Step 401：The gross decontamination amount of filter screen in clarifier is obtained, and calculates the accumulation purge amount of the filter screen.

CCM=(0.48 × CG-28) × S × 2.4 × T

Step 402：The accumulation purge amount of gross decontamination amount and the filter screen based on the filter screen, determines the net of the filter screen Change percentage parameter.

Step 403：Purification percentages parameter based on the filter screen, determine the first service life of the filter screen.

The determination method of the second service life in the embodiment of the present invention is described in detail below.

Fig. 5 is the schematic flow sheet of the determination method of the second service life of the embodiment of the present invention, as shown in figure 5, described Method comprises the following steps：

Step 501：The gross decontamination amount of filter screen in clarifier is obtained, and the gross decontamination amount based on the filter screen calculates the filter The terminal life of net.

CCM=(0.48 × CG-28) × S × 2.4 × T

Therefore, the terminal life of the filter screen is calculated based on below equation：T=CCM/ (0.48 × CG-28) × S × 2.4}。

Step 502：Terminal life based on the filter screen, the dust concentration value of the clarifier local environment and institute The actual run time of filter screen is stated, determines the equivalent run time of the filter screen.

In the embodiment of the present invention, the dust concentration value of clarifier local environment and the concentration value of standard environment are typically different, Run time corresponding to the concentration value of standard environment is referred to as equivalent run time, and the dust concentration value of clarifier local environment is corresponding Time be referred to as actual run time, actual run time is converted into equivalent run time can be based on below equation：t_eq= (CN/CG)×t；

Such as：The dust concentration value of clarifier local environment is CN=50ug/m³, the dust concentration value of standard environment is CG =250ug/m³, it is assumed that filter screen actual run time is 1 hour, then the equivalent run time of filter screen is t_eq=(50/250) × 1 Hour=12 minutes, i.e., user is in 50ug/m³Mean dust concentration under use a hour, during the loss for the filter screen being converted to Long (namely equivalent run time) is 12 minutes.

Step 503：The terminal life of equivalent run time and the filter screen based on the filter screen, determines the filter The run time percentage parameter of net.

Specifically, the ratio of the equivalent run time of the filter screen and the terminal life of the filter screen is calculated, as institute State the run time percentage parameter of filter screen.

Assuming that the equivalent run time of filter screen is t_eq, the terminal life of filter screen is T, then filter screen run time percentage Parameter is x=t_eq/ T, wherein, x is run time percentage parameter.

Step 504：Run time percentage parameter based on the filter screen, determine that the second of the filter screen uses the longevity Life.

In the embodiment of the present invention, the run time percentage parameter is bigger, then the service life of the filter screen is smaller；Institute State that run time percentage parameter is smaller, then the service life of the filter screen is bigger.

Because the equivalent run time of filter screen is less than or equal to the terminal life of filter screen, therefore x span is 0 to 1.

Specifically, the span (namely 0 to 1) of the run time percentage parameter is divided into N number of number range, N is integer and N >=2, wherein, each number range corresponds to a service life；Determined in N number of number range Go out the number range belonging to the run time percentage parameter being calculated, as target value scope；Determine described Service life corresponding to target value scope, the service life as the filter screen.

Such as：5 number ranges are divided into by 0 to 1, be respectively (0,20%], (20%, 40%], (40%, 60%], (60%, 80%], (80,100%), wherein, service life corresponding to (80,100%) is 3 months, (60%, 80%] corresponding to Service life is half a year, (40%, 60%] corresponding to service life be 1 year half, (20%, 40%] corresponding to service life be 2 Year, (0,20%] corresponding to service life be 3 years.Assuming that x belong to (0,20%], then the service life of filter screen be 3 years.Certainly, The determination method of the service life of filter screen is not limited thereto in the embodiment of the present invention, can also be calculated by below equation The service life of filter screen：T-t_eq=T-x × T=T × (1-x), wherein, T be filter screen terminal life, t_eqFor having for filter screen Imitate run time.

Fig. 6 is the schematic flow sheet of the determination method of the first service life of the embodiment of the present invention, as shown in fig. 6, described Method comprises the following steps：

Step 601：First at the air outlet is detected using the first dust sensor for being arranged at clarifier air outlet Dust concentration value, and detect the of the air inlet using the second dust sensor for being arranged at the clarifier air inlet Two dust concentration values.

In the embodiment of the present invention, the first dust sensor is provided with the air outlet of clarifier, in the air intake of clarifier The second dust sensor is provided with mouthful.In one embodiment, the first dust sensor and the second dust sensor can be PM2.5 sensors, PM2.5 sensors can be used for detecting the dust concentration value in air, i.e. PM2.5 values.PM2.5 sensors Operation principle is the scattering phenomenon that the scattering principle based on light, particulate and molecule can produce light under the irradiation of light, at the same time, The energy of partial illumination light is also absorbed, can be by being scattered around particle when a branch of collimated monochromatic ligth incides tested particle field With the influence of absorption, light intensity will be attenuated, and can thus try to achieve relative attenuation rate of the incident light by concentration field to be measured, and The size of relative attenuation rate substantially can linear response field dust to be measured relative concentration, the size of light intensity and through opto-electronic conversion Electric signal power is directly proportional, can be in the hope of relative attenuation rate by measuring electric signal, and then can determines powder in field to be measured The concentration of dirt.

The second dust concentration value that second dust sensor detects represents the dust concentration value before purification of air, and first The first dust concentration value that dust sensor detects represents the dust concentration value after purification of air.

It is worth noting that, the first dust sensor and the second dust sensor in the embodiment of the present invention can also merge Into a dust sensor, in this case, dust sensor can be realized to air inlet by changing detection direction Dust concentration and the dust concentration of air outlet are detected respectively.

Step 602：Based on the first dust concentration value and the second dust concentration value, determine in the clarifier The purification efficiency of filter screen.

Typically, the first dust concentration value is less than or equal to the second dust concentration value, namely：Dust concentration value after purification of air Less than or equal to the dust concentration value before purification of air.First dust concentration value is smaller relative to the second dust concentration value, then represents The Dust Capacity that strainer filtering falls is bigger；Similarly, the first dust concentration value is bigger relative to the second dust concentration value, then represents filter screen The Dust Capacity filtered out is smaller.In particular cases, the first dust concentration value is equal to the second dust concentration value, and at this moment, filter screen does not have Play any purifying functions, it is seen then that filter screen in this case is the filter screen scrapped.

In the embodiment of the present invention, the ability of strainer filtering dust can be characterized by the purification efficiency of filter screen, based on this, The net of filter screen in the clarifier can be calculated by the first dust concentration value and the second dust concentration value Change efficiency.

In one embodiment, the net of filter screen is determined by the ratio of the first dust concentration value and the second dust concentration value Change efficiency, at this moment, ratio is bigger, and the purification efficiency that represents is lower, and ratio is smaller, and to represent purification efficiency higher.It can be seen that determine described net Changing the purification efficiency of the filter screen in device needs to perform following operation：Calculate the first dust concentration value and second dust is dense The ratio of angle value, the purification efficiency is obtained, the span of the purification efficiency is 0 to 1.

Certainly, the calculation of the purification efficiency of filter screen is not limited to dense by the first dust concentration value and the second dust The ratio of angle value determines, such as in another embodiment, passes through the second dust concentration value and the difference of the first dust concentration value Value determines the purification efficiency of filter screen, and at this moment, difference is bigger, and the purification efficiency that represents is higher, the smaller purification efficiency that represents of difference is got over It is low.

Step 603：Based on the purification efficiency of the filter screen, the 3rd service life of the filter screen is determined.

Specifically, the span (namely 0 to 1) of the purification efficiency is divided into N number of number range, N is integer and N >=2, wherein, each number range corresponds to a service life；Determine to be calculated in N number of number range The purification efficiency belonging to number range, as target value scope；Determine to make corresponding to the target value scope With the life-span, the service life as the filter screen.

Such as：X represents purification efficiency, x=(the first dust concentration value/second dust concentration value) × 100%.Due to first Dust concentration value is less than or equal to the second dust concentration value, and therefore, x span is 0 to 1, and 5 numerical value models are divided into by 0 to 1 Enclose, be respectively (0,20%], (20%, 40%], (40%, 60%], (60%, 80%], (80,100%), wherein, (80, 100%) service life corresponding to is 3 months, (60%, 80%] corresponding to service life be half a year, (40%, 60%] it is corresponding Service life be 1 year half, (20%, 40%] corresponding to service life be 2 years, (0,20%] corresponding to service life be 3 years.It is false If x belong to (0,20%], then the service life of filter screen be 3 years.
