Description

Technical Field

[0002] The water mist sprayed by fog cannons is extremely fine, reaching the micron level. During smog-prone weather, they can effectively reduce dust and decompose airborne particles, effectively breaking down pollutants and dust, and effectively alleviating smog. They quickly force airborne pollutants down to the ground, effectively cleaning and purifying the air. Multiple fog cannons are often deployed around waste incineration plants, creating a barrier to intercept odors generated by the plants and prevent them from impacting the living environment of surrounding residents.

[0003] The structure of the fog cannon barrel of the existing fog cannon trucks is that the high-pressure fan is in the middle of the fog cannon barrel, and then an atomizing device for generating fog for intercepting odor is arranged on the outer circumference of the high-pressure fan. The fog generated by the atomizing device is transported in the direction of the odor under the drive of the airflow generated by the high-pressure fan at the center position. However, the high-pressure airflow transporting the fog from the center position can easily cause the fog to disperse quickly during the transportation process, resulting in a shorter transportation distance.

[0027] Please also see Figures 1 to 3A preferred embodiment of the present invention provides a fog cannon vehicle odor interception system, comprising an information collection terminal, a data processing terminal, a data comparison terminal, a response database, and a first fog cannon vehicle 2 for intercepting odor. The first fog cannon vehicle 2 comprises a fog cannon mechanism 1 for intercepting odor and a high-pressure spray pump 3 for providing fog for intercepting odor to the fog cannon mechanism 1. The information collection terminal is arranged around the incineration plant. The information collection terminal is used to collect wind speed, wind direction, air pressure and odor concentration around the incineration plant and generate odor measurement information; the data processing terminal receives and processes the odor measurement information collected by the information collection terminal and then transmits it to the incineration plant. For the data comparison end, the response database is provided with a preset odor interception strategy for determining the odor interception method of the first fog cannon vehicle 2. The data comparison end calls the corresponding odor interception strategy from the response database according to the odor measurement information. The data comparison end calls the preset odor interception strategy adopted by the first fog cannon vehicle 2 for the data transmitted by the data processing end, and sends it to the first fog cannon vehicle 2. The first fog cannon vehicle 2 works according to the preset odor interception strategy; the fog cannon mechanism 1 makes the mist generated by the high-pressure spray pump 3 form a rotating airflow and transport it in the target direction. The rotating airflow has a motion component toward the center of rotation. The information collection end includes a wind speed sensor, a wind direction sensor, an air pressure sensor and a first odor concentration sensor. The preset odor interception strategies include a first strategy, a second strategy and a third strategy. The response database includes a first database provided with several first strategies, a second database provided with several second strategies and a third database provided with several third strategies. The first strategy is used to determine the interception path of the first fog cannon vehicle 2 for odor, the second strategy is used to determine the angle of the barrel 6 in the fog cannon mechanism 1, and the third strategy is used to determine the amount of fog sprayed by the fog cannon mechanism 1 and the interval time; the first fog cannon vehicle 2 intercepts odor according to the first strategy, the second strategy and the third strategy.In this solution, the wind speed sensor, wind direction sensor, air pressure sensor and first odor concentration sensor are all existing sensors that can realize corresponding functions. The data processing end is an existing mechanism that has the function of receiving sensor signals, processing the signals and then sending them to the database. The data comparison end is an existing structure that can call the preset odor interception strategy stored in the response database and can send the preset odor interception strategy to the first fog cannon vehicle 2. The response database is an existing structure that can store preset odor interception strategies. In this solution, the wind speed sensor, wind direction sensor, air pressure sensor and first odor concentration sensor can be set in several groups and arranged around the incineration plant to detect the wind speed, wind direction, air pressure and odor concentration near the incineration plant when the incineration plant emits odor. The above sensors send the collected signals to the data processing end, and the data processing end processes the collected signals and sends them to the data comparison end. The first database is preset with multiple first strategies related to the odor interception path, and the odor interception path involved in each first strategy is different. The second database is preset with multiple second strategies related to the angle of the fog cannon mechanism 1 toward the odor, that is, the target position, and each The angles of the fog cannon mechanism 1 directed toward the odor involved in the second strategy are all different; the third database is preset with a third strategy related to the spraying amount and spraying interval time of the fog cannon mechanism 1, and the mist spraying amount and spraying interval time of the fog cannon mechanism 1 involved in each third strategy are all different; wherein, the wind direction sensor processes the collected wind direction signal and transmits it together with the location information of the incineration plant to the data processing end, and the data processing end transmits the received wind direction and odor source location data to the data comparison end so that the data comparison end selects the first one with higher priority for the existing wind direction and odor source location information in the first database. The strategy is sent to the first fog cannon vehicle 2; the data comparison end receives the wind direction and wind speed data information processed by the data processing end, selects the second strategy with a higher priority in the second database, that is, the more appropriate strategy, and sends it to the first fog cannon vehicle 2; the data comparison end receives the odor concentration and wind speed data information processed by the data processing end, selects the more appropriate third strategy in the third database and sends it to the first fog cannon vehicle 2. The first fog cannon vehicle 2 can be provided with a receiving device for receiving the preset odor interception strategy. After receiving the first strategy, the second strategy and the third strategy, the first fog cannon vehicle 2 intercepts the odor according to the above strategies. In this solution, the fog cannon mechanism 1 can output fog that rotates toward the center of the entire fog in the direction of the odor. The rotating fog increases the integrity and compactness of the fog, which helps to increase the transportation distance and transportation accuracy of the fog, so that the first fog cannon vehicle 2 can use the method of this solution to accurately intercept the odor.

[0028] The fog cannon mechanism 1 includes a first air supply part 4 and a second air supply part 5. The first air supply part 4 and the second air supply part 5 both form airflows of specific gases, and the flow rate of the airflow output by the second air supply part 5 is greater than the flow rate of the airflow output by the first air supply part 4; the fog generated by the high-pressure spray pump 3 forms a fog airflow rotating toward the center of the fog due to the flow rate difference between the first air supply part 4 and the second air supply part 5 and is transported to the target position. In this solution, the specific airflow can be the air in the environment. The first air supply unit 4, the second air supply unit 5 and the high-pressure spray pump 3 are powered by an external energy supply device, which is some existing structure that can provide power for machinery, such as a generator. When it is necessary to intercept the odor generated by the incineration plant, the direction of the fog cannon mechanism 1 on the vehicle body is adjusted so that the first air supply unit 4 and the second air supply unit 5 are facing the direction of the odor, and the energy supply device is started to make the first air supply unit 4 and the second air supply unit 5 work, so that the air in the environment generates an airflow flowing in the direction of the odor. At the same time, the high-pressure spray pump 3 works to generate mist for intercepting the odor. Since there is a flow rate difference between the airflows generated by the first air supply unit 4 and the second air supply unit 5, the first air supply unit 4 and the second air supply unit 5 respectively blow different parts of the mist and blow the mist in the direction of the odor. Therefore, the mist is blown in the direction of the odor in the form of a rotating airflow. The rotating mist increases the compactness between the mists. Compared with non-rotating mist, it is less likely to be disturbed by the external environment during transportation and dispersed early, which greatly increases the transportation distance of the mist. At the same time, when the rotating mist reaches the location of the odor, the rotation of the mist can drive the gas in the surrounding environment to flow, so it is easier to roll the odor molecules in the air towards the mist, thereby optimizing the interception effect of the odor.

[0029] The fog cannon mechanism 1 includes a barrel 6, a support sleeve 7 is coaxially arranged in the inner cavity of the barrel 6, a first air supply part 4 is arranged on the outer side wall of the support sleeve 7, and a plurality of support rods 8 are also arranged on the outer side wall of the support sleeve 7. The support sleeve 7 is fixedly connected to the cavity wall of the inner cavity of the barrel 6 through the plurality of support rods 8. The second air supply part 5 is located on the outer side of the first air supply part 4 and is arranged along the circumference of the first air supply part 4. The mist generated by the high-pressure spray pump 3 is located directly in front of the first air supply part 4. At the same time, the second air supply part 5 is arranged circumferentially around the outer periphery of the first air supply part 4. The arrangement of the two air supply parts can increase the thrust on the mist, so that the mist can be transported farther. The second air supply part 5 generates an airflow at a faster speed than the airflow generated by the first air supply part 4 on the outer periphery of the first air supply part 4, thereby causing the mist to rotate toward the center of the entire mist.

[0030] The mist cannon mechanism 1 also includes an atomizing unit 9, which is fixedly connected to the inner cavity of the support sleeve 7. The atomizing unit 9 is used to evenly distribute the mist generated by the high-pressure spray pump 3 along the circumference directly in front of the barrel 6 based on the axis of the barrel 6. The atomizing unit 9 includes a diverter joint 10 and a plurality of atomizing nozzles 11 provided on the diverter joint 10. The diverter joint 10 is a disc-shaped joint, which is coaxially arranged with the barrel 6. The plurality of atomizing nozzles 11 are evenly distributed along the circumference of the diverter joint 10. After the mist generated by the high-pressure spray pump 3 enters the diverter joint 10, it is evenly sprayed out through each atomizing nozzle 11, flows through the front end of the first air supply unit, and flows toward the front end of the second air supply unit. The setting of the atomizing section 9 makes the mist distributed in front of the first air supply section 4 rotate inward as a whole toward the center of the entire mist, thereby forming an airflow similar to a circular rotation, making the mist more integrated and less likely to disperse during the transportation process. The evenly distributed setting of the atomizing nozzles 11 further optimizes the uniformity of the mist distribution.

[0031] The first air supply unit 4 includes a high-pressure fan 12, which includes an impeller 13 and a bearing 14. The bearing 14 is sleeved on the outer wall of the support sleeve 7, and the impeller 13 is rotatably connected to the support sleeve 7 through the bearing 14. In this solution, the driving method of the impeller 13 or the high-pressure fan 12 can adopt the driving method adopted by the existing first fog cannon vehicle 2 and is well known to those skilled in the art. The provision of the bearing 14 reduces the resistance of the impeller 13 during rotation, making the high-pressure fan 12 more stable during operation, while reducing the noise generated by the impeller 13 during rotation.

[0032] The second air supply unit 5 includes a nozzle ring 15, which is coaxially arranged with the barrel 6 and detachably connected to the barrel 6 wall at the front end of the first air supply unit 4. The nozzle ring 15 is provided with a plurality of spray holes 16, the length of which is arranged along the axis of the barrel 6 and distributed along the axis of the nozzle ring 15. The barrel 6 wall is also provided with a plurality of guide channels 17, each communicating with each of the spray holes 16. The second air supply unit 5 also includes a compressed gas delivery mechanism 18, which delivers high-pressure gas to each of the spray holes 16 through each of the guide channels 17, so that the second air supply unit 5 delivers fog to a wider area than the first air supply unit 4. The nozzle ring 15 and the barrel 6 can be threadedly connected, and the compressed gas delivery mechanism 18 can be a structure used in existing fog cannons to compress and deliver air or other gases. The compressed gas delivery mechanism 18 compresses the gas, which is then delivered through the guide channel 17 and ejected from the nozzle ring 15 through the plurality of nozzle holes 16, thereby rotating and delivering the mist. The removable connection between the nozzle ring 15 and the barrel 6 facilitates later cleaning of the nozzle holes 16 and guide channel 17.

[0033] The longitudinal direction of the atomizing nozzle 11 and the radial direction of the diverter joint 10 are arranged at an angle ranging from 30° to 60°. The front end of the atomizing nozzle 11 and the front end of the barrel 6 face the same side. The inner side wall of the nozzle ring 15 is provided with a concave guide groove 19 along the circumference of the nozzle ring 15. The guide groove 19 is used to guide the mist sprayed from the atomizing nozzle 11. The front end of the atomizing nozzle 11 adopts such an angle setting, and is combined with the setting of the guide groove 19 on the nozzle ring 15, so that the mist sprayed from the atomizing nozzle 11 flows into the guide groove 19, and under the action of the guide groove 19, it is easier to form a rotating mist airflow, thereby optimizing the structural design.

[0034] In this embodiment, the number of support rods 8 is 3-6, and the support rods 8 are evenly distributed along the circumference of the support sleeve 7 with the axis of the support sleeve 7 as the reference. Each support rod 8 is a cylindrical rod. This arrangement helps to reduce the resistance of the support rods 8 to the high-pressure airflow generated by the high-pressure blower 12, thereby reducing the impact on the flow direction and flow rate of the gas.

[0035] Example 2:

[0036] This embodiment can be further optimized based on Example 1. By setting up a second fog cannon vehicle and a second odor concentration sensor on the first fog cannon vehicle, the second odor concentration sensor is used to detect odor near the first fog cannon vehicle. The second fog cannon vehicle compensates for the odor that was not fully intercepted by the first fog cannon vehicle based on the data detected by the information collection terminal and the second odor concentration sensor. The odor interception strategy is configured with a priority. When the second fog cannon vehicle is performing compensatory interception, the priority of the preset odor interception strategy being executed by the first fog cannon vehicle changes. The data processing terminal assigns different priority values ​​to each third strategy in the third database after processing the data collected by the information collection terminal. When the odor concentration sensor detects that there is still odor around the first fog cannon vehicle, the priority value of the third strategy currently being used by the first fog cannon vehicle decreases. When the odor concentration sensor detects that there is no odor around the first fog cannon vehicle, the priority value of the third strategy currently being used by the first fog cannon vehicle increases. The difference in priority values ​​between different third strategies is an integer, and the value of each increase or decrease in the third strategy is 1. The data processing end assigns different values ​​to each third strategy in the third database based on the data collected by the information collection end. Due to various factors, such as excessive odor concentration or high wind speed, the first fog cannon vehicle cannot intercept 100% of the odor. The odor that is not intercepted will pass through the first fog cannon vehicle and flow to the residential area downwind. Therefore, a second fog cannon vehicle is set up to intercept the remaining odor that passes through the first fog cannon vehicle again. When the odor concentration sensor detects that there is no odor around the first fog cannon vehicle, the priority value of the third strategy used by the first fog cannon vehicle increases, and the second fog cannon vehicle does not operate at this time. When the odor concentration sensor detects that there is still odor around the first fog cannon vehicle, the priority value of the third strategy used by the first fog cannon vehicle decreases. At this time, the second fog cannon vehicle intercepts the remaining odor near the first fog cannon vehicle based on the data collected by the information collection end and the odor concentration sensor.The information collection terminal prioritizes each third strategy in the third database according to the collected information, such as odor concentration and wind speed, and assigns corresponding priority values ​​for the first fog cannon vehicle to select. The first fog cannon vehicle can select a third strategy with a higher priority to execute according to the size of the priority value; when executing a certain third strategy, if the concentration sensor can detect that there is still odor around the first fog cannon vehicle at this time, the priority value of the third strategy being executed by the first fog cannon vehicle will be reduced. If the concentration sensor detects that there is no odor around the first fog cannon vehicle at this time, the priority value of the third strategy being executed by the first fog cannon vehicle will be increased. When the vehicle is in the same wind speed and odor concentration again, the vehicle will be in the same wind speed and odor concentration again. Under the following conditions, the priority of each third strategy will change due to the change in the priority value of the third strategy adopted under the same circumstances in the previous time. That is, when encountering the same situation again, the third database will select a third strategy with a higher priority than the previous one and send it to the first fog cannon vehicle for execution. If the odor sensor on the first fog cannon vehicle still detects odor during this interception, the priority value of the newly adopted third strategy will be reduced by 1. If no odor is detected, the priority value will be increased by 1. This forms a model similar to deep learning, so that after facing the same wind speed and odor concentration many times, the third database will eventually be able to provide the most appropriate third strategy under these conditions to the first fog cannon vehicle. The fog cannon vehicle of the present invention can be used for emergency purposes when working in an incineration plant and can be used normally in a landfill.

[0037] Working principle:

[0038] In this solution, a rotating device for adjusting the direction of the barrel 6 can also be set on the existing first fog cannon vehicle 2; when it is necessary to intercept the odor generated by the incineration plant, the data comparison end receives the signal collected by the information collection end processed by the data processing end, and selects a preset odor interception strategy suitable for the wind speed, wind direction, air pressure and odor concentration conditions in the scene and sends it to the first fog cannon vehicle 2. The first fog cannon vehicle 2 adjusts the path of odor interception according to the received preset odor interception strategy, adjusts the interception angle of odor by adjusting the direction of the fog cannon mechanism 1 on the vehicle body so that the barrel 6 is facing the odor, adjusts the amount and interval time of fog output by the fog cannon mechanism 1 by adjusting the high-pressure spray pump 3, starts the energy supply equipment to make the impeller 13 in the high-pressure fan 12 rotate, thereby generating a high-pressure airflow inside the barrel 6 blowing in the direction of the odor, and at the same time, the compressed gas delivery mechanism 18 works to generate high-pressure gas, and the high-pressure gas passes through the guide channel 17 from the spray The air is sprayed out from the hole 16 to generate an air flow faster than the flow rate generated by the high-pressure fan 12 in the direction of the odor. At the same time, the high-pressure spray pump 3 works to generate mist for intercepting the odor. In this scheme, the high-pressure spray pump 3 can transport the generated high-pressure mist to the diversion joint 10 through a pipeline. Under the action of the diversion joint 10, the high-pressure mist is divided into several streams and is evenly distributed along the circumference of the diversion joint 10 through the atomizing nozzle 11 in front of the impeller 13. Since there is a flow rate difference between the air flows generated by the first air supply part 4 and the second air supply part 5, the first air supply part 4 generates a thrust on the position near the middle of the mist, and the second air supply part 5 generates a thrust on the outer side of the mist compared to the first air supply part 4, so that the mist as a whole rotates inward toward the middle of the entire mist to form a rotating airflow. The rotating airflow has a motion component toward the center of rotation. The rotating airflow has strong stability and is not easy to disperse prematurely, so that the precise interception of the mist in this scheme can be achieved.

[0039] When the odor concentration sensor detects that there is no odor around the first fog cannon vehicle, the priority value of the third strategy currently being used by the first fog cannon vehicle increases, and the second fog cannon vehicle does not operate at this time. When the odor concentration sensor detects that there is still odor around the first fog cannon vehicle, the priority value of the third strategy currently being used by the first fog cannon vehicle decreases, and the second fog cannon vehicle intercepts the remaining odor near the first fog cannon vehicle by combining the data collected by the information acquisition terminal and the odor concentration sensor. The information acquisition terminal prioritizes each third strategy in the third database based on the collected information, such as odor concentration and wind speed, and assigns corresponding priority values ​​for the first fog cannon vehicle to select. The first fog cannon vehicle can select a third strategy with a higher priority based on the size of the priority value. When executing a third strategy, if the concentration sensor can detect that there is still odor around the first fog cannon vehicle, the priority value of the third strategy currently being implemented by the first fog cannon vehicle decreases. If the concentration sensor detects that there is no odor around the first fog cannon vehicle, the priority value of the third strategy currently being implemented by the first fog cannon vehicle increases. When the situation is again with the same wind speed and odor concentration, the priority value of the third strategy currently being implemented by the first fog cannon vehicle increases. Under the conditions of , the priority of each third strategy will change due to the change in the priority value of the third strategy adopted under the same circumstances in the previous time. That is, when encountering the same situation again, the third database will select a third strategy with a higher priority than the previous one and send it to the first fog cannon vehicle for execution. If the odor sensor on the first fog cannon vehicle still detects odor during this interception, the priority value of the newly adopted third strategy will be reduced by 1. If no odor is detected, the priority value will be increased by 1. In this way, a model similar to deep learning is formed, so that after facing the same wind speed and odor concentration many times, the third database can finally provide the most suitable third strategy under these conditions to the first fog cannon vehicle.
