Furthermore, the draft tube is connected to the air outlet in a flange mode.
Furthermore, the honeycomb duct is V-shaped.
Further, the steam generator is connected with a water storage tank through a water conveying pipeline, and a water pump is installed on the water conveying pipeline.
The beneficial effects of the utility model reside in that, the utility model discloses a vibration frequency when steam washing centrifugal fan's vibration sensor acquireed the spiral case operation, after vibration frequency surpassed the threshold value scope, the motor stall, and steam generator opens in order to produce high temperature vapor, and actuating cylinder pushes the inserted sheet to the air intake of guide duct in order to close the spiral case for high temperature vapor gathers in the spiral case and washes the oil smoke grease with high temperature, makes the oil smoke grease trickle down along the lateral wall of spiral case inner wall and impeller under the high temperature effect. After high-temperature cleaning for a certain time, the oil cylinder is driven to draw out the insert to open the air inlet of the volute, the steam generator is closed, the motor is started to discharge oil dirt from the air outlet by utilizing the centrifugal force and the wind power of the impeller, so that the centrifugal fan utilizes steam to efficiently clean the impeller and the interior of the volute, and the normal operation of the impeller is kept.
