The collection equipment is equipped with high-precision temperature and humidity sensors and barometric pressure sensors to monitor the initial state of the cold air in real time. S2: The collected cold air passes through a multi-stage filtration system. First, the cold air enters a particulate filter to remove particles with a diameter greater than 0.3 micrometers. Then, it passes through an aerosol filter, which uses electrostatic adsorption to remove aerosol particles with a diameter less than 0.3 micrometers. Finally, it passes through a chemical adsorption filter, which uses activated carbon to adsorb harmful chemicals in the air, ensuring that the impurity content in the cold air is less than 0.01%. S3, the filtered cold air enters the heat exchanger, where it exchanges heat with an external heat source through thermally conductive materials, maintaining its temperature within the range of -50℃ to -10℃. The heat exchanger is made of high-efficiency thermally conductive materials to ensure the accuracy and stability of temperature regulation. A temperature sensor monitors the temperature of the cold air in real time and feeds the data back to the control module. The specific steps for regulating the heat exchanger are as follows: Set the target temperature Tset = -30℃ = -30℃.

[0020] Initialize PID parameters: Kp = 2.0; Ki = 0.5; Kd = 1.0, where Kp is the proportional coefficient, Ki is the integral coefficient, and Kd is the derivative coefficient. Initialize variables: integral = 0, e(t-1) = 0 The current temperature (Tactual = -35℃) is collected by a temperature sensor; the current error is calculated. e(t)=Tset-Tactual=-30℃-(-35℃)=5℃ Calculate the output of the PID controller, including the proportional term: P=Kp e(t) = 2.0 5=10 Cumulative error: integral = integral + e(t) T=0+5 1=5 Integral term: I=Ki integral=0.5 5 = 2.5 Error change rate: Differential term: PID output: Based on PID output Increase the power of the heat exchanger to raise the temperature.

[0021] Repeat the above steps, continuously monitoring and adjusting the temperature until the actual temperature stabilizes at around -30℃. S4. Temperature-regulated cold air enters a multi-stage compressor, where its pressure is gradually increased using variable frequency control technology, maintaining it within the range of 0.5 to 2 atmospheres. A pressure sensor monitors the cold air pressure in real time and feeds the data back to the control module. Specifically, when filtered cold air is introduced into the compressor inlet, the pressure sensor collects the cold air pressure value in real time and sets it as "Patual," calculating the difference between the current pressure and the target pressure. e(t) = Pset - Patual Pset: Target pressure.

[0022] Input the pressure error e(t) into the PID controller to calculate the inverter output frequency adjustment: Adjust the inverter output frequency according to Δf: fnew=fcurrent+Δf The inverter output frequency fnew directly controls the motor speed. N= N: Motor speed; f: Inverter output frequency; P: Number of pole pairs of the motor (usually 2 or 4); S5, the neutralization reaction module, introduces regulated cold air into the neutralization reactor, where neutralization occurs through a catalytic reaction. The reactor is equipped with temperature and pressure monitoring devices. Nitrogen oxides (NOx) are neutralized within the reactor. x The reduction reaction of ) is: 4NO + 4NH3 + O2 4N2 + 6H2O Oxidation of carbon monoxide (CO) and hydrocarbons (HC): 2CO+O2 2CO2 C3H8+5O2 3CO2 + 4H2O Oxidation of sulfur dioxide (SO2): 2SO2+O2 2SO3; SO3 is subsequently converted into sulfuric acid; Each sensor monitors the temperature and pressure inside the reactor in real time and feeds the data back to the control module; S6: The temperature sensor monitors the temperature inside the reactor in real time, the pressure sensor monitors the pressure inside the reactor in real time, and the chemical substance concentration sensor monitors the chemical substance concentration in the cold air in real time. The monitored data will be transmitted to the control module in real time. S7, the control module receives data from various sensors. If the temperature is too high, the control module reduces the power of the heat exchanger; if the pressure is insufficient, the control module increases the compression ratio of the compressor. S8 releases the neutralized cold air to the target area through an adjustable nozzle. The nozzle angle and opening can be precisely adjusted according to the needs of the target area.
