Product Content Description:

The paper machine gas cover is an important part of paper drying, and its design has important influence on the normal stable operation and drying energy consumption of the paper machine. The main function of paper dryer is to increase the strength of paper while evaporating and removing moisture from the wet pages. The energy consumption of the drying part accounts for 60% of the papermaking process, the structure design of the air cover system, the ventilation volume and the air condition parameters (temperature and humidity) have great influence on the energy consumption of the drying department.

Paper machine respirator:

The large Angle of the oven is large, the paper is heated area, and the efficiency of the dryer is increased, and the output is increased.

If you enter into the vents and double out, or more or more, it will be suitable for high speed and wide paper machines;

The machine can be equipped with a pneumatic cylinder, which can easily handle the phenomenon of slip paper and clean the orifice plate.

The hot wind impact velocity is greater than 20 m/s, which greatly improves the heat transfer rate of the paper width of the dryer.

The size of the packet Angle is large, the paper width increases, and the efficiency of the dryer is greatly improved.

Exhaust hot air 90% can be recycled (steam reheating), 10% of the exhaust hood. And it's supplemented by fresh air.

Unit evaporation rate: 12 ~ 70kg/m2. H. According to paper machine, paper type is determined by wind speed and opening rate.

According to the form of paper and output, the form can be divided into the porous type, the slit type and the long slit

Paper sealing gas cover:

Sealed air containing electric doors, sliding doors, roller mechanism change, automatic zero control and fire extinguishing system is standard, fully embodies the science and technology, human, maximum energy-saving advantages.


Airtight cover is the highest value in the paper ventilation system. It is a very important equipment in papermaking equipment.

Airtight hood:

Airtight gas cover generally refers to the airtight gas cover of the paper machine, used for the drying of the cadre and the glue department of a closed cover, the function is better energy saving and thermal utilization.

Generally refers to the airtight gas cover of the paper machine, used for drying cadres and the glue department of a closed cover, the function is better energy saving and thermal utilization.

The exhaust air for higher temperature (an average of up to 85 ℃) and to improve the drying efficiency and waste heat recovery

Higher exhaust humidity (up to 160g. H2O/kg. A) to reduce the exhaust volume to reduce the energy saving (send, exhaust fan power less)

The air flow organization is perfect for the steady and efficient work of the paper machine

Advantage 1: to minimize the cold bridge

Advantage 2: completely eliminate the top dripping

Advantage 3: human operation, maintenance design

Advantage 4: perfect airtight effect

Advantage 5: lighting and automatic fire extinguishing system
