Closed hood, generally speaking, is the closed hood of paper machine. It is a closed bungalow type cover of aluminum alloy material used for drying cadres and sizing section of paper machine. Its function is to recycle the steam generated by paper machine for better drying and energy saving.

Shandong airtight hood

Advantage 1: eliminate heat bridge to a large extent

The closed hood is a modular closed structure. In order to ensure that the high temperature and humidity air (dry bulb temperature 80-85 ℃, dew point temperature 58-62 ℃) in the hood does not condense and drip, the top plate, end plate and side plate of the hood are sandwich structure, the inner plate and outer plate are rust proof aluminum plate, and the middle is hard centrifugal glass wool plate. Tongue and groove connection is adopted between plates to eliminate "hot bridge" to a large extent.

Advantage 2: completely eliminate top dripping

In order to adjust the longitudinal exhaust air volume in the hood and prevent dripping and dripping at the top of the hood, we have a header at the top of the hood and adjustable doors on both sides to adjust the exhaust air volume in different areas. At the same time, the header can be called a movable roof, which can provide a running environment consistent with the exhaust temperature at the top of the hood and completely eliminate dripping at the top.

Advantage 3: humanized operation and maintenance design

The tending side is equipped with a full-length electric lifting door, which is equipped with a full-length insulated glass window; the back side is equipped with a sliding door, and the door is also equipped with an insulated glass window, so the operation status of the paper machine is clear at a glance. The lifting door is provided with a interlock device with the paper break signal, once the paper break lifting door can be automatically lifted; of course, the lifting of the lifting door can also be manually operated on the console. A manual door for replacing the roller is opened on the tending side panel, and a vertical and horizontal manual hoist is arranged in the hood, which can easily lead paper and change the roller. At the same time, the rope breaking protection device ensures the safety of personnel and the lifting door body.


Jinan airtight hood

Advantage 4: good air sealness

When the lifting door opened, in order to prevent the hot and wet air in the hood from overflowing, and also to prevent the cold air in the workshop from entering the hood, we have set the "zero position" control device on the hood. The "zero position" is adjusted by the "zero position" detection device installed on the hood to control the amount of hot air sent to the hood, effectively saving energy and reducing consumption.

Advantage 5: lighting and automatic fire extinguishing system

The low pressure lighting system and automatic fire extinguishing system in the closed hood fully meet the requirements of fire fighting and lighting.

Advantage 6: beautiful appearance, enhance the corporate image

The air mask panel adopts sine wave pattern plate, with exquisite and rigorous appearance and comfortable visual effect in the workshop, which greatly improves the corporate image.


Airtight hood

The modern paper closed hood increases the functions of air supply and paper stabilization, which can balance the moisture, stabilize the paper and better dry the paper. Therefore, the closed hood has become an indispensable part of the papermaking equipment.
