Weathering Steel Yankee Hood And Ventilation System For Special Paper Machine
Yankee hood and ventilation system are specially designed for high-speed toilet paper machine or special paper machine. The air supply working temperature of the hood can be adjusted, and its actual air supply temperature and air volume must be adjusted according to the operating parameters of the paper machine. All water vapor evaporated from the Yankee cylinder is taken away by the exhaust device, and the exhaust air is discharged into the atmosphere after heat recovery and countercurrent heat exchange with fresh air, and then cooled by secondary air and water heat recovery.
Material
Stainless steel, carbon steel, weathering steel
Product features
Maximum working speed: 2200m/min;
Heat medium type: steam type, electric auxiliary heat type, fuel air type;
According to the different heat source of Yankee hood ventilation system, the maximum air temperature can be up to 500 DEG C, the airflow speed can reach 160m/s.
Functions
The application of Yankee hood and ventilation system can greatly improve the drying rate of large cylinder, greatly increase the output of paper machine and reduce the energy consumption per ton of paper.
Working principle
Using contact drying and convection drying principle, the high temperature and high speed hot air vertically blowing to the paper, making fast convection heat transfer with paper surface, air film on the interface is damaged or reduced the thickness, so that the large cylinder drying rate increases greatly, and greatly improve the machine output and reduce the energy consumption of tons of paper.
