What functions are needed for the airtight hood to meet the production conditions?

In the drying department of the papermaking industry, the value of the airtight air cover is relatively high compared with other drying equipment, because it is a very important supporting equipment in the papermaking equipment. 

For the equipment with high drying skills, the airtight air cover is also a kind of drying equipment that can ensure its quality. 

However, the airtight air cover in the design to meet some conditions in order to make the paper machine work normally.

1. Provide a closed high temperature environment in the paper machine production line to facilitate the drying of the paper, reduce the exhaust air volume, and improve the effect of heat recovery of the air cover exhaust air. 

The most popular design in the world is that the dry bulb temperature in the air cover is 80-85 ℃ and the dew point temperature is 58-62 ℃. 

2. The airtight air cover in the paper machine production line must provide convenience for the monitoring, operation and maintenance of the operation of the paper machine, and must be able to guide the paper and change the roll conveniently. 

3. The high temperature and high humidity in the airtight air cover in the paper machine production line is especially easy to cause condensation. The design of the air cover must completely put an end to the condensation and dripping of the air cover roof.

4. Make sure that the gas in the air cover of the paper machine is not emitted to the workshop as much as possible. 

5. The airtight air cover in the paper machine production line should be able to adjust the longitudinal exhaust air volume of the paper machine to ensure the air exhaust volume required by each dry part of the paper sheet. 

6. The airtight air cover in the paper machine production line should fully consider lighting, fire fighting and other facilities to meet the needs of all aspects. 

7. The airtight air cover in the paper machine production line occupies a large area in the paper machine workshop, so the appearance of the air cover must be beautiful and durable.
