The utility model belongs to the technical field of waste gas purification, and in particular relates to a semi-closed tunnel waste gas treatment system, which comprises a waste gas collection line, the waste gas collection line is connected with a primary filter, and an air outlet of the primary filter is connected with an electrostatic precipitator. The air outlet of the electrostatic precipitator is connected with the low temperature plasma waste gas treatment equipment, the air outlet of the low temperature plasma waste gas treatment equipment is connected with the deodorization catalytic oxidation bed, and the air outlet of the deodorization catalytic oxidation bed is connected with the exhaust pipe through the fan. The utility model adopts the combined process of primary effect filtration, electric dust removal and plasma, which can achieve the purpose of high-efficiency dust removal, oil removal and deodorization; At the same time, it also solves the problem of odor pollution, avoids the pollution of exhaust gas to the environment and the impact of human health, and is environmentally friendly and energy-saving. |
