9. A method of operating an exhaust gas purification system for atmospheric pollution abatement, employing an exhaust gas purification system for atmospheric pollution abatement as claimed in any one of claims 1 to 8, comprising the steps of:

step one: the exhaust emission port of the factory is connected to the cover body (301) of the air inlet pipe (3), the exhaust pipe in the exhaust mechanism (5) is connected to the atmosphere, and in the purifying process, the exhaust enters the air inlet tank (8) from the air inlet pipe (3) firstly, and at the moment, each recovery pipe (802) is closed;

step two: the waste gas entering the air inlet tank (8) is firstly subjected to the air inlet effect of the blast pipe (803), the waste gas is diluted and floats upwards, firstly enters the filter cylinder (903), after the waste gas is subjected to preliminary filtration of the filter cylinder (903), dust contained in the waste gas is adsorbed on the filter cylinder (903), and further waste gas continuously ascends;

step three: after the waste gas enters the louver ring belt (10), under the speed reducing effect of the louver ring belt (10), coke particles contained in the waste gas are blocked and drop into the air inlet tank (8) at the bottom along the way, and meanwhile, the waste gas continuously enters, flows between the louver She Huandai (10) and the air inlet tank (8) and continuously increases in quantity until the single waste gas discharge is finished, the coke particles are settled into the air inlet tank (8), and the collection is completed by the recovery pipe (802) communicated with the suction equipment;

step four: the waste gas continuously floats upwards, is filled to the top of the spray tank (2) by the air guide cover (902) and the drainage tube (905), and at the moment, the spray tube (203) continuously sprays downwards and enters the water collecting ring (904), harmful substances contained in the waste gas at the top of the spray tank (2) are adsorbed and guided into the water collecting tank (901) by the water collecting ring (904), and then are gathered in the gap between the water collecting tank (901) and the air guide cover (902) and discharged by the water outlet pipe (7);

step five: the purified exhaust gas is subjected to the air suction effect of the top discharge mechanism (5), and the air outlet cylinder (508) pumps the purified exhaust gas into the exhaust pipe to directly finish the discharge in the atmosphere.
