Mechanical equipment what are the main parts of the ventilation system of the paper machine?

Do you know what parts of the mechanical equipment paper ventilation system are made up of? 

Today, Shandong Fengxin Science and Technology will introduce in detail that the paper machine industry as a whole is a high-input industry, and China's large-scale paper machines still need to rely on imported equipment. China is now vigorously encouraging domestic enterprises to produce and develop large-scale paper machine equipment, as much as possible to overcome some technical difficulties and make up for the gap in paper machine equipment. 

So what are the major parts of the paper machine equipment?

An airtight chood for the dryer section. 

The closed hood is one of the more familiar parts, and the position of the closed hood is also the first place in the ventilation system of the whole paper machine. As an important part, the performance and function of the closed hood need to be guaranteed. For example, the closed hood, such as providing a closed and high temperature environment, can make the paper dry and reduce the exhaust air volume. 

At present, it is more common in the world that the temperature in the closed hood is kept at 80-85 ℃ and the dew point temperature is kept at 58-62 ℃. 

The important point is that the closed hood needs to completely put an end to condensation dripping, which is necessary to ensure tightness. 

Blower box in closed hood. 

The blower of the closed hood is also a more important part, and its main function is to balance the exhaust in the hood and ensure the high-speed and smooth operation of the paper web. The closed hood produced by Shandong Fengxin Science and Technology Development Co., Ltd. can be equipped with dryers with different functional requirements according to different grades and speed.

Closed hood exhaust heat collector. 

The exhaust temperature of the closed hood is generally recommended to be controlled at about 82 ℃, and its main function is heat recovery. 

Some supporting equipment of paper machine. 

The supporting equipment includes exhaust system, conveying equipment and so on, and the improvement of the supporting equipment can better complete the operation. Today, several major parts of the ventilation equipment of the paper machine are talked about here, and the cooperation and coordinated operation between the various parts of the ventilation equipment of the paper machine can achieve high-efficiency paper drying process. The drying section of the paper machine is also one of the factors that determine the ventilation condition of the papermaking workshop.
