[0002] During blasting operations, the explosion of explosives will produce a large amount of toxic and harmful gases and carry a large amount of particulate dust, which greatly deteriorates the working environment and causes poisoning accidents, seriously restricting the safe production of enterprises. The reaction of explosives is incomplete during explosion, and the toxic and harmful gaseous products during blasting are mainly CO gas, which is colorless and odorless, and extremely toxic. It is very easy to cause casualties when the concentration is high. In particular, the environment where blasting operations are located is generally a small space, and the relative humidity of the environment is relatively high, the ventilation conditions on site are poor, and high-concentration CO is difficult to handle, and CO poisoning accidents are very likely to occur. At present, the blasting workplace mainly uses local mechanical ventilation to dilute high-concentration CO. When the effect of mechanical ventilation is affected by a series of factors such as the inclination angle of the tunnel, the ventilation distance, and the ventilation position, and at the same time, because the density of CO is close to the density of air, ventilation cannot guarantee a good dilution effect. In addition, there is also the use of elimination solution to absorb CO gas, but this method basically brings potential dangers and affects the overall environmental safety. Therefore, it is necessary to provide an elimination system and method that can efficiently eliminate CO in the tunnel airflow to reduce the hazards of high-concentration CO to a certain extent and ensure the safety of personnel.

[0011] Furthermore, in order to ensure good air tightness at the connection position, flame retardant sealing gaskets are arranged around the connection between the first dehumidification unit and the second dehumidification unit and around the connection between the second dehumidification unit and the third dehumidification unit.

[0012] In the present invention, a flow equalizer is provided in the smoke filter cabin, which can effectively change the speed and direction of the incoming airflow, so that the airflow can flow through the particle filter device and the air dehumidification module more evenly. On the one hand, each part of the filter mesh body and each part of the air dehumidification module can be fully utilized, so that the dust particles in the airflow can be filtered out more efficiently and the airflow can be dried more efficiently. On the other hand, the resistance of the airflow can be effectively reduced, so as to ensure the elimination efficiency of CO. For the particle filter device, the active reel is used to cooperate with the driven reel to carry out the winding action of the filter mesh body, and the different sections of the filter mesh body can be adjusted online. In this way, an unused section of the filter mesh body can be adjusted to the dust removal operation position in time, effectively ensuring the filtering effect of the dust particles in the airflow. A dust collection chamber is provided at the bottom of the cabin body corresponding to the position of the particle filter device, which can facilitate the collection of dust particles falling off the filter mesh body. The air dehumidification module is composed of three dehumidification units adjacent to each other in sequence, which can effectively ensure the drying effect. A gas sensor and a first CO sensor are arranged on the air inlet side of the smoke filter cabin, so that the gas concentration data and CO concentration data 1 on the air inlet side can be obtained in real time. In this way, not only can an alarm action be given in time when the gas concentration exceeds the standard, but also the concentration of CO in the airflow on the air inlet side can be understood in time, so as to determine whether it is necessary to perform CO elimination operations on the current airflow. A second CO sensor is arranged on the air outlet side of the smoke filter cabin, so that it is convenient to obtain CO concentration data 2 on the air outlet side in real time. In this way, it can be combined with CO concentration data 1 on the air inlet side to further determine whether the current airflow needs to perform CO elimination operations. On the basis of the first air inlet being opened at the left end of the smoke filter cabin, a second air inlet is opened at the upper left end of the smoke filter cabin at the same time, so that the two air inlets can be used to introduce airflow at the same time, which is conducive to ensuring the air flow rate of the incoming air, so that the demand for efficient CO elimination can be met. A first air outlet is provided at the upper part of the right end of the smoke filter cabin, and a first air volume control valve and a first exhaust fan are installed therein, so that the opening and closing of the first air outlet can be conveniently controlled by the first air volume control valve, and at the same time, the first exhaust fan can be used to provide negative pressure for drainage to the outside, so that when CO concentration data 1 and 2 are both low and no CO elimination treatment is required, the first air volume control valve can be directly opened, and the first exhaust fan can be controlled to start, so that the airflow after the filtration and drying treatment can be directly drained to the outside of the smoke filter cabin, thereby avoiding the waste of CO elimination resources. The multi-stage CO elimination cabin is isolated into an airflow circulation chamber and a CO elimination chamber distributed up and down by a partition, and at the same time, a front circulation air outlet and a rear circulation air outlet are respectively opened at the front and rear of the partition, so that the CO elimination chamber can be conveniently used as the main chamber for CO elimination operation, and the airflow circulation chamber can be used as an auxiliary chamber to provide a circulation path.A plurality of guide plates are installed in the front circulation air outlet, a second air volume control valve is installed in the rear circulation air outlet, and a second exhaust fan is installed in the air circulation chamber, so that the airflow can circulate through the air circulation chamber and the CO elimination chamber when the second air volume control valve is opened and the second exhaust fan is started. In this way, when the elimination effect of the airflow through the CO elimination chamber is not ideal after the airflow flows through the CO elimination chamber once, the airflow can be made to pass through the multi-stage CO elimination assembly multiple times by circulating flow, thereby effectively improving the CO elimination effect. A bottom track is arranged at the bottom of the CO elimination chamber, and a primary elimination member and a secondary elimination member are slidably assembled on the left and right parts of the bottom track respectively. At the same time, a rotating elimination member is arranged between the primary and secondary elimination members, so that the triple purification operation of CO can be achieved through the primary elimination member, the rotating elimination member and the secondary elimination member, so as to effectively improve the CO elimination effect and efficiency. On this basis, the three gears on the three rotating components interact with the first and second elimination parts through three pairs of racks, so that the three rotating parts can be driven to rotate through the relative or opposite movement between the first and second elimination parts, and then the rotational movement can be used to form a gas disturbance space with disturbed airflow between the first and second elimination parts, which is conducive to prolonging the time for the airflow to pass through the multi-stage CO elimination component, so that the passing airflow can fully contact the CO elimination layer coated on each elimination part, which is conducive to a more sufficient catalytic oxidation reaction, so as to effectively improve the elimination effect and efficiency of CO. The telescopic drive mechanism located on the air outlet side is connected to the secondary elimination part, so that the linear electric push rod can be used to automatically drive the secondary elimination part to reciprocate, and then the first elimination part can be synchronously driven to reciprocate, and the three rotating components in the rotating elimination part can be driven to rotate. By arranging a third CO sensor on the air outlet side of the multi-stage CO elimination cabin, it is convenient to obtain CO concentration data three in real time. In this way, the elimination effect of CO in the current airflow can be judged according to the CO concentration data three, and then the elimination effect can be improved in time by a cyclic CO elimination operation when the CO elimination effect is poor, so as to achieve the purpose of effectively eliminating CO. A heating component and a temperature sensor are installed in the airflow circulation chamber. When the elimination ability of the CO elimination coating in each elimination part is weakened, the heating component can be used to heat the circulating airflow to form a high-temperature airflow, and then the high-temperature airflow is used to activate and regenerate the CO elimination coating on each elimination part, so as to achieve the purpose of reusing each elimination part. By installing a fan in the drainage device, it is convenient to use the fan to provide drainage negative pressure, and the size of the drainage negative pressure can be controlled by controlling the fan power. In this way, a controllable traction power can be provided for the airflow to pass through the smoke filter dehumidification cabin and the multi-stage CO elimination cabin, which is conducive to ensuring the continuity, controllability and stability during the CO elimination operation.

[0013] The present invention realizes negative pressure control through the drainage device, attracts smoke airflow into the elimination system, and then undergoes particle filtration and dehumidification treatment, realizes triple purification of airflow through the primary elimination component, the rotating elimination component and the secondary elimination component, and can realize continuous CO elimination operation. The system has a reasonable structure, low resistance and high efficiency, flexible and controllable CO elimination process, and ideal CO elimination effect. It can realize multi-stage elimination of toxic and harmful CO gases in blasting operations, can significantly improve elimination efficiency, and can ensure the life, health and safety of construction personnel by improving the air quality of the construction environment.

[0014] The present invention also provides a multi-channel multi-stage cycle CO elimination method, which uses a multi-channel multi-stage cycle CO elimination system, comprising the following steps: Step 1: Assembly of the multi-channel multi-stage cycle CO elimination system and adjustment of the operating position; S11: The smoke filtration and dehumidification cabin, the multi-stage CO elimination cabin and the drainage device are sealed and connected in sequence, and an automatic lifting platform is installed at the bottom of the multi-stage CO elimination cabin to form a multi-channel multi-stage circulation CO elimination system; S12: Perform an airflow tightness test on the multi-channel multi-stage circulation CO elimination system for a set test time to test the overall air tightness of the multi-channel multi-stage circulation CO elimination system. After the air tightness meets the requirements, execute S13; S13: Move the multi-channel multi-stage circulation CO elimination system to the designated elimination position in the tunnel where the blasting operation is to be carried out, and fix the position of the traveling wheels to prevent shaking or movement during the elimination operation; S14: Determine the elimination operation level according to the cross-sectional height of the tunnel, then control the lifting hydraulic cylinder to perform telescopic action, and lift the smoke filter dehumidification cabin, the multi-stage CO elimination cabin and the drainage device to the predetermined elimination operation level through the scissor lift frame; Step 2: CO elimination operation; Maintain the closed state of the first air volume control valve and the second air volume control valve, and maintain the closed state of the second air volume control valve and the second exhaust fan; set the time before the blasting operation begins, control the fan to start working, use the fan to provide drainage negative pressure, and at the same time, synchronously control multiple linear electric push rods to slowly perform periodic reciprocating telescopic movements, drive the secondary elimination member to reciprocate in the left and right directions, and drive the three rotating components in the rotating elimination member to perform reciprocating rotation through paired racks, and synchronously drive the primary elimination member to reciprocate in the left and right directions, so as to form a gas disturbance space between the primary elimination member and the secondary elimination member, where the disturbance force is weaker than the drainage negative pressure; At the same time, the gas concentration signal in the airflow before dehumidification is collected in real time by the gas sensor and sent to the controller; the CO concentration signal 1 in the airflow before dehumidification is collected in real time by the first CO sensor and sent to the controller; the controller obtains the gas concentration data and CO concentration data 1 of the airflow before dehumidification according to the gas concentration signal and the CO concentration signal 1 respectively; After the blasting operation begins, the airflow is forced to enter the smoke filter dehumidification chamber through the first air inlet by the effect of drainage negative pressure, and then pass through the flow equalizer, the particle filter and the air dehumidification module in sequence. In this process, the flow equalizer is used to change the speed and direction of the airflow, so that the airflow passes through the particle filter evenly, and the filter mesh is used to filter out dust particles in the airflow, and the air dehumidification module is used to dry the airflow; At the same time, the second CO sensor collects the CO concentration signal 2 in the dehumidified airflow in real time and sends it to the controller, and the controller obtains the CO concentration data 2 of the dehumidified airflow according to the CO concentration signal 2; The controller compares the CO concentration data 1 and the CO concentration data 2 with the CO treatment lower limit threshold. When the CO concentration data 1 and the CO concentration data 2 are both lower than the CO treatment lower limit threshold, it is determined that the current airflow does not need to be treated with CO elimination, and the first air volume control valve is directly controlled to open, and the first exhaust fan is controlled to start working. The first exhaust fan is used to provide negative pressure, and the dried airflow is directly guided to the outside of the smoke filter dehumidification cabin through the first air outlet until the CO concentration data 1 is higher than or equal to the CO treatment lower limit threshold. The first air volume control valve is controlled to close, and the first exhaust fan is controlled to stop, so that the airflow after drying is The airflow continues to pass through the multi-stage CO elimination component. In this process, the airflow enters the gas disturbance space through several flow channels 1 inside the first-stage elimination component, changes the flow trajectory under the disturbance of the three rotating components to effectively extend the time of passing through the gas disturbance space, and then flows out through several flow channels 2 inside the second-stage elimination component. Synchronously, the CO elimination coatings on several flow channels 1, the CO elimination coatings on multiple elimination fan blades, and the CO elimination coatings on several flow channels 2 are used in turn to perform triple catalytic oxidation treatment on the CO in contact with the airflow, so as to achieve efficient elimination of CO in the airflow; At the same time, the third CO sensor collects the CO concentration signal 3 of the airflow after the CO elimination process in real time and sends it to the controller. The controller obtains the CO concentration data 3 according to the CO concentration signal 3, and compares the CO concentration data 3 with the CO safety concentration threshold in real time. When the CO concentration data 3 is higher than the CO safety concentration threshold, the second air volume control valve is controlled to open, the second exhaust fan is controlled to start working, the power of the fan is controlled to be reduced, and the heating component is kept powered off. The second exhaust fan is used to provide negative pressure, and the airflow in the CO elimination chamber is guided to the airflow circulation chamber through the rear circulation air port, and discharged to the inlet side of the first-stage elimination component through multiple guide plates, so that the airflow passes through the multi-stage CO elimination component again, and the cyclic CO elimination operation is performed in a cyclic manner by using the airflow circulation. When the CO concentration data 3 is lower than or equal to the CO safety concentration threshold, the second air volume control valve is controlled to close, the second exhaust fan is controlled to stop, and the power of the fan is controlled to restore to the normal elimination operation state, so that the airflow is discharged to the outside through the second air outlet. When the cyclic CO elimination operation is continued to the set cycle time, the CO concentration data 3 is still higher than the CO safety concentration threshold, then step 3 is directly executed; Step 3: Eliminate performance cycle regeneration; The fan is controlled to stop, and at the same time, the second air volume control valve is controlled to open and the heating component is controlled to be powered on. At the same time, the temperature signal of the heating component is collected in real time through the temperature sensor and sent to the controller. The controller obtains temperature data according to the temperature signal and compares the temperature data with the activation temperature threshold. When the temperature data is higher than or equal to the activation temperature threshold, the second exhaust fan is controlled to start working, and the second exhaust fan is used to provide negative pressure to introduce the airflow in the CO elimination chamber into the airflow circulation chamber, and the heating component is used to heat the airflow to form a high-temperature airflow, and then the high-temperature airflow is discharged to the inlet side of the first-level elimination component through a plurality of guide plates, so that the high-temperature airflow passes through a plurality of flow channels 1 in the first-level elimination component, a plurality of elimination fan blades on the rotating component, and a plurality of flow channels 2 in the second-level elimination component in sequence, and the CO elimination coating in the flow channel 1, the CO elimination coating on the elimination fan blade, and the CO elimination coating in the flow channel 2 are activated by the high-temperature airflow, and the CO elimination coating is activated and regenerated by circulating the high-temperature airflow. After the activation and regeneration process continues until the set activation time, step 2 is re-executed to continue the CO elimination operation.

[0015] Furthermore, in order to facilitate the rapid shedding of dust particles attached to the filter mesh body by means of vibration, in step 2, after the CO elimination operation continues for a set elimination time, the vibrator is controlled to start working for a set time, and drives the filter section of the filter mesh body to vibrate, so that the dust particles attached to the filter mesh body fall off by means of vibration and fall into the dust collecting chamber; after the vibrator stops working, the drive motor is controlled to start working to drive the active reel to rotate a set angle, so that a used section of the filter mesh body is wound on the active reel, and an unused section of the filter mesh body is placed between the active reel and the driven reel.

[0016] The present invention proposes a method of using chemical coating catalytic coating, wherein the catalytic coating for CO elimination is coated on several flow channel one surfaces on the primary elimination member, several flow channel two surfaces on the secondary elimination member, and multiple elimination fan blade surfaces on the rotating assembly, so that the elimination effect and elimination efficiency of CO in the airflow can be effectively improved by triple elimination when the airflow passes through. At the same time, in the CO elimination process, a linear electric push rod is used to provide driving force for the secondary elimination member, and a pair of matching racks and a gear meshed with the paired racks are used to drive the primary elimination member to move back and forth and drive multiple rotating assemblies to rotate, so that a gas disturbance space can be formed between the primary elimination member and the secondary elimination member, which is conducive to changing the direction of the airflow by disturbance, so that the airflow can better contact with the CO elimination coating on the flow channel one at each position, the CO elimination coating on the flow channel two at each position, and the CO elimination coating on each elimination fan blade, and the airflow passing time can be effectively extended, so that the elimination effect of CO in the airflow can be significantly improved. By using the flow equalizer to change the speed and direction of the airflow, the airflow can pass through the particle filter and the air dehumidification module evenly, which can not only make full use of all parts on the particle filter and the air dehumidification module, but also effectively reduce wind resistance, which is conducive to ensuring the CO elimination efficiency. For the airflow flowing through the smoke filter dehumidification cabin, the CO concentration data 1 on the air inlet side and the CO concentration data 2 on the air outlet side are compared with the CO processing lower limit threshold, which can facilitate the judgment of whether the CO concentration in the current airflow is high. When the CO concentration in the current airflow is low, the first air volume control valve is directly opened and the first exhaust fan is started, and the filtered and dried airflow can be directly guided to the outside of the smoke filter dehumidification cabin through the first air outlet. This is conducive to avoiding the waste of CO elimination resources and significantly improving the flexibility and intelligence of the CO elimination operation. For the airflow passing through the outlet side of the multi-stage CO elimination chamber, by comparing the CO concentration data 3 and the CO safety concentration threshold, the current CO elimination effect can be effectively monitored. When the CO concentration data 3 of the airflow passing through the multi-stage CO elimination chamber for a single time is high, the airflow can be circulated multiple times in the CO elimination chamber and the airflow circulation chamber when the second air volume control valve is opened and the second exhaust fan is started, and then the cyclic CO elimination operation can be performed by airflow circulation to effectively ensure the elimination effect of CO. When the elimination effect of CO still cannot be improved by airflow circulation, the fan is turned off, and the circulating airflow is heated by the heating component to form a high-temperature airflow, and then the high-temperature airflow is used to realize the activation and regeneration of each elimination component, which can realize the desorption effect of toxic substances on the flow channel surface and the elimination fan surface in the elimination component, and effectively improve the regeneration level of the elimination performance of each elimination component, so as to achieve the effect of repeated use of the elimination component.

[0017] The method has the advantages of simple implementation process, high intelligence, good safety performance, and the ability to continuously eliminate CO. It can efficiently eliminate the CO generated during the blasting process and can simultaneously remove some dust particles in the airflow, which is beneficial to reducing the degree of environmental pollution caused by blasting operations.

[0030] In order to improve the flow balancing effect of the airflow and to effectively reduce the cost, the flow balancing plate 7 has a honeycomb structure and is made of flame-retardant plastic material with a thickness of 3 to 6 cm.

[0031] In order to prevent large particles from entering the elimination system and causing blockage or reducing the CO elimination effect, the first air inlet 5 is located in the central area of ​​the left end of the cabin body 4, and its cross-section is square. A stainless steel protective filter is installed inside the first air inlet 5, and the stainless steel protective filter is used to prevent large particles from entering the interior of the smoke filtering and dehumidification cabin 1; the second air inlet 6 is rectangular.

[0032] In order to ensure good air tightness at the connection position, flame retardant sealing gaskets are provided around the connection between the first dehumidification unit 17 and the second dehumidification unit 18 and around the connection between the second dehumidification unit 18 and the third dehumidification unit 19.

[0033] In the present invention, a flow equalizer is provided in the smoke filter cabin, which can effectively change the speed and direction of the incoming airflow, so that the airflow can flow through the particle filter device and the air dehumidification module more evenly. On the one hand, each part of the filter mesh body and each part of the air dehumidification module can be fully utilized, so that the dust particles in the airflow can be filtered out more efficiently and the airflow can be dried more efficiently. On the other hand, the resistance of the airflow can be effectively reduced, so as to ensure the elimination efficiency of CO. For the particle filter device, the active reel is used to cooperate with the driven reel to carry out the winding action of the filter mesh body, and the different sections of the filter mesh body can be adjusted online. In this way, an unused section of the filter mesh body can be adjusted to the dust removal operation position in time, effectively ensuring the filtering effect of the dust particles in the airflow. A dust collection chamber is provided at the bottom of the cabin body corresponding to the position of the particle filter device, which can facilitate the collection of dust particles falling off the filter mesh body. The air dehumidification module is composed of three dehumidification units adjacent to each other in sequence, which can effectively ensure the drying effect. A gas sensor and a first CO sensor are arranged on the air inlet side of the smoke filter cabin, so that the gas concentration data and CO concentration data 1 on the air inlet side can be obtained in real time. In this way, not only can an alarm action be given in time when the gas concentration exceeds the standard, but also the concentration of CO in the airflow on the air inlet side can be understood in time, so as to determine whether it is necessary to perform CO elimination operations on the current airflow. A second CO sensor is arranged on the air outlet side of the smoke filter cabin, so that it is convenient to obtain CO concentration data 2 on the air outlet side in real time. In this way, it can be combined with CO concentration data 1 on the air inlet side to further determine whether the current airflow needs to perform CO elimination operations. On the basis of the first air inlet being opened at the left end of the smoke filter cabin, a second air inlet is opened at the upper left end of the smoke filter cabin at the same time, so that the two air inlets can be used to introduce airflow at the same time, which is conducive to ensuring the air flow rate of the incoming air, so that the demand for efficient CO elimination can be met. A first air outlet is provided at the upper part of the right end of the smoke filter cabin, and a first air volume control valve and a first exhaust fan are installed therein, so that the opening and closing of the first air outlet can be conveniently controlled by the first air volume control valve, and at the same time, the first exhaust fan can be used to provide negative pressure for drainage to the outside, so that when CO concentration data 1 and 2 are both low and no CO elimination treatment is required, the first air volume control valve can be directly opened, and the first exhaust fan can be controlled to start, so that the airflow after the filtration and drying treatment can be directly drained to the outside of the smoke filter cabin, thereby avoiding the waste of CO elimination resources. The multi-stage CO elimination cabin is isolated into an airflow circulation chamber and a CO elimination chamber distributed up and down by a partition, and at the same time, a front circulation air outlet and a rear circulation air outlet are respectively opened at the front and rear of the partition, so that the CO elimination chamber can be conveniently used as the main chamber for CO elimination operation, and the airflow circulation chamber can be used as an auxiliary chamber to provide a circulation path.A plurality of guide plates are installed in the front circulation air outlet, a second air volume control valve is installed in the rear circulation air outlet, and a second exhaust fan is installed in the air circulation chamber, so that the airflow can circulate through the air circulation chamber and the CO elimination chamber when the second air volume control valve is opened and the second exhaust fan is started. In this way, when the elimination effect of the airflow through the CO elimination chamber is not ideal after the airflow flows through the CO elimination chamber once, the airflow can be made to pass through the multi-stage CO elimination assembly multiple times by circulating flow, thereby effectively improving the CO elimination effect. A bottom track is arranged at the bottom of the CO elimination chamber, and a primary elimination member and a secondary elimination member are slidably assembled on the left and right parts of the bottom track respectively. At the same time, a rotating elimination member is arranged between the primary and secondary elimination members, so that the triple purification operation of CO can be achieved through the primary elimination member, the rotating elimination member and the secondary elimination member, so as to effectively improve the CO elimination effect and efficiency. On this basis, the three gears on the three rotating components interact with the first and second elimination parts through three pairs of racks, so that the three rotating parts can be driven to rotate through the relative or opposite movement between the first and second elimination parts, and then the rotational movement can be used to form a gas disturbance space with disturbed airflow between the first and second elimination parts, which is conducive to prolonging the time for the airflow to pass through the multi-stage CO elimination component, so that the passing airflow can fully contact the CO elimination layer coated on each elimination part, which is conducive to a more sufficient catalytic oxidation reaction, so as to effectively improve the elimination effect and efficiency of CO. The telescopic drive mechanism located on the air outlet side is connected to the secondary elimination part, so that the linear electric push rod can be used to automatically drive the secondary elimination part to reciprocate, and then the first elimination part can be synchronously driven to reciprocate, and the three rotating components in the rotating elimination part can be driven to rotate. By arranging a third CO sensor on the air outlet side of the multi-stage CO elimination cabin, it is convenient to obtain CO concentration data three in real time. In this way, the elimination effect of CO in the current airflow can be judged according to the CO concentration data three, and then the elimination effect can be improved in time by a cyclic CO elimination operation when the CO elimination effect is poor, so as to achieve the purpose of effectively eliminating CO. A heating component and a temperature sensor are installed in the airflow circulation chamber. When the elimination ability of the CO elimination coating in each elimination part is weakened, the heating component can be used to heat the circulating airflow to form a high-temperature airflow, and then the high-temperature airflow is used to activate and regenerate the CO elimination coating on each elimination part, so as to achieve the purpose of reusing each elimination part. By installing a fan in the drainage device, it is convenient to use the fan to provide drainage negative pressure, and the size of the drainage negative pressure can be controlled by controlling the fan power. In this way, a controllable traction power can be provided for the airflow to pass through the smoke filter dehumidification cabin and the multi-stage CO elimination cabin, which is conducive to ensuring the continuity, controllability and stability during the CO elimination operation.

[0034] The present invention realizes negative pressure control through the drainage device, attracts smoke airflow into the elimination system, and then undergoes particle filtration and dehumidification treatment, realizes triple purification of airflow through the primary elimination component, the rotating elimination component and the secondary elimination component, and can realize continuous CO elimination operation. The system has a reasonable structure, low resistance and high efficiency, flexible and controllable CO elimination process, and ideal CO elimination effect. It can realize multi-stage elimination of toxic and harmful CO gases in blasting operations, can significantly improve elimination efficiency, and can ensure the life, health and safety of construction personnel by improving the air quality of the construction environment.

[0035] like Fig.14 As shown, the present invention also provides a multi-channel multi-stage cycle CO elimination method, using a multi-channel multi-stage cycle CO elimination system, including the following steps: Step 1: Assembly of the multi-channel multi-stage cycle CO elimination system and adjustment of the operating position; S11: The smoke filtering and dehumidifying cabin 1, the multi-stage CO elimination cabin 2 and the drainage device 3 are sealed and connected in sequence, and an automatic lifting platform 55 is installed at the bottom of the multi-stage CO elimination cabin 2 to form a multi-channel multi-stage circulation CO elimination system; S12: Perform an airflow tightness test on the multi-channel multi-stage circulation CO elimination system for a set test time to test the overall air tightness of the multi-channel multi-stage circulation CO elimination system. After the air tightness meets the requirements, execute S13; S13: The multi-channel multi-stage circulation CO elimination system is moved to the designated elimination position in the tunnel 64 where the blasting operation is to be performed, and the travel wheels 58 are fixed in position to prevent shaking or movement during the elimination operation; S14: Determine the elimination operation level according to the cross-sectional height of the tunnel 64, then control the lifting hydraulic cylinder to perform telescopic action, and lift the smoke filter dehumidification cabin 1, the multi-stage CO elimination cabin 2 and the drainage device 3 to the predetermined elimination operation level through the scissor lift 56; Step 2: CO elimination operation; Keep the first air volume control valve 22 and the second air volume control valve 29 in a closed state, and keep the second air volume control valve 29 and the second exhaust fan 32 in a closed state; set a time before the blasting operation starts, control the fan 51 to start working, use the fan 51 to provide drainage negative pressure, and at the same time, synchronously control multiple linear electric push rods 500 to slowly perform periodic reciprocating telescopic movements, drive the secondary elimination member 35 to reciprocate in the left and right directions, and drive the three rotating components 42 in the rotating elimination member 36 to perform reciprocating rotation through the paired racks 43, and synchronously drive the primary elimination member 34 to reciprocate in the left and right directions, so as to form a gas disturbance space between the primary elimination member 34 and the secondary elimination member 35, where the disturbance force is weaker than the drainage negative pressure; At the same time, the gas concentration signal in the airflow before dehumidification is collected in real time by the gas sensor 8, and is sent to the controller; the CO concentration signal 1 in the airflow before dehumidification is collected in real time by the first CO sensor 9, and is sent to the controller; the controller obtains the gas concentration data and CO concentration data 1 of the airflow before dehumidification according to the gas concentration signal and the CO concentration signal 1 respectively; After the blasting operation begins, the airflow is caused to enter the smoke filter dehumidification chamber 1 through the first air inlet 5 by the effect of drainage negative pressure, and then pass through the flow equalizer 7, the particle filter 11 and the air dehumidification module 13 in sequence. In this process, the flow equalizer 7 is used to change the speed and direction of the airflow, so that the airflow passes through the particle filter 11 evenly, and the filter mesh 16 is used to filter out dust particles in the airflow, and the air dehumidification module 13 is used to dry the airflow; At the same time, the second CO sensor 20 collects the CO concentration signal 2 in the dehumidified airflow in real time and sends it to the controller, and the controller obtains the CO concentration data 2 of the dehumidified airflow according to the CO concentration signal 2; The controller compares the CO concentration data 1 and the CO concentration data 2 with the CO treatment lower limit threshold. When the CO concentration data 1 and the CO concentration data 2 are both lower than the CO treatment lower limit threshold, it is determined that the current airflow does not need to be subjected to CO elimination treatment, and directly controls the first air volume control valve 22 to open, controls the first exhaust fan 21 to start working, and uses the first exhaust fan 21 to provide negative pressure to directly guide the dried airflow through the first air outlet 10 to the outside of the smoke filter dehumidification cabin 1, until the CO concentration data 1 is higher than or equal to the CO treatment lower limit threshold, controls the first air volume control valve 22 to close, controls the first exhaust fan 21 to stop, and makes the dried airflow The airflow continues to pass through the multi-stage CO elimination component 27. During this process, the airflow enters the gas disturbance space through the plurality of flow channels 1 62 inside the first-stage elimination component 34, changes the flow trajectory under the disturbance of the three rotating components 42 to effectively extend the time of passing through the gas disturbance space, and then flows out through the plurality of flow channels 2 63 inside the second-stage elimination component 35. Synchronously, the CO elimination coatings on the plurality of flow channels 1 62, the CO elimination coatings on the plurality of elimination fan blades 45, and the CO elimination coatings on the plurality of flow channels 2 63 are sequentially used to perform triple catalytic oxidation treatment on the CO in contact with the airflow, so as to achieve efficient elimination of CO in the airflow; At the same time, the third CO sensor 33 collects the CO concentration signal 3 of the airflow after the CO elimination process in real time and sends it to the controller. The controller obtains the CO concentration data 3 according to the CO concentration signal 3, and compares the CO concentration data 3 with the CO safety concentration threshold in real time. When the CO concentration data 3 is higher than the CO safety concentration threshold, the second air volume control valve 29 is controlled to open, the second exhaust fan 32 is controlled to start working, the power of the fan 51 is controlled to be reduced, and the heating component 30 is kept in a powered-off state. The second exhaust fan 32 is used to provide negative pressure to guide the airflow in the CO elimination chamber 26 through the rear circulation air outlet to the air circulation system. The air is discharged to the inlet side of the first-stage elimination component 34 through the plurality of guide plates 28, so that the airflow passes through the multi-stage CO elimination component 27 again, so as to perform a cyclic CO elimination operation in a cyclic manner by using airflow circulation, and when the CO concentration data 3 is lower than or equal to the CO safety concentration threshold, the second air volume control valve 29 is controlled to be closed, the second exhaust fan 32 is controlled to be stopped, and the power of the fan 51 is controlled to be restored to a normal elimination operation state, so that the airflow is discharged to the outside through the second air outlet 54. When the cyclic CO elimination operation is continued to the set cycle time, if the CO concentration data 3 is still higher than the CO safety concentration threshold, step 3 is directly executed; Step 3: Eliminate performance cycle regeneration; The fan 51 is controlled to stop, and at the same time, the second air volume control valve 29 is controlled to open and the heating component 30 is controlled to be powered on. At the same time, the temperature signal of the heating component 30 is collected in real time through the temperature sensor 31 and sent to the controller. The controller obtains temperature data according to the temperature signal and compares the temperature data with the activation temperature threshold. When the temperature data is higher than or equal to the activation temperature threshold, the second exhaust fan 32 is controlled to start working, and the second exhaust fan 32 is used to provide negative pressure to introduce the airflow in the CO elimination chamber 26 into the airflow circulation chamber 25, and the heating component 30 is used to heat the airflow to form a high-temperature airflow, and then the airflow is heated by the multiple induction blocks. The flow plate 28 discharges the high-temperature airflow to the inlet side of the first-stage elimination component 34, so that the high-temperature airflow passes through the several flow channels 1 62 in the first-stage elimination component 34, the multiple elimination fan blades 45 on the rotating component 42, and the several flow channels 2 63 in the secondary elimination component 35 in sequence, and the high-temperature airflow is used to activate the CO elimination coating in the flow channel 1 62, the CO elimination coating on the elimination fan blade 45, and the CO elimination coating in the flow channel 2 63, so that the CO elimination coating is activated and regenerated in a high-temperature airflow circulation manner. After the activation and regeneration process continues until the set activation time, step 2 is re-executed to continue the CO elimination operation.

[0036] In order to facilitate the rapid shedding of dust particles attached to the filter mesh by means of vibration, in step 2, after the CO elimination operation continues for a set elimination time, the vibrator 61 is controlled to start working for a set time, and drives the filter section of the filter mesh 16 to vibrate, so that the dust particles attached to the filter mesh 16 fall off by means of vibration and fall into the dust collecting chamber 12; after the vibrator 61 stops working, the drive motor is controlled to start working to drive the active reel 14 to rotate a set angle, so that a used section of the filter mesh 16 is wound on the active reel 14, and an unused section of the filter mesh 16 is placed between the active reel 14 and the driven reel 15.

[0037] As a preferred embodiment, in step 2, during the operation of the fan 51, the rotation speed of the fan 51 is adjusted to adjust the induced air volume, thereby maintaining a good CO elimination effect.

[0038] The present invention proposes a method of using chemical coating catalytic coating, wherein the catalytic coating for CO elimination is coated on several flow channel one surfaces on the primary elimination member, several flow channel two surfaces on the secondary elimination member, and multiple elimination fan blade surfaces on the rotating assembly, so that the elimination effect and elimination efficiency of CO in the airflow can be effectively improved by triple elimination when the airflow passes through. At the same time, in the CO elimination process, a linear electric push rod is used to provide driving force for the secondary elimination member, and a pair of matching racks and a gear meshed with the paired racks are used to drive the primary elimination member to move back and forth and drive multiple rotating assemblies to rotate, so that a gas disturbance space can be formed between the primary elimination member and the secondary elimination member, which is conducive to changing the direction of the airflow by disturbance, so that the airflow can better contact with the CO elimination coating on the flow channel one at each position, the CO elimination coating on the flow channel two at each position, and the CO elimination coating on each elimination fan blade, and the airflow passing time can be effectively extended, so that the elimination effect of CO in the airflow can be significantly improved. By using the flow equalizer to change the speed and direction of the airflow, the airflow can pass through the particle filter and the air dehumidification module evenly, which can not only make full use of all parts on the particle filter and the air dehumidification module, but also effectively reduce wind resistance, which is conducive to ensuring the CO elimination efficiency. For the airflow flowing through the smoke filter dehumidification cabin, the CO concentration data 1 on the air inlet side and the CO concentration data 2 on the air outlet side are compared with the CO processing lower limit threshold, which can facilitate the judgment of whether the CO concentration in the current airflow is high. When the CO concentration in the current airflow is low, the first air volume control valve is directly opened and the first exhaust fan is started, and the filtered and dried airflow can be directly guided to the outside of the smoke filter dehumidification cabin through the first air outlet. This is conducive to avoiding the waste of CO elimination resources and significantly improving the flexibility and intelligence of the CO elimination operation. For the airflow passing through the outlet side of the multi-stage CO elimination chamber, by comparing the CO concentration data 3 and the CO safety concentration threshold, the current CO elimination effect can be effectively monitored. When the CO concentration data 3 of the airflow passing through the multi-stage CO elimination chamber for a single time is high, the airflow can be circulated multiple times in the CO elimination chamber and the airflow circulation chamber when the second air volume control valve is opened and the second exhaust fan is started, and then the cyclic CO elimination operation can be performed by airflow circulation to effectively ensure the elimination effect of CO. When the elimination effect of CO still cannot be improved by airflow circulation, the fan is turned off, and the circulating airflow is heated by the heating component to form a high-temperature airflow, and then the high-temperature airflow is used to realize the activation and regeneration of each elimination component, which can realize the desorption effect of toxic substances on the flow channel surface and the elimination fan surface in the elimination component, and effectively improve the regeneration level of the elimination performance of each elimination component, so as to achieve the effect of repeated use of the elimination component.

[0039] The method has the advantages of simple implementation process, high intelligence, good safety performance, and the ability to continuously eliminate CO. It can efficiently eliminate the CO generated during the blasting process and can simultaneously remove some dust particles in the airflow, which is beneficial to reducing the degree of environmental pollution caused by blasting operations.
