Aeration tank air regulating valve
Detailed introduction of the air regulating valve in the aeration tank, combined with technical characteristics, application scenarios, and practical case studies:
1、 Core functions and technological advantages
The air regulating valve of the aeration tank is mainly used to accurately control the aeration amount of the blower, and achieve linear distribution of air flow by adjusting the valve core opening. Its core advantages include:
Significant energy saving: Installing a single blower can reduce power loss by up to 30%, and overall aeration energy consumption can be reduced by 40% -70%
High precision control: adopting a diamond shaped valve body design, the air flow regulation linearity is better than traditional butterfly valves, and the response speed is faster
2、 Comparison of mainstream product types
Types, Applicable Scenarios, Performance Characteristics
Diamond shaped regulating valve for sewage plant aeration distribution has a small volume, light weight, and high linearity in flow regulation
Large industrial aeration system with piston type regulating valve, high pressure resistance (PN64), long service life but high cost
Electric circular valve intelligent aeration system (DO feedback control) supports 4-20mA signal and is compatible with feedforward/feedback control
3、 Typical application cases
A certain recycled water plant in Beijing: By installing intelligent regulating valves, the unit power consumption of the blower has been reduced by 15%, and the power consumption of TN removal has been reduced by 10.7%
Chemical wastewater treatment plant: using corrosion-resistant stainless steel valve body, the service life is extended by three times when treating sulfuric acid containing media
4、 Selection suggestions
Medium characteristics: Corrosive wastewater requires the use of 904L stainless steel or Si Ti Lai alloy valve cores
Control mode: Prioritize selecting intelligent valves that support both feedforward and DO feedback modes to achieve dynamic response
