Description

Technical Field

[0001] This invention relates to the technical field of manufacturing special equipment for solid waste pollution environmental protection, specifically to a dynamic intelligent adjustment device for recycling and extinguishing environmental pollutants and its application in airport terminals. Background Technology

[0002] The terminal building (primarily referring to the passenger terminal, i.e., the waiting area) is the main building in the terminal area. The design of the terminal building must consider not only its function but also its environment, artistic atmosphere, and national (or local) style. One side of the terminal building connects to the apron, while the other side connects to the ground transportation system. Passengers, baggage, and cargo complete various procedures and undergo necessary checks within the terminal building to facilitate the transfer of modes of transport.

[0003] Meanwhile, airport terminals are also large-scale urban buildings characterized by complex structures, large internal spaces, and high passenger flow. In the event of a fire, they are highly susceptible to causing mass casualties and significant economic losses. Therefore, to ensure the safety of the terminal and its passengers, it is crucial to study the development patterns of fires within the terminal and to implement effective fire prevention measures. This necessitates conducting fire suppression tests on the imported fire-fighting equipment to assess its effectiveness within the terminal.

[0004] Currently, the fire-fighting equipment introduced by our company, Chongqing Jiangbei International Airport Co., Ltd., is the large-space fire monitor. The large-space fire monitor is a highly intelligent, all-round active water spray fire extinguishing system. Therefore, when testing the fire extinguishing effect of the large-space fire monitor inside the terminal building, diesel oil, cotton yarn, etc. are usually used as test combustibles. During the test, the combustion of combustibles will produce a large amount of toxic and harmful air pollutants and solid pollutants. The large-space fire monitor can only extinguish the fire and cannot recover the air pollutants and solid pollutants produced by the combustion of combustibles. As a result, the air pollutants and solid pollutants are scattered everywhere, which not only affects the surrounding environment of the terminal building, but also affects the travel experience of passengers in the terminal building. Moreover, the strong smell of air pollutants may cause terminal building cleaners to mistakenly believe that there is a fire, which may easily lead to false alarms to the airport fire brigade.

[0005] To address this, the inventors designed a device that, when testing the fire extinguishing effect of a large-space fire cannon, can recover solid pollutants generated by the combustion of combustibles during fire suppression, while also recovering some gaseous pollutants. This significantly reduces the impact of gaseous and solid pollutants on the surrounding environment of the terminal building and minimizes the impact on the travel experience of passengers. Summary of the Invention

[0006] The present invention aims to provide a dynamic intelligent debugging device for recovering environmental pollutants during fire extinguishing and its application in airport terminals. When testing the fire extinguishing effect of fire cannons in large spaces, it can recover solid pollutants generated by the combustion of combustibles during fire extinguishing, and at the same time recover some gaseous pollutants, which greatly reduces the impact of gaseous and solid pollutants on the surrounding environment of the terminal and reduces the impact on the travel experience of passengers in the terminal.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: 1) A dynamic intelligent adjustment device for recovering environmental pollutants during fire extinguishing, comprising a recovery basin, an adjustment basin, and a combustion basin arranged sequentially from the outside to the inside, wherein the middle part of the recovery basin is recessed inward for the adjustment basin to be supported and installed, and the middle part of the adjustment basin is recessed inward for the recovery basin to be supported and installed. The recovery basin is configured with a pollutant recovery structure for recovering pollutants in the fire extinguishing environment. The pollutant recovery structure includes a separation component for separating air pollutants and solid-liquid mixed pollutants in the fire extinguishing environment. The burning basin is configured to have a holding trough for holding combustibles, and the holding trough has a sensor for sensing the combustion temperature of the combustibles, and the sensor is used to determine the size of the fire of the combustibles in the burning basin. The test basin is configured with a gas supply and combustion-supporting structure that is linked to the switching of the separation component. The gas supply and combustion-supporting structure draws in air pollutants from the separation component and adsorbs and sieves them to obtain combustion-supporting gas. The combustion-supporting gas is transported toward the combustion basin by the sensing information of the sensor, which can control the size of the fire of the combustible material.

[0008] The above technical solution was used to test the fire extinguishing effect of the large-space fire monitor. Diesel fuel and cotton yarn were used as the test combustibles. The combustibles were placed in the holding tank of the combustion basin. The combustibles in the holding tank were ignited, causing them to burn. During the combustion process, a test tank fitted on the outer surface of the combustion basin sensed the combustion temperature of the combustibles through a sensor inside the combustion basin. The sensor transmitted the sensed combustion temperature information to the gas supply and combustion aid structure set in the test tank. The gas supply and combustion aid structure controlled the delivery of its own combustion aid gas to the holding tank of the combustion basin based on the combustion temperature information. Under the action of the combustion aid gas, the fire intensity of the combustibles increased. When the fire intensity of the combustibles increased to the test fire extinguishing requirements, the large-space fire monitor was activated to spray water to extinguish the fire.

[0009] When the large-space fire cannon is spraying water for fire extinguishing, the recovery basin installed on the outer surface of the test basin activates the pollutant recovery structure. The pollutant recovery structure recovers the environmental pollutants generated during the combustion of combustibles. During the recovery process, the environmental pollutants are mixed with the water flow. After passing through the separation components within the pollutant recovery structure, the mixed environmental pollutants are separated into air pollutants and solid-liquid mixed pollutants. The solid-liquid mixed pollutants are collected within the pollutant recovery structure, thereby reducing the impact of solid-liquid mixed pollutants on the surrounding environment during the fire extinguishing test of the large-space fire cannon. At the same time, it reduces the labor intensity of terminal cleaning staff in cleaning the terminal area when the large-space fire cannon is being tested for fire extinguishing.

[0010] Air pollutants are transported from the pollutant recovery structure to the gas supply and combustion-supporting structure. The structure draws in the pollutants and performs adsorption and sieving to obtain combustion-supporting gas. This gas is stored in the gas supply and combustion-supporting structure within the testing basin. Based on the combustion temperature information sensed by the sensors, the structure directs the gas supply and combustion-supporting structure towards the holding tank. This allows for the control of the fire intensity of combustibles in the holding tank via the combustion-supporting gas, while also recovering environmental pollutants generated during fire suppression using large-space fire monitors. The adsorption and sieving of air pollutants to obtain combustion-supporting gas achieves resource reuse, significantly reducing material and labor costs. When testing the fire suppression effect of large-space fire monitors, this technical solution can recover solid pollutants generated during the fire suppression process, as well as some gaseous pollutants, greatly reducing the impact of gaseous and solid pollutants on the surrounding environment of the terminal and minimizing the impact on the passenger travel experience.

[0011] 2) According to the dynamic intelligent adjustment device for recovering environmental pollutants during fire extinguishing as described in 1), wherein: The pollutant recovery structure includes a storage box located at the bottom of the recovery basin. The storage box has a plurality of suction holes evenly distributed along its circumference. All suction holes are connected to an absorption channel that is arranged around the upper surface of the recovery basin. The storage box is equipped with four secondary exhaust fans that are spaced apart and face the absorption channel. Each secondary exhaust fan is coaxially connected to a corresponding secondary servo motor. The secondary servo motor is mounted on the side wall of the corresponding suction hole, and a protective sleeve is fitted on the end of the secondary servo motor away from the secondary exhaust fan.

[0012] This technical solution uses a secondary exhaust fan as the driving point to divide the storage box and absorption channel into two areas. The secondary exhaust fan is driven by a corresponding secondary servo motor. The secondary exhaust fan generates negative pressure, which is then drawn through the absorption channel to suck up the fire extinguishing environmental pollutants floating around the combustion basin and into the storage box. This can recover the fire extinguishing environmental pollutants formed when combustibles in the combustion basin are burning. Therefore, when conducting fire extinguishing tests on large-space fire cannons, the impact of the fire extinguishing test on the terminal building environment is reduced.

[0013] Meanwhile, in this technical solution, all secondary exhaust fans are arranged in four phases, so that each secondary exhaust fan faces a different direction of the absorption channel. When the secondary servo motor is started, the secondary servo motor drives the secondary exhaust fan to suck up the corresponding direction of the absorption channel and suck the fire extinguishing environmental pollutants in that direction into the storage box. In order to ensure the operation of the secondary servo motor, a protective sleeve is installed on the end of the secondary servo motor away from the secondary exhaust fan. The protective sleeve is located inside the storage box and reduces the impact of fire extinguishing environmental pollutants in the storage box on the secondary servo motor.

[0014] In this technical solution, a drain port is provided at the bottom of the storage box, and a removable cover is installed inside the drain port. Therefore, after the storage box has finished storing fire extinguishing environmental pollutants, the fire extinguishing environmental pollutants in the storage box can be discharged by removing the cover and opening the drain port, so that the technical solution can be reused later.

[0015] 3) A dynamic intelligent adjustment device for recovering environmental pollutants during fire extinguishing, as described in 2), wherein: The top of the storage box is equipped with an extraction box that communicates with the storage box. The top of the extraction box is equipped with a main servo motor. The main servo motor is coaxially connected to a main extraction fan located inside the extraction box. The separation component is installed between the extraction box and the storage box. The extraction box is connected to the gas supply and combustion aid structure.

[0016] In this technical solution, the fire extinguishing environmental pollutants stored in the storage box include air pollutants and solid-liquid mixed pollutants. The solid-liquid mixed pollutants are stored in the storage box, while the air pollutants are driven by the main exhaust fan. The main servo motor drives the main exhaust fan to rotate, which generates negative pressure, thereby introducing the air pollutants in the storage box into the extraction box. During the process of introducing the air pollutants from the storage box to the extraction box, the separation component located between the storage box and the extraction box adsorbs and sieves the air pollutants to obtain combustion-supporting gas.

[0017] Meanwhile, since the main exhaust fan is located inside the exhaust box, it draws air pollutants from the storage tank into the exhaust box. The combustion-supporting gas in the exhaust box is then transported to the gas supply and combustion-supporting structure by the main exhaust fan. This allows the gas supply and combustion-supporting structure to support the combustion of combustibles in the combustion basin, increasing the intensity of the fire. This enables fire extinguishing tests on large-space fire monitors. During this process, the technical solution can recycle and reuse the recovered fire extinguishing environmental pollutants, thereby reducing cost increases.

[0018] 4) A dynamic intelligent adjustment device for recovering environmental pollutants during fire extinguishing, as described in 3), wherein: The separation component includes a first filter layer, a second filter layer, and a third filter layer arranged sequentially along the height direction. The first filter layer and the second filter layer are separated by a first filter screen that is wavy, and the second filter layer and the third filter layer are separated by a second filter screen that is arranged laterally. The first filter layer is filled with a neutral desiccant, the second filter layer is filled with activated carbon, and the third filter layer is filled with fine filter cotton.

[0019] In the above technical solution, the separation component uses a second filter screen to separate the second and third filter layers, and combines this with the fine filter cotton filled in the third filter layer to effectively filter solid particles and water vapor in the air pollutants drawn in during the main exhaust fan's suction process. The filtered air pollutants enter the second filter layer through the second filter screen. The activated carbon filled in the second filter layer absorbs harmful gases and water vapor such as organic hydrocarbons, SO2, NO2, and O3 in the air pollutants.

[0020] The first filter screen, which is wavy, separates the first filter layer and the second filter screen. In this technical solution, the first filter screen is designed to be wavy, which increases the contact area between the first filter screen and the first filter layer, as well as the contact area between the first filter screen and the second filter layer. The first filter screen can block fine particles in the air pollutants. Therefore, the air pollutants pass through the second filter layer and then through the first filter screen into the first filter layer. The neutral desiccant filled in the first filter layer filters and adheres the gas that has been absorbed by the activated carbon to obtain a combustion-supporting gas containing oxygen.

[0021] Meanwhile, in this technical solution, air pollutants pass through fine filter cotton, activated carbon, and neutral desiccant in sequence, so that most of the harmful gases inside the air pollutants can be removed to obtain oxygen-containing combustion-supporting gas. The oxygen-containing combustion-supporting gas can be reused to control the increase in the combustion flame of combustibles in the combustion basin, thereby realizing the fire extinguishing test of the large-space fire cannon with increased combustion flame.

[0022] 5) A dynamic intelligent adjustment device for recovering environmental pollutants during fire extinguishing, as described in 3), wherein: The test basin is provided with a receiving space for accommodating the gas supply and combustion assist structure. The gas supply and combustion assist structure includes a gas supply box disposed in the receiving space. The gas supply box is arranged around the perimeter of the test basin. The bottom of the gas supply box has four main gas pipes that surround the perimeter of the extraction box. The two ends of each main gas pipe are connected to the sides of the gas supply box and the extraction box, respectively. The top of the gas supply box has several branch gas pipes that surround the perimeter of the recovery basin. The two ends of each branch gas pipe are connected to the gas supply box and the holding tank, respectively. A control valve is installed in each branch gas pipe.

[0023] The above technical solution employs a receiving chamber within the test basin to accommodate the gas-supplying combustion-supporting structure, ensuring a certain distance between the structure and the holding tank. This reduces the impact of heat generated during combustion of combustibles in the holding tank on the gas-supplying combustion-supporting structure. Simultaneously, during the main exhaust fan's suction process, the combustion-supporting gas in the exhaust box is drawn and transported towards the gas supply box via the main gas pipeline, allowing the gas supply box to store the combustion-supporting gas. When combustion-supporting gas is needed, the control valve of the branch gas pipe is opened, transporting the combustion-supporting gas from the gas supply box towards the holding tank, thus aiding combustion of the combustibles in the holding tank.

[0024] Furthermore, since there are four main gas pipelines between the gas supply box and the gas extraction box in this technical solution, and these four main gas pipelines are arranged around the gas extraction box in different directions towards the gas supply box, the combustion-supporting gas in the gas extraction box is transported to the gas supply box through the main gas pipelines in different directions under the suction of the main exhaust fan. When the combustibles in the holding tank need to be assisted in combustion, the control valve is opened, so that the combustion-supporting gas in the gas supply box is transported to the holding tank through the branch gas pipelines around the recovery basin. The evenly distributed branch gas pipelines uniformly assist the combustion of the combustibles in the holding tank, which can achieve complete combustion of the combustibles and increase the fire intensity, thereby enabling the fire extinguishing test of the large-space fire monitor.

[0025] 6) A dynamic intelligent adjustment device for recovering environmental pollutants during fire extinguishing, as described in 5), wherein: An arched combustion-supporting bridge plate with an arched longitudinal section is provided between the top of the test basin and the top of the firing basin. The combustion-supporting bridge plate has a circular structure and surrounds between the test basin and the firing basin. The bottom of the outer ring of the combustion-supporting bridge plate is fixed to the top of the test basin, and the bottom of the inner ring of the combustion-supporting bridge plate is fixed to the top of the firing basin. Several air supply holes are opened on the combustion-supporting bridge plate along its circumferential direction. All air supply holes are connected to the corresponding branch gas pipes. All air supply holes surround the periphery of the firing basin and face the holding trough.

[0026] In the above technical solution, the combustion-supporting arch bridge plate connects the test basin and the combustion basin, so that the test basin can form a space to accommodate the gas supply and combustion-supporting structure on the one hand, and serve as a direction to guide the delivery of combustion-supporting gas on the other hand. The gas supply holes evenly distributed on the combustion-supporting arch bridge plate along its circumference deliver the combustion-supporting gas in the branch gas pipe to the corresponding gas supply holes. The combustion-supporting gas is then injected into the holding tank of the combustion basin through the gas supply holes. Since the gas supply holes are evenly distributed on the combustion-supporting arch bridge plate, the combustion-supporting gas can be evenly injected into the combustibles in the holding tank, so that the combustibles can burn evenly and completely, increasing the fire intensity.

[0027] 7) A dynamic intelligent adjustment device for recovering environmental pollutants during fire extinguishing, as described in 1), wherein: The sensing element includes a raised ball embedded in the bottom of the holding tank. The upper part of the raised ball protrudes from the bottom of the holding tank, and the lower part of the raised ball passes through the holding tank and is located in the adjustment basin. A heat insulation layer is provided on the outer surface of the lower part of the raised ball. The heat insulation layer is made of polyurethane foam. Several temperature sensors are evenly distributed on the outer surface of the heat insulation layer. The element also includes a microprocessor, which is electrically connected to the temperature sensors, the gas supply and combustion structure, and the pollutant recovery structure, respectively.

[0028] In the above-mentioned technical solution, the upper part of the raised ball protrudes from the bottom of the holding tank, so that the combustion heat of the combustibles in the holding tank is transferred to the position of the heat insulation layer through the lower part of the raised ball. Since the heat insulation layer is made of polyurethane foam, the characteristics of polyurethane foam, such as closed-cell microporous foam and low thermal conductivity, are used to greatly reduce the combustion heat transferred by the raised ball, thereby reducing the impact of combustion heat on the operation of the main servo motor located below the raised ball. At the same time, the temperature sensor set on the outer surface of the heat insulation layer can detect the reduced combustion temperature information of the raised ball and transmit the combustion temperature information to the microprocessor, so that the microprocessor can obtain the combustion temperature value of the combustibles in the holding tank.

[0029] Meanwhile, a preset value is set within the microprocessor. When the combustion temperature exceeds the preset value, it meets the fire extinguishing test requirements for the large-space fire cannon. Simultaneously, the microprocessor issues a command to activate the pollutant recovery structure, enabling the large-space fire cannon to recover pollutants from the surrounding fire extinguishing environment during the fire extinguishing process. In practice, the microprocessor issues commands to sequentially activate the secondary servo motor and the main servo motor of the pollutant recovery structure. Activating the secondary servo motor enables the recovery of pollutants from the surrounding fire extinguishing environment, while activating the main servo motor enables the separation of air pollutants and solid-liquid mixed pollutants within the fire extinguishing environment.

[0030] Conversely, when the combustion temperature is lower than the preset value, the microprocessor issues a command to activate the gas supply and combustion-supporting structure to supply combustion-supporting gas to the combustibles in the holding tank, so that the combustion temperature of the combustibles in the holding tank reaches the preset value in the microprocessor. This allows for fire extinguishing tests on the large-space fire monitor. In practice, the microprocessor activates the control valve in the gas supply and combustion-supporting structure. When the main servo motor starts, it can adsorb and sieve air pollutants to obtain combustion-supporting gas and store it in the gas supply box. By opening and closing the control valve, the combustibles in the holding tank are periodically supplied with combustion-supporting gas.

[0031] 8) A dynamic intelligent adjustment device for recovering environmental pollutants during fire extinguishing, as described in 7), wherein: The insulation layer has a liquid storage tank on each side of the top surface of the vacuum box. The bottom of the storage tank has an inlet hole extending toward the liquid storage tank. The side of the liquid storage tank has a drain hole, which is connected to an input hole on the side of the storage tank through a pipe.

[0032] During the fire extinguishing process of a large-space fire cannon spraying water, the water will be sprayed into the holding tank. Therefore, the liquid inlet hole at the bottom of the holding tank can introduce the water into the storage tank below the holding tank, realizing the recovery of the water in the holding tank. In addition, since there are two storage tanks located on both sides of the heat insulation layer, the water will absorb the heat of the space during the heat conduction process of the heat insulation layer, reducing the heat generated by the combustion of combustibles from affecting the operation of the main servo motor, and also cooling the heat generated by the operation of the main servo motor. Furthermore, the drain hole on the side of the storage tank and the input hole on the side of the storage tank are connected by a pipe, thereby introducing the recovered water in the storage tank into the storage tank, and then discharging the recovered water through the drain outlet.

[0033] 9) A dynamic intelligent adjustment device for recovering environmental pollutants during fire extinguishing, as described in 6), wherein: The lower surface of the firing basin is covered with a heat insulation layer. The periphery of the heat insulation layer extends toward the combustion-supporting arch bridge plate and is arranged on the lower surface of the combustion-supporting arch bridge plate. Corresponding through holes are opened on the heat insulation layer for the liquid inlet hole of the holding tank and the air supply hole of the combustion-supporting arch bridge plate. The heat insulation layer is made of rubber and plastic heat insulation material.

[0034] The insulation layer in the above-mentioned technical solution can keep the combustibles in the holding tank of the combustion basin warm, maintaining the combustion temperature of the combustibles in the holding tank for a period of time. This can more effectively achieve the effect of testing fire cannons in large spaces. At the same time, the insulation layer in this technical solution is made of rubber and plastic insulation material, which gives the insulation layer good elasticity and shock resistance. The insulation layer can effectively mitigate the impact of water sprayed into the holding tank by the fire cannon in a large space. In addition, the through holes opened on the insulation layer correspond to the liquid inlet hole of the holding tank and the air supply hole of the combustion-supporting arch bridge plate, so that the liquid inlet hole is connected to the liquid storage tank and the air supply hole is connected to the holding tank.

[0035] 10) An application of a dynamic intelligent adjustment device for recovering environmental pollutants from fire extinguishing in an airport terminal, wherein the above-described dynamic intelligent adjustment device for recovering environmental pollutants from fire extinguishing is applied to the airport terminal, and the method of use includes: Step 1: The tester places combustible material in the holding tank of the firing basin and ignites the combustible material in the holding tank, causing the combustible material to burn in the holding tank; Step 2: After the tester completes the ignition operation in Step 1, the sensor in the holding tank senses the combustion temperature information of the combustibles and obtains the combustion temperature value. Simultaneously, the pollutant recovery structure of the recovery basin is activated, so that the pollutant recovery structure can recover pollutants from the surrounding environment. Step 3: In step 2, when the combustion temperature value is equal to or greater than the preset value in the microprocessor, the tester will activate the large-space fire cannon to extinguish the combustibles in the combustion basin. At the same time, the pollutant recovery structure will continuously recover the fire-fighting environmental pollutants in the surrounding environment and separate the air pollutants and solid-liquid mixed pollutants in the fire-fighting environmental pollutants through the separation component. Step 4: In step 2, when the combustion temperature is less than the preset value in the microprocessor, the microprocessor sends an instruction to start the gas supply and combustion-supporting structure of the test basin. The gas supply and combustion-supporting structure draws in air pollutants and adsorbs and sieves them to obtain combustion-supporting gas, and controls the combustion-supporting gas to be transported toward the combustion basin so that the combustion temperature of the combustible is equal to or greater than the preset value in the microprocessor. Then, the steps in step 3 are repeated.

[0036] Compared with the prior art, the present invention also has the following technical effects: When testing the fire extinguishing effect of a large-space fire cannon, this invention can recover solid pollutants generated by the combustion of combustibles during fire extinguishing, and at the same time recover some gaseous pollutants, greatly reducing the impact of gaseous and solid pollutants on the environment around the terminal building and minimizing the impact on the travel experience of passengers in the terminal building.

[0038] The following detailed description illustrates the specific implementation method: The reference numerals in the accompanying drawings include: 1. Recovery basin; 2. Debugging basin; 3. Combustion-supporting arch bridge plate; 4. Burning basin; 5. Containing space; 6. Gas supply box; 7. Main servo motor; 8. Gas supply hole; 9. Raised ball; 10. Absorption channel; 11.

Temperature sensor.

[0039] See the example. Figure 1 and Figure 2 As shown in the figure, the dynamic intelligent adjustment device for recovering environmental pollutants during fire extinguishing in this embodiment includes a recovery basin 1, an adjustment basin 2 and a fire-bearing basin 4 arranged sequentially from the outside to the inside. The middle part of the recovery basin 1 is recessed inward to support the installation of the adjustment basin 2, and the middle part of the adjustment basin 2 is recessed inward to support the installation of the recovery basin 1.

[0040] In this embodiment, the recovery basin 1 is configured to have a pollutant recovery structure for recovering pollutants in the fire extinguishing environment. The pollutant recovery structure has a separation component for separating air pollutants and solid-liquid mixed pollutants in the fire extinguishing environment. The burning basin 4 is configured to have a holding tank for holding combustibles. The holding tank has a sensor for sensing the combustion temperature of the combustibles, and the sensor is used to determine the size of the fire of the combustibles in the burning basin 4.

[0041] The test basin 2 is configured with a gas supply and combustion-supporting structure that is linked to the switching of the separation component. The gas supply and combustion-supporting structure draws in air pollutants in the separation component and adsorbs and sieves them to obtain combustion-supporting gas. The combustion-supporting gas is transported toward the combustion basin 4 by the sensing information of the sensor, which can control the size of the fire of the combustible material.

[0042] To test the fire extinguishing effect of the large-space fire monitor, diesel fuel and cotton yarn were used as the test combustibles. The combustibles were placed in the holding tank of the combustion basin 4. The combustibles in the holding tank were ignited, causing them to burn. During the combustion process, the test tank 2, which is fitted on the outer surface of the combustion basin 4, sensed the combustion temperature of the combustibles through the sensing element inside the combustion basin 4. The sensing element transmitted the sensed combustion temperature information to the gas supply and combustion aid structure set in the test tank 2. The gas supply and combustion aid structure controlled the delivery of its own combustion aid gas to the holding tank of the combustion basin 4 according to the combustion temperature information. Under the action of the combustion aid gas, the fire intensity of the combustibles increased. When the fire intensity of the combustibles increased to the test fire extinguishing requirements, the large-space fire monitor was activated to spray water to extinguish the fire.

[0043] When the large-space fire cannon is spraying water for fire extinguishing, the recovery basin 1, which is fitted on the outer surface of the test basin 2, activates the pollutant recovery structure. The pollutant recovery structure recovers the fire extinguishing environmental pollutants generated during the combustion of combustibles. During the recovery process, the fire extinguishing environmental pollutants are mixed with the water flow. After passing through the separation component in the pollutant recovery structure, the mixed fire extinguishing environmental pollutants are separated into air pollutants and solid-liquid mixed pollutants. The solid-liquid mixed pollutants are collected in the pollutant recovery structure, thereby reducing the impact of solid-liquid mixed pollutants on the surrounding environment when the large-space fire cannon is tested for fire extinguishing. At the same time, it reduces the labor intensity of the terminal cleaning staff in cleaning the terminal area when the large-space fire cannon is tested for fire extinguishing.

[0044] Air pollutants are transported from the pollutant recovery structure to the gas supply and combustion-supporting structure. The gas supply and combustion-supporting structure draws in the air pollutants and performs adsorption and sieving to obtain combustion-supporting gas within the air pollutants. The obtained combustion-supporting gas is stored in the gas supply and combustion-supporting structure of the test basin 2. Based on the combustion temperature information sensed by the sensor, the gas supply and combustion-supporting structure is controlled to deliver combustion-supporting gas into the holding tank. In this way, the size of the fire in the holding tank can be controlled by the combustion-supporting gas, and the environmental pollutants generated during the fire extinguishing process of the large-space fire cannon can be recovered. The air pollutants are adsorbed and sieved to obtain combustion-supporting gas, thereby realizing resource reuse and greatly reducing material and labor costs. In this embodiment, when testing the fire extinguishing effect of the large-space fire cannon, it can recover the solid pollutants generated by the combustion of combustibles and some gaseous pollutants, which can greatly reduce the impact of gaseous and solid pollutants on the surrounding environment of the terminal building and reduce the impact on the travel experience of passengers in the terminal building.

[0045] See Figure 2As shown, the more specific structure of the pollutant recovery structure in this embodiment is as follows: The pollutant recovery structure includes a storage box 21 set at the bottom of the recovery basin 1. The storage box 21 has a plurality of suction holes evenly opened along its circumferential direction. All suction holes are connected to the absorption channel 10 that is opened around the upper surface of the recovery basin 1. The storage box 21 is equipped with four secondary exhaust fans 23 that are spaced apart and face the absorption channel 10 along its circumferential direction. Each secondary exhaust fan 23 is coaxially connected to a corresponding secondary servo motor 22. The secondary servo motor 22 is installed on the side wall of the corresponding suction hole. The end of the secondary servo motor 22 away from the secondary exhaust fan 23 is covered with a protective sleeve.

[0046] The storage box 21 and the absorption channel 10 are divided into two areas by the secondary exhaust fan 23 as the driving point. The secondary exhaust fan 23 is driven by the corresponding secondary servo motor 22. The secondary exhaust fan 23 draws in negative pressure and draws in the fire-fighting environmental pollutants floating around the fire-fighting basin 4 through the absorption channel 10 and into the storage box 21. In this way, the fire-fighting environmental pollutants formed by the combustibles in the fire-fighting basin 4 during combustion can be recovered. Therefore, the fire-fighting test of the large-space fire cannon can be carried out, reducing the impact of the fire-fighting test on the terminal building environment.

[0047] Meanwhile, several air holes are opened on the outer wall of the recycling basin 1 along its circumferential direction. All the air holes are connected to the absorption channel 10. A screen plate 11 is installed in each air hole. In this embodiment, the several air holes are designed to be arranged around the outer wall of the recycling basin 1, so that the air holes are closer to the ground. In this way, when the secondary exhaust fan 23 runs and draws in the outside air, other substances are isolated by the screen plate 11, so that the outside air can be drawn into the storage box 21 through the air holes. This realizes that when the pollution recycling structure is started for the first time, the outside air is introduced into the storage box 21 and the gas supply and combustion structure is supplied with combustion gas.

[0048] Meanwhile, in this embodiment, four secondary exhaust fans 23 are arranged at intervals to ensure that each secondary exhaust fan 23 faces a different direction of the absorption channel 10. When the secondary servo motor 22 is started, the secondary servo motor 22 drives the secondary exhaust fan 23 to suck up the corresponding direction of the absorption channel 10 and suck the fire extinguishing environmental pollutants in that direction into the storage box 21. In order to ensure the operation of the secondary servo motor 22, in this embodiment, a protective sleeve is put on the end of the secondary servo motor 22 away from the secondary exhaust fan 23. The protective sleeve is located in the storage box 21 and reduces the impact of the fire extinguishing environmental pollutants in the storage box 21 on the secondary servo motor 22.

[0049] In addition, in this embodiment, a drain port is provided at the bottom of the storage box 21, and a detachable cover is installed inside the drain port. Therefore, after the storage box 21 has finished storing fire extinguishing environmental pollutants, the fire extinguishing environmental pollutants in the storage box 21 can be discharged by removing the cover and opening the drain port, so that the storage box 21 can be reused in the future.

[0050] Meanwhile, an extraction box 16 connected to the storage box 21 is provided on the top of the storage box 21. A main servo motor 7 is provided on the top of the extraction box 16. The main servo motor 7 is coaxially connected to a main extraction fan 17 located inside the extraction box 16. A separation component is installed between the extraction box 16 and the storage box 21. The extraction box 16 is connected to the gas supply and combustion structure.

[0051] In this embodiment, the fire extinguishing environmental pollutants stored in the storage box 21 include air pollutants and solid-liquid mixed pollutants. The solid-liquid mixed pollutants are stored in the storage box 21, while the air pollutants are driven by the main exhaust fan 17. The main servo motor 7 drives the main exhaust fan 17 to rotate, which generates negative pressure in the main exhaust fan 17, thereby introducing the air pollutants in the storage box 21 into the extraction box 16. During the process of introducing the air pollutants from the storage box 21 to the extraction box 16, the separation component located between the storage box 21 and the extraction box 16 adsorbs and sieves the air pollutants to obtain combustion-supporting gas.

[0052] Meanwhile, since the main exhaust fan 17 is located inside the exhaust box 16, the main exhaust fan 17 draws air pollutants from the storage box into the exhaust box 16. The combustion-supporting gas in the exhaust box 16 is transported to the gas supply and combustion-supporting structure by the main exhaust fan 17, so that the gas supply and combustion-supporting structure can assist the combustion of combustibles in the combustion basin 4, which can increase the fire intensity of the combustibles, thereby conducting fire extinguishing tests on the large-space fire cannon. In this process, this embodiment can recycle and reuse the recovered fire extinguishing environmental pollutants, thereby reducing the increase in costs.

[0053] For the structure of the separate components, see [link / reference]. Figure 2 As shown, the separation component includes a first filter layer 18, a second filter layer 19, and a third filter layer 20 arranged sequentially along the height direction. The first filter layer 18 and the second filter layer 19 are separated by a wavy first filter screen, and the second filter layer 19 and the third filter layer 20 are separated by a transversely arranged second filter screen. The first filter layer 18 is filled with a neutral desiccant, the second filter layer 19 is filled with activated carbon, and the third filter layer 20 is filled with fine filter cotton.

[0054] In the above embodiment, the separation component uses a second filter screen to separate the second filter layer 19 and the third filter layer 20. Combined with the fine filter cotton filled in the third filter layer 20, it can effectively filter solid particles and water vapor in the air pollutants drawn in during the main exhaust fan 17. The filtered air pollutants enter the second filter layer 19 through the second filter screen. Since the activated carbon filled in the second filter layer 19 absorbs harmful gases and water vapor such as organic hydrocarbons, SO2, NO2, and O3 in the air pollutants.

[0055] The wavy first filter separates the first filter layer 18 and the second filter. In this embodiment, the first filter is designed to be wavy, which increases the contact area between the first filter and the first filter layer 18, as well as the contact area between the first filter and the second filter layer 19. The first filter can block fine particles in the air pollutants. Therefore, the air pollutants pass through the second filter layer 19 and then through the first filter to enter the first filter layer 18. The neutral desiccant filled in the first filter layer 18 filters and adheres the gas that has been absorbed by the activated carbon to obtain a combustion-supporting gas containing oxygen.

[0056] Meanwhile, in this embodiment, the air pollutants pass through fine filter cotton, activated carbon, and neutral desiccant in sequence, so that most of the harmful gases inside the air pollutants can be removed to obtain oxygen-containing combustion-supporting gas. The oxygen-containing combustion-supporting gas can be reused to control the increase in the combustion flame of combustibles in the combustion basin 4, thereby realizing the fire extinguishing test of the large-space fire cannon with increased combustion flame.

[0057] Combination Figure 3 As shown, a receiving space 5 for accommodating the gas supply and combustion-supporting structure is provided in the test basin 2. The gas supply and combustion-supporting structure includes a gas supply box 6 set in the receiving space 5. The gas supply box 6 is arranged around the test basin 2. The bottom of the gas supply box 6 has four main gas pipes 24 that surround the exhaust box 16. The two ends of each main gas pipe 24 are connected to the sides of the gas supply box 6 and the exhaust box 16, respectively. The top of the gas supply box 6 has several branch gas pipes 25 that surround the recovery basin 1. The two ends of each branch gas pipe 25 are connected to the gas supply box 6 and the holding tank, respectively. A control valve 26 is installed in the branch gas pipe 25.

[0058] The chamber in the test basin 2 described in the above embodiment is used to accommodate the gas supply and combustion-supporting structure, so that there is a certain distance between the gas supply and combustion-supporting structure and the holding tank. This can reduce the heat generated by the combustion of combustibles in the holding tank from affecting the gas supply and combustion-supporting structure. At the same time, based on the suction process of the main exhaust fan 17, the combustion-supporting gas in the exhaust box 16 is drawn and transported to the gas supply box 6 through the main gas pipe 24, so that the gas supply box 6 can store the combustion-supporting gas. When the combustion-supporting gas is needed, the control valve 26 of the branch gas pipe is opened to transport the combustion-supporting gas in the gas supply box 6 to the holding tank, so that the combustion-supporting gas can assist the combustion of combustibles in the holding tank.

[0059] Furthermore, since there are four main gas pipes 24 between the gas supply box 6 and the extraction box 16 in this embodiment, and the four main gas pipes 24 are arranged around the extraction box 16 in different directions towards the gas supply box 6, under the suction of the main exhaust fan 17, the combustion-supporting gas in the extraction box 16 is transported to the gas supply box 6 through the main gas pipes 24 in different directions. When the combustibles in the holding tank need to be assisted in combustion, the control valve 26 is opened, so that the combustion-supporting gas in the gas supply box 6 is transported to the holding tank through the branch gas pipes 25 surrounding the recovery basin 1. The evenly distributed branch gas pipes provide uniform combustion support to the combustibles in the holding tank, which can achieve complete combustion of the combustibles and increase the fire intensity, thereby enabling the fire extinguishing test of the large-space fire monitor.

[0060] Meanwhile, a combustion-supporting arch bridge plate 3 with an arched longitudinal section is provided between the top of the test basin 2 and the top of the firing basin 4. The combustion-supporting arch bridge plate 3 has a circular structure and surrounds the test basin 2 and the firing basin 4. The bottom of the outer ring of the combustion-supporting arch bridge plate 3 is fixed to the top of the test basin 2, and the bottom of the inner ring of the combustion-supporting arch bridge plate 3 is fixed to the top of the firing basin 4. Several air supply holes 8 are opened on the combustion-supporting arch bridge plate 3 along its circumferential direction. All air supply holes 8 are connected to the corresponding branch gas pipes 25. All air supply holes 8 surround the periphery of the firing basin 4 and face the holding trough.

[0061] In the above embodiment, the combustion-supporting arch bridge plate 3 connects the test basin 2 and the combustion basin 4, so that the test basin 2 can form a receiving space 5 for accommodating the gas supply and combustion-supporting structure, and can also serve as a direction for guiding the delivery of combustion-supporting gas. The gas supply holes 8, which are evenly distributed on the combustion-supporting arch bridge plate 3 along its circumferential direction, deliver the combustion-supporting gas in the branch gas pipe 25 to the corresponding gas supply holes 8. The combustion-supporting gas is then injected into the holding tank of the combustion basin 4 through the gas supply holes 8. Since the gas supply holes 8 are evenly distributed on the combustion-supporting arch bridge plate 3, the combustion-supporting gas can be evenly injected into the combustibles in the holding tank, so that the combustibles can burn evenly and completely, increasing the fire intensity.

[0062] See Figure 2 and Figure 3As shown, a heat insulation layer 13 is attached to the lower surface of the firing basin 4. The periphery of the heat insulation layer 13 extends toward the combustion-supporting arch bridge plate 3 and is arranged on the lower surface of the combustion-supporting arch bridge plate 3. Corresponding through holes are opened on the heat insulation layer 13 to the liquid inlet hole 12 of the holding tank and the air supply hole 8 of the combustion-supporting arch bridge plate 3. The heat insulation layer 13 is made of rubber and plastic heat insulation material.

[0063] The insulation layer 13 in the above embodiment can keep the combustibles in the holding tank of the combustion basin 4 warm, so that the combustion temperature of the combustibles in the holding tank is maintained for a period of time. This can more effectively achieve the effect of testing fire cannons in large spaces. At the same time, the insulation layer 13 in this embodiment is made of rubber and plastic insulation material, so the insulation layer 13 has good elasticity and shock resistance. The insulation layer 13 can effectively mitigate the impact generated by the fire cannon spraying water into the holding tank in a large space. In addition, the through holes opened on the insulation layer 13 correspond to the liquid inlet hole 12 of the holding tank and the air supply hole 8 of the combustion-supporting arch bridge plate 3, so that the liquid inlet hole 12 is connected to the liquid storage tank 14 and the air supply hole 8 is connected to the holding tank.

[0064] See Figure 4 As shown, in this embodiment, the sensing element includes a raised ball 9 embedded in the bottom of the holding tank. The upper part of the raised ball 9 protrudes from the bottom of the holding tank, and the lower part of the raised ball 9 passes through the holding tank and is located in the adjustment basin 2. A heat insulation layer is provided on the outer surface of the lower part of the raised ball 9. The heat insulation layer is made of polyurethane foam. Several temperature sensors 28 are evenly distributed on the outer surface of the heat insulation layer. It also includes a microprocessor, which is electrically connected to the temperature sensors 28, the gas supply and combustion structure and the pollutant recovery structure, respectively.

[0065] In the above embodiment, the upper part of the raised ball 9 protrudes from the bottom of the holding tank, so that the combustion heat of the combustible material in the holding tank is transferred to the position of the heat insulation layer through the lower part of the raised ball 9. Since the heat insulation layer is made of polyurethane foam, the characteristics of polyurethane foam, such as closed-cell microporous foam and low thermal conductivity, are used to greatly reduce the combustion heat transferred by the raised ball 9, thereby reducing the impact of combustion heat on the operation of the main servo motor 7 located below the raised ball 9. At the same time, the temperature sensor 28 set on the outer surface of the heat insulation layer can detect the reduced combustion temperature information of the raised ball 9 and transmit the combustion temperature information to the microprocessor, so that the microprocessor can obtain the combustion temperature value of the combustible material in the holding tank.

[0066] Meanwhile, a preset value is set in the microprocessor. When the combustion temperature value is greater than the preset value, it meets the fire extinguishing test requirements of the large-space fire cannon. At the same time, the microprocessor issues an instruction to activate the pollutant recovery structure, so that the large-space fire cannon can recover pollutants in the surrounding fire extinguishing environment during the fire extinguishing process. In fact, the microprocessor issues instructions to activate the secondary servo motor 22 and the main servo motor 7 of the pollutant recovery structure in sequence. Activating the secondary servo motor 22 can recover the fire extinguishing environment pollutants in the surrounding environment, and activating the main servo motor 7 can separate air pollutants and solid-liquid mixed pollutants in the fire extinguishing environment pollutants.

[0067] Conversely, when the combustion temperature is lower than the preset value, the microprocessor issues a command to activate the gas supply and combustion-supporting structure to supply combustion-supporting gas to the combustibles in the holding tank, so that the combustion temperature of the combustibles in the holding tank reaches the preset value in the microprocessor. Then, a fire extinguishing test can be performed on the large space fire cannon. In practice, the microprocessor activates the control valve 26 in the gas supply and combustion-supporting structure. When the main servo motor 7 is started, it can adsorb and sieve air pollutants to obtain combustion-supporting gas and store it in the gas supply box 6. By opening and closing the control valve 26, the combustibles in the holding tank can be periodically assisted in combustion.

[0068] Meanwhile, in this embodiment, liquid storage tanks 14 are respectively provided on both sides of the heat insulation layer and located on the top surface of the vacuum box 16. The bottom of the holding tank is provided with a liquid inlet hole 12 extending toward the liquid storage tank 14. A drain hole 15 is provided on the side of the liquid storage tank 14. The drain hole 15 is connected to the input hole on the side of the storage box 21 through a pipe.

[0069] During the fire extinguishing process of the large-space fire cannon spraying water, the water will be sprayed into the holding tank. Therefore, the liquid inlet hole 12 at the bottom of the holding tank can introduce the water into the storage tank 14 below the holding tank, realizing the recovery of the water in the holding tank. In addition, since there are two storage tanks 14 located on both sides of the heat insulation layer, the water will absorb the heat of the space during the heat conduction process of the heat insulation layer, reducing the heat generated by the combustion of combustibles from affecting the operation of the main servo motor 7, and also cooling the heat generated by the operation of the main servo motor 7. Furthermore, in this embodiment, the drain hole 15 on the side of the storage tank 14 and the input hole on the side of the storage tank 21 are connected by a pipe, thereby realizing the introduction of the water recovered in the storage tank 14 into the storage tank 21, and the water recovered in the storage tank 21 is discharged through the drain outlet.

[0070] See Figure 5 As shown, a dynamic intelligent adjustment device for recovering environmental pollutants from fire extinguishing is applied in an airport terminal. The method of using this device in an airport terminal includes: Step 1: The tester places combustible material in the holding tank of the firing basin 4 and ignites the combustible material in the holding tank, so that the combustible material burns in the holding tank; Step 2: After the tester completes the ignition operation in Step 1, the sensing element in the holding tank senses the combustion temperature information of the combustibles and obtains the combustion temperature value. Simultaneously, the pollutant recovery structure of the recovery basin 1 is activated, so that the pollutant recovery structure can recover pollutants from the surrounding environment. Step 3: In step 2, when the combustion temperature value is equal to or greater than the preset value in the microprocessor, the tester will start the large space fire cannon to extinguish the combustibles in the combustion basin 4. At the same time, the pollutant recovery structure will continuously recover the fire extinguishing environmental pollutants in the surrounding environment and separate the air pollutants and solid-liquid mixed pollutants in the fire extinguishing environmental pollutants through the separation component. Step 4: In step 2, when the combustion temperature is less than the preset value in the microprocessor, the microprocessor sends an instruction to start the gas supply and combustion-supporting structure of the debugging basin 2. The gas supply and combustion-supporting structure draws in air pollutants and adsorbs and sieves them to obtain combustion-supporting gas, and controls the combustion-supporting gas to be transported toward the combustion basin 4 so that the combustion temperature of the combustible is equal to or greater than the preset value in the microprocessor. Then, the steps of step 3 are repeated.
