Vacuums in Pulp & Paper for Filtration and Dewatering
Hibon offers environmentally conscious vacuum solutions for filtration and dewatering processes in the Pulp & Paper industry.
Vacuum pumps are commonly used in the pulp and paper industry for filtration and dewatering processes. These pumps create a vacuum to draw out water or other fluids from the pulp or paper. This allows for the separation of solid materials from liquids using a dewatering filter. These pumps play a critical role in the filtration and dewatering processes used in the pulp and paper industry.
By removing excess water and other fluids, vacuum pumps help to create a higher quality and more uniform product. They can also improve the efficiency of the production process.
Filtration & Dewatering Systems
In the pulp and paper industry, filtration is an essential process that separates sediment and other particles from the pulp slurry or wastewater. By removing solid particles, filtration helps to improve the quality of the pulp and paper product. It also minimizes waste in the manufacturing process. There are several different filtration methods available.
Vacuum filtration is a process that uses vacuum pumps to create a pressure differential across a filter medium. This causes the sediment laden water to flow through the filter and leaves the solid particles behind. Vacuum filtration is commonly used in the wire, press, and drying sections of paper machines.
Dewatering is a process of removing water or other fluids from a solid material, such as pulp or paper. This can improve the quality and reduce its moisture content. Dewatering is an essential process that is used to remove excess water from the pulp slurry and paper sheets.
Vacuum dewatering is a process that uses pumps to create a pressure differential across a filter medium or porous roller. This draws out the excess water from the pulp slurry or paper sheet. Dewatering can improve the quality of the pulp and paper product while minimizing waste in the manufacturing process.
Benefits of Addressing Energy Costs
Paper mills can benefit in many ways by saving electricity and water costs, as well as by reducing their carbon footprint. Here are some of the key benefits:
● Cost effective: Electricity and water are two of the biggest expenses for paper mills. By implementing energy efficient technologies and processes, paper mills can reduce their consumption of electricity and water. This can translate into significant cost savings over time. Paper mills can improve their bottom line by using more efficient equipment, optimizing water usage, and reducing waste.
● Environmental benefits: Electricity generation and water treatment are significant sources of greenhouse gas emissions and environmental pollution. By reducing their consumption of electricity and water, paper mills can help to reduce their carbon footprint and environmental impact. Paper mills can further reduce their carbon emissions by using renewable energy sources to help mitigate climate change.
● Improved reputation: Consumers and stakeholders are increasingly concerned about the environmental impact of the products and companies they support. Paper mills can adopt sustainable practices to improve their reputations and attract customers who value environmental responsibility.
● Regulatory compliance: Many countries have strict regulations governing energy and water usage, as well as greenhouse gas emissions. Paper mills can ensure compliance with regulations by reducing their resource consumption and adopting more sustainable practices.
Overall, there are many benefits to paper mills in saving electricity and water costs and reducing their carbon footprint. By implementing energy efficient technologies and processes, paper mills can:
● Improve their bottom line
● Reduce their environmental impact
● Enhance their reputation
● Ease regulatory compliance
Hibon’s Pulp & Paper Solution
The Roots-Hibon blower lobe pump is also known as a positive displacement blower. It works by using two counter rotating lobed rotors to trap and transport air or gas through the pump chamber. The operation of the Roots-Hibon blower lobe pump can be broken down into four stages:
- Intake: As the rotors turn, a partial vacuum is created in the intake side of the pump. This draws in air or gas through the inlet port.
- Compression: As the rotors continue to rotate, the lobes trap the air or gas and carry it around the pump chamber. The volume of the chamber decreases as the lobes mesh, which compresses the air or gas.
- Discharge: As it reaches the outlet side of the pump, the compressed air or gas is forced through the outlet port.
- Exhaust: As the lobes continue to rotate, the compressed air or gas is exhausted from the pump chamber.
The Roots-Hibon design ensures no contact between the rotors and the pump casing. This minimizes wear and reduces maintenance requirements. Additionally, precision machined rotors and tight clearances with the casing helps to improve efficiency and reduce leakage.
Benefits and Advantages
● Efficient vacuum creation: In papermaking, vacuum pumps are commonly used for dewatering, filtration, and other processes. It can create a high volume of vacuum at relatively low pressures. This makes it an efficient choice for these applications.
- Reliable operation: It is designed with few moving parts that operate at a relatively low speed. This makes it a reliable choice for papermaking applications, where downtime and maintenance can be costly.
● Low maintenance requirements: The simple design and few moving parts reduces the likelihood of breakdowns and minimizes maintenance requirements. Additionally, the pump is designed with tight clearances to reduce leakage, which can help to prolong the life of the pump.
● Versatile: It can handle a wide range of gases and airflows. This makes it a versatile choice for papermaking applications that require different vacuum levels or flow rates.
The Roots-Hibon pump can offer papermaking operations an efficient, reliable, and low maintenance solution for vacuum and air handling needs. This can help to reduce costs, increase productivity, and improve the overall quality of the final paper product.
