DG型旋风除尘器是在毛主席革命路线指引下,科研、设计单位与工厂三结合的一项科研成果。自1973年末开始,在现场试验与模型试验同时进行的情况下,着重对提高效率,降低阻力以及锅炉的负荷适应性等方面进行了研究。通过一年模型试验和现场试用,确定第六方案为最佳方案定型。1975年初在华东第二次工业锅炉除尘专业会议上征 The DG cyclone dust collector is a scientific research achievement combined with scientific research, design institutes and factories under the guidance of Chairman Mao’s revolutionary route. Since the end of 1973, under the circumstances that field tests and model tests were carried out at the same time, emphasis was placed on improving efficiency, reducing drag, and boiler load adaptability. Through one-year model tests and field trials, the sixth plan was determined as the best plan. At the beginning of 1975, the second industrial boiler dust removal professional conference in East China was registered.
