Analysis of application technology of rotary fan in integrated sewage treatment equipment
Rotary fans have a wide range of applications in integrated sewage treatment equipment. The following is a detailed introduction to their applications:
1、 The function of rotary fan in integrated sewage treatment
1. Provide oxygen:
The main function of a rotary fan is to blow a large amount of air into an aeration tank or tower, providing sufficient oxygen for microorganisms. This is one of the core processes in wastewater treatment, as sufficient oxygen helps microorganisms degrade substances and other pollutants in wastewater.
2. Maintain mixed state:
By continuously stirring and stirring the water body, the rotary fan can deposit sludge and gather bubbles, maintain uniform distribution of microorganisms in the wastewater, and thus improve the treatment efficiency.
3. Aeration effect:
In the aeration tank, the bubbles formed by the rotary fan can fully contact the substances in the sewage, improve the efficiency of oxygen transfer, and further promote the degradation activity of microorganisms.
2、 Working principle of rotary fan
The working principle of a rotary fan is an automatic oil supply device formed by the pressure difference generated in the working chamber. Its working process includes suction stroke, compression stroke, and exhaust stroke. The eccentric operation of the rotor inside the fan causes a change in the volume between the blades in the rotor slot, which sucks in, compresses, and exhales air. This variable capacity compression method enables the rotary fan to have stable airflow output and pressure performance.
3、 Advantages of Rotary Fans
1. Low noise:
The design of the rotary fan emphasizes low noise performance and adopts a series of noise reduction measures to significantly reduce the noise level during equipment operation.
2. Small size:
The rotary fan has a compact size and does not require a large amount of space for installation, saving space.
3. High energy efficiency:
Rotary fans have a high energy efficiency ratio, which can reduce energy consumption while ensuring gas output, in line with the development trend of energy conservation.
4. Stable operation:
The rotary fan has a sophisticated structure, stable and reliable operation, and can meet the high requirements for gas source stability in the sewage treatment process.
5. Easy maintenance:
Rotary fans are easy to maintain, have few malfunctions, and have a long lifespan. Its low-speed design reduces wear and extends service life.
4、 Selection suggestions for rotary fans
When selecting a rotary fan, calculations should be made based on the actual needs of the integrated sewage treatment equipment, taking into account performance indicators such as fan airflow, pressure, noise level, and material corrosion resistance. Choosing too large a size may lead to energy waste and increased operating costs, while choosing too small a size may not meet the processing requirements and affect the processing effect. At the same time, suppliers with good after-sales service should be selected to ensure the quality and reliability of the fan, and to receive timely and effective technical support and maintenance services during use.
In summary, rotary fans have broad application prospects and significant treatment effects in integrated sewage treatment equipment. Its advantages of low noise, small size, high energy efficiency, stable operation, and simple maintenance make it one of the important equipment in the sewage treatment process.
