Description

Technical Field

[0001] The present invention belongs to the technical field of air pollution control, and in particular relates to air pollution control equipment and a control method thereof. Background Art

[0002] In the field of air pollution control, pollutants such as dust, PM2.5, and acidic gases generated by human activities such as industrial production and urban transportation will continue to rise in concentration if they are not promptly naturally settled or purified, causing serious harm to the ecological environment and human health. Currently, the wet treatment technology of "liquid spraying" is often used to control pollution sources such as dust and industrial waste gas. This technology uses a spray device to atomize water or chemical solutions into droplets, and then uses the collision and adsorption of droplets with pollutants to achieve purification. The core of this technology is to improve the gas-liquid contact efficiency by optimizing the droplet characteristics (such as particle size and concentration) to meet the treatment needs of different pollution scenarios.

[0003] Existing air pollution control equipment has different dust distribution in the air due to different places of use. The concentration is high in some areas and more dispersed in others. The existing fixed spray heads can only produce droplets of a single particle size and cannot dynamically adjust the droplet characteristics according to the dust concentration and particle size distribution (such as the coexistence of PM2.5 and coarse dust). As a result, in areas with high pollution loads, the droplet size is too large or too small, making it difficult to efficiently capture fine particles or neutralize gaseous pollutants. In areas with dispersed pollution, there is a problem of excessive droplet spraying and energy waste. Summary of the Invention

[0004] The purpose of the present invention is to provide an atmospheric pollution control device and a control method thereof, so as to solve the problems of low pollutant capture efficiency, serious waste of energy and reagents, and difficulty in coping with complex pollution loads caused by the insufficient droplet control ability and adaptability of existing wet treatment equipment to pollution scenes.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] An air pollution control device and a control method thereof, comprising:

[0007] The hood is connected to the air conditioner by means of a vent, and the vent is connected to the air conditioner by means of a vent.

[0008] Preferably, the top of the fan box body is fixedly connected to a return air duct, the output end of the return air duct is fixedly connected to an air inlet pipe, and the output end of the air inlet pipe is connected to the interior of the small chamber box, a flow meter is provided on the outer wall of the return air duct, and an air outlet is opened on one side of the outer wall of the return air duct.

[0009] Preferably, the air inlet of the small chamber box is equipped with a surface cooler, whose function is to reduce the temperature of the polluted air and control it within the temperature difference range of 0 to -2°C with the indoor temperature. The outlet end of the small chamber box is equipped with a temperature and humidity transmitter, whose function is to monitor the temperature and humidity of the treated air and serve as a basis for controlling the wet balance. The main frame of the small chamber box itself is made of aluminum alloy profiles, and the wall panels are 8mm thick aluminum-plastic panels, the floor surface is a stainless steel plate, and the transparent part is 8mm thick tempered glass.

[0010] Preferably, the computer module body serves as the control center, which is equipped with a solid-state drive, 8G memory, etc., and is equipped with two displays. One of the displays monitors the pollution control parameters and adjusts the dosage of the atomizer and salt sprayer in real time. The other is a camera monitoring screen that can control the camera. The desktop material is stainless steel plate and the frame is aluminum alloy profile.

[0011] Preferably, the upstream section connecting pipeline forces the polluted air and the treatment liquid to be mixed through a built-in atomizing nozzle, the upstream section connecting pipeline and the installation section connecting pipeline are locked by a locking cylinder, and a sealing airbag is used to ensure sealing at the connection between the two. The installation section connecting pipeline is used to install a multi-stage gas-liquid contact filter element, and this pipe section can rotate clockwise and counterclockwise, and the pipe section itself is made of tempered glass for easy observation.

[0012] Preferably, the function of the downstream section connecting pipeline is to fully separate the pollutant droplets from the air, and this pipe section can be manually rotated clockwise or counterclockwise, and the connection between the installation section connecting pipeline and the downstream section connecting pipeline is achieved by locking the cylinder, and the sealing airbag is arranged between the two to ensure sealing performance.

[0013] Preferably, the terminal section connecting pipeline is used to install a terminal filter and a grid to collect waste liquid containing particulate matter, and the grid is used to intercept unseparated droplets.

[0014] Preferably, the fan box body is used to house the fan therein, thereby playing a sound insulation role to reduce the fan noise from being transmitted outward.

[0015] Preferably, the return air duct is equipped with an exhaust valve and an exhaust duct. In the direct exhaust mode, the straight duct air valve is closed, and the treated gas that meets the standards is discharged from the air outlet. The straight duct air valve dynamically adjusts the opening according to the pollution load, and the air inlet is equipped with four high-efficiency filters with large air volume. A multi-leaf air valve is installed behind the four high-efficiency filters. When using circulating air, the air valve is closed.

[0016] Preferably, the bracket body itself is made of 8080 aluminum alloy profile, and a high-precision guide rail is installed inside to facilitate the forward and backward movement of each pipe section.

[0017] A method for controlling air pollution, using the air pollution control device described above, comprises the following steps:

[0018] Step 1: Preset the treatment target parameters (including pollutant removal rate, droplet size range and agent concentration) through the computer module body, and start the atomizer, salt sprayer, humidifier and fan box body to allow polluted air to enter the system through the air inlet;

[0019] Step 2: The polluted air first flows into the small chamber and is initially mixed with the atomized droplets to complete the capture of coarse dust particles and neutralization of acidic gases. It then enters the upstream connecting pipeline and forms a forced swirl through the turbulence enhancement module to improve the PM2.5 adsorption efficiency. Finally, it flows into the installation section connecting pipeline and passes through the liquid membrane filter cartridge of the rotatable exchange module to deeply remove VOCs and NO. x and other gaseous pollutants;

[0020] Step 3: After the entrained liquid droplets are removed by the gas-liquid separation component of the downstream connecting pipeline, the clean air is further purified by the high-efficiency filtration unit of the terminal connecting pipeline and meets the emission standards;

[0021] Step 4. The computer module body collects data from the micro-differential pressure sensor and the temperature and humidity sensor in real time, and dynamically adjusts the number of atomizer nozzles opened and the amount of salt spray agent added. When it is detected that the treatment module is saturated or the waste liquid level is abnormal, the cylinder drive mechanism is triggered to switch to the backup module. At the same time, the polluted waste liquid is transported to the regeneration system for recycling through the active liquid pump.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] (1) The atomizer sprays droplets to capture particulate matter, and the salt sprayer releases chemicals to neutralize acidic gases, achieving PM2.5 and SO2 / NO x It can simultaneously remove pollutants such as industrial waste gas and urban dust, adapt to complex pollution scenarios such as industrial waste gas and urban dust, and overcome the limitations of the single governance mechanism of traditional equipment.

[0024] (2) Through real-time analysis of pollution loads by computer modules, dynamic adjustment of atomized droplet size and reagent dosage, and combined with feedback from temperature and humidity transmitters to maintain optimal gas-liquid contact efficiency, a "perception-optimization-control" closed loop is formed, significantly improving the stability of pollutant removal.

[0025] (3) Through the full pipeline sealing airbag and funnel-shaped waste liquid recovery design, zero leakage of waste liquid containing particulate matter is ensured. At the same time, the rotating pipe segment locking structure maintains the high-pressure airtightness of the gas-liquid reaction chamber, eliminating secondary pollution and complying with the operating specifications of environmental protection equipment.

[0034] Example 1:

[0035] See also Figure 1-Figure 5 As shown, an air pollution control device and a control method thereof include:

[0036] The small chamber box 1, one side of the outer wall of the small chamber box 1 is fixedly connected with the upstream section connecting pipe 2, the front end of the small chamber box 1 is placed with an atomizer 3, one side of the outer wall of the atomizer 3 is placed with a salt sprayer 4, and the output ends of the atomizer 3 and the salt sprayer 4 are both connected to the interior of the small chamber box 1, and the other side of the outer wall of the small chamber box 1 is fixedly connected with a humidifier 5, one side of the outer wall of the upstream section connecting pipe 2 is in contact with the computer module body 6, one side of the outer wall of the upstream section connecting pipe 2 is fixedly connected with the installation section connecting pipe 7, one side of the outer wall of the installation section connecting pipe 7 is fixedly connected with the downstream section connecting pipe 8, one side of the outer wall of the downstream section connecting pipe 8 is fixedly connected with the terminal section connecting pipe 9, one side of the outer wall of the terminal section connecting pipe 9 is fixedly connected with the fan box body 10, and one side of the outer wall of the fan box body 10 is fixedly connected with the electrical cabinet 11, a bracket body 12 is fixedly connected between the bottom of the upstream section connecting pipe 2, the installation section connecting pipe 7 and the downstream section connecting pipe 8, and the terminal section connecting pipe 9 is movably arranged on the top of the bracket body 12.

[0037] Depend on Figure 1-Figure 4It can be seen that the top of the fan box body 10 is fixedly connected to the return air duct 14, the output end of the return air duct 14 is fixedly connected to the air inlet pipe 13, and the output end of the air inlet pipe 13 is connected to the interior of the small chamber box 1, a flow meter 15 is set on the outer wall of the return air duct 14, and an air outlet 16 is opened on one side of the outer wall of the return air duct 14.

[0038] As can be seen from the above, when the equipment is in use, the target parameters for treatment, such as the PM2.5 threshold, SO2 neutralization rate, etc., are set inside the computer module body 6. At the same time, the composite filter element loaded with the treatment agent is installed, and all the equipment in the device is checked to see if it is in normal operation. According to the set treatment parameters, the atomizer 3 sprays NaOH solution, the salt sprayer 4 releases Na2CO3 droplets, and the humidifier 5 controls the humidity to build a gas-liquid reaction environment. The fan box body 10 drives the polluted air to circulate in the treatment system, and the gas enters the composite filter element through the small chamber box 1. The liquid film on its surface captures particulate matter and neutralizes acidic pollutants. At the system outlet, the pollutant concentration sensor monitors the quality of the treated air in real time, and the data is fed back to the computer module body 6 to dynamically adjust the dosage of the agent, and calculate the pollutant removal rate and the emission compliance status.

[0039] Example 2:

[0040] refer to Figure 1-Figure 5 As shown, one side of the outer wall of the small chamber box 1 is fixedly connected with an upstream section connecting pipe 2, an atomizer 3 is placed on the front end of the small chamber box 1, and a salt sprayer 4 is placed on one side of the outer wall of the atomizer 3, and the output ends of the atomizer 3 and the salt sprayer 4 are both connected to the interior of the small chamber box 1, and the other side of the outer wall of the small chamber box 1 is fixedly connected with a humidifier 5, one side of the outer wall of the upstream section connecting pipe 2 is in contact with a computer module body 6, one side of the outer wall of the upstream section connecting pipe 2 is fixedly connected with an installation section connecting pipe 7, one side of the outer wall of the installation section connecting pipe 7 is fixedly connected with a downstream section connecting pipe 8, one side of the outer wall of the downstream section connecting pipe 8 is fixedly connected with a terminal section connecting pipe 9, and the terminal section One side of the outer wall of the connecting pipe 9 is fixedly connected to the fan box body 10, and one side of the outer wall of the fan box body 10 is fixedly connected to the electrical cabinet 11. The bottom of the upstream section connecting pipe 2, the installation section connecting pipe 7 and the downstream section connecting pipe 8 is fixedly connected with the bracket body 12, and the terminal section connecting pipe 9 is movably set on the top of the bracket body 12. The top of the fan box body 10 is fixedly connected to the return air duct 14, and the output end of the return air duct 14 is fixedly connected to the air inlet pipe 13, and the output end of the air inlet pipe 13 is connected to the interior of the small chamber box 1. A flow meter 15 is provided on the outer wall of the return air duct 14, and an air outlet 16 is provided on one side of the outer wall of the return air duct 14;

[0041] The air inlet of the small room box 1 is equipped with a surface cooler, whose function is to reduce the temperature of the polluted air and control it within the temperature difference range of 0 to -2°C with the indoor temperature. The outlet end of the small room box 1 is equipped with a temperature and humidity transmitter, whose function is to monitor the temperature and humidity of the treated air and serve as the basis for controlling the wet balance. The main frame of the small room box 1 itself is made of aluminum alloy profiles, and the wall panels are 8mm thick aluminum-plastic panels, the floor surface is stainless steel, and the transparent part is 8mm thick tempered glass. The computer module body 6 serves as the management control center, which is equipped with a solid state drive, 8G memory, etc., and is equipped with two monitors, one of which is a monitor Monitor pollution control parameters and adjust the dosage of the atomizer 3 and the salt sprayer 4 in real time. The other is a camera monitoring screen, which can control the camera. The desktop material is made of stainless steel plate and the frame is made of aluminum alloy profile. The upstream section connecting pipe 2 forces the polluted air and the control liquid to be mixed through the built-in atomizing nozzle. The upstream section connecting pipe 2 and the installation section connecting pipe 7 are locked by a locking cylinder, and a sealing airbag is used to ensure the seal at the connection between the two. The installation section connecting pipe 7 is used to install a multi-stage gas-liquid contact filter element, and this pipe section can be rotated clockwise and counterclockwise, and the pipe itself is made of tempered glass for easy observation.

[0042] As can be seen from the above, first of all, in order to control the temperature difference between the inside and outside of the small chamber box 1 at 0 to -2 ° C to avoid condensation on the pipe wall in the treatment area, the small chamber box serves as a gas-liquid reaction buffer cabin to make the humidity of the polluted air entering the pipeline uniform, and integrates the treatment unit (atomizer, drug injector, etc.);

[0043] The computer module body 6 is equipped with two displays, one of which monitors the pollution control parameters and adjusts the dosage of the atomizer 3 and the salt sprayer 4 in real time, and the other is a camera monitoring screen, such as starting, stopping recording, taking pictures, etc.

[0044] An upstream pressure monitoring loop is installed inside the upstream connecting pipe 2 to monitor the dynamic pressure of the polluted airflow in the gas-liquid reaction section in real time. Together with the downstream pressure measurement loop, it is connected to a micro-differential pressure sensor, which uses the change in airflow resistance to feedback the gas-liquid reaction efficiency of the system (the resistance value indirectly reflects the collision and coagulation degree between droplets and pollutants, guiding the optimization of atomization parameters). To prevent the backflow of polluted waste liquid (the treatment liquid after capturing pollutants) from interfering with the monitoring and treatment process, the lower part of the measurement loop pipeline adopts a design without sampling holes; it is also equipped with an internal self-cleaning device to automatically remove residual polluted liquid and incompletely captured ultrafine particles, ensuring the accuracy of the system's operating resistance data and preventing pollutants from corroding the sensor.

[0045] This section reserves the water mist particle size online monitoring interface and the pollutant concentration real-time analysis interface (the original water mist particle size analyzer and ion chromatograph interface function upgrade):

[0046] Water mist particle size interface: real-time collection of the particle size of the treated droplets to ensure the optimal collision adsorption particle size match between the droplets and pollutants such as PM2.5 and aerosols;

[0047] Ion chromatograph interface: online detection of SO2 and NO in air flow x The concentration of acidic gases is adjusted intelligently, and the amount and composition of the chemical solution added to the salt sprayer 4 are adjusted (for example, automatically switching to a high-concentration NaOH solution when pollution peaks).

[0048] Liquid collection baffles are installed on both sides of the section body. In the droplet capture operation mode, they prevent the spread of polluted waste liquid in the upstream section and guide the waste liquid along the slope of the funnel-shaped lower plate to the outlet, where it is discharged to the waste liquid regeneration system through a ball valve. An active liquid extraction pump is also configured: Because pollution control requires continuous operation 24 hours a day, 7 days a week, excessive polluted liquid in the pipeline may flow back into the downstream treatment unit, resulting in reagent waste or unit blockage. The liquid extraction pump overcomes the negative pressure in the pipeline and actively pumps the waste liquid to the waste liquid collection tank (real-time measurement of pollutant capture, assisting in environmental emission accounting), ensuring the continuous and stable operation of the multi-stage treatment unit.

[0049] The upstream connecting pipeline 2 is integrated and installed through an aluminum profile bracket and is equipped with a height adjuster. It can flexibly adapt the air flow inlet height according to the pollution scenario (such as industrial chimney interface, urban air purification tower), and enhance the flow field matching between the gas-liquid reaction section and the front-end polluted gas source (for example, industrial high-concentration exhaust gas requires more intense gas-liquid turbulent mixing, and the flow channel design is optimized through height adjustment).

[0050] The installation section connecting pipe 7 serves as the modular chamber replacement and liquid film purification center for air pollution control. Its bidirectional rotating cylinder controls the clockwise / counterclockwise rotation of the pipe section through buttons on both sides, quickly opening the chamber replacement ports of the air inlet and air outlet side treatment modules - the air inlet side is adapted to the coarse dust interception filter element (to avoid clogging the subsequent liquid film), and the air outlet side is integrated with a liquid membrane purification filter cartridge (relying on droplet adsorption and chemical reaction to synergistically treat fine particles and acidic gases), supporting non-stop module replacement (when the treatment module is saturated / blocked, the switch is completed quickly) to ensure the continuous pollution control process of the system; the lower plate continues the funnel-shaped diversion design to guide the polluted waste liquid carrying pollutants in the treatment process (such as water mist for adsorbing PM2.5 and alkaline solution for neutralizing SO2) to flow to the outlet and discharge into the waste liquid regeneration system through the ball valve (clean water can flow back to the atomizer and the reagent components can be easily regenerated). A new active liquid pump is added to overcome the negative pressure of the pipeline to prevent the waste liquid from backflowing into the treatment module, causing reagent dilution and filter element clogging, and assisting in realizing the basic closed loop of "liquid capture-liquid recovery"; pipe The sections are integrated through aluminum profile brackets, and the height adjuster is adapted to the airflow inlet height of different scenarios such as industrial chimneys and urban purification towers to optimize the gas-liquid reaction process; the guide rail translation mechanism pushed and pulled by the cylinder replaces manual handling to realize the automatic warehouse change of the treatment unit; the cylinder locking plates at both ends are precisely locked with the upstream and downstream pipelines to ensure the fully enclosed operation of the polluted airflow and the treatment liquid (no leakage risk, in line with the sealing requirements of environmental protection facilities); the upper part is equipped with "UV + LED" dual light sources and a movable camera, and UV light assists in observing the distribution trajectory of the treatment droplets in the module and the collision state with pollutants, providing a visual reference for the optimization of droplet parameters; the LED light meets the observation needs of conventional working conditions; the camera records the entire process of "droplet capture of pollutants → waste liquid confluence → filter element purification", providing basic data support for the intelligent control of the system (such as mold change timing, droplet parameter adjustment), and finally through the collaborative design of modular warehouse change, liquid film purification, and waste liquid closed loop, it adapts to the continuous and scenario-based needs of atmospheric pollution control;

[0051] The downstream connecting pipeline 8 is a key link in gas-liquid separation and waste liquid management in atmospheric pollution control. The pipe section can be manually rotated clockwise and counterclockwise to facilitate the maintenance and observation of the internal gas-liquid separation components (the original pressure measurement ring area) - the internal downstream pressure monitoring ring and the upstream monitoring ring are collaboratively connected to the micro-differential pressure sensor to provide real-time feedback on the operating resistance of the polluted air flow after being captured by the liquid film, providing a reference for evaluating the gas-liquid separation efficiency and optimizing the front-end atomization parameters; in order to avoid interference of polluted waste liquid in the monitoring and treatment process, the lower part of the measuring ring pipeline adopts a sampling hole-free design, and the matching internal self-cleaning device can automatically remove residual droplets and particles to ensure the reliability of the system resistance monitoring. The reserved ion chromatograph interface in this section has been transformed into a real-time pollutant composition monitoring inlet, assisting in determining the adequacy of the gas-liquid reaction. During droplet capture operations, the liquid collection baffles on both sides guide the contaminated waste liquid along the funnel-shaped lower plate to the outlet, where it is discharged into the waste liquid recovery system through a ball valve. The original "weighing" function has been optimized for waste liquid volume statistics and initial component screening, providing basic data for reagent regeneration. An active liquid pump overcomes the negative pressure in the pipeline and pumps excess waste liquid to a collection device to prevent backflow from affecting the front-end treatment unit. The pipe section is installed using an aluminum profile bracket, and the height adjuster adapts to the airflow outlet requirements of different scenarios. The built-in cylinder-driven safety valve automatically triggers when abnormal negative pressure occurs in the system, triggering the alarm device and quickly releasing pressure. The manual opening design of the operating surface ensures emergency safety. Internally configured waterproof UV and LED lights assist in observing the state of droplet separation during the treatment process. UV light illuminates droplets containing tracers (instead of sodium fluorescein mist) to visually demonstrate the gas-liquid separation effect. The LED lights, combined with rotatable cameras at the air inlet and outlet, record the entire process of "droplet capture of pollutants → gas-liquid separation → waste liquid discharge." The camera's rotating mechanism avoids potential droplet splashes or particle residue during the treatment process, providing a visual basis for system operation and maintenance (such as separation component cleaning and waste liquid recovery efficiency evaluation). Through the integrated design of gas-liquid separation, waste liquid recovery, safety assurance, and intelligent monitoring, the subsequent treatment process after liquid capture of pollutants is stable and efficient.

[0052] The terminal connecting pipe 9 serves as the terminal purification and waste liquid collection unit for air pollution control. It can move forward and backward along the guide rail under the push-pull action of the cylinder. This design serves the modular operation and maintenance requirements in the control process. During normal operation, it drives the downstream connecting pipe 8 to move synchronously, reserving operating space for the inspection and replacement of the front-end control unit (such as the liquid membrane purification module in the installation section); when it is necessary to strengthen waste liquid interception or deal with special pollution conditions, the terminal high-efficiency filter can be replaced with a grid + medium-efficiency filter assembly, where the grid is used to intercept the residual polluted liquid droplets after gas-liquid separation, and the medium-efficiency filter further absorbs the escaping fine particles to ensure the cleanliness of the final exhaust gas. The moving guide rail mechanism and cylinder drive system of this section continue the original structural design, which not only supports the daily maintenance of the control equipment (such as filter element replacement and waste liquid pipeline cleaning), but also can quickly switch the terminal purification configuration when the pollution load suddenly changes. Through the integrated design of "terminal filtration + waste liquid interception + flexible operation and maintenance", it provides reliable terminal protection for the full process of "liquid capture of pollutants" while ensuring the adaptability and operational stability of the equipment in different pollution scenarios.

[0053] The fan box body 10 may generate vibration during operation. For this reason, a shock absorber is installed between the fan bracket and the ground, and the air inlet and outlet 16 are both softly connected, which can effectively attenuate the vibration transmission during the operation of the fan and avoid interference with the stability of the upstream gas-liquid reaction section, downstream separation section and other treatment units. The box is equipped with an air inlet and an air outlet to reduce the temperature of the fan during operation. The inner wall of the box is equipped with high-quality sound-absorbing cotton to effectively isolate the noise of the fan during operation, making the noise less than 70 decibels. The sound-absorbing box is equipped with an inspection door connected by hinges to facilitate inspection and maintenance of the fan.

[0054] The return air duct 14 is equipped with an exhaust valve and an exhaust duct. When the purified gas meets the standard, the exhaust valve is opened to enter the direct exhaust mode, and the straight pipe air valve is closed to safely discharge the clean air after treatment from the air outlet 16. When the humidity in the pipeline is high (affecting the droplet capture efficiency) or the pollution load increases suddenly, the three valves (exhaust valve, straight pipe air valve, and air inlet valve) are linked to draw fresh air from outside and mix it into the treatment process. On the one hand, the system humidity is reduced to optimize the collision and adsorption effect of droplets and pollutants, and on the other hand, the overall treatment capacity is increased by adding fresh air. Four high-efficiency filters with large air volume are installed at the air inlet, which continuously filter the circulating air with low resistance characteristics to prevent external dust and other impurities from interfering with the effect of treating droplets.

[0055] The bracket body 12 has high overall strength and is stable, and does not require expansion bolts to be driven into the ground;

[0056] The humidifier 5 function uses an ultrasonic humidifier, which saves energy, does not produce condensation, and does not cause temperature rise in the test air, eliminating the interference of abnormal humidity control on the gas-liquid reaction from the source. Different from traditional ultrasonic equipment, this humidifier can increase the humidity of polluted air to a range far higher than that of conventional equipment through the coordinated control of water temperature and water volume, creating the optimal thermodynamic conditions for the collision and adsorption of droplets with pollutants such as PM2.5 and aerosols (the higher the humidity, the higher the efficiency of droplet agglomeration). The device supports real-time communication with the computer module body 6, automatically adjusts the humidification amount according to the concentration of particulate matter in the polluted airflow, and realizes the intelligent matching of "pollution load-humidity parameters"; the built-in automatic water addition, drainage and water purification filtration system ensures the stability of the water source during continuous pollution control, and avoids the attenuation of droplet capture efficiency due to water shortage; the Foma wheel design enables it to be flexibly moved to different scenarios such as industrial waste gas emission outlets and urban air purification stations, and quickly reaches the humidity set value within 10 minutes, providing a stable humidity environment support for the entire process of "liquid capture of pollutants", helping to improve overall treatment efficiency.

[0057] The water volume of the atomizer 3 can be adjusted within a wide range. The compressed air pipeline and the water circuit are equipped with real-time pressure and flow monitoring units to ensure that the water and gas parameters of each branch are accurately matched, so that the droplet particle size sprayed by the built-in 12 binary flow fine atomization nozzles is maintained in an optimized uniform range to enhance the collision adsorption efficiency with pollutants such as PM2.5 and aerosols. The device supports independent control of each water and gas branch on the display screen. It can automatically adjust the number of nozzles working and the flow rate of a single nozzle according to the pollution data (such as particulate matter concentration, gaseous pollutant composition) transmitted by the computer module body 6 without on-site operation. In high-load scenarios of industrial waste gas, the multi-nozzle high-flow mode can be enabled to quickly generate sufficient droplets to capture pollutants; in low-load scenarios such as urban air purification, switch to the at least one nozzle low-flow mode to improve the capture effect of fine particles by reducing the droplet particle size (close to natural mist particles). The multi-configuration nozzle branch design supports flexible adaptation to different pollution conditions, so that the droplet particle size and pollutant distribution are dynamically matched;

[0058] The flow rate of the salt sprayer 4 can be adjusted over a wide range and linked to the computer module of the control center according to the composition of the polluted gas (such as SO2, NO x The concentration) automatically adjusts the dosage of the agent. It is equipped with a salt water bottle and a clean water bottle inside, which automatically switches the cleaning pipeline. The high-precision peristaltic pump is driven by a stepper motor, with accurate flow. The special atomization nozzle has the characteristics of small particle size and low gas consumption, and cooperates with the water mist to form a "physical capture + chemical neutralization" treatment field, which is suitable for the coordinated removal of multiple pollutants under different pollution conditions.

[0059] The ion chromatograph adopts a full-system constant temperature and temperature compensation design, and is equipped with a corrosion-resistant PEEK pump to monitor the pollutant components (such as SO2, NO xion concentration), providing real-time data support for the control of chemical solution dosage, ensuring the accuracy and continuity of the "liquid capture pollutant" process;

[0062] refer to Figure 1-Figure 5 As shown, one side of the outer wall of the small chamber box 1 is fixedly connected with an upstream section connecting pipe 2, an atomizer 3 is placed on the front end of the small chamber box 1, and a salt sprayer 4 is placed on one side of the outer wall of the atomizer 3, and the output ends of the atomizer 3 and the salt sprayer 4 are both connected to the interior of the small chamber box 1, and the other side of the outer wall of the small chamber box 1 is fixedly connected with a humidifier 5, one side of the outer wall of the upstream section connecting pipe 2 is in contact with a computer module body 6, one side of the outer wall of the upstream section connecting pipe 2 is fixedly connected with an installation section connecting pipe 7, one side of the outer wall of the installation section connecting pipe 7 is fixedly connected with a downstream section connecting pipe 8, one side of the outer wall of the downstream section connecting pipe 8 is fixedly connected with a terminal section connecting pipe 9, and the terminal section One side of the outer wall of the connecting pipe 9 is fixedly connected to the fan box body 10, and one side of the outer wall of the fan box body 10 is fixedly connected to the electrical cabinet 11. The bottom of the upstream section connecting pipe 2, the installation section connecting pipe 7 and the downstream section connecting pipe 8 is fixedly connected with the bracket body 12, and the terminal section connecting pipe 9 is movably set on the top of the bracket body 12. The top of the fan box body 10 is fixedly connected to the return air duct 14, and the output end of the return air duct 14 is fixedly connected to the air inlet pipe 13, and the output end of the air inlet pipe 13 is connected to the interior of the small chamber box 1. A flow meter 15 is provided on the outer wall of the return air duct 14, and an air outlet 16 is provided on one side of the outer wall of the return air duct 14;

[0063] The downstream section connecting pipe 8 is used to fully separate the pollutant droplets from the air, and this pipe section can be manually rotated clockwise or counterclockwise, and the connection between the installation section connecting pipe 7 and the downstream section connecting pipe 8 is achieved by locking the cylinder, and a sealing airbag is arranged between the two to ensure sealing performance. The terminal section connecting pipe 9 is used to install the terminal filter and the grille to collect waste liquid containing particulate matter. The grille is used to intercept unseparated droplets. The fan box body 10 is used to install the fan inside it to play a sound insulation role to reduce the fan noise from spreading outward. The return air duct 14 is equipped with an exhaust valve and an exhaust pipe. In the direct exhaust mode, the straight pipe air valve is closed, and the treated gas that meets the standards is discharged from the air outlet 16. The straight pipe air valve dynamically adjusts the opening according to the pollution load, and the air inlet is equipped with four high-efficiency filters with large air volume. A multi-leaf air valve is installed behind the four high-efficiency filters. When using circulating air, the air valve is closed; the bracket body 12 itself is made of 8080 aluminum alloy profile, and a high-precision guide rail is installed inside to facilitate the movement of each pipe section back and forth.

[0064] As can be seen from the above, the control interface adopts a modular design. Each treatment scenario label (such as industrial waste gas and urban dust) corresponds to an independent control interface, which can be switched by clicking the label. The operating resistance-time curve displays the resistance changes of the treatment system in humidity control mode in real time. The curve recording points are triggered by the time interval and the resistance change threshold (which can be customized), which intuitively reflects the operating status of the gas-liquid reaction section. The treatment data recording module supports custom data sampling cycles and performs real-time data averaging on parameters such as system resistance. The data is automatically stored in Excel and generates a treatment report that meets environmental emission requirements.

[0065] Control Surface Integration:

[0066] 1) Target humidity setting: Control the start and stop of the ultrasonic humidifier to create the optimal gas-liquid reaction humidity environment;

[0067] 2) Termination parameters: The system termination resistance value and planned operation time can be preset. If either of the two is met, the system will automatically switch to standby mode;

[0068] 3) Intelligent start-up logic: After clicking "Start Governance", the fan and humidifier start in conjunction, and automatically start recording governance data after the environmental parameters meet the standards;

[0069] 4) Data management function: supports historical data clearing and manual / automatic saving, which facilitates the tracing of governance processes and optimization of operation strategies.

[0070] The mechanism works as follows: Contaminated air enters the system, driven by the fan housing 10. It first flows through chamber 1, where a surface cooler maintains a temperature differential of 0 to -2°C in the gas-liquid contact zone, preventing condensation and ensuring the stability of the atomized droplets. The contaminated air then enters the upstream connecting pipe 2, where it is forcibly mixed with the treatment droplets (e.g., NaOH solution) sprayed by the atomizer 3 and the chemical agent (e.g., Na2CO3 droplets) released by the salt sprayer 4, forming a gas-liquid two-phase flow. This mixed air flows through the multi-stage gas-liquid contact filter element in the installation connecting pipe 7. The liquid film on the filter surface captures particulate matter and removes acidic pollutants through inertial collision and chemical neutralization. Ultraviolet light displays the adsorption trajectory of the pollutants in real time. The pollutant-laden air then enters the downstream connecting pipe 8, where the pollutant droplets are separated from the air. The separated particulate wastewater flows along the funnel-shaped bottom plate to the recovery tank, while the purified air continues to the terminal connecting pipe 9, where a screen intercepts any remaining droplets before it reaches standard discharge. The computer module 6 monitors the treatment status in real time through temperature and humidity transmitters and micro-differential pressure sensors, dynamically adjusting atomization intensity, agent dosage, and humidity in the humidifier 5, forming a closed loop of "pollution load sensing - parameter optimization - enhanced treatment." The return air duct 14 intelligently switches modes based on pollution concentration: directly discharging qualified air during high loads, and closing the multi-leaf damper to enter a recirculation mode during low loads to reduce agent consumption. This ultimately achieves efficient treatment and resource optimization throughout the entire liquid capture process.

[0071] A method for controlling air pollution, using the air pollution control device described above, comprises the following steps:

[0072] Step 1: Preset the treatment target parameters (including pollutant removal rate, droplet size range and agent concentration) through the computer module body 6, and start the atomizer 3, salt sprayer 4, humidifier 5 and fan box body 10 to allow polluted air to enter the system through the air inlet;

[0073] Step 2: The polluted air first flows into the small chamber box 1 and is initially mixed with the atomized droplets to complete the capture of coarse dust particles and neutralization of acidic gases. Then it enters the upstream connecting pipe 2 and forms a forced swirl through the turbulence enhancement module to improve the PM2.5 adsorption efficiency. Finally, it flows into the installation section connecting pipe 7 and passes through the liquid membrane filter cartridge of the rotatable chamber treatment module to deeply remove VOCs and NO. x and other gaseous pollutants;

[0074] Step 3: After the entrained liquid droplets are removed by the gas-liquid separation component of the downstream connecting pipe 8, the clean air is further purified by the high-efficiency filtration unit of the terminal connecting pipe 9 and is discharged in compliance with the emission standards;

[0075] Step 4: The computer module body 6 collects data from the micro-differential pressure sensor and the temperature and humidity sensor in real time, and dynamically adjusts the number of nozzles opened in the atomizer 3 and the dosage of the salt sprayer 4. When it is detected that the treatment module is saturated or the waste liquid level is abnormal, the cylinder drive mechanism is triggered to switch to the backup module, and at the same time, the polluted waste liquid is transported to the regeneration system for recycling through the active liquid pump.
