3、 Application scenarios
Wastewater treatment: used in aeration tanks to provide sufficient oxygen for microorganisms, help decompose organic matter in wastewater, and purify water quality.
Aquaculture: By injecting air into the water through an aeration system, the dissolved oxygen content in the water is increased, providing a good living environment for aquatic organisms, promoting growth, and increasing aquaculture density and yield.
Material transportation: Used in industries such as chemical and building materials to transport powdered cement, flour, or granular plastics, grains, etc. Mixing materials with air through pipelines, utilizing the generated airflow pressure to transport materials to designated locations, achieving continuous and stable transportation.
Industrial combustion assistance: In cement production, as a combustion assistance fan, combustion gas is sent from the bottom of the kiln to help materials fall vertically inside the kiln, achieving the firing of clinker.
Homogenization warehouse mixing: The discharged compressed gas enters the material layer through the bottom inflation box of the warehouse, causing the material to fluidized and roll up and down, achieving a uniform mixing effect.
Fuel atomization: Used in tunnel ceramic kilns, vertical magnesia kilns, and glass pool furnaces to atomize fuel, dividing the oil flow into fine strands and trapping bubbles, forming a group of small diameter droplet mist.
Pneumatic ash conveying: In thermal power plants, ash is sent into the ash silo through compressed gas, or a vacuum pump is installed at the end of the ash discharge system to suck the gas in the pipeline and make it fall into the ash silo.
Promoting chemical changes: In the gas-solid two-phase contact of chemical changes, the compressed gas provided causes solid particles to float and fluidized, fully contacting with other products or catalysts, thereby improving the speed and efficiency of the reaction.
Vacuum cleaning: Use a hose suction head to clean the dust on the pot body and platform, and use a vacuum pump to extract the gas from the dust and clean various loose particles and dust.
Incinerator air supply: In the incinerator, fuel is sent into the combustion chamber through compressed gas to achieve high-temperature incineration.
4、 Selection suggestions
Select based on operating conditions:
Low pressure and high flow rate: Choose models with higher flow rates, such as SR150, SR175, and SR200.
High pressure and low flow: Choose models with higher pressure, such as SR100 and SR125.
Flow redundancy design: In actual selection, the flow should be slightly higher than the required value (usually leaving a margin of 10-20) to cope with changes in system resistance.
Brand and after-sales service: Famous brands often have higher prices, but their quality and after-sales service are more guaranteed.
Material selection: Fans made of different materials have varying durability and performance, resulting in differences in price. It is necessary to choose the appropriate material based on actual working conditions.
