Pulp Drying Machine and Drying System

Description
Zhengda Qingke Hi-tech Machinery Co., Ltd. is capable of providing customers worldwide with turn-key project services of pulp drying machine and drying system. These services include consultation, designing, management, installation and commissioning.

Advantages of Pulp Drying Machine and Drying System
1. The length of drying section can be shortened by more than 50%, which greatly saves constuction costs.
2. Pulp drying machine can easily regulate horizontal moisture difference to obtain pulp boards of more homogeneous moisture.
3. Pulp boards are affected by less tensile force in the drying section so that they can move more smoothly, resulting in less broken paper.

Components of Pulp Drying Machine and Drying System
1.Twin Wire Forming Section
This part is made up of hydraulic headbox, closed dehydration system, dehydration tank, wire stretcher, wire rectifier and cleaning device.
2. Press Section
Press section includes a set of vacuum preloading, a set of vacuum pressing and a set of high impulse pressing. This pressing structure can ensure that pulp boards get effective dehydration in this section.

3. Dryer Section
The dryer adopts multi-layer arrangement and bases on airflotation non-contact drying principle to dry pulp boards. Paper web moves through jet cases which provide hot air as energy and heat to dry paper web. The upper and lower jet cases can be separated by air cylinder for cleaning and threading.

Hot Air Circulation Process
1. To make most use of heat, the outer circulation system of dryer has two-stage heat recovery devices. The first one is gas-gas heat recovery device which employs hot and humid air to preheat fresh air. The fresh air then is heated in the heater and later sent to the bottom of dryer.
2. The second stage is gas-water heat recovery unit. It makes use of waste heat to warm up process water and heating water.
3. The bottom of dryer is equipped with a set of air supply system that functions to cool dowm pulp boards before they leave the dryer section.

Corollary Equipment and System
1. Twin wire hot air drying pulp machine
2. Steam condensate system
3. Pulp approach flow and purification system
4. Vacuum system
5. Broken paper disposal system
6. Transmission control system
7. DCS and QCS paper machine control system
