Roots blowers are widely used in various fields due to their stable flow rate, wide pressure range, and compact structure, as follows:
1. Wastewater treatment:
Aeration tank oxygen supply: In sewage treatment processes such as activated sludge method, Roots blower blows air into the aeration tank to provide sufficient oxygen for microorganisms, enabling them to decompose organic matter in sewage and achieve the goal of purifying water quality.
Stirring and mixing: The air flow generated by the Roots blower is used to stir the sewage, fully mixing the pollutants in the sewage with the treatment agent to improve the treatment effect.
2. Aquaculture:
Pond oxygenation: Roots blower injects air into the water through an aeration system to increase the dissolved oxygen content in the water, providing a good living environment for aquatic organisms such as fish and shrimp, and improving aquaculture density and yield.
Circulating aquaculture: In the circulating aquaculture system, Roots blowers are used to promote water circulation, allowing water to continuously flow between aquaculture ponds, filtration equipment, oxygenation equipment, etc., maintaining stable water quality and aerating the water.
3. Material transportation:
Dust conveying: In industries such as chemical, building materials, and grain, Roots blowers can be used to transport powdered materials such as cement, flour, and coal powder. The material is mixed with air through a pipeline to form a gas-solid two-phase flow, and the material is transported to a designated location using the airflow pressure generated by a Roots blower.
Particle conveying: Roots blowers can also be used to transport granular materials such as plastic particles and grains, achieving continuous and stable material conveying during the conveying process and improving production efficiency.
4. Metallurgical industry:
Blast furnace blowing: In ironmaking blast furnaces, Roots blowers provide high-pressure air to the blast furnace, allowing coke to burn fully inside the furnace, producing high temperature and reducing gases, providing heat and reducing agents for the reduction reaction of iron ore, ensuring the smooth progress of the ironmaking process.
Converter steelmaking: During the converter steelmaking process, a Roots blower is used to blow oxygen or oxygen enriched air into the converter, causing impurities such as carbon, silicon, and manganese in the molten iron to undergo oxidation reactions with oxygen, in order to remove impurities and adjust the composition of the molten steel.
5. Chemical industry:
Gas transportation and pressurization: In the chemical production process, it is often necessary to transport various gases to different production links or equipment. Roots blowers can transport and pressurize gases such as hydrogen, nitrogen, chlorine, etc. to meet the requirements of the production process.
Vacuum packaging: In the packaging process of some chemical products, Roots blowers can be used in conjunction with vacuum systems to extract air from the packaging container, create a vacuum environment, and then fill it with protective gas to extend the shelf life of the product.
6. Electric power industry:
Boiler ventilation: In thermal power plants, Roots blowers are used to provide the air required for combustion to the boiler, allowing the fuel to burn fully and improving the thermal efficiency of the boiler. At the same time, the smoke produced by combustion is discharged from the boiler to maintain pressure balance inside the boiler.
Ash removal system: Roots blowers can be used in pneumatic ash removal systems to transport the fly ash produced by boiler combustion through pipelines to ash storage or designated locations for storage or treatment, avoiding environmental pollution caused by fly ash.
7. Other applications:
Vertical kiln blower: In cement production, Roots blower serves as a combustion supporting fan, which sends combustion gas from the bottom of the kiln to help materials fall vertically inside the kiln and achieve clinker firing.
Homogenization warehouse mixing: The compressed gas discharged by the Roots blower 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: In tunnel ceramic kilns, vertical magnesia kilns, and glass pool furnaces, Roots blowers are used to atomize fuel, dividing the oil flow into fine strands and trapping bubbles, forming a group of small diameter droplet mist.
Promoting chemical changes: In the gas-solid two-phase contact of chemical changes, the compressed gas provided by the Roots blower 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 dust, and a vacuum pump to extract the gas from the dust and clean various loose particles and dust.
Transportation and filling of food and medicine: In the food and medicine industry, Roots blower can be used to transport and fill all kinds of powdery, granular and liquid substances, such as Rice noodles, glucose, tablets, etc.
Dust removal, desulfurization, denitrification: In the field of environmental protection, Roots blowers can be used for dust removal, desulfurization, denitrification, etc., reducing environmental pollution.
Transportation of pulp and printing ink: In the paper and printing industry, Roots blowers can be used to transport substances such as pulp and printing ink.
In summary, Roots blowers play an important role in multiple fields, demonstrating their wide range of applications and practicality.
