New wind turbine is a kind of simple and effective air cleaning facility, it can make room air generate cycle, one side handle
The air discharge of foul indoor is outdoor, on the other hand outdoor ozone after the measures such as sterilizing, filtering, then is input to
Interior, to make room air keep fresh clean.
Wherein, strainer is the critical component for determining new wind turbine purification efficiency, new wind turbine in actual use, strainer
Windage can increase with the increase of adsorption particle object, to cause in the case where wind speed is constant under the air output of wind turbine
Drop can also decline therewith to the detergent power and purification efficiency of new wind turbine.
Since strainer has service life, the strainer of different stage to the filter capacity of different diameter airborne particle not yet
Together, and difference is very big, it is therefore necessary to which be used for the service life is monitored in real time, to replace strainer in time.
Currently, used strainer life tests mode is usually timing mode in industry, i.e., using with clocking capability
Hardware or software records strainer usage time, user will be reminded to replace after reaching default service life.But this detection
The accuracy of mode is extremely low, because the strainer of different stage its service life has very big difference, by particle size, actually makes
It is also very big with the influence of the factors such as environmental aspect, user's use habit, therefore the service life of strainer is not linear decrease,
Following two problems will produce using simple timing mode：
1, when the actual life of strainer being not up to replacement condition, replacement will result in unnecessary waste, and then improve
The use cost of user；
2, it when exceeding its actual life in the detection service life of strainer, replaces not in time, the purification effect of new wind turbine can be reduced
Fruit, or even cause secondary pollution.
Based on above-mentioned present situation, it is necessary to a kind of inexpensive, high-precision strainer life detecting method is researched and developed, it is current to solve
The problems of in industry.
Invention content
In order to solve the above technical problems, the invention discloses a kind of new blower fan screen net life detecting method, including following step

Amount M4 is calculated by the following formula：M4=Q × (N1-N21) × T.
As a further improvement of the above technical scheme, described particle concentration N1, N21, N22, N3 include PM2.5 dense
Degree and PM10 concentration.
The beneficial effects of the invention are as follows：
1, its remaining life is accurately calculated according to the actual use situation of strainer, the service life of strainer can be grasped in real time
Situation, avoid too early replace strainer and caused by waste or too late replace strainer and caused by secondary pollution.
2, the particle concentration data of outdoor air, and the sky detected using each particulate matter sensors are obtained from high in the clouds
The actual value of particle concentration is as calculation basis in gas, while considering new wind turbine computational methods under different operational modes
Difference, therefore result of calculation is more accurate.
3, this method considers interdiction capability of the different strainers to the particulate matter of different-grain diameter, to be directed to different strainers
Using different computational methods, thus it is more accurate to the detection in strainer service life.
Specific implementation mode
Technical scheme of the present invention is clearly and completely described below in conjunction with specific embodiment, it is clear that described
Embodiment be only a part of the embodiment of the present invention, instead of all the embodiments.
Embodiment one：
The new blower fan screen net life detecting method of the present embodiment, mainly for Single Pollution source (PM2.5 or PM10) and
New wind turbine with single type strainer carries out the life tests of strainer, and detection method includes the following steps for this：
