Step 102：Determine the operating air velocity of the wind turbine in the clarifier.
As an implementation, the operating air velocity of the wind turbine in the determination clarifier, including：
Obtain the revolution of the wind turbine in the clarifier；
The operating air velocity of the wind turbine in the clarifier is determined according to the revolution.
If for example, monitoring blowing machine in 30 seconds has turned 200 turns, determine that the operating air velocity of the wind turbine in the clarifier is
400 turns per minute.

The operating air velocity of the wind turbine in the clarifier is determined based on the current operation mode.
If for example, detect that the clarifier is in sleep pattern, the correspondence based on operating mode and operating air velocity,
It can determine the operating air velocity of wind turbine corresponding with the sleep pattern.
Step 103：Wind speed corrected parameter is determined according to the operating air velocity.
As an implementation, described that wind speed corrected parameter is determined according to the operating air velocity, including：
Speed interval where determining the operating air velocity；
Search the wind speed extent of amendment to match with the place speed interval；
Wind speed corrected parameter is selected from the wind speed extent of amendment.
As an example it is assumed that speed interval be divided into [a1, a2], (a2, a3], these three sections (a3 ,+∞), and it is described
The wind speed extent of amendment that place speed interval matches is specific as follows：Corresponding to speed interval [a1, a2], wind speed extent of amendment is
[b1, b2]；Corresponding to speed interval (a2, a3], wind speed extent of amendment be [b3, b4]；Corresponding to speed interval (a3 ,+∞), wind

Whole or setting, can also set or adjust according to the operating mode of clarifier.For example, if it is determined that speed interval be [a1,
A2], then a wind speed corrected parameter is selected from this section [b1, b2].
Here, a1 is less than a2, and a2 is less than a3；B1 is less than b2, and b3 is less than b4, and b5 is less than b6.
Step 104：The service life is modified based on the wind speed corrected parameter, obtains the new of the strainer
Service life.
As an implementation, described that the service life is modified based on the wind speed corrected parameter, it obtains
The new service life of the strainer, including：
Based on the wind speed corrected parameter, product calculation is carried out to the service life, obtaining the new of the strainer makes
Use the service life.
For example, speed interval where operating air velocity is [a1, a2], is to be selected in [b1, b2] from wind speed extent of amendment
Wind speed corrected parameter be denoted as d1, then strainer service life percentage=(power of fan attenuation percentage * m%+ run times hundred
Divide than * n%+ purge amount percentage * p%+ purification efficiency percentage * q%) * wind speed corrected parameters d1.Wherein, m+n+p+q=
100.For example, operating air velocity, at [300,500] section, the interval of wind speed corrected parameter d1 is [0.8,0.9].
Again for example, speed interval where operating air velocity be (a2, a3], be choosing in [b3, b4] from wind speed extent of amendment
Fixed wind speed corrected parameter is denoted as d2, then strainer service life percentage=(power of fan attenuation percentage * m%+ run times
Percentage * n%+ purge amount percentage * p%+ purification efficiency percentage * q%) * wind speed corrected parameters d2.Wherein, m+n+p+q=
100.For example, operating air velocity (500,700] section when, the interval of wind speed corrected parameter d2 is [0.9,1.1].
Again for example, speed interval where operating air velocity is (a3 ,+∞), is choosing in [b5, b6] from wind speed extent of amendment
Fixed wind speed corrected parameter is denoted as d3, then strainer service life percentage=(power of fan attenuation percentage * m%+ run times
Percentage * n%+ purge amount percentage * p%+ purification efficiency percentage * q%) * wind speed corrected parameters d3.Wherein, m+n+p+q=
100.For example, operating air velocity, at 700 or more, the interval of wind speed corrected parameter d3 is [1.1,1.2].
In the embodiment of the present invention, it is contemplated that the dust removal ability of strainer has relationship, operating air velocity with complete machine operating air velocity size
When bigger, strainer clean-up effect is better, and the dust of absorption is more, strainer life time decay it is faster；Operating air velocity is got over hour, strainer
Clean-up effect reduces, and the dust of absorption is reduced, and strainer life time decay is slack-off, so the strainer service life calculates, introduces an operation
Therefore wind speed corrected parameter first calculates the service life of strainer, by the wind speed corrected parameter determined to calculated use
Service life is modified and finally obtains the new service life of the strainer, thus the method for determination of this strainer service life is more
Add the true service life for meeting strainer.
