The Roots blower has no internal compression, so when the exhaust is exhausted, the higher-pressure air in the pipe network is reversely charged back into the compression chamber, forming gas ramming, which produces high low-frequency air noise, and the vibration of the equipment is also very large, which greatly reduces the pressure of the screw fan. Reduced noise and vibration, 15-30dB lower than Roots blower noise (A).
Whether it is municipal sewage or corporate sewage (including textile printing and dyeing, leather, medicine, chemical industry, paper making, breeding and slaughtering, etc.), it must be treated up to the standard before it can be discharged into natural water bodies or recycled. In the sewage treatment process, a key link is the oxygen supply for biological treatment, that is, the aeration link. During the operation of several common process sewage treatment plants, the energy consumption of the oxygen supply system for biological treatment accounts for 50%-55% of the energy consumption of the whole plant. There is a lot of room for reducing the consumption of the biological treatment oxygen supply system. Choosing an efficient blower will directly bring considerable economic benefits.
Lower energy costs (up to 80% of blower life cycle costs), innovative screw blower technology resulting in less downtime for maintenance.
Lower energy costs (up to 80% of blower life cycle costs), innovative screw blower technology for lower maintenance downtime, extremely wide flow and pressure operating ranges. Nonwoven production, air knife, texturing flow adjustable to influence fiber properties, energy efficient blower capable of continuous 24/7 operation with low operating costs. Point-of-use installation without noise protection measures.
In thermal power generation, steel, glass, chemical and other factories, a large number of boilers are burned, and the flue gas emitted by them contains a large amount of sulfur, nitrate and other substances, which seriously pollutes the atmosphere. This requires treatment such as desulfurization and denitrification before discharge, and can only be discharged into the atmosphere after reaching the standard. In desulfurization and denitrification facilities, oil-free screw blowers are required as oxidation fans.
Under the same air volume and air pressure, the power consumption required by the screw blower is much smaller. Compared with the traditional Roots blower, the screw blower may save up to 35%, the higher the pressure, the more significant the energy saving effect, and the average energy saving is 20%. The energy saving of oil-free blower can reach 20%-50%.
Q: What is the noise and vibration performance of a screw blower compared to a Roots blower?
The screw blower greatly reduces noise and vibration, offering levels that are 15-30dB lower than a traditional Roots blower. This is because Roots blowers lack internal compression, which causes high low-frequency gas ramming noise and heavy vibration.
Q: Why is energy saving so critical in sewage treatment aeration applications?
In sewage treatment plants, the energy consumption of the oxygen supply (aeration) system for biological treatment accounts for 50%-55% of the entire plant's energy consumption. Choosing an efficient blower directly reduces this consumption and brings considerable economic benefits.
Q: What benefits do screw blowers bring to pneumatic conveying and fermentation processes?
Screw blowers lower energy costs (which can make up to 80% of the blower's life cycle costs) and use innovative technology that results in less maintenance downtime, wide flow ranges, and extremely wide pressure operating ranges.
Q: Can the screw blower be used for desulfurization and denitrification?
Yes. In facilities like thermal power generation, steel, and chemical plants, oil-free screw blowers are required as oxidation fans in the desulfurization and denitrification process to clean flue gas before it reaches discharge standards.
Q: What is the average energy-saving rate of a screw blower compared to a Roots blower?
Under the same air volume and air pressure, a screw blower can save up to 35% compared to traditional Roots blowers, with an average energy saving of 20%. For oil-free blowers, the overall energy saving can reach 20%-50% depending on the pressure level.
