In the north, central heating is the main form of heating at present. Central heating means that the hot water supplied by the boiler room is piped to the radiators in each relevant room, and the heat is dissipated and then returned to the boiler for recycling. The heat in the boiler room Water is mainly heated by burning coal, and the flue gas SO2, NO2, etc. will be generated. If it is not treated, it will be discharged into the atmosphere and pollute the environment. This does not conform to the current national energy conservation and environmental protection policy, so the current general method is to use centrifugal The fan desulfurizes the exhaust gas produced by burning coal and sends it into the dust bag. This article introduces the application of the easy-to-drive CV3100 series frequency converter in the city heating system.

 

Introduction of customer's field application:

 

Use 4 sets of CV3100-4T4000M, drive 4 sets of centrifugal fans through the frequency converter, and send the exhaust gas produced by burning coal into the dust bag for collection and treatment to protect the environment.

Summary

 

The use of frequency conversion technology reduces mechanical impact and impact on the power grid, and reduces maintenance. At the same time, the easy-drive CV3100 series inverter has the protection functions of overvoltage, overcurrent, overload, undervoltage, overheating, etc., to ensure the reliability of the equipment Safe and continuous operation. In short, frequency converter speed regulation has been used more and more in boiler heating and centrifugal fan speed regulation with its high efficiency, low energy consumption and good stability, and it is worthy of promotion in all walks of life in society.
