Description

Technical Field

[0001] The present invention belongs to the technical field of long channel cooling, and in particular relates to a cooling system and method for a long channel with high-temperature airflow and multiple follow-up heat dissipation points. Background Art

[0002] In mining, rock temperatures generally rise with increasing depth, especially during excavation operations in zones of high geothermal anomalies. Furthermore, as mining intensity increases, the continuous operation and movement of large amounts of high-power equipment increases the amount of heat released by these equipment. In tunneling, during excavation and construction of tunnels in high-temperature strata, heat from the high-temperature strata and groundwater is transferred into the tunnel space, further increasing the ambient temperature of the working area. Furthermore, as in mining, the continuous operation and movement of large amounts of high-power equipment further raises the tunnel temperature. Long-term, continuous work in high-temperature environments can seriously harm workers' physical and mental health, reduce their work efficiency, and increase the risk of accidents. It can also significantly impact the cooling efficiency of underground equipment, increasing equipment failure rates and further increasing maintenance costs.

[0003] Whether it's deep coal tunneling, coal face mining, or high-temperature tunneling, the conditions can all be summarized as "long channels with high-temperature airflow and multiple moving heat sinks." To address this unique condition, two cooling methods are currently commonly used: conventional cold air flooding and spraying an insulation layer onto the rock face. Conventional cold air flooding suffers from the following main issues: 1. Significant energy loss and high cost; 2. Cooling effectiveness is easily limited by wind speed; 3. Lack of precision, unable to accurately locate cooling areas; 4. Due to the long cold air delivery channel, heat exchange between the cold air and the rock face is relatively inefficient, resulting in significant cooling waste before and after work, and poor operator experience; 5. Lack of flexibility, lack of targeted cooling of high-power equipment that moves during operation. The method of spraying an insulation layer on the rock wall surface has the following main problems: 1. The material cost is high, and the rock walls of long passages need to be sprayed with an isolation layer; 2. The construction requirements are high, and the thickness of the spray layer has strict standards and requirements; 3. The subsequent maintenance cost is high. Whether it is a roadway or a tunnel, it will deform over time, and the failed rock wall needs to be re-sprayed with an insulation layer.

[0004] To sum up, although there is some technical support for cooling the special working condition of high temperature heat damage caused by "long channel high temperature airflow and multiple follow-up heat dissipation points", the existing problems are also very significant. There is an urgent need to provide a new cooling system and method suitable for long channels. Summary of the Invention

[0016] The long continuous distributed optical fiber temperature detector is installed in the middle of one side of the long channel, with its length direction consistent with the extension of the long channel, its outer end extending to the outside of the long channel, and its inner end extending to a position close to the working surface; the long continuous distributed optical fiber temperature detector is used to collect the temperature signal of the entire long channel during the construction process;

[0017] The waste liquid treatment and recycling module is arranged at the bottom of the long channel, and includes two drainage grooves excavated on both sides of the bottom of the long channel, a liquid collection pool excavated in the outer area of ​​the long channel and connected to the two drainage grooves, and a purification device installed in the liquid collection pool;

[0022] Furthermore, the outer surface of each equipment train is covered with a layer of thermally conductive plastic. This not only isolates the equipment from direct contact with moisture, reducing the risk of corrosion damage, but also ensures good thermal conductivity, thus not affecting the normal heat dissipation process of the equipment.

[0023] In this invention, fixed spray brackets are installed in the high-walled, long, hot tunnel area to facilitate support for the integrated receiving sensor A and three intelligent spray cooling modules A. Multiple pairs of retractable connecting rods are installed on a multi-unit equipment train to facilitate support for multiple connected sets of detachable steel pipe brackets. This allows for the formation of mobile spray brackets that can follow the movement of the multi-unit equipment train at the top of the multi-unit equipment front passage area, the multi-unit equipment passage area, and the multi-unit equipment rear passage area. Extending one end of the multiple sets of detachable steel pipe brackets into the multi-unit equipment front passage area provides support for the integrated receiving sensor B, three intelligent spray cooling modules B, and module partition controller B in the multi-unit equipment front passage area. Extending the other end of the multiple sets of detachable steel pipe brackets into the multi-unit equipment rear passage area provides support for the integrated receiving sensor D, three intelligent spray cooling modules D, and module partition controller D in the multi-unit equipment rear passage area. Connecting a waste heat recovery and storage system between two adjacent equipment trains facilitates the recovery and storage of waste heat generated in the equipment train and the surrounding space. By installing integrated receiving sensors near the air inlet in the high-walled, long, and hot aisle areas, the front aisle area for multiple servo devices, the multi-servo aisle area, and the rear aisle area, it is possible to obtain temperature, humidity, and wind speed data near the air inlet. This allows the spraying action of the intelligent spray cooling modules in these aisle areas to be controlled based on the environmental parameters near the air inlet, thereby reducing the ambient temperature in these areas to within the desired temperature range. By configuring a modular partition controller, after receiving temperature, humidity, and wind speed data near the air inlet, combined with the set channel temperature and humidity data, optimal spray parameters and optimal spray spacing can be determined. This allows for intelligent and scientific control of the spraying action of the intelligent spray cooling modules in these aisle areas, thereby facilitating the rational control of spray parameters such as spray pressure, spray volume, and spray direction at each spray point. This effectively improves the utilization efficiency of the spray liquid and avoids waste of spray liquid and energy.The outer surface of the high-pressure atomizing nozzle is provided with multiple ranging laser radars, which can facilitate the use of ranging laser radars to detect vehicles and pedestrians. If vehicles and pedestrians are detected within the set range, a vehicle and pedestrian approach signal is sent to the module partition controller of the channel area. When the module partition controller receives the vehicle and pedestrian approach signal, it can control the multiple high-pressure atomizing nozzles within the set range to stop spraying operations, and control the multiple high-pressure atomizing nozzles within the set range to restart spraying operations after the vehicle and pedestrian approach signal disappears. In this way, a more intelligent spraying operation can be achieved, and at the same time, the adverse effects of the spraying operation on pedestrians and driving can be avoided; three intelligent spray cooling modules B are set in the three-level temperature control module in front of the follow-up device, and three intelligent spray cooling modules D are set in the three-level temperature control module behind the follow-up device. In this way, three-level soft spray cooling can be easily achieved in the channel area in front of multiple follow-up devices and the channel area behind multiple follow-up devices, and the comfort of the operators can be further ensured through a graded and stepped cooling method. Utilizing highly insulated delivery pipelines to supply spray liquid to each channel ensures that the spray liquid reaches each intelligent spray cooling module at the specified delivery temperature, thereby ensuring effective spray cooling. Long, continuous distributed fiber optic temperature probes installed throughout the long channel facilitate acquisition of temperature distribution data across the entire channel, enabling real-time verification of cooling effectiveness and facilitating adjustment of spray parameters for each intelligent spray cooling module. A waste liquid treatment and recycling module facilitates collection, storage, and purification of the collected and stored spray liquid, facilitating multiple recycling of the spray liquid. This system boasts a high degree of automation and effective cooling, automatically cooling long, high-walled, hot channels, and areas in front of, behind, and behind multiple servo equipment. Furthermore, it rationally controls spray parameters such as spray pressure, volume, and direction at each spray point, effectively improving spray liquid utilization and avoiding waste of spray liquid and energy.

[0029] S14: First, multiple pairs of retractable connecting rods are installed on the multiple equipment trains, and the spans of multiple sets of detachable steel pipe brackets are determined according to the three-level cooling area. Then, the multiple sets of detachable steel pipe brackets are connected in sequence and arranged on the top of the three-level cooling area. At the same time, they are fixedly connected to the top ends of the multiple pairs of retractable connecting rods to form a follow-up spray bracket for the equipment train;

[0033] Step 2: Install the intelligent spray cooling module;

[0034] S21: Determine the temperature of the cooling water to be used and determine the spray parameters of the high-pressure atomizing nozzle;

[0035] S22: Under the operating conditions of normal air flow in the long channel and normal operation of the multi-section equipment train, calculate and determine the spacing between the nozzles in the intelligent spray cooling module in each cooling and temperature control area. The specific method is as follows:

[0036] a) For high-walled, hot, and long channel areas:

[0037] First, determine the number and spacing of high-pressure atomizing nozzles in a single intelligent spray cooling module A, so that the two pre-installed high-pressure atomizing nozzles in the module perform spray operations with the same spray parameters. Simultaneously, use data simulation calculations to obtain the long channel temperature curve. Then, increase the number of high-pressure atomizing nozzles one by one until the module A can cool the area where it is located to 1°C below the required temperature. Stop increasing the number of high-pressure atomizing nozzles and ensure that the multiple high-pressure atomizing nozzles are always evenly spaced.

[0038] Then, determine the spacing between the intelligent spray cooling modules A, install one intelligent spray cooling module A at the front side of the top of the fixed spray bracket near the air inlet, and after a single intelligent spray cooling module A has been working for a period of time, use the lowest temperature point in the long channel temperature curve obtained by data simulation calculation as the installation position of the next intelligent spray cooling module A, and then install the second intelligent spray cooling module A; after two intelligent spray cooling modules A have been working simultaneously for a period of time, use the lowest temperature point in the long channel temperature curve as the installation position of the next intelligent spray cooling module A, and then install the third intelligent spray cooling module A, thereby determining the initial spacing between the three intelligent spray cooling modules A;

[0039] Finally, three intelligent spray cooling modules A were used to perform synchronous spraying operations. The initial spacing between the three intelligent spray cooling modules A was verified using the temperature distribution signals collected in real time by a long continuous distributed optical fiber temperature detector, and the actual installation position was further adaptively adjusted.

[0040] b) For the front channel area of ​​multiple follower devices:

[0041] First, the wind speed signal B, temperature signal 1B, and humidity signal B near the air inlet are collected in real time using the integrated receiving sensor B to obtain wind speed data B, temperature data 1B, and humidity data B near the air inlet. The temperature signal 2B of the overall temperature distribution of the area is collected in real time using the long continuous distributed optical fiber temperature detector to obtain temperature distribution data 2B for the entire area. Then, based on the wind speed data B, temperature data 1B, and humidity data B near the air inlet, the temperature distribution data 2B for the entire area, and the set channel temperature and humidity data, the cooling capacity required for spray cooling is calculated, thereby obtaining the total number of high-pressure atomizing nozzles required.

[0042] Then, the total number of high-pressure atomizing nozzles is distributed according to the ratio of 3:2:1. Then, according to the distribution results, they are installed on the three intelligent spray cooling modules B of the first, second and third levels respectively. At the same time, the multiple high-pressure atomizing nozzles on each intelligent spray cooling module B are installed at equal intervals.

[0043] Next, determine the initial spacing between the three intelligent spray cooling modules B, install the first-level intelligent spray cooling module B at the front side of the top of the equipment train follow-up spray bracket near the air inlet, and after the first-level intelligent spray cooling module B has been working for a period of time, use the lowest temperature point in the long channel temperature curve obtained by data simulation calculation as the installation position of the second-level intelligent spray cooling module B, and then install the second-level intelligent spray cooling module B; after the first-level and second-level intelligent spray cooling modules B have been working simultaneously for a period of time, use the lowest temperature point in the long channel temperature curve obtained by data simulation calculation as the installation position of the third-level intelligent spray cooling module B, and then install the third-level intelligent spray cooling module B, thereby determining the initial spacing between the three intelligent spray cooling modules B;

[0044] Finally, three intelligent spray cooling modules B were used to perform synchronous spraying operations. The initial spacing between the three intelligent spray cooling modules B was verified using the temperature distribution signals collected in real time by a long continuous distributed optical fiber temperature detector, and the actual installation position was further adaptively adjusted. At the same time, when the three intelligent spray cooling modules B were working simultaneously, the lowest temperature point in the long channel temperature curve obtained based on data simulation calculations was used as the starting position of the multi-section equipment train.

[0045] c) For multiple follower device channel areas:

[0046] First, determine the number and spacing of high-pressure atomizing nozzles in a single intelligent spray cooling module C, so that the two pre-installed high-pressure atomizing nozzles in the single intelligent spray cooling module C perform spray operations with the same spray parameters. Simultaneously, use data simulation calculations to obtain the long channel temperature curve. Then, increase the number of high-pressure atomizing nozzles one by one until the single intelligent spray cooling module C cools the multi-follower equipment channel area to 1°C below the required temperature. Stop increasing the number of high-pressure atomizing nozzles and ensure that the multiple high-pressure atomizing nozzles in the single intelligent spray cooling module C are always evenly spaced.

[0047] Then, the spacing between the intelligent spray cooling modules C is determined, and an intelligent spray cooling module C is installed at the starting position of the multi-section equipment train and on top of the follow-up spray bracket of the equipment train. After a single intelligent spray cooling module C has been working for a period of time, the lowest temperature point in the long channel temperature curve obtained by data simulation calculation is used as the installation position of the next intelligent spray cooling module C, and the second intelligent spray cooling module C is installed; after two intelligent spray cooling modules C have been working at the same time for a period of time, the lowest temperature point in the long channel temperature curve obtained by data simulation calculation is used as the installation position of the next intelligent spray cooling module C, and the third intelligent spray cooling module C is installed. The Nth intelligent spray cooling module C is determined in the above manner until the spray cooling range of the Nth intelligent spray cooling module C covers the end position of the multi-section equipment train, thereby determining the initial spacing between the N intelligent spray cooling modules C;

[0048] Finally, N intelligent spray cooling modules C were used to perform synchronous spraying operations. The initial spacing between the N intelligent spray cooling modules C was verified using the temperature distribution signals collected in real time by a long continuous distributed optical fiber temperature detector, and the actual installation position was further adaptively adjusted.

[0049] d) For the rear channel area of ​​multiple follow-up equipment:

[0050] First, the wind speed signal D, temperature signal -D, and humidity signal D near the air inlet are collected in real time using the integrated receiving sensor D to obtain wind speed data D, temperature data -D, and humidity data D near the air inlet. The temperature signal D of the overall temperature distribution in the area is collected in real time using the long continuous distributed optical fiber temperature detector to obtain temperature distribution data D for the entire area. The cooling capacity required for spray cooling is calculated based on the wind speed data D, temperature data -D, and humidity data D near the air inlet, the overall temperature distribution data D for the entire area, and the set channel temperature and humidity data, thereby determining the required total number of high-pressure atomizing nozzles.

[0051] Then, the number of high-pressure atomizing nozzles is allocated according to the ratio of 3:2:1. Then, according to the allocation results, they are installed on the three intelligent spray cooling modules D of the first, second and third levels respectively. At the same time, the multiple high-pressure atomizing nozzles on each intelligent spray cooling module D are installed at equal intervals.

[0052] Next, determine the initial spacing between the three intelligent spray cooling modules D. Install the first-level intelligent spray cooling module D at the end of the multi-section equipment train and on top of the equipment train's follow-up spray bracket. After the first-level intelligent spray cooling module D has been operating for a period of time, the lowest temperature point in the long channel temperature curve obtained by data simulation calculation is used as the installation position for the second-level intelligent spray cooling module D, and the second-level intelligent spray cooling module D is installed. After the first-level and second-level intelligent spray cooling modules D have been operating simultaneously for a period of time, the lowest temperature point in the long channel temperature curve obtained by data simulation calculation is used as the installation position for the third-level intelligent spray cooling module D, and the third-level intelligent spray cooling module D is installed. This determines the initial spacing between the three intelligent spray cooling modules D.

[0053] Finally, three intelligent spray cooling modules D were used to perform synchronous spraying operations. The initial spacing between the three intelligent spray cooling modules D was verified using the temperature distribution signals collected in real time by a long continuous distributed optical fiber temperature detector, and the actual installation position was further adaptively adjusted.

During this process, a long continuous distributed optical fiber temperature detector is used to collect the temperature signal D of the overall temperature distribution of the area in real time, obtaining the overall temperature distribution data D of the area. The working effect of the three intelligent spray cooling modules D is tracked based on the overall temperature distribution data D of the area. At the same time, if the temperature distribution data D shows an abnormality, the spacing of the three intelligent spray cooling modules D and the spray parameters of each high-pressure atomizing nozzle are adjusted in a timely manner to ensure the expected cooling effect.

[0060] S36: After the test and adjustment are completed, ensure that the cooling system can operate stably in a working environment with long channels, high temperature airflow and multiple follow-up heat dissipation points, achieving precise cooling and maintaining work efficiency;

[0061] At the same time, monitor the operation of the waste heat recovery, storage and utilization system and the waste liquid treatment and recycling module to ensure the good effects of waste heat recovery and waste liquid treatment, and perform maintenance and adjustments as needed;

[0062] Step 4: Use the cooling system to perform cooling operations;

[0063] S41: Start the cooling system;

[0064] In work areas that require cooling, ensure that the cooling system has been correctly installed and is in normal operation;

[0065] S42: Setting temperature and humidity requirements;

[0066] According to the cooling requirements of different operating areas, use modular partition controllers A, B, C, and D to set the temperature and humidity requirements for the high-wall hot long channel area, the channel area in front of multiple follower equipment, the channel area in front of multiple follower equipment, and the channel area in the back of multiple follower equipment, respectively, to ensure that the cooling system performs cooling according to the expected conditions;

[0067] S43: Real-time monitoring of environmental parameters;

[0068] During the operation of the cooling system, the integrated receiving sensor A, the integrated receiving sensor B, the integrated receiving sensor C and the integrated receiving sensor D respectively collect the temperature signal 1, the humidity signal and the wind speed signal of the high-wall hot long channel area, the multi-follower device front channel area, the multi-follower device channel area and the multi-follower device rear channel area close to the air inlet side, and send them to the module partition controller A, the module partition controller B, the module partition controller C and the module partition controller D respectively. The module partition controller A, the module partition controller B, the module partition controller C and the module partition controller D analyze and process the received signals, and obtain the temperature data 1, the humidity data and the wind speed data of the corresponding channel area, and then send the temperature data 1, the humidity data and the wind speed data of the corresponding channel area to the main controller;

[0069] Synchronously, a long continuous distributed optical fiber temperature detector is used to collect temperature signal 2 of the overall temperature distribution of the long channel in real time, and sends it to the main controller. The main controller obtains temperature distribution data 2 of the entire long channel based on temperature signal 2, and sends them to module partition controller A, module partition controller B, module partition controller C and module partition controller D respectively. At the same time, the main controller displays the received temperature data 1, humidity data and wind speed data of the corresponding channel area and the obtained temperature distribution data 2 in real time through the monitoring interface, so as to realize real-time monitoring of the environmental parameters of each channel area and the temperature distribution of the entire long channel;

[0070] S44: Analyze monitoring data and obtain optimal spray parameters;

[0071] Utilize modular partition controller A, modular partition controller B, modular partition controller C, and modular partition controller D to calculate the cooling capacity required for spray cooling based on the temperature data 1, humidity data, and wind speed data of the corresponding channel area, the overall temperature distribution data 2 of the long channel, and the set channel temperature and humidity data, and further derive the optimal spray parameters and optimal spray spacing of the corresponding channel area;

[0072] S45: Automatically control the operation of the intelligent spray cooling module;

[0073] Module partition controller A, module partition controller B, module partition controller C, and module partition controller D send corresponding control signals to the three intelligent spray cooling modules A in the high-wall hot long channel temperature control module, the three intelligent spray cooling modules B in the three-stage temperature control module in front of the follower device, the N intelligent spray cooling modules C in the segmented long temperature control module of the follower device, and the three intelligent spray cooling modules D in the three-stage temperature control module behind the follower device based on the optimal spray parameters and optimal spray spacing of the corresponding channel area, so as to control the intelligent spray cooling modules A, intelligent spray cooling modules B, and intelligent spray cooling modules D to perform real-time spraying operations according to the set parameters to reduce the ambient temperature of the channel area;

[0074] During this process, multiple ranging laser radars on the high-pressure atomizing nozzle are used to conduct real-time detection of the vehicles and pedestrians below. When a vehicle or pedestrian is detected passing within the set range below the high-pressure atomizing nozzle, a vehicle or pedestrian approaching signal is sent to the module partition controller in the channel area. When a vehicle or pedestrian is detected leaving the set range, the vehicle or pedestrian approaching signal is stopped. After receiving the vehicle or pedestrian approaching signal, the corresponding module partition controller controls the high-pressure atomizing nozzle in the corresponding area to stop working until the vehicle or pedestrian approaching signal disappears and then restarts working.

[0075] S46: Perform precise cooling operations in each channel area;

[0076] The main controller sends control signals to the module partition controller A, module partition controller B, module partition controller C, and module partition controller D respectively through a graded stepped cooling method based on the obtained long channel overall temperature distribution data. After receiving the corresponding control signals, the module partition controller A, module partition controller B, module partition controller C, and module partition controller D respectively adjust and control the intelligent spray cooling module A, intelligent spray cooling module B, intelligent spray cooling module C, and intelligent spray cooling module D accordingly, so as to achieve uniform cooling operation for the high-wall hot long channel area and the channel area with multiple follower equipment, and achieve three-level stepped cooling operation for the channel area in front of the multiple follower equipment and the channel area behind the multiple follower equipment, so as to ensure the comfort of the staff in the corresponding channel area;

[0077] S47: Continuously monitor and adjust spray parameters during exercise;

[0078] During the operation of the cooling system, the environmental parameters and the overall temperature distribution of the long channel are continuously monitored through the monitoring interface of the main controller. When abnormal conditions occur or adjustments are required, the spray parameters are adjusted in a timely manner through the module partition controller A, module partition controller B, module partition controller C, and module partition controller D to ensure that the ambient temperature of the channel area is maintained within the set range;

[0079] S48: waste liquid treatment and waste heat recovery;

[0080] The waste heat recovery and storage system is used to recover and store waste heat generated in the equipment train and the environmental space, and the waste liquid treatment and recycling module is used to collect and store the falling spray liquid and purify the spray liquid;

[0081] S49: Cooling work is completed;

[0082] After the cooling operation is completed, shut down the cooling system in time and ensure that all parts stop running.

[0083] Furthermore, in order to facilitate real-time viewing of various parameters during the test adjustment process, real-time observation is performed through the monitoring interface of the main controller during the test adjustment process from S32 to S35 in step three.

[0084] As a preference, in step 2 S21, the spray parameters include spray liquid supply flow rate, spray liquid supply pressure, spray direction and spray angle.

[0085] This method uses data simulation to determine the number and spacing of high-pressure atomizing nozzles on individual intelligent spray cooling modules for high-walled, hot, and long corridors and those with multiple transport equipment. This makes the determination process more rational and scientific, helping to ensure effective cooling. Furthermore, by using data modules to obtain a long corridor temperature curve and determining the spacing of intelligent spray cooling modules based on the lowest temperature point in the temperature curve, it ensures that both high-walled, hot, and long corridors and those with multiple transport equipment achieve good cooling effects overall. For the aisle areas in front of and behind multiple follower devices, the required cooling capacity for spray cooling is first determined based on the environmental parameters of the aisle area, and the total number of high-pressure atomizing nozzles is then determined. These nozzles are then distributed in a 3:2:1 ratio and installed on the three-stage intelligent spray cooling modules. The spacing between the modules is then determined based on the temperature curve. This not only ensures cooling effects in the aisle areas in front of and behind multiple follower devices, but also facilitates a three-stage stepped cooling operation, thereby ensuring the comfort of workers in the corresponding aisle areas. During the test, for each channel area, the required spray cooling capacity is first calculated through the environmental parameters on the air inlet side combined with the temperature and humidity data set in the area, and then the optimal spray parameters and the optimal spray spacing are further obtained. The spray action of the intelligent spray cooling module in the area is controlled according to the optimal spray parameters and the optimal spray spacing, which can ensure that the cooling effect of the channel area is the most efficient. At the same time, the overall temperature distribution data is obtained by the signal collected by the long continuous distributed optical fiber temperature detector. The actual cooling effect of each channel area can be verified by tracking the cooling effect of the channel area. In this way, before the formal cooling operation is carried out, it can be ensured that each cooling part can operate normally and efficiently, ensuring the reliability of the cooling system. During the cooling process using the cooling system, the optimal spray parameters are determined based on environmental parameters obtained through real-time monitoring. The intelligent spray cooling module is then automatically controlled based on these optimal spray parameters, achieving fully automated operation of the cooling process. Simultaneously, multiple ranging laser radars on the high-pressure atomizing nozzles detect the presence of pedestrians and vehicles below in real time, enabling the spray to automatically stop when pedestrians or vehicles are present and automatically resume after they pass, further enhancing the intelligence of the cooling process. Furthermore, uniform cooling is achieved for high-walled, hot, and long channels and channels with multiple servo equipment, while a three-level stepped cooling system is implemented for channels in front of and behind multiple servo equipment, ensuring the comfort of personnel in the corresponding channel areas. This method has low implementation costs, low ventilation speed requirements, and ideal cooling effects. It can achieve long-distance, long-term temperature-controlled cooling operations and precisely control the cooling of each channel area without spraying an insulation layer on the rock wall.

[0127] The present invention also provides a cooling method for a long channel high temperature airflow with multiple follower heat dissipation points, which uses a cooling system for a long channel high temperature airflow with multiple follower heat dissipation points, including the following steps:

[0128] Step 1: Build the cooling system framework;

[0129] S11: For long tunnel conditions characterized by high wall heat and high ambient temperatures, the initial inlet air temperature exceeds the maximum required temperature. As ventilation distance increases, the inlet air exchanges energy more fully with the environment, causing the inlet air temperature to continue to rise. Under normal ventilation conditions for high-temperature long tunnels, comprehensive control of the temperature distribution in Long Tunnel 1 is required.

[0130] In the long channel 1, the temperature control areas that need to be cooled are determined in sequence from the side close to the air inlet to the direction away from the air inlet, including the high-wall hot long channel area where personnel work, the channel area in front of multiple follower equipment, the channel area of ​​multiple follower equipment, and the channel area behind multiple follower equipment;

[0131] S12: Arrange multiple retractable brackets in sequence along the length direction of the long channel 1 in the high-wall hot long channel area, and use the multiple retractable brackets to form a fixed spray bracket;

In this process, multiple ranging laser radars (2213) on the high-pressure atomizing nozzle (221) are used to perform real-time detection of the vehicles and pedestrians below. When a vehicle or pedestrian is detected passing within a set range below the high-pressure atomizing nozzle (221), a vehicle or pedestrian approaching signal is sent to the module partition controller of the channel area. When a vehicle or pedestrian is detected leaving the set range, the vehicle or pedestrian approaching signal is stopped. After receiving the vehicle or pedestrian approaching signal, the corresponding module partition controller controls the high-pressure atomizing nozzle (221) within the corresponding area to stop working and restart the work after the vehicle or pedestrian approaching signal disappears.
