定义
A ventilation hood is a critical component in the dryer section of a paper machine, designed to efficiently remove evaporated moisture, control humidity, and maintain optimal drying conditions. It consists of a hood enclosure, exhaust ducts, air supply systems, and control mechanisms to ensure uniform drying and energy efficiency.
工作原理
The ventilation hood operates by creating controlled airflow over the paper web as it passes through heated dryer cylinders. It extracts moisture-laden air through exhaust systems while supplying conditioned air to maintain temperature and humidity balance, utilizing principles of heat transfer, fluid dynamics, and mass transfer.
材料
Typically constructed from corrosion-resistant materials: stainless steel (AISI 304/316)aluminum alloysor coated carbon steel. Insulation materials include mineral wool or fiberglass. Gaskets and seals are made from high-temperature silicone or EPDM rubber.
Noise Level
<85 dB(A)
Pressure Drop
100-500 Pa
Airflow Capacity
10,000-50,000 m³/h
Humidity Control
±5% RH
Temperature Range
50-150°C
标准
ISO 12100ISO 13849DIN 24163DIN EN 1505
