Roots blowers are widely used in industrial fields that require stable gas sources or vacuum environments due to their characteristics of forced gas transmission, constant flow rate, no oil pollution, and strong pressure adaptability. The following is an analysis of its main applicable scenarios and specific application scenarios:
1、 Environmental protection field: sewage treatment and waste gas treatment
Sewage treatment aeration
Function: Provide dissolved oxygen for the aeration tank in the activated sludge process and promote microbial decomposition of organic matter.
Advantage:
Stable flow rate, fluctuation of dissolved oxygen content ≤ ± 0.5 mg/L, ensuring treatment efficiency.
Oil free lubrication design avoids lubricating oil pollution of water bodies and meets environmental protection requirements.
Case: Urban sewage treatment plants, industrial wastewater treatment stations (such as chemical and paper industries).
Waste gas treatment and ventilation
Function: Transport dusty and corrosive gases (such as sulfur dioxide and hydrogen chloride) to the scrubbing tower or incinerator.
Advantage:
Corrosion resistant materials (such as stainless steel and fiberglass) are optional to adapt to harsh working conditions.
Can be equipped with explosion-proof motors for handling flammable and explosive gases.
Case: Flue gas treatment in garbage incineration plants, acid mist treatment in electroplating plants.
2、 Aquaculture: oxygenation and water circulation
Micro porous oxygenation system
Function: By using a Roots blower to deliver high-pressure air to the bottom of the pond, small bubbles are formed through a microporous aeration disc to improve dissolved oxygen efficiency.
Advantage:
The dissolved oxygen content can reach 5-8 mg/L, and the breeding density can be increased by 30% -50%.
Energy saving of over 30% (compared to traditional waterwheel aerators).
Case: High density aquaculture (such as shrimp and sea bass), factory based circular aquaculture.
Water circulation and purification
Function: Drive the circulation of water between the aquaculture pond and the filtration system to maintain stable water quality.
Advantage: Constant flow rate, avoiding water quality deterioration caused by flow fluctuations.
3、 Pneumatic conveying: transportation of powder and granular materials
Powder conveying
Function: Convey powdered materials such as cement, flour, starch, plastic particles, etc.
Advantage:
The conveying distance can reach 500m, and the conveying capacity is stable at 10-100 t/h.
Closed conveying to avoid dust leakage and meet environmental protection requirements.
Case: Raw material transportation in cement plants, flour transportation in grain processing plants.
Particle material transportation
Function: Transport coal powder, fertilizer particles, chemical raw materials, etc.
Advantage:
Can transport materials with dust content ≤ 100 mg/m ³ and particle size ≤ 0.1 mm.
Wear resistant design (such as hard alloy rotors) extends equipment life.
Case: Raw material conveying and coal powder boiler feeding system in fertilizer plant.
4、 Vacuum application: Roots vacuum pump combination system
Industrial vacuum packaging
Function: In series with the water ring vacuum pump, form a Roots water ring vacuum unit for rapid vacuuming.
Advantage:
