Vertical Roots blower is a type of positive displacement fan, which belongs to a special structural form of Roots blower. Due to its design characteristics, it has a wide range of applications in the industrial field. The following is a detailed introduction to its characteristics, working principle, and application fields:
1、 Structural characteristics
1. Vertical design:
Unlike traditional horizontal Roots blowers, vertical Roots blowers directly mount the motor on the blower base, with inlet and outlet mufflers installed on both sides of the base. This design allows the fan to occupy less ground space, making it suitable for environments with limited space.
2. Oil free lubrication:
The rotor does not come into direct contact with the casing or between rotors, and does not require lubricating oil. The transported gas is free of oil pollution, making it suitable for applications that require high gas purity.
3. Sealing:
A high-precision sealing structure is adopted between the rotor and the casing, effectively reducing gas leakage and improving work efficiency.
4. Low noise:
By optimizing the rotor profile and airflow channel design, airflow pulsation and vibration are reduced, resulting in low operating noise.
2、 Working principle
The upright Roots blower uses two identical three bladed rotors inside to mesh with each other and rotate in the opposite direction at a constant speed inside the cylinder. When the rotor rotates, gas is drawn in from the intake port, compressed by the squeezing effect of the rotor, and finally discharged from the exhaust port. Its working principle is based on volumetric compression, where gas is forcibly transported within a closed chamber formed between the rotor and the casing. The flow rate is proportional to the rotational speed, and the pressure can be adjusted within a range.
3、 Technical advantages
1. Forced air supply:
Even with pressure changes, the fan can still maintain stable flow output, suitable for process scenarios that require stable air volume.
2. Strong adaptability:
Capable of transporting various gases, including explosion-proof, corrosive, and high-temperature gases.
3. Easy maintenance:
Compact structure, easy maintenance, suitable for long-term continuous operation.
4. Energy conservation and environmental protection:
Oil free operation avoids oil mist pollution and meets environmental requirements.
4、 Application Fields
1. Industrial production:
As a combustion supporting fan in cement production, it sends combustion gas from the bottom of the kiln to help materials fall vertically inside the kiln, achieving the firing of clinker.
2. Wastewater treatment:
Used for aeration in sewage treatment, increasing the oxygen content in water, and accelerating the decomposition and degradation of wastewater.
3. Aquaculture:
In large-scale fish and shrimp farms, increasing oxygen levels in water through oxygenation promotes the growth of aquatic organisms.
4. Chemical industry:
Used for transporting chemical raw materials, reaction gases, explosive gas mixing, wastewater treatment, ventilation and exhaust, gas pressurization, pulse dust removal, etc.
5. Mining and dust treatment:
Strengthen underground ventilation in the mine exhaust system, float dust in the dust treatment workshop, and improve the working environment.
5、 Development Trends
With the improvement of environmental awareness and the continuous advancement of technology, upright Roots blowers, as environmentally friendly fans, will be more widely used in the following areas:
1. Energy conservation and emission reduction:
Reduce energy consumption and improve energy efficiency through technological innovation.
2. Intelligent control:
Combining IoT and automation technology to achieve remote monitoring and intelligent regulation.
3. Innovation in materials and manufacturing processes:
Adopting new materials and advanced manufacturing processes to improve product quality and performance.
