Sound Reducing Closed Paper Machine Hood Ventilation System Moisture Removal

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.
