What are the advantages of closed hood?

Closed hood refers to the closed hood of the paper machine, which is used to recycle the steam generated by the paper machine for better drying and energy saving. It can be seen that the closed hood plays an important role in papermaking equipment. Although a layman doesn't know much about this equipment, he should also know the purpose of this equipment through the introduction of the above sentence. Shandong Fengxin technology has developed the high temperature and high humidity advantage closed hood for drying cadres. As a professional R & D enterprise, relevant technicians have sorted out some advantages of closed hood for us.

Advantage 1: Z eliminates thermal bridge to a large extent

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

Advantage 2: completely eliminate dripping at the top

In order to adjust the longitudinal exhaust air volume in the hood and eliminate dripping and dripping at the top of the hood, we set up air collecting duct 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 air collecting duct can be called a movable roof, which can provide an operating environment consistent with the exhaust temperature for the top of the hood and completely eliminate dripping at the top.

Advantage 3: humanized operation and maintenance design

A full-length electric lifting door is set at the operation side, and a full-length heat-insulating glass window is set on the door; The transmission measurement is equipped with a sliding door, and the door is also equipped with a heat-insulating glass window, so that the operation condition of the paper machine can be seen at a glance. The lifting door is equipped with a paper breaking signal interlocking device, but once the paper breaking lifting door can be lifted automatically; Of course, the lifting of the lifting door can also be manually operated on the console. A manual door for changing the roller is opened on the side plate of the operation, and a longitudinal and transverse manual hoist is set in the air 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 liftgate body.

Advantage 4: perfect air tightness

When the liftgate is opened, in order to prevent the hot and wet gas in the hood from overflowing and prevent the cold air in the workshop from entering the hood, we set a "zero" control device on the hood. The "zero position" is adjusted by controlling the amount of hot air sent to the hood through the "zero position" detection device installed on the hood, which can effectively save energy and reduce consumption.

Advantage 5: lighting and automatic fire extinguishing system

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

Advantage 6: beautiful appearance, enhance the corporate image

The air hood panel adopts sinusoidal corrugated plate, with exquisite and rigorous appearance and generous visual effect in the workshop, which greatly improves the corporate image.

After reading the above advantages, I believe you will know more about this equipment. These advantages make it a "good friend" of papermaking equipment and provide great convenience for people. Fengxin technology can not only provide closed gas hood, but also sell Yankee gas hood. Friends in need can visit and communicate with the company, or call: + 86-159-6575-9999!
