Collecting, dirt removing and discharging integrated machine barrel degassing system

The utility model discloses a collecting, dirt removing and discharging integrated machine barrel degassing system, and belongs to the technical field of tail gas treatment. The system comprises a settling mechanism, a nitrogen diluting mechanism, a condensing mechanism and an emptying mechanism, the condensing mechanism comprises the combination of two steam jackets and condensers, and the working mode of the combination of zero steam jacket, one steam jacket and two condensers can be achieved through control of different valves. By matching with nitrogen dilution at an inlet in the nitrogen dilution mechanism and further dilution of the gas settled by the settling tank, multiple working modes can be combined, and accurate matching is performed according to the concentration of the VOC gas discharged by the granulating unit, so that the purpose of reducing energy consumption on the premise that the tail gas can meet the emission standard is achieved. 一种收集、除污、排放一体式机筒脱气系统，其属于尾气处理的技术领域。该系统包括沉降机构、氮气稀释机构、冷凝机构和排空机
