[0022] Working principle: First, the boiler exhaust gas enters the box 17 pretreatment unit through the interface two 19. Here, inertial separation and semiconductor refrigeration are carried out simultaneously: the former separates large particle dust through airflow change and gravity to achieve primary physical dust removal; the latter simultaneously reduces the exhaust gas temperature to cause water vapor to be cold-drawn, effectively reducing the exhaust gas humidity and subsequent processing load. Subsequently, the airflow enters the spray zone in the box 17 and is preliminarily washed by the spray system driven by the circulating pump two 22, further removing pollutants. After completing the pretreatment, the exhaust gas enters the main treatment tank body 1 through the interface one 18.
[0023] In the tank body 1, the exhaust gas first enters the core turbulent treatment area. The area is constructed by a storage frame 5 filled with turbulent spheres 6 to build a reinforced reaction field. The external ultrasonic vibrator 7 introduces high-frequency vibration to excite strong “ultrasonic cavitation effect”, using the microcosmic shock wave of cavitation bubble rupture to perform acoustic condensation on the fine particulate matter and accelerate chemical reactions. At the same time, the turbulent spheres 6 roll violently under the action of airflow to form efficient three-phase turbulent flow, ensuring sufficient contact between gas and liquid.
[0024] The airflow treated by the turbulent flow enters the spiral guide area immediately. The three triangularly distributed spiral cylinders 3 forcibly guide the airflow to produce orderly rotation, realizing deep mixing and mass transfer of gas and liquid through the extension of the movement path and the action of centrifugal force.
[0025] Finally, the fully mixed airflow enters the spray reaction area at the top of the tank body 1. The circulating pump one 8 pumps the treatment liquid to the top to form a dense liquid curtain for the final thorough washing of the rotating airflow. The purified gas is discharged from the gas outlet 12, and the built-in gas sensor monitors the emission data in real time and feeds back to the control panel 15, forming intelligent closed-loop control to ensure long-term, stable and efficient operation of the system.
