Abstract
The invention provides a fan device driving gas to circulate in a high-temperature high-pressure sealed pipeline. A Root's or centrifugal fan and a motor are disposed in a fan hood. Two ends of the fan hood are connected with front and rear end covers of the fan through flanges. The fan hood is cylindrical. The front and rear end covers of the fan hood are pan-shaped. The front end cover of the fan hood is welded to an intake pipeline. The rear end cover of the fan hood is welded to a straight tube. The outer end of the straight tube is welded to an exhaust pipeline. The inner end of the straight tube is welded to a corrugated tube. The other connecting end of the corrugated tube is provided with two seal grooves, and O-shaped seal rings are disposed on the seal grooves. After the O-shaped seal rings are sleeved on the connecting end of the corrugated tube, the corrugated tube is inserted into an outlet of the fan directly. A lead flange is arranged at the upper end of the fan hood. Two water access tube joints are welded on two sides of the fan hood.
