Automation Control Equipment—Paper Plant Automation Control Equipment

Automation Control Equipment is the necessary equipment for many industries. Many manufacturers produce the equipment, but because the automation equipment of paper mill needs high professional technology, it always produced by professional company that specialized in automation technology in paper making industry for many years.

The key automation control equipments that the paper mill should choose are: Distributed Control System of pulping section (DCS); Headbox Control System; Drive Control System of paper machine; Paper Basis Weight and Moisture Quality Control System (QCS); Energy-saving Heating Control System(GCS); Rewinder Control System, etc.

Distributed Control System of pulping section (DCS) is always applied to the pulping system with large capacity or high requirement. According to the technology requirement, it collects dispersedly and computer auto control the technology data during pulping process such as: flow, pressure, consistence and liquid level.

The system set the whole technology process and procedure parameter on computer, which is very convenient for operator to control the entire pulping technology procedure parameter in control room.

The system can guarantee the product quality; reduce the raw material and energy consumption; improve working condition and ensure production safety.

According to the actual situation, the user can control the different procedure parameter selectively, optimize or simplify the system.

The above system is expensive, for the smaller pulping system, it always uses the point to point --direct control system. That is to have energy-saving control of the high energy-consumption point; the single circuit control of key technology parameter.

Through operating desk on site or operating workstation to have the site operation, which can reduce the system cost.

Paper Basis Weight and Moisture Quality Control System (QCS) is applied to the system that measure and corresponding control paper basis weight and moisture on line.

There has a scanning frame before reeling machine. This scanning frame is equipped with a basis weight detection sensor and a moisture detection sensor.

These two sensors can move back and forth on scanning frame, and can detect the paper basis weight and moisture variation dynamically.

In order to control paper basis weight and moisture, PLC controls the technology parameter, such as pulp consistence, flow and dry steam, etc.

GCS is used for energy saving control the steam heating of dryer cylinder. It is using ejector type heat pump technology to have the second steam ejector pressurization for the dry section, emptying the inside water, recycling the waste heat and condensate water furthest, which is 15% energy saving than traditional steam supply. Besides, this system can realize multi stages pressure differential coordinate control, optimize the surface concentration curve and remain the curve unchanged, so it can improve the product quality stably.

Rewinder Electric Control Systemincludes: torque control of unwind roll electromotor; web tension control; speed and torque control of supporting roll; press nip pressure auto control of riding roll; web length measurement and control; finished roll diameter measurement and control, etc.

Rewinder has two drive control ways: AC frequency conversion motor control and DC speed control.

AC control advantages: saving electric energy; longevity service; electromotor maintenance free; but high cost.

The DC control system is low cost but the electromotor brush is needed to renew periodically and the DC commutator is need to maintenance periodically. Besides, DC electromotor has the lower efficiency.
