Oxidation fan: principle, application and selection guide
Oxidation fan is a specialized power equipment used to provide oxygen required for oxidation reactions, which plays an important role in environmental protection, chemical industry, metallurgy and other fields. Its core function is to deliver a stable flow of air or oxygen to the reaction system through forced ventilation, ensuring the full progress of the oxidation reaction.
Working principle and equipment characteristics
The oxidation fan adopts a volumetric working principle, which achieves gas transportation by rotating the rotor inside the casing to form a change in sealed volume. When the equipment is running, two interlocked rotors rotate in reverse inside the casing, creating negative pressure at the inlet to suck in gas and positive pressure at the outlet to discharge gas, thus achieving continuous gas supply.
This type of equipment has several significant characteristics: firstly, the output air volume is stable and not affected by changes in system back pressure; Secondly, oil-free design can be adopted to ensure the purity of the transported gas; In addition, the device has a compact structure, reliable operation, and easy maintenance; It can provide high outlet pressure to meet the requirements of deep aeration and other processes.
Main application areas
Oxidation fans play a key role in multiple industrial fields:
1. In the field of sewage treatment: In the activated sludge process, sufficient oxygen is provided to the aeration tank to promote the decomposition of organic matter by microorganisms.
2. Flue gas desulfurization system: In the wet desulfurization process, air is provided to the oxidation tower to oxidize sulfite into sulfate.
3. Chemical production process: Provide oxygen or air required for the process in various oxidation reactions.
4. Aquaculture industry: Provide oxygenation for high-density aquaculture water bodies and improve the aquaculture environment.
Key points for equipment selection
Choosing a suitable oxidation fan requires consideration of multiple technical parameters:
-* * Airflow requirement * *: Calculate the required gas supply based on the treated water volume, water quality characteristics, and oxidation requirements
-* * Pressure parameters * *: Consider factors such as water level depth, pipeline resistance, and pressure loss of aeration devices
-* * Medium Characteristics * *: Clarify the composition, temperature, and corrosiveness of the conveying medium
-* * Installation environment * *: Consider factors such as environmental temperature, altitude, etc
-* * Energy Efficiency Standards * *: Choose equipment that meets energy efficiency requirements to reduce operating costs
Usage and maintenance suggestions
To ensure the long-term stable operation of the oxidation fan, the following precautions should be taken:
Regularly check the operating status of equipment, monitor changes in parameters such as vibration and noise; Replace lubricating oil and filters on time to maintain good lubrication of the equipment; Clean the cooling system to ensure effective heat dissipation; Regularly inspect the seals to prevent gas leakage; Establish equipment operation records and document maintenance and upkeep.
development trend
With the improvement of environmental protection requirements and the advancement of energy-saving technologies, oxidation fans are developing towards energy-saving, low-noise, intelligent and other directions. The new type of oxidation fan commonly adopts blade design, precision manufacturing technology, and intelligent control system, which not only improves equipment efficiency but also greatly reduces operation and maintenance costs.
In short, as an important equipment in industrial production, the selection and use of oxidation fans require professional technical support. Users should choose suitable equipment models based on actual process requirements and establish a comprehensive maintenance system to ensure long-term stable operation of the equipment. Through reasonable equipment selection and standardized operation and maintenance, the working efficiency of the oxidation fan can be fully utilized, providing reliable guarantee for the production process.
