Working Princple of Dedusting System Frequency Conversion

All over the world is puzzled by the shortage of energy,and the energy situation is particularly serious in our country.Because the dust in some industries processing capacity is large,and the continuous work time is long, in order to save the economic cost of operation,Lihui deduster,besides it meets the low running resistance,and low Power consumption requirements,for customers,it equips with the mature frequency conversion control technology of fan, provides a comprehensive and effective energy saving scheme,and in air automatic air valve and the negative pressure trans-ducer,it uses frequency conversion control system to monitor the wind tube pressure changes, in according to the equipment use situation to adjust the frequency and speed of the fan,easy to achieve dedusting system of air supply and demand matching,not just waste kilowatt hour.For fans load in generalthe air volume Q and rotational speed n is in 1 power relationshippower dissipation and rotational speed n is 3 power relationship.

The formula is as follows:

Q=Q0(n/n0)         P=P0(n/n0)3

 

Through matching the fan speed regulation and frequency converter,keep the power consumption always being lowest.

 

The shadow part of the figure is the actual energy saving.

 

For example:motor power of a fan is 55KW,when the required air quantity is reduced by 20% , power dissipation of whole power dissipation is 51%,the power consumption is 28.16KW,power saving is 48.8%; when the required air quantity is reduced by 50%,power dissipation is 12.5%,the power dissipation of whole power dissipation is 6.875KW5,the power saving is 87.5%,so the energy saving is very considerable.
