7) gas exhausted from the primary exhaust port (12) enters the secondary washing tower (2) from the secondary air inlet (21), the step 2-5 is repeated, and secondary exhaust gas treatment is carried out on the exhaust gas;

8) the gas treated by the secondary waste gas treatment is detected by an air detector at the secondary exhaust port (22) and is qualified, the purified air is discharged into the air from the secondary exhaust port (22) and is unqualified, and the gas enters the secondary air inlet (21) through an exhaust pipeline and is subjected to secondary waste gas treatment until the gas is qualified and reaches the emission standard;

9) after the washing liquid wastewater in the water storage tanks (3) of the first-stage washing tower (1) and the second-stage washing tower (2) is stored to a certain amount, the wastewater is discharged into a wastewater treatment mechanism (8) through a water pump (7) and a drainage pipeline for wastewater treatment;

10) the wastewater enters a centrifugal separator (81), solid-liquid separation is carried out through the centrifugal separator (81), the wastewater after primary purification enters a filtering device (82), and the purified water after filtration through the filtering device (82) is discharged into a water tank (83); simultaneously, the mud separated by the centrifugal separator (81) and the solid impurities filtered by the filtering device (82) are discharged into a sludge treatment device (84) for sludge treatment;

11) during spraying, the PH value of the waste gas in the detection tower of the PH detector is used, the control system controls the flow of the water pool (83) and the dosing barrel (92) through the detection value, and the proportion of the washing liquid in the reaction kettle (91) is set, so that the spraying effect is optimal;

12) the cleaning solution prepared in the reaction kettle (91) is sent to the spraying device (5) for recycling through the circulating pipeline (93).
