Raw materials have long been a limiting factor in the advancement of the paper mill industry. However, with the increased focus on environmental protection and the conservation of forest resources, the use of wood pulp in raw materials has been decreasing. To maintain production, papermaking enterprises have thus begun to rely on recycled waste paper pulp as a primary source of pulp.
Modern paper industries are intensive in their use of capital, technology, and energy and have a high production output. This production process is complex, with long-term continuity, and is often associated with high energy consumption, heavy processing of raw materials, and an enormous environmental impact. Therefore, significant investments are often necessary for the successful operation of these industries.
Measurements of Paper Mill Flow
Paper mills rely on accurate flow measurement and control to optimize production and maintain quality. With precise flow monitoring, mills can reduce costs and improve efficiency, making it a critical part of any paper production process.
The primary process of modern papermaking is a combination of pulping and papermaking. Pulping uses chemical, mechanical, or various methods to break down raw plant fiber materials into natural color pulp (unbleached pulp) or bleached pulp. Papermaking then combines these pulp fibers suspended in water to create paper sheets that meet specific requirements. Throughout the entire papermaking process, electromagnetic flow meters are used in all sections to measure and monitor the process.
To achieve accurate and reliable pulp flow measurement in a paper machine, the electromagnetic flow meter can be combined with a concentration meter to provide quantitative control of paper production. The electromagnetic flow meter measures the pulp in the pulp blending system, allowing for continuous or intermittent custody of the pulp blending ratio. This ensures accuracy and consistent quality control of the paper produced.
With the advent of modern technology, most papermaking enterprises have replaced their traditional differential pressure flow meters with more advanced electromagnetic flow meters. As a result, these electromagnetic flow meters have become the industry standard in liquid metering for the paper industry, providing unparalleled accuracy and reliability. In addition, their ability to precisely measure even meager flow rates makes them an ideal choice for various papermaking applications.
The electromagnetic flow meter is an ideal choice for measuring fluid flow due to its immunity to changes in fluid density, temperature, pressure, viscosity, Reynolds number, and conductivity within a specific range. In addition, it boasts an extensive measurement range. It can accurately measure turbulent and laminar flow states, outperforming traditional differential pressure flow meters, turbine flow meters, vortex flow meters, and other flow meters.
The electromagnetic flow meter is an ideal solution for fiber suspension, providing effective noise suppression and improved flow measurement accuracy. By utilizing advanced signal processing techniques, the electromagnetic flow meter can significantly reduce the impact of noise on the accuracy of the flow measurement, ensuring accurate and reliable results. Moreover, it can be calibrated easily, making it an ideal solution for fiber suspension applications.
Thanks to its simple structure, the electromagnetic flow meter has no moving, disturbing, or throttling parts that would impede the flow of the measured medium. This means there is no risk of pipe blockage and wear and almost no pressure loss, making it ideal for factories as it consumes only 10~20W of electric power while helping to control environmental pollutants’ discharge strictly.
Electromagnetic Flow Meter Application in Paper Mill Wastewater
Wastewater pollution in paper mills today is a severe problem. Every production stage requires water from raw materials to finished products, making it challenging to avoid wastewater accumulation.
The process requires biological oxidation, flocculation, sedimentation, and other functions to achieve effective sewage treatment. To ensure the process runs smoothly, accurate measurements must be made at each stage, where electromagnetic flow meters come in handy.
For effective sewage treatment, configuring suitable detection instruments is essential for creating a reliable control system. In paper mills, wastewater can be recycled after being purified and treated, thus reducing water and electricity consumption.
To ensure the effective treatment of wastewater, careful measurement and control of discharge water, additives, sludge, and flow rate is critical. Due to the presence of impurities and significant flow changes, as well as its specific conductivity, PTFE lining and 316L electrodes are recommended for monitoring and controlling the process. In addition, these materials are wear-resistant and corrosion-resistant, making them ideal for wastewater treatment.
Flow meters have become vital for paper mills to reduce costs, optimize the slurry ratio, and minimize environmental pollution. By controlling sewage discharge, paper mills can save money and be more efficient while reducing their environmental impact. As a result, this cost-effective and eco-friendly solution is quickly becoming the preferred choice for paper mills worldwide.
In addition to correct installation and grounding, the electromagnetic flow meter must be adequately maintained to ensure reliable flow measurement. With continuous technological innovation and feedback from field use, electromagnetic flow meters are projected to be the leading choice in the flow meter market over the next few years due to their unique advantages.
