What are the characteristics and installation methods of the Yankee hood?

In order to give everyone a certain understanding of the Yankee hood, the following summary has been made on its structural characteristics and installation method.

Structural characteristics of Yankee hood equipment

The Yankee hood consists of a high-temperature high-speed impact hood and an external thermal cycling system.

1. The hood frame is welded with carbon structural steel, which has excellent mechanical strength function. Both the inner and outer panels are made of stainless steel or galvanized steel plates with strong resistance to high temperature and corrosion (depending on the customer's paper machine), and centrifugal glass fiber insulation cotton is filled between the inner and outer panels to ensure that the cover has good insulation function to avoid heat loss.

2. The nozzle and air duct are made of stainless steel plate material, specially planned and meticulously processed to ensure that the nozzle can operate under high temperature conditions without deformation throughout the year, ensuring uniform blowing.

3. The combination of left and right half hoods is selected for the air hood, making the equipment simple and easy to protect.

4. Utilize fluid accounting software to calculate and simulate, scientifically plan and layout the circulating air duct outside the hood, scientifically select and match air 4. Fully optimize the flow field distribution of the system, select advanced heat recovery equipment, achieve uniform air supply and save system energy consumption.

Installation method of Yankee hood

1. Before lifting the equipment, check whether the relevant lifting equipment and equipment are sturdy and secure to avoid equipment damage due to lifting.

2. Pay attention to adjusting the height and position of the frame of the hood equipment to ensure that the distance between the arc surface of the hood nozzle and the cylinder barrel meets the technical requirements and is equal throughout the ground.

3. Necessary equipment such as the support frames (seats) of the hood should be sturdy, and the sliding equipment should rotate flexibly without jamming or interference.

4. The air duct is tightly and firmly connected, reinforced and supported, and insulated.

5. The fan is required to be constructed according to the technical requirements of the relevant equipment of the fan.
