Multifunctional injection device for organic waste gas treatment and treatment process thereof

The invention relates to the technical field of industrial waste gas purification treatment, in particular to a multifunctional injection device for organic waste gas treatment and a treatment process of the multifunctional injection device. Waste gas is sprayed and purified through the arranged purification spraying mechanism, impurities precipitated in the waste gas are filtered and collected in the purification auxiliary mechanism for centralized treatment, and purified waste liquid is discharged from the liquid discharging pipe; according to the waste gas purification device, the corresponding injection purification work can be carried out according to the actual concentration and range of waste gas, on the basis that the purification work efficiency is guaranteed, waste of purification liquid medicine is avoided, the waste gas is stirred through the arranged stirring plate, the contact full degree of the waste gas and the liquid medicine is improved, and the purification work efficiency is improved; the
