[0028] Working principle: When the exhaust gas is treated, the air inlet electric valve 21 is opened. At this time, the exhaust gas is introduced into the inner bottom of the main tower body 1 through the air inlet channel 2 and continues to rise. At the same time, when it rises through the packing layer 12, the spray system 13 continuously sprays and purifies the exhaust gas under the action of the circulating water pump 16.

At the same time, the intelligent digital display PH sensor 151 is set to monitor the pH value inside the circulating water tank 15 in real time. When the limit value is exceeded, the intelligent digital display PH sensor 151 sends an electrical signal to the controller 41. At this time, under the action of the controller 41, the liquid inlet electric valve 155 located on the liquid inlet pipe 154 is opened, and the solvent in the acid agent addition bottle 152 or the alkali agent addition bottle 153 is added to the inside of the circulating water tank 15. At the same time, under the action of the stirring motor 156, the stirrer mixes and stirs it, and automatically stops the liquid inlet and mixing and stirring when the limit value is reached. The pH value inside the circulating water tank 15 can be monitored in real time, and the acid or alkali agent can be added in time, thereby effectively preventing the crystallization nozzle from being blocked due to untimely addition.
