Sound Reducing Closed Hood And Ventilation System Moisture Removal
During the operation of the dryer, a large amount of hot and humid
air will be produced. The application of the closed hood and
ventilation system is to seal the paper dryer completely. It is
necessary to ensure that the paper dryer can meet the operating
requirements of high temperature and high dew point and meet the
operating requirements of the paper machine, but also ensure the
heat retention, air tightness, sound reduction and good appearance
of the closed hood.
Material
Aluminium alloy, stainless steel, carbon steel
Product features
The closed hood is composed of framework, top wall panel, internal
channel and various doors. The interior is equipped with lighting,
fire protection and other systems, which can effectively improve
the ventilation conditions of the paper machine and optimize the
working environment of the workshop;
The tubular heat recovery device matched with the closed hood has
stable heat transfer coefficient, long service life and is easy to
clean. It can recover the exhaust heat and preheat the fresh air to
the maximum extent, achieving the effect of energy conservation and
environmental protection;
All kinds of ventilators matched with the closed hood can not only
improve the evaporation rate of the paper web moisture, but also
improve the stability of the paper web operation;
The hood control system can realize automatic control according to
the change of ventilation parameters in the hood to ensure that the
paper machine ventilation is in the best operating condition.
Application
It is mainly applicable to the dryer of long-web multi-cylinder
paper machine in the paper industry
Working principle
After the paper machine dryer adopts a fully enclosed hood and a
complete ventilation system, it can not only achieve various
functions such as moisture removal and air supply, but also meet
the ventilation requirements of different seasons and different
output. At the same time, the ventilation system is equipped with
various automatic control functions to ensure that the paper
machine is in the best operating condition and minimize the energy
consumption in the paper making process.
