Waterworks Survey

Yundong Sewage Treatment Plant Has A Daily Water Treatment Capacity Of 2,000 Tons. The Process Is Micro-Porous Aeration A2O Treatment Process. The Fan Room Has Four Roots Fans, And Two Or Three Fans And One Roots Stand-By Fan Are Operated Under The Current Working Conditions.

2.2 Customer Requirements

According To The User's Requirements, The High-Efficiency Air Suspension Centrifugal Blower Of Henan Zengkun Machinery Is Selected To Replace The Roots Blower.

2.3 Current Roots Blower Condition:

Model, Maximum Air Volume (Q) Boost, Rated Power, Number Of Units In Use

RSE 150 ,18.03 M3/Min ,58.8 Kpa ,35 KW ,3

Existing Working Conditions:

Total Air Volume: 54.09 M3/Min, Power: 105 KW Pressure Gauge Shows Pressure: 70 Kpa, So The Actual Consumption Power Should Be Greater Than 105 Kw.

Considering The Above Data, The Most Suitable Model For This Project Is GF100-0.7, Which Can Replace Three Roots Blowers. Selected Model Parameters:

Model, Maximum Air Volume (Q) Boost, Rated Power, Unit Number

GF100-0.7 ,64m3/Min, 70Kpa ,75kW, 1

Note: Each Blower Adopts Real-Time Frequency Conversion Control, That Is, It Can Automatically Adjust The Air Volume And Pressure According To The Set Air Volume And Pressure Independently, And It Can Also Be Centralized And Coordinated Control By The Central Control Room. Each Blower Equipped In The Same Blower Room Is Standby For Each Other.

Air Volume Control Range: 35 M3/Min To 64 M3/Min

Energy Conservation Calculation:

Energy Saving Data Comparison

The Energy-Saving Comparison Of Zengkun Air Suspension Centrifugal Blower And Existing Multi-Stage Centrifugal Blower Under The Same Working Conditions Is As Follows:

1. Comparing Data Of Fan Under The Same Working Condition

Model (Q) ,Boost Volume ,Quantity In Use,Rating Power ,Operating Power

GF100-0.7 ,64m3/Min ,70Kpa, 1 Set,75KW, 59kw

Existing Roots Blower 54.06m3/Min ,58.8Kpa ,3 Sets ,105kW ,105kW

2. Energy-Saving Calculation

The Calculation Shows That Under The Same Working Conditions, The Energy-Saving Capacity Of Zengkun Mechanical Air-Float Fan Is 31 KW Per Hour And The Energy-Saving Efficiency Is 34% Compared With The Original Roots Fan.

Name, Power Consumption Per Unit, Number Of Units, Total Power Consumption

Former Roots Blower 30 KW/H, 3 Sets,105 KW/H Field Blower Data

Field Measurement Of Zengkun Air Floating Fan 59kW/H, 1 Set ,59kW/H Workshop

Energy Saving Calculation 31 KW/H ,1 Set, 46 KW/H

Daily Power Saving 46 X 1 X 24 = 1104 Kw

Annual Power Saving 1104 *365 = 402960 Kw

According To 0.55 RMB/Degree, 402960*0.55=221628 RMB

1. Structural Principle Comparison:

Traditional Fans Are Mostly Driven By Gears Or Belts, Equipped With Gearboxes, Couplings, Belts And So On. There Are Efficiency Losses In The Transmission Process. Air Suspension Blower Adopt Direct Connection Technology, Impellers And Motor Rotors Are Directly Connected, The Transmission Efficiency Reaches 100%.

2. Bearing Power Comparison (100KW Fan As An Example)

Traditional Roots Fan And Multi-Stage Centrifugal Fan Bearings Adopt Deep Groove Ball Rolling Bearings. The Power Consumption Of Bearings Is About 1.5KW During Operation. Most Single-Stage High-Speed Fans Use Tilting Pad Oil Film Bearings, Which Produce About 15KW Power Consumption In High-Speed Rotating Type. Air Bearings Have No Physical Contact And Friction, And Only Exist Wind Friction Loss, About 200W.

3. Motor Efficiency Comparison

The Traditional Squirrel Cage Induction Motor Has Poor Speed Regulation Performance, Small Starting Moment, And Efficiency Is Close To 90% At Rated Power. The Efficiency Decreases Sharply At Variable Power Output, And Only 72% At Rated Power 50%. The Efficiency Of ZK High-Speed Permanent Magnet Motor Is 97%. Permanent Magnet Motor Can Be Adjusted In A Wide Range, Even At 50% Power Output, The Efficiency Is Still 92%.

4. Comparisons Of Impeller Efficiency

Roots Blower Fan Is A Closed Two-Dimensional Flow Impeller, Which Uses Multi-Stage Compression, Low Flow Efficiency, And Variable Efficiency Is Only About 75%. ZK Air Float Fan Adopts Advanced Three-Dimensional Flow Impeller Technology, Single Compressor Compression, Efficiency Up To 92%.

5. Frequency Conversion Speed Regulation System + PLC Control

Frequency Conversion Efficiency Up To 97% Of The Converter And High-Speed Motor Perfect Match, Can Meet The Fan 50% - 100% Wide Range Of Flow Accurate Regulation, To Ensure That The Fan In The Changing Conditions Of Efficient Operation. PLC Reserves Remote Communication Ports, And Uses Modbus-RTU, Modbus-TCP/IP Mode To Communicate With Central Control System Remotely To Realize The Remote Operation Of Fan. Through The Selection Of Coordinating Cabinet, The Parallel Coordinated Operation Of Multiple Fans Can Be Realized.
