sample data can be obtained. The specific collection method is to carry an air sampling instrument in the drone, and then collect and control the air sampling instrument to take a sample every one meter, and then use the air sampling instrument to analyze the substances in the air and the concentration of the substances. Specifically, conventional instruments can be used for analysis operations, and the analyzed data can be uploaded to the control terminal to obtain several exhaust gas sample data. Then, the air concentration value can be extracted from each exhaust gas sample data, and the gas concentration value corresponding to each exhaust gas sample data can be obtained.

[0136] Finally, the average of several gas concentration values ​​can be calculated to obtain the real-time concentration value.

[0137] In another optional embodiment, sampling may be performed directly at preset time intervals. For example, sampling may be performed once every second around the exhaust port. Ten exhaust gas sample data may be obtained by sampling ten times.

[0138] S13. After extracting the required concentration value from the environmental demand information, if it is determined that the real-time concentration value is greater than the required concentration value, determining the exhaust gas type according to a plurality of exhaust gas sample data.

[0139] After calculating the real-time concentration value, the required concentration value can be extracted from the environmental demand information, and then it is determined whether the real-time concentration value is greater than the required concentration value. If the real-time concentration value is greater than the required concentration value, it means that the exhaust gas discharged at this time does not meet the exhaust gas emission requirements of the x area, and exhaust gas recovery treatment is required to meet the environmental requirements. At this time, the exhaust gas type can be determined based on a number of the exhaust gas sample data.

[0140] Among them, the exhaust gas type is the substance type corresponding to the substance with the largest content in the exhaust gas. Because the speed of the ship is different at different times, the fuel used may also be different. For example, during the day, it is necessary to travel fast, and diesel and diesel flame retardant are needed to enhance power; at night, it is necessary to travel slowly, and only diesel may be needed.

[0141] Different substances may produce waste gas at different times, and different waste gas substances can have different waste gas recovery methods. In order to distinguish different waste gas recovery methods, the content of each pollutant or waste gas substance can be extracted from each waste gas sample data, and then the sum of the contents of several waste gas substances is calculated to obtain the sum value of each waste gas substance, and then the sum value with the largest value is selected from the multiple sum values, and the type of waste gas substance corresponding to the largest sum value is taken as the waste gas type. For example, the content of xx waste gas substance is the highest, and the type of xx waste gas substance can be taken as the waste gas type. The subsequent waste gas recovery method can mainly target the xx waste gas substance to reduce the content of the substance, so that the waste gas can meet the requirements.

[0142] S14. Match the corresponding waste gas recovery equipment based on the waste gas type, and call the waste gas recovery equipment to perform waste gas recovery processing according to the size of the real-time concentration value until the real-time concentration value is less than the required concentration value.

[0143] After determining the exhaust gas type, the corresponding exhaust gas recovery equipment can be matched according to the exhaust gas type. In one implementation, the shipping personnel can pre-set the corresponding exhaust gas recovery equipment for different exhaust gas substances, and bind the relationship between the exhaust gas type and the exhaust gas recovery equipment. After determining the exhaust gas type, the corresponding exhaust gas recovery equipment can be found based on the binding relationship.

[0144] Finally, the waste gas recovery equipment can be called to perform waste gas recovery treatment according to the size of the real-time concentration value until the real-time concentration value is less than the required concentration value.

[0145] According to the description of the above embodiments, the generated waste gas contains a lot of heat. If the high-temperature waste gas is directly recycled, the high temperature may not only affect the waste gas recycling equipment, but also waste the waste gas heat. In order to reasonably utilize the waste gas heat to improve the utilization rate of resources, as an example, calling the waste gas recycling equipment to perform waste gas recycling according to the size of the real-time concentration value may include the following sub-steps:

[0146] S41, identifying the chromaticity value of the heat source area of ​​the heat source image, obtaining the heat source chromaticity value, and determining the exhaust gas temperature value according to the heat source chromaticity value.

[0147] S42. If the exhaust gas temperature value is greater than a preset temperature value, the heat source conversion device collects the exhaust gas and performs heat conversion on the exhaust gas to absorb the heat of the exhaust gas to obtain a converted gas.

[0148] S43, detecting the exhaust gas concentration of the conversion gas, and after obtaining the conversion concentration value, calculating the difference between the real-time concentration value and the conversion concentration value to obtain a first concentration difference.

[0149] S44. If the first concentration difference is greater than a preset first difference, the converted gas is transported to a waste gas recovery device for waste gas recovery treatment.

[0150] Specifically, the chromaticity value of the heat source area of ​​the heat source image can be identified to obtain the heat source chromaticity value, and the exhaust gas temperature value can be determined according to the heat source chromaticity value. Specifically, different temperatures correspond to different chromaticity values. For example, 50 degrees Celsius can correspond to xx1 chromaticity value, and 60 degrees Celsius can correspond to xx2 chromaticity value. The heat value of the exhaust gas can be determined according to the size of the chromaticity value.

[0151] Next, it can be determined whether the exhaust gas temperature value is greater than the preset temperature value. If the exhaust gas temperature value is greater than the preset temperature value, it means that the heat of the exhaust gas is high. If the exhaust gas is directly recovered, it may cause equipment failure. The exhaust gas from the exhaust gas discharge pipe can be first transported to the heat source conversion device, and the heat source conversion device can collect the exhaust gas and perform heat conversion on the exhaust gas to absorb the heat of the exhaust gas, and then charge the ship's battery with the absorbed heat. After the heat conversion is completed, the exhaust gas containing high heat can be converted into conversion gas.

[0152] Specifically, the heat source conversion device can be arranged on the deck of the ship, and the heat source conversion device can be connected to the exhaust gas emission pipe through a conventional pipeline, and the exhaust gas from the exhaust gas emission pipe is transmitted to the heat source conversion device through the pipeline for heat conversion.

[0153] At this time, the exhaust gas concentration of the conversion gas can be detected to obtain the conversion concentration value. Specifically, a sample can be extracted from the conversion gas, and then the air analyzer is called to calculate its concentration to obtain the conversion concentration value. Specifically, the concentration of the exhaust gas substance corresponding to the exhaust gas type can be obtained.

[0154] According to the description of the above example, the real-time concentration value is a concentration value including multiple substances. The concentration of the exhaust gas substance corresponding to the exhaust gas type can be extracted from the real-time concentration value, and then the difference between the real-time concentration value and the converted concentration value can be calculated to obtain the first concentration difference.

[0155] If the first concentration difference is greater than the preset first difference, it means that the concentration of the substance in the gas is relatively high, and the converted gas can be transported to the waste gas recovery equipment for waste gas recovery treatment.

[0156] Specifically, an exhaust gas recovery device can also be installed on the deck. The exhaust gas recovery device can be connected to the exhaust gas discharge pipe and the heat source conversion device through pipelines respectively, and the gas from the heat conversion device can be transmitted to the exhaust gas recovery device through the pipeline. The exhaust gas recovery device can specifically be a conventional exhaust gas purification device.

[0157] If the first concentration difference is less than the preset first difference, it means that the concentration of the substance in the gas is low, and it can be determined whether the conversion concentration value is less than the required concentration value. If the conversion concentration value is less than the required concentration value, the heat source conversion device can be allowed to directly discharge the gas. If the conversion concentration value is greater than the required concentration value, the converted gas of the heat source conversion device can be transported to the waste gas recovery device for waste gas recovery treatment.

[0158] Exhaust gas is purified through exhaust gas recovery equipment, so that the gas can be purified to meet emission requirements.

[0159] In one embodiment, the discharged waste gas may contain a variety of waste gas materials and waste gas substances, and the waste gas materials and waste gas substances may contain useful substances. In order to recover various useful substances and avoid waste of resources, as an example, calling the waste gas recovery device to perform waste gas recovery treatment according to the size of the real-time concentration value may include the following sub-steps:

[0160] S51. Select any one of the exhaust gas sample data as target sample data, and call a material analysis instrument to identify several types of substances contained in the target sample data.

[0161] S52. If at least one of the several types of substances is the same as a type recorded in the preset type list, the exhaust gas is transmitted to a gas classifier for gas classification, and a residual concentration value of the exhaust gas after classification is calculated.

[0162] S53: Calculate the difference between the real-time concentration value and the remaining concentration value to obtain a second concentration difference.

[0163] S54: If the second concentration difference is greater than a preset second difference, the classified waste gas is transported to a waste gas recovery device for waste gas recovery treatment.

[0164] Specifically, one of the exhaust gas sample data may be arbitrarily selected as the target sample data, and a material analysis instrument may be called to identify the types of substances contained in the target sample data.

[0165] Optionally, the calculated real-time concentration value also includes the concentration values ​​of multiple substances, and the real-time concentration value can be read to obtain several substance types, each substance corresponding to a substance type.

[0166] After determining the types of substances, it can be determined whether at least one of the types of substances is the same as the type recorded in the preset type list. In a specific operation, the user can pre-record multiple types of substances to be recycled, and then construct a list using the multiple types of substances to be recycled to obtain a preset type list.

[0167] If at least one of the several types of substances is the same as the type recorded in the preset type list, it means that there are substances in the exhaust gas that need to be recovered, and the exhaust gas can be transmitted to the gas classifier through a pipeline for gas classification.

[0168] Specifically, a gas classifier can also be installed on the deck, which can be connected to the exhaust gas discharge pipeline through a pipeline, and the exhaust gas is transmitted to the gas classifier through the pipeline. The gas classifier can be a conventional gas separation device. The gas separation device can liquefy and distill the exhaust gas and finally separate it into oxygen, nitrogen and other useful gases.

[0169] After the classification and separation are completed, the concentration value of the classified gas can be calculated to obtain the residual concentration value. The residual concentration value can specifically be the concentration value of the substance corresponding to the substance type.

[0170] Then, the difference between the real-time concentration value and the remaining concentration value is calculated to obtain a second concentration difference value. It is determined whether the second concentration difference value is greater than a preset second difference value.

[0171] If the second concentration difference is greater than the preset second difference, it means that the gas concentration still cannot meet the demand, and the classified and separated gas can be transported to the waste gas recovery equipment through a pipeline for waste gas recovery treatment.

[0172] Specifically, an exhaust gas recovery device may also be installed on the deck. The exhaust gas recovery device may be connected to the exhaust gas discharge pipe and the gas classifier through pipelines respectively. The gas from the gas classifier may be transmitted to the exhaust gas recovery device through the pipeline. The exhaust gas recovery device may specifically be a conventional exhaust gas purification device.

[0173] If the second concentration difference is less than the preset second difference, it means that the concentration of the substance in the gas is low, and it can be determined whether the remaining concentration value is less than the required concentration value. If the remaining concentration value is less than the required concentration value, the gas classifier can be allowed to directly discharge the gas.

[0174] The gas classifier can separate the required or recyclable substances, and after completion, the waste gas can be recycled and purified to meet the emission requirements.

[0175] In one embodiment, after the exhaust gas recovery process is started, the ship may continue to produce high-concentration exhaust gas, and the exhaust gas recovery process fails to process a large amount of high-concentration exhaust gas. Continuous emission of exhaust gas not only affects the surrounding environment, but also may cause the ship to violate the requirements of the region where it is located, and then the ship receives a warning. In order to promptly notify the ship's technicians and shipping personnel, the method further includes the following steps as an example:

[0176] S15. Count the processing time of the waste gas recovery treatment. If the processing time is longer than the preset time, obtain the concentration value of the waste gas after treatment to obtain the treatment concentration value.

[0177] S16. If the treatment concentration value is greater than the preset alarm concentration value, an alarm prompt is triggered.

[0178] Specifically, after the waste gas recovery process is started, the duration of the waste gas recovery process from the start to the current time node can be counted to obtain the processing duration.

[0179] Then determine whether the processing time is greater than the preset time. If the processing time is greater than the preset time, it means that the processing has been going on for a period of time and the exhaust gas concentration may have decreased. At this time, the concentration value of the exhaust gas after treatment can be obtained to obtain the processing concentration value.

[0180] The concentration value of the exhaust gas around the exhaust port of the ship can be detected. Specifically, the operation method of the above example can be used to extract a number of exhaust gas sample data around the exhaust port of the ship, and then the concentration value of the exhaust gas is calculated based on the number of exhaust gas sample data to obtain the treatment concentration value.

[0181] Then determine whether the treatment concentration value is greater than the preset alarm concentration value. If the treatment concentration value is greater than the preset alarm concentration value, it means that after a period of waste gas recovery treatment, the discharged waste gas still cannot meet the environmental needs or environmental requirements of the current area. Therefore, an alarm prompt can be triggered.

[0182] In specific operations, the alarm information can be displayed on the control terminal, and the control terminal can control the ship's broadcast to play the alarm information to notify dock personnel and technicians.

[0183] In this embodiment, the embodiment of the present invention provides an exhaust gas treatment method based on environmental requirements, and its beneficial effects are: after obtaining the exhaust gas emission demand information, the present invention can call the monitoring camera to take real-time environmental images of the surrounding environment of the ship's exhaust port; when it is determined based on the environmental image that there is exhaust gas at the ship's exhaust port, the real-time concentration value of the exhaust gas is determined; if it is determined that the real-time concentration value is greater than the required concentration value, the exhaust gas recovery equipment is called to perform exhaust gas recovery treatment according to the size of the real-time concentration value until the real-time concentration value is less than the required concentration value; the present invention can not only monitor the exhaust gas emission concentration in real time, but also recover the exhaust gas according to the air quality requirements, thereby improving the efficiency of exhaust gas treatment, so as to reduce the exhaust gas in the environment and achieve green environmental protection.
